I've got... an RX 570 to give away.
Edit: Looks like we've got a winner!
It's an MSI 8GB 'Gaming X' model. Very nice, very high-end. Factory OCed, pretty sure.
Well, in the dual-GPU rigs that I run, it runs TOO HOT. Plus, the last couple of rigs that I've had it running in (in a pair), the rig was SHUTTING DOWN. Two different rigs, one with a recent (less than a year old) EVGA G1+ 650W 80Plus Gold PSU, and one with an EVGA Bronze (well-used) 600W PSU, that was upgraded to a fresh new Antec VP650 650W PSU, and still shut down the PC.
Not entirely sure what the issue was/is, other than I think that the card was hitting 95C+, and triggering some sort of emergency shutdown of the PC.
It might just need a re-pasting, might need fans oiled, might be a tiny bit bent (no back-plate).
It's yours, completely and totally AS-IS, FOR PARTS ONLY, for the cost of shipping. Which, in CONUS, is a $15 flat-rate med. Priority USPS box.
I'll miss it a lot, and I hope that possibly, one of Folders or BOINC'ers ("bonkers"? LOL) might be able to utilize it.
I mean, maybe I could use it in Dec., for the F@H race, if I put it and only it into a PC, and ran it singly. If no-one steps up and asks for it by the start of Dec., that's probably what I'll do with it.
And for the F@H crowd, it's not nearly quite as power-efficient as the newer NV Turing and Turing "Lite" cards, but it still only takes a single 8-pin PSU connector, I believe.
Was trying to sell it, originally, and I'll update my FS thread accordingly after I post this, but I've finally sort-of diagnosed it that the card seems to be the problem, and not the PSUs or Windows 10 installations on several different PCs.
Edit: PS. The card itself, even thought I said "for parts only", is not actually DEAD in any way, that I can see, it just... has tendency to get too warm, under any sort of load, and even a light load, BOOM, it seems to be at 90C+. So maybe something got warped, and it's not making good contact with the (substantial) heatsink.
Edit: The card I bought as a replacement, a REFURB RX 580 4GB Sapphire Nitro+ version (6+8 pin), is showing in HWMonitor that it's using 135W (way more than the 80-90W, maybe 110W that the MSI 8GB RX 570 'Gaming X' took), and yet, the temps are at 72C and 1700RPM fan-speed. The 'Gaming X', the temps would be pushing 90C, and the fan RPMs would be at 3300RPM, with less wattage being used. Go figure. So I think something either is warped, or needs re-pasting, in the cooler.
It's a fixer-upper opportunity.(*) (*Assuming that I haven't popped a cap or fried a VRM on it, which is also possible.)
Edit: I took a good look at it, after putting it back into one of my "mining GPU shell" PCs, for mining (new algo, paying out bigly, relative to what's currently paying out), and I gave it a good look. It's warped. Kind of twisted, a little bent down to the right, when installed. No wonder it's not making good contact. I'm not really sure how to straighten it out, without breaking traces on the PCB.
Is it possible to get after-market back-plates? Could one make their own, if done properly, and get updated GPU mounting hardware that would mount square? Certainly would help to have a machine shop or CNC machine, probably, and access to a variety of metal screws and bolts. Maybe someone's up to it.
I currently have it mining at -20% power reduction, which allows it to mine 5-10 shares, before temps hit over 85C, and it has to have a cool-down phase in the mining software. Maybe that will keep it from over-heating and the PC shutting off. Better than nothing, I guess, making $0.45/day.
