just bought an asus a8n-sli with amd64 3500+ chip to replace my old a7n8x-x with amd2500+ chip. followed all the instructions and it boots into bios no problem. once in bios however, there are no drives. i checked the cables, replaced them with ones i knew worked. same thing. also, i put my ddr 333 mem (1.5 gig) in 3 of the 4 slots but it says i only have 0.5 gig. i`m probably missing something obvious. any ideas?
With regard to the memory, I suggest that you read the memory configuration section in the manual very carefully and check the memory that you have as it is very specific as to what can be used and in what configuration. The following is an excerpt from the online manual:
"Due to CPU limitation, this motherboard does not support DIMM modules with 128Mb memory chips or double-sided x16 memory chips."
Fred Heartsun Eric10 makes an excellent point above I didn't spot that when I had a quick look at the boards specs earlier. It has also reminded me that I have also had problems with ASUS boards and double sided RAM modules in the past - Eric10 may well have got this one for you.
all 3 modules are ddram 333, which are supported by the board. i`ll try resetting the cmos. oh. strange. the power supply yo the board is 20 pin but the mobo is 24 pin. what psu do i need? currently using a 550 watt psu.
