I have an Intel Core i5 2500K with an Asus P8Z77-V LX motherboard, and the i5 2500K has been overclocked by Chillblast to 4.4Ghz, but it resets to stock Ghz when I boot into Windows. I was advised by their helpline to use Asus O.C. Profile to reload the overclocking settings, but when I booted into Windows afterwards it once again reset to stock. No matter what, it always resets to default overclocking on bootup. The overclock worked for 3 months up until now, and has been totally stable. This means I am stuck with a 2500K at stock speed, and a £35 CPU cooler which doesnt move from idle -_- any help on sorting this?
What has changed between when it was working and when it stopped holding the OC?
Have you done a BIOS update, replaced hardware...anything?
Nothing changed, one day it just wasn't overclocked. The BIOS hasn't been updated and no hardware changed either. I tried a CNOS battery reset a few days ago to try and solve it but that didn't work either :S
" I have to reload the BIOS setting everytime l press "save and reset" "
I wrote this when tired so no wonder it didn't make sense!
What I meant was that I load the settings from the BIOS, restart, boot straight into Windows, and the overclock has reset to standard. I'm not sure about a failiure, I thought it was at first, but it was perfectly stable for several months up until recently. I'll try overclocking it from 3.3Ghz to 3.6Ghz, I'll post my results
