TCCD/TCC5 Overclocking Database and Discussions

Having overclocking problem with your TCCD? Some questions that we usually overcome with TCCD and TCC5 chips.......

So... I hope this is the best thread to share our results on TCCD/TCC5 discussions. I don't see any relevance in separating TCCD and TCC5 as they are basically the same chip/ic, which is Samsung K4H560838F. To make this database possible, you guys need to post your best DDR speed which is stable enough to run SuperPi 32M. Don't forget to include your CPU-Z verification link. Necessary utilities like SuperPi mod and CPU-Z 1.30 is provided at the bottom of this posting.

Categories are divided to single channel and dual channel. 2x dual channel will be added if there is any. AMD or Intel does not matter, as long as it fulfills the requirement. Ranking is sorted according to the highest DDR speed, followed by timing and then voltage. Lower voltage will have better advantage compare to higher timing.

Rules
Just like any other database, please include your:
1. CPU, chipset and FSB:RAM divider used.
2. RAM brand, TCCD or TCC5.
3. RAM speed, timing and voltage.
4. Screenshot of SuperPi 32M (pass) with 2 CPU-Z which shows "CPU" and "Memory" section. Please use thumbnail or attach to the posting to make things neater. Avoid direct image linking if possible.
5. Include CPU-Z verification link.

Example:

http://valid.x86-secret.com/show_oc?id=41342
CPU: AMD Sempron 2800+
Chipset: nF3 250Gb
Divider: 5/06
RAM brand: 512MB OCZ EL DDR PC-3200 Platinum Rev.2 1.1 (TCC5)
Speed : 270MHz, 2.5-4-3-10 @ 2.8V
*Ignore screenie, it's just an example of posting template

This database purpose is to help others, rather than for show-off purpose. Each person can post more than one result, as long as it came from different brand. There is no need to cheat to get into the chart, as there is no minimum ranking for this database.

Utilities:
CPU-Z v1.30
SuperPi mod 1.4

Have you tried DRAM Drive Strength - Level 7?

32 Byte Granularity - Disable(8 Bursts)

put 4bursts....
ur ram voltage wil be lower as 2.8 or 2.9

last times i oso face tis problem n run my tccd at 3.3v
flash to 618-3 bios n no hav 8bursts for me...so i choose 4 bursts n my ram vdimm drop til 2.9v@300fsb

no luck yet so far.... but it's getting interesting

will restart from the scratch

what i like about my TCC5 is that it runs DDR400 2-2-2-5 with only 2.6V, 100% stable with memtest, prime and superpi32M

my TCCD ddr600 memtest at 2.5v

play around with your Max async and read preamble.. try a few combination

i wanted to try 2.5V but when i put 2.5V the reading is still around 2.6V

but heck... the default voltage OCZ suggested was 2.75V

no much luck yet

i can do DDR600 2.5-4-3-7 at 2.8V with some errors during memtest. can run superpi 1M and run sisandra memory benchmark only

maybe it's just my Palermo D0 memory controller at the limit

may i know wat diffrent between tcc5 n tccd??
timing??

TCC5 is binned at 466MHz by Samsung
TCCD is binned at 500MHz by Samsung

both are from the same die (revision F), which means they should have the same overclocking potential.

lower speed binning actually reduces manufacturing cost

http://valid.x86-secret.com/show_oc?id=27814
2.5-4-4-8@321*9@3.0v@1:1

but after i burn in for few day...now can make it at 2.5-4-3-6 2.9v 321@1:1

no time to benmark jor...kinda lazy now...hahaha

no lah...fx-57 more power full
so u fast fast get 1 unit sandy loh...

cos i wanna change my ram soon...i wanna find a tccd ram tat can do at ddr600@2-2-2-5@1:1

but ur ram oso not bad, can do at 2.5-4-3-6@ddr600

memtest86 wit 12hours then stop for a while...if u got a good cooling then no need to stop... n i found prime95 is a good software to burn in ur pc...

cos every time i open 2(means run prime95 two at the same times) n run fft at 1024mb.

290*10 wil fail at 1h16min at the 1st... mb my cooling no really good...
my ram d@mn hot

TCCD ddr600 2-2-2-5???

ur SanDiego is a gem.. keep it.. the SanDiegos i've seen have problem with TCCD.. including mine..

got such tccd ddr600 2-2-2-5 meh?

i tot... tccd ddr600 2.5-3-3-x-1T is already super

i argee too...cos my bh-5@2-2-2-5@1:1@3.7v can prime stable for 3hours at 265*11..without any problem

ya...tat y i need to find a good tccd can run at 2-2-2-5
i think onli geil can do it...but the price

babyelf gem...mind send to me n let me try the speed

1. babyelf - 8125 PTS - Gskill LE TCCD @ 7-3-3-2.5 @ @ 302 MHZ @ 1T @ 2.73 VDIMM

TCCD that runs 2-2-2-5 at what speed?

which geil can do what?

if u're talking about the Geil One memory u've been deceived by their marketing tactics..

They used a x4 multiplier (which is a bug on Athlon64) and actual ram speed is not DDR600 2-2-2-5.. it is lower

mind sharing your BH-5 alpha timings?


1. babyelf - 8125 PTS - Gskill LE TCCD @ 7-3-3-2.5 @ @ 302 MHZ @ 1T @ 2.73 VDIMM

that was with my other processor.. not my Sandiego.. my Sandiego don't like TCCD.. that's why you don't see me testing my TCCD on my sandiego

and also... CL1.5 by Geil also marketing gimmick, where the CL1.5 is actually non-existence in A64 memory timings

Geil sure got lotsa marketing gimmick eh?

3 possibilities
1. their engineers bodoh
2. their engineers didn't read A64 white paper
3. they know.. but mau tipu consumers

and btw..

there's 2 Geil One modules

one is BH-5 and one is TCCD..

their Geil One TCCD is actually not bad.. but a bit too pricey.. don't think i'll get one..

This post has been edited by babyelf: Aug 25 2005, 12:01 AM

i didt set all...onli set the timing...cos last time i buy all stuff, n i cant find gskill ram in lyn tat y i tempory use my old bh-5 to run 1st...

last times buy tis baby at rm400 onli 256 corsair 3200 rev1.1, on b'cos run at single channel n didt do any benmark, jus use tat ram to burn in my proc

but ur superpi using sandy vy fast wat...abt 27sec finish 1mb jor...

so 265 just 2-2-2-5 in bios? other timings on auto?

that superpi1mb is suicide shot.. nothing near stable.. maybe will get it higher soon.. just got this


Attached thumbnail(s)

My current setting at 2.8V with very minimum error in Memtest86+, maybe need more burn-in

(Using DFI nF3 250Gb 4/15 BIOS w/ 4Vdimm mod)

cannot run at ???
Row to Row delay (Trrd) - 02 Bus Clocks
Write recovery time (Twr) - 02 Bus Clocks
Write to Read delay (Twtr) - 02 Bus Clocks
Read to Write delay (Trwt) - 02 Bus Clocks

haven't tried that though

i tot lower timing is more stable

dunno loh...cos i can run 3dmark wit tis setting...if i put 3,3,2,3 or 3,2,2,3 got problem... but put it 2,2,2,2 then no problem jor

i oso pelik
mb u can try lah

hmm...here my old bh-5 run at 2-2-2-7@267@3.7v@1:1@1t

Eh? Whats BH-5 doing in a TCCD thread?

Anyways, I find that it is much easier to overclock 2x256MH TCCDs to 300+MHz with 1T than 2x512MB TCCDs.

Here's my setup doing 300MHz 2.5-4-3-7-1T @ 2.7V on Corsair 3200XL 2x256MB TCCD 513


My current highest stable record at 320MHz 2.5-4-4-8-1T 2.7V on 3200XL 2x256MB TCCD modules


My Setup: A64 3000+ WinChester - DFI LP UT nF3 Ultra-D (BIOS 705) - Corsair XMS 3200XL 2x256MB 2.7v - LTD 3x 1.7v - CPU 1.6v - vAGP 1.6v

Edit: All tests done in DUAL CHANNEL.

This post has been edited by pcmoddingmy: Aug 26 2005, 06:57 PM

nice one there dude

but 256MB modules sure can clock high easily due to the single bank factor

Yup.. its either that or my board hates dual sided memory module.

I found this thread informative so I have decided to pinned it up for easy reference.

Dont know whether is it a suitable place to post or not ..

Anything idea what cause failed ?

2x512MB Corsair TwinX DDR400 v1.4, running at 270MHz, 2.5-4-3-7,1T, 3.2v

memtest run >7hours same setting with3.0v no error.
but in window i need to adjust to 3.2v



here is my tweaker setting :

Try:

Max Async Latency to 8
Read preable to 6
Idle Cycle Limit to 256

ahpaul... i think your voltage is too high for only 270mhz ler...

try back down to 2.7v or 2.8v

yours are tccds right?

Which one more realible ? or should i said more trusted ?
Prime95 or SP2004 ?
The Prime95 failed but SP2004 still running no error yet..

This post has been edited by ahpaul82: Aug 30 2005, 05:16 PM

voltage too high?
but i think mine's TCCD is not as good as you guy one leh..


ok
i will try lower the voltage and kianwee setting .

Which test did you run?

find your maximum memory oc and tune the memory timings to get memtest86 pass at test #5, tune until you can get it run at 2.8V or less. if you're trying to run at 300mhz, put the vdimm at 2.9v

from there, after you can pass memtest86 #5, try to enter windows. if you cannot stable in windows, you might need to increase your chipset, agp or cpu voltage. or maybe u need to bump your agp speed to 67mhz. no need to alter your vdimm anymore.

Actually both are the same, using the same Lucas-Lehmer iterations. To stress the RAM, use In-place Large FFTs or Blend Tests. However, Blend test will use up all of your RAM and causing extreme lags. So, I prefer Large FFTs.

If you have Prime95 for some reason, try Windows MemTest (http://hcidesign.com/memtest/). Let it pass atleast 3000% coverage or 2 hours error free for maximum stability.

Edit: Screw BIOS Memtest!

This post has been edited by pcmoddingmy: Aug 30 2005, 07:50 PM

bios memtest purely tests the ram, that's why even OCZ still use this utility for testing.

when you go into windows..... any memtest based tool is affected by the processor and overall system stability also, that's why you can pass bios/dos memtest but cannot pass windows memory tester.

Im using Blend Test to test my RAM stability.

Thanks for the kianwee, soulfly and pcmoddingmy's sugguestion.
I will give it a try. Thanks a lot.

I think the max speed for my Corsair RAM can run is 275MHz only .
last time did a test with my Winchester and can run >8hours no problem but with kinda loose timing. i think is 2.5-4-4-8,1T, 3.2v.
I forgot how im able to do that timing last time.. >>>



Now don't think about RAM first,
test my processor how high can go but with low voltage ..

what do you mean by "cannot stable in windows" ? my GH run 235 @ 2-2-2-5 stable in memtest65#5 for more than 13hours and 240 @ 2-2-2-5 for more than 9hours but with 2 errors only. but come to windows, few minute later, the pc automatic reboot, increase the agp voltage or speed will make it stable?

Everybody is playing TCCD on Athlon64? I'm still playing around with AthlonXP only, hahahaa.

Well, i js got my Corsair TwinX1024-3200XL from Dinster bulk, testing it from the beginning. The RAM is running fine on 2.6V DDR400 @ 2-2-2-10. It's been primed for 60 hours in total.

Now trying DDR410 @ 2-2-2-11 with 2.6V, see how well it can be stressed

btw, i hope there are AXP users who use TCCD to post the results here

Try custom setting as it allows u to test the RAM at all time, not switching between CPU and RAM. These are the settings :

FFT : 8K to 4096K
Run in place FFT : UN ticked
RAM Size in used : up to u. I usually set to 64MB or 128MB.
Time : 1 minute.

I usually run for more than 2 days to obtain most stable results. Testing less than 8 hours cant give me high windows uptime as compare to 2 days.

btw, how's yr RAM performing now? Still using high volts or already switch to lower voltage. IMO, it should be able to run at 2.7 - 2.8V @ 275MHz. Good luck dude !

This post has been edited by charge-n-go: Aug 31 2005, 10:50 AM

One reminder to TCCD/TCC5 users, do not stress your RAM with high voltage like 3.3V and above, if not the RAM will lose their efficiency with lower voltage. This matter had been discussed in a few other forums.

That time forgot to take the A64 Tweaker screen ..

oh, mean you recommend custom setting than perset setting to test the RAM is it ?

somemore need to run 2days only can say system 100% stable ar ?

i stop test the RAM already.
now finding the max HTT my Venice can go . last time need >1.600v only can do 285HTT, after few days burn in, now my Venice able to do 285HTT with 1.525v, although i know is still quite high vcore, but compare last time, still ok la . (using stock fan and divider of coz ) i hope not my board holding me back .

As my fren told me, the 2x512MB Corsair TwinX PC3200 is using TCCD ramchip (default timing is 3-3-3-8), but i think not optimize as those high performance ram lor.. if not that ram can sell at high performance RAM already. if im not mistaken the highest MHz i achieve on last time is 2.5-4-4-8, 1T, 3.2v . highest than 275MHz memtest got thousand errors in test5
that time i think all RAM advanced setting i set to default or auto, just change the 1T and Max Async Latency to 7 and Read preable to 5. Didnt test CL3 in fact, i cannot realy remember.

For your information, My 2x512MB Corsair TwinX batch are 0512053-7. mean is year05 week 12 product one . Any comment on it ?

I having weird problem for my Venice... more detail refer to Venice Overclocking and Discussion Thread

Usually if my prime passed 2 days, the system is stable for more than 1 month full load. My 2x512MB Corsair TwinX PC3200 can run at 2-2-2-5 by default wor. 2.80V already can reach 255MHz (2.5-3-3-11) with a crappy nforce2 chipset. I dont think u need sucha high voltage la. btw, what motherboard r u using?
My Corsair batch is 0529083-5, dunno isit good or not, hahaha.

Wah? One month full load???
Man, you are crazy!

Actually you don't need to stress for 2 days, but you can if you wanted to. Besides, other hardware maybe in risk of getting damage if you stress your system for 2 days or worst if 1 month. And you will end up paying more electrical bills then ever before...

I usually run Windows Memtest for about 2-3 hours to check for stability and continue with some intensive benchmarking such as UT2K4 Primeval, Doom 3 demo1, CSS:VST with Prime95/SP2004 running in the background. If it passed without a hitch, I will test the stability by playing CSS with maximum bots loaded.

Also, remember to face a cooling fan towards the memory modules as TCCD/TCC5 chips tends to get pretty hot during Memtests especially test #5.

Yeah, i m damn crazy about stable o/c and uptime

My CPU already passed the 2nd anniversary. In the past 2 years I've been full loading it either with United Devices or prime95. Only able to rest at most 1 week out of 365 days. My DFI Ultra Infinity and Hynix BT-J also been stressed for 1 year, no problem so far. One of my hard disk already 3 year old, and the SATA oso 1 year already. PSU and sound card served me longest - 4 years and 5 years respectively. I think it's a matter of component. If u buy slightly expensive stuff and take care of the system well enough (dun overvolt and overheat), the components should can last quite long.

Oh well, i dont need to worry about electric bill coz staying in hostel for 4.5 years d, tat's y i nv turn off the PC at all, unless doing routine cleaning or need to carry somewhere for presentation.

btw, from my experience, if u can passed 2 days prime full load, yr windows wont gives u headache. If lucky enough , u may not need to format the system for 1 whole year, and the system won't feel laggy

my ocz EL tcc5 can do 200mhz 2-2-2-5-1T with only 2.5V

Any wrong setting here?
memtest #5 no error so far but once in window try run Prime95 will failed within 1min
How to overcome this ?

after follow some guide and suggestion from you guys,
now my TCCD able to run at 270MHz ,2.5-4-3-7, 1T, 2.7v
last time need 3.0v...

I wonder is it tighter DRAM setting is suitable for TCCD ?
I realiased one thing is that, the RAM run more hotter than when i set to 3.2v !!!

I would suggest you to find the max of your CPU and RAM first before overclocking.

Here is a complete guide to do that:

http://www.dfi-street.com/forum/showthread.php?t=20823

And I would recommend you run test 8 in memtest as well.

I saw that thread too yesterday,
in fact i have to satisfy with my board, should said cannot expect too much
coz my board is budget mobo only ..

normally i will run full test after 1hours of test#5 and #8 each.
but then i think now suitable me to find max HTT my processor can go first.

i expect too much for my RAM la .. haha

Wish me luck

As long as you can run daily application and games without any hitch, I think you're good to go even though you fail prime. You certainly did not build the system to run Prime, it's just a stability guidance program. Unless you are some perfectionist.

ahpaul82: Try to keep your CPU clock to the original speed by lowering the multi. Unless you are sure that your CPU can do 270HTT at x9 multi...

maybe u need more cpu voltage

memtest examine RAM stability, but not the motherboard and CPU. Try 2 instances of prime should do the job well. If u don't wanna run 2 days, 6 hours is more than enough for daily usage.

is kvr with samsung tccd has the same OC potential? 512mb vs 1gb, 512mb will be better in OC?

i don't think there's any KVR with TCCD chips because TCCD are considered premium chips... not value chips (expensive production cost)

hmm...my sandy wit tccd oredi run 3day non stop run BT.
running at 2.5-4-3-6 1t@3.0v@321*9

soulfly:- how abt ur pc uptimes wen running 300fsb, u got blow any fan to the ram? cos my ram d@mn hot, 42'c
this normal or too hot for tccd??

thanks soulfly, how bout samsung tccc? izzit a good 1?

TCCC, i'm not so sure whether it's quite good or not. but the best one i've seen is only around 250mhz, but most of them can do only around 230-240 with loose timings.

you can find TCCC in some KVR and Apacer Value

guys, my situation is:

able to do 2.5-4-4-8 @ 275 w/ 1t, no error in memtest.

but w/ same timing, can't do 300 w/ 1t(millions of errors), 2t gimme bout 150 errors in each loop in test 5.

bios everything is set to auto (mem. config), i've tried soulfly's setting but it gimme instant restart.

my setup:
as in siggy, my fc is of tccd chip w/ 2.8~2.9 vdimm.

any tips from u guys? kakaroto's tccd mem guide (from xtremesystem) doesn't work for me... i know, he's usin ff or le series, while mine is juz fc...

is it becoz of mobo limitation? or sumthg wrong w/ my ram (and setting)?

thx for any input guys...

ah_khoo..... are you the same one in DFI-Street?
Well, the problem is with the mobo. I was never able to do 1T at 300MHz with 2x512MB kit on the nF3 Ultra-D.

yup bro... thx for d info...

well, guess i gotta aim for higher htt then...

to match d bandwidth 275 @ 1t, i think i need to do 31x-320 @ 2t... now only i know how big d gap is between 1t and 2t...

edited: not sure whether this fc can do 31xhtt or not...

This post has been edited by ah_khoo: Sep 15 2005, 03:58 PM

2T or 1T? i'm interested at getting 1 stick of 1gb kvr tccc from newguy if it's able to run at 1T, my mobo sux at 2 stick of ram

1T of course

anyway... this thread is meant for DDR600 TCCD and TCC5only... so let's back to the topic

using patriot over here, but not sure whether it's xblk or not,
got 270 2.5-4-3-5 on my ai7,
tested at neo2 to be bootable at 300 3-4-4,
around 280 or so 2.5-4-4..

forgot all the figures already since i havnt been playing around with my hardware for quite some time..

i'm doin 311htt @ 2t w/ 2.9v (bios set), but in bios value displayed is 2.96V with my fc. 300htt gime no error nemore. again, everything is auto(for mem. config), thou there're some errors w/ 311htt, but i think it'll be fine after few days of burn in...

i'm findin d max freq of my ram 1st, hopefully it can reach 322htt w/o error then i'll ask u guys for help w/ d settings in mem config coz i've no idea to deal with it (too many options)...

hope u guys doin well too...

edited:2.5-4-4-8 for all htt...

ah_khoo

it's better to find your limit by running at 1T

.....coz 2T is gay on DFI

the extra memory option is not that hard. first you try to get some settings that has been regularly used by everybody, but make sure the type of mobo and ram that is used is similar to yours. for example u might want to find a setting that is similar to somebody that is using lanparty nf3 ultra-d with TCCD. from there u just test 1 by 1 on the options that different ppl use different values. for the options that most ppl using the same value, just leave it that way.

that's the method that i used to reduce my RAM voltage from 3.2V memtest stable to 2.9V memtest stable, on my TCC5 of course.

ah_khoo: Better don't burnin your TCCD. Burning in TCCD will screw up the RAM.

I'll say try from 2.7V to 2.8V... 2.9V max on that mobo because it overvolts.

My TCCD can do 300MHz at 2T with no memtest errors but BSODs in Windows. Previously no BSOD or whatsover in Windows at 300Mhz and above.

My previous results doing 323Mhz at 3-4-4-8-2T on 2x512MB TCCD on DFI LP UT NF3 Ultra-D:


But sadly, I'm not able to do that anymore with my Winne. Changed to Venice and hoped the better mem controller can solve my problem but it did not help me either. Maybe I screwed the RAM by trying to run it at 3.0V
OR maybe the mobo is screwed!

i do not know whteher is this the right thread to ask this or not, but i wud wana get a gig of hi perf rams, i am not sure which type to choose...the GSkill FF or Mushkin XP4000...

I kno GSkill can reach more than DDR600...wif timings bout 2337, but d mushkins instead, can most prob reach bout DDR540++ wif 2225...kinda torned in between these two at the moment...

so wud anybody mind advicing me?

It depends whether your processor can cope with up to 300mhz DDR or not, unless you can run the DDR with ratio higher than the FSB, which is not possible.

no need larr. its nice edi. dont push to hard, but if u got alot $$$ then up to u. if i were u, better change the processor & get the higher multiplier wan

IMO

juz test my gskill fc, found tat it can't pass memtest #5 @ latency 2-2-2-5.

i'm using 2.73v..

if you can't pass the actual rating, send it for RMA

using default timing, 2.5-4-4-7 is okay...
so, warranty claiming, dunno accept or not...

buy geil one tccd fsb 220 also can get cl222 ddr 280 cl2.5336 ddr300 2.5447

how about your vini3200 still oc oc ka fry 3g aledy

my winnie hit 260 lastime...

and venice, nice, going 270 @ air cooling, i'm trying to lower the voltage.
hope to archieve 280 or more.

i wish i can run 1T for htt > 300 too, but seems like it's quite impossible. i've asked some users of 2*512 tccd/5, they're havin d same problem too. i can safely say it's becoz of chipset limitation on nf3 ultra.


i hope i didn't screwed up d ram... coz it cos me bout d $$ i've spent on my mobo + processor...

so far 300htt @ 2.5-4-4-8 w/ 2.96V memtest error free but can't complete super pi 32M... any idea guy?

my venice confirm no problem runnin 300htt, seems like this ram dun wanna coorperate...

i face same problem...
now trying to rematch it for stability...

should get more stick...

mayb kvmcom's geil tccd better perform?
he own nice stuff

I'd say screw Memtest cos its not reliable at all. Run Windows Memtest for stability check instead.

Well, from what I have tested, my previous DFI LP UT nF3 Ultra-D had issues with 2x512MB TCCDs doing 300MHz at 1T, but no issues with 2x256MB at 300MHz - 1T.
Thinking that nF3 limits 1T at 300MHz, I tested the same 2x512MB TCCD on Abit AN8-SLI (nF4) and it gets worst. I'm not sure if the memory is screwed coz now it wont even do 200MHz at 1T on the nF4 setup. It will pass Memtest1.6 at 290Mhz 1T without any errors but BSODs when booting into Windows.

I'm running 2x256MB TCCD at 300MHz - 1T on the AN8-SLI now and with just 2.7VDimm, it passed OCCT and running Windows Memtest at the moment. Looks like this board is also having a tough time eating 2x512MB TCCD sticks

memtest86 is not unreliable. it's meant to test purely on ram.

you can pass memtest86 but fail to get into windows because other factor counts... like cpu stability and other components as well

tccd won't do 200htt @ 1T, sounds weird... is there a possible dat it was caused by mobo?

i wished i can have those 2*256 tccd module, juz wanna push d cpu + ram to d max...

i started to doubt d reliability of memtest coz my venice run fine @ 2.7 with my bh-5 (133 divider, error free), but w/ my fc, no matter how high d vdimm (1:1, error free) still it failed in super pi 32M...

gonna dig out d windows based memtest ledi. update u guys if i find sumthg new...

thx for all d input guys, esp raymond n master soulfly...

i dunno, but mine can't do 2-2-2-5 @ 200mhz...

is okay using default spd, now 4 stick go for 250mhz, wif the most relax setting

Yes, there are some TCCD that cannot do 2-2-2-x 200mhz @1T, because TCCD is actually binned to run at 500mhz

same case with TCC5, which is actually binned at 466mhz, but results showing that more/most TCC5 can do 2-2-2-x 200mhz compare to TCCD

i'm doing a simple test...
and found out tat, tccd perform well @ 2-3-3-X
and may go 220 for tat speed...

now running 250...
still in testing progress...

my fc onli like 2.5-4-4-x, even 2.5-4-3-x will give thousands of errors, regardless 1t or 2t for htt > 275, never try lower thou...

i've tried d windows based memtest juznow, 2.5-4-4-8 @ 300HTT (2T) seems fine, but i need to feed 2.96V for d ram, any lower will give some errors.

so d method i've found to burn in ram is:

1. run dos based memtest til' nomore error in all test.

2. run sandra burn in wizard (mem. bandwidth) around 100-200 pass

3. test stability w/ windows based memtest.

how bout u guys?

1000 round of test5 for memtest...
then only 3 days full test for memory

I run memtest with test #5 until it's fully stable without errors for hours.

Then I start playing with vcore, vchipset and vagp if it's not stable in windows. The method works quite well.
