Even with thermal pads it hits 108 ? Did u bother getting good quality thermal pads or just got random stuff ?

MSI 3080 Suprim X Thermal Throttling here, unfortunately!

Started ok, after two weeks it started slowly decreasing the hashrate.

On HIVEOS

Before:
FAN SPEED - 95% ( doesn't go higher)
Clocks: -500, 2725 memory, 250 PL
Core temp: 42°c - 99.9 mh/s.

Now:
42° c - 96.5 mh/s!
Same settings.
 

Any advice?

Advice. Core 0, Memories to 1750 (hiveos). Power limit 220W. 94/96mh.  For 5 or 6 mh more ... it is not worth stressing the memories.

Palit GamingPro RTX 3080

All stock nothing changed, working steady almost two months with hashrate keeping at 100 MH/s range mining ETH

Temps
 - GPU temp does not go over 48°C
 - GPU memory junction temp varies between 75-82°C max (keeping in mind surrounding temp was around 20-25°C)

Clocks
Core: 0 / Memory: +1250 / Power: 75%

Mining:
Hashrate: 101+ MH/s
T-rex, nicehash, phoenix... various pools

I must say im very happy with performance and cooling of my palit card, pleasantly surprised

Thermal throttling or bios coating.

It would help, when all posters tell their VRAM temperature and tell
if they have extra fans blowing on the card.

[th00ber]

3080 and 3090 need fresh air on the backplate.
Add some fan to blow the backplate, it is simple and will really help

I do this on my 3090. If not it throttle to 90 Mh/s after some minutes, but with backplate cooler, I run at steady 112 MH/s for 295W

you are killing a good piece of gear.

you overclocked the ram bigly
you set the power too high
and you run the fans too high.

the chances are pretty good you permanently hurt your ram.

set the fans to 80%
set the core to -300
set the ram to 1400
set the power to 230

and hope you did not hurt your ram permanently.

Even when doing that the memory still runs at +95C on the 3080’s .

I had the room at 18C , cards running at 35C and memory was still reaching 90-95 depending on the card . I have a fan blowing on the backplate for all the cards

EVGA XC3 ULTRA GAMING, getting 102 MH/s when not using the monitor, no throttling.
Fans at 60%, +1500 memory, -200 GPU, 70 PL @ ~240W.

Had a Gigabyte Gaming OC before; was thermal throttling with PL 60, was pulling between 85-91 MH/s. Glad to be rid of it.

I tall depends on the backplate and location of thermal pads, if they are good the memory will not throttle!

I can get with lolMiner 100Mhs with less that 240W in my Gigabyte ... But I made the Thermal Pads not only in back plate also I replace the original and I take out the large connector to give some extra ventilation... and it works greats...

Now I have at 96Mhs at 217W... I prefer to save that 20W for 4 Mhs...

So gigabyte gaming of is fixable by thermal pad replacement?
Did you use 3mm or 2mm? I can't find 3mm anywhere

Thanks

I did only find the 2mm (Thermalright Thermal Pad 12.8 W/mK, 85x45x2mm).
I got good results, 20 degress celsius less on Memory Junction.
Core and GPU hotspot increased 6 degrees each, maybe more heat from memories on copper, or bad thermal paste reapply.

I forgot to try the remaining piece of thermal pad on backplate, not sure if 2mm would fit in the gap (and not fall).
I think if with precise cutting you can use a single thermal pad sheet on both front and backplate (if 2mm fits backplate).

But be warned, you'll lose your warranty and Gigabyte Gaming OC fan connectors are a hell of a job to remove them, almost broke 2 of the 3, I almost gave up...
I'm certain that if for any reason I rma this card, it'll be rejected.

For curiosity, my Gigabyte had much less grease/oil from original pads than what I saw in some videos...

I know it can give 100 mh. But for 5mh I'm not interested in stressing the memories It is a very expensive chart to play.

I got my EKWB Blocks for the Supreme X yesterday.
Just want to inform all that the pads might be too thin.
1. GPU Asus TUF 62 degrees (watercooled)
2. GPU MSI Supreme X 96 degrees (watercooled) and still slowly rising.

Just did a second try and it didnt change the temp.
But i recognized nearly no imprint of the rams in the pads.
I should have 1.5mm here for a 3. try.
EKWB sends only 1mm pads.

So after mounting of the block, check the ram temp with hwinfo....

Edit:

Changing the lonely ram pad at the 16x PCI-E from 1mm to 1.5mm dropped the ram temp by 30 degrees.
Sounds unbelievable but is true...

Edit:

RAM +1149 = 99 MH/s
RAM +1200 = 99.4 MH/s
RAM +1300 > 100 MH/s

Core 1275 MHz ( too lazy to drop it  more)

Would be interesting to know if keeping it air cooled while changing the pad at the pcie16 spot would cool it the same . I’m assuming i’d have to remove the backplate which would void my warranty ?

[Wotan Wipeout]

You have to remove the heatsink, not only the backplate.

Looks like the next supreme x has got the same problem with the ekwb cooler.
All 1mm pads used - temp much higher than expected. Hope its the same spot.

[Wotan Wipeout]

3080 eth max hashrate with exchange of the bespoken ram pad.

CPU is a 5800x, so the monitor is attached to the first gpu, lowering the hash a bit.
Highest ram temp after 2h 80 degrees.
