  • First Build + Workstation/server card benchmark

    Well, I've done it. I've seen a few posts running around about it, but no real info to date. So - in the name of science, of course - I picked up a few FirePro S10000 12 GB cards and I've started mining with one of them. Why only one? Because I'm still waiting for FedEx to bring me my beefier PSU that can handle all of them. For those of you who have wondered, here's what I'm running and what I've found so far:
    ASUS M5A97, AMD chipset with FX-4350 CPU.
    16GB RAM
    120 GB SSD
    GT 710 for a simple energy-efficient VGA output (no video output direct from the motherboard)
    Windows 10 Professional, but I might get set up on Ubuntu. Then again, my already limited Linux skills are pretty rusty.
    Currently running Claymore's Dual miner, since I'll be running both AMD and NVidia cards.
    The motherboard recognizes the two Tahiti cores of each S10000 as individual GPU's. That's probably normal, but this is my first build, so how would I know? I'm just hoping my CPU can handle enough PCIe lanes, etc. to manage all five S10000's that I have awaiting installation and tuning, in addition to the five 1050 TI's that are also on the way. Not to mention, I've yet to test all of my risers, splitters, etc.
    For now, I just have a couple 92mm fans that I salvaged from the case that my brother-in-law had for the motherboard directed right at the S10000 that I've installed... right on the itty-bitty motherboard while I await the rest of my components to finish my build. This thing is monstrous, both in size and power.

    So, The max TDP of the S10000 is rated at 375w, though I'm finding mixed information on whether that's per core, or for the whole thing. I really, REALLY hope it's the whole thing. I'm currently running an EVGA 850BQ PSU that I got to fire up and check out the motherboard, since the motherboard was a random Christmas gift/hand-me-down from my brother-in-law. That said, I haven't really been able to push the card that far. It already set off the over-wattage protection on the PSU a couple times during benchmarking, among a couple of random display issues. I'm not sure if my motherboard is trying to switch the display output from the 710 to the S10000 as the latter starts pulling some power, or what. Still troubleshooting that. As for hashing... HOLY COW. Each core can pull about 20 MH/s, at least until it crashes the PSU. So far, I've managed one stable benchmark at ~50% intensity, and each core averages 11.4 MH/s at that intensity. I know, I know. The jump from 50% to 100% intensity isn't necessarily linear in terms of a jump from 22 MH/s to ~40 MH/s. However, AwesomeMiner approximates its configuration as "Dual 20.4 MH/s," so I'll have to see how that pans out given adequate power to the cards, and some fine tuning in AfterBurner.

    Now to the rest of the build:
    All of the above, quite obviously
    5x FirePro S10000
    5x GTX 1050 TI
    Dual PSU's: The aforementioned 850BQ for the Motherboard, 3 1050 TI's, and the fans. Plus a 2350w (supposedly) monstrosity I came across on Wish for dirt cheap (likewise with the 1050 TI's. I hope to God they're the real deal)
    10x 40mm fans in a custom open air frame I'll be constructing myself, and I might find a use yet for the 92mm fans I salvaged from the old tower case. I like the idea of each GPU having a fan to itself, but I'm expecting some diminishing returns on CFM airflow to cooling efficiency.
    All in, given some tuning, etc. I should be looking at about 250 MH/s and around 2000w power draw. It'll take some trial and error to optimize the power draw to hashing power ratio, but I think I'm headed in the right direction so far.

    And in case anyone was wondering how I ever afforded five S10000's, they're not $3500 anymore. You can find 'em on eBay for about $300. Far less expensive than the Vega and 1080 series cards in terms of upfront cost, but at nearly double the power draw. Theoretically, though, they should offer an extra 10ish MH/s over their gaming-oriented counterparts. Whether that's worth it, I've yet to see. Anyway, thanks for reading, and I'll keep you posted on build progress and final benchmarks as I finish up.

    Cheers,
