We’ve managed to get a Nvidia GeForce RTX 3080 GPU to mess around with mining Ethereum and different cyrpto cash, although right here we’re going to be specializing in ETH mining. The RTX 3080 is admittedly arduous to search out in the marketplace in the meanwhile and for those who handle to search out inventory someplace the value can be so excessive that you just most likely would take into account shopping for a RTX 3090 as a substitute. We managed to in some way get our palms on a single ASUS TUF Gaming GeForce RTX 3080 (ASUS TUF-RTX3080-10G-GAMING) video card to mess around with it for crypto mining and beneath you may learn what now we have discovered utilizing this GPU.
This TUF Gaming RTX 3080 from ASUS is certainly not the best mannequin yow will discover and undoubtedly not as spectacular as another playing cards, however nonetheless, in the meanwhile it’s what yow will discover and also you can’t be too picky. The TUF RTX 3080 works and performs rather well and the cooling manages to maintain the cardboard cool whereas mining even with inventory out of the field settings. The ASUS TUF Gaming GeForce RTX 3080 comes with twin 8-pin PCI-E energy connectors, 2.7-slot cooling resolution that works surprisingly nicely with the three followers on prime of the radiator. The default specs of the ASUS TUF Gamin RTX 3080 are those that the reference design Nvidia RTX 3080 makes use of and though that might not be that nice for avid gamers or PC fans it’s completely fantastic so far as Ethereum mining is worried.
The cardboard comes with a 1440 MHz Base clock, 1710 MHz Enhance Clock, 1188 MHz Reminiscence clock (19 Gbps efficient) and a 320W TDP. The RTX 3080 video card comes geared up with 10GB of GDDR6X video reminiscence that has a 320-bit extensive reminiscence bus. There are 8704 CUDA cores, 272 TMUs and 96 ROPs within the massive graphics processor that consists of over 28 million transistors. One hell of a graphics monster that’s solely bested by the even faster and better in terms of performance Nvidia GeForce RTX 3090, together with the crypto mining efficiency as nicely.
Utilizing the ASUS TUF Gaming GeForce RTX 3080 with its default out of the field settings for mining Ethereum (100% TDP, no clocks and followers at 100%) bought us at 87 MH/s Ethash mining hashrate. It is a nice end result when it comes to efficiency, although with default settings the GPU makes use of round 320W of energy and that may be reduces with some optimizations for positive. With the cooling followers working at 100% even the 320W of energy utilization whereas mining is just not a lot of a difficulty with the typical GPU temperature at round 52 levels Celsius. With a little bit of tweaking nevertheless we will optimize efficiency and cut back energy fairly nicely making the Nvidia GeForce RTX 3080 even higher for mining Ethereum for positive…
Decreasing the ability utilization from the default TDP degree of 320W to only 71% TDP bought us to 230W of energy utilization for the RTX 3080 with even increased hashrate. We’ve set the GPU clock at -300 MHz and the reminiscence at +1000 MHz in MSI Afterburner leading to 97.5 MH/s hashtrate mining Ethereum. The RTX 3080 can deal with a bit increased overclock at +1100 for an additional megahash of efficiency, so that you would possibly need to attempt that as nicely, although we’re fantastic with the decrease clock because the cooling resolution on this explicit RTX 3080 kind ASUS is just not the very best yow will discover on 3080 GPUs. And we like our GPUs not pushed to absolutely the most when mining, however at a bit extra conservative settings, however working rock stable for a really very long time and it is best to most likely undertake the identical philosophy as nicely.
Optimized RTX 3080 Mining Settings:
– TDP: 71%
– GPU: -300 MHz
– VRAM: +1000 MHz
– FANs: 100%
Since now we will measure the operating temperature of the GDDR6X memory chips with the HWiNFO software we’re going to be monitoring that in addition to you will need to preserve the video reminiscence on the lowest potential temperature on account of these new quick chips getting fairly sizzling underneath load. We’d not solely need to keep away from getting the reminiscence as much as a degree when it begins to throttle (round 110 levels Celsius) and begins dropping the hashrate, but additionally to have it working as cooler as potential. This is without doubt one of the the reason why we use 100% for the cooling followers, regardless that the GPU is just not getting that sizzling at 52 C and may deal with decrease fan pace with out rising its working temperature a lot.
One other fascinating function that was extra just lately launched within the HWiNFO software is the power to HotSpots on Nvidia GPUs, in order that apart from the typical working temperature that each one monitoring instruments report for the GPU now you can know what’s the hottest spot. That is particularly helpful for diagnosing potential points with GPUs which have been mining for some time and are displaying some instabilities on account of issues resembling unhealthy thermal grease or unhealthy cooler contact. Right here we see that the most well liked spot of the RTX 3080 GPU is round 13-14 C hotter than the typical working temperature reported for the GPU and that is sort of regular, however then once more it is a brand-new GPU.
The GPU Reminiscence Junction temperature that we’re measuring throughout Ethereum mining with overclocked VRAM with +1000 MHz in Afterburner is at 88 levels Celsius with the followers at 100%, with out the clock for the reminiscence it runs at round 82 C, so the additional clock doesn’t make issues a lot hotter. As an illustration, on RTX 3090 we’re seeing working temperatures which are round 10 levels increased than those measured right here underneath related situations. That is due the truth that the RTX 3090 had reminiscence chips on each side because of the bigger reminiscence config, so the RTX 3080 is doing higher, however the temperature remains to be fairly excessive in our opinion for 24/7 operation. Nonetheless, for those who handle to get issues working at underneath 100 C for RTX 3080/RTX 3090 it must be fantastic, however it is best to attempt to cut back the temperature of the most well liked reminiscence chip to round 90 no less than with a greater airflow for example.
Getting 97-98 MH/s hashrate for mining Ethereum (ETH) utilizing the Ethash crypto algorithm is definitely achievable on Nvidia GeForce RTX 3080 GPU with round 230W of energy utilization. This must be potential on just about all reference designs (specs smart) just like the ASUS TUF that follows the bottom specs set with the Nvidia Founders Version GPUs. Some fashions with additional elevated working clocks and voltages might require further tweaking or totally different settings so as to obtain related efficiency on the identical energy utilization degree, although they need to nonetheless have the ability to get you a similar hashrate for those who handle to maintain issues working cool.
