ULi M1695 PCIe/AGP for Athlon 64 – Part 2 with SLI

Overclocking Comparison

Maximum overclock data was added to Performance graphs beginning with the nForce4 SLI roundup several months ago. The overclocking performance graphs should allow better comparison of the overclocking capabilities of tested boards. For more details on the specific overclocking abilities of a specific board, please refer to the Overclocking and Memory Stress Test section of individual board reviews.

The overclocking performance of the ULi M1695/M1567 Reference 2 was impressive to say the least - even more impressive than the excellent Reference 1 ULi board. 242 Clock Frequency at stock multiplier is one of the highest overclocks that we have ever seen with this reference processor.

400 at the lower 7x multiplier is truly amazing, and it is the highest value that we have reached in any testing. Keep in mind that this is not our standard base DDR400 overclocked, and is not directly comparable to past results. Therefore we did not include a performance graph with the 400 value with lower multipliers. We always test to see the highest value that we can reach on any board before settling back at the DDR400 overclock. The ULi is just amazing to reach 400 CPU Base Clock in our tests, which certainly indicates a robust voltage regulation with this chipset. We are very happy when we reach a 50% CPU Base Clock OC (300) at lower multipliers. Reaching 100% Base Clock Speed OC (400) is rare.

ULi's claim that a base clock speed of 400 was possible met a lot of skepticism here, but the board did exactly what ULi promised. To be fair, it is mostly just a bragging point and has little impact on performance until ULi also implements the companion vDimm adjustments and expanded vCore to make 400 a true performance booster, but it is still impressive.
