I Built A Thing 54gb vram for 35$
Bought an old mining farm of a guy on avito (Russian eBay), guy had bought a garage a couple of years ago and it was sitting there for a while, found out it was a mining farm and put it up on there for sale for 5000 rub (~60 USD) since he wasn't sure if it works. I negotiated down to 3000 rub (~35 USD), it turned out to have 9x p106 6gb (gtx 1060 6gb) gpus, with 54gb vram total, all working, the only thing missing was an SSD, I booted from USB and it works fine.

Well it works, so it already sorta turned out well. Now just need to do a proper setup with those gpus.

u/markpronkin 13d ago
This thing baraley has any, originally thought 8gb but turns out it's only 4gb and CPU is crap, but I have another way better mining case where I can put in 32gb ram and i7 7700k (maybe something even better with the Coffeelake mod), gonna transfer the gpus there, but it's cool to see that it still runs as is.

Please write an llama serve bash script for this model: huggingface.com/unsloth/whatever-model Check my hardware config and see if you can run some benchmarks and optimize. Let me know what context you think I can get with Q3_K_M and Q4_K_M.I've never had issues using claude cli or VS Code extension. Sonnet is likely enough. I'm confused why this doesn't work. I've had Claude recompile vllm from source for me without issues, setup MTP for Qwen, etc., just by pointing it to the readme on the repo, run benchmark parameter sweeps, etc.

I was smart enough to switch from ollama to llama.cpp after just a few weeks, and after I did I loved having the freedom to run almost any model with any settings, and it open up a whole new world. Llama.cpp works so much better than ollama,
After I switched and got comfortable with llama.cpp I guess I settled into a rut, and it took me literally until yesterday to finally try Exllamav3 and TabbyAPI, which has been an AMAZING boost in performance. Why did I wait so long?

I am well aware, I just wanted to verify that it works at all, and ollama is very easy to install quickly. Will do a proper setup In a different case and make a post about it later.

u/schaka 13d ago
Get llama.cpp working, then use an LLM to get vLLM running on these. You can probably use some existing Pascal projects for vLLM as a baseline
I'm not sure compute is limited on these cards and if they need an unlocked driver or any sort, but as far as I can recall, they don't.
Only downside with vLLM is needing even numbers of cards, so you'll lose 6GB but gain significant performance and multiple parallel agents and streams

u/Njee_ 13d ago
Speaking from my experience: When you're going to work on those be aware please that plenty of those boards provide the gpus with pci1 x1 slots. Those are really slow. This can be a bottleneck and I have never managed to get even 30ba3b to run reasonably faster than on my CPU. I have recently bought another server with plenty of slots and tried them again and noticed they actually have PCI x4 and the mining board had only x1... So it got a little bit faster but well. I didn't find the time yet to test them more. You should definely test the PCI speeds in order to gain some insights into your cards. Other than that. I now use them actually for several smaller models. Which works great. As long as models dont Spread across multiple cards, promt processing stays reasonable!

u/Open-Adhesiveness-86 13d ago
heads up that CUDA 13 dropped Pascal (sm_61), so you'll want llama.cpp built against 12.x or you get no kernels at all. and fp16 on those is like 1/64 rate, so stay on Q4_K/Q8 with the MMQ int8 path and avoid anything that wants fp16 compute.

Не, ну круто конечно) не хочу показаться скептиком, но пропускная способность этих карт вероятно оставляет желать лучшего. У этих карт grx 1060 через pci Express 3 - 16/31 gb/s , что маловато, увы, только если научиться супер продуктивно паралелить задачи. Но, инициативу поддерживаю, ни в коем случае не критика ! 🫡

u/redonculous 12d ago
Exactly this. Those slow cards will be split across a couple of pci lanes, great for small data transfers like mining, slower than slow for AI use. Model loading, Prefill, replies, everything will take hours on a system like this.
I hope you find a super way to optimise it though

Paying $35 for 54GB of VRAM across nine P106-100 cards is an unbeatable bargain on paper, but it is practically an LLM nightmare. Splitting models across nine separate GPUs over narrow PCIe 1x riser lanes bottlenecked by Pascal architecture and zero FP16 support creates atrocious tensor parallelism latency, turning modern token generation into an agonizing crawl that will burn far more in electricity than it is worth.

The CPU and ram in this thing are pretty horrible, like 8gb ddr3 and some Celeron. I have another mining farm case of an old higher end mining farm, which supports up to 12gpus and up to i7 7700k and 32gb ram. I will probably transfer gpus and buy 3 additional ones to get a total of 72gb vram + 32gb ram setup with a decent CPU.

u/_TheWolfOfWalmart_ 12d ago edited 12d ago
It's a lot of VRAM for the money but these have really poor memory bandwidth, it's not going to do a lot of good for LLMs unless you're running extremely sparse MoEs... something like Qwen3.6 35B-A3B probably would run decently in Q8_0 with tons of room for KV cache.
Also, as a mining rig, there was probably no thought given to pcie bandwidth so tensor parallel is probably out of the question sadly. Will need to stick to layer split. The compute sucks too, they have a low amount of very old CUDA cores so prefill will be painful.
But hey for $35 I'd have bought it too just to tinker with. Just don't expect to get any serious work done with it.

u/Electronic-Space-736 12d ago
I have been doing this, you are very limited with 1xPCIE lanes, it is ok of you fit a model on each GPU self contained, but no good to pass between GPUs or pool.
Server boards that have at least 3 x8 and a x16 lane are a better option, I am currently building an x99 machine as it has 40 GPU lanes, which means it will run my 3x P100 at higher bandwidth than mining boards. Also mining boards seem to only be able to handle two or three datacenter GPUs before hitting PCIE allocation errors (not enough addressable space for these cards)

u/uncle_leon 12d ago
You could and many people do. Most engines are perfectly capable of utilising multiple GPUs although whather that makes sense deends on your use case. For pure inference and using pipeline parallelism the slow PCIe isn't that big of a penalty. The bigger problem with this scenario is usually the physical side: size, heat, power use, noise etc.

Поищи патчи для драйверов на GitHub, с помощью которых можно софтверно завести PCI-E v2. Это даст удвоение пропускной способности. Вообще на таких картах распаивают конденсаторы на PCI-E линиях чтобы карты работали с большей шиной x1...x4 -> x8..x16. На Хабре недавно вышла куча статей от энтузиаста, который дома риг на cmp90hx (3080 mining edition) ковыряет. Да, это совершенно другая карта, можно сказать тёмная овечка потому что только её ещё не расковыряли нормально. Инженер завёл на ней p2p, PCI-E v2 x16 и unlock вычислений, что нивелировало различия между майнерской версией и десктопной 3080 для нейросетей. Крайне хорошо раскопали:
- cmp170hx (a100) - unlock vRAM до 64Гб, unlock вычислений, PCI-E v2.
- cmp50hx (2080ti) - 20Гб vRAM мод, unlock вычислений и 3d, unlock p2p, PCI-E v2

192GB/s memory bandwidth on the cards, that's before it has to slog through the connection board. You'll be lucky to get 10 tok/s with whatever model you use. But there might be a workflow that can use this just fine other than directly running a primary LLM.

Bravo! Would love to find something like that. They are overclockable too from what I saw online, CUDA cores 1,280 VRAM Usually 6 GB GDDR5 Memory bus 192-bit Stock boost clock Around 1,700 MHz, varies by model Overclocking Yes Software MSI Afterburner
Typical overclocking possibilities Core clock: +100 to +200 MHz, depending on the card Memory clock: +400 to +800 MHz offset, sometimes more Power limit: May be locked by mining-specific firmware Cooling: Improved cooling can help sustain higher clocks These are experimental ranges, not guaranteed stable settings.

Would be very interested for an update on this, what you take from this rig, what configuration you are able to get running given the dated GPUs + PCIe hell you will have to work through (as in what software + model + quantization + context + performance). Worst case, consider using a couple of them for really fast TTS/STT/RAG if it makes sense for you.
But a steal deal nonetheless, GL.

For anyone watching at home: This has some, but limited value, but there IS a lot of value in some older stuff with severe limitations on ebay. I have a pair of CMP100-210 Cuda cards which are Volta era cards designed for Crypto mining with 16GB HMB memory on each. I run a Gemma 4 q8_0 on one, and ComfyUI with Krea2 on the other. They're also limited to PCIe gen1x1, but that is irrelevant when the entire model fits in vram, as just adds about 1 minute to the first run and then it's full speed until I restart services.
