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 !

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
