Here's the deal:
At x39 and anything past that:
1. +.040 and so on fails automatically whether i make it far enough to turn on prime95 or not.
2. Less than +0.040 I see it doesn't fail until I run prime95.
3. Even if I put my turbo voltage to +0.100, the voltage in CPU-Z reports 1.152v before bsoding.
4. All of my settings are by the guidelines of this guide.
5. When I use the auto overclocking utility provided, none of them survive prime95.
6. I've reset the CMOS and still get the same issue (Taken out battery and everything)
7. I have never in my life seen cpu-z report 1.2v and up
edit: I meant 0.040

I'm assuming the rig runs fine with all stock settings - right? if yes,
Okay, let's try something. set the voltage settings to offset +0.020V (20mV) and turbo to auto. multiplier to 38. Find a clean USB key and place it in a usb slot then post to bios (not to windows). hit F12 on the bios page "Monitor" or what ever it is called in your bios. We need to see the bios vcore and dram V settings (which are at the XMP setting - yes?). Also F12 the page with cpu pll and other principal parameters.

if this fails, we'll go to a fixed mode OC.

With your settings, It failed within 1 minute of prime95. The vcore on CPU-Z showed max of 1.136v.
Also, I don't have a fixed option in overclocking in my bios. It is updated to the latest version.

not sure what you meant by no fixed option, but the fixed option can be found on the same button as the offset mode. It can be turned to fixed iirc on my asrock ext.

Asrock z77 pro3 doesn't have a fixed voltage setting. You are confusing your board with mine.

ahhh i just checked my bad, indeed pro3 doesnt have a fixed voltage setting.

Did you try with 50%/75% LLC? From my brief googling it seems the board is using lower phase counts which "might" be throttling your OC that I'm not too sure.
post #6916 of 9543
I've tried all the LLC settings and 100% seems to be the most stable.
Also, I've noticed something extremely strange.
When using +0.005v offset, I bsod when running prime95 for <1min. When using -0.045v offset, it runs fine. ***!! Since when does undervolting = more stability???? I'm going to keep playing with this and see what I get.

Update:
Seems my motherboard is some weird mutated anomaly. With a -0.045v offset, I am at 4.2ghz stable. My computer wouldn't even boot with a +0.005v and higher offset. Any scientists in here willing to explain this magical phenomenon?

Actually - that's pretty common - many guys had the same problem and posted to this board. That's why I asked to see the bios vcore. cpuZ is not helping here. So basically the chip was overvolting and doing a 124 bsod. Another thing, set your ramV manually to the jedec or xmp spec for the frequency you have them at, not auto. While working negative offset try keeping additional turbo on auto. LLC to a mid level value, do not defeat vdroop, it's a good thing.

Bios is not reading the VID line correctly.

The only way to really know what vcore your pumping is with a DMM at this point. But just keep an eye on your temperatures and set up WHEA alert (search the forums for "Wheaville") it really helps in nailing down stability. Check event viewer for Kernel-WHEA.

Thanks... Again! (followed this 11 or 12 months ago and need to do it again)
I had no problems with holding 5 GHz stable. But I just installed a new SSD drive for the OS and decided to do a full, clean installation of EVERYTHING. I've installed almost all my ‘regular’ software on a 1TB Seagate Barracuda and I'm installing ONLY FSX related programs on a 2nd installed Seagate Barracuda, (also 1TB). But I updated my UEFI from the version I had, (2.0), BEFORE I had backed up my saved OC Profiles.

So the new UEFI version won't read the "OC DNA" profiles I had saved on a flash drive. So, the last two days, I've been searching for this very article because it's pretty much what I followed 11 months ago before I installed the SSD and got great results, (I'm water cooled).

I installed that SSD and most of my programs two weeks ago and now, (man, it’s fast!), and I need to get the system ready to run at my old OC speeds. Then I'll begin the long, tedious, process of installing FSX and 140GB of High-Res scenery and aircraft add-ons.

I'm glad you hadn't removed this guide even though there are a few spots where the info has apparently been blocked, (probably for updated reasons). But I have what I need and I'm off to do the deal!
Thanks again!thumb.gif
post #6919 of 9543
Followed this guide with an I5-3570K using aftermarket coolers, 8 Gigs of Corsair RAM, GTX660Ti, and a Z68 ASrock Gen 3 mobo. I got lower performance, so I decided to go back to default settings, but the performance is still lower than usual. The temp didn't go over 74C and I changed the "Additional Turbo Voltage" from auto to +0.004v and the offset to +0.005v during the OC, but changed it back to auto afterwards. This is a big difference in performance by the way, so it's not just placebo.

EDIT: Fixed it, it wasn't because of the overclock! I had a virus which I got when I installed some software the day after the overclock, hence I didn't notice the fist night.

Okay so I have replaced my faulty memory and have a new GTX 770 Graphics Card. Time to start overclocking the CPU again.

Aiming to take the CPU to 4.5 however I'm worried about cooling, with the current setup I only have one extract fan for the system and no intake.
The motherboard can only control two fans, so one is being used for the CPU pump. Should I invest in a fan controller and install more fans before taking the CPU to 4.5?

Thanks Everyone.
