I have seen this question here and other forums but the reported fixes have not worked for me.
Here's what I have:
Gigabyte X58A-UD3R
Intel I7-930
Corsair XMS3 6 GB
Windows 7 64bit

Windows shows 6 GB of ram with 4 GB usable. I updated the bios to F5 and unchecked the maximum memory box in msconfig. I checked resource monitor and it shows 2050 of memory in Hardware reserved.
I also pulled the cpu and inspected the motherboard, I could not see any bent pins but there was an are of silver in the middle of the motherboard, I did not see a pin there. Hoping there is not a missing pin.

Any Ideas, if you need more information please ask.
Thanks for your help.

Hi newcomer and welcome to the Tom's hardware forum.

Enter to the BIOS and press crtl + F1, with that U can find the option to addressable memory for use the 6GB.

I tried pressing ctrl + f1 but did not get an option for addressable memory. I did figure out the problem though. Memory channel 1 is bad. I tested each stick of memory in channel 1 and it did not boot. I tried memory in only channel3 and only channel 5 and channel 3&5 and they all worked. Looks like a RMA for me.

Which RAM slots are you using? You're supposed to use the white slots on your motherboard. You can verify that in the motherboard owners manual.

I have the memory plugged into slots 1, 3 and 5, which are the white slots.
