First memory results on this forum

OCZ Platinum DDR3-1333Mhz 7-7-7-24 (OCZ3P1333LVA6GK 'Animal Series') memory modules are Micron DDR3-1866-2000Mhz CAS9 binned ICs sprinkled into the regular OCZ Platinum DDR3-1333Mhz series and are differentiated by the 'A' in the product code.

• OCZ3P1333LVA6GK = Animal Series with Micron DDR3-1866-2000Mhz CAS9 binned ICs
• OCZ3P1333LV6GK = Regular OCZ Platinum DDR3-1333Mhz.

Let's see how these modules do on Asus P6T6 WS Revolution.

System:

• i7 920 C0 3836A756 #2
• EK Supreme LT 1366 / FESER 480 / MCP655
• Asus P6T6 WS Revolution
• OCZ Platinum DDR3-1333Mhz 7-7-7-24 (OCZ3P1333LVA6GK 'Animal Series')
• 512MB Inno3D 8800GT OC Edition @742/1836/2000
• 750GB Samsung SATA
• Pioneer DVR-217 DVD-RW
• Corsair HX1000 PSU
• WinXP Pro SP3 (nLite fully updated) with Vista Theme

Back to Back CAS# Delay was left on AUTO which defaults to value of 0. The default Command Rate (DRAM Timing Mode) when set to AUTO seems to change to 2T at high memory frequency CAS9 memory clocks. So I decided to run DDR3-2000Mhz 9-9-9-24 2T first and then manually set to 1T DRAM Timing Mode for a 2nd set of benchmarks as follows:

• DDR3-2000Mhz 9-9-9-24 2T at 1.66v vdimm, 1.50v QPI/DRAM (CPU VTT uncore voltage)
• DDR3-2000Mhz 9-9-9-24 1T at 1.66v vdimm, 1.50-1.51875v QPI/DRAM (CPU VTT uncore voltage)

Super Pi 1M, 32M, Everest Ultimate bandwidth tests for 2T managed with QPI/DRAM of 1.50v only 1T config's Hyper Pi 8x16M Pi test required bumping QPI/DRAM from 1.50v to 1.51875v
