4770k Stress testing problems!

post #1 of 12
Thread Starter 
Hi everyone,

Here is my system main specs:
Intel 4770k
Asus Maximus VI Extreme
16 GB Corsair Platinum 2400 Mhz (2x8GB) for now clocked @ 1333
2x EVGA 780ti Super clocked
4x 256 GB Plextor SSD in Raid 0
Corsair h100i

Here is the problem:
I cannot pass Prime95 28.1 (x64) small FFT, event a Stock setting!
no matter what setting I use in the bios, all workers stop @ around 2 hrs every single time!

but with Prime95 27 I pass small FFT for 24 hrs no problem! (even at 4400mhz 1.225v)

I also crash Intel Burn in test even at stock but pass Intel Extreme tuning 24 hrs no problem.

But with prime95 28.1 (or .3) with CPU at stock with temp is in the middle 70c i fail like clockwork after 2hrs. (all workers just stop)

got latest bios and drivers installed on a fresh install of windows 7 Pro (fully updated)

Why is Prime95 V27 pass Small FFT @ stock setting but not Prime95 28,1?

Can someone explain me what I am missing? (do I have a dud 4770k?)

Thank You.

What are the volts under load?

@ Stock speed it's 1.160v
@ 4400 GHZ it's 1.232v

So its crashing on all the AVX enabled tests? Do you have auto voltage at stock speed? AVX will force an additional 0.1 vcore according to intel design. If it does not get that extra juice, it may fail.

 

Bottom line, stay away from AVX unless you have some good reason to need it.

I tested a lot of 4770k

most of them jump from 1.16 to 1.28 when stress testing, but this one stay @ 1.16. Does this mean the CPU is defective?

If the BIOS is set to full manual mode the cpu voltage will likely be fixed and it will not be able to jump. Saver your overclock bios profile and Reset to BIOS defaults and see if the problem persists.

on a full bios reset with all default and ram @ 1333. with vcore to auto and the problem is still there
post #8 of 12

That is odd, could be a defect then.

 

If it were me. I would see if it could do ~4.7-4.8 at 1.35 or below. If it could, I might be tempted to keep it for a while. If it does not, I would RMA it.

Enable LLC or something at level 3-4 and see if it helps. Also you are looking at the core temp right? AVX tests heat your thing up a lot more.

Seem to work with AIDA64 (FPU stressing) witch use AVX and it's been running for hours now whiteout any problem.
