Typical crypto miner setup. I had two 6GPU setups with 1200W PSUs and 6 PCIE slots with PCI extender cables. Its value dropped harder than a cyber truck's after a few months.

The worst thing is dust. They would accumulate so much every week I had to blow the dust off with an air compressor.

Electricity cost was around $4 a day (24 x $0.20~). If online GPU renting is more expensive, maybe the initial cost could be justifiable.

Except not doing the sketchy x1 pcie lanes. That’s the part that makes nice LLM setups hard

Can you tell me what's sketchy about it? I have not had an issue with any one of the 12 extenders and bandwidth held well without any issues. Please explain if possible if LLM requires a different type of extender.

Eh perhaps poor choice of words.

It works fine for crypto but LLM performance is far more sensitive to bandwidth. You lose a ton of performance if you’ve got PCIe in the loop, never mind one lane pcie. That’s why nvlink is (was) a thing - trying to cut that out entirely.

Got it. I was planning to switch my miners to LLM farm. I will test and see how much of a difference it will make. Thanks.
