Problem: Windows is only using half of my RAM. The BIOS also in certain sections only recognizes half of it too, but in others it's fine. Using HWiNFO I can see all 4 sticks of my ram, I just can't figure out why any of this happens.
It hasn't always been this way, but this has been going on for at least half a year now because I can't solve it. From research I've done (to which I never got a conclusion), I think it has something to do with CPU overclocking.
Another issue I have is that the when raising the ram frequency too high (not to it's listed spec) I have to do a bios reset because the PC won't boot. My ram is rated for 3733 or something like that. Help with either issue would be greatly appreciated, though I'm more concerned about how half of the RAM isn't usable.
I have already tried checking msconfig for a memory limit (this wouldn't cause the BIOS to not recognize half of it though I think), and reseating the ram slots in different order, as well as testing each one. They all work. The PC is almost a year old.
