I have a MSI K9N2 SLI with Phenom II X4 945. Ran well, installed Win7 but core clock speed was only 800Mhz. I set the multiplier to 15x in BIOS, but then system wouldn't boot. Cleared the CMOS. Computer booted fine but fans are running hard.
I realize at this point I need to update bios from 3.3 to 3.5 to get support for this CPU... however, checking BIOS to see why fans are working overtime I seen that CPU voltage is at 1.8 (should be 1.3) and system temp is 78C! What's worse, it won't let me change the voltage.
So I figure if I'm going to do the BIOS update I have to do it quickly and with a big fan pointed at the CPU. It will still boot into Windows 7. I have the Windows BIOS update tools and this would definately be the quickest and easiest way to do it. BUT... does anyone know if this works with Win7?
Alternatively I could probably find an older CPU that I don't care about (and that maybe uses a higher voltage anyway), do the bios update and then reinstall the X4.
Any better ideas?
