Radeon 5970 Overclocking: The VRM Temperature Bottleneck

[safan80]

It runs over 80c at stock, thats thermal problems as far as i'm concerned.



Considering nobody here is mentioning how ambient temperatures or fan speed play a role in stability (other than the article) this thread is pretty much moot..

both my factory OCed 285s get over 80C, and that's with the cooler at 100%. I bet if people were to run the 5970 cooler at 90% it would manage to stay below 80C without problems at stock. The thing is most don't want to do take advantage of the ATI cooling system by raising the fan speed. the heat and VRM issue is not just an ATI problem it's an Nvidia one also.

It took AMD a full 13 months (even w/ GDDR5/DX10.1/DX11) after the 295 was launched to catch up with it. Let me go ahead and avoid the fanboy comment by noting the 295 was the fastest video card in the world up until the 5970, me owning one has nothing to do with this fact.

So it appears to me NVIDIA was sticking with a very solid design and using it as a placeholder until the GT300 is ready for the masses, seems like a very good idea to me instead of rushing a product simply for profits in a non-competitive market (DX11). If any ATI fan boys would read about the GT300/Fermi they would see it is a completely new approach to GPUs and is by far more innovative than anything ATI has done in the last few years.

For my resolution the GTX 295 is a joke the stock cooler can barely keep it cool.
the GTX295 is gtx 260 based, if Nvidia's cooler had enough power if would been 285 based like the Mars. The Mars are overheating in a lot of cases. The only reason the 5970 does not come standard at the 5870 level is because they were trying to keep the video below 300 watts.

With all that said Nvidia between now and the 295 should been finished with Fermi. They went to the point of showing completely fake Fermi cards, and yes they've changed the focus of Fermi to avoid competing with ATI because Nvidia's Fermi can not compete.

Marketing BS is the only Nvidia has going for themselves at the moment, and for those that believe it I hope you get what you pay for.
