RTX 3080 hashrate drop list

[rdluffy]

I've been playing with my MSI 3080Gaming X Trio for the days.
It can't do more than 86MH/s, no matter the temperature.
Issue is in the BIOS as when power reaches 205W it throttles.

I am using MSI Curve with minimum allowable voltage, 0.725 (in reality 0.731), and 1125MHz.
If I use normal PL level it does not do more than 82MH/s.
Also it must have a minus 120MHz on the memory, if I give it more it throttles instantly to 60-70MH/s.

Stay away from the Gaming X for minig!


PS. Yes, you loose warranty if: you change BIOS with any BIOS not destined for Gaming X (exception the 2 official ones= OC mode and silent mode - tested both, same 205W throttle limit), or if you remove the seal on the 4th GPU screw.

It's very strange, as I saw on some reviews, this card have TDP of 340w right?

I have an EVGA 3080 and I'm doing 98 stable, with 230w on software and 250w at the wall - I did fan curve to reach 1200Mhs on core clock with 718mv - 70% TDP
3080s are power hungry, and if I reduce even 1%, the card start to hash a lot less Mhs

I think your 1125Mhz on core clock is low, here I need exactly 1200mhz

But I don't know why your card only have 205w until throttle

Is it possible your card is having this throttle because of memory temperature?
Maybe after hit some temperature, the bios reduce the wattage to cool the board

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.

Thats odd i tested my friends xc3 ultra and it throttled after 1 min of doing 100 mhs.

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

Hi Guys, i have a Gigabyte 3080 Eagle OC with these thermal throttling issues. I'm aware that there is a fix for this, but warranty is voided if i disassemble the GPU, so, i was thinking on puting an aluminum heat sink with thermal pads on the Backplate, or some thermal pads and somewhat of a 80mm cooler. Has anyone tried any of this? Maybe there is some that i can do to lower the temps on the VRM/VRAM, i know that this gap between the PCB and backplate is the real issue. Again, RMA this GPU and getting another 3080 is near impossible in my country and i want to get some decent hashrates whenever i'm not playing videogames.

Zotac 3080 AMP Halo
I`ve got 3 of them - 1 is thortlteing - other 2 are not.
core -100, mem 1200, pl 220, fan 75 - gets 78Mhash for 180W - core temp 44
core -100, mem 1200, pl 190, fan 99 - gets 82Mhash for 190W - core temp 39
I had one, bought 2 more today :/ housed in same spot

What do you sugests ?
1. Run it under windows and undervolt hard
2. Sell it ASAP - not verry easy to get new one or replace.
3. i`m waiting for an manufacturer answer for my question - WTF ?! - In thorttle state, i cant change PL, even lower than 180 :/ ?!

EDIT:
THX to thiss community, hint with mem -200 helped but not solved problem. core -100, mem -200, pl 215, fan 99 - gives 86Mhash for 195 - core temp 41 - power jumps 195-205 and sommetimes it`s mining at speed of 87.

EDIT2:
It`s this model : ZT-A30800F-10P - ZOTAC 3080 AMP HOLO

 1º Zotac HOLO, getting 98.5 MH/s, no throttling.
+1100 memory, -300 GPU, 68 PL @ ~231W.

2º Zotac HOLO, getting 98.5 MH/s, throttling at higher clocks (not much, it drops 4mhs).
+1100 memory, -300 GPU, 68 PL @ ~231W.

Updating the thread:


MSI Suprim X: Have 2. One will cause a crash at more than +1000 memory, hashes around 92 only. The other one is perfect at 99-100mhs, 35-40C on 1200 memory -500 clock, 60% PW 60% Fan
Palit Gamerock: 6 of them in total, all run 98-101 at 200W, by far the best card for mining. +1200 mem, -500 clock, 60%, 60%

What OS, what miner ?
Need to check it on HiveOs

Edit:
Zotac support official statment: We do not support mining.

GPu works gr8 in gaming - checked that today.

Are both suprim x on the same bios ? I’m planning on making a 6 gpu rig with all suprim x . Don’t tell me they don’t all hit 99-100

I would like to share my result of using a "3080 GALAX OC" to mine ETH from Ethermine Asia server (phoenix miner)

I can do  101 Reported hashrate MS/s 240 KW on my PC

BUT!! There is a problem with Temperature

If the temp goes above 60 degree, hashrate will drop from 101 to around 80 MH/s

AND

I would like to ask about Current and Reported Hashrate

From my Dashboard sonetimes show:

Current: 85-100 MH/s

Report: 101 MH/s

How can i made the current hashrate to be more consistency?

Thanks

I don´t use Hive OS. I mine with Windows and Phoenix miner.

Share You`re command line.
I was using phoenix, but was slower than nbminer....but i`m getting 92 max.... it`s my gaming pc...normally im using hive for mining.

Zotac 3080 AMP HOLO started to throttle at 30c ambient.

If I keep it at 227w and core at 55c it is fine at 99mh/s. I don't think any of my 3080 can hold 35c+ ambients. Might be forced to limit to 210w and +800mem.

Hi i know this is old now but not finding much info.
I'm able to do +1300 on memory with 60% fan speed, but it has to be really cold, can get 100mhs.

Soo i'm trying to lower the mem temp power limit 66, memory +850, Fan 60 and it goes down to 86mhs.

Just wondering if a 2mm thermal pad would be ok? Thermal Grizzly Minus Pad 8.

Can i just do the back don't want to replace the front.

I'm just planning to do the igors pad mod.

My 3080’s are not thermal throttling but i did notice the backplate is super hot where the memory and vrams are located so i put a 120mm case fan on there .

Now its just warm to the touch not burning anymore .

Maybe try that and see if it fixes ur problem before u open ur card .

[lasttimei]

Yeah tried that atm i've a ryzen cpu heatsink at the top and it works somewhat, but i think ima try the thermal pad mod , just hope that the 2mm works fine.

[jelome198959]

Just noticed if I set the fans to auto on my Zotac, at 32c ambient fans went straight up to 100%. Definitely on the throttling side. I deshrouded it and zip tied 2x 140mm fans and according to HWINFO, fans are now at 75%. Went down from 100% to 75%. Big help. Let's see if this holds at 35c summer temps. Also checked the pads of the Zotac Amp Holo --- they are 2mm. Will replace the pads later if this still doesn't hold.

How does this work? I mean how did you mount the heatsink?

Can you please post pictures? Kinda interested how you did it
