Looking at Krams screenshots v mine, i use a 4K panel which is wide than is this forum template
The forum will downsize it to fit, but when posting it, click on the image and link to the actual image like I do so people can look at it in 4k.

GPU core temp != GDDR temps ty is correct. The gpu core can run at a different cycle rate than memory and hashing is brutal on ram. take those software scans of temps with a grain of salt. modern GDDR memory has advanced ceramic coatings that dissipate heat well at its surface where the sensors are located. But underneath that coating is chips getting stir-fried. much like the Intel core processor temp confusion a few years back when they used paste instead of solder for their lid-caps. sensors completely misread temps because they weren’t capturing the real picture.

What is the conclusion then? Is hwinfo right about temps when mining using stock settings? Or do I have to make sure HWI reads 95c or less so I dont blow my card up while mining?

You will know when your memory is getting too hot as the mining speed will drop drastically. If your mining speed stays consent, then you're not causing a memory throttling issue due to temp.

This is going to be the same deal as when a previous mining bubble burst & the market got flooded with R9 290/290Xs etc a few years ago - so many of those cards are going to have VRAM damage that makes them basically useless from being mined on continuously while the memory chips were borderline overheating all the time.
Used market is going to be a mine field once this bubble bursts.

I got a Sapphire R9 Fury cheap from the market correction and I used that card for quite a while. Bit of beast with the 3 fan cooler and dual 8-pin power. I got the EVGA RTX 2080 when the going was good and no miners buying cards.

Okay, just a thought here, but if that VRAM was really hitting 110 C, and those miners are running their systems 24x7, wouldn't we have seen some fires at this point? That's a crazy high temperature and things might start to become toxic or melt.
I'm not an overclocker, or a miner, but I do have CS. (common sense).

An experienced miner would not run their cards like that as this throttles down the memory and the MH/s plummets. Yes I have seen some cards throttle down on some experienced miner youtuber videos and how they went about fixing the issue, all of them were due to bad thermal pads or in need of thermal pads on the backside between the pcb and backplate. Biggest offenders I've seen were Gigabyte and MSI.

My card doesnt throttle when HWI reports 110C memory temp, but that doesnt mean this isnt bad for the card long term. That's the whole point i see people around making.
Ill keep it on the safe side and cap my temps at 95c until more info comes out of this. Not worth losing my single 1.5k card for mining.

In response to questions among colleagues, for example from the R&D departments, it was unanimously agreed that the maximum temperature Ttot before the start of a possible destruction of the chip should be 120 °C and that Tjunction should probably be set at 105 °C or for the GDDR6X even at 110 °C is specified as the maximum value. https://www.igorslab.de/en/gddr6x-am-limit-ueber-100-grad-bei-der-geforce-rtx-3080-fe-im-chip-gemessen-2/ this is not gddr4,5 or 6 which had a tj-max of 100c Gddr6x is set at 110 -ttot is 120c it was unanimously agreed that the maximum temperature Ttot before the start of a possible destruction of the chip should be 120 °C ram will throttle at 110c I luv this we all didn't complain when gddr4, 5 and 6 hit tj-max at 100c but we hit shear panic because someone saw 110c and thought arrghhhh they will fry- when Micron moved up the Tjmax 10c micron makes ram that goes to 130c tj-max if they didn't think it would handle it they would have lowered the tj-max and throttle the ram earlier ps: the card is under warranty - what the hell do you think???? "you are never gonna get a replacement if it breaks down??" what? you be first in line over sending one out or putting out for sale - and if they didn't have one(or aren't making any) would probably upgrade you because by law they have to give you something the same or better

Kram36, I know this is a way too late reply, but I just happened upon this forum today. You may have already discovered this a long time ago, but in HWinfo, you're looking in the wrong section. Scroll up to the GPU0 section, right above the section you posted, and look for GPU Memory Junction Temperature, next entry right under GPU temp. That's the reading you're looking for, not the ICX readings. Unfortunately, EVGA doesn't have that particular temp in its ICX section, though I wish it did, that's something I'd love to monitor while in-game.

It's not showing for me, so I did some searching on it. That function only works with 3080/3090 (GDDR6X), not 3070 and below.

How did you cool this down to high 70's? Is it only a fan and the backplate? What thermal pads are you using? Stock?

I only have a EVGA RTX 2080 so I have benchmarked the card with games and there no unplayable games. I know that GDDR6X runs hot. I do not have a RTX 3080 at present so I cannot show game temperatures.
With prices for RTX Ampere I spend time on mining forums to see what is going on and reports of hot RAM lead to miners fixing with with new thermal pads etc. Some miners I know actually regreased the cards before selling them to me, I have been known to buy pairs of cards for SLI/CFX.
I have repaired many video cards for gaming. It seems that mining tends to wreck the thermal material. No big deal as it takes only a few minutes to pop off the screws and squeeze out some MX-4. I do not use pads and MX-4 does work OK on VRAM in cards I have repaired.

I have a cool room 20-22c (68-72f) ish. Its a Noctua NF-A14 iPPC-3000 PWM, Heavy Duty Cooling Fan, 4-Pin, 3000 RPM (140mm, Black) $27.95 running at 2200 rpm blowing on the backplate. Im using stock thermal pads and the 3090 Kingpin is stock. The 360 clc on it does a wonderful job of keeping it cool, but i do have the LN2 bios flashed to normal position for faster fan speeds and higher power and i run the fans at 95%, fan 1 1895 rpm, fan 2 3220 rpm.

If it's hot for crypto, it'll be hot for other examples. This sounds like a problem for any end use that stresses the cards.

Most of these 3000 series cards have bad or cheap thermal pads especialy
Gigabyte i got these to replace the stock pads and they work great...110c down to 76c
https://www.amazon.com/gp..._s00?ie=UTF8&psc=1
I use EVGA who will send any customer thermal pads in request to repair a video card.
