Pcmoddingmy's test result @ page2 #22

Test bed:
Amd A64 3200+
TR XP-90C
DFI Sli-DR Expert
200GB WD SATA II
Acbel 500W PSU

xms3513pro1gb.JPG

Testing:
The meaning of OC here is really on OCing the ram,
over the default rated speed.
so, 1st target will be over 3500.

and that is the result.
this is 250 3-3-2-5 @ 2.7v


@260, with such a rate, 3d stable, prime stable, superPi 32M stable.


@265, only able to get sandramark.
the pc freeze while i play CS.


take a look at the voltage,
since my 0516FPAW does not give me impressive result,
for temporarily, i'll stop here @260.

will go for another try, when getting gsan's venice.

Weird reporting:
this ram does not like much on high voltage.
infact, it can do pretty well on extreme low voltage.

I dunno how to describe...
Let's take a look at the picture...
see the voltage of ram urself, no cheating...

where's the picture?

cannot upload, juz tested, facing weird problems on my streamyx.
please wait.
lepas aku siap dengan tmnet, i'll make the actual photo available.

izzit 2.26VDimm?if that so...mine too, i think it just ur sensor read it incorrectly...mine shown 3.34VDimm oso, but using other monitoring program, acceptable voltage ady...

i manually set on bios, the lowest voltage ever, 2.29v

wokaloh...y u set it to lowest vdimm?can even boot up huh...any reason to decrease the voltage?

Full story:

this pair of ram is the latest DDR produce by corsair.
item is twinx 2048 3500LL pro.
and i hv confirm from the houseofhelp(ramguy) is infineon rev c.

so i juz started the adventure of OC...
1st attempt hitting 250 on 3-3-2-5, using 2.8v...
i juz ran for only 14 minutes prime, failed...
so no choice, down to 9/10 divider, so is running 227.
then start process of priming...

of course now when i free, i started attempt again...
manatau, memtest86+ also getting tons of error of test #5.

then cannot, try by add up voltage...
wah! more error occured.
for 250mhz, i hv lowering the voltage untill 2.4v, and it gave the less error.

i never dare to try more than 2.87v.
since knew that 2.84v giving more error.
then conclusion i can made is, this ram run on low voltage.
very low!

Erkk.. weird but if giving more voltage doesnt help either than u have to play with your setup and find the best configuration. And you can google to find results of infineon rev c, how they oc and their voltage requirements.

low voltage no gd meh? i tot the lower the better?

i got the same experience..
i'd test be-5 and ce-5 b4.. both of them perform better with low VDimm.. increase the VDimm will just give error in memtest or prime95 when achieving higher fsb..

too bad my a8n sli premium cant do lower than 2.6vdimm
have to wait coming sli-dr lor...

only expert and the crossfire support lowest to 2.29v.

alamak...SLI-DR cannot aaa? again
but izzit necessary to set to lower vdimm?i've been told oso, samsung chips love low vdimm, izzit true?how low?

around 2.7-2.8v. not as low as 2.2v...

dunno...

another testing now...
250@ 2.7v.

16 idle cycle limit
Async/RP 8/6
Drive & data strength set to 7/4

and, it works fine under priming, for 2 hours, still testing.
lookslike i hv to do a full testing for every possible combinations...

later when 3d stable, prime stable, pi stable, i'll continue raising up.
but my proc limit my speed, it is hard 4 me now to raise the clock more than 250.

expert ? It takes me weeks to finally find the best combination of Drive Strength and Tref. Set your Drive and Data Strength to AUTO. PLay with your Tref first. I find 4708 to be the best for my mushkin BH5. Then i slowly tweaked it and found level 6 for drive strength and level 1 for data strength.

dunno what is happen to my streamyx, can't upload any photo.

damn.....2.26v......

If u've gone through XS, yes, many users had tested them with lower volts, especially on infineons CE/BE and it actually overclocks well. However, some reported otherwise

^^
their result is very varies.. depends on the production weeks i guess?..

test updated

Hey Westley, mind if I post my results in your thread?

Anyways, here's my latest overclocking result with Corsair 2GB 3500LLPRO v1.2

DFI LP UT RDX200 CF-DR - AMD Opteron 144 (watercooled) - SilverStone ST60F 600W - GeForce 6800GS

250HTT - 250MHz - 2.5-3-2-5-1T @ 2.4V - 25hours Prime Stable - 3D Stable


These 3500LLPRO v.12 modules surely loves undervoltin'!
If I gave it 2.7V, it will complete Super PI 32M and Prime for about 8hours before going into a blank screen. Need to restart it this happens...

Memtested for 1hour at 260MHz with those timings just now but failed to boot into Windows. Currently trying to get it stable at 255MHz at 2.5-3-3-7-1T.. still 2.4V...Already passed 2hour Priming in blend test.

welcome

250mhz does not need any loose timing,
i still keep trc=7 trfc=14
Dram drive strength=7
data strength=4
not to mention the idle cycle limit can still do 16

Currently my DRAM DS = 2 and Data S = 1...If I set it to 7/4, it will be shown as "weak" in A64Tweaker or A64Info.
Not very sure about trc=7 and trfc=14 though...will try later..

Update: Can only Prime for about 5hours at 255MHz with 2.5-3-3-7, not very stable.. maybe need to set to 2.45V.

Thanks for the tip..

pcmoddingmy, how is the different for cl2.5 and cl3, for ur ram @ 250mhz?
well, mine juz raise not more than 20 mark for sandra.


Attached thumbnail(s)

Westly, the difference between CL2.5 and CL3 at 250MHz with my setup was 50 MB/s.
Btw, my score was lower because my CPU has a 9x multiplier.

Nowadays everyone play DDR2 RAM,
but i still playing DDR1 RAM

Here is my Initial Result,





I feel quite surprise it able to go into window and bench SuperPI 8MB at CL2.5-3-2-6,1T, 2.6V at 260MHz.

more to come

Micron -5B chips isn't it?

Mine is CMX1024-3500LLPRO XMS3502v1.3,
0605217-1.

so should be Infineon CE-5 chipset.
Source HERE

11hours Dual New Prime :



This pair is a lot better than my OCZ PC4000 Gold GX XTC 2GB (Samusng UCCC),
no need tweak too much, put in set some certain setting, thats it, rock stable.
didnt give me any error .

Change to CL3-3-2-6,1T,2.6v at 270MHz can passed SuperPI 32M too~
it seem can go higher than 270MHz...

In fact, i didnt test it with memtest

Edit :
changed the screenshot with new Prime v25.1,
and the DDS changed to Level1 and voltage pump to 2.7v.

Should be new record ?
