I've recently got myself an AMD Athlon XP 2100+ @ 1733 Mhz which I installed. The problem now is that it's only running at 1300 Mhz. Trying to change this in the BIOS gets me a black screen at boot, and then I have to restart, just to see that the processor is back on 1300 Mhz. How do I solve this problem? Thanks in advance!
