    Anyone know what Herman Miller chair this is?

    I'm looking for a decent chair for work from home without destroying my bank account. I came across this herman miller chair on craigslist for only $700. Anyone know anything about it? I like the looks but not sure about the ergonomics.

    Ryzen 7000 Series Efficiency

    I picked up a 7950x to do some testing with. With the node shrink I was hoping for something like 20% gains in efficiency vs ryzen 5000/3000 series CPUs. So far these are my results: Bottom line up front (Should I buy this for mining?): No System info: Motherboard: Asrock x670e Lightning...

    RTX 3080 ($800 - $180 in newegg credit = $620)

    I bought one of these from newegg awhile back, unfortunately before this deal came along; no perfume smell on mine either. Above-average construction quality & packaging with average cooling. VRAM temps aren't as high as some of my other cards while mining but I haven't done any stress...

    Yes, you can run over your GPU with a car

    Some of you might think a 5,000lb SUV running over something like a fragile GPU would destroy it, but fear not. You too can safely run your GPUs over to your heart's content and they (*may) not be any worse for wear. The story: I bought a GPU from NobleX13 and USPS decided to throw it in the...

    RTX 3060TIs with Hynix v2 memory @ 65MH/s+

    You can identify these cards by the "6B" in the BIOS/memory details (ie. 94.04.6B.00.A0 = hynix v2 memory). I don't know if there are specific model numbers that help correspond to this (probably not), but one of my MSI 3060TIs has it. Best case, you can probably get around 65MH/s at 140W...

    GTX 1xxx Series GPU Liquidation (1080TI), server cables

    5800X3D Hashrates

    I just picked one of these up at microcenter today for testing purposes. I have it running in my x470 gaming plus max motherboard using a beta BIOS and CL14 3200MHz memory with a stock wraith cooler. Preliminary testing at 85W PBO limit is: randomx: 8.7khash/s (about the same as my other 5800X)...

    CPU Mining Builds (My adventure with Epycs)

    I thought I'd share my results of exploring sketchy ebay & alibaba listings in search of higher CPU hashrates in randomx at a low cost. (These results are basically the same for raptoreum except you can save money by using slower memory / less channels) I basically narrowed things down to a few...

    WTB SAS Drives

    Anyone have some available? Looking for sizes around 6TB - 12TB, 3.5". I can fit two per server so maybe up to 6 total. I'm running an LSI 2308 controller so I think either 4kn or 512e will both work. Price target is about $10/TB. Trying to setup some fileservers in Raid 1 so I can stop messing...

    Home network got hacked, investigating the cause/infection?

    So somehow my home network got hacked into and I'm looking for any ideas on how to track it down and determine what to do to fix things.

    Xilinx C1100 FPGA (ETH & KASPA)

    I just picked one of these up and wanted to do a write-up since I haven't heard much about them and info is kinda scarce. Pros: -Very efficient at mining ETH (on par with an A11 Pro ASIC roughly at around 1.25W / MH) -Can be reprogrammed for RVN, etc. algorithms -Open source bitstream from...

    CPU Version of whattomine?

    Has anyone come across something like whattomine for cpu mining? The closest I've found is https://www.cryptunit.com/ One thing I kinda like about it is you can input a hashrate in one algo and I guess get a rough estimate of other algos and a profitability estimate of different coins. Not...

    How do you manage your IPMI etc. credentials?

    Thought I'd throw this out there to see if there's a better way to do things. I've slowly been getting into server hardware and it's a completely different world in terms of complexity. IPMI and remote troubleshooting and management features are great but just adds yet another layer of...

    1U Power Supplies for Servers?

    Anyone have experience with small PSUs (mini-ITX / 1U form factor) with enough output for about 300-400W of CPU usage? It turns out there's a computer recycling warehouse down the street from me so I have a consistent supply of $40 servers. They're all generally fully functional but are ancient...

    My Latest creation

    I thought I'd share this. I've been researching moving everything into server racks so airflow is easier to manage. My last test with a tesla s1070 system didn't really work out. I think it's possible but I've heard you need to have at least 1 of the original GPUs inserted for it to work...

    Safe to run GPU without VRM heatsinks?

    Normally I wouldn't do this but I'm trying to test out a build using 1U and that doesn't leave a lot of room for GPUs. I have a semi-functional MSI vega 56 but I need to remove the cover and metal fan shroud that doubles as a heatsink for the misc. parts for proper airflow. The black metal part...

    A more advanced ebay scam

    So apparently the mechanism of the scam is this: Scammer lists some cheap items to get real feedback. Then they start listing expensive items to scam people on.

    GPU Pricing Trends

    I stole this from reddit but for the past couple of months some user has estimated that GPU prices have decreased by about 20% per month. This matches up with what I think everyone is seeing in the market, but since then it looks like prices might be bottoming out for now and even going back up...

    Supermicro X8DTE-F & Linux Mining Distros

    I have 5 of these, tested and running the latest firmware (4/5 tested, testing the 5th once I get more PSUs). Setup is easy on these models since they're DHCP enabled and have an updated web interface. Fan noise isn't terrible because they throttle down to about 25% typically, but still not...

    WTB Ryzen 3600, 3700 etc. CPUs, DDR4 3600 Memory

    I'm looking at buying 4-5 Ryzen 3000 series CPUs. Preferably 3600 or 3700 ones, but I could stretch for a 3800 / 3900 series if the price is good enough. Also interested in DDR4 RAM if it's 3600MHz+ and <$80 / 16GB.
