I have a A8N-SLI Premium mobo. I just got a new AMD 64 4200 Dual core Processor to replace my 3500 Single Core.
I flushed the CMOS and have the latest (1303) bios. When I boot with the new CPU I get the 1 long, 2 short beeps with nothing on the screen. According to ASUS that is a RAM problem. I've tried all sorts of configurations with my RAM as well as cleaning them. I also reseated the video card (just in case). Still nothing... 1 Long and 2 short. I put back in my old 3500 and everything boots up fine.
Any chance this is anything besides the 4200 being bad?
Thank you all!

Set the bios to default settings. You probably have a multiplier or default RAM speed wrong, setup for the old chip.
