DDR2 The Second Round :: Corsair XMS2 PC2-4300 Pro

Corsair returns this time with their PC2-4300 Pro. The memory features lower latencies than the bigger brother but also comes at a slower speed. Like the bigger brother, the XMS2 PC2-4300 Pro comes with flashy LED lights to show memory usage. It's not as fancy as the ones found on the Tracer but it still looks really good.

Because the Corsair Pro series features their custom LEDs, the PCB used is a customized as well. This is to help dissipate heat off the memory chips. As mentioned earlier, one of DDR2's main goals is low heat output, so I don't think these large heatspreaders will help more than regular heatspreaders. But if it's larger there's no harm in that.

The Corsair PC2-4300 comes rated at 269MHz with timings of 3-3-3-8 and a low voltage of 1.8v. Corsair was good with the voltage, allowing it the appeal to more enthusiasts. I'm not so sure why, but a lot of people don't like to pump extra voltage into memory even if it's safe. They'll do it to the CPU but not memory.

Corsair's PC2-4300 Pro was the best overclocker today in the roundup. Using the same "fatty" micron chips, I was able to reach low latencies of 3-2-2-8 at 266MHz. Increasing the FSB, I reached over PC2-5400 speeds with the same low latencies. The low latency topped off at 346MHz, roughly a little over PC2-5500. This is certainly exceptional stuff here. With a little more loosened timings of 4-3-3-10, I had no trouble going to the limit of my CPU. The chips in these sticks are truly the best of the best.
