Hi guys,

I have the same problem here. Im using a Gigabyte RTX 3080 Gaming OC.

The only settings that I dont get a Thermal Throttling is: TDP - 52%; Mems: -500; Core -500; Fans - 90%, this give me 72 MH/s at 190W.

It took me days to find this thread and finally discover why my RTX 3080 dont generate the 100 MH/s.

Anyone has found a solution that doesnt involve voiding the warranty? Because I cannot disassambly the cooler without voiding the warranty (at least here in my country).

Also, I have a friend with a Asus RTX 3080 TUF OC with the same problem.



Never ever go cheap with cards and expect wonders... If you cant disassemble the crap coolers and lower the clocks is no option anymore, increase the fan speed further and/or use external 3000(+) high pressure fans in addition (like the Noctua Industrial). But this will hurt the lifespan of the original fans even more. So expect to replace them in the near future.

Go cheap? Its a bloody RTX 3080 card, even the entry level RTX 3080 is far cry from cheap, It SHOULD work properly. I dont really care about the lifespan of the fans, since this card has a 4 year warranty here.

I haven't watched all of hardware unboxed videos to see their reviews on this specific Gigabyte model but if you're dropping TDP down to 1/2 and lowering the clocks across the board you're basically only using 1/2 the card. I would just sell the card locally for a nice markup and find a different model of card or just buy the crypto directly. The Gigabyte doesn't have mixed caps so it was probably going to have issues right off the bat.

A friend got the Asus RTX 3080 TUF OC with the fancy MLCC caps and has the same problem. I dont think that is a cap issue, Gigabyte uses the 470u caps instead of the 220u caps (ZOTAC like), more than the double specified by nvidia.

It`s revolting that they have done something like that.

As Phil noted this is a case where mixed caps seems to filter multiple frequencies so that the heat buildup does get to extremes (see futher back in the thread for a chart he linked). Both the Asus and Gigabyte are thus bad models to use for mining because they're going with a single cap type. Obviously nVidia will remedy this with Rev 2 cards from AIB just like Asus had to RMA all those bad RX 5700 XTs that made poor thermal contact. Honestly, this is all nVidia's desire to say they were first to market even if it was a paper launch. Their Founders Editions had 6+ months to test out configs that worked and it looks like AIBs got screwed by having to rush to production.

Sometimes you get lucky buying the first batch because you might get better binned VRAM or higher binned chips (whereas lower yield chips would be saved for some cut-down refresh card). Sometimes you get screwed by meeting design defects and get to be the guinea pig. In this I couldn't even be a guinea pig because I could get my hands on one.

It still games well though as no game is going to run a constant 300w TDP through it. If you want the hashes, sell the card for a profit and just pick up a Founders edition. Phil sitting on 94MH/s sounds decent.

I have trouble getting my head around this explanation. The caps issue had to do with the cards being unstable when it boosted to high clocks - a remedy was to reduce the max clock speed.

Igorslab has done a test and showed high memory temps on the FE. The slowdown  in hashrates is very similar to my sapphire rx5700 when the memory temp reaches 104-106C.
It wouldn't surprise me if the AIB models that have this hashrate drop issue cheaped out on thermal pad quality.

Perhaps the reason why you are not seeing hashrate drops on higher end, mixed cap models is because they didn't cheap out on the memory cooling.


Well the original idea first brought out was  mixed caps allow for filtering more noise on more frequencies not my idea.  My thread had all the links.  others have done some teardowns and added high quality  thermal pads. with some decent results. later not first.

So  proper testing is get 3 shitty gpus  models with one cap style

get 3 good gpus models with mixed cap style

do teardown on all six pull all thermal pads on all six.

run all six at lowest power settings and low core setting and low ram setting.


then measure ram memory temps on all six.

if they all over heat equally then it is not mixed caps

After reading newer evidence from guys like you about pads and older evidence from the links in my thread

 I suspect caps and pads are the issue.  with a third possibility that the actual ram itself could be better quality in the evgas I use.

Time will tell and it will get teased out , but I am thinking the buying mixed capped evga 3080's seems like best solution short term.

I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

It might not be just cheapo thermal pads but can also be that the Gigabyte in particular is using flat backplate with no thermal pads between the backside of pcb and the memory gets hotter there on GDDR6/6X modules?

so far the only 3080's that have been reported as fairly good are the avgas and asus rog

both have proper cap mix so no crashing at high ram settings and maybe proper thermal pads.

So no over heating.  some screen shots pretty good numbers one card seems better then the other .

moboard is an old z170 with 4gb ram a usb stick and 4400t cpu.

What I am suggesting is I do have a 3080 TUF which isn't using mix caps but all MLCC and doesn't throttle so one example where it doesn't explain why throttling would be cause of one type of caps.
Memory cooling on other hand is unknown both because of pads and also because we don't have any reporting for GDDR6X temperatures.  Also the backplate is non vented for the gigabyte card.  The only other card that I am aware of using SP caps only is Zotac.

Having the same issue as others. ASUS TUF 3080 non-OC. Hashrate is varying, usually get between 95-75. Currently a bit more stable at 88-94 using 70 PL, -121 Core Clock, +1099 Memory Clock. Hoping this issue somehow gets resolved (if it isn't the caps) or i'll be returning before my 30 days is up.

I dont want to jinx your card, but mine started just like yours. Try it with +0 at memories and see if you get a stable MH/s rate.

Can you check the caps behind the core.  Is yours one with all MLCC caps?

seems stable.

2080 and 3080

0,725V 1320 Mhz Core to reduce the overall temperatur.

Waiting for my waterblock to reduce it further.
RAM + 1000 gives >97 MHs ETH, but lowers to 96 by time (and rising temp)

how hot is the memory running if you push it to +1000 mem? Seems kinda high.

Great question... that info they only have it some group people... For example Igorslab hat diese Sotfware to read it... He show a Pixe Photo of that information

Yeah my evga are solid so far.

I am getting a third one.  This is their 769 price model.

I played around with an added 120mm fan I will photo it later.

The fan seems to add more mhs I do more like 190mhs for the two vs 185mhs.

My back plates are vented.

Room temp is 30c or 84f

EDIT: Card stays stable at 94-97 MH when monitors are off and middle fan control is set even with left and right fans. Stays between 90-93 when monitors are on. Anyone reading this, set your middle fan speed in ASUS's software then use AB to set everything else.

So it looks like MSI AB is unable to control the GPU's middle fan, resulting in uneven fan speeds. Using ASUS's GPU Tweak II lets you set middle fan control. Using both software (ASUS to control the fans and AB to control the power limit, core clock, and mem temp) seems to let me stay in the 90's all the time (highs of 94 lows of 90). This is with the GPU powering 2 1440p ultrawide monitors. Gonna shut them off and report back on the MH in a bit.

I am headless running on this gear. via simplemining os.

but I just boosted fans from 71% to 81%

I was hashing 188 for 2 like 94 each.

lets see if the fan boost to 81% helps

hmm 192.12mhs I will post back.

I will get some photos today or tomorrow.
