Topic: Guys! Got some questions about crypto mining (Read 209 times)

I also want to add that the new generation of video cards from all three vendors (AyyMD, Shintel, Neeveeeedia) will not be more memory-efficient. They will only be more core-efficient, which is only important to gamers. Memory bandwidth will not be improved by much, therefore hashrate will only be 10% better at the same price point at best. Remember that they will use the same ole' GDDR6X memory, which is power hungry.

I only expect GPU prices to fall significantly (> 20%) at the low end of the market (below RTX 3070 gaming perf.) thanks to Intel's Arc Xe cards. High end video cards should remain stable in price.

After PoS, LHR will be obsolete because it only affects the Dagger-Hashimoto algorithm.

ETH PoS will likely take place after mining isn't profitable anymore, I am looking forward to this in 6 months but there are other coins you can mine so you have nothing to worry about, RTX graphic cards are miners' favourite and will be so for a long time because they are the most efficient GPUs around, 80% of LHR is already unlocked and we might get better unlocking in coming months, very soon LHR will be something of the past.

Dual mine Conflux at 75% power limit to get 85-95% the profit of the FHR version

You got it backwards. FHR video cards would fall more in value than LHR. In fact, this has already happened. Here are the historical eBay prices:

RTX 3080 10GB FHR


RTX 3080 10GB LHR


If you bought the FHR version on January 1st, you lost 50% in depreciation (-$1000). You made $529 of mining profit at free power. Total return: -23.6%

If you bought the LHR version on January 1st, you lost 43% in depreciation (-$750). You made $476 of mining profit at free power on ETH & CFX. Total return: -15.6%

With ETH+CFX dual mining, the LHR card would have made ~90% the profit of the FHR version while only being 87.5% of the price. I just looked at feeBay for today's prices on the RTX 3080 10GB card. The cheapest FHR model is $1130 while the cheapest LHR model is $890. Why pay 27% more only to get only 10-15% more ETH-only profit than the LHR version?

This is exactly why I stick to LHR cards these days, with the threat of PoS. I care most about gaming resale value, not getting an extra 10-15% revenue on only one algorithm (that may be gone before the year ends). The #1 most important factor in mining, especially GPU mining, is the price change of the equipment.

The passage of eth to pos has been postponed i do not think it will take place before 2023, even if there are software that can unlock the lhr even by 77% it is better to buy those without limits, obviously the gpu will cost less when eth will no longer be minable

1. Nobody knows when ETH will finally move to the PoS algorithm, this has been getting postponed for years now and I dont want to make a move base on whether it's going to happen or not.

2. RTX graphic cards are a hot cake for crypto mining so the answer is yes miners are still buying this graphic card for mining, either LHR or non LHR many don't care, they have dual mining to save the day on LHR GPUs.

3. So far so good, LHR have been unlocked to 78% right now and I believe that in time this will get better, my RTX 3070Ti was mining at 48MH when I first bought it, now its at 63MH, the LHR unlock have become a success so far.

hehe..try to go vent in-vent out hunting first.

60000 btu is 30-40 amps at 220v, venting with industrial fans would only take 6-8 amps at most.

1. PoS of Ethereum has been postponed several times. I don't think it is going to happen anytime soon (this year, I would say). So no reason to be afraid. Furthermore, there are plenty of other coins possible to be mined instead - and you can still buy ETH with those mined coins.

2. RTX GPUs are still very powerful in mining, so yes

3. It is realistic that lolMiner and T-Rex latest versions are able to unlock 80% of the original hashrate. This is real and there is plenty of evidence in forums/youtube/etc. Moreover, you can also dual-mine on LHR cards

RTX 3080s are good for dual mining and now that lolminer have unlocked almost 80 percent of the locked power it a very good alternative at the moment but all still depend on how much they cost, very soon I believe this graphic cards will go back to MSRP.

Maximize profit with the RTX 3080 12G? This card can only be unlocked to 60% maybe? So you pay more for less hashrate than the normal 3080? 

Even while other graphic cards are losing value in my country this 3090s are still costly, thermal pad isn't a issue anymore if you can order for copper plates and replace them once and for all but price is a big issue right now, 2060 super, 3060s, 3070s are going down in value fast, even the AMD counterparts too.

some amd 6800 and 6800 xt are around 800 bucks. which okay.

I have been given an offer to buy four 3080 fe 95 mh for 1050 each.


have to buy all four which would be 4200 for 380mh.

its a pretty good price , but I passed on it.

My mining area is heat capped.

I have 20 empty 30amp/240 circuits ready to use but room is too fucking hot.

We may add a 60000 btu chiller. have to decide this week.

The biggest problem is it's overpriced. Get the RTX 3080L 12GB or RTX 3060L 12GB instead. That's where you will maximize profit:equipment price.

RTX3090s have no LHR lock 🔑  

The problem is this GPU is hard to cool down once the factory thermal pads are not strong anymore, if this is purchased by a newbie there will be problem about high temp later and newbies might not be able to fix them, its hard to cool a RTX 3080 and 3090s, go with 6700XT like FP91G said or RTX A2000.

Instead of 1 RTX 3090, buy 2 RX 6700 GPU. Now more people sell video cards than buy.

Once ETH goes POS graphic cards will be cheaper, if you aren't in the train of ordering new graphic cards I suggest you hold your horses for now, we can say that the merge may never happen and later it happened, I already bought all the GPUs I need and still sourcing for very few ones because I am in this for a long term.

Forget the POS merge on ETH network for now, its plagued with a few errors and problems so the team have postponed it again, it may happen by the year-end or never happen at all, if you really want to mine ETH or coins it's better to start with small graphic cards, those 3090s are a pain in the ass for newbies.

The newest estimate is Q4 2022. The lead PoS developer predicted that PoS would be deployed in Q3 2022 at the earliest. So yes, I would guess before the end of the year. However, PoS was supposed to happen back in 2016-2017. Miners panicked back then. But it has been delayed over & over again. So don't be surprised if the new estimate is 2023.

It seems to be that most medium-size GPU mining farms (50-500 cards) buy mid-range video cards like RX 5700's, RTX 3070's or RX 6700 XT's. However, the best investment is probably the RTX 3060L 12GB. Just dual mine ETH+CFX to get 45 Mh total. I have a rig of them and it has been my most profitable rig.

Of course, most n00b miners only buy equipment during a gold rush for inflated prices. I was dumb enough to open an ETH warehouse in early 2018. I bulk ordered RX 570 cards for $370 each. When ETH price crashed, profit didn't cover the rent. I defaulted on my lease and the business went bankrupt. I had to sell the cards for $90 at the end of 2018. Whoever bought those cards has made 3-5x their investment back.

The wisest time to buy video cards is right after the ETH PoS crash. The only problem, though, is you probably won't make any profit for a few years. Just HODL the coins, then when the next bull run happens; sell all your coins as well as the GPUs. This is exactly what I did during 2019-2021, and I made a killing. I bought GTX 1060's for $140, made $400 of mining profit, then sold them for $330.

70% is the average, although the actual unlock range can be 60-80%. I recommend dual mining on LHR units since you can attain 90%-95% the profit on the FHR version. Set the power limit to 70-80%.

First of all this is for the Altcoin mining section and not here,so most probably the mods of this section will move it but here are the answers you need to know.

1.No one knows,that is the minimum time it can happen but it may be postponed again in 2023,we are seeing such news since 2016 and are now in 2022.

2.Some are,whatever RTX they can afford,LHR or not,only the bold are doing this or those who have enough spare financial power,most people,normal miners aren't right now.

3.Yes some mining software have unlocked up to 77% and it is 100% true.

I am new to this forum, and would like to hear some opinions regarding Ethereum  mining and Nvidia GPU, specifically:

1. When do you guys think Ether will move to POS? Is it by the end of the year?

2. Are miners still buying RTX GPUs today? If so, are they only buying the 3090s with no LHR?

3. Also on LHR, I know there are several software that claim they can unblock it and get back 70% of its power. But realistically how true is this?

Thanks for all the colors!
