Overclocking on windows 8 and it's bugs.

[igotsnomoney]

NOTE: It's my second time over clocking (First Time on winXP) so this was rather surprising to me, might as well warn the other inexperienced OCers out there.

Over this long weekend, I decided to start over clocking my 1st gen Core i5 760 . I first started out at 3.2ghz and did a 3 hour prime test (I was planning to go higher). Onced that passed , I rebooted and stepped up to 3.8Ghz (my target). posted and booted no problem and proceeded to do some stability testing. ran linpack for a 10 times run on extreme settings, and then 29hrs of prime. it turned out to be stable so I was so happy. started battlefield 3 and thats when things went crazy. for some reason i started stuttering BADLY (multiple servers were tested), and between the stutters it would speed up (like youtube when the av sync is off and the video rushes ahead to correct it). so i thought this was weird. Tried single player and and noticed that the whole game was running faster (actual fps is the same but the game actions like reloading, running etc..). it was as if someone hit fast forward. Then i realized that even the windows animations of closing windows were significantly faster.

SOLUTION!!!

it turns out the culprit was windows 8 and its buggy (i know so many bugs with this, ill post it at a later time) hybrid boot process. How this works is even though windows is "shutting down" the computer, it hibernates the kernel, and other settings. Essentially it saved my cpu clock when it was at 3.2Ghz. so even though CPU-z an core temp was reporting 3.8, windows still thinks it was 3.2. as a result the os was receiving processed data faster than it expected causing everything to be faster. the battlefield 3 stutter was caused when the server tried to correct my superspeed.

for anyone OCing on WIn 8 in the future.

Go to:

Control Panel, power settings, change what the power button does, hit change settings that are currently unavailable, and then turn off fast boot.

For those people who have already OCed and are experiencing this. just hard reset your computer.

Either you aren't providing enough power to the CPU (due to the high draw from the GPU during games) or the CPU is getting too hot (due to the additional heat output from your GPU that wasn't present during the CPU stress tests. 

 

Try improving you case cooling, if you can, or just speed up the CPU/GPU fan(s).
