is this normal: 2600k overclock

post #1 of 21
Thread Starter 
The short of it all: I can't seem to find a voltage setting that maintains any form of stability on any decent overclock. I need help.

On my motherboard, I set my CPU voltage to 1.320v, and my multiplier to 43x. When I boot up, my voltage on CPU-Z reads "1.068V" (in fact, it reads that no matter what I set the voltage to, so I figure CPU-Z isn't reading voltage very well). Another program (the Gigabyte built-in voltage reader thing) reads 1.260v.

So I tried overclocking to 4.5GHz, and I threw in a voltage of 1.355 volts, and I was immediately unstable the moment I ran prime95.

I'm wondering... are these programs just reading the voltages wrong? Or is there a feature I need to disable to keep my voltage at what I need it at? (I've tried using that overclock guide and tried disabling the various power saving functions)

I want to see how decent of an OC I can get, then I want to drop down to something like between 4.3GHz and 4.5GHz for a 24/7 overclock, but I'm getting instability at 4.5GHz at 1.355v and I'm not sure if it's because my voltage isn't staying at 1.355v, or if it's because 1.355v isn't enough.

Right now I have everything set to AUTO and my multiplier set to 43, and I'm stable with a max temps of 49/55/58/54 on prime95. Is it best to use "AUTO" on the voltage, or to manually set it? In the BIOS, it reads "1.34v" on the left, then "AUTO" on the right... does that mean it's automatically going up to 1.34v?

I want to overclock. Lol. This sucks I can't get anything stable. And I can't accurately read my voltages real-time.

Well, I'm trying to follow some guides. I'm on the newest bios version. Just not getting anything over 4GHz stable for longer than 10 minutes.

I'm happy with 4GHz (I'll probably be running that 24/7 anyways), but I'd rather go higher to see what I can theoretically manage.

Sorry I won't be providing any help, but you got me kinda freaked out. I have the same motherboard as you and I'm now paranoid that I'll get the same kind of problems when my chip arrives. Damn humanity.

You need to update CPU-Z to 1.56.1 or 1.56.2 for it to read Sandybridge Voltage properly.

I have 1.56, not sure which one. But I downloaded it only about 4 days ago. :-(

So far I've managed to hit 4.00GHz stable, but then I turned the system on standby... I had to clear my CMOS three times, boot up... basically I had to do a bunch of stuff just to get past BIOS (let alone to get into BIOS).

The BIOS version keeps reverting to F3 after failed OC's, from F7b.

Wish there were some resource on the internet that covered these problems.

I can't be the only one to be having issues with this stuff. I follow guides 100% (I think I am), yet I run into troubles.

I'm trying the F5 bios instead and seeing what happens. I'm also reformatting since I previously was using an Asus board, and I didn't reformat since.

I'm pretty sure I've seen your post on motherboard issues elsewhere and there were lots of replies. If I'm mistaken sorry but I think not! Are you not understanding or just not searching?? The answers are out there.

#1 you can't have EVERYTHING set to AUTO or you can't OC the chip.

Please search for your model motherboard and you should find your answer!

Gigabyte boards have a bug and are showing your VTT in CPUz - Your Vcore will be what you set in BIOS. You can have a look on OCCT and i think it will show correct voltage
