Any ideas what is going on? I was running FurMark and getting 30 fps. Then something happened and I was getting 60 fps (3000+ score), and now I'm back to ~30 and 1900 score).

GFX: Gigabyte HD 7950 Windforce 3X.
CPU: 3570K clocked at 4.8 GHz
RAM: GeIL EVO Leggera 8GB.
 
You shouldn't be running Furmark at all :)

A while ago Furmark was identified as a GPU killer, in response both AMD and nvidia added chips to the PCB's to detect Furmark and throttle down when it was used, as a result Furmark scores are all over the place and it no longer stresses the GPU.

Wow, well, thanks very much for the explanation! That clears things up a bit :D

I think the other problem was Furmark showed how much power the cards could really use left to their own devices. This was not good from a sales point of view.
 
No software can kill hardware if the hardware is designed correctly.

I think the primary reason they imposed throttling on Furmark is so that they can push the envelope further without going beyond the artificial TDP limits set for OEM's etc, it also enables them to underdesign the cooling and power circuitry by not having to build it to cope with an absolute worst case scenario (cheaper to build etc).

Any damage that would occur today because of Furmark running at full whack would be down to the reference coolers not being able to adequately cool the GPU and especially the VRM's, even if they were cooled adequately instabilities could arise from the power circuitry not being sufficient for a fully loaded GPU because they now design it to be just good enough to run games.

If most other hardware manufacturers underdesigned their hardware in this way it would probably be exploited by virus developers to cause peoples' computers to crash and general mayhem, I guess the high end GPU market is so small it's not worth bothering.

Furmark push GPU's much harder than any game would, they could design GPU's to handle Furmark as well as games, but at a higher cost to us for higher grade components.

I'm just not willing to pay more money for something just because Furmark goes outside of the original design envelope.

I would rather makers did exactly what they did, making them more expensive just for Furmark is just plain silly.
