I have a PC with a Gigabyte GA-8SQ800 motherboard running Windows XP Home, Service Pack 3 The motherboard has four 184-pin DDR DIMM sockets. It supports memory sticks in the amount of 128MB, 256MB, 512MB AND 1GB of unbuffered DRAM. The maximum amount of memory it supports is 4GB.
The computer has always ran fine with two 512MB sticks of RAM installed (Kingston #KVR400X64C3A). I attempted to upgrade the amount of RAM to the maximum of 4 GB, and installed four 1GB sticks of 1GB RAM in the PC (Kingston #KVR333X64C25). After I did that, the computer started having issues. The PC could run fine for hours or as long as a day or two, then suddenly it would reboot. When Win XP came back up, I would see a "this system recovered from a serious error" message. The reboots were sometimes preceded by me starting a browser or email client. Sometimes it would just reboot on its own.
To troubleshoot the RAM itself, I ran MemTest on the RAM, and it passed. I removed all but one stick of 1GB RAM and tried running Win XP with that amount of memory. Still got the error. Tried the 1 GB stick in different sockets. Still got the error. Tried a different 1GB stick in different sockets, Still got the error. It doesn't matter which of the four DIMM sockets is used, which stick of RAM is used, or even if I put a 1GB stick in some or all of the sockets. I am using 1GB sticks of Kingston value RAM, number KVR333X64C25. I even borrowed a different stick of 1GB Kingston #KVR400X64C3A RAM, which is the same model number as the 512mb sticks I was using, and experienced the same problem. I also had the computer do this when I was running a utility from a boot disk, so Windows wasn't even in the equation at that time. Heat is not a factor, either. I've added additional cooling..
The PC is still useful to me, and I suppose if it does not like 1GB sticks of RAM I can just avoid them. But if someone has any ideas they can pass along on what might cause the motherboard not to be able to support 1 GB RAM sticks, I would appreciate the help.
Thanks in advance for your time.
