just bought the zotac rtx 3090 trinity , but waiting for the power supply for the first run
how much mh/s would i expect with factory settings?

105 to 120 which depends on cooling of the ram on the backplate

I use simple mining os and get 111 mh/s

core -100
ram   800
watts 290
temp 70
fan.   80

in a minerdude case in a cool room

The cooler the GPU gets the higher your hashrate but the max I've seen is 120MH, I have a 3090 but I made sure that it's running on a single motherboard alone with no other GPU by its side, this helps when it's mining

i will do the same setup here

what power supply i can use with this card 850watt gold corsair or coolermaster

The TDP of 3090 Trinity is 350w, you will obviously reduce the power consumption to mine

850w is enough to run this beast with any kind of CPU + motherboard etc...

I prefer Corsair here in my country because I have 10 years warranty in some models, or 5 years in the mid end PSUs, and never had any problem with Corsair products
RM Series RM850 for example, have 10 years warranty and 6 PCI-E

I use a rm850 with and evga 3090 kingpin since april 2021 it should work well.

got 107mh/s at 58-63c core temp , but i cant read vram temp i am using nicehash os

mining on low settings getting 107.5mh/s at 60c core with nicehash os but how can i see vram temps i think the backplat is too hot when i touch

How about power consumption?
Did you lowered the power limit?

3080s and 3090s are hot, specially on the memory, you can put a 120mm fan blowing air into the backplate, it helps a lot to reduce the temperature
Some people even put heatsinks on backplate, but a fan should be enough



You can find a lot of content if you search on google "reducing memory temperature rtx 3090", some people make a new backplate, some changed thermal pads, you can read to understand better, about safe temps to mine, but again, a simple fan can help you reducing temp

does the card thermal throttle itself if mem temp reach dangerous levels

yes sometimes dropping ram settings does better as it runs cooler.

if you are running windows you can do gpu-z software to see your memory temp.

under 90 is better and at 100-110 it will throttle

no way for me to use windows again i am using nhos , but i will install windows and replicate the nicehash os low settings with afterburner to watch the vram temp if it is acceptable will switch to nhos with peace , but how can i know the low settings in nhos details so i can replicate

I never used Nicehash OS, but you can try Hive OS, it's simple to use and install
Hive OS shows memory temperature on Nvidia cards

But I agree with philipma1957, try windows to at least know your card better for a few hours or a couple of days, with GPUz you can extract a lot of information about power consumption, vram temperature, memory usage (here you can see if it's throttling or not) etc
You can use msi afterburner to make the overclock, and after that you can use another OS knowing which settings to use

Yeah especially with $2500 usd cards

The 3090 do 105 to 120 all depends on how cool the ram is.

finding the memory junction temp is good to do.

Since I don't do a lot of mods on these cards I simply lower ram a bit and watts a bit. Good fan action.

I keep getting decent temps and decent hash with ram backed off a bit and external fans.

on Simple mining os most cards can do 1000 to 1100 on ram clocks
and most card run too hot with that setting.

so more fans or drop ram to 950 or 900 or 850 or even 800

Most of my 3090 have ram at 950 smos settings.

one or 2 have 1000 ram setting

one or 2 have 800 ram setting.

most of my 3090 units including the Zotac do 106 to 117mh/s

thats what i though too , and i did install windows running NHQM and after some OCTune tweaks i got 100MH with 45c and 88c core and vram with 80% fan fixed speed Tdp 75% , i am still doing some memory tweaks to get 110MH without passing the 95c vram flag

also remember my 3090s are in minderdude cases which have five 140mm fans moving air bigly.

i have 9 of these cases the fans help cool the backplates and the ram.

i have 2 zotac 3090 trinity oc. use thermalright odyssey 3mm thermal pad for back vram. and add 2 delta fans

PL 90, mclock 1250

Nothing wrong with modding if it works and you are good at them.

Problem is you do them wrong and it voids warranty. but if you do it right most likely the best results are the 122 mh x 2 = 244 mh

I don’t do the full mods until warranty expires.

I have a good relationship with cards builders and my rmas are honored.

Nothing wrong with full mods on cards. But you need to be good at them.

most all these cards have bad pads and just use backplate as a heat sink.

I have seen multiple mods on many youtube videos and went the way of minerdude cases and no mods

run at 275-285 watts with clocks at 800 to 1000 for ram.

I have a dozen of different 3090s  and they run at 107 to 117.

if they all were modded to 122 I gain about 100 mh and worry about warranty.

314 watts is too much, my 3080 uses 220 watts and does 103 mhs, maybe if you decrease power to lower hashrate, it will use a lot less power. I wonder if at same power of my 3080, i mean at 220 watts, maybe that 3090 can do better? i wonder, maybe 24gb of ram uses a lot of electricity, my 3080 is only 10gb. Anyway, 103mhs after thermal pad replacement, memory temp junction stays around 76c, there is that too.

96% fan is too loud in zotac , i can get better hashrate and temps with this fan settings but i put the noise in my calculations

i got 110Mh but with 90c vram temp is that ok for 24/7 mining

How do you people even deal with 3090s? My reference 5700xt flares up at the memories. Changing thermal pads didn't help(used 2.0mm ones). I'm thinking of buying an aftermarket cooler but they are sold out everywhere. Can't imagine myself having a 320w monster

maybe

 I do 87-88 5 months so far. So in theory  you could be good. Or not.

I would shoot for under 90c

 But 90c is under the 95c throttle point.


My 3090 are good in the minerdude cases due to powerful 140mm fans in it.

https://minerdude.com/product/x12012022/

All my 3090's are okay so far in these cases.

Frankly I do not rush to get 3090 cards

I alternate the in the 12 card cases six or 7 cards max.

I run them at 275-290 watts

But they are not ideal cards.

I could get them right now at newegg

https://www.newegg.com/msi-geforce-rtx-3090-rtx-3090-gaming-x-trio-24g/p/N82E16814137595?

put 6 in a minerdude case and I don't

price is too high at 3000 a card

still fighting for lower vram temp , but also don't want to lose 10MH for it maybe i will install two 120mm fans on the backplate and see what will happen

i run it in an open case setup , if i used a gaming case with strong air flow can i get lower vram temps
