You need a CPU in your mining rig anyway, might as well have it do some work. Also, a GTX 1060 or RX 580 were $500 GPUs at the worst of this, so the price / perf of these iGPUs actually isn't bad.

Which is absurd enough, but $500+ is really more like 1070 territory. Paul MaudDib fucked around with this message at 21:53 on Feb 13, 2018 |

A friend of mine is elbow deep in the poop, and because of GPU prices going up he's switched to buying quad-socket AMD Opteron 6380 servers. He's got 10 of them so far at I believe an average price a bit under $800 each. You mine the coins like Monero or Verium that aren't easy to GPU mine.

People do it, especially given how bare the GPU market is at the moment, but it's still a stupid idea. Take a 1920X, you get half the Cryptonight hashrate of a Vega 56 for the same power, at roughly the same price (current market price). If you can find some older hardware with tons of L3$ very cheaply it's not a terrible idea, any more than it's a terrible idea to pick up GCN 1.0 hardware if you can find that cheaply. Cheap hardware is cheap hardware. But most people are more constrained by their wiring than anything, and half the hashrate at the same power = half the power efficiency. If you are really going elbow-deep in the poop you need to think about efficiency because you can only run so much hardware on your standard 15A-peak/12A-continuous household circuit, and that's going to become your bottleneck. 120V really cannot carry all that much power. Unless you have spare 240V circuits, of course. Those can carry a lot more power, but still, only a couple of rigs per circuit. Or if you go ahead and rent out a commercial space with commercial electricity - which is probably a smart idea if you don't want heatstroke. The math for scaling out your mining op beyond a handful of rigs favors running Celerons and putting the money into an extra GPU or two instead of a super-powerful processor, both in a profit-per-dollar and a profit-per-watt sense. I really doubt you would see many professional mining ops with Ryzens, Threadrippers, or Opterons. Paul MaudDib fucked around with this message at 23:38 on Feb 13, 2018 |

Some of the GPUs had reliability issues after a while, but they were used 24/7 for crypto then 24/7 for research so really how long can they last? I'd say around 80% of them are still fully functional and they've been in use 24/7 since the 560 Ti came out. None are underclocked or anything. They run at stock settings. I can't imagine there are many/any like that in the US anymore. Khorne fucked around with this message at 01:07 on Feb 14, 2018 |

https://www.youtube.com/watch?v=7o1ITMw-O2o Speaking of GN and APUs, I wasn't originally going to link this, but three things: 1) APUs appear to be a monolithic die, as opposed to an MCM. 2) AMD does what Intel doesn't, and have an island on the backside of their heatspreader. I'm hoping that because of the island, there's less thermal paste that heat has to get to to get to the heat spreader, and is basically what I've been saying Intel should do for nigh-on a loving decade now. 3) That is one thick-rear end heatspreader. Seriously, almost the entire thickness of the heatspreader is solid, it's just a small island and a slightly-taller parapet. One wonders if they couldn't have gotten away with thinner if they had not insisted on allowing the re-use of AM3 cooler mounting hardware.

(0) Oh Steve, you so sassy. (1) Ryzen is a monolithic die too, that's not actually surprising. (2) The island is a good idea. I've actually gone farther and said that I think they should flip the interposer upside down, connect the MCM dies to the backside and draw the heat down. Maybe even with a peltier (since there will not be that much heat overall). That way they could have an active interposer on the top (now bottom). I mean, the problem is the dies stacked on top that aren't letting heat through, right? Let's turn that frown upside down.

I talked to the guy about it, and he's got 2 30A 240V circuits going to where the rack is, and one power rail of the rack plugged into each circuit. It looks like those Opteron 6380s hash at about the same rate as an R7-1700 or 1700X, so $200 per socket all-in including CPUs, power supplies, RAM, cases, etc sounds like a decent deal. It also looks like cryptocurrency mining is best case workload for CMT. Now, he's still hosed if prices go any lower, but buying used hardware seems like a saner way to do this.

I still think he could probably squeeze a bit more out of his budget/power with GPU mining (even at current eBay prices) but if he can push a couple hundred H/s per socket that's doing pretty well for CPU mining on cost/power.

The regular CPUs (R# 1XXX), probably not much. I believe all SKUs are already soldered where the Intel units all have TIM. Delidded APU results are still coming through.

But they still haven't posted what that translates to in terms of overclock or benchmark yet. I can see why AMD would just TIM the caps if some other factor is the bottleneck.

I mean in the sense of "there's not much more room to overclock beyond what was already possible with TIM" GN's overclock shows them already pushing 3.8GHz @ 1.4 volts, after all.

Buy a Ryzen APU with your AM4 board, but have no way to update the board's BIOS so it actually works? Don't worry, AMD will mail you a new in box A6-9500. https://arstechnica.com/gadgets/2018/02/amd-sending-out-free-processors-to-solve-firmware-flashing-catch-22/ AMD wants you to send it back after... but just the chip. You can keep the HSF and box(?). Thats one way to write off the deadstock i guess.

Some of them won't take random stuff that's not an obvious food container or marked with a plastic recycling number. I think stuff they can't handle just goes into the trash. An e-waste program will usually take random computer stuff and sort it for reselling or scrapping or whatever.

Gigabyte has it on some boards as well. edit: looks like MSI and Asrock have it on some boards too. Nobody really implements it consistently across all their boards, though, which is annoying. It doesn't seem like it would be that hard a feature to implement and it's very useful. Maybe it is a patent situation then... Paul MaudDib fucked around with this message at 04:42 on Feb 17, 2018 |

If you have enough of them you can bring them to a metal recycler and get money for them. They're paying €0,85 per kg of aluminium and €4,30 per kg of copper locally. Probably not worth the gas money for aluminium but if you had a dozen of those old 700g solid copper Zalmans it could be interesting. Personally i'd just throw them in the metal recycling bin we have at the recycling center.

Over here in Belgium, if you bring an overabundance of copper to the recycler, they will want to have receipts of where you got that poo poo. So if you bring a lot of heatsinks to them, they might get antsy whether you stole that poo poo or not.
