OK- RAM issues!!
This seems to be a common problem for a lot of people, so lets keep it here instead of having a million posts on the same topic.
Check here first for your systems problem-especially RAM issues.
Try setting up with 1 stick of RAM in DIMM1 first (closest to CPU). This will eliminate a badstick of RAM causing problems and confusing the problems further.
Note from Pauls FAQ: (some Crucial 256/512 ECC modules do not seem to be compatible)
A lot of people are having problems with CMOS checksum errors at bootup. This is due to either CPU setup or RAM settings. First clear CMOS properly:
Unplug cord
Remove CMOS battery
Cross jumper
WAIT 5 MINUTES
move jumper back to default
install CMOS battery
boot up
Configure you CPU manually with User defined settings- Start with default FSB and Multiplier for you CPU. Default voltage also.
Here are some RAM settings that cured my instability: I am using Bios 6G- I didn't see the need to update to 6N since I got it working.
From SoftmenuIII Setup:
DDR voltage= 2.75V
From Advanced Chipset Features/DRAM clock:
DRAM clock= 133
timing= manual
cas= 2
interleave= 4
Precharge to active(trp)= 2T
Active to Precharge (Tras)= 5T
Active to CMD= 2T
DDR DQS input= Auto
DDR DQS Output= Auto
DRAM que= 4 Level
Drive strength= Hi
DRAM Command= 2T (try this first- if stable then try 1T)
DCLK Feedback= 0ps
I also enabled the 15M-16M memory hole- probably not necessary.
Post back here if these settings work for you. Also if you have a different configuration settings that worked for you, post them here!! I had the same Checksum errors as many of you on installation, so try these first- it worked for me. This board is awesome, but I do think it has some instability/setup issues with the default RAM settings and proper CPU recognition.

Anyway, did anyone else try installing XP prof on this board WITHOUTinstalling the new 4in1 drivers? DAAAAAAAAAAAANG that was sloooooooooW! wow! Anyway, now, it's incredibly FASTER! So, has anyone had this thing overclocked? I'm just wondering, b/c I haven't been able to get jack done on this thing!
