12GB - 6x2GB A-Data 2000X
@DDR3-1909Mhz 7-8-7-25 2T at 1.62v
(Kit 1 + 2: module #1 + #2 + #4 + #3 + #5 + #6)

Now to test higher memory frequency with 7-8-7-25 timings at 1.62v vdimm. 1T results in ~10% more memtest86+ v4.0 reported bandwidth than 2T, but 1T was only stable for Super Pi 1M and failed 32M. 2T was much easier to pass Super Pi 32M @DDR3-1909Mhz 7-8-7-24 2T with tRFC 110, tFAW 37 and B2B 4.

Swapped module #5 and #2 places so the 6x2GB A-Data 2000X config is as follows module

• Dimm 1 = module #1
• Dimm 2 = module #2
• Dimm 3 = module #4
• Dimm 4 = module #3
• Dimm 5 = module #5
• Dimm 6 = module #6

System:

• Intel Core i7 920 3845B260
• EK Supreme LT 1366 / FESER 480 / MCP655
• Asus P6T6 WS Revolution
• A-Data Xtreme Series 2000X 9-9-9-24 1.6-1.8 rated memory
• 512MB Inno3D 8800GT OC Edition 190.62WHQL
• 750GB Samsung SATA
• Pioneer DVR-217 DVD-RW
• Corsair HX1000 PSU
• Dual Boot - WinXP Pro SP3 (nLite fully updated) with Vista Theme & Win7 Ultimate 64bit RTM

1T RTL A/B/C = 58/60/62

2T RTL A/B/C = 58/60/61
