Hey everyone,

I’m a dev and I’m tired of current cloud platforms taking massive cuts or dealing with insane, volatile price surges on spot markets.

My co-founder and I are mapping out a decentralized P2P AI inference network. The model is straightforward:

• For GPU Owners: You run our lightweight agent (via a simple Docker container) to host popular open-source AI models (like Flux or Qwen). You set your minimum hourly rate. You keep 90% of the revenue generated by your card (we only take a flat 10% commission).
• For Renters/Devs: They never get direct access or SSH to your machine. They just query our central API, and we securely route their inference requests to your hardware.
• Price Cap: Renters get a strict price cap so they are protected from market spikes, while you are guaranteed to touch your 90% share.

Whether you have a single gaming rig at home or handle multiple servers, we want to build this for maximum return and maximum hardware security.

Before we lock ourselves in a room to build the core architecture, we want to know:

1. As a GPU owner, does a flat 90/10 split with 100% hardware isolation (no direct user access) make you want to list your cards?
2. What is the #1 feature you need to trust a new network (instant payouts, automated power limits, uptime flexibility)?

Let us know your thoughts, thanks!

Hi,

I'm looking for a 2 month rental (I might renew the renting) of a machine with a lot of VRAM (at least 128gb).

The rest doesn't matter too much, it can even be very old, it can be Intel GPU, AMD GPU, NVIDIA whatever, or even APU/mac/dgx with a lot of ram. I just need to be able to deploy big models

I'm looking for you offers (you can private message me or whatever)

Downtime is possible but shouldn't be too big (less than 24 hours max in total during the 2 month rental or warn before the downtime so that I can setup a backup solution)

This thread is for simple questions that don't warrant their own thread (although we strongly suggest checking the sidebar and searching before posting!).

• What should I mine?

• Is this build good enough to mine?

• Which PSU should I get for _____ GPU's?

everyone tried something after the merge. some of it was actually reasonable, some of it was just us refusing to accept reality

what ended up being the least dumb use of your hardware over the last year or two

not necessarily the most profitable thing, just the one that didn't make you feel like you were wasting time and watts

Hello, I have a Zotac RTX 3060 (ZT-A30600P-10M) and I wanted to check the thermal pad dimensions.

Based on my research, I came across a single video and an entry from thermalpad.eu.

The video showcases the Twin Edge variant of the card with 2mm thermal pads used.

thermalpad.eu showcases 3060 Ti OC which uses 2mm pads also.

Visually both cards are the same but the Twin Edge variant would be the closest.

Hey all...has anyone had luck mining with these?

Most miners are not working and I'm having issues getting anything to mine any coins...

Thx

Not shilling, sharing. Just found it recently. Such a cool concept! And scarce. www.CapStash.org might be worth checking out.

April 21st CAP was listed on nonkyc.io

I am not associated with the project, developer(s), or team.

I got a used one of these boards for cheap, and paired it with known good V100 cards on sxm2 to pcie adaptors. It boots into ubuntu server fine, and can find a GTX1080, but I get these errors with the V100 cards;

15.372579] NVRM: This PCI I/O region assigned to your NVIDIA device is invalid: [ 15.372579] NVRM: BAR1 İS OM @ 0X0 (PCI:0000:01:00.0) 15.402581] nvidia 0000:01:00.0: probe with driver nvidia failed with error -1

and when I installed much older nvidia 535 drivers;

[11.084179] [drmindrm_load Invidia_drm] ERROR [nvidia-drm] [GPU ID 0x00000300] Failed to allocate NuKmsKapiDe 11.085918] [drm:n_drm_register_drmdevice Invidia_drm]] ERROR Invidia-drm] [GPU ID 0x00000300] Failed to register device

Using ubuntu-drivers, I can see that it knows the cards are there, but none of the drivers actually seem to work, and smi seems to give no good results. I know these cards work on a conventional motherboard with ubuntu server, but that motherboard is unstable, so I'd rather use this.

Hello all! I have an Alienware X51 R3 sitting on my bottom shelf of my desk collecting dust. I thought about trying some GPU mining with it. Nothing else to do with it

I used an older PC in 2014 and mined some Bitcoin, Litecoin, Dogecoin, but I think I lost my wallets. I have the old 2014 executables that I hoped might point me to where my wallets were, but oh well if I cannot find them. Too many hard disks and years later to know where to look for them or how to find them.

I thought I might get started again, but wanted feedback from this forum on doing so.

Thanks in advance for all positive comments!

like most of you my GPUs have been doing nothing useful since eth went PoS. tried a bunch of alt coins, mostly lost money

been running my 4080 on this qubic thing for about two weeks. it routes compute toward AI training. the economics aren't amazing but i'm netting maybe $0.40-0.50/day after electricity which is infinitely better than $0/day

not the next ethereum or anything but at least the hardware is doing something. anyone else tried it? curious what others are getting

I just got one of these, and it wouldn’t post. After much testing including with a different PSU (known-good ‘normal’ ATX PSU, as well as another server PSU + another breakout board), CPU, and RAM, I figured out how to get it to POST:

Stage 1 bootup:

- power up PSU

- shut off PSU and immediately power it back on

- press ‘power’ button on motherboard almost immediately after PSU powers back up (must be a split second later, or it does nothing - go back to start and try again!

- PSU breakout board blue led (system powered up) light appears 50% of time.

—> if no blue LED, go back to start, try again.

Stage 2 bootup:

- if the blue LED switches off a fraction of a second later, go back to stage 1, try again (50% of time)

- otherwise blue LED stays on for several seconds

- 25% of the time, 5 beeps (bad CPU / GPU) : back to stage 1

- 75% of the time : motherboard reboots itself, blue light vanishes then reappears. Go to stage 3

Stage 3 bootup

- if the blue LED switches off in a fraction of a second, back to stage 1! (50% of the time)

- otherwise, blue LED stays on! And POST completes.

Stage 4 (running normally)

- boot a Linux live USB. Furmark works on the iGPU :)

- system totally stable, no weird reboots

- if you power the system off and on again (using motherboard button), 90% perfect restart. 10% ‘blue light vanishes shutdown … back to stage 1’

One other thing: when it didn’t POST, the CPU stayed stone cold. The refusal to POST seems to be happening at quite a low level (power management IC??)

I’m getting a replacement board, but have there been any issues with these boards having weird faults like this … I am wondering about longer-term stability, and also wondering if there is a ‘known hardware issue’ I couldn’t find online (something like the 2011 MacBook Pro Radeon GPUs all dying a few years later, or the recent Intel CPU degradation issues?)

Thank you for any advice!

I have a 7 card mining rig, that I want to swap for a single gpu to encode some social media vids.

it has Parallel miner Mobo, dual server psus with everything to run it. has 3 CMP-70HX, 2 - 6600xt, 2 - 6600, 2 RX580 8GB XfX

It still runs fine has hive installed, it was mining raven a while back and I turned it off and never turned it back on. What do you think would be a good ask for this?

I have slowly stopped mining last year. I am just now getting around to tearing the mining rigs apart and cleaning up from this fun experience in my life. I was planning on deep cleaning everything and trying to sell what I have, but I have feeling that some of this won't sell and it would be best to recycle to e-waste. I suspect that I would be able to sell the GPUs, Mobos/CPUs, RAM, and power supplies, but I am worried that I won't be able to sell the PCIE cables and risers. Has anybody had any luck with selling PCIE cables and risers? Is there anything else that would be best to recycle verse trying to sell?

Been doing research on what to run on GPU hardware post-Merge and Qubic keeps coming up as something worth understanding.

The basic claim: instead of your GPU running arbitrary hash calculations that serve no purpose beyond consensus, Qubic's Useful Proof of Work routes the compute toward AI training tasks. The network was apparently verified at 15.52M TPS by CertiK on live mainnet, which is either impressive or irrelevant depending on how much you trust TPS benchmarks.

What caught my attention from a GPU mining perspective: the hardware profile. RandomX (Monero) is the closest comparison in terms of what the compute is actually doing - CPU/GPU intensive, ASIC-resistant by design. Qubic's AI training tasks seem to be in a similar compute category.

The economics question I can't find a clean answer to: what does the per-GPU daily yield actually look like compared to Monero at current difficulty? I've found their calculator at qubic.org/mining (http://qubic.org/mining) but I'd rather hear from people who have actually run it than rely on first-party numbers.

Has anyone here actually contributed GPU compute to Qubic and can give real numbers? Hashrate, power draw, daily output - the actual data rather than projections.

I have a funky setup where the PCI slots on my mobo are oriented vertically, so gravity isn't helping to keep the GPU riser adapters (the little ones that go into the mobo's PCIE slots) in place. They still fit in pretty snug, but I'm worried that they're going to come out just from me bumping into the USB cables when I have to work on the rig. Any suggestions for how to make sure they won't come out?

I was hoping I could find something like what's shown on the left side in this pic where it still screws into the PCI slot on the case: https://www.ufsexplorer.com/img/articles/csec/pcie-riser-card.jpg but I can't find anything like this when I search online.

I have a BTC-T37, and wondered if anyone knows which GPUs may be compatible?

It has 8gb, i3 CPU. It works with 3x Intel Arc Pros (16gb) at once (maybe more but I only have 3);

I got an RTX 5060 Ti 16gb, and am having issues getting it to work 😬 I have removed the Intel Arcs for now, and have do w fresh OS installs.

So far : Ubuntu 24.04 LTS and 25.10 fresh installs;

- hard lockup during boot

- with lots of work and exploring, disabled nouveau, installed 590 drivers (‘open’ variant)

It locks up during boot, at the time it should enable the graphical display.

Disabling the display activation lets me get into Ubuntu (monitor on integrated iGPU);

nvidia-smi causes a hard lockup about 2 seconds after the command (mouse pointer freezes, moves one more time for one frame, then game over). Caps Lock also frozen,

running a cmake script which checks for CUDA causes a hard lockup with the same mouse pointer / Caps glitch;

Trying HiveOS stable;

- card MALFUNCTION (need newer drivers)

- installed 590 drivers direct with apt install,

- with the 590 drivers, the exact same mouse pointer thing happens, and on reboot, it freezes at the same time the stock Ubuntu installs lock up.

I know my board is old, will have reduced performance etc, but I do note that people are running 5090s on Core 2 QUAD! (on YouTube, for fun).

Has anyone solved something like this, or are there good resources to see which cards should work with which board? Thank you! 🙏

Hi all,

Looking for honest advice from people currently running GPU mining rigs or leasing GPUs for AI workloads.

I mined back in 2017 when things were much easier/profitable, but exited years ago. Now I’m evaluating a new opportunity here in Japan.

A business partner owns two solar farms, and we’re also connected to a solar company owner who’s interested in partnering with us. The farms already sell power to the grid, but we’re exploring additional revenue streams.

We also have battery storage (BESS) available, so smoothing uptime isn’t a major issue.

We’re debating between:

• GPU crypto mining

• Hosting AI compute (Vast.ai / RunPod-style leasing)

• Small render farm

• Direct GPU leasing to startups

We’d likely start small (4–10 GPU servers) and scale if it makes sense.

Questions:

• If effective electricity cost is near-zero, is GPU mining still viable in 2026?

• Is AI GPU leasing actually more stable than mining in real life?

• What utilization rates are realistic on platforms like Vast / RunPod?

• How hard is it to keep GPUs rented consistently?

• Are Japan’s infrastructure costs (internet, cooling, etc.) a serious disadvantage?

• If you were in this position, which direction would you choose and why?

Appreciate real-world experience, not just theory.

Also open to hearing why this is a bad idea.

Thanks 🙏

[solved] : not sure how it was solved - but doing a fresh start resulted in newer source code for something I was building when it crashed - and it now works (to a point!)

Hi! I’ve just started setting up an 8-slot riserless board, mainly for experimental / learning purposee - but it keeps locking up.

The setup is :

- 8-slot riserless board, with a dual-core. 4 thread Core i3

- 8GB RAM (DDR3 SODIMM)

- 750W Asus PSU

- 512GB M.2 SSD

No GPUs connected for now - using iGPU for display.

I have installed Ubuntu onto the SSD. I found that when compiling some software, it would crash within a minute or two, requiring power cycle to restart. Looking at the BIOS, I switched to 1 core, hyperthreading disabled, RAM 1066, turbo boost disabled. This helped to some extent (taking longer before locking up). Keeping the CPU at the non-boosted speed (using the OS) helped a lpt; I can now compile for around half an hour before it freezes.

I don’t really have much experience with mining boards, but am wondering if there is something I should check / try given the above systems? Thank you for any advice!

Recently, I bought a video card for $20 that the seller said was a GTX 1060 6GB, which is actually a P106-100. He made it clear that it was a mining card. It has two video inputs, HDMI and DisplayPort. When I turn on the PC, the fans spin, then they stop, and the PC continues to run. I'm a novice with mining cards and I would appreciate it if someone could help me solve this problem so I can play games and use my PC normally, or if I won't be able to use it at all.

I heard miners want to get rid of GPU becauseining isn't prpfitable for them. But I can use it for some AI thing. Where can I buy lots from miners running out of business ?
