AsRock , the motherboard is a B3 revision . I need to take this R9 to a friend's tho , maybe it has some issues with older motherboards . Toothless , i already talked to the guys at XFX and they told me to contact the reseller in order to get a new bios
))) . The R9 wasn't limiting my memory , it was the same with any card i used after the Sabertooth started to have this issue . Now , i don't know if it was the R9 or not , but troubles started after i've replaced the HD5870 with the R9 and reinstalled Windows . AsRock , i can't return the card to Newegg , it's been purchased 2 or 3 months ago , icba to check my mail now , but i've got it on Christmas . The purchase date was 2 months older . I'm gonna sell it for nothing , maybe someone has use of the cooling system .
Goodness, sounds like ASUS is just full of issues as of late..
I'd search around for any fixes to your GPU before it (could) wreck your board. I've never heard of GPUs limiting memory THOUGH are you sure your 4GB that was missing wasn't going to the GPU? Weird question yes but I'm wondering if shared memory took it over.
That was i thought from the start, but i see no reason why a 3 GB card would take 4 Gb more from the physical memory . I've even removed the card and reinstalled Windows with a Nvidia card on . Same issues , memory missing , memory is fine , cpu is fine , Sabertooth is dead , that is .
I did a 3Dmark Vantage test on the "new" rig . Results are the same as with the Sabertooth , but i just recalled that on Sabertooth , Vantage was crashing at the cpu test . It worked with the new board . UEFI still doesn't work , but i assume there is a incompatiblity between R9 and Sandy Bridge chipset , regarding the PCI-ex 3.0 . Here's the results
