Corsair folks were kind enough to send me a set of their flag ship DDR3 kits, 2GB Corsair TW3X2G2133C9DF Dominator dual channel memory rated for 9-9-9-24 at 2.0v. These are apparently based on Samsung ICs. The memory packaging seems to be dated week 31, 2008 while the SPD according to Everest Ultimate 4.60 reports week 19, 2008.

​

I decided to start off with DFI UT X48-T3RS with newly first time flashed 8/29 official bios, along with swapping in a new E8600 Q820A599 which has never been tested on this motherboard before. I kept the 2x 512MB HIS IceQ3 Turbo HD3850 Crossfire video cards in place but updated from Cat 8.7 to 8.8 drivers. So it's new video card drivers, new bios, new cpu and new memory first look so to speak :)

System specs

Unfortunately, max fsb on DFI UT X48-T3RS is still stuck around 500-510FSB. So no way to hit the rated memory speeds for this 2x1GB Corsair TW3X2G2133C9DF Dominator kit. I'll be trying the memory on other motherboards later.

For now some quick tests at DDR3-2000 9-9-9-24 1T at 1.874v bios set and DDR3-2000 8-8-8-21 1T at 1.915v.

Will try tighter timings tomorrow :)
 
DDR3-1820 7-7-7-24 2T at 2.00v bios set​
Trying tighter CAS7 timings, it seems Samsung ICs don't have the same mileage as Micron D9GTR/GTS/JNM needing around 0.1v to 0.18v more vdimm to hit DDR3-1800 7-7-7-x. But could be I haven't had much time to tweak and tune with the new cpu, bios and memory so far. I've managed to tune it somewhat by changing DRAM Default skew models from 1 to 6 and dropping DRAM CLK Driving Strength one level from 6 to 5. 2T was slightly more stable than 1T although mem clock ceiling was about the same.

Super Pi 32M = 11m 51.656
