I have an issue with my computer, in that it is not reading the entire 3rd channel. (I hope I'm using the right terminology here.)
I have a Gateway FX6803-25. It uses DDR3, triple channel memory, 6 DIMM slots, and supports up to 12gig.
I'm running Windows 7 Home Premium.
I bought 3 new memory sticks, 4gig each. When I put them in and fired up my machine, I found that it only had ~8gig memory.
After doing testing, I found each stick is in fact working and functional. As part of that testing, I put the original 6 sticks back in, and found that my machine was running on 6gigs. I thought, "See, its reading the originals", however, as I was pulling them out, I realized that one of the sticks was actually a 2gig. I look at all of the originals and found that 3 of them were 2gigs, while the other 3 were 1gigs. Realizing that the math wasn't adding up with my original thought, I went back and found that in reality only the first 2 bays (with both physical slots for each bay), were actually in use. 2gig stick + 1gig stick, x2 bays, comes out to 6gigs... To top it all off, the original spec for the machine was 9gigs, but I was only getting 6.
I looked here for several solutions, and in the process found CPU-Z. I installed that and ran it. To my surprise, CPU-Z is able to detect and recognize all 3 of my new 4gig stick, in addition to the 3 slots that they are in. Also, when I did a reboot, I noticed that it still shows tri-channel memory (the black screen with blocky white text before the windows splash screen).
Yet, my dxdiag still only shows 8gigs (4gig sticks x2, not the desired 12gigs)
I have tried to explain the situation to the best of my ability. I am also completely baffled. Any help would be appreciated.
