Gigabyte has updated their CPU support page for the GA-990FXA-UD7 and with F4 BIOS and above, it will support the AMD Bulldozer range of CPUs. But with this information in hand, we now know the top to bottom clock speeds of the chips. First up we have the FX-4100 which will have a clock speed of 3.6GHz and a 95W requirement and the top of the pile FX-8150 with the same clock speed (double the cores) and a 125W requirement.
As you can see above, the full listing is shown. We're inching closer til the Bulldozer arrives!
