Powercolor 7950 High Temps

[chopsbit]

I'm going to use my Powercolor 7950 for some casual Bitcoin mining when I'm not gaming, however when I gave it a try this evening the GPU temp spiked to 98C and hovered there with the fans running at 100%.

Using MSI afterburner I've set the following values, however it still spikes to this high temp:

Core Clock = 925 (This is the card default)
Memory Clock = 625 (Card default was 1250)


I'm using CGMiner v2.11.3 with the default settings, and I've just upgraded to Catalyst Control centre 13.1

Has anyone got this card or have any ideas why this temp would spike so high?


Thanks

You're sure you set the memory clock TO 625 and not +625? Afterburner goes by displacement so like +x or -x not setting exact values.

I think so, this is what I have in Afterburner and also in Caps Viewer:

Do these look correct?

Hmm, that's really odd. Possibly faulty card. Does it give same high temps in gaming / stress testing (like furmark)? If so that's not what it should be and you should probably RMA.

thanks for the reply, I've not used Furmark before but just gave it a go and temps maxed out at 72C with 100% GPU load.

this is also after setting the memory clock back to its default of 1250 which seems more reasonable to me. Gaming has always been fine, just seems to be bitcoin mining that causes the temps to spike!

Anyone have any suggestions, could it just be this card doesn't support bitcoin and I should just stick to gaming with it, or could it be some driver issue with the version of CGMiner I'm using?
