Fest1984 Posted April 11, 2013 Share Posted April 11, 2013 Hi all. Apologies in advance if this is an easy answer, but I've spend the last 24hours scrolling through countless pages on various forums etc. I've just build myself a new pc which has the following spec: ASUS RAMPAGE IV EXTREME X79 Intel Core i7 3930K s2011 6GB EVGA GTX TITAN SC Signature CORSAIR CMZ64GX3M8A1866C9 CORSAIR Hydro H100i CORSAIR AX1200i 512GB Samsung 840 PRO SSD Basic Asus BW-12B1ST BD/RW Creative SB ZxR MS Win 7 Pro 64bit OEM Everything is running, but after the initial installation I was getting BSOD every 5-10mins I had a look at the bios settings and the RAM speeds were really low, so I read the ROG forums about overclocking of RAM and saw someone's post with similar issues: http://rog.asus.com/forum/showthread.php?24203-Asus-Rampage-iv-extreme-Memory I went back into the bios and turned on XMP setting in the bios and it increased most of the memory rates to the XMP profiles spec but when I view the details in mem tweakit my DRAM freq is only 933 I have altered the secondary timings with the info gained from the XMP list but there are some details missing for DRAM Refresh interval and all the tertiary timings. can anyone help me with regards to timings so the memory runs at the desired speed of 1866mhz. here is a picture of current settings http://img705.imageshack.us/img705/4592/23520443.jpg http://img46.imageshack.us/img46/8797/16931424.jpg http://img827.imageshack.us/img827/2318/29018088.jpg Link to comment Share on other sites More sharing options...
peanutz94 Posted April 11, 2013 Share Posted April 11, 2013 Just enable XMP and leave it alone. DDR stands for double data rate. So you would take your 933mhz x2 = 1866mhz It's running where it should be. I have altered the secondary timings with the info gained from the XMP list but there are some details missing for DRAM Refresh interval and all the tertiary timings. Set the first 4 and leave the rest on auto. There is no need to alter secondary timings. Your MB will set them where they need to be. Link to comment Share on other sites More sharing options...
Fest1984 Posted April 11, 2013 Author Share Posted April 11, 2013 oh dear ¬_¬ thanks anyway for your help, its much appreciated. the secondary timings were only slightly different from that to the xmp profile but it upped it from 533mhz to the 933. once again cheers :) Link to comment Share on other sites More sharing options...
