Hello, I have recently installed an AMD Phenom X6 1090T from another X6 (It was a lower model, I forget at the moment), but after I installed it, I noticed that my RAM had been cut in half, from 8 Gigs to 4. I checked if my 4X2 sticks were in place, and after removing them and placing them back in, there was no difference. Here are my specs:

CPU: AMD Phenom II X6 1090T
RAM: 8.00GB Dual-Channel DDR3 @ 669MHz (9-9-9-24)
Motherboard: Gigabyte Technology Co., Ltd. GA-890GPA-UD3H (Socket M2) Rev.2
GPU: 2048MB NVIDIA GeForce GT 640 (EVGA)
HDD: 298GB Western Digital WDC WD3200AVVS-63L2B0

If anyone could give me any ideas, that would be greatly appreciated.

Thanks!

Nope. I have 64 bit Windows 7 Ultimate. My limit should be 64 Gigs of RAM.

-*UPDATE*-
Upon updating my bios and restarting, my computer will not turn on, and signals a memory error (3 continuous beeps). This only happens when I have both sticks in. If I have one stick, it will boot normally.

Now, here's my question: was it a bent CPU pin that's defecting the 2nd memory slot, or was it the motherboard that said "NOPE!" to my new CPU and decided to defect the 2nd slot?

Please answer! :)
