Geil PC3200 Ultra X: High Speed & Record Bandwidth
 

When Corsair 3200XL appeared on the market about 2 months ago, it created quite a bit of excitement with 2-2-2 timings at DDR400. After disappearing from the market when Winbond BH5 memory chips were discontinued, 2-2-2 DDR400 memory had become available again. At that point we certainly did not expect the flood of new 2-2-2 DDR400 memory that has appeared in recent weeks. It now seems that every major memory maker has a new PC3200 2-2-2 memory in their product line. Considering how popular low-latency memory is with computer enthusiasts that is certainly understandable.

We reviewed six of the new DDR400 2-2-2 dimms just a couple of weeks ago in =F-A-S-T= DDR Memory: 2-2-2 Roars on the Scene. Geil has introduced another fast PC3200 memory with their PC3200 Ultra X rated at 2-2-2-5 memory timings. This brings to seven the number of new DDR400 2-2-2 memory offerings that we know are now available in the marketplace. With a selection like this you can finally make some choices in fast DDR400 memory based on value as well as performance.

The most remarkable trait with the new DDR400 2-2-2 we have tested so far is the incredible bandwidth they have demonstrated. All of the six tested memories reached DDR500 with decent timings and a bit more voltage. This kind of bandwidth is unique in the memory market, and it makes the latest DDR400 as close to universal memory as you will find in the market today. You get the fastest timings possible at DDR400, plus greatly extended bandwidth that can take your performance to DDR500 or beyond.

The other side of the equation is the fastest performance at DDR400. In that regard, every one of the six 2-2-2 DDR400 dimms we have tested met the specification of the fastest 2-2-2 performance at DDR400. Most managed these fastest timings at default voltage of 2.5V to 2.6V.

The questions with the Geil PC3200 Ultra X then, is how it compares with the fast DDR400 memory we recently tested. Is this another Samsung or Micron-based memory with great timings and an incredible bandwidth? Can the Geil compete with the best from the fast DDR400 roundup? Can anything approach the incredible bandwidth of OCZ PC3200 Platinum Rev. 2 that reached all the way to DDR557?
