AMDZone comes along first having tested out two 512MB sticks of Corsair PC3200 Cas 2 DDR400.

Corsair is at the top of their game releasing memory that keeps significantly outperforming the last. I notice that in the PDF they say that you can only run two sticks of this memory at CAS 2.5, but again they are being too humble as I was able to do CAS 2 with both sticks at the same time. Possibly not all boards are capable of supporting this speed. With enough voltage and a good motherboard you can easily do 400 MHz at CAS 2 with two sticks of memory.

Then along comes Extreme Overclocking with their look at GEIL's 512MB PC3500 DDR433 RAM.

GEIL recently released their PC3500 modules in the US. They are designed to run at 433mhz and use 5ns chips. None of the other major manufacturers have produced memory modules rated at this speed, so GEIL is the first to release PC3500. Will it run at the claimed speed, and how fast will it overclock to? Read the review to find out!
