Since there were no voltages for memory, we had to toss our normal overclock procedures out the window to bring you a better idea of the overclocking capabilities of this board. We have seen reports that this new ULi Reference Board, or more specifically the sister Reference Board with the dual 8X riser slot, can reach a CPU Speed setting of 400. Without memory voltage, the only way that this can be tested is by lowering memory ratios to those that can run at default voltage. In other words, we were only measuring the overclock capabilities - an important consideration, since this is a new chipset.

While we could not reach a CPU base speed of 400, we were able to run 300, which is very comparable to results with the NVIDIA nForce4. We also reached an overclock of 235 with our default 12X multiplier. Both these results are competitive with NVIDIA, and they are both outstanding, considering that they were achieved with no memory voltage control. Perhaps the latest version of the M1695 Reference can indeed reach a speed setting of 400. We have asked ULi for a Reference Board with dual x8 riser and we will bring you the test as soon as the board becomes available.
