thats dfi for you period.i have a dead 680i lt(back from repair and dead again) and a rd600 dead with c1 errors on each board.even before they just totally stopped working they would do the same thing"c1" crap.im done with dfi i think for a long time,im so sick of there c1 errors even with modest clocks.i used to think dfi was the best baords on the planet,now i know there the best bios,thats it...there dfi ultra d series was the last of the bullet proof boards.
Yeah, I've tried just about everything that I can think of--increasing NB all the way up to 1.45V and increasing Vdimm up to 2.1V--and I still can't get away from the "C1" error on cold boot and the occasional "C1" error on reboots. My settings are now 24 hours stable using both small FFTs & blend. I have also exceeded 20 passes using memtest 2.01 w/o any errors. I posted the same question over on Clunk's site any he couldn't offer any advice either.
I have to admit though that this isn't just a DFI issue because I have had this same problem using an Asus Maximus Formula. The problem didn't arise with that board though until I started using my QX9650, there was no "C1" issue using my x6800. So I am wondering if it isn't the QC that's leading me down this road of frustration....
