Overclocking Guru Chew* relentlessly overclocks “Dragon Technology” with stock AMD Phenom II X4 955 processors on GIGABYTE GA-MA790FXT-UD5P, and recently published his results spanning air, phase, dry ice, and liquid nitrogen. He pushes DDR3 and the extraordinary north bridge of the 955 to the limit. The stock 955 has tremendous north bridge scaling potential and achieved overclocks at significantly lower voltages than prior processor models. The achievement was accomplished on GIGABYTE GA-MA790FX-UD5P and GA-MA790FXT-UD5P, featuring “Ultra Durable 3 Technology:” the industry's first motherboard design with 2 ounces copper layers to tremendously enhance stability and performance for overclocking. Brian was able to break 3DMark06 records for dual Radeon HD 4850’s and 4890’s in the Dual Crossfire configuration supported by these two motherboards.

Gigabyte sure has stepped up recently!
May have to go back to Gigabyte, ASUS has let me down abit. 2 of the last 5 ASUS mobo's I bought or recommended have failed recently!
