Extreme Overclocking with AMD’s Dragon Platform – Phenom II x4 955

Posted on May 13, 2009 2:30 PM by Rob Williams

AMD has sent us along a fresh “Unprocessed” video, which takes a look at extreme overclocking with their current high-end Dragon platform. The video includes their brand-new Phenom II 955 CPU (which we are still in the process of working on content for – I promise) and also Gigabyte’s MA790FXT-UD5P… another motherboard we have en route and hope to put to the test very soon.

Overclocker Chew* puts all the hardware to the test, and of course LN2 is brought into the mix, to achieve some incredible scores… and even break a few world records. For 3D Mark 06, he was able to hit 32,281 for dual HD 4890’s, and 28,831 for dual HD 4850’s. For DDR3, he hit DDR3-1636 6-6-6-16 (I want this!), and for CPU overclocking, he hit 4.5GHz on air (wow) and 6.4GHz on LN2. Not bad, not bad at all. More results can be found in the video, so keep an eye out for ’em.

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.
