AmdZone published a review of dual-channel PC3200 DDR modules from five different manufacturers (Corsair, Crucial, GeIL, Mushkin and OCZ).
It seems that Corsair has difficulties with several Nforce 2 BIOSes; sometimes you need a BIOS update to enable higher frequencies than 400 MHz:
“While stomping the competition at 400 MHz, I can not recommend their PC3200 memory until the majority of nForce 2 motherboards come with fixed BIOSes flashed by the manufacturers.”
Apart from this problem, they discovered that Mushkin was the best performer, and OCZ offered the best price/performance ratio.
