try up the pll a notch, it helps overclocking stability. try keeping it under 1.88 though
Ok i upped cpu pll to 1.84

I'm at
cpu multi 21
bclk 180
vcore 1.28
qpi/vtt 1.33
dram 1.6

testing in ibt now.. usually the error occurs between the first and third pass.

edit it still is happening

Could be software, try this....
Now open up an elevated Command Prompt (run as administrator) and type in sfc /scannow, hit enter, and allow it to see if it can fix anything in Windows. Once that is done open up another elevated Command Prompt and type in chkdsk /r, hit enter, and then reply with a Y when prompted that it can't run now, do you want to run it the next time you reboot (or something to that effect), then restart the system to allow it to run. Depending on how many errors it finds and the size of your OS partition this could take anywhere from 20 minutes to a couple of hours to complete.

Okay im doing what you said h969. I recently reinstalled windows though about 3 days ago.

Anyways this time on my last linX test I was able to get to 14 passes out of 20, before it was only 3 and nothing has changed from my last post

the harddrive had no errors it said it was clean.

scannow showed some windows errors that could not be fixed, but the log list is huge from previous days of error logs from crashing and stuff.

Not sure what to do..literally yesterday i had a 3.8ghz overclock that was stable for 25 ibt tests and 10 hours of prime95. I reverted the settings then tried to go back to similar settings and IBT and linX consider the system unstable but it doesn't crash.

I reinstalled windows 3 days ago.

I saw in a previous post your Dram Voltage is 1.6v
Doesn't that Corsair take 1.65v???

It looks like your almost there.

If your memory is at 1.6v, raise it to 1.65v
& raise your vcore to 1.285v to 1.29v

hyper threading and turbo mode are off, as well as the other power saving stuff

168x23
vcore - 1.3
dram voltage - 1.66
qpi-1.31

i set the memory multiplier to 8 also and have not touched the timing.

Not sure what to do.. I had a Stable OC at 3.8ghz that could pass 50 IBT passes but now I can't.. i also don't really remember my previous settings
Why did you lower vcore when you lowered bclk?

Critical error in LinX but no bsod - have you tried reseating ram? Just thinking you may have disturbed it.
Does it pass small fft in Prime05 but not blend?

My settings, in case they're useful:

I'll try reseating the ram now.

When running IBT/linx the errors seem to come after the second pass, once my linx test got to 14 out of 25 but still found something wrong. You think it could be a memory issue?

I've run blend for over 30 minutes with nothing wrong, I was testing with prime95 on my current settings before I read this.
post #19 of 55
Have you tried taking off your oc and "Loading defaults" to see if you can run linX without an error? That is where I would start. If you pass w/out errors we can assume it's not hardware related. Then you can proceed with everyones suggestions and work on getting your voltages right. Just saying...

If you can run blend, probably not ram.

Does it pass other stress tests? Is it only LinX/IBT that it fails?
