    Entry level mining while not gaming. 3070/2070 rig, planning to add 2 more.

    Thanks /gpumining

    Found this guy online selling Gpu holders made by him with a 3d printer for mining. For 6 eur each I decided to give it a go and I'm very amazed with the quality of it. Also prepared to put a 120mm fan in the front. Screws included. Cheers guys

    Mining with Tesla M40 in 2021

    Posted: 28 Sep 2021 09:45 AM PDT

    Has anyone one here been able to successfully mine anything with the tesla m40s and get good rates? I spent a lot of time searching but found no definitive answers. I understand it has a tlb limitation but has anyone found a workaround?

    Thanks in advance.

    Why don't we as a GPU mining community choose the next coin were going to throw our processing power at? Instead of our faith being decided when it happens. What's the community's best choice?

    Posted: 28 Sep 2021 05:00 AM PDT

    I mean to say… As a community we are commodity by working as a group find the projects that want us. I'd love to see a change of the reward structure for node length of on time :-)

    What's her best option will project would benefit best from a concerted opening of their processing power!

    We all saw around the curve before everybody else to get to this point…!!! What should be our next move I am up for ideas.

    Thanks

    Finally, first rig up and running, 4x3070tis, (3x inno3d ichill, and 1x msi supreme x), 56mhs each, averaging between 226-227mhs Total, -lhr 68, combined with 3080 non lhr in my gaming pc getting 327mhs, I want to build another one now ��

    AMD 6700XT - Adding Thermal Pads and Heatsinks. Mem temps from 104 down to 78.

    Posted: 27 Sep 2021 11:54 AM PDT

    Recently got a couple of 6700XT's and I immediately noticed severe memory overheating problems. The memory temps shot up to 104-106C within a minute of mining and thermal throttled from 46MH/s down to ~25MH/s.

    Having seen other posts regarding improperly placed or even missing thermal pads, I bought a set of gelid 2mm pads and some heatsinks.

    Surprisingly, the reference 6700XT does not even have any thermal pads on the back for the metal back-plate. Something that Gamersnexus noted in their tear-down video.

    After the mod, problem solved. No more thermal throttling, and memory temps for both cards hover around 78-82C.

    Burned PCIE slot, motherboard safe to use?

    Posted: 27 Sep 2021 09:45 AM PDT

    Managed to be stupid enough to plug in the pcie riser backwards and melted the pcie slot.

    Is the motherboard still safe to use, the other slots?

    Undervolting your GPU in Windows for higher efficiency

    Undervolting your GPU in Windows for higher efficiency

    https://preview.redd.it/47w9ihevv3q71.png?width=1703&format=png&auto=webp&s=a8c1fb6c20125bf517664964c143ecc4cdb3fe78

    If you're mining in Windows, it might be worth undervolting your cards for better efficiency depending on the model you have. What I would typically do is let the card run with a simple curve offset e.g. -400 core and leave the power limit at 80% or so. Obviously the memory clock should be as high as it will remain stable. Read the core frequency that the card decides to settle at, then go ahead and pull the first dot on the curve editor up to just above the frequency you just observed. This should now cause your GPU to run at the same frequency, but at the lowest core voltage that Afterburner allows.

    Note: locking the frequency/voltage values with the "L" button seems to have a negative impact even though the card seemingly runs at the same values - YMMV.

    The card pictured is a Gigabyte 3080 Gaming OC, in a closed case in a ca. 20 degrees C ambient room. Card has been modded with 2mm gelid ultimate thermal pads. This card generally uses more power with like for like settings against some other 3080 models, as you can see in HWiNFO it is already at the lowest possible core voltage.

    How to decide what pool to mine?

    Posted: 27 Sep 2021 04:37 PM PDT

    New to mining, and new to the sub

    I got my hands on an RTX 3090 (Gigabyte vision model) and just mined ETH for about a week using T-Rex miner. My question though is how do you decide which pool to mine? Difficulty in the pool seems to be the main factor but do you switch pools every day based off difficulty?

    Side note: I still have my RTX 2080 & GTX 970 sitting aside. Was thinking about setting them up to mine in their own separate rig since my 3090 is just in my gaming PC . Any suggestions on what to mine / pool for those 2 cards?

    Cheers!

    How can I stop Z390-P from booting to BIOS?

    Posted: 27 Sep 2021 02:53 PM PDT

    I have the popular Z390-P that I have 7 RX580 cards on. It works wonders, but when it reboots, it always boots into (and stays in) BIOS. Unless I hit "escape" and "enter" it stays in BIOS.

    This isn't much of an issue when I'm around, but is a pain in the beee-hind if it reboots when I'm not around (or sleeping).

    I've gone through bios settings dozens of times to figure out why it does that but no luck. It seems when I have 4 or less GPUs connected it boots all the way no problem, but when it's booting with all 7 cards, it boots into BIOS and never leaves until I tell it to.

    I tried booting with windows off SSD and Ubuntu off thumb drive and the issue is the same.

    What am I missing?
