I'm having trouble setting my CPU voltage so it doesn't run too hot. I have an AMD Phenom X4 9850 BE CPU in an Asus M2N32-SLI Deluxe MB. Previously I discovered the auto-discover feature of the MB set the CPU voltage too high and I had to manually set it. This was stable for a long time.
My problem is I flashed to the latest BIOS upgrade and that trick doesn't seem to be working any more. CPU is supposed to run 1.05-1.3V, 61C max. Putting BIOS at "auto" for the voltage, CPU-Z reports it's running at 1.328V; I haven't found a temperature monitor for Vista 64-bit yet but the BIOS bootup says 68C, obviously too high. I've tried setting CPU voltage in the MB BIOS everywhere in the 1.05-1.30V range, even up to 1.320V, and it won't boot. I think I remember on the older BIOS, I got it to work at 1.100V. So ... I'm a bit of a noob at this, can I be doing it wrong? If I'm doing it right, what else can I look at? Or should I just revert to the older BIOS that worked? Last question, on XP there were several tools I found from Asus and others that let me manipulate these BIOS settings from within the OS; I can't find the same tools for Vista 64-bit -- can anybody suggest any? Specifically I'd like to set the MB voltage temporarily to see if it works, but if it doesn't, not have to pull the battery and set the RTC jumper just to get it back onto "auto" to boot again.
Thanks in advance.
