    Just now playing a session of Doom Eternal, maxed with RT, etc. at 3840x1600, DLSS off (this is mostly 130-144hz anyway, don't need DLSS), 400W gaming profile, Auto/stock fan profile on air, see below.

    Basically, hits 86°C memory temp, where just before my session, it was sitting around 90°C after mining for 20 hours on a 230w profile and fixed 80% fan speed.

    This is in a closed case. I chose this as an example of a game that gets the memory junction temps closest to what mining does.

    Most other games are in the 70's to low 80's.

    I used to get those performance metrics before I applied better stuff to the memory when I put the evga liquid kit so much better and cooler with a higher hash rate even during gaming

    Was going to buy a normal 3080ti and then a water cooling kit like I did with my 2080ti and now regret not doing it........the gpu is cool and in normal gaming memory is 70C max

    Brilliant idea, I hadn’t thought of using DLSS at native res as a super AA technique, and didn’t realise people were using it with DSR already to achieve the same thing.

    Definitely gonna play with this in DLSS titles where I already have excess headroom (F1 2021 for instance).

    Anyone here put themeral pads on the backplate of a 3070 and replaced existing themeral pads?
    I have a Gigabyte 3070 OC which does look to have any themeral pads attached to the backplate

    Edit: I am not experiencing overheating issues, max I have seen my GPU hit was 62-65 degrees while stress testing

    Haha..., I'm nowhere near as bad as some of the other guys, but thanks for the compliment.

    Don't know if you have done this yet, but in case you want to look at the inside of your card before you crack it open...

    I tore mine down and took a few pictures and did a bit of a write up. The new thermal pads certainly helped my temps (especially after I worked out I'd missed one and corrected it lol).

    Rated to 110*c before throttling, so i wouldn't be concerned tbh. Esp since FurMark is so detached from the real world.

    Early model 3070's are the best cards in the world to mine with outside of a 3060Ti early model. (Both have same performance in mining or very close) The 3070 was the most plentiful seen in shops. I wish I had a dozen 3070's. I only have one. Mine sits at 511 Eff/Watt and barely puts out any heat.

    Their memory chips are not on the backside of the board like half of the 3090's are. There really is no need to cool the backplate of a 3070.

    I decided to teardown my Aorus Xtreme 3080 yesterday, and found my original repadding with thermalright 12.8w/mk wasn't done very well - basically at the time, rather than replacing with the factory 2.0mm thickness I had gone with 1.5mm at the time because initially, it was causing issues with GPU contact.

    However, its very evident that some of the chips were only lightly contacting the mem pads (you can tell with the thermalright pads as they have a very shallow criss cross pattern, and alot of it was still there meaning the contact was poor).

    I redid them and now even mining it only reaches 74 to 76°C with fans at whisper quiet setting. In Furmark I got them to 70°C, and likely will be similar in Doom Eternal. Now I can run +1500mhz on the memory for mining. Given out of the box I could hardly hold +1300mhz, this is quite a gain overall.

    That's REALLY good. I now have a rear waterblock on my 3080 which already had an EK backplate - and it still peaks at 90C while mining and around 86-88C average. That is of course a totally safe temp, and the backplate has gone from scorching hot to barely warm to the touch.... but should be much lower looking at your results.

    I think the EK pads might be pretty budget - I have Thermal Grizzly replacements here ready to go so I might just have to accelerate the change over. Another loop drain!!!

    How do you test for mem stability when mining? I run at 1300 with no invalid shares, but haven't tried pushing higher. ~101 mh/s

    That's it, just leave the miner running, keep an eye on the hashrate and make sure there's no invalid shares.

    I don't know about what you've experienced so far, but I find there's a very narrow window for the RTX 3080's when mining, where essentially if you cross a certain point where instability creeps in, you get some invalid shares, but creep slightly above that, say, +50mhz above that and bam it can cause the miner to crash and quite often the entire system to reboot.

    Just seems like a knife's edge for the GDDR6X. On the other hand, my 3070's and 3060ti's will just have invalid shares until the cows come home without crashing anything, which becomes more manageable when pushing the limits.

    My FTW3 Ultra was fantastic out of the box, +1700mhz with ease, 104.3mh/s purred along. It really comes down to the thermal transfer properties of the pads. I guess the Thermalright 12.8 w/mK ones do indeed work very well.

    For what it's worth, an identical product is being sold under "Zezzio" and "BCI" brand now as well. I've compared it side by side, and it's the same product, and my results seem identical too.

    I think they're just incorrect listings on storefronts. As far as I can tell there is no such thing as an LHR 3090.

    I thought they were not making LHR 3090s? That's sh!t ...

    :(

    Edit just saw the reply above

    :)

    Actually I thought the Gainwards with that cooler were LHR, maybe all but the 3090?

    :)
