I've just bought this http://www.techspot.com/review/120-force3d-radeon-4870/ As you can see it's got an accelero cooler on it so shouldn't get hot at all. Fitted the card, installed drivers etc all fine. Then I thought I'd run a quick 3dmark06 bench to see how it compared to my 4850, It only managed to run for about 15 seconds before VPU recover kicked in. So I loaded ATITool to test for artifacts, lo and behold I get some straight away with standard clocks! This card is factory o/c'd to 770/950 so I thought i'd drop everything down to ATI default settings and try again. It seems to be running ok now, it passes a 3dmark06 run but looking at the temperatures on GPU-z, the MEMIO temp is alarmingly high- at idle it's around 85°C and under load it can climb as high as 120°C! All the while the "main" GPU temperature never ventures above 60°C. Having a look around on here, it looks as though typical MEMIO temps are around 10-20°C above "main" GPU temp. So mine are way off. Looks like the card is duff, am I right?
