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 Wink

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 ?

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.
