Video Card Overclocking for Ravencoin (RVN) and FIRO Mining


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 thought-about sizzling. It closely depends upon 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) Exhausting Fork. New Algorithm – FiroPoW. Easy methods 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 ideas are the identical for each. Although this text is about RVN mining, you possibly can simply use it to overclock GPUs for FiroPoW to mine Firo.

Easy methods to Overclock GPUs for Ravencoin Mining

If you wish to overclock your video playing cards, try to be able to experiment. One of many elements to contemplate is the price of electrical energy. Other than the common optimum overclocking parameters, we are able to apply laborious undervolting that leads to solely 80% of a mean hash charge however decreases GPU energy consumption by 33–39%. And we are able to virtually at all times do the opposite: acquire 10–15% of hash charge however enhance energy consumption by 22–30%.

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

For instance, the RTX 2070S may give out 17.05 MH/s consuming 89 W (5.22 W per MH/s), however it will possibly 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 possibly can even overclock this graphics card to 26.05 MH/s consuming 209 W (8 W per MH/s). On this case, a superb GPU cooling setup is a should.

Within the desk beneath you possibly can see among the most attention-grabbing overclocking eventualities and RVN mining hash charges on completely different NVIDIA graphics playing cards.

We used T-rex 0.24.2 to get the information. We’re going to replace the desk after we take a look at 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 charge. So you need to overclock the whole lot. But when you’re going to overclock unexpectedly, you received’t know the place the issue is in case your GPU turns into unstable.

So you need to overclock step by step.

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 value. 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.

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

One other necessary factor to recollect is that you simply don’t must activate the tablet for the 1080 and 1080ti. At a set PL charge it received’t offer you further hash charge, however it can destabilize overclocking.

Step 2. Core overclocking.

If you happen to mine utilizing Home windows, set the core voltage in MSI Afterburner. It is going to make overclocking extra steady and enhance the max power effectivity.

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

When you have a multi-rate electrical energy meter and also you wish to mechanically change to the chilly mode at a better electrical energy charge and overclock GPUs at a decrease electrical energy charge, you need to overclock the core in all set factors.

You need to begin with the very best voltage level. Do not forget that the upper the core voltage the much less you possibly can 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 you need 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

Trendy GPU reminiscence can simply retailer the information wanted to mine two cryptocurrencies on the similar time. Nonetheless, they might compete towards one another for reminiscence and core, so the ensuing hash charge would principally rely on the depth of every algorithm.

Observe that Home windows 10 consumes extreme GPU reminiscence quantities on all GPUs. Twin mining is unattainable on GPUs with solely 8GB of RAM, however it’s potential when you 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 this planet, 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 may give out even 42–43 MH/s. When mining Ravencoin, you may get 21 MH/s at a decrease consumption charge of 121 W and 26 MH/s at a better consumption charge of 200 W.

If you happen to dual-mine algorithms with completely different depth, you may 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 at all times get extra revenue when you mine only one coin – Ethereum. It additionally consumes a lot much less energy.

Observe that we used completely different mining applications for testing in order that we might regulate the depth of every coin. The ensuing values may not be the very best potential.

When you have LHR graphics playing cards, in idea you possibly can strive twin mining, despite the fact that you received’t see a major enhance in revenue. This selection solely is smart in case your electrical energy charges are low.

RVN Mining on Nvidia RTX 30хх

As you possibly can see, RVN mining hash charge is often half of that of ETH in megahashes.

The RTX 30хх sequence, in addition to the 20хх, characteristic extraordinarily quick reminiscence that may transmit massive quantities of knowledge 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 measurement remained the identical. So it’s doesn’t make a lot sense to overclock the core: RVN mining hash charge on the 3070 can’t go above 30–33 MH/s. However, energy consumption will go up. So to realize the utmost power effectivity on the RTX 3070 or RTX 3060ti when mining RVN and ETH, you should absolutely overclock reminiscence and decrease core clock as a lot as potential.

It depends upon reminiscence overclocking: you may 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 this time RVN mining is already among the finest mining choices moreover Ethereum. Contemplating upcoming adjustments on account of Ethereum’s plans to desert GPU mining, Ravencoin mining could be thought-about a promising various. Plus, Ravencoin affords a variety of choices to determine the specified mining power effectivity even inside one GPU mannequin.

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