I have a Compaq S3000NX According to the website it has either an AM37 MB or an MSI MS6390 MB. My question is: What is the fastest Athlon XP processor I can use? MSI website says the fastest supported is 2200+ but the AMD website says their the MS6390 can support 2600+. I can't find any info on the AM37 either. I wanna upgrade the processor in it. If anyone can help it would be great. Bottom line: Can i use an Athlon XP 2600+ in my computer?
