Hi all, been tearing my hair out all day trying to get my pc to read the full 8gb of ram I installed. Both in BIOS and CPUZ it detects both sticks but only has 4096mb available memory in total.

I have checked the msconfig memory limit and it is disabled. I have reset bios settings to default. I have have tried each stick individually in both slots. I have cleared the power. I have even gone as far as checking to see if the heatsink wasn't on too tightly (after hours of research,these are the depths I reached).

It was working at one point, showing the full 8gb but I recently noticed a drop in performance and saw that it only had access to 4gb.

My setup is:

MSI FM2-A75MA-E35 Motherboard
AMD A8-5600K APU
CORSAIR Vengeance DDR3-1333 4GB RAM
Transcend DDR3-1333 4GB RAM
R9 280X ATI 3GB Graphics card
Running Windows 8.1

Any suggestions? I don't know if this matters but CPUZ is also showing it as single channel.?

Thanks

Are you running the 64-bit version of Windows 8.1?

Having tried each stick individually, did both of them function normally?

Have you tried each stick individually in all motherboard slots and also tried different slot combinations (e.g. Slots 1 & 2, Slots 1 & 3, Slots 1 & 4)?

If you're running a 64-bit OS and both sticks are functioning normally you may be looking at a motherboard issue. To be sure this isn't an OS issue, install Windows (or even Linux if you're familiar with any of the distros) on another drive/partition that you can boot from and check if it detects the full 8GB.

Thank you all so much mych for the speedy responses. Not sure how RMA works as it is a pretty old board by now and I'm guessing it has to be within warranty period? Think it'll work if I just buy one single 8gb ram stick? Or is it best to just replace the board?

Yeah it would need to be under warranty for RMA. I noticed there are a fair number of used Hudson boards on the various for sale sites though so it's should be an inexpensive replacement.
Newegg has a refurb for 35 bucks including shipping that would be a direct replacement for yours. Don't forget to apply new thermal grease when you reinstall the CPU.

A straight exchange for a board with the same chipset will give you the least amount of problems such that you won't need to reinstall the OS etc.

So just for future reference for others, I got it working. I reset my bios again (I must not have done it right the first time). I'm guessing my attempts at oc'ing the last time changed something it shouldnt have but it is working now. Thanks again to everyone for your input.
