Question about MSI K9A2 CF-F V2 AMD 790X AM2+ Phenom FX / Phenom X4 / Phenom X2 / Athlon X2 /AM2 Athlon 64 X2 / Ath... Motherboard
I just recently successfully flashed my Ami bios on my MSI K9A2-CF-F V2 motherboard. I just built this computer & didn't know I could not install more than 4 Gigs of memory (if that) on a windows XP Pro 32 bit OS. I was getting the initial one beep, than a 3 beeps on the logo screen after every restart. I noticed this after I attempted to overclock my system. In which was unsuccessful. I think I may have damaged my memory somewhat. However, the PC still boots successfully each time I restart, beeps and all. I never did register more than 3.5 gig of memory on Windows, but did register close to the 8 gigs of ram I installed in the bios. I'm using 4 memory sticks of Corsair Dominators, 2 gig a piece at 1600 Mhz, but only 800 Mhz registers in the Bios. I removed 3 of the sticks and left one in the first Dimm slot but still I get the beeps. I will try using one of the three I removed later, but was wondering if anybody knows if my motherboard is bad considering I can still reboot with no problems other than the (1)pause, (3) beeps? Any ideas? as I'm quite frustrated. Thanks.
According to the information at:
AMI beep codes of 1 long and 3 short are, in fact, correctly identified as memory errors. One thing to note is if this memory is Dual Channel, you can only install the memory in groups of two. You must first fill DIMM slot 1 and 3 before filling DIMM slots 2 and 4.
The below website has much more information about your particular motherboard and there's a note about some JEDEC setting for memory that you might want to watch out for or disable to see if it improves stability.
As for Windows XP 32-bit not recognizing more than 3.5 (at most) memory, this is unavoidable. To see all 8 GB, you would need a 64-bit version of Windows. This is something that cannot be altered by BIOS or memory choices, unfortunately. Feel lucky in the fact that you have XP Pro as XP Home will only recognize up to 2.5GB. You'll never utilize all 8GB unless you upgrade your OS, so keep that in mind!
