8gb ram installed. windows says only 3.96 is useable?? - SOLVED - Page 4

post #31 of 56
Hmm. I looked over the manual and didn't see any memory mapping option either. The memory compatibility sheet noted that only one DIMM per channel is supported for 1866Mhz mem and higher using an AM3+ CPU.

Something that worked right before and wasn't hurt is unlikely to not work afterwards, to me it's clearly the CPU.

I'm sure someone already posted this, but have you tested each ram stick along with every DIMM?

- Use Ram stick A in all four ram slots and confirm it working
- Use Ram stick B in all four ram slots and confirm it working

If you have an issue with a specific slot, it could be CPU or board related. If one stick runs fine in every slot and the other doesn't, then its definitely the ram.

Well it is definetly only running a single channel. It cant be post with one stick either..

Tried every combo of slots. No dice.

I would, but I fear it will get rejected by newegg. I mean, its hardly obvious. But a couple of pins might be off by a degree or two. And their is a tiny mark on the corner of the lid and the corner of the pcb fractured slightly.

Do you mean as in group A and B? I already tried putting each stick in their own channel and I cant post. Cant post with a single stick either. The only way I can boot is with them in like colored slots. Another thing too, by default, my mobo downclocks the ram to 1600, 11,11,11,28. Even at those speeds it still doesnt work.

Sounds like a motherboard issue.
I had an Asus P7H55M-USB3 pull this on me. 6GB detected in BIOS (2-1-2-1) but windows said 3.25GB useable even though I was on 64 bit Professional.

Okay. So surely at this point it either must be the motherboard or the cpu? If its the cpu, I guess I could try to RMA it, but if its rejected, I dont know what to do other than buy a bran new one?

What was your solution? I have exausted everything I have found online.

Got the board RMAed. Though that was one hell of a problematic board.

I got a new one back, and the worst thing about it, is that it now has another set of problems.

Found another thread a bit down with a guy with the same issue. He said his turned out be bent cpu pins. I guess I will pull mine again and take my jewlers magnifying goggles to make sure they are as straight as I can make them.

I almost want to just put my trusty lga775/e6600 back in and call it a day and just sell all this off. So frustrating. Never had any issues with my old build.

chances are its the motherboard, caused a short when you first assembled it or reassembled it back again into the case. had the same exact problem, after many tests i was lead to believe it was the motherboard problem .. g o on cpu z and under memory see if it notices if it is single or dual channel if its single then 99.99% sure its the motherboard

It says single...

Okay, I am going to cancel my rma for the ram if possible. If not, I will just eat the 8 bucks for the shipping label.

I guess I might as well RMA the mobo first. And if that doesnt fix it, I will try the processor. If they reject it.. Well I guess I will sell it here or on ebay for a steep discount and buy another. I am sure at this point it must be hardware. I have tried to many things for it to be software. frown.gif
