X58a-UD7 DSDT slow down FPS with Cinebench

[Khan]

If I do a DSDT install I get around 22 FPS with cinebench. If I do a DSDT free install I get about 32 FPS. Do not know if it is a DSDT effect or a combination of the GA-X58a-UD7 and XFX ATI 5770 card. Have tested with graphics enabler YES and NO and 32 and 64 bits with same results. I am currently running non DSDT because of this.

Correction on the previous post. It has nothing to do with the DSDT. However doing a DSDT install and installing NullCPUPowerManagement got me back to about 32 FPS with cinebench. Any explanation is more than welcome.
