 |  DUH! News of the Day: Overheating ATI GPU causes downclocking “With the core at 875MHz, the average frame rate was sitting at a fairly constant 115FPS. However after just 40 seconds temperatures exceeded 100 degrees and shortly after this the Radeon HD 5970 overclocking problem presented itself,” wrote the reviewer. The frequency of both cores dropped to just 550MHz, which was a 24% decrease from the stock clock, and the average frame was also reduced to 90FPS, seeing a 22% drop in performance. http://en.expreview.com/2009/11/25/a...ng-issues.html

If you look at Anandtech's breakdown on the topic, seems that one bank of VRM's isn't being cooled by anything other than a strip of metal. Anyone wanting to take advantage of ATI's overclocking claims will need to find a way to cool the VRM's... | |

| yeah that was what I meant, with a double GPU a drop in performance due to thermal throttling, Asus issue was bad GPU cooling , this is VRM's... incredible this

| not incredible at all; it works without issue at stock clocks  the moment you go beyond default, you are on your own

If light overclocking + games is enough to overheat the VRM's, I expect they will be the point of failure pretty early in the card's lifespan. | |
