nanoseconds (lower is better)

At 800MHz with 3-3-3-9-1T the read-write-copy performances are pretty good. The copy and write numbers match the rest of the other boards, while the DFI's read numbers are lower than the DDR3 boards and even the nForce 780i SLI however the copy numbers (which are more important for gaming specifically) are larger. The latency according to Everest for the DFI is lower though.

Sisoft Sandra replicates the lower memory latency that Everest told us about, however it shows a far higher overall synthetic bandwidth than Everest and the DFI comes squarely mid-table.
