Vette Posted December 20, 2005 Posted December 20, 2005 Ok so I just got my mobo back from RMA and they said its a-okay, and its still blue screening and failing prime. They said that it had some sort of bios memory error and that they fixxed it. So im putting my ram through its paces atm and have discovered that my board wont boot in single channel mode if the ram is in one of the bottom 2 slots(closest to CPU) but boots up fine in the top 2 slots. Is this normal or something I should be concerned about? Now that I have prime95ed a little bit with both sticks in single channel mode. stick A failed prime after 30 seconds. Stick B is still stable after 15 minutes and is still going. So now im thinking that this stick of ram is bad....but that would be insane because I RMAed my ram before my motherboard because I thought the ram was the problem. So did OCZ take my bad ram and send me more bad ram? or worse, did OCZ take my GOOD ram that wasnt working in my broken motherboard(supposed BIOS memory problem) and sent me back bad ram that doesnt work in my now working motherboard? I'm so sick of this crap, i just wannt get them stable so i can sell em off to a co-worker before they screw up again. I have all the power connectors plugged in my power supply if flawless, ive tested it. my processor is fine, its stable in other comps, but other procs arnt stable in mine Any advice would be greatly appreciated.

KimTjik Posted December 20, 2005 Posted December 20, 2005 I can't get the picture, so please tell me: in what slots do you now have the RAM, in the yellow or orange ones? Share this post Link to post Share on other sites More sharing options...
smolt Posted December 20, 2005 Posted December 20, 2005 check them one at a time in the slot the farthest from the cpu and run memtest on them one at a time if they pass them put them in the orange slots Share this post Link to post Share on other sites More sharing options...
Vette Posted December 20, 2005 Posted December 20, 2005 right now stick b is priming stable in the top orange slot. stick b failed prime in the top orange slot. i was under the impression that the yellow slots never work right on any ultra-ds Share this post Link to post Share on other sites More sharing options...
wevsspot Posted December 20, 2005 Posted December 20, 2005 My assumption would be that stick A ram is defective. You are testing them in the exact same slots with the exact same BIOS settings correct? If test platform is constant from one test to another, the only logical conclusion is that unfortunately you've ended up with a bad stick of RAM. Sorry for your frustration and your poor luck.

smolt Posted December 20, 2005 Posted December 20, 2005 you need to run memtest prime can fail for other things besides memory Share this post Link to post Share on other sites More sharing options...

Vette Posted December 21, 2005 Posted December 21, 2005 update: both sticks passed 9 hours of memtest in single channel mode. stick A still fails prime95 instantly and stick B passes. im running out of things to try Share this post Link to post Share on other sites More sharing options...

Vette Posted December 22, 2005 Posted December 22, 2005 Comand per clock was enabled. is that bad? Share this post Link to post Share on other sites More sharing options...
KimTjik Posted December 22, 2005 Posted December 22, 2005 Neither is bad, it just a question of trying to optimize the system. See link and you notice that the difference in perfomance isn't that big. For stability disabled (2T) could be a good option. http://www.dfi-street.com/forum/showthread.php?t=31584 Share this post Link to post Share on other sites More sharing options...
Vette Posted December 22, 2005 Posted December 22, 2005 disabling CPC made the rig stable in dual channel. Why am I not able to run with it enabled though? Any idea? Share this post Link to post Share on other sites More sharing options...
