It's entirely possible. I'm admitted very new to all of this and learned everything in the last few days, so I'm not even sure how you test for memory errors. I did read a couple people mentioning memory errors in boosting the memory clock speed but didn't think to consider that in my testing.

I'll read up on that and report back.

It will be unfortunate in years to come when I upgrade video cards again but am forced to go with DP. I hope they have any glitches sorted out by then. I'm not saying that DP is terrible, but I have seen a fair number of people having issues with DP over the last few years.

Correct me if I'm wrong, but I don't think HDMI beats DVI-D Dual Link for bandwidth, which should have double the bandwidth of DVI-D.

HDMI 1.x no (roughly the same give or take), HDMI 2.0 yes

Even still quality is the same

I'm having difficulty finding utilities that will adequately test my GPU for memory errors. The best I could find was EVGA OC Scanner X v3. There's a blog that lists four other programs but they all seem to be outdated and don't seem like they would properly test the memory. If you could point me to any programs suitable for memory error testing I'd appreciate it.

Anyway, I'm not sure how comprehensive or credible EVGA OC Scanner X is but here are results after running for 15 minutes. I could run it longer but it didn't even seem like it was pushing the card at all so I don't know if it would have found anything.



Edit: I can hardly make out that screen shot when I enlarge it, here's a link to the full size image:

Hwinfo does it, don't know if anything else that actually checks it.

Stress tests don't check memory errors

Myself had issue with Sapphire RX480 Nitro 8gb and I had to request for replacement!

At least the cards are not exploding like some of the GTX 1070/1080's. rolleyes.gif

Any new product can have problems, and there are quite a few P10 models that have some issues. But the reference cards seemed to be rock solid, and most of the 'quality' issues have only been related to expecting higher overclocks.

Ah, didn't realize it was that simple. As you can see in the previous screen shot I conveniently had it open the whole time, and sure enough there are errors.



Would you basically not run at a memory clock speed that is giving you any errors at all? Or is there an acceptable threshold where if you aren't noticing anything in game it's fine?

Edit: Silly me, I thought the number of current errors was a continuous constant reading but I see that it's a total from when you started the sensors. I guess the second question doesn't really make any sense now. Edit 2: Alright, it seems it is the last total count of errors found in one instance I guess? Looking at the graph I see I'll have 143 errors, then another moment where it's 53. In any case I guess I'll start playing with the memory clock and trying to get the errors to go away.

And it also looks like the peak GPU voltage is a little higher than the 1.162V it's set at, but I'm guessing that's not uncommon?

well crap, im impressed, thats a really good error count for that clock and you should be ok to run it if you want but go ahead and lower it if you want 0 errors.
