I just picked up a black edition and the memory temp junction is not what I expected.
With ambient temps of 74-75 fahrenheit the memory junction temps are reported as around 84-86c at load. It's worse if I have the card in a coolermaster vertical riser in which case it hits 90c. Fans spun at 75% in both scenarios.
I was expecting to be down into the 70s with this card. I've seen at least one other person has called into evga to mention higher than expected temps on the memory.
Are my expectations out of line with reality here or is there some sort of issue going on possibly with QC here?

I don't think I've seen air-cooled memory temps on any of the big cards hit as low as the 70's (peak) under load. the 3090's hit 100C regularly if you don't do something about the cooling on the back of the card. There are some quite deep threads about it in this forum.
The positive thing about the 3090ti is that all the memory is now on the front due to the larger modules than where available when 3090 launched. So I would expect temperatures similar to 3080ti. I think the memory junction temp or memory hot spot (I can't remember exactly what they call it in HWiNFO64) gets to about 80°C max on my hybrid 3080ti. it's sometimes in the high 70's gaming, but I've seen it hit 82°C as well.

It is genuinely not an issue at that temperature. If you want it reduced, new pads and/or copper shims will reduce it some.

I’m not sure what scenario you were using for testing by my memory temps were mid 60s on my 3090 Ti Ultra.
The cooler is far better on the 90 Ti so no I would not expect similar temps to a 80 Ti. The vapor chamber keeps things nice and cool now. Maybe you have poor thermal pad placement or contact.

Thanks for clarifying that. I just expected it to be better than the non-ti 3090 because that has modules on the back that aren't cooled as well. 3080ti is the next biggest (primarily from a thermal perspective) card with all the memory on the front, so I went with that. I'm glad someone else with a 3090 ti chimed in.

With the card both on it's side or in a vertical riser inside a case with good air flow and ambient temps in the mid 70s fahrenheit. 86c is as low as it gets. Not even close to the mid 60s. As I mentioned earlier I've seen another complaint about the same problem. I guess I need to call evga and find out what they want to do about this.

there's nothing wrong with the temps of GDDR6X at ~85C. totally normal and well within spec.

To add a little more data to the picture here I am testing the memory junction temps with t-rex ethereum miner. This targets the memory for stress testing. This is where I'm seeing temps of around 85-86c, and 90c when the card is in the vertical gpu riser. Numbers for this stuff are all over the place. I've watched gamersnexus review. https://www.youtube.com/watch?v=HWS9G2WT42Q&t=14s07:38 and 12:26. His testing was done on an open-air bench and achieved 60s. Talon states he was seeing 60s. My card is in a case and I would expect a healthy 10c increase over an open-air scenario, which is still quite a bit under what I'm getting here. I called evga and they are sticking with the "it's in spec" and is fine. I can't argue that, it most definitely is not in danger of melting here. But when your result kinda sucks compared to others, and by a pretty big degree, it does make you say hmm...

That's not out of line at all for an air cooled card .

So you're hammering the card's memory controller harder than any game will ever hit it and you're confused why your temps are higher than normal? Gamersnexus ISN'T testing the card with ETH mining, they test in games and real world scenarios like rendering, neither of which abuse the memory like mining ETH does not even close. Furthermore the junction temps are just the hottest part of the memory NOT your average and are not what your temps are considered as. Same way the GPU hotspot is not considered what your GPU temperature is reported as. It's just a hotspot and is very normal and expected behavior. Considering your far more abusive "test" and your temps still staying WELL WITHIN spec I'd say you are fine.

What scenario were you using for your testing?

I'll look into this further since it does bring up a valid point IMO. Some of the results I've seen are possibly not stress testing the memory in the same way or to the same extent that my scenario does. I am seeing lower values vs. the 3090 FTW3 Ultra I had, in the same scenario, just not to the degree (hah!) that I was hoping for here.

I would debate the idea that mining isn't a 'real world' scenario. It isn't the only use-case I'm applying to the card, I play a lot of BF2042 with it too. It's dual-use. This is getting beyond the scope of the thread here though. I understand where it is designed to throttle and I'm 20c or more off of that point so there is no "problem" in that sense.

There is no doubt or confusion that mining ETH places a wholly unrealistic load on the memory. It's not even close to real world applications like gaming and rendering. While sure mining is a "real" use for a card, they aren't tested in nor designed in this capacity and therefore is an irrelevant metric to base your numbers on.
