skav Posted February 27, 2009 Share Posted February 27, 2009 Tried these settins, my OS wouldn't boot, system reboots right before OS should boot. I noticed the DRAM timings on with my board were different, bios reported: 2nd Information: 1N-63-63-66 while your screenshot shows 2nd Information: 1N-61-63-66 I have bios version 1206. Any help appreciated gents! Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 27, 2009 Corsair Employee Share Posted February 27, 2009 Just to test the modules, try booting them with all of the settings above except the memory frequency. Try setting the memory frequency to 1333 and see if your system is stable. Link to comment Share on other sites More sharing options...
skav Posted February 27, 2009 Share Posted February 27, 2009 I assume the modules are fine since with default settings everything seems to work. I kept bumping the QPI and retrying. I have QPI somewhere around 1.55-ish and things seem to be stable. What application do you recommend to test the memory. Memtest86 and SiSandra seem to be the popular ones. Thanks for your help!

skav Posted February 27, 2009 Share Posted February 27, 2009 extended tests are failing, can't get this to be reliable at 1866Mhz. Im guessing the new bios and these settings dont jive. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted February 27, 2009 Corsair Employee Share Posted February 27, 2009 What do you mean by extended tests? In what test? And with memtest just use the default tests. Link to comment Share on other sites More sharing options...
Legend Posted February 27, 2009 Author Share Posted February 27, 2009 Change DRAM timing mode from 1N to 2N and see if that helps. Command Rate is highly dependant on the processor. Link to comment Share on other sites More sharing options...
DerekT Posted February 27, 2009 Share Posted February 27, 2009 Set to X.M.P. http://i259.photobucket.com/albums/hh293/DerekT2008/bios_select.jpg Then boot to memtest. Link to comment Share on other sites More sharing options...
skav Posted February 27, 2009 Share Posted February 27, 2009 will let you know with these settings. By extended, I meant letting it run for a long time. Link to comment Share on other sites More sharing options...
DerekT Posted February 27, 2009 Share Posted February 27, 2009 It will run as long as you like. I usually find a few passes enough, but it won't hurt to do it as long as you like. Keep in mind that there will always be anomalies sooner or later that can throw an error. When you are done, press the escape key. will let you know with these settings. By extended, I meant letting it run for a long time. Link to comment Share on other sites More sharing options...
skav Posted March 15, 2009 Share Posted March 15, 2009 finally got back to this, flipping to XMP is the answer. Thanks! Link to comment Share on other sites More sharing options...
DerekT Posted March 15, 2009 Share Posted March 15, 2009 Sure thing :): finally got back to this, flipping to XMP is the answer. Thanks! Link to comment Share on other sites More sharing options...
findnemo Posted March 9, 2010 Share Posted March 9, 2010 Hi Skav.. Do you face any blue screen on XMP mode lately or stable? I'm running XMP with latest BIOS version. Link to comment Share on other sites More sharing options...
