Check what power you have across the PCIE slots and that the PCIE slots are x16 and not x8. I've just removed around 15 Dell R610s from our DC and had thoughts of frankenstiening a few of these for the garage at home but they are useless.
Why do you need x16 slots?The mining limiter on 3060 v1 cards will kick in though if not in at least an x8 slot. Surprisingly few boards around with 2 let alone 3-4 of these!
I'm guessing this is in the context of splitters though, if you're going to split an x16 slot it needs to have enough pcie lanes wired up to split in the first instance.
Dedicated mining boards will normally have loads of x1 slots which will work fine with risers.
It's been a while since I looked inside any Dell servers of that vintage, from memory they have limited slots unless specific daughter boards were spec'd initially?

I have an issue with my one watercooled 3090 founders (https://www.ekwb.com/shop/ek-quantum-vector-fe-rtx-3090-d-rgb-silver-special-edition), where I've bought what was supposed to be the best waterblock (EKWB Ltd Edition) and the temperatures I am seeing are just not very good. In fact my aircooled ASBO machine has cooler 3090s with cooler GPU core and VRAM. At that point you need to decide if the water in my waterloop is getting cool (IE isn't capable of shifting out the heat produced) or if the waterblock for some reason isn't transferring the heat. I have a 2080ti in that same pc and waterloop and I know that the temps it is seeing are exactly as expected, so I am confident that my waterloop has cool water in it, so that points to the way overly expensive waterblock not doing its job. I need to tear the waterloop down after draining and find if there is anyway that the waterblock isn't sitting flush. Maybe a thermal pad is in the wrong place and forcing the waterblock up 0.5mm and the contact across important components isn't ideal. Plus on my aircooled 3090s you can add an alloy heat sink to the backplate where the rear VRAM is and work to actively cool that but on the waterblock it isn't really active cooled so the VRAM of the watercooled 3090 is at 100c (erk) when producing 126mhs. ANyway, EKWB have a properly active backplate for this same waterblock that should be available for posting out on the 30th of September. (https://www.ekwb.com/shop/ek-quantum-vector-fe-rtx-3090-d-rgb-active-backplate-silver-se). When this arrives I will take this loop to pieces and inspect the setup to make sure that I am getting the best contact possible, also add in this active backplate, flush the loop etc. This particular waterblock is not in line with the usual cost of a waterblock but it sits in my gaming pc, so I wanted the best that was available and didn't use much commercial thinking when buying. Total cost of the components is €500 just for the block. No sense at all.
Do you know the active backplate needs a spare slot above the card, I don't have that spare space in my machine

With the increasing energy costs and the crypto slump, how are the mining operations currently holding up?
At what price does it no longer become profitable for you to mine ETH at home?
My fag packet maths say I'm mining about 2.5x my energy cost right now.At what price does it no longer become profitable for you to mine ETH at home?
Equipment costs are sunk and I'm mining to hold so will keep going. The question is will there be another big crypto boom, or is this the beginning of the end, I have no idea, but I'm betting on a boom and can afford to be wrong.
Also the rig doubles as effectively free heating for the garden office this time of year, so man maths could adjust the power cost to zero!
I certainly wouldn't recommend getting into it now though, equipment costs haven't got any lower so return on investment must look dreadful.
As previous poster says, there’s no way I’d get into it now. GPUs even harder to get (especially now nvidia released the LHR ones).
However my rigs just keep on chugging away. I’m running about 4kwh so about £17 a day, but I’m getting around £50 a day in mining fees (fluctuates a lot depending on the ETH value).
Plus the rigs themselves seem to be going up and up in value. Around £17 per m/hs seems to be the going rate. That values mine at £17k. I paid around £9k

Agree with both of the above, mine is still ticking away albeit at about half the $ profitability compared to much of last year.
It would take a further plunge in ETH/BTC and/or an another spike in electricity costs to make it unprofitable, but that's only if you measure against fiat. If you consider you're still getting the same ETH/BTC as before and expect the $ value to rise again, then there's really no reason to stop.

Interesting that the environmental cost isn't even mentioned, much less considered 
It heats my house. My house has electric heating. More mining, less compressor run time. At this time of year there isn't much in the efficiency of the two methods.In the summer, yes, maybe
Right guys just thought I’d update. I’ve sold all of my rigs/GPUs this weekend. I got much less than I could have 6 months ago but I still made profit from what I bought them for (or cobbled them together more like).
I worked out with the electric costs (27p per kWH) and the price of ETH (£2,250) that they were actually costing me money to run (with the aircon etc). I’m approximately at 5kW and that’s about £1.35 an hour (£226.80 a week) and my 1,000mhs currently gets me about a tenth every 7 days (£225).
“It was good while it lasted” I guess is the summary of the 2 years I’ve had them.
Anyone else selling up? Or at least turned them off for now?

For me it’s not the ETH price necessarily but purely the electric price. Mine have doubled in 6 months so where I was making £100 a week profit, I’m now making nothing.
Yes I could hold onto the ETH in the hope it increases but I never did that, as soon as I got my tenth I used to cash in. This way I averaged out the price. I know others who hold onto their mining earnings but for me I guess I didn’t actually believe in crypto that much so took out my money as soon as I could.

Could you not take it to work, and plug it in at work ?Yes I could hold onto the ETH in the hope it increases but I never did that, as soon as I got my tenth I used to cash in.
