Trying to get the most out of my memory.

[zxcymn]

I ran CPU-Z and noticed my memory was performing less than it could be, and I'd like to get the most I can out of it but the manual configuration confuses me.

Motherboard: ASUS M3N72-D
Memory: F2-8500CL5D-4GBPK
CPU: AMD Phenom X4 9750

My motherboard can support 5-5-5-15 1066, but CPU-Z said they're running at the following:

DC Mode: Ganged
NB Frequency: 1800 MHz
DRAM Frequency: 400 MHz
FSB:DRAM: 1:2

CL:   5
tRCD: 5
tRP:  5
tRAS: 18
tRC:  24
CR:   2T

I took a look at the settings in the BIOS and everything is set to Auto. Can anyone help me configure the settings so I can go the most I can out of them? Here's a picture of the available options: link

DRAM Frequency should be 533MHz.

Make sure DRAM Voltage is 2.10V

Thank you

Ok, I did that (the voltage only gave me options and the closest one was 2.08) and now CPU-Z says my DRAM Frequency went from 400 to 266.7. It's now running at:

DC Mode: Ganged
NB Frequency: 1800 MHz
DRAM Frequency: 266.7 MHz
FSB:DRAM: 3:4

CL:   5
tRCD: 4
tRP:  4
tRAS: 18
tRC:  16
CR:   2T

Did it get worse?
