Voltage, Gigabyte Board and CPU-Z

post #1 of 6
Thread Starter 
So I've got a pretty damn stable 4.8 Ghz overclock on my 2600K with reasonable voltages and maximum temperatures. I have a few questions however:
My voltage is set for 1.39 in the BIOs and as you can see from the screen shot, goes up to 1.43 under load.
  • Is this voltage considered cutting it to close in terms of what I should be running for a 24/7 overclock or should I be fine? The temperature is fine, whereas Intel reccomends not to go over 72 and I don't.
  • I've seen this with another Gigabyte board that someone OC'd with, how come CPU-Z is not reporting my set voltage of 1.39? Obviously it's not running at 1.056V. Is there something in the BIOs that is throwing it off?
  • And not so related if anyone cares to chime in: When I enable XMP on my memory my whole stableness of my overclock gets unstable? Should I be fiddling around with QPI/VTT at this point? Any suggestions to solve this? I'm new to sandybridge over clocking but not OC'ing in general.
Thanks!

Well, there's the whole 'vdrop and vdroop and LLC and offset' discussion, which is novel length. You'll find it in the mobo's and cpu's forums without looking too hard.

At idle, it probably *IS* running at 1.056, and on a reduced 1600ish clock speed. By design. Can be disabled if need be, can cause crashing if v goes too low at idle. Oh, I just looked at the picture - Gigabyte has some issues with CPUz, or vice versa - their onboard monitors are different somehow. Trust your EasyTunes6 hardware monitor to be right.

1.40v is nothing special one way or the other. Intel's data sheet says 1.52v max, and you know they built a fudge factor into what they published. Cooling/temps are as if not more important. If you are under load and seeing 70C, that's fine - you'll never get that high in day-to-day computing, and thermal throttling apparently starts at 95C so you have lots of headroom.

XMP - I had the same issue on my Gigabyte board. Picked up an Asus board yesterday, and it's cruising along using XMP. Recommended - set the speed AND timings of your memory MANUALLY rather than by XMP or Auto. Also, it is pretty common to raise vtt from stock 1.05 in attempt to gain stability. Recommended: do not exceed 1.20.

Thanks for the feedback, that pretty much covers the bases.

I haven't had much luck with this board to be honest, when I get it to boot into the OS overclocked everything is stable, but getting past the BIOs sometimes is a joke because it keeps shutting itself down and saying it's having overclock/voltages issues when this is a stable OC.

This generally happens on a gigabyte board when you use the reset button or after a crash. I flashed my bios, and the problem happens WAY less, but it is still there. It just happens to do with the way the PC was shut down most of the time. As mentioned above, check for a bios flash.
