Is there a program to check whether error correcting my 7970 memory is kicking in?

As title really. I'm overclocking the ram on my 7970 and wanna know when the error correcting starts to kick in. I was thinking about comparing fraps frame times - looking out for more or less peaks. Anyone else got any ideas?
 
the only semi official mentions seem to refer to ecc in firepro cards? don't quote me though - all i know is it doesn't seem to affect my scores, so i'm guessing ecc isn't enabled in consumer graphics cards. i've had 3 79xx cards and they all steadily went/go up in performance with each memory clock increase

^^this. With my 7970 I notice an increase in benchmark results with every increase in ram mhz until I push it too far and it crashes

I could have swarn that i read it in reviews of the card, but having a quick look back through some i can't find mention of it.

I'm just trying to get rid of those odd really slow frame times in BF3, maybe i'll just have to wait until the new memory drivers are out.

Edit - i think it's just all GDDR5 that has it

i tried looking up the correlation between gddr5 and ecc before and tbh the link you've shown me is the first i've seen on it. they might be right but then again they might be wrong.

i just remembered ecc takes a certain amount of memory so that you don't get 100% usable ram. ecc requires more ram chips or something, and it reduces performance. it's more expensive as well. to be honest it doesn't sound at all like the kind of thing graphics manufacturers would want on consumer gaming cards that aren't mission critical. also as far as i'm aware the 7000 series cards have the normal amount of ram chips to make up 3gb, and all of it is usable. honestly it's all guessing on my part but it seems unlikely given the evidence
