The MSI GeForce RTX 3090 SUPRIM X 24G (Nvidia RTX 3090 or GA102 graphics processor) options 10496 CUDA cores with 1860 MHz Increase clock for the GPU, it has 328 TMUs and 112 ROPs, the SM depend is 82, there are 328 Tensor cores and 82 RT cores. The cardboard is supplied with 24GB GDDR6X video reminiscence with 384-bit broad reminiscence bus working at 1219 MHz with 19.5 Gbps efficient reminiscence pace for a whooping bandwidth of 936.2 GB/s. Usually the RTX 3090 GPUs are rated at 350W TDP and wish 2x 8-Pin PCI-E energy connectors, however these SUPRIM X playing cards have a TDP of 420W and have 3x 8-pin PCI-E energy connectors. That is necessary because it means that you’d want 18x 8-pin PCI-E energy connectors and a strong sufficient energy provide or truly two for that matter to make your life simpler. The cooler of the video playing cards is huge and really efficient, there’s a backplate with heatpipes on the again and triple followers with twin ball-bearings to maintain issues cool and never very noisy even when working at 100% speeds. Conserving every part working at low temperatures is essential when mining and particularly with highly effective GPUs that use a variety of energy. The GeForce RTX 3090 SUPRIM X 24G is definitely cooled so far as the GPU is worried because the working temperatures at inventory settings are fairly low, however the concern that must be addressed with RTX 3090 can also be conserving the GDDR6X reminiscence chips as cool as attainable. The video reminiscence will get scorching, particularly when utilizing the cardboard to mine Ethereum (ETH) and you’ll expertise hashrate drops in the event that they get too scorching, to not point out that they can provide you additional hassle if not correctly cooled whereas mining within the not-so-distant future.

Why use Nvidia GeForce RTX 3090 video playing cards for mining when they’re much costlier than Nvidia RTX 30 sequence GPUs and once we know that they aren’t going to supply us one of the best value/efficiency match for Ethereum (ETH) crypto mining. For the time being with all of the GPU shortages on the markets it’s you mine with what you will get and whether it is RTX 3090 then it’s RTX 3090. After all, there are alternatives that supply higher value/efficiency ratio resembling RTX 3080, RTX 3070 and even the RTX 3060 Ti, however the RTX 3080 is definetly the only option you have got, however then once more additionally it is the toughest if not not possible to search out in the meanwhile. The runner up is the RTX 3060 Ti as it’s the most cost-effective 30-series GPU to provide you actually excessive hashrate for Ethereum mining, however one other one which can also be very arduous to search out. So, plainly the RTX 3090 are simpler to search out due to their very excessive value with RTX 3070 playing cards additionally extra simply popping up once in a while, not like the RTX 3080 or RTX 3060 Ti. The Nvidia GeForce RTX 3090 is certainly the quickest video card for Ethereum mining in the meanwhile with its inventory hashrate of roughly 105 MHS at default settings, however you possibly can tweak it a bit to rise up to round 120 MHS. In case you handle to get your fingers on RTX 3080 GPUs then don’t hesitate as these are considerably cheaper and might nonetheless offer you about 90-95 MHS hashrate with tweaked settings.

As already talked about, the MSI GeForce RTX 3090 SUPRIM X 24G GPU is able to supplying you with round 105 MHS hashrate for Ethereum mining out of the field at inventory settings and meaning about 400W of energy utilization per GPU. With a little bit of tweaking you will get higher hashrate and with a decrease energy utilization – decrease electrical energy bills and higher cooling for long run mining operation with out issues. On the RTX 3090 it’s a clever concept to go for 100% pace of the cooling followers, so be sure to get GPUs with good high quality ball-bearing followers (sure, there are RTX 3090 GPUs with sleave bearings being offered by some manufacturers!!!). We begin by reducing the Energy Restrict degree down till we see the hashrate beginning to drop under the MHS we get at inventory settings, within the case of the MSI RTX 3090 GPUs this occurred at round 65% TDP. So, with 35% much less energy used we will nonetheless get 105 MHS mining Ethereum (ETH) with RTX 3090, that means there isn’t any cause by any means to waste any further energy with none extra efficiency. Then it’s time to overclock the video reminiscence and in some unspecified time in the future, we may additionally have to bump up the TDP degree with a couple of p.c to permit extra headroom as a result of elevated reminiscence energy consumption for the additional hashrate. The settings under for the MSI RTX 3090 SUPRIM X GPUs present us with a hashrate of 120.9 MHS per GPU mining Ethereum or for the entire 6x GPU mining rig we get a bit over 720 MHS complete and that’s a powerful quantity for a single mining rig with simply six video playing cards in it.

Optimized RTX 3090 Mining Settings:
– TDP: 73%
– GPU: +100 MHz
– VRAM: +1100 MHz
– FANs: 100%

With these settings PhoenixMiner studies a bit over 1800W of complete energy utilization for the six GPUs with a bit over 300W per GPU, however measuring the facility consumption on the wall and bearing in mind the opposite elements within the mining rig in addition to the facility provide effectivity the overall energy utilization for the entire rig is extra like 2100 Watts, the vitality you find yourself paying for. Because of this a single 2000W PSU resembling Leadex Tremendous Flower 2000W will not be sufficient (we all know, we examined it) with the next settings. In case you drop down the Energy Restrict to about 65% you possibly can handle with a single actually good 2000W PSU, however will probably be pushed close to its restrict, so not a good suggestion on the long run for a lot of causes. To not point out the truth that a single even 2000W PSU doesn’t include sufficient 8-pin PCI-E energy connectors and utilizing cable splitters on such power-hungry GPUs is rarely a good suggestion because it might trigger points with the facility cables or PSU connectors burning. What you should simply do is add a second much less highly effective PSU, so we ended up doing 4 GPUs on the 2000W Leadex after which added a second Corsair 1200W PSU for the remaining two playing cards. This fashion the mining rig can work properly even at 100% TDP with full load with out having hassle with the facility provides, simply know to be on the protected aspect that even 2x 1200W energy provides is perhaps on the sting, so contemplate going with a bit extra highly effective PSUs to be on the protected aspect.

Primarily based on our expertise thus far, the +1100 MHz reminiscence overclock appears to be the candy spot for the RTX 3090 and in addition on the whole for different Nvidia GeForce RTX 30 sequence GPUs when it comes to efficiency, stability and working temperatures when utilizing the playing cards to mine Ethereum. Positive, it’s attainable to get a bit larger working frequency as much as about +1300 MHz on some GPUs, however not all may fit secure and albeit we’re extra involved in regards to the working temperatures of the GDDR6X chips when overclocking an excessive amount of. Increased working frequency means larger temperature and extra energy used, to not point out that the additional increase of about 1-2 MHS you get by pushing the video reminiscence additional is probably not well worth the hassle. So, single MSI GeForce RTX 3090 SUPRIM X 24G video card doing 120 MHS at a bit greater than 300W of energy used for mining Ehtereum (ETH) and a 6x GPU rug with Nvidia GeForce RTX 3090 playing cards doing 720 MHS in complete is certainly spectacular efficiency. The GeForce RTX 3090 GPUs are a bit graphical efficiency monsters and that goes not just for reminiscence intensive crypto algorithms like Ethash, however for extra GPU intensive ones as properly. That might in fact want some extra time testing and experimenting with and may have totally different GPU/VRAM/TDP settings for the playing cards as a way to maximize efficiency in a selected algorithm…
