joshcork Posted April 12, 2007 Share Posted April 12, 2007 Hey there I have 4GB of RAM and the system is perfectly stable once I get to windows 64Bit. But at every reboot I must clear the CMOS, and at that I get a CMOS checksum error, Defaults loaded message every time! weather I clear the CMOS or not, it has occasionally/randomly restarted without resetting the CMOS. I've tried the timings 5-5-5-18 @800MHz (defaults) 5-5-5-18 @800\667\533\400MHz 5-5-5-15 @667MHz 4-4-4-12 @800\667\533\400MHz all with voltage at 2.1 and a few with 2.2 SLI Ready was disabled LinkBoost option is not present With the setting below I can now boot consistently enough and now only have to have the PSU switch off for like 3 mins between boots. I had reverted to an older BIOS (0706) to see if the settings I was changing would have any better success, no luck there. Found that BIOS V.1001 CPU Frequency at 200.0 DDR2 Voltage at 2.1V Peg LINK in Auto (Default) DRAM CONFIG Speed at 667MHz Rest of theTimings in AUTO The Skew set to advance 450ps for both channels the SLI Ready to optimal AMD Live to enabled AMD Cool'n'Quiet in Auto Interestingly enough when I go back into the BIOS it correctly detects and sets the timings for my ram (4-4-4-12) usually they are set slower when the speed is 800MHz (5-5-5-18). With these settings I don't get a CMOS checksum error the occasional boot failure as restarting the PC doesn't work and it takes that rightly so as a failed post. Another week of this and I'll say I'll give up and get some other RAM that is guaranteed to work for this board, which is what I should have done in the first place. Any input to this issue Ram Guy would be appreciated Link to comment Share on other sites More sharing options...
