Yes, if overclocked too much and not in a well ventilated case.
Even some of the cards that have water blocks fitted are still having this overheat issue on the memory chips.

Wowww.. It's damn serious !
Thanks for the info

I assume the problem will be worse for next 3080Ti / 3070TI

The RTX 3060 Ti and the RTX 3070 use the older GDDR6 memory, so they don't get as hot and is not an issue 99.98% of the time.

The higher spec'd cards use the GDDR6X memory (Double Rate) and need more power to drive them, this is why these RTX 3080 / 90 cards get hot.

Yeah, I got that.
Even a highly cooled custom card like MSI Supprim 3080 would get too hot on mem temps ?

The cards also have their own curves which can not be controlled with AB. NVIDIAs still have temp sensor on memory - just not showing public - so when mem temps get too high, fans are maxed out.

Very instructive, thanks !
So I assume if my fans never get maxxed out, my memory temps are 'considered' fine ?

Yeah, 3xxx series have because if not then memory would be toasted. It's sad nvidia went that path.

How can we know the mem temp ?

Like this, if you want to know how to do it then contact STSMiner for youtube link of that video, I forgot the link.

So ..... here's some info for you guys that have a new RTX 30x0 card .... this is mostly for the RTX 3080 / 90 cards.

The test below was not carried out by me, but I have managed to confirm the findings with my RTX 3090 I have.

The card used in this test -- MSI RTX 3090 Gaming.

Picture 1 -- Two heat sensors are placed on the memory chips that are on the back of the card.

Picture 2 -- This shows the card running in idle ..... nothing running, notice the temperature 33C

Picture 3 -- This shows the card mining Dagger / Ethash, the monitor on the left shows the card mining, the temperature on the memory chips climb to over 76C, this is what causes the cards to throttle down, the 3080 cards also suffer with this issue with the memory chips on the other side of the card (heat sink / fan side).
In order to get the most out of these cards, the memory chips and the VRM's need to be cooled down as much as possible.
Make sure you have plenty of air flow around the card(s) and give them space to breath.

This is my RTX3090 .....

You know mem temp is too high when fans start spinning like hell even when the temp of the core is low.. then hash drops too

3060 ti-s are great

Yeah it is for sure.
Fan spinning is regulated from core temp via afterburner, so how can they spin very high if core is low / normal ?

I have a fantastic 3060ti MSI TrioX wich gives 63.5mhs@PL 55%, 130W, core -502, mem + 1400 : fan 45%, core temp 48

I heard that GDDR6X from 3080 runs too hot when pushing memory OC high like I did for my little 3060ti
Is it the case ?

How can we know the mem temp ?

I have this one. 3 of them

solid 94-95 at 220 watts

Thank you again philip, I'm out of merits to give to you Cheesy

I'm waiting anxious to test this 3080, it's almost the same version you have, but mine doesn't have backplate (there's a difference of USD 100, so I prefer to stick with the cheapest)
I'll post on your thread after the tests
At least 94 Mhs is good for me, I just don't want that cards that are doing 88Mhs

I'll post results here once I've done some tests on it over the weekend.

Anyone here using EVGA XC3 Black? (that model without backplate)
https://br.evga.com/products/product.aspx?pn=08G-P5-3751-KR

I found one at good price, and I'm thinking to buy, just want to know if this card is good and can reach 100Mhs?
I don't want to buy and be on sub 90mhs

818 each after all coupons with 3 months to pay 0 %

they list on the evga website at 769 plus tax which for me would be 822.83 - 41 = 781.83 with 3 months to pay 0%

so the mark up was 36-37 a card. first two have been in hand for 11 days and earned about 185 x 0.03 x 11 = 61 dollars before power. I have a very temporary free power deal for these cards

so far 3 x 37 = 111 - 61 = 50 bucks over cost from evga direct. I get 3rd card on weds So by dec 7 or 8 the premium will be paid off.

I think I am getting them direct from evga in late December.

Not bad, the way things are, hard to get any 3080 below $800.

Yeah I was happy to get them at the price I paid.

All of my gpus will be fully paid off some time this december.

I have around 60 cards. Most are purchased after July 1 this year and under warranty. Free power ends in december. And i pocket 25% of the coin mined vs 100%. But gear is all paid off.

So the 25% is profit.

thehttps://www.evga.com/products/product.aspx?pn=10G-P5-3885-KR

EVGA GeForce RTX 3080 XC3 ULTRA GAMING, 10G-P5-3885-KR, 10GB GDDR6X, iCX3 Cooling, ARGB LED, Metal Backplate

P/N: 10G-P5-3885-KR

so far they work great

92-95 mhs each steady at about 240 watts 2 card rig runs 184-190 mhs

I have a lot of these 8 slot mobos

https://www.ebay.com/itm/Onda-B250-D8P-D4-Ver-1-00-12-GPU-Mining-Motherboard/143840755013?

I would love six rigs with 4 cards each

24 x 95 = 2.28 gh of hash

And how much have you paid for each one of them? So far EVGA and MSI seem okay for mining.

I've got an update regarding the Gigabyte Vision OC:

I managed to get a decent hashrate with it:

~96 Mh/s @ 224W
PL 61
core +90
mem +1000
Fan 75

core actually fluctuates between 1200 -1400Mhz
GPU temp (according to MSI afterburner) 51c in a closed case and @ 21c ambient temp
