After looking at some of the specifications of this memory, its time to stop talking and get down to some hard numbers. I'll be keying in on two main factors of this memory during the test phase; speed while running aggressive timings and bandwidth. But before I go into the details, we'll take a quick peek at the test system.

Testing will be simple and straightforward. After testing bandwidth speeds at default settings, I'll crank up the speeds to the maximum I can get while maintaining a 2.8v VDIMM setting. Timings will be kept at the 2-3-2 specs that Mushkin claims for the modules. TRAS will be set to 10 since the Athlon64 processors seem to do better with this setting.
Speed @ 2.8v
As noted above, voltage is limited to 2.8v due to motherboard limitations. Even so, I was able to maintain speeds of 242MHz while keeping the timings tight. Loosening the timings allowed me to get to around 250MHz, but this memory is simply too power hungry to get anything useful over this level.
After a 20% increase in memory speed, we ended up with about 18% extra memory bandwidth. Considering we were able to maintain solid timings and a 1T Command Rate, I was pleased with the overall results. Add to this the fact that the modules are designed to run at incredibly high voltage levels (higher than was available during this review), this adds even more promise to the picture.
So while you can expect to see very impressive speed with 2.8v, you can expect even more if you have the ability to run these power levels even higher. If you're looking for high power levels you have a few choices. You can get yourself one of the DFI LanParty motherboards that support this type of voltage level, you can see if your current motherboard is compatible with the OCZ DDR Booster, or you can check into a hardwired voltage mod for your motherboard.
