    Post your mining rigs

    I'll start. Shown is the hot aisle for most of my chia farm. Servers showing 12x drive bays are 36 bay servers. I have 3 more 36 bay servers hosted at a real datacenter for the moment. What is shown is in an evaporatively cooled warehouse. Everything that's not in a 36 bay here is a plotter...

    Scalable CPUs to watch

    Probably will start seeing scalable coming on the used market in the next year or so. As you can get 14 core E5-2680v4 CPUs for $150 ea and 18 core E5-2695v4 CPUs as low as $200 each, I think you'll want to see 22 - 24 core scalable CPUs in the $200 range to justify an upgrade. As 28 cores is...

    Recommended cheap used enterprise sas12 SSD for cachecade?

    I've noticed the LSI 9300 series (such as 9361-8i or 9361-16i) are the newest that still supports cachecade. The 2gb ram cards support up to a 2TB cache, unlike 512gb max for 1GB hw raid cards. On 9271 raid cards I just use 4x 400gb Intel DC S3700 drives in raid 10 due to their excellent write...

    EPYC ROME Motherboards???

    Seriously are there any out there you can actually buy? Provantage has a few listed as special order. Newegg has a couple that come with CPUs for $$$$$$ and says no returns, replacements, or refunds. If I want to build an Epyc Rome (or heck, even Threadripper if it has ECC and IPMI) what...

    DIY swamp cooler

    Arizona gets pretty hot. The garage has no cooling (or insulation, sadly), so it's been getting up to 110+ degrees, with sub 10% humidity. Have built a home made swamp cooler to address this, so that the garage will be cool enough to run servers. Have put 6x noctua fans blowing out of the...

    PCIe U.2 to 12g sas adapter 1u?

    Hey everyone. Much appreciate the help in the other thread regarding U.2 to pcie, having the drive attached to the addon board. Have a slightly different scenario here. Have a pretty standard 1u chassis where I do have access to 2.5" / 3.5" bays, as well as molex and sata power. But, no native...

    Draw sata or molex power from pcie slot?

    Not sure which subforum this is best for, so here goes. I'd like to power couple a u.2 nvme ssds in a chassis where this is not possible. The only place you could get power for anything the manufacturer didn't specifically design for, is the pcie bus. The server supports 75w draw for gpus in...

    Custom Water Cooled Rack (Fun with Prototyping)

    As mentioned in another thread, I recently got a monster radiator. It was suggested I make a thread for the project it's related to. So here we are. A bit of a loose prototype kind of project at this point. The general theme is rackmount server cooling efficiency. One major thrust of this is...

    Juniper EX4200-48T + 2x10g + rails + dual psu -- $148

    EX4200-48T JUNIPER 48 PORT 8 PoE GIGABIT L3 MANAGED SWITCH WITH 2x AC POWER | eBay Of all the Juniper EX4200 models, this will be the most power efficient. The 48-poe model uses quite a bit more power (even when not using POE). The larger PSUs use more power as well. So the 48T model with the...

    DIY Air filter boxes / fan enclosures (pics)

    Please forgive the "1.0 prototype" made out of cardboard. Wanted a quick proof of concept -- it's being replaced with the 2.0. Anyway, bringing in outside air for cooling miners is "effective", but tons of filth gets all over everything pretty quick. So, putting together some fans + filters to...

    Hi, Looking to sell some Vega 56 and Vega 64 GPUs. Good working condition. ========== Used for mining for a few months. Fan speeds always kept to maximum, operated in a datacenter environment with proper cooling. Typical core temperatures have been kept well below 60c. All Vega 56's have...

    [Software] -- Electroneum Daemon sucks -- ideas?

    Heya. Some of you may have noticed that cryptopia has had wallet issues recently with ETN. But, they're not the only ones. Tradeogre and qryptos recently started trading ETN as well, and their wallets have had sporadic issues as well. As some background, I'm self-pooling electroneum, as well...

    Crypto Blood Bath? Mining ideas...

    Crypto prices seem to be going off a cliff, as well as mining revenues. Mining revenues "per hardware" are down 50 - 70% vs 2-3 weeks ago. Crypto prices are in a similar boat -- down 30-70% vs 2-3 weeks ago. Any coins bucking the trend? For gpu mining, Lux was a good alternative to zcash for...

    Burstcoin Plotting

    Monero private pool?

    Any interest in a private Monero pool? Aeon profits on many CPUs are no better than Monero now, and it's harder to trade Aeon. I could see myself switching back and forth depending on profitability. Would be nice to be part of the same group effort here on ServeTheHome whether I'm doing Aeon or...

    Open source cuda / nvidia zcash miner?

    It looks like everyone is using EWBF, which is closed source. Is there an open source zcash miner for GPUs that performs reasonably well?
