   This may not be the place for this and I apologize. However, I know many of you savvy techies may just be able to point out the obvious for me.  

I have been experiencing lockups and screen freezes related to memory. Upon reboot after the lockups the MB displays a C1 code. The manual refers to C1 in 2 locations one as bad mem and the other as cmos batt. After playing with this for several months. This is me being stubborn and not wanting to return the pc. I have come to the realization that it appears to be a MB issue regarding slots 1 and 3. Any stick of memory in slot 3 and the pc will not even attempt to post and you get the C1 code. Any combination of 0,1 or 2,3 and you get the long mem beep and a C1 code.  Currently,  the only way to run is either a single 2G Dimm in 0,2,1 or 2x2GB in 0,2(but still freezes on occasion).  The current freeze is accompanied by a burst of static or hung note from the speakers.There hasn't been any over clocking on this machine since I first encountered the issue. Roughly 2 months ago. I have run memtest on both DIMMS multiple times with no errors as long as they are run in 0. I have also updated the bios as well as enabling P1 and P2 options from 1600MHz or greater memory. Updating the bios gave a false positive as the problem did not occur again until a week later while running in 0,1.

	you better call them on Monday and let them take it from here, looks like you have done most of the tests and if your dimm is not working right then its most likely the mobo

	Quick question: Is it the same RAM stick that fails, or one of the slots on the motherboard itself?

	That's a common problem with EVGA's boards. I had 2 680i's with bad memory slots/memory controllers.

	I received the 2 replacement DIMMs at around 1940 this afternoon. I removed the old stick that was in slot 0 and booted up. Everything booted ok and I played around a bit. I inserted the second DIMM in and again got the same C1 code and long error beep. I reset the bios to default. I disabled the floppy and onboard audio. Also set the spectrum spread options all to disabled. I saved and rebooted again to the C1 code and long error beep. I then removed the second DIMM and moved it to slot 0. Thus, again, running with a single DIMM. Everything booted fine and is still running ok. i.e. It looks like the motherboard. It was too late to call I tried. So if ya see this before I get a hold of ya go ahead and send out a replacement motherboard. I will hold onto the memory until we see if the replacement mobo fixes the problem. I have 30days before its charged. If the motherboard fixes the issue I may just decide to keep the momory and you can charge for it then. If it doesn't I will be returning the replacement parts as well as the PC so that the problem can be tracked and determined.
