Well, funny you said that. I just did that test. And I got back to 12GB Physical / 8GB usable. So I kept the m"bad" module out and switched up the other modules to all logical places. Everything was ok, but still only 8GB was showing in the BIOS. The last time I said 4GB was usable, both the A and C (1-3) channels were blanked in the BIOS.
So anyway, I pulled out a stick of "good" RAM and inserted the so called "bad" RAM, and then the BIOS showed *GB again, with the C channel still blank.
I'm at a loss here. Sometimes it works and sometimes it doesn't. This time I'm getting a much faster load speed into windows and a solid 8GB usable, but the C channel is still not counting off.
It could be anything, bad mem controller, bad BIOS, bad MB. The only thing to do now is isolate. But that means buying new hardware, and right now, I can't afford it.
I talked to an Intel tech rep and he said to talk with Gigabyte first. So I have a tech email to Gigabyte. I also have one at OCZ. They said to check the RAM individually, which I have done three times now.
Like I said, this one has me scratching my head. Reminds me of old school trouble shooting when a bad CPU or board, or RAM was more likely to go bad than today's hardware
