btw at stock this crap processor need 1.201v, i am crying in advance... will test more
1.25v x45 booted into windows but crashed on aida fpu test

Ah, 5800 probably was the tested max validation with ln2.
My chip is pretty average, but a little bit better than 1.2V for stock biggrin.gif 5800Mhz max for 4c/8t full load, 6ghz for validation.
I want a better one but failed so badly binning ivy I don't want to buy up retail chips again with haswell...

i am not going even to try more to find better chip i am tired already. i will wait till skylake till then i will focus on new case/cooling/gpus/peripherals

Can't remember where I read that, but it was posted here by someone who would know, like unclewebb.

this is still happening in Blend test's large FFT potion. In Small FFT, AIDA64, Realbench or H.264 encoding, this doesn't happen. I even downloaded Prime95 back again. I just hope this will not incorrectly diagnose the CPU as stable when it is not.

SmallFFT:

LargeFFT:

before this, I ran the following tests.
1. AIDA64 for 2.5hrs
2. H.264 single pass encoding in Handbrake for 2.5Hrs
3. Crysis 3 multiplayer for about 2Hrs (I use medium graphics, so the CPU comes more into play)
4. Asus Realbench for 7Hrs overnight

Now Prime95 has been running for 1Hr.

i guess this is stable enough and i'm gonna stick to this core OC and tune the memory and cache.

Good luck! P95 blend is some hard stuff!!

The pump was probably cavitating from spinning too fast and this was causing the noise and reducing flow.

Any clue as to why the clocks dip in the large FFT potion of blend test? I don't think that's normal.

No idea man... I start my monitoring software right after I start the test and my minimum is the same as maximum clock through the test. redface.gif

Edit: maybe it's the fact you are not running default base clock? I don't know...

oh noes. BSOD 0x124 after just before 2hrs. frown.gif
funny thing is, it got the BSOD as soon as my wife came near the PC. biggrin.gif

now what? raise the Vcore by 0.005V?

Curious about my high 1.25v temps, I wanted to check my stock temps in Intel burn test. It shot up to 75*C on STOCK. did I mount my h100i wrong?
