    I'm anticipating approximately 130kWh usage by my systems for the duration of the event. I have two-tiered billing: $0.09/kWh up to 1350kWh/mo and $0.14/kWh for consumption over that threshold. I anticipate an average cost of $0.11/kWh for the billing period, so $14.30. The building my hardware is in is heated by a mid-efficiency LPG/propane furnace, so the heat produced by folding won't offset electric resistive heating costs, but it turns out that my propane is super expensive. If propane has 7kWh per litre and cost of $1.18 per litre, then it costs $0.168 per kWh. Worse, my furnace will have 85% efficiency at best, so it would be fair to say that 1kWh of heating would cost me approximately $0.20, or $26.00 for 130kWh of heating. So, it would appear this folding event has potentially saved me $11.70 in energy costs! I wish I had a larger electrical service to the property in order to replace the propane furnace with a lot of folding rigs (or a heat pump)

    Well this is interesting. The OS stats screen shows 6 AMD GPUs under Mac OS now. Considering there has been no Mac OS GPU support thus far, I wonder if there's a new development, or if this is an anomaly.

    Nothing about these should negatively affect folding performance over something like a GTX 1050 Ti. They appear to utilize all 16 lanes and are PCIe 3.0, but PCIe bandwidth isn't a huge factor in folding AFAIK, just as it isn't in mining. I don't know if these can be fully bus powered as a 1050/Ti can. I suspect they can, but have the 6-pin plug for mining rigs that only provide an x1 electrical interface to the cards. EDIT: I can't figure out definitively if the Zotac cards have any of the bus crippling that seems to be present with the no-name and possibly Gigabyte variants. PCIe 3 x4 or x8 shouldn't drop PPD too bad, but dropping down to less than PCIe 1 x16 or PCIe 2 x8 might pose a problem.

    It actually looks like there were a few. The reference design was a 12" card length, but techpowerup has a handy table that shows variations on the card design: https://www.techpowerup.com/gpu-specs/radeon-r9-290x.c2460 MSI and ASUS both have a number of cards using an open air cooler in a shorter length. Here's an MSI: https://www.ebay.com/itm/MSI-Graphics-Card-R9-290X-GAMING-4G-Video-Card/254116992562?hash=item3b2a8d9632:g:--AAAOSwaAlcX3IE

    In that budget, an example of an RX 580 with an open air style cooler would probably be the best bet. The RX 580 has a TDP of 185w, compared to 150w for the 480. If you really want a furnace of a gpu with an open air cooler, some versions of the R9 290x were available configured as such. The 290x has a TDP of 290w. Here's a used example with an open air cooler on eBay: https://www.ebay.com/itm/Sapphire-R9-290X-4GB-GDDR5-Dual-DVI-D-HDMI-DP-TRI-X-OC-Version-PCI-Express-GPU/202956296143?hash=item2f41234fcf:g:UDQAAOSwFnleiSDN

    As for used <75W cards, the GTX 1050 Ti would be the best option.

    I mean.. at least send the message by fax, carrier pigeon, voicemail, telegram, smoke signal, etc!

    Looking at prior posts in this thread, the OP has tried a different power supply with the same result, DDUd, tried the card in two other systems (it worked fine). Given that the card behaves in other systems, I'd be most concerned with BIOS/Firmware and potentially the new motherboard. Is the behaviour the same in any of the x16 slots? If you're concerned about flashing BIOS/Firmware right now, you could just check the version against what is available from MSI. If it's older than 7C02v35, aka 3.5, then it's not current. That version addresses some PCIe compatibility issues according to the changelog.

    Is this the same GTX 960 you were having problems with driver installation and 3D acceleration after switching out motherboard/RAM/CPU? I'd be quite suspicious of the power supply given that you're still having crashing issues when you're getting into 3D games. The extra coil whine under lower load could be due to the 12v power rails getting pulled lower than with your old configuration and the GPU's VRMs working harder to compensate. When you load up the card harder and you get blank screen and other issues, it could be the 12v rail dropping further below spec and causing the card (and maybe other hardware to reset)

    Do you have your CPU slot configured to client-type=advanced? If not, give that a try to get some much bigger base points, potentially bigger final points (if your CPU can chew through it fast enough.) It seems a little much for my i7-3770, but an 8700K? probably good.

    I can't get over how cool I've got my Vega Frontier Edition running. Granted, the fan is incredibly loud, but still. 200+ watts and staying under 60C on a stock cooler is pretty good in my book.

    The ridiculous thing is that wire sizes in North America go to a different unit above 0000 gauge -- kcmils, which despite sounding kind of metric is thousands of circular mils-- and mils are thousandths of an inch in US parlance. In Canada if we have to use thousandths of an inch, we call them "thous" at least. Metric is used universally in official weights and measures here, but colloquially it's a mixed bag. In trades (such as construction) it's rarely used. Oh in reference to the receptacles, it's 12 AWG copper wire to the 20A as per electrical code. If it were a really long run, I might have used 10 AWG, but the plug is less than 20cm from my workshop circuit breaker panel.

    Woohoo!

    That's why I put that 6-20 in, just for itty bitty welders though!

    I'll bet there's a few of you out there wishing you had one of these winky faces right now
