    Abnormal consumption 3060ti

    Posted: 19 Jul 2021 05:16 AM PDT

    I was wondering if anyone ever had this kind of problem.

    I've been mining with a 3060ti since feb/mar and the card always did a good job. My settings (afterburner) were:
    - Power Limit 58% (115w)
    - Core clock -500
    - Memory clock +1200
    - Fan 55~60%
    - Temperatures always stayed on 50~60°C (core).
    - 61MH/s

    Now when I try to mine (t-rex) with above settings, core clock stays on 200Mhz~350Mhz top. If I push the memories down to +0, the core clock goes up a bit. Looks like some self imposed power limitation. Now I have to use other settings to achieve 57MH/s@140w (power limit 71%). Looks good on gaming, even so the performance seens a tiny bit bellow some 3060ti (superposition 1080p extreme ~6700 points).

    Now, I was looking for it's power consumption and the card is chugging a lot moar power in idle, without anything connected, just sitting in idle (screenshot attached).
    My guess, since I made a whole lot of tests if that something is wrong on the card or the gpu chip itself. Does anyone have some guess if it's a mosfet/vrm/something related?

    Of course I made a lot of testing before posting:
    - Other motherboard/slot
    - Other PSU
    - Other drivers
    - Repaste, even if doesn't looked like temperature problem (at least on the core)
    - Anything else that is more common, since I have some knowledge about hardware

    TL;DR:
    - 3060ti was mining at 61MH/s@115w
    - Suddenly I needed to tweak to 57MH/s@140w, otherwise, the core clock dropped to 200~350MHz
    - Made a lot of tests with different motherboard, drivers, OS etc
    - The card consumption in full idle is too high
    - My guess is that it's something hardware related, but I have no idea what (vrm, mosfets etc)
    - I was hoping that someone with advaced eletronical knowledge would give a opinion (idle consumption screenshot attached).

    Oh did difficulty drop? I wonder why. Maybe some ASICs went off line. (Saw this video and it both hurt and made me smile)

    3080 Still Throttling After Installing New Pads

    Posted: 18 Jul 2021 10:44 PM PDT

    Hey everyone, before I posted this I tried looking for answers, but couldn't find anything. Basically the EVGA 3080 I had was throttling before I even changed the pads. Temp was running 108-110. I was getting a hash of 45-50 mh/s. So I figured, I changed the pads. I ordered the 1.5mm pads. Although it definitely is cooler, it doesn't help that the memory junction temperature still is hitting 108-110. And it's still the same hash. I also have another 3080 on the same rig that's pushing 96 mh/s. Any suggestions?

    ASUS PRIME B460-PLUS - 4G Encoding?

    Posted: 19 Jul 2021 07:13 AM PDT

    Recently purchased this board and setting it up for a 6 GPU mining rig - I can't seem to find the setting for 4G Encoding...

    Am I blind or is this not a board that supports despite the numerous PCIe slots? Any help would be appreciated!

    My First Mining Rig. Pretty Excited!

    Posted: 19 Jul 2021 12:18 AM PDT

    My First Mining Rig. Pretty Excited!

    I just finally put together my first complete rig with 6 GPUs, needless to say, it was a pain to finally get this all put together but after days of messing around with clocks and the cards, I finally got a good stable hashrate.

    My Specs:

    • x3 Sapphire Radeon RX 5600 XTs 8GB
    • x1 Sapphire Radeon RX 580 8GB
    • x1 MSI Radeon RX 580 8GB
    • x1 ASUS Radeon RX 580 8GB
    • EVGA 1000w PSU
    • B450 Pro4 ASRock Motherboard
    • 12 × AMD Ryzen 5 1600 Six-Core Processor
    • 16GB RAM

    I'm currently pulling a steady hash of 215 Mh/s with a little under 600w of power running HiveOS using TeamRedMiner.

    The only issue that I currently have is the ASUS Radeon Rx 580 that's pulling a temp of 75c. I have fan speed set at 85% due to this. However, it still stays at a steady 75c. Is this a high temp for that GPU?

    Afterburner going back to stock after 30-60 minutes

    Posted: 18 Jul 2021 09:01 PM PDT

    I'm mining on a 3090, getting about 125Mh. It's mining with 90% tdp, +1370 mem and -50 core, but after a while it seems that Afterburner going back to stock settings even if the settings look the same, but mining drops to 107Mh. If i adjust anything, like -51 on core it starts mining at 125Mh again for a while. Any idea what it might be?

    Gigabyte RTX 3080ti Eagle Thermal Pad Replacement

    Posted: 18 Jul 2021 03:26 PM PDT

    In case anyone is wondering pad sizes and how much temp difference it makes swapping thermal pads on their Gigabyte 3080ti eagle these were my results.

    Used Gelid Solutions Ultimate Thermal Pads:

    Back Plate is 3mm pads

    Front side around GPU chip is 2mm

    Rest of pads 1mm

    Used Kryonaut Thermal Grizzly Paste

    Tested on KAWPOW before replacement

    VRAM Temps - 110 degress Celsius getting 51 M/hs

    after pad replacement

    VRAM Temps - 84 degress Celsius getting 58 M/hs

    Is it possible for me to know how much power is drawn from each 8pin cable and from the slot/riser itself?

    Posted: 18 Jul 2021 09:42 PM PDT

    besides the known numbers, is there a way to see live how much power is drawn from each input? (how much W the card is currently using and from where is he taking it?)

    Why is the Gigabyte eagle AIB so cheap?

    Posted: 18 Jul 2021 07:18 PM PDT

    I ask because I have grown used to AIBs costing at least a few hundred dollars more than the FE card. am I overlooking something stupid?

    Is the Gigabyte just drastically lower quality silicon? How does this work?

    Getting extremely low hashrates (3mh/s) on a 980ti while im supposed to get around 22 mh/s

    Posted: 18 Jul 2021 06:46 PM PDT

    Hey , im a small miner just trynna mine with a 4 year old paper weight and im trynna mine some eth but for some reason , every other algo other than ethash gets normal hashrates but for ethash , i barely get 3 mh/s . Tried everything from trying more than 10 drivers from different times. Turned on "optimize for compute mode" but that doesnt seem to do anything . And i had a feeling that its an issue with windows not turning the option on , so i tried to mine linux but then i have no idea on how to turn on the optimize for compute performance in linux since they do not have nvidia control panel. Pretty much in short tried everything that came to my mind , Please do share any answers. (and yes before yall try to bully me for having a 980ti , ik its old but its supposed to get around 20mh/s and also it does have 6gb vram)

    Your aglorithm of choice & pool

    Posted: 18 Jul 2021 02:11 PM PDT

    I started w nicehash then went to phoenix with ethermine for eth for 3 months but now ive been using trex for roughly 3 weeks because of the CLI and better performance.

    For rvn I use phoenix but pool of 2miners because I havent transferred over to trex yet nor tested it because of time restraints.

    What are your go to algorithm(s)?

    Hashrate of my cards

    About Psu and OS

    Posted: 18 Jul 2021 02:29 PM PDT

    I know that there are several Tutorials online, but sometimes a read contradictory things and before I burn my house down I what to make sure. So here a few questions.

    As far as I have understood it, one has to connect riser and Gpu always with the same Psu and not riser with one and gpu with a different. Right now I connected my Maninboard, fans, 5 gpus, and 5 risers with one Gpu. The other PSU powers the other 5 riser and gpus.

    Is it ok to just short the 2 connectors from the 24 pin on one Psu wich is Not connected to the Mainboard or do I need to bridge the second Psu to the first one? Sometimes I have read that there has to be a resistor between those two pins. Or maybe short them on both psus so they both are always on?

    Is it OK to connect for ex. a 3080 wich needs two 8 pin with one 8 pin through using a Y splitter and connecting the riser then to a different 8 pin?

    And in addition I am looking for a new OS what is your excperiance? Most importantly for me is of course performance. Do they all perform the same? Right now I am using t-Rex on windows. I know, that there are a lot of pretty looking OS wich are specialized for mining and have a good GUI (like Rave OS, Huve OS,…), but the are cost monthly. The only free one are Linux (I guess Ubuntu is the best) and Windows. But they are Limited to 12 gpus. Is it possible to still somehow use 13 ?

    Thanks in advance.

    anyway to make a 6 gpu board mining rig into 8?

    Posted: 18 Jul 2021 11:49 AM PDT

    my board is h81 pro btc r2.0 (6 gpu slots)
    i'm using 2x1000w evga with add2psu (each evga has 3 gpu power cables)

    anyone successfully in adding 2 more gpus by splitting pci and power?

    I always thought 1 power cable per gpu, but I also seen people with 3 gpus 1 power cable? lol

    Mining motherboard recommendations for gaming/decent resale?

    Posted: 18 Jul 2021 08:12 AM PDT

    Hey everyone. Just curious if you all have any suggestions for a decent mining mobo that could be used in a regular pc build for gaming/productivity or resale once POS happens. Would only need it to take 4 cards, 6 at most. Thanks!
