Just simply try it, 3.3 unstabil. playing NFSMW.. hang. Wanna try but 2molo got exam. what the setting to OC these ram?

3.3ghz is your processor, your rams depend on the FSB and divider (should be 1:1 if u didnt change it)
just use around 2.9v, should be enough

try changing timings to either 2.5-3-3-7 or 3-4-4-8 and see which it does best with

i have problem set it to 2.5-3-3-7 or 2-3-3-7. Now matter wad the CAS always is 3. Still waiting the reply from RAMGUY acording this problem. Cause it should run at either 2 or 2.5.

Just now using 3-3-3-8 at 227x15 = 3.4Ghz divider is 1:1. prime it no problem and play few round of NFSMW. So what IC do u think? Mosels or Promos?

Thank for advice!

Hi,

I had a pair of twinx xms3200 c2p 512M and was running 250fsb on my p4 2.4c at 3.0ghz for about a year at 2.3.3.6 using the 5:4 divisor. I am using an 865pe msi neo2 mobo.

I recently replaced them with the twinx xms3200 c2p 1024M but have been unable to maintain the same fsb or timing. The system becomes unstable and memtest registers errors. Help anyone? I want to maintain the 250fsb but have so far failed to do so. If anyone knows what the settings are, please let me know. Thanks.

First of all, which revision is your rams? It's written on the sticker. once the revision is known, we can guide u from there.

Anyways, if your on intel, it's best to run 1:1 with slack timings. [relatively speaking when you don have the rams that will do tight timings]

i'm using XMS3200 pro Rev5.2.. y i can't reach 271fsb ??

Maybe because you're on Intel?

Intel memory controller is not as good as AMD's.

First of all, is ur CPU capable of doin 13x271fsb stable? If it's guaranteed stable on that speed, mem tweaking is needed

ya 13* .. but my best try is 13*250 only.. donno what happen..

so you've already tested your 2.6C to be stable at 3.5ghz?

wow...that tccd of pcmodding is damn gr8...doing that fsb at 2.7v only...a real gem...mine can do 310@2.5448 but at 3.0vdim
i know some may think it is suicidal, but mine is tccx. is it the same, i mean in terms of voltage limitation. well, i'm still pushing it higher. hope to get 315. will post mine later.

xms3200 revision 5.2 1024

Thank you in advance.

most probably Promos -5 Rev. A but can also be Mosel Vitelic.

u can check here http://www.houseofhelp.com/v2/showthread.php?t=44365

nope just 3.25 only.. 13x250=3250

that's what kucing was trying to say earlier
if you set your rams to 270, your proc will be running at 270X13 = 3.5ghz
so it might be that your proc cant do 3.5ghz, so it wont run 270fsb
your proc's fault, not the rams

so have any idea to make there proc can run at 3.5ghz le?

U've got to ensure that the CPU speed isn't the limiting factor. Obviously, if the CPU is the ceiling wall, the RAMS can't be pushed.

YEs, there's a solution. Get a Dry ICe, LN2, Prommy Setup

wah no need gua?? // my temp when oc to 3.25 full load only 51~52c only.. still can go up right? did i need add more power? how many i can add ah?

Hi,

I have a pair of xms4000v3.1 256mb, Which is the best timing i can get? Btw, i have P4 2.8ghz prescott and i can't overclock it to higher fsb. When i did it will auto reboot while running prime95 eventhough overclock at 2.9Ghz. What seems to be the problem? Need help

heh? SuperPI 32MB only ar? It's more like testing the CPU stability rather than RAM.

xyoshix: try slightly higher vchip. btw, wat's yr PSU?
