When your system is POST'ing, how much RAM does it say is installed?

Press tab on the Gigabyte splash screen to see the POST details.

Also, if you go into task manager, then on the performance tab, how much does it say for the total physical memory installed?

I had an issue a while back where my system was only seeing 4GB of RAM instead of 6GB, both the Windows Basic Info and CPUZ said that I had 6GB, but when I checked the BIOS, POST info, and Performance tab in Task Manager, they all reported only 4GB...

If you update to the very latest version of CPUZ (1.52.2) it will tell you if your system is only seeing 4GB..
I updated to the latest CPU-Z and I still have the same issue. Both the post and task manager see 6gb, but I still can't see the spd tab in slot 5. All the sticks are clean in memtest too. I guess this weekend I'll try swapping the slots of two of them and see if I encounter the same issue.
