So I've got 16Gb of RAM in two sticks of 8Gb, and half of it seems to be unusable. My BIOS can see both sticks, and confirms the size, speed etc - but insists that only 8Gb is available. Windows similarly can see 16Gb total, but claims that 8Gb is "Hardware Reserved".
Haven't really found any clues as to what could be reserving eight gigs of memory. At the moment it seems possibly an issue with the BIOS - I tried updating it to the most recent version available, without much luck. Does anyone have any insight as to what might be going on here?
Here are some specs:
Mobo is a Sabertooth 990fx r2.0, with a Phenom II X6 1100T processor (3.3GHz, 6-core) and a GeForce GTX 560 Ti graphics card.
The RAM sticks themselves are a pair of 8 gig DDR3 Corsair sticks - managed to find the same ones on the interwebs, so I'll link them to make sure I'm not missing any info: http://www.scan.co.uk/products/16gb-(2x8gb)-corsair-ddr3-xms3-pc3-10666-(1333)-non-ecc-unbuffered-cas-9-9-9-24-15v
They're currently installed into slots 1 and 3, with slots 0 and 2 being empty.
Anyway, if any of yall could give a hint as to what might be causing this, it'd be appreciated ;D
