AnandTech have a good article where they review the performance of the premium manufacturers' (Corsair, OCZ, TwinMos, HyperX (Kingston) and Crucial) RAM on the 875/865 chipset series' boards. Although Mushkin and Geil seem a bit conspicuous in their absence, the article is quite informative and will help in making a decision for both ram and board. It also shows that you really DO need quality ram when using either of these chipsets, the cheap junk just doesn't cut it anymore.....
