Since my old mobo fried a week ago I just bought an AsRock K7NF2-RAID, the new mobo here works fine except that I can't figure out why my Athlon XP 2800+ CPU refuses to run proberly on it, it outta run 2.0 GHZ but it seems that something goes wrong...
if I set up the FSB on the mobo to run 266MHZ this is the result in BIOS.
CPU host frequency [AUTO]
Actual Frequency [133MHZ] (*12,5 = 1662,5 MHZ)
53C/129F (if I spice it up a notch to [166MHZ] it just refuses to boot until I reset BIOS).
If I set the jumper on the mobo to run 333MHZ FSB this is the result in BIOS.
CPU host frequency [AUTO]
Actual Frequency [166MHZ] (*12,5 = 2075 MHZ)
Then it runs the 2GHZ it's suppose to but only for around 30 sec's then the mobo's safety thingy switches of the computer and refuses to reboot until I reset bios, if I let it run with the same FSB again ofcourse the exact same thing happends.
The old mobo had no problems running it at 2GHZ so I wonder what is wrong? could it be because the "safety thingy" is to sensitive or could it be because I didn't use thermal grease when refitting it onto the new board? I'm not entirely sure wheter to run it at 266MHZ or 333MHZ FSB since I'm not sure which CPU exactly it is, I was told it's an AMD Athlon XP 2800+ Barton but as of what I can see AMD made more than one 2800+ CPU.
On my old mobo I never touched anything besides the core clock because it was set to low, therefore I changed it from 133 - 166MHZ and since then it's been running 2GHZ, see this thread on the subject. (which also includes scrn. shots of the CPU and RAM).
Any help would be very much appreciated...
