Noticed (without overclocks) that my Memory Temperature hits 106C while randomly gaming, is this enough to be concerned with on a FE - RTX 3090 card?
"104C is still crazy, crazy hot. This article from September sheds some light on what an acceptable/safe temperature might be:"
For reference, Micron rates its GDDR5, GDDR5X and GDDR6 memory chips with a Maximum Junction Temperature (TJ Max or Tjunction Max) of 100C (degrees Celsius). The typical recommended operating temperatures ranges between 0C to 95C. The reading materials on Micron's GDDR6X don't reveal the TJ Max for the new memory chips so there's still a bit of mystery to the topic. According to Igor, the general consent is around 120C before the GDDR6X chips suffer damage. This would mean that the Tjunction value should be set at 105C or up to 110C.

put a noctua fan ont he back of the card and the memory still hot:

i understand those and seen the video before, but i want to know if the temp is actually typical and expected for FE cards or if my card is way outside the range?

As jay stated in the video nvidia's use of their sub standard white thermal pads is a joke your card is overheating like the majority of all the 3080ti's and 3090's with ram chips on the rear of the card. No consumer electronics should run over 100°c.

Every 3000 series FE model is absolute rubbish as far as VRAM cooling goes. So yes, it's within the expected range of being terrible.

That's why ekwb seems to have focused all their new blocks on Fe cards I guess.

Yes it's too hot.
You readily vaporize water over 100°C (212°F)

You need to repad to fix that.
Thermalright TFX (full spread) on the core.
Follow this template for Gelid extremes for the front side. (one pack 1.5mm, one pack 2mm)
Backside, use Gelid Extreme OR Gelid ultimate 1.5mm (you'll need two packs).

My Gigabyte 3090, stays easily at 70-80 °C on gaming, barely using 4GB of VRAM. But on deep learning with all VRAM employed and it becomes an oven getting near 90-110 °C after 30-90 minutes of training c: I've read some post on s1 reducing the temps by using fans and heatsinks on the backplate... I should try this.
Edit: My VRAM temps are usally about 10 to 20 °C higher than the GPU temp itself, according to OHM.

I believe the actually rating is up to 105 °C for GDDR6X You can find it on Micron website. Personally over a 100 °C is a real concern for longevity as I noted in my RTX 3070 Ti, RTX 3080 and RTX 3080 Ti in the review coverage I have done.
Slap a waterblock on it, or fix the thermal pads yourself. Who knows how long it will last. GDDR6X has built in ECC so small errors will not pop up or crash the system, but it will give you a performance dip. if the game is memory bandwidth hungry.

The temp rating for GDDR6X is Tcase, while the sensor is reporting Tjunction. Tjunction is around 15C hotter, that means GDDR6X can operate at full speed up to 110C Tjunction (correspond to 95C Tcase), passing 110C Tjunction it will thermal throttle and risk of degradation at 120C (Tjunction)

Hmm the date sheet suggests 95°C Tcase and 105 °C for the Tj. That would be 10°C not 15°C above.
If I had these expensive card, I should be able to afford the best Thermal pads. That's Fujipoly 17W m/k as used on both my Nano cards. Be aware once the pads are fitted never take it apart, It's forever & permanent. Taking the card apart will damage the pads..

Data sheet is quoting Tcase for both temp, 95C before thermal throttle and 105C before degradation (110C/120C for Tjunction)
Nvidia set 110C Tjunction as the thermal throttling point in BIOS, at 104C Tjunction the fans are commanded to max speed I think.
But yeah I would rather not see VRAM reach boiling temp at all, who knows the BGA on VRAM might just fail due to high thermal swing (happened to Turing already)

Could it be possible to underclock(/undervolt?) GPU memory so it reduces temps on it? has anybody tried ever?
Yes under intensive workload that stress the memory (DL or mining), it's better to underclock the memory, reducing the power limit and increasing fan speeds as much as you can handle help too.

It's become such a problem with these cards there has been an influx of aftermarket backplates now, personally I would take a look, Many can be had extremely cheap compared to the cost of the cards.
Replace the junk Nvidia pads for gelid or some other quality product and slap some form of cooling backplate on it should cost you less than $60 for the lot which is nothing if you had to replace the whole card if it went up in smoke.

i got it down to a max of 100C so far just be repadding the back VRAM only, re-used all the other thermal pads.
still way too hot, or within acceptable operating parameters at least? (dead of winter though)

Been 17 months since 3090 launched and I haven't heard of any large scale VRAM related failure despite many many people mine on their 3090, so i assume you would be fine with VRAM running at 100C.
Though if you want your 3090 to live 5+ years then maybe try to keep VRAM temp below 90C.

Been 17 months since 3090 launched and I haven't heard of any large scale VRAM related failure despite many many people mine on their 3090, so i assume you would be fine with VRAM running at 100C.
Though if you want your 3090 to live 5+ years then maybe try to keep VRAM temp below 90C.
5 years would be real extreme, I usually upgrade within 3, so we’ll see. Was incredibly hard to acquire this FE. Lucked out at MSRP via another forum
