Test Results: Mushkin Redline XP4000

The top row of Performance results at 2.6V is included as a performance baseline. Like OCZ VX, Mushkin Redline cannot achieve 2-2-2 timings at stock voltage at DDR400. However, it can easily reach 2-2-2 performance levels at DDR400 with more voltage.

To be considered stable for test purposes, Quake3 benchmark, UT2003 Demo, Super PI, Aquamark 3, and Comanche 4 had to complete without incident. Any of these, and in particular Super PI, will crash a less-than stable memory configuration.

We reached an extremely stable DDR400 2-2-2-6 at 3.0V with Mushkin Redline XP4000. We then maintained 2-2-2-6 timings all the way to DDR546, which required 3.5V for complete stability. The voltage requirements from 3.0 to 3.6 volts were very linear to Memory Speed. DDR544 is the highest speed that we have ever reached with 2-2-2 timings, but it is only slightly more than the DDR538 2-2-2 achieved in our tests of the OCZ VX. Since both memories use the same memory chips, it appears that Mushkin and OCZ are both doing a similarly excellent job in binning the Winbond chips for their DDR500 2-2-2 products.

The important results here are rows 1 to 6, where CPU speed is kept at 2.4GHZ and only the Memory Speed is varied. The performance differences that you see in that range are a result of Memory Speed only. Since the Mushkin Redline also maintained constant 2-2-2-6 timings across the performance tests, the performance improvements are completely a result of memory speed only. It is not a huge difference in real-world benchmarks, compared to the huge increase in synthetic benchmarks like Sandra, but the increase is real nonetheless.

When you compare results of Mushkin Redline or OCZ VX, you will also see that all 2-2-2 is not created equal. Winbond and the revived BH5 are just a bit faster than other 2-2-2 memory at the same memory speed. Again, the difference is not huge, but where a computer enthusiast is aiming for top competitive scores, every advantage carries weight.
