    Started with one card ... now at 834MH/s

    Posted: 13 Jul 2021 09:42 AM PDT

    Used my desktop to mine ETH for a few days, am now getting intermittent crashes. Black screen, USB peripherals turn off, only way to reset computer is switching PSU off.

    Posted: 14 Jul 2021 12:23 AM PDT

    Specs

    Windows 10 LTSC 2019

    PSU: corsair RM650i

    GPU: gigabyte 3070 Gaming OC 8gb

    Mobo: Gigabyte GA-B550 Auros Elite v2

    CPU: AMD 3600

    RAM: Corsair Vengeance LPX DDR4 3200 C16 2x16GB

    First crash happened when I forgot to stop mining/reverse Afterburner undervolt/memory overclock and played some LoL. Since then it has been crashing in the same way a few times a day, seems to happen most often when I'm doing very little, just using a browser and Spotify, often when I open a new tab or reposition a window. After a crash it usually wont post for some time/some amount of attempts to restart/reset CMOS. I've reverted to stock bios (previously had a light overclock on CPU and RAM), installed my old 75W GTX1050 (this seemed to reduce the frequency of crashes somewhat, hard to know for sure) and enabled max performance power management in Nvidia settings (found some other reports of similar problems that seemed to be related to power management of GPU in standby scenarios).

    The PSU is a ~4 years old, and if I'm maxing out everything with 3070 installed it might be near it's limits, but most games I've played seem to be bottlenecked by the CPU so I don't think I'd ever be drawing 225W for the GPU for long At the time of first crash power limit was set to 50% in Afterburner, and since then I've reverted to stock but not pushing either card at all. I've been powering the 3070 using a daisy chain 8+6 PCIE cable.

    What do? Next steps I plan to take are borrowing a known-to-be-okay 750W PSU, and installing fresh Windows Pro (LTSC is known to have it's own issues with drivers)

    RTX 3090 FE thermal pads and paste replaced + lessons learned + results

    RTX 3090 FE thermal pads and paste replaced + lessons learned + results

    ​

    NZXT H510, RTX 3090 Founder's Edition, Intel i9 10900K, Gigabyte z590 Aorus Elite, G.Skill Trident Z Royal 3600mhz, EVGA Supernova 850w G5 Gold

    Got a pre built computer from NZXT that has an RTX 3090 Founders Edition. The main purpose of the computer is for gaming but with etherium mining being hot, i figured I would mine some etherium when i'm not gaming. I maybe play once a week at best so it's mostly just a mining computer for now.

    Soon as I started mining, i realized the memory junction temps were through the roof at 110 degrees celcius! There is no way I wanted to let it mine with those temps, so I ordered the Odyssey 1.5mm thermal pads to try the thermal pad mod. I was hesitant on opening up the card but with so many people having success, I figured, how hard can it be? lol.

    After a few hours, I had thermal pads replaced along with new thermal paste (Thermalright TF8) for the GPU. Fired it up and my memory temps were stable around 98-100c. The gpu core was at 65-67 degrees and my mining rate was around 118 MH/s. I thought that was pretty good but my gpu temps went up. I wasn't too happy about that. I waited 2 weeks thinking that that paste may need to cure a bit and might improve but it never did.

    I took the card out and opened it back up again to re-apply thermal paste again. This time I ordered Thermalright TFX. When I took the PCB out to reveal the thermal paste, I realized it didn't squeeze out at all like the factory paste when I first opened the card. When i had applied the TF8, I had spread it on like I had previously done on CPUs. Big mistake. Apparently the pressure on the GPU isn't as high as coolers on CPUs even with the screws tightened all the way. This time, I applied a lot more thermal paste using the X method. Put the card back together and the GPU temps were in the 55-57 range. Thats a 10 degree improvement!

    Unfortunately I made a dumb mistake when putting everything back together. I firmly pressed on the card cover plate to make sure "everything was tight". That caused the plate to flex a little. This flexing indented the thermal pads and since the pads don't inflate again after being pressed, it must have left a gap between the plate and the thermal pads. My memory temps were back to 110.

    I ordered pads again, this time I got the Gelid 1.5mm Ultimate pads because they had a slightly better thermal conductivity rating than the Thermalright Odyssey pads. Took the card apart for the 3rd time and noticed the thermal compound just barely squeezed out from all sides similar to the factory paste. That was a great sign, since I must have applied just the right amount of paste. I put the new pads in place and fired up the card again. I made sure to not press on the memory pads at all! I simply screwed everything nice and tight without pressing down on anything. Memory temps were in the 94c range while the GPU was still a cool 55-57 degrees. Success!

    One more thing to mention, when applying thermal pads, make sure they're not oversized, specially near the edge where the cover edge sits. If the edge of the cover sits on some extra thermal pad, it won't apply proper pressure on the thermal pads that are over the important areas. I've included pics of how much thermal paste I put on the GPU along with the thermal pad layout on both sides.

    I also read somewhere that you shouldn't cover the resistors (R005) with thermal pads so i avoided them when applying the pads. Not sure the reasoning behind this but I figured its not something that gets unnecessarily hot so I made sure to avoid them. So far everything is working as expected.

    Thermal Paste: Thermalright TFX on the GPU (X application method)

    Thermal Pads: Gelid Ultimate 1.5mm

    Memory Overclock: +1100mhz

    GPU Overclock/Underclock: 0mhz (Underclocking made zero difference on power draw but caused instability with cuda core occasionally crashing)

    Power: 83%

    Memory Junction Temps: 96c

    Power Draw: 290 watts

    Efficiency: 415 KH/w

    Fan Speed: Target 62c GPU core (Results in 50-55% fan speeds which keeps things silent!)

    Mining Rate: 120.5 MH/s

    I recommend starting with a +1000mhz clock on the memory and bumping it up 50mhz a day if you're not crashing. I saw some minor instability when going over 1100 so I stopped there. You might max out at +1,000 or get lucky and reach +1,300 without crashing. Keep an eye on your MH/s to see if you're actually getting a difference in your mining rate with each bump in memory clock. The mining rate delta is very small with each 50mhz increase. For example, at +1,000 memory clock, my mining rate is 119.1 MH/s which is only 1.4 MH/s lower than at a memory overclock of +1,100. In the end, stick with the clock speed that provides you with the most stability. This isn't a sprint, its a marathon.

    I set all my overclock settings (fan, power, memory, gpu, etc.) in the t-rex config file just to keep everything in one place. This also basically sets the clock settings only when the miner is running so I can just turn the miner off and game with the factory clock settings. Targeting a GPU temp of 62c keeps my fan speeds at about 52%. I think this is great considering I have an nzxt h510 case which isn't the most airflow friendly case. The computer is in my bedroom and is dead silent. Its rock solid with no GPU crashes or reboots for days.

    TLDR;

    - Use more thermal paste than you think you need and don't spread it!

    - Don't press on the thermal pads when you lay them on the memory chips

    - Don't press on the cover when you're putting the card back together. You don't want to indent the thermal pads more than what the screws are doing already.

    - Don't underclock the GPU core, its useless when mining etherium and can cause instability.

    - Don't oversize the thermal pads.

    Graphics cards are like tattoos as soon as you get one your already looking/planning the next one.

    Do you have to replace gpu thermal paste every time you open the card.

    Posted: 13 Jul 2021 10:58 PM PDT

    Pretty much title. If I put the wrong size thermal pad and I open it again to replace it do I have to redo the thermal pad every time I open it?

    What times do AMD cards drop?

    Posted: 13 Jul 2021 08:28 PM PDT

    Does anyone know what time AMD cards drop usually? or is it completely random. Hoping to get a rx6800 xt at msrp but I dont know what time they drop. Thanks!

    MSI Gaming X Trio 3090 Waterblock idea?

    Posted: 13 Jul 2021 10:45 AM PDT

    I put heatsinks on the backplate of my 3080 FTW3 and the temps INCREASED +- 1c?! Any guesses why?

    Connecting rig via Ethernet to wifi extender?

    Posted: 13 Jul 2021 01:20 PM PDT

    Hey all, I'm new to mining and I'm trying to setup my rig. My router is in a place where I cant put my mining rig due to noise and lack of space. I have to have it upstairs in my room where there is no access to the router. Is there anyway I could use an Ethernet cable from my wifi extender to plug into my rig? Will this work conceptually? And if it does will I run into any rejected stale shares due to latency? My extender is right above my router on the next floor. Sorry if this is a dumb question but I can't seem to find anything in the forums.

    Rx570 8GB Crashes After Dag Gen

    Posted: 13 Jul 2021 12:46 PM PDT

    Anyone have ideas for this one? spent all of yesterday and most of the night before on this....no dice.

    problem:

    bought a graphics card with no video output but was capable of being put under load. I assumed it could have been an incorrectly flashed bios or maybe the card really was messed up physically but I could at least mine it on the cheap since I got it for $130. Got the card in the mail, tossed it in the rig and it worked fine. Anyway, I went to mod the bios with PBE but when flashing the rom back accidentally unlocked the ROM first (like for my 5700) and it bricked the card, etc. I got it back to the stock bios it came with (I also had someone track down copies of possible stock bios for this model of XFX 570 with micron ram) and rebooted into windows, ddu, reinstalled drivers and now when I go to mine the second that card finishes DAG file generation and begins mining the system locks up. It gets some sort of blue screen error regarding driver failure, VideoTDR failure, ATIKMDAG.sys, Thread stuck in device driver (commonly this), etc. This is specific to this 1 card in this rig so far

    what ive tried:
    -DDU, New drivers, and I've tried many versions -AMD removal utility then drivers multiple times -updated windows -updated motherboard bios -Set PCIE to legacy instead of UEFI -Tested if its related to the riser its plugged into, nope another card mines fine in it -Reset windows from within itself (this is what I've done short of full nuking the drive and fresh installing) -Plugged this card into my normal pc along with my fury (it got really wonky and I was unable to see my normal card in the amd software, but I could force the 570 to mine VIA nice hash miner and forcibly starting algos on the card, however TRM would not take device commands to launch that card (GPU1) over the fury in the system (GPU 0) but I guess this could just me being unfamiliar with TRM. (but important part is it successfully mined and benchmarked) [note: I believe windows installed drivers over my old amd ones, when I pulled the card I had to reinstall radeon software for my fury but it was working fine the whole time]

    I am at the end of my rope here and I come to you for potential ideas if anyone has them

    Edit: I have also tested mining all 3 cards at once or simply the card causing the crash and it persists both ways
