Are the Nvidia 3000 Series the BEST GPUs for MINING EVER?! RTX 3070, 3080, 3090

[heavyarms1912]

My Gigabyte 3080 drops hashing after mining for a minute or two.

Tried changing risers and power connectors to no avail.

I have Silverstone Platinum PSU 1200 W.

The hashrate drops on both everything stock and TDP at 80 or 70 or any other value as well.

I have the same issue as you, with an RTX 3080 Gigabyte Eagle OC. Starts out at 88Mh, slowly dropping to 77Mh.
I installed the GPU straight on the motherboard. I noticed that the reason for this is that the core clock is dropping automatically to around 1000Mhz for some reason.
Also, total power consumption according to Phoenix miner is around 200W. (same thing with Claymore btw)

Did you find a solution for this problem? Thanks

it's thermal throttling the GPU on memory intensive algos.  Try opening gpu-z and running ethash.  when the core frequency drops it would show perfcap as 'Thrm'.
Something is getting quite hot on that GPU either the VRM or GDDR6X modules.

okay there is no solution. the caps are a poor design and they cause memory to overheat.

what can you do?

downclock

and jack the fan.

set fan to 85%
set tdp to 65
set ram freq just under stock
set core to 900

you will get about 80mh but power use should be a lot lower. 175 watts

if you can manage to blow air with a fan on the caps in question do so.

come back and let us know what these settings do.


once cards are in stock say jan or feb turn it back for a rma as the new ones should have better caps.

Not worth the hassle, what is the point of buying a gpu that you can't use it fully? terrible job, no good cooling, gpu won't last long, so forget, reason you people need to wait reviews and see how thermal tests fare.

which caps are you talking about?  Why would the caps only get hot while mining memory intensive workloads?
The card doesn't throttle on benchmarks even while hitting core temps of 70+

[geck]

If you look at gamers nexus tear down of the gigabyte eagle oc model, there are a couple of memory thermal pads that are not making full contact. The pads also lookreally thick.

Have you considered/tried removing the cooler and replacing the pads?

memory frequency the higher it is the more it stresses the cap designed to filter noise etc. noise make heat.

so yeah better thermal pads help somewhat but multiple cap designs tweaks to multiple frequency points will help.  since setting ram to a lower frequency does not ruin warranty do it. and the gear will be better.

Yeah I knew about these cap issue but internet mentioned they weren't as bad as originally thought they would be.
Anyways I've ordered some thermal pads will see.  My plan was put some near the memory chips are between the backplate and pcb.  Can check if the caps could be given some thermal padding too.

Usually first time buyers are guinea pigs anyway. No wonder why there are too many issues.

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.

[fmz89]

in year 2015 r9 390 is 8gb. 3070 is 8gb in 4th quarter of 2020. even gamers will despise that card LOL

3070 is equal to 2080ti performance? 2080ti is still almost equal to 1080ti performance, 1080ti is circa 2017

3070 is garbage.



if 3080 vs 3090 for mining...

..is like 280x vs 290/390, then 3090 is waste of money and power (vrams that are not utilized consumes power, cost more than 2x of 3080)

..is like 1080 vs 1080ti, then maybe 3090 is a good card.

good point 3090 is waste even for gamer, maybe for video editing 8k usefull, no choice here

tahiti card is the first amd compute card, and beastly on double precision performance 1/4 ratio from single precision

 is the first gpu widely consume by miner and scientic

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.

[philipma1957]

my evga arrived today. mixed caps.

dead solid at 94.5mh

230 watts no issues.

the asus tuf has one cap not mixed.


what a cap does you would realize the problem is

470u vs 220u

means the 470u filters lower frequency better.

and the 220u filters higher frequency better.

so if you have one or the other you miss a section of frequency noise which cause more heat.

If you have both sizes like the evga has it works on both sets of frequencies which means less heat on the ram.

every model with all caps the same sucks

and models like evga with both caps work better.

Since soldering new caps is next to impossible for most people putting in really good thermal pads will help
somewhat.

But don’t  buy a 3080 unless it has mixed caps.

Unfortunately I would like to add a data point to this.  I also tried with a TUF 3080 which has all MLCC caps.
https://imgur.com/a/UErgjR2

It throttled when the fan were turned down below 50% and temperatures were allowed to rise then I switched it to auto again and saw the core frequency rise back and Thrm perfcap move to Idle.

This feels like the GDDR6X modules getting way hotter and throttling the GPU core rather than a cap issue.  It might not be able to drop to lower power state though in which I would expect the GDDR6X clocks to drop as well.
The gigabyte card too was able to maintain hashrate to larger extent once the fans were set to 100%.

@joseph32 the TUF is $699 MSRP and implemented a separate heatsink for memory modules.  Gigabyte Gaming OC card is $749 MSRP.  Go figure.

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.

[arielbit]

In mining you need "temperature space" where the area is cool enough to run those 3080's, increasing fan speed of those cards are temporary fix or a minor fix.

Just like you need to have "electrical space" where you can pull enough amps from your circuit for mining to be worth your time.

Just like you need "dirt space" where you don't have to clean your cards.. like every week hehe

Just like "noise space" where you can still function as a normal human away from mining.

Just like "plain space" where you have enough room for those cards.

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.
