3770K Overclock

post #1 of 12
Thread Starter 
Hey everybody, I put together my first build just over a month ago now and I've got some questions. I've been running it at 4.4GHz with no problem (to me at least) using a Hyper 212 Evo. I just decided to install F@H and look at some of the numbers. About 30 minutes in so far and the cores are ranging from 75 to 86 C under full load. In CPU-Z, the core voltage is listed as 1.368. Since I overclocked it just using the multiplier in the BIOS settings (Z77X-D3H), I never touched the voltage myself and was wondering if I should lower that to something else.

Also curious to know if these temperatures are what's expected of a 212 Evo and at 4.4GHz since the heatsink was the most difficult part of my installation process and it might be messed up, but I'm not at all sure.

Thanks for the help guys!

edit ยป the voltage is only when it is under load it seems, with 5% load it is dropping as low as 1.104.

Hello, congrats on your first rig! Right now the voltage is at an auto setting, and is adjusting itself to what it thinks will be safe. However, 1.368v is MUCH too high for 4.4Ghz. I would highly suggest adjusting it manually, for 4.4, depenging on your chip, try 1.2v or 1.25v. Although, you're getting some good temps and might very well be able to get it up to 4.6 or 4.7. Just adjust it manually, if you need more help we have similar motherboards, I can give you some info on the settings to mess with. Best of luck! thumb.gif

Thanks for the tips and the link to that guide. I'll see about adjusting the voltage next time I reboot the PC but I'm more happy to hear the temps aren't out of the ordinary or anything like that. I'll report back when I change the voltage settings.

I tried it at 4.5GHz with 1.26 and it BSOD'd right away because of "memory management" so I put it back to 4.4GHz and it ran just fine and one of the cores (#1, not #0) went to 80 while the others stayed around 75.

Watching CPU-Z the voltage started jumping to 1.272 a few minutes after I tested it, not sure why...
post #6 of 12
are you using offset to overclock. maybe it is set to a "+"

I set it to 1.26, no plus or minus. The temperatures are better and the voltage doesn't go as high anymore which is good though.

Any idea why the Windows 8 Task Manager reports the "speed" as higher than what the processor is clocked? It acknowledges the maximum speed as 4.4 but shows "speed" as high as 5.8 GHz. I'm guessing it has something to do with the virtual cores or hyperthreading but I'm not sure.

Are you still running a pre release version of OS. There was such bug in the pre-release version. However, I don't know whether it was sorted out.

No, it's a fully up to date version of the Pro release (brand new key for this PC). I'll just assume it's some funky metric that causes the issue.

[VIDEOis no funky metric. TM just shows the total utilization of all cores in one graph. Just right click to select individual graphs.
