I have an X2 4200+ installed on this board. If I upgrade my BIOS to 1404, the BIOS suddenly claims that I have (128 MB, 0 MB installed) memory. The system can only address 128 MB from then on, WinXP, memtest etc all only see 128 MB. If I downgrade the bios to 1203 or 1302, my memory is detected fine again. This happens independantly from the memory config, i.e. one 1 gig stick, four 1 gig sticks, a 2 gig stick, etc. Also independant from the slot used. This happens with both the SLIC patched and original BIOS, as well as with or without CMOS clear. I'd like to use this BIOS version as it seems to fix issues with 4x 1GB RAM sticks, which currently give me errors in test 5 in memtest otherwise (the sticks work flawless by themselves) Any ideas?
