i believe, you should see it under H/W monitor section in bios. vcore is just the cpu core voltage. it changes depending on how much work its doing. Also if you download and use cpu-z program..it will report the vcore in windows. at idle it will be lower...if you put it under load...like when you run Prime95 stress test...it should go up.

Hi, I followed this guide exactly and didn't even increase the multiplier off the default (34). I saved the settings and the motherboard could no longer recognize both my Corsair Vengeance 4GB sticks. I took one out and was able to get into the Bios to revert the settings back.

Which setting could have caused this issue?

Here is my RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E16820233144. Details say it is 9-9-9-24, which is what I set it to in Bios. I also set it to 1600 instead of 1333.

Motherboard is Asrock Extreme4 Z77. CPU is 3570k.


EDIT: My problem was probably the memory voltage. The Min I could pick was 1.65, but the memory is supposed to use 1.5. I assume that is what Auto picks?

I must admit that I can barely understand some of the voltage settings. I have only done the vcore offset and Turbo Boost offset, as well as disabling the C3 and C6 states. The best I was able to manage is +0.015 vcore and +0.008 boost which kinda shot the temps to 90C in some cases. Effective voltage at load is between 1.260-1.280 V, which is substantially higher than yours.

Update: No matter what VCore offset or Turbo Boost offset I put, the max voltage I'm seeing on CPU-Z is 1.280 V for some reason. Sorry for being ignorant on this, but is this to be expected? Also, the temps are dangerously high: 90-94C on 8K FFT, which is surprisingly worse when I first ran Prime95 yesterday.

Hi guys! I registered to this forum specifically to tell you thank you so much for this guide!! It has helped me drastically considering I've never overclocked before...

I've achieved 4.5Ghz, here's a screenshot:

Now I was wondering... did I do everything right? I left Turbo Voltage to Auto and offset to +0.015... is that ok? Or do I need to change this?

By the way I have the H100 for cooling smile.gif

What priority should be use for Prime?
post #847 of 9460
hi all

i'd like your helps!

what is the highest clock speed what i can safely use with the Asrock Z75pro3 mainboard?

is something wrong when I use 4.5-4.6GHZ?

Hi All,


Long time lurker first time poster. Registered to thank the op for the very nice guide. I have a (nearly) stable overclock on an ivy bridge 3770k, mb: AsRock Z77 Extreme 6. It hasn't crashed yet and I succeeded in running P95 at 4.5Ghz for 1 hour. The only thing I am slightly worried about is my vCore, it looks quite low when compared to other people with similar gear. My vCore was mostly stable at 1.152 V but went as low as 1.144 V and as high as 1.160 V. Was just wondering if this is normal, am now going to push the envelope a little to see what I can achieve within my personal max temp range(75deg max). My cpu is cooled by the Antec Kuhler 920 btw. Mobo settings are offset of 0.005 and LLC lvl 3. The base configuration in the guide basically.

1 hour mark in prime95:
338

idle right after prime95:
338


Thanks again for the exquisite guide thumb.gif.

1 hr isn't by far long enough to make sure it's stable smile.gif either way it should be stable at quite a nice voltage regardless smile.gif did you get any WHEA errors?
