Ga-ma790fx-ds5 help!
I need some help with this board. I cannot get the board to clock my RAM at 1066. Here are some of my basic specs:
GA-MA790FX-DS5 ***BIOS REV F5***
AMD Phenom 9550 2.2GHz
Corsair CM2X1024-8500C5D
The RAM is supposed to run at 5-5-5-15 at 2.1v for 1066MHz. The computer gives me a long beep and then reverts to 800MHz and 5-5-5-18. This happens with both sticks of RAM installed and individually installed. I have been successful at 800MHz with no errors in Memtest or Microsoft's RAM stress test. I really want to run this RAM at 1066. I contacted Gigabyte and they said it was my RAM. Corsair gave me the following advice:
__________________________________________________ ____
Set Memory Clock: Manual Memory Clock: DDR 1066 (although the manual only states that it supports up to DDR 800)
DRAM Configuration DDRII Timing Items: Manual
CAS# Latency: 5
1T/2T Command Timing: 2T
Row Cycle Time: 24
RAS to CAS R/W Delay: 5T
Row Precharge Time: 5T
Minimum RAS Active Time: 15T
DDR2 Voltage Control: +0.3v
Chipset Voltage Control: You may want to try increasing this in small increments up to about 1.45-1.5v to see if you are being limited by the chipset, although this is technically overclocking your motherboard.

I have taken these steps with no success. I'm open for suggestions and help!
