I am using a Phenom II system (790FX with SB750). When I enable C1E in the bios, Crystaldiskmark measures 9MB/s 4k write and the same for 4k read speeds. If I disable C1E, then it goes up to 20MB/s read and 50MB/s write, which is in line with what other people post for the same drive.
Why would C1E cause this? I run CnQ on the same system and it doesn't affect the drives performance.
