Looks like some serious issues with those DDR3-2000+ kits.http://www.anandtech.com/memory/showdoc.aspx?i=3596ASUS Rampage II Extreme (1406 BIOS)Intel Core i7-975 Extreme Edition w/Thermalright Ultra-120 eXtreme 1366 RTMushkin Redline Ascent 6GB (3 x 2GB) DDR3 1600 (PC3 12800) (6-6-5-18-1N)EVGA GTX 285 2GB FTW (186.18)Creative Sound Blaster X-Fi Titanium Fatal1tyWD VelociRaptor 150GB

interesting, so what clock did you end up with on your 975?

Clock what clock, LOL.I

I see absolutely no reason to go from DDR3 1600 6-6-5 to DDR3 2000 even at 7-7-7 timing. Although there are benefits to being @ DDR3 2000 those are not great enough to warrant the cost or the headachesI said it before and I will say it again.. these memory companies are all pulling a fast on with DDR3 1866-2000 and i7. There are issues with this and the C0 stepping procs and even my contacts at Intel said what they are doing is questionableWhen they design memory that will run @ 1.37-1.42v QPI stable and maintain CAS7 and under at DDR3 2000, THEN that purchase has value and a lot of it. Until then as an engineer, I haft

For 4.4GHz with a 975 on the Rampage II Extreme, you might like to try this:Load Line Calibration: EnabledBCLK: 133MHz (actually ~133.6MHz)Multiplier: 33vCore: 1.35000vvQPI: 1.36875vvIOH: 1.25919vvICH: 1.13991vvDRAM: 1.65681vOther voltages on Auto; HT, thermal & other stuff all disabled.Tim
