File corruption when x2 3600 OC to 2.71ghz

[CptCrunch]

So, heres the issue:

I have the following:
AMD x2 3600+ Brisbane at 1.375v
OCZ Platinum Revision DDR2 2x1gb at 2.3v at DDR400 Divider at 1-3-3-8-1T
DFI Infinity NF570-M2/G which will run at 295MHz FSB
Temp at Idle: 90F, Load:~115F

Rest of the system:
80GB Western Digital HDD SATA2
160GB Seagate 7200.9 HDD SATA2
NEC DVD/RW EIDE
Corsair 620w PSU
Evga 8800GTS

Now, at stock, everything is a-ok, windows runs fine, no issues. However, when I overclock the computer to 2.71 (285x9.5) Windows XP boots fine, Prime95 is stable for hours on end. However it appears that there is issues opening some files, creating/restoring a hard drive image, installing some games (bf2142 i.e.).

For instance, BF2142 will refuse to install the update when OC'd, but is fine not OC'd. WoW is stable at stock, but at 2.71Ghz it will, at times, say the common.mpq file is corrupt - or in the instance the other day - state that the entire game directory is corrupt. Windows Vista also refuses to startup when OC'd, will freeze about 5 seconds into the boot process. When creating a hard drive image, if the image was created while OC'd, the image will be corrupt regarding of the speed of the processor during the restore. When the image was created at stock, will re-image at stock fine, but once the computer is OC'd and the image is accessed, it is now corrupt.

Now i'm not quite sure whats going on, some application errors (IE not launching, WoW, BF2142 update), no boot for Vista, hard drive images are corrupted when OC'd, yet the system is stable for prime95 and during general computer usage.

Any suggestions would be appreciated

Did you change the HT multiplier to make sure your overall HT speed is still within spec? For example HT multiplier = 5 @FSB 200, your overall HT is 1000. Now you raise your FSB to ~300, you probably need to lower your HT multiplier to 3 or 4. to make HT close to 1000.

Rchiu: Yes, forgot that detail, HTT is set to 3x, so approximately 855

And also raise the voltage. Prime95 is cra* at testing stability. I had my cpu prime stable for hours, but in games and programs the computer just used to reset. I always use dual Super PI for stability, and if it passes I throw real life situations in it, like games and programs. And sometimes it happens that the cpu is stable in everything except one single game, or one single program...

1-3-3-8

Is that right? It should be 2.5-3-3-8 at least, I'd think

 

[CptCrunch]

error8: I will try super pi and test tonight for stability

amdzen: thats what I thought, all settings are set to auto, and at the divider set, the mobo picked those timings

In my experience corruption is almost always caused by unstable ram. And yes your ram timings look to be the problem, no DDR2 that I'm aware of can do 1-3-3-8, and your ram volts look too high. I would set it manually to 3-3-3-8 2.1v then run memtest to check

*edit*

In taking a further look I am totally confused, are you running DDR400 or DDRII???.
If it's OCZ platinum rev2 DDR400, then it should run 2-2-2-5 at 2.75v

And you really shouldn't use the .5 cpu multi's on X2's or A64 it produces misleading results because AMD cpu's don't actually have or support .5 multis. You system is really running
271x10 and your ram is running slower than you think it is, and thats probably whats causing it to set timings to 1-3-3-8

He's running DDR2 ram at DDR400 mem speeds, but I am wondering what his ram is rated at as well. Is it DDR2 800,667,533 or 400? and what is the actual mem speed> NOT CPU/ FSB in MHz? is it 290? same as FSB?

If it is PC5300 DDR2 667MHz mem, then it may not be stable with 1T@290MHz actual mem speed (NOT CPU/FSB speed of 290MHz) <as an example. Confusing with all the dividers possible nowadays.

What does CPU-z list everything at CptCrunch?

For instance, I run my 3600+ X2 with my Gigabyte M690g-S3H motherboard bios settings of:
multi: 9.5
Mem divider: DDR533
HT divider:800
FSB:274MHz
CPU:1.325v
mem:1.85v

All for a rated speed of 2.6gig and some change. My HT speed is 1040MHz or something. And my mem is running 325MHz or so with the DDR533 mem divider. I'm surprised your mem has not fried with 2.3v which is pretty high for DDR2 is it not?

You are obviously not stable and it may be a PSU problem because although you may be stable in CPU and memory benchmarks you are not running a stressful 3D app at the same time with any of those apps. BF2412 is a very stressfull 3d app on top of CPU and being a mem hog and it is not working when a 3d app is run in the mix.

Sorry on the ram confusion guys, was at work and mis-typed.

My ram timings are: 3-3-3-8-1T as noted here: http://valid.x86-secret.com/show_oc.php?id=224455

Memory Divider of DDR400
Memory Volts are 2.3V
HT is running at 871.9MHz
FSB is 285MHz

The ram is rated for 1.9v-2.1v +- 5%, currently at 2.3v, but the only reason why I'm running it at that high of a voltage is because it will not reach 285MHz FSB without it. This is the OCZ Model number: OCZ2P800R22GK

I have been thinking PSU, as a few days after I received my new 620w Corsair PSU my 500gb hard drive suddenly died. I have no problem having looser timings (not 2T if I can help it) but at DDR400 the settings above are what the motherboard set. And yes, I am not too crazy about the voltage, even though they are within spec, I dont really like having it set that high. Which is why I am currently not OC'd.

I was not aware of the .5 multiplier issues with the A64 chipset. Might try this weekend to re-overclock this guy for a 9.0 Multiplier and less volts.

Drop the memory divider to DDR333, if the CPU will go higher. CPU speed is better than ramspeed
