Ok so for 46x i raised turbo to +.105V.... it doesnt get WHEA errors until 30+mins into the test.


But to be realistic if im not gonna be loading my CPU as much as prime im prob ok right?




I also got a new PSU last night but havent tested again. IDK if it would make a difference.

Nice work!, thumb.gif
If you are managing the temperature at +105mV, you'll likely loose that nasty whea with 110mV. It's best to eliminate whea since thay basically kill the efficiency of the chip as it re does a stack because the checksum failed. A PSU should not matter inless the first one was faulty or underpowered.

crosspost from the Asrock Z77 OC Formula thread:

need some help here.

up to 4.3ghz with Nick's profiles run stable, no issue.

now, from 4.4ghz on, with Nick's profiles or OCing from scratch, my memories seem to get unstable.

at 4.4 nick's profile i can boot to win7 without a problem, but prime95, IBT and 3dmark11 all crash during stress. i don't really get any BSODs but the stress apps and also random programs crash. so, i figure it's definetely memory instability.

i've tried increasing and decreasing dram voltage, increasing vtt, increasing vccsa, increasing/decreasing vcore, but none of it seems to help stabilize the mems.

i don't think the mems are the problem cause i've had them on my previous system (2500k on an asrock p67 extreme6 running stable at 4.8) and also tested them with memtest at that system with no errors. i'll be running memtest this night on this rig for good measure.

so, any ideas how to get this stable? i mean, come on, it's just 4.4! can it be my cpu or mobo?

thanks in advance.

oh, it's the "black box" rig in my sig. mems are on XMP config, which is stock.

edit: memtest found no errors after running for over 7h.

I agree it doesn't sound too likely to be the memory after it has been running fine all the time.
As another test, you could increase the Vcore to the maximum you're comfortable with and see if it runs fine then.


@SilverApples
You don't necessarily need to spend 100 bucks for a decent cooler, if you don't intend to do higher overclocks. There are quite a few top notch air coolers available that will do the job just fine. Plus they provide some indirect cooling to the VRM units as well, which completely lacks when using (non custom) water cooling.


Regarding WHEA errors, I've found that running Prime with 864k is very reliable in finding them pretty quickly.

Yeah, this has been driving me nuts on the same board and same chip. you have bios 2.00 yes? What speed DdR3?
For clocks up to 46x be sure to enter 600-1000 in long and short duration power, and 1second. Everything else on auto. 46x should come in at around 5mV offset, 50mV turbo. Manually enter vdram at one notch below rated dram v. See if this helps. I'll be back on line in a few hours (this evening).

Maybe we can figure this out.

Btw- i got 47 going on this OCF tho mainly an "edisioian" experience. 40 min into p95 with 8192 mb ram. Load vcore is 1.256 (1.245 by DMM)

yes, bios 2.0
my ram is Corsair Vengeance LP 1600mhz at 1.35v

hmm i'll try those long and short duration plus the 1s.

i've been doing only fixed voltage, so i guess it's time to go offset or turbo and see if it changes anything.

i've already tried lowering the dram voltage, it helped to last a bit longer before crashing the stress test apps, but only for like 2 minutes and a half.

hmm i'll try those long and short duration plus the 1s.

i've been doing only fixed voltage, so i guess it's time to go offset or turbo and see if it changes anything.

i've already tried lowering the dram voltage, it helped to last a bit longer before crashing the stress test apps, but only for like 2 minutes and a half.

before changing any settings from fixed. two things have worked for me. lower the dram v as you did, raise VT1 by 1 or two notches, and lower VT2 by one notch as in the bios settings I posted earlier. it may take a little tweaking of those two parameters, but I finally got 47 stable (1hour with 12288MB ram committed). with your cooling (not delidded I presume?) controlling temperature may be the limiting factor, but a full loop like you have will help a lot.. post back with how you do.
I'll reload 47 and grab some screen shots for all pages.
I began working on 48...

Ok. Decided to get the noctua d14 cooler. Anyone know if I'll be able to reach a stable 4.5 to 4.8ghz with this cooler with acceptable temps? Also I'll be upgrading my ram, is there a certain type that's best for overclocking your cpu (not oc'ing ram) as in clock speeds like 1600, 1866, 2000 and above? I plan to to buy 2400mhz 2x8GB
