I have a asus 7v600-x mobo with an amd athlon 2400xp processor, win xp and 1Gb ram, the procesor that should run at 2.0 Ghz. Problem is when I set the bios settings to auto, it detects the processor at 2Ghz boots up fine but when I run a few processes the PC power goes. the screen goes black and no power. The only way to get it stable is to run the processor at 1.5Ghz. Is it an FSB problem, a better power supply or somthing else.
The Sack I'll give that a go and let you know, I'm using the heat sink and fan that came with processor as well as thermal grease. I have also noticed that the processor heats up to about 55-57 deg, which I didn't think was to hot for an athlon xp.
55-57 deg is OK for an athlon xp - my xp3000 runs at 65 degC with no problems
I would try running asus probe and monitoring the temperatures and voltages carefully
as you run the cpu faster, it draws more power, it may be that the psu is not quite up to the job. Because it is consuming more power it also produces more heat.
take off the side of the case and check the +5v +12v and +3.3v max ratings (not peak) of your power supply, and the make. Post these here.
click here download and install crystalcpuid and run it - see what it says are the current and original settings of your cpu - there are some rebadged athlons out there which are not what they claim to be - depends where you bought it from - if it is from a reputable dealer then they should be OK.
you have got problems there - you need to check your heatsink is properly installed and that the fan is working properly - Athlons should go up to 85 to 90 degC before you see a problem but instabilty is the first sign of temp problems, and you don't know how accurate the temp probe is.
