DFI P35-T2R C1 error & POST Failure

[Guest JeB]

Hey everyone

I have had some recent issues with my DFI board. OK have had it once before but the C1 error has brought my system to a halt.

I was in the middle of burning a DVD and my system restarted. So I manually shut it down, then when I tried to restart, I got the C1 error.

OK so this is what I have done to try and resolve it

>> Use the EZ CMOS clear about 20 times over about 2 days

>> Removed the power cord and left the system for about 8 hours

>> Used the Clear CMOS pins

>> Removed the battery, power cord and left over night

>> Changed the RAM modules around in the slots - I have tried individually as a single module in each slot and in dual channel

 

The machine fails to POST at all and I cannot get into BIOS at all. Is this possible a BIOS chip failure, or buggered RAM modules?

 

I have had the C1 error before whilst trying to bench @ 4-4-4-12 @ 430x9 2:3 so I cleared the CMOS using Ez clear and removed the power cable and left it overnight and it came good in the morning. But this time I have hit a brick wall so to speak.

 

Any ideas as to where to go next?

 

Sweet cheers for the help

If you have been running the chips at 2.4 volts as indicated in your sig that could well be the problem. Try booting with one stick of cheap DDR800 or lower memory.

Ah OK I thought i may have killed my RAM - just out of curiosity, running too many volts into the modules, does it gradually burn the ram out or how does it work?

And with the P35 and GTL Ref settings could have boosted the volts over 2.4, I had them at 115, 115, 117 if thats any help

Thanks again for the quick reply I will grab a cheap stick to see if i can boot and look into RA'ing my RAM and see what happens.

Bummer

Thanks again

The ram gets to the point where it requires continually more voltage until it no longer works. The GTL values have no effect on ram voltage. They set the threshold for the logic switching levels at the processor.

Ok Well I have had my computer tested at the shop I bought my gear from, and to get it posting, they had to flash the bios using another set of RAM then throw the dominators back in again and that was it!

Would you believe that that was all, I had the 9/13 bios in there and they have rolled it back to 7/27 and at the moment have not tried tweaking it yet - have only just got hte system back so do some backups and then tweak again to see what effects have been had on the hardware.
