Posted February 15, 2015 So I just built a new H2O rig and did a small over clock. Initially CPU Z, EVGA's E LEET and AIDA's monitoring/ reporting showed the correct o-clock values, 4.0 Ghz on the CPU and all but very soon, like less than 30 sec they all changed to something like 1263 Mhz. So, you know I go back into the bios and everything looks good, 4.0 Ghz just like it should. Come back out, check CPU Z again and sure enough it switches in almost no time. Very weird. Just wondering if this is normal? I got the 5960X up to almost 4.9 Ghz but with a voltage at 1.39 - 41 I just knew it would burn, even with water, so I backed it down.

Posted February 15, 2015 Yes. That's normal. If you don't want the clock to reduce, set Windows to High Performance mode.

Posted February 15, 2015 Its called EIST or Enhanced Intel Speedstep Technology. It basically auto downclocks your multiplier to 8x when your system is idle to keep temps down and save power. You can disable it in UEFI if you wish.

Posted February 15, 2015 Yes. That's normal. If you don't want the clock to reduce, set Windows to High Performance mode. I always wondered why my clock speed was at a constant 4.4 in CPU-Z. Didn't realize performance mode did that. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
