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?
Are you using XP 32bit or 64bit? If you are using 32bit Windows, then why are you even bothering to try and use anymore than 2gb of RAM? It is completely pointless using this much RAM on a 32bit OS, only 64bit OS's can utilize more than 2gb of RAM... What is wrong with the previous BIOS's, if they pick up your memory fine then why bother upgrading to a BIOS that is still in the Beta stage? I wouldn't waste my time with this, I would just use the BIOS that recognizes your RAM and be done with it!!
for one, yes, 32 bit OSs CAN use more than 2 gigs of ram. they can only manage 4 gigs in total, so videocard ram etc is substracted from it. second, like I said, the bios that detects the ram has issues and gives me memory errors and bluescreens. the 1404 bios is supposed to fix issues with 4 sticks of ram. that is why I wanted to use that. I got it to work now with the old bios, although I had to increase ram voltage by 0.1V and lower the ram frequency a little. my 32bit winxp is now running (and using) with 3.58 GB of RAM. I hope that if/when 1404 is fixed, I will be able to run it without any voltage increase or speed change.
Necroing this thread but I got the same problem as the OP the only huge problem is that I can't downgrade the bios because it doesn't let me to do it. Any way I can downgrade it? Tried awdflash but doesn't let me downgrade. Any ideeas?
