XMS2-9136 Memory Performance:
The latency decreases the faster you push the memory, even though the timings have increased. Interestingly, even though the DFI LANParty UT ICFX3200-T2R/G has completely independent memory controllers so doesn't use memory ratios, giving it a greater internal latency than the Inno3D nForce 680i SLI, it still progressively increases the performance. The Inno3D even has a decline in memory bandwidth, despite there being a reduction in chipset latency.
Even if you're buying super expensive memory, depending on what chipset you use can wholly determine your memory bandwidth, and even an increase from ultra low latency DDR2-800 to DDR2 -1142 is only a few hundred MB/s on some chipsets. In comparison, the memory bandwidth at DDR2-1142 on the Asus Commando is nearly 900MB/s faster than the Inno3D.
XMS2-10,000 Memory Performance:
As expected, we see a slight increase in the performance of the memory when using the faster XMS2-10000 memory. Even though the Asus Commando cannot attain the extra 44MHz the Inno3D can manage, the chipset performs again, significantly faster than any memory speed bump.
