Faulty i7 920? - Page 2

post #11 of 25
If you can catch the bsod code that you're throwing it's a little easier to interpret what's failing. If you see a 101 that'll be cpu vcore... 124 would mean too much or too little qpi... I suspect you'll throw a 101 if your problems are in fact core related.

You don't mention temps either- it could be a temp related issue.

Then again, like the one guy suggested we could be looking at the duck when in fact it's the goose. Might have a faulty RAM module- which memtest86+ should identify. Also, running 1.65 on underclocked RAM... It's safe on stock speeds of course but not sure of what happens when you put that on RAM running so far under freq. (Can someone answer that for me? Been wondering...)


If your RAM is underclocked like that you wouldn't need to up qpi from 1.35... That's probably your ceiling for qpi-

How are you doing your OC OP? Are you just bumping up the multiplier or are you using bclock? Is your BIOS the most current for the EVGA?

Yes you can uncheck the restart automatically box and write down the code.
* Windows key + pause
* Advanced System Settings
* Start up and Recovery
Settings
* System Failure
uncheck: automatically restart

BSOD is the one that says 'Irrecoverale HW error encountered' or something similar. it seems to be the one that suggests VCore problem.

Temps on full load never cross 52 degrees (for any core). Checked using EVGA Eleet and doublechecked with realTemp.

I've manually entered all stock voltages in BIOS, set RAm at 1600 and XMP profile. Basically everything stock. Gonna run 12hr Prime95 now.

I was OC'ing by BCLK. Multiplier is locked beyond 20.

No its not

Up to 1.45 is pefectly fine if needed but that would be my limit on air

Remember QPI voltage is for ram and NB freq/uncore

Sorry, I wasn't quite clear with what I meant. Where he's at now, he wouldn't need to go beyond 1.35- but yes, thank you for clarifying that

Here are the CPU-Z screenshots with everything at stock. I reset BIOS, and didn't touch a thing.

Why is the CPU running at 133x21 and not 133x20?



With everything at stock, I'll try running P95 blend test.

And this is idle temps:

Stock vtt for a 920 is 1.2, not 1.1, it was an error made by evga with that board. That is the likely cause of your issues. Also, its 21 because of turbo.

Because thats "turbo" mode thats on all i7's. It's an option you can disable.

I'd say normally you should be able to hit 3.0ghz on stock everything. If you can't push it at all I'd guess its your ram/qpi settings. Let us know if it primes fine with default bios.

But, according to the CPU-Z screenshot, it is running at 1.2. Or am I missing something?

Everything default, it ran Prime successfully for an hour. I ran memtest overnight. Last I checked, it had completed 2 passes without any errors.
