Which build?

They just released a new BIOS (FCA), check it out. If it doesn't work, contact Gigabyte and tell them that memory remapping is not working well on Windows 7 64-bit. They need to provide BIOS update to solve this issue.

I had the same issue with Vista, so I pulled one chip and moved it to my HTPC and installed Vista 32-bit. I don't see the benefits of 64-bit yet, even simple stuff like Adobe Flash doesn't support 64-bit. I guess Windows 7 is going to be the same, Microsoft has to pull the plug on 32-bit and force everyone to focus on 64-bit.

I have latest bios for my motherboard. If situation will happen again i will ask gigabyte.

no gigabyte mobo has mem remap option in BIOS, I guess it's enabled by default

Enter the BIOS and press Ctrl + F1 and see if you get to the "advanced" part of the BIOS, it might be there.
