Nathan Kirsch's Thoughts:

Low latency DDR2 memory has been something enthusiasts, gamers, and overclockers have been waiting for since DDR2 first came out without luck. Luckily enthusiast memory giant Corsair stepped up to the plate and hit a home run with their PC-5400UL memory modules. These modules turned out to be dual purpose in our opinion as they can run tight timings (CL3) up to around 750MHz and then run all the way up to a 1GHz at CL5. For the first time ever we are seeing numerous test samples hit over 1GHz and do it with stability! If you are looking to plug some modules in and run tight timings these will work perfectly. If you are that die hard overclocker looking to hit over 1000MHz on your memory look no further!

In terms of raw performance the modules don't shine like they should till the front side bus is raised. When keeping the FSB at 266MHz only marginal bandwidth gains were noted, but when the FSB was raised above 300Mhz (QDR 1200MHz) the scores vastly improved. With new chipsets like the NVIDIA nForce 4 SLI Intel Edition and the Intel i955X Express now on the market Corsair has selected the perfect time to launch their 5400UL modules. I also find it ironic that these brand new modules already push the new chipsets to their limits in terms of memory bandwidth. We were able to hit 1066MHz with some stability, but overclockers like "The Stilt" have already reached 1170MHz on volt modded motherboards with Corsair's 5400UL memory.

At the 2005 Consumer Electronics Show (CES) memory companies were talking about hitting 700MHz or 800MHz in their test labs and how DDR2 sales are slowly picking up. Like many others in the industry DDR2 didn't look that good to us till Corsair brought out their PC2-5400UL part. If you were waiting on upgrading to a DDR2 platform now might not be a bad time to take that plunge. Intel and nVIDIA have released their new dual core chipsets, PCI-Express video cards are out in mass, and DDR2 memory has finally passed up DDR1 in terms of perfomance. What are you waiting for? Jump on the DDR2 bandwagon! I'm sure our AMD fans will migrate over later when those next generation processors and boards come out.

A one gig kit of PC2-5400UL currently runs $240 shipped to your door, which is a heck of a deal for memory that can overclock over 1GHz if you are lucky and have the right hardware! Right now Corsair only offers the modules in 512MB capacities, but most people run 2 x 512MB anyway. If you are looking for some DDR2 memory we have found that Corsair's PC2-5400UL is the best that we have seen to date. Add this one to the top of your memory shopping list!

Those latencies look good. Athlon-64s would love them imo.
Another GHz-er ;(
