CMOS Checksum Error
Posted on 2006-04-21
I've got a new board from ASUS via an RMA. It's the P5N32-SLi Deluxe. It replaced my P5ND2-Sli board and I'm having issues again with the new one. The new board has is configured with:
Dual BFG 6800 GT OC'd video cards
2 Gig Corsair (4 x 512mb) XMS2 6400
2 WD2500KS SATA's
1 40 Gig Maxtor ATA
1 Sony DVD-RW
1 NEC DVD-RW
Enermax 600w Dual Rail PSU
You can see that I've put a lot into this system...but it will not function correctly.
When I first got it I loaded Windows 2 times with out problems and now it's really hard to get a desktop up and running. You see, the timings HAVE to be set for the memory to 184.108.40.206 or else I'll receive memory dumps. So say I booted for the first time. I enter the BIOs and make all of the settings to the memory that Corsair requires...I save the settings and reboot.
XP loads fine and runs perfectly. SLi is rocking, video games are flying, everything runs like it should and life is good. So I'm done with it and I shut it down for the night. The next day the computer will not boot.
Now I'm unplugging it from everything and putting it back on the bench to work on it. I pull the RTC jumper and set it to clear...wait a while, try to boot with the jumper in that location, move it back to default, pull it off completely, put it back on the default and eventually it will boot again.
Now it states that the CMOS Checksum is Bad and the settings are erased from the BIOS. I understand why the settings are earsed, but if I don't mess with the RTC jumpers...it will never boot.
How might I go about fixing this?
Thanks a ton,
