Mining Ethereum with ASUS TUF Gaming GeForce RTX 3080 Video Card

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 absolutely laborious to seek out in the marketplace in the mean time and if you happen to handle to seek out inventory someplace the worth might be so excessive that you just in all probability would think about shopping for a RTX 3090 as an alternative. We managed to someway 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 we’ve got 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 mean time it’s what yow will discover and also you can’t be too picky. The TUF RTX 3080 works and performs very 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 answer that works surprisingly effectively with the three followers on high 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 is probably not that nice for players or PC fanatics it’s completely wonderful so far as Ethereum mining is anxious.

The cardboard comes with a 1440 MHz Base clock, 1710 MHz Increase 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 vast reminiscence bus. There are 8704 CUDA cores, 272 TMUs and 96 ROPs within the giant 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 effectively.

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%) acquired us at 87 MH/s Ethash mining hashrate. This can be 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 certain. With the cooling followers working at 100% even the 320W of energy utilization whereas mining is just not a lot of a problem with the common GPU temperature at round 52 levels Celsius. With a little bit of tweaking nonetheless we are able to optimize efficiency and scale back energy fairly effectively making the Nvidia GeForce RTX 3080 even higher for mining Ethereum for certain…

Decreasing the ability utilization from the default TDP degree of 320W to only 71% TDP acquired us to 230W of energy utilization for the RTX 3080 with even larger 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 larger overclock at +1100 for an additional megahash of efficiency, so that you would possibly wish to strive that as effectively, although we’re wonderful with the decrease clock because the cooling answer on this specific RTX 3080 kind ASUS is just not one of the 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 strong for a really very long time and you must in all probability undertake the identical philosophy as effectively.

Optimized RTX 3080 Mining Settings:
– TDP: 71%
– GPU: -300 MHz
– VRAM: +1000 MHz
– FANs: 100%

Since now we are able to measure the operating temperature of the GDDR6X memory chips with the HWiNFO device we’re going to be monitoring that in addition to you will need to maintain the video reminiscence on the lowest potential temperature attributable to these new quick chips getting fairly scorching underneath load. We’d not solely wish 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 in addition to have it working as cooler as potential. This is among the explanation why we use 100% for the cooling followers, though the GPU is just not getting that scorching at 52 C and might deal with decrease fan velocity with out growing its working temperature a lot.

One other attention-grabbing function that was extra lately launched within the HWiNFO device is the power to HotSpots on Nvidia GPUs, in order that in addition to the common 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 attributable to issues equivalent to unhealthy thermal grease or unhealthy cooler contact. Right here we see that the most popular spot of the RTX 3080 GPU is round 13-14 C hotter than the common working temperature reported for the GPU and that is type of regular, however then once more this can be 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. For example, on RTX 3090 we’re seeing working temperatures which are round 10 levels larger than those measured right here underneath comparable 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 twenty-four/7 operation. Nonetheless, if you happen to handle to get issues working at underneath 100 C for RTX 3080/RTX 3090 it ought to be wonderful, however you must attempt to scale back the temperature of the most popular reminiscence chip to round 90 at the least with a greater airflow as an illustration.

Getting 97-98 MH/s hashrate for mining Ethereum (ETH) utilizing the Ethash crypto algorithm is well achievable on Nvidia GeForce RTX 3080 GPU with round 230W of energy utilization. This ought to be potential on just about all reference designs (specs clever) 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 could require additional tweaking or completely different settings with the intention to obtain comparable efficiency on the identical energy utilization degree, although they need to nonetheless be capable of get you an identical hashrate if you happen to handle to maintain issues working cool.
