DFI X48 LT T2R: Floats like a Butterfly…

Memory Write Bandwidth

Memory Copy Bandwidth

Even with the use of a high divider for 1200MHz memory speed at 3.6 and 4 GHz processor speeds, the DFI X48 cannot compete with the memory read bandwidth of the 780i reference board from EVGA. We tried all manner of BIOS performance adjustments. Standard tRD levels of 7 or 5 are unavailable at 400FSB and 500FSb respectively, hindering the synthetic figures somewhat. Copy and Write speeds are certainly competitive with the other boards though, but the overall picture is not impressive for a tweaker's board; we have seen DDR2-based X48 boards that do better.
