    A100 :)

    Posted: 22 Jul 2021 04:56 AM PDT

    Just testing 2x A100 at work to make sure thermals are ok in our server room. Nothing is better than mining for stressing temperatures.

    170MH per card on default settings ... with power draw circa 250W. What a beast !

    Is it possible to run a 3060 with the 470.05 driver and 3070ti on same rig?

    Posted: 22 Jul 2021 08:14 AM PDT

    Won't the 3070ti require an updated driver to mine when the 3060 needs the old beta driver to achieve normal hash rate? Curious if it's possible to run two different drivers on the same rig. And yes I know the 3070ti is lhr :/ Thanks!

    What prevents multiple pool mining?

    Posted: 22 Jul 2021 06:34 AM PDT

    If you're mining ETHash for example, and you're submitting "guesses" (shares) to some pool, and it could be anything from NiceHash to Ethermine to ProHashing, what prevents you from having your GPU do the Proof of Work and just submitting the same answer to every pool? Each pool would just see it as you submitting shares like you always do, and getting paid out PPLNS even if your share isn't the actual solution to mine the block. How does one pool know that you're not submitting the same results to other pools?

    Need guidance on first mining setup

    Posted: 22 Jul 2021 05:30 AM PDT

    Never mined before, but a friend of mine called me Tuesday morning saying that Best buy had RTX cards in stock. I wanted a 3080 FE for gaming, but they only had a 3090 FE left when I got there. The adrenaline clouded my judgement and I pulled the trigger. I figured I would flip it for quick profit but I didn't do enough research and it seems like the prices are coming down close to MSRP now. Feels bad man to be a bag holder LOL. That's what greed gets me I guess.

    Now, I'm thinking I will start mining with the card seeing as the flip profit isn't so lucrative. I have a couple older PCs and I'm wondering if either of them will be sufficient to act as a mining rig to host this beast of a GPU. The first PC is a i5 3570k on a z77 mobo w/ 8GB DDR3. The second PC I have is a Pentium G3258 on an unknown mobo w/ 8GB DDR3. I know they're both ancient machines, but will they hold me back for mining? If so, are there any recommendations for minimum requirements for CPU/mobo/RAM so as not to constrain the MHs I can get out of the 3090?

    Can I use 2 different geforce gpus for mining?

    Posted: 22 Jul 2021 07:11 AM PDT

    I've got a 2080ti and a 1080ti. Wondering if I could use them in the same pc for mining? Also would I need an sli cable?

    Phoenixminer arguments 3080

    Posted: 22 Jul 2021 05:48 AM PDT

    Hey group, did some google searching and reddit searching and can't really find an answer.

    Running Phoenixminer with my 3080 and unsure what, if any, arguments I should include in the Bat file. I had the original arguments in there but have realised they are got 4GB cards so have taken them out. I am OC using afterburner so I don't need those either (side question: although I like the idea of not needing to change the profile before mining…can it be programmed to go back to a original settings when closed or paused?)

    Any suggestions on arguments or should I just completely go through the arguments noted in the Doc and add anything that applies?

    Help - RTX 3070 Laptop 22 MHs max :(

    Posted: 22 Jul 2021 05:44 AM PDT

    Hi guys,

    I recently received a gift the latest Razer Blade 14' with RTX 3070.

    I use a MacBook air for my daily laptop needs and I have a PC for my gaming which outperforms this laptop by far. So I thought I would put it to good use (I cant sell it as it would offend the person who gifted me with it), so I decided to mine.
    I have been tweaking it all over the place, overclocking it etc.. for the last week but still cant get it to over 25Mhs.

    Does anyone here have anybody here able to help? Thanks in advance!

    Disaster recovery loan for farming due to loss in revenue

    Posted: 21 Jul 2021 10:50 PM PDT

    Would I qualify for federal loan/grants since due to extreme heat my yield (hashrate) fell, had shutdown farms(mines) , crop withered (thermal pads became oily), fire damage (gpu risers burnt out)?😇😎🤪

    I have a i7 9700k, z390e 4*8gb with a 2080ti xc ultra and was wondering if I can add my 2070 super xc to it with my evga 750watt supernova gold psu? This is for mining ofc

    Posted: 21 Jul 2021 05:30 PM PDT

    So I've checked out a few sites and the values given vary wildy pc part picker won't let me chose a different gpu so two 2080tis will yeild 702 Watts while another says 680 Watts, thing is I run my 2070super at max 110 Watts while mining. And plan to game on my 2080ti in the day and have them both mine at night. I'm using trex miner.

    Is this safe? If I load my psu too much when switching OC profiles what will happen if it gets over loaded? Will it ware out my pus by loading it with supposedly 700 Watts (should be less in application) if I don't have clearance in my case I guess I'll have to use a riser cable/stand.

    Any advice or clarity on this would greatly be appreciated, still very new to mining and what not, I'm just doing this cause its fun. And gonna get cold where I live. :D

    Temps low, hash high. ~

    Looking for advice and tips for mining eth with a 3060

    Posted: 21 Jul 2021 06:05 PM PDT

    I just recently got into mining after finally being able to buy a 3060. Currently, I'm using nicehash to mine bitcoin, but I'm more so interested in mining ETH until it switches over to pos. Just curious if this is an option?

    Also, from what I understand about nicehash, I'm not actually mining bitcoin, I'm selling my hash power so nicehash can mine eth? Am I understanding this correctly?

    Is any one adding more cards to their rig now?

    Posted: 22 Jul 2021 12:45 AM PDT

    Used 3070 are under 850 here and I can add up to 4 more cards with that add2psu thing but last month I loaded up on 3070s at 900, I would've came out ahead if I waited until now to buy the cards. I didn't mine $50 of profits yet and prices dropped by $50 or more since I got them.

    Asrock b560m pro4 2 GPU’s

    Posted: 21 Jul 2021 11:43 PM PDT

    Anyone know if I can fit two gpus in this one it doesn't seem like enough space and the small pcie is under the card so I can plug in a riser , can I use the pciex16 to plug in a riser meant for the small pcie ? Or what are my options? I want to add another card

    A different rig design...

    Posted: 21 Jul 2021 01:36 PM PDT

    A different rig design...

    I started to mine RVN with my old RX580 in April. For many months I learned about hiveos, risers, miners and other crypto-related stuff. That period was a practice for me before jumping to a 13x3070 setup. I live in the Mediterranean and summers are really f*king hot here. It can easily reach 45 Celsius during midday and nights are around 25-30. So thermal throttling could be an issue for me. That's why I designed this setup. I believe there is enough space between cards so they can breathe easily. Cards are attached 1 to the left 1 to the right so they don't heat up each other too much. I also made a small platform to raise the motherboard due to the cable length. Currently, the fans are around %70 and temps do not exceed 65 Celcius. Right now it's night and with the open windows only (no additional fan for airflow) I have 65 Celcius with %50 fan speed. I even have a card with 56 Celcius with %30 fan speed. The next steps will be:
    1) Marking the positions of the cards to screw them to the frame instead of using zip-ties.
    2) Securing motherboard and PSU's to the table
    3) 3 RTX 3070s will be added
    4) The motherboard rising platform was supposed to be an adjustable one but I was so sleepy and tired (plus lazy) to dig the holes. Maybe I will do it later as well.
    5) Adding a panel on the front for reset & shutdown buttons and USB ports.
    6) I bought 10 Aigo PMW fans (cheap sh*t from Aliexpress). I need to 3d print proper attachments to install them. Plus I'm planning to buy fan controllers.

    I would like to have your opinions and ideas for improvements as well!

    PS:
    1) I don't need to worry about space. I'm only concerned about the heat.
    2) I love welding and it was a good weekend practice with my dad. The upper frame was all recycled iron laying around and I only bought the wood and 2x 6 meters iron profile.
    3) Yes the photos suck
    4) I'm aware that this build is in the "ROI: NEVER" category.

    Finished rig. The next goal is to remove the zip ties and mounting GPUs properly with screwdrivers

    The table below the main GPU frame and motherboard platform.

    The gap between the table and the motherboard platform provides enough space to connect two PSU's and it is a resting place for modem and other possible stuff.

    Naked frame.. I was so tired that I couldn't take the photograph of the whole frame..

    The complete functioning rig.. with ugly zip ties..

    3 RTX 3070s are on the way to completely fill the H110 Mobo

    Anybody mixing LHR and non-LHR on the same rig/mobo?

    Posted: 21 Jul 2021 08:50 PM PDT

    I have a couple cards laying around, 1 is LHR and the other isnt. Wondering what the most profitable solution is here as I'm assuming we can't run multiple different algorithms with cards that are on the same mobo? Thanks so much

    Does anyone have experience using 1 to 4 PCIe expansion cards on HiveOS?

    Posted: 21 Jul 2021 08:47 PM PDT

    I want to use this expansion card i bought on my BTC-37 miner, as i understand its a plug and play device if the necessary drivers are present but thats the part im scared about. The CPU on my board can manage 32 1x PCIe lanes, but does linux based HiveOS have the necessary drivers so i can use it?

    Worst case ill switch it over to windows and use minerstat.

    What’s the advantage of mobos with multiple pcie 16 slots?

    Posted: 21 Jul 2021 02:20 PM PDT

    As title says, what's the advantage of a mobo (like the btc-s37 for example) with 8 x pcie 16 slots, when all you need is 1 pcie 1.0 slot, risers, and a 4x splitter to run 4 cards on that single slot? You could theoretically run the same number of cards (8) with 2 x pcie 1.0 as you could on a btc-s37? Thanks!

    What parts should I watch for when people start dumping?

    Posted: 21 Jul 2021 09:46 AM PDT

    I wasn't around for the last crash, but I started mining with my personal hardware around January. I've really enjoyed the hobby so far, and I'd like to build an actual rig when everything dies down.

    With the current market, it's hard to tell what's a good deal and what isn't. I have to keep reminding myself that a year ago, a RTX xx60-level system was around $1000, not $1500 like it is now.

    What parts should I watch for on the second-hand market (Craigslist, FB, OfferUp, etc) and at what prices?
