Need stable config for GA-EP45-UD3P, Q99550, Mushkin XP2 8500

[toxophilite]

I've been unable to arrive at a bios configuration that will POST or boot at 1066 dual channel with the following rig...

Mobo: Gigabyte GA-EP45-UD3P
Rev 1.0
Bios: F6
S/N: 084940007503
CPU: Intel Q9550 2.83ghz
CPU Cooler: MassCool 8WA741 92mm Ball
VGA: SAPPHIRE 100265L Radeon HD 4830
Memory: DDR2 Mushkin 2x2GB XP2 8500 1066 (996619)
PSU: Thermaltake 650w

POSTs/boots/runs stable at 800 dual channel with all bios settings on auto except DRAM voltage set to 2.00v as per mushkin instruction.

Both modules run just fine individually at 1066 in single module, single channel mode with stock/auto +2.0vDRAM settings.

Can anyone give me a complete, explicit listing of bios settings I should use for a stable config from which to start 1066 dual channel?

Just bumping in hopes of some help.

Search in the forum for any thread with recommended settings for 2x2GB of memory.
You'll probably need to set manually MCH Core voltage, tRFC and Static tRead, instead of using auto settings.

Is anybody having success running 2 2 GB sticks (4GB Total) at 1066 mhz on this motherboard? Is anybody with this configuration able to run with default bios settings?
