Got the 2x512 Corsair value select (CAS 2.5). Works great with games, but have to set the memory speed to 400 with Utility manager otherwise at startup is runs at 333 speed. There doesn't seem to be any BIOS setting for mem bus speed. Running F6 version on the BIOS. Overclocking is not great, still only 210FSB, only 5%, and it shows on AquaMark, so I know it is working. Also, the Antec Aria case is the wrong case for this processor. The CPU heats to 120F while gaming at stock clock speeds, not dangerous, but it will run 111-115 with the sides removed. I'm thinking of moving it to my classic CoolerMaster case.
