RVN is likely one of the hottest cash for mining, preceded solely by Ethereum (ETH) and Ethereum Basic (ETC) by the variety of miners. The cryptocurrency belongs to the Proof-of-Work consensus algorithm and makes use of a hybrid algorithm (Kawpow) that engages each GPU core and GPU reminiscence.

We suggest mining RVN within the 2Miners pool. As of now, greater than 22 thousand customers mine this coin within the pool.

Ravencoin makes use of KAWPOW mining algorithm which is taken into account sizzling. It closely relies on GPU overclocking and energy restrict (PL).

Is GPU Overclocking for Ravencoin and Firo Mining Totally different?

On October 26, 2021, Firo carried out a tough fork that resulted in switching from MTP to the brand new algorithm known as FiroPoW.

We wrote about it within the devoted article titled “Firo (ZCoin) Arduous Fork. New Algorithm – FiroPoW. Learn how to Put together?”

FiroPoW is a modified model of ProgPoW. The identical goes for KawPoW used for RVN mining.

Because of this, these two algorithms, FiroPoW and KawPoW, are each ProgPoW’s modifications. They’re so comparable that the overclocking rules are the identical for each. Despite the fact that this text is about RVN mining, you’ll be able to simply use it to overclock GPUs for FiroPoW to mine Firo.

Learn how to Overclock GPUs for Ravencoin Mining

If you wish to overclock your video playing cards, you have to be able to experiment. One of many elements to contemplate is the price of electrical energy. Other than the typical optimum overclocking parameters, we will apply onerous undervolting that ends in solely 80% of a mean hash fee however decreases GPU energy consumption by 33–39%. And we will virtually all the time do the opposite: acquire 10–15% of hash fee however enhance energy consumption by 22–30%.

It’s vital to notice that profitability calculators all the time point out sure common optimum overclocking parameters for every mannequin relevant to most GPUs. Nevertheless, skilled miners ought to know the minimal and most capability for every of their GPUs.

For instance, the RTX 2070S can provide out 17.05 MH/s consuming 89 W (5.22 W per MH/s), however it may well additionally give out 20.88 MH/s consuming 121 W (5.8 W per MH/s). And in case your electrical energy is tremendous low-cost, you’ll be able to even overclock this graphics card to 26.05 MH/s consuming 209 W (8 W per MH/s). On this case, an excellent GPU cooling setup is a should.

Within the desk under you’ll be able to see a number of the most fascinating overclocking eventualities and RVN mining hash charges on totally different NVIDIA graphics playing cards.

We used T-rex 0.24.2 to get the info. We’re going to replace the desk once we check new GPUs or when higher performing mining software program comes out.

GPU Overclocking for Kawpow Algorithm

When mining this algorithm, principally all GPU overclocking parameters have an effect on GPU hash fee. So it’s best to overclock the whole lot. But when you’ll overclock abruptly, you gained’t know the place the issue is in case your GPU turns into unstable.

So it’s best to overclock regularly.

Step 0. Earlier than overclocking, calculate the algorithm profitability utilizing 2CryptoCalc. Then write down how a lot you pay for 1 kWh of electrical energy.

Because of this, it is possible for you to to estimate overclocking effectivity permitting for electrical energy price. Now you should utilize these values to resolve what GPU energy consumption degree is cheap for you.

Step 1. Discover the max steady reminiscence clock.

Transfer the reminiscence clock up at +50 MHz intervals till you attain the max stability. Transfer one step down.

Vital: When GPUs get sizzling, GPU reminiscence chips get sizzling as nicely which brings overclocking stability ranges down.

One other vital factor to recollect is that you just don’t have to activate the tablet for the 1080 and 1080ti. At a set PL fee it gained’t offer you further hash fee, however it would destabilize overclocking.

Step 2. Core overclocking.

When you mine utilizing Home windows, set the core voltage in MSI Afterburner. It can make overclocking extra steady and enhance the max vitality effectivity.

Transfer the core clock up at +25 MHz intervals, discover the max steady worth, transfer one step down.

In case you have a multi-rate electrical energy meter and also you need to routinely change to the chilly mode at the next electrical energy fee and overclock GPUs at a decrease electrical energy fee, it’s best to overclock the core in all set factors.

It’s best to begin with the very best voltage level. Keep in mind that the upper the core voltage the much less you’ll be able to overclock. The max overclocking of the identical graphics card at 950 mV is +125 MHz, at 800 mV – +175 MHz, at 700 mV – even +225 MHz, particularly for the RTX 30xx sequence.

On this case it’s best to depart a margin for the upper voltage factors transferring 50 MHz down. It is a vary the place GPUs turn into most unstable, and if the driving force crashes, all set factors get erased.

RVN & Ethereum Twin Mining

Fashionable GPU reminiscence can simply retailer the info wanted to mine two cryptocurrencies on the identical time. Nevertheless, they’d compete in opposition to one another for reminiscence and core, so the ensuing hash fee would principally rely upon the depth of every algorithm.

Observe that Home windows 10 consumes extreme GPU reminiscence quantities on all GPUs. Twin mining is unimaginable on GPUs with solely 8GB of RAM, however it’s attainable if you happen to use Home windows 7 or Linux-based OS for mining like RaveOS.

In actuality, contemplating that Ethereum is essentially the most worthwhile cryptocurrency for mining on the earth, twin mining in 2020–2021 has turned out to be inefficient on GPUs with out LHR lock.

For instance, the RTX 2070 Tremendous can mine only one algorithm and provides out 40+ MH/s consuming 93 W within the case of Ethereum. If GPUs can maintain a reminiscence clock at 7800, they can provide out even 42–43 MH/s. When mining Ravencoin, you will get 21 MH/s at a decrease consumption fee of 121 W and 26 MH/s at the next consumption fee of 200 W.

When you dual-mine algorithms with totally different depth, you will get 16.5 MH/s for ETH and 16.5 MH/s for Ravencoin consuming 200 W of energy. It’s virtually 40% for Ethereum and virtually 70% for RVN.

It’s simple to note that within the final two years you virtually all the time get extra revenue if you happen to mine only one coin – Ethereum. It additionally consumes a lot much less energy.

Observe that we used totally different mining applications for testing in order that we might alter the depth of every coin. The ensuing values won’t be the very best attainable.

In case you have LHR graphics playing cards, in principle you’ll be able to strive twin mining, though you gained’t see a major enhance in revenue. This feature solely is sensible in case your electrical energy charges are low.

RVN Mining on Nvidia RTX 30хх

As you’ll be able to see, RVN mining hash fee is normally half of that of ETH in megahashes.

The RTX 30хх sequence, in addition to the 20хх, function extraordinarily quick reminiscence that may transmit massive quantities of information and makes use of extraordinarily excessive clocks. On this case knowledge bus turns into a bottleneck.

That’s why GPUs with equivalent knowledge buses have comparable mining hash charges. Some examples are: the 3060ti and 3070, or the 2060S, 2070, and 2070S.

After the 30xx launch GPU cores grew to become extra highly effective and the reminiscence grew to become even quicker, however the knowledge bus dimension remained the identical. So it’s doesn’t make a lot sense to overclock the core: RVN mining hash fee on the 3070 can’t go above 30–33 MH/s. However, energy consumption will go up. So to attain the utmost vitality effectivity on the RTX 3070 or RTX 3060ti when mining RVN and ETH, you want to absolutely overclock reminiscence and decrease core clock as a lot as attainable.

It relies on reminiscence overclocking: you will get 31 MH/s at a reminiscence clock of 8200 MHz.

For a similar purpose twin mining on GPUs with out LHR is ineffective. Mining RVN+FIRO, RVN+ETH, RVN+ERGO, and so on., on the identical graphics card can’t deliver you extra revenue than mining one coin at a time.

Conclusion. Is Ravencoin Mining Worthwhile?

At present RVN mining is already among the best mining choices apart from Ethereum. Contemplating upcoming adjustments attributable to Ethereum’s plans to desert GPU mining, Ravencoin mining will be thought-about a promising different. Plus, Ravencoin affords a variety of choices to determine the specified mining vitality effectivity even inside one GPU mannequin.

It’s unknown how a lot time is left till Ethereum absolutely shifts to PoS. However it’s best to already begin checking how nicely your graphics playing cards can mine different cash and studying extra about probably steady hash fee/efficiency ranges for various overclocking settings.
