RTX 3080 hashrate drop list

Phoenix miner inflates hashrate by about 3%.

So 3080’s don’t actually do 100mhs ?

If pheonix miners inflated the hashrate wouldnt it be reported 3% lower on the pool side ?

3080s can still do 100mh/s+ without using Phoenix, it's a bit of a silicon lottery.

I use Trex miner. 5 x 3080s. 2 do 102.8mh/s, 1 x 100.9mh/s, 1 x 98.8mh/s, 1 x 96mh/s

In fact, I had to stop using Phoenix miner for my 3080 rig as I got way too many stale shares.

All these figures are a bit pointless without mentioning power level/draw etc. I'm sure even my Shitabyte Gaming OC can do these figures if I increase power.

Hopefully this suits your needs.  Included the memory temps for the Shitabyte Gaming OC cards The "hot" one is the MSI Suprim.

Can you share your settings? 73/76c junction temp is really impressive. environment temp?
Gigabyte version?

Ambient temp is 22c. All the Gigabyte cards are modified with new thermal pads front and rear(between the PCB and backplate).

Three of the Gigabyte cards are Gaming OC, One is a Vision. No power limit set, all have vcore locked at 725mv and using the stock core frequency "curve" for the card. I.E. there is no core frequency offset. They all vary on core clock due to silicon lottery.

The Gaming OC cards, 1 does +1175mhz memory offset(One of the 222w cards in the image), 1 does +800(226w, this card lost silicon lottery, it's really inefficient compared to the other cards I have), the last does +550 on the memory, 209w card, seems it has a power efficient core but the memory sucks. The Vision card also does +1175(222w card)

The Suprim is the most energy efficient card. I haven't modified it like the Gigabyte cards, so the memory temps are much higher and therefore I think what is holding back my memory overclock of +1000mhz.

I have 4 suprim X and one trio X on suprim fw.

Today one of the suprim X hit 110 junction temp and is now throttled at 94-96 mh. The others are all running at 99 with junction temps between 98 and 104 .

I’m surprised my trio X did not hit throttle before one suprim X .

Is my only option now to remove the backplate and change the thermal pads ?

Would msi know i opened the back plate ?

Anyone got info for the Aorus Master 3080?

Does it thermal throtteling or is it good?

[1337leet]

I got the Gigabyte AORUS GeForce RTX 3080 Master and it's working like a beast 97.5 MH 24/7 240w

Still 97?
Memory temperatures okay?

Brand used? 2mm, 3mm or a mix?

I bought a sheet of this and cut it up accordingly. https://uk.rs-online.com/web/p/thermal-pads/1745712/

To stop thermal throttling you would need to change pads, yes... MSI would find out when they take it apart unless you put back all the original pads. Then you might get away with it.

Could someone comment if the EVGA GeForce RTX 3080 "XC3 BLACK" GAMING 10GB  has thermal throttling?

[Miningminds]

Would like to share my results with the community, I have 2 msi 3080 ventus 3x running for 3 months now.

The first one settings:
69 power limit
-150 core
+625 memory
80 fan speed

and it does aprox: 93,7 mh/s with a 220w consumption

The second one:
69 power limit
-150 core
+734 memory
80 fan speed

and it does aprox: 94,8 mh/s with a 220w consumption

I would like to comment that both heats up to 110 degrees junction temp with 26º environment, and some times even going up to 112 so decided to modify the first one with newer thermal pads and also thermal paste. However I have to tell that the cards even running all time at 110º it never suffered from throotling.

The final results are quite impressive for me, as the tjunction memory reduced from 110 degrees in average to 90 constantly.


If someone is interested in improving the temps in this card model, I bought these pads: Thermal Grizzly Thermopad Minus Pad 8 (2 mm) and One enjoy Thermalright Thermal Pad 12.8 W/MK, 85x45x1.5mm


Nevertheless, I tried with the modified card to overlock a bit more until +800 memory and after some minutes, the card hangs out and stop running, so I suppose that silicon lottery bad for me and I can't recommend this model for anyone.

My cards have been mining fine for almost 50 days non stop, 3080s are the way

card #3 crazy efficiency, almost like my best 3060 ti

I might just try that and put back the thermal pads how they where if ever i need to RMA. U sure theres no other way they can tell i removed the backplate ?

Sucks cause i bought these cards that retail more than other brands because i didnt wanna have to deal with heating issues . Had i know i would of saved some money and get the evga xc3 ultra .

170w! That's insane. I'm wondering if it's a misreading it's so good.

The xc3 also get hot and do thermal throttling if an oc is done.

Some of my cards have a guarantee seal on the screws which you need to break to unscrew the backplate.

I've more than one
3080 Gigabyte Gaming OC
PL 220, but they use only about 190W
-200
+1900
42-45C
67-75MH
Hive OS Linux
455.45.01
Ethminer

Others are working at 220W as predefined at ~87MH. Any Ideas?

Any of you guys have a 8-10% difference between effective current hashrate and current hashrate ?

I’m using pheonixminer on ethermine .

I’m using pheonixminer on ethermine .

Yes, I had a lot of stale shares with pheonixminer. So I switched to Trex and the problem disappeared. I'm using Nanopool.

But its odd cause my 1070 rig reports the same on all counts . The 3080’s are the ones with issues

[Ruso21]

Gigabyte Aorus Xtreme - 99.5 mh no throttling with 80% fan

can you share the settings?

Power Limit:

Memory Clock:
Driver version:
Windows or linux?
Which miner?
Did you put thermal pad?
