Windows 7 x64
6GB (3x2GB) DDR3 200 PC3 16000 F3-16000CL9T-6GBRH
Intel Core i7- 930 2.8 GHz
Gigabyte X58-UD3R
Thermaltake 775W 80+ Cert PSU

6GB installed 2GB usable
I have been through many other posts about the F3-16000CL9T-6GBRH and X58 UD3R trying to get Windows to recognize all my RAM as usuable.
I already tried msconfig and setting the max memory to 6144MB. Every time I Apply and Enter it gets reset to 2048MB after every time I check it.

I've tried changing my Bios settings through MIT based on posts from here and the G Skill Tech Forums. Nothing seems to correct the problem and I want these to work to what they are capable of.

Does anyone positively know tried and true settings in MIT so that all my RAM can be usable.
If so, please include all the settings I need to change in MIT, so that I can get what I paid for.

Thanks for any help I truly appreciate it.

I was told to do this.

Enable Extreme Memory Profile to Profile 1. Set QPI/VTT Voltage to 1.550V. Then simply find the lowest stable for stability.

I did no changes. I took the Memtest and got all passes with no errors.

Most every x58 board (save eVGA) requires a substantial boost in QPI/VTT to run the G.Skill DDR3 2000 kits with full stability.

QPI/VTT @ 1.55v is a pretty good starting point. You may have to go a little higher, or you might be able to go lower.

On my GSkill kit I can hit up to 1800Mhz with a QPI/VTT of 1.35v
Any frequency above that requires a bump in QPI/VTT to 1.45v
My kit on my board will do DDR3 2000 speeds at 9-9-9-24 3T timings at 1.50v
