I have 2 genuine AMD Athlon XP-M processors that I have been using with my 462 board for some time now. The two chips are very similar and share almost the same specs, except for the rated speed & vcore of course. I have been clocking both of the chips to 2.4ghz without any problems but I have noticed something a little strange. The 2800+ seems to have outperformed the 2600+ @ 2.4ghz, by a lot! I've noticed a significant performance decrease when the 2600+ is installed and clocked in at the same 2400mhz mark. Using the same BIOS settings with both chips, I've run numerous tests and have found that I get higher fps with the 2800+ chip. Could the 2800 really be that more powerful than the 2600? I didn't think the two chips would perform any different really so I find it somewhat strange that when they are both clocked at 2400mhz, the performance varies. Does anyone have any info on this? I would appreciate anything that I don't know to be brought up. Thanks!
