physx Posted January 19, 2007 Share Posted January 19, 2007 i have recently bought a new pair of 8500C5D's... when they were installed by the tech both ran fine on the mobo, although i was having issues with my 8800gtx.... so after i manipulated the bios for that to work it seems now that i can only get one of my 8500's working in the 3rd Dimm slot from the left. when both are installed i get a long continuous beep. i have tried amping the mem volts to 2.2v although it is unsuccessful, and with only one chip installed makes my PC lockup, it is more stable on 2.1v atm from testing. guru which settings do i have to enter manually for both dominator's to work once again. (note: all specs same except upgraded dominator ram) Link to comment Share on other sites More sharing options...
Yoxxy Posted January 19, 2007 Share Posted January 19, 2007 put both dimms in the 2nd and 4th slot. I believe this will correct the problem. Have you plugged a 4+4atx connector into the motherboard? Link to comment Share on other sites More sharing options...
physx Posted January 20, 2007 Author Share Posted January 20, 2007 hmm it seems i can run 1 ram module in any slot at a time although when the 2nd is introduced to the system it seems to only want to not boot up. i feel like i am missing a bios command or configuration move.

Corsair Employees RAM GUY Posted January 20, 2007 Corsair Employees Share Posted January 20, 2007 Do you have the latest bios installed that has corrected a lot of issues with memory and some with CPU detection? Link to comment Share on other sites More sharing options...

au.mrwolf Posted January 24, 2007 Share Posted January 24, 2007 Hey all, I'm the guy that built physx's machine and I have it with me now to try and get this all squared away. The last thing physx did was flash to 0702 bios. I can get the machine to post and boot with the ram in b1 & b2, but obviously it's not dual channel, and running prime on boot (not from within the OS) it soon locks up. All the timings are set to 5, 5, 5, 15, 2T 2.2v as recommended. Is there any worth in me trying to up the voltage to say 2.3 or 2.4 (and is this within warranty?). I had things working for a time at 0602 so should I maybe try that again to see if it resolves the issue? Any help would be great. Link to comment Share on other sites More sharing options...
Yoxxy Posted January 24, 2007 Share Posted January 24, 2007 Actually you can put the ram in any slots on the 680i chipset and it will be dual channel. The locking up is a problem though. That definetly should not be happening. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted January 25, 2007 Corsair Employees Share Posted January 25, 2007 Did you test them one at a time with http://www.memtest.org and with this MB you have to Disable Legacy USB when running http://www.memtest.org or any memory test.

au.mrwolf Posted January 25, 2007 Share Posted January 25, 2007 Yes, I use the Ultimate Boot CD and run the memtest from that. There are 2 versions on there and I've run both with the same result. I had to head out of the office today, so I will try out disabling the Legacy USB when I get back. I'll also try 1 by 1. Hopefully that's all there is to it. Is it true that any 2 slots will operate in dual-channel mode? That being the case it might be easier to carry on using the 2 slots that do work and not worry about chasing down an RA (as the shop I bought from is on the other side of the country). Does Corsair offer warranty with +/- 5% on the recommended 2.2v? And I'm using the 2x4 pin power option on the board rather than the single 4pin as I assumed this would allow more power through to the board. Should I change back to single 4 pin?

Corsair Employees RAM GUY Posted January 25, 2007 Corsair Employees Share Posted January 25, 2007 Just dont set it over 2.2 Volts in your Bios and you will be fine. Check the user manual for the power connectors If you never Disabled Legacy USB then that may be why you got errors. Link to comment Share on other sites More sharing options...
