We had a chance to test a lot of memory over the past month and did we not only find some of the fastest memory on the market but some of the best value memory on the market. It was also interesting to see how the jump from 400 to 433, 433 to 466, and 466 and beyond works. While the Corsair seemed to take the lead at DDR500 speeds as soon as we started overclocking the OCZ memory, it really pulled away and for good reason it received our newest award, the TweakTown Performance Award.
433 and 466 didn't seem to have a huge affect on performance but as soon as we started hitting DDR500 speeds the performance jump was quite noticeable. Some people are going to be able to justify the cost of DDR500 (PC4000) while others will simply find it a rip off and unnecessary.
The decision on buying memory hasn't become any easier but we personally feel if you're in the Intel arena you should narrow the choices down a bit. If you're going to overclock go all out and look at buying PC3700 or PC4000. PC3500 doesn't seem to bring a significant jump for it to be considered warranted and if you're lucky you will find yourself reaching DDR500 speeds with some good quality PC3700 modules, such as the Corsair modules we tested here.
If you're on the other side of the scale and you simply want to run your computer at default look at the Kingmax PC3200 modules or Crucial PC3200 modules. Both are of very high quality and you shouldn't have any problems running them at 400MHz and even a little extra sometimes. If you're interested in a slightly cheaper alternative it may be worth considering the slower Transcend otherwise Kingmax's line of SuperRAM which we have looked at in the past may be a good option as well.
It doesn't matter what you're doing with your computer, there is RAM out there for everyone. It's simply just a matter of saying, "I want to get this out of my system " and making the right decision. Hopefully the above memory modules will give you an idea on what is perfect for your setup and you must realize that overclocking results vary from machine to machine. While we might hit X speed with these modules, you could hit 10MHz lower, but on the other end of the scale you could also hit 10MHz higher. It's a tough game the memory one and everyone needs it in their systems so it's definitely worth waiting and looking into what's right for you before making a decision.
