I have a file server that has a Asus a7n8x Deluxe motherboard. I have been running it for years with a 2500+ Barton and 2 gig of pc3200 Micron memory. All has been fine with it. The other day I popped in a 3200+ (known good chip) and after about ten minutes of running it blue screened (win xp pro) I rebooted it and checked temps and everything and let it crunch for a while again. After about an hour it locked up tight. So with testing the system over the weekend I found out the motherboard must not like this memory running at pc3200 speed. I lowered the fsb on the 3200 down to 166 mhz and system was stable again. I bumped the fsb back to 200 mhz and lowered the mem speed down to 166 mhz and the system is fine. My question is any of you the ran this board in the past at 200 mhz or faster memory speeds remember which brand of memory you used. I don't want to play the keep buying until I find the right memory for the system deal and wind up with 500 1gb pc3200 mem sticks. From what I understand this motherboard can be very picky as to what memory it uses. The memory I have works fine in my Ubuntu box at 200 / 400 mhz and alson in my other server which has a Abit NF7-S in it.
