NF3 250Gb Cold Boot Problem...

Recommended Posts

I have this rather weird problem with my current setup, you see I ditched my GIGABYTE K8NS Pro a couple of weeks back since I was having several problems with it especially with memory speeds. So anyway I jumped on the DFI bandwagon haven’t looked back the board is great, finally got my DDR400 memory to run at the actual speeds for once, but I’ve had a recent problem upon me putting in my other Corsair CMX512-3200C2 stick that just arrived back from an RMA Process.

 

The problem lies when I turn off my computer at the power point or leave it switched off for some time using the PSU switch at the back of the case. Upon cold booting my computer will not post at all, but if I take out one stick of ram it boots up fine. Same goes with the other Corsair stick they both work fine on there own but if I seat them into the DIMM slots and reboot the BIOS recognises 1GB of total ram and its been stable for about 2 days now playing Battlefield 2, video encoding ect. I had to repeat this pretty much each time I turned off my computer but, so this is why I’m posting I’m baffled as to what’s causing this problem. I considered the CMOS battery to be the problem but although the board is new and hasn’t given any indication of BIOS settings being lost I don’t think it could be the setback.

 

Encase your wondering the Corsair ram is not duel channel, and both are different revisions v5.1 and v5.2 so this may explain why. I’ve also included some screenshots of SmartGuardian and CPUZ if that’s going to help identify any further problems.

 

Any help to revolve this issue would be greatly appreciated.

Have you switched DIMM slots for each stick of memory? Tried both 1 and 2 and 1 and 3 (possibly even 2 and 3)? The mixed ram could pose a possible issue if they're different memory chips...

I havnt tried DIMM 2 & 3 but I have tried DIMM 1 & 3 with no go will try that combo and post back results.

 

Update: I've tried DIMM 2 & 3 but its still doing the same thing. Considering purchasing this memory for my board if nobody has a solution. Wanted to know if anyone recommends this specially for NF3 250Gb? OCZ Gold C2 PC3200 EL DC CL2 DDR 1Gb Kit.

Boot with each module individually using cpu z to find rated timings under the speed header for each of those modules. Compare the cas latency etc. The cas latentcies etc. if not matching can cause issues but can sometimes can be overcome by manually setting the specific timing in the bios to the larger value of the two respective latentcies. This often solves the issue of using different modules but NOT always . Good luck keep us posted.

OK, did a fair bit of testing regarding your methods, but nope it just dosnt like my specific Corsair ram. Anyhow im switching over to OCZ so I basically wanted to know if this OCZ memory will work ok with socket 754's since it there is no duel channel on the NF3 250GB 754 mobo afaik.

Well I just put the OCZ in and its still doing the same thing, ill try the BIOS see how that goes.

 

Update, I tried an older BIOS but it produced the same result. Im wondering if the board needs to be RMA'd at this stage, because I've tried 3 different types of memory brands and it simply wont post with 2x512. But with 1x 512 it posts fine,also on the same topic would cranking the DDR voltage to 3.00 make any change?
