Performance Drops After Overclocking

by Jacky Boen / December 18, 2007 10:32 PM PST

Hi, i'm having a problem. Whenever i overclock my CPU higher, the calculation in SuperPi becomes slower and the number of fps in games also drops. If i set my CPU clock back to normal, the performance becomes even worse unless i press the Reset CMOS button on the motherboard.

I wonder what could be the problem? Can anyone help me please?

My CPU is Intel C2D E6400 @ 2.13 GHz(I overclocked it to 2.8 GHz). I have 2x1GB A-Data Vitesta Extreme Edition(DDR2-800). Motherboard is MSI 975X PowerUp Edition with BIOS version 7.16. Anything else you need to know?

Its very important that upon OC'ing that cooling becomes even more critical. If your current cpu HSF is what was installed to the cpu was factory, it won't support beyond a given cpu level. In other words, if the HSF support only 2.13, then anything above that with factory setup just won't do, replace with a better one for 2.8 or 3.0. Again, no details on just what the HSF is. While you have extreme editions of ram, they too must support or be good match for the upmost stable system, review those specs and see what they apply for. The whole system must come into play to support the OC'ed level while the MSI seems friendly to OC'ing to get to a wall and thus peter out, again cooling is so important, if you have added cooling or rely totally on current cooling, it may not be enough. Also video cooling fan if installed add a slot fan next to it to better exhaust. The mtrbd. maybe sensing a heat build-up and plays it safe and causes reduced level of cpu output in order to save the cpu from damage, review what bios protection schemes are used and/or at least the "over-temp" level. The cpu has a over-temp build-in with no user input, so beware of that, it as said can reduce output to save itself or even shutdown system or reboot depending on bios setting.

did you also adjust memory speed and check CPU temps?

when you OC by raising the fsb, the bios may reduce your memory speed. depending on your bios, you'll need to set your memory speed manually or choose a different memory multiplier.

also, that's a substantial OC. have you monitored the CPU temps? if you're hitting over 65C the cpu may start thermal throttling (slowing itself down to cool off).

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
