    Biostar TB250 BTC Pro won't boot

    Posted: 15 Jan 2022 01:38 AM PST

    Hello miners !

    I'm reaching to you because I'm in a bit of a pickle. We've tried all we could, but we're seemingly unable to start our new mining rigs. Here is the setup:

    CPU: tested with intel i3 9100, i3 6100T, i3 8100T

    RAM: Corsair DDR4 Vengeance 2400Mhz

    MB: Biostar TB250 BTC Pro

    SSD: PNY 120Gb

    PSUs: 3 HP 1200W and one HP 1500W server PSU

    Atx 24pin adapter: DC 12V 160W ATX 24-Pin Pico 6-Pin Cable from miningwholesale

    Breakout boards: X11 from parallel miner

    Risers: Ziyituod PCIE Riser 1X to 16X Ver 009S

    GPUs: 12 times Asus RTX3090 TUF Gaming OC 24Gb

    OS: HiveOS

    I've set everything up and checked the motherboard's manual a hundred times, everything seems in order to me.

    When first powering up the PSUs, the CPU fan spins a few seconds then stops. After we press the power button, the CPU fan spins continuously. We don't get any video signal nor any LED lit on the motherboard.

    Since the Pico adapter only has a single Molex and the motherboard requires two, I had to use a doubler. I tought this might be the issue so we tried powering the Molex on the MB from a seperater cable to the PSU. Nothing.

    I tought maybe the 5V pin is required, so I soldered a step down on the cable and adjusted it to around 5.15V. Again, nothing.

    We tried unplugging all the risers, no difference.

    We tried pretty much everything with the Molex cable, no difference.

    We tried clearing CMOS and repeating all the previous steps, no difference.

    We tought it might be the motherboard (altough it is brand new). But we have another machine with the exact same specs (just waiting for some more GPUs) and It has the exact same behaviour...

    We're out of ideas at this point, but I'm sure you'll have plenty !

    Thanks for your help and if you want any other detail, I'll edit them in.

    2070 SUPER - Mining ETH, 35.62 Mh/s, how to improve?

    Posted: 15 Jan 2022 12:36 AM PST

    Hello,

    First of all, should I mine ETH? or maybe something else?
    I made 0.00010923 ETH in 6 hours, which means ~0.3$.
    I'm using t-rex and binance pool.

    These are the file properties:

    t-rex.exe -a ethash -u *REMOVED*-w *REMOVED* --coin eth -o stratum+tcp://ethash.poolbinance.com:1800 -p x

    pause

    Thanks for help

    Has anyone ever tried those high wattage AliExpress/Alibaba PSUs?

    Posted: 15 Jan 2022 04:09 AM PST

    I recently bought an extremely cheap server case as well as a power supply from a retireing miner for less than 100€ and it came with one of those 2000w psus,

    I'm wondering has any of you that's a bit tech savy / knows electrical tried any of those psus?

    I'm aware that they either probably won't have the advertised wattage / efficiency (the 95 gold always tears me up tbh) and also probably won't have a lot of the safety features/checks.

    But has anyone ever done the gamble and done a teardown of the psu / ran a rig on them?

    Aorus 3080 Master Rev 1.0

    Posted: 15 Jan 2022 04:02 AM PST

    I have the gpu in the title and I had mined with it for about a year and stopped mining on and was going to change the pads on it again. I originally changed them to 3.0 mm on the backplate, 2.0mm on the front memory modules and 1.0mm on the rest. I tried to change them to better ones with the exact same measurements but now the core isn't touching. When I change the front to 1.5mm the core temp stays low when gaming but it's unable to mine at all since when it is 1.5 mm on the front the memory modules are not touching. I have basically burned $150 on pads trying to get the correct configuration again but it's basically making me choose between core or memory not touching. Has anyone had similar issues with this GPU?

    3080 Ti Payout fluctuations; Mining advice

    3080 Ti Payout fluctuations; Mining advice

    Posted this on r/EtherMining, but got nothing from it, so I will ask here.

    Hello. Last week I got my hands on a 3080 Ti and I've been tinkering with it for a while now on German electricity prices (0.33c/kWh) and I still have no idea if it's even profitable for me to mine. I'm using T-Rex miner and I've started dual mining ETH+CFX and MH/s is mainly affected by power (100% needed for high rates). I tried ETH only, but I almost certainly get "LHR detected" (unlike ETH+CFX) and then everything goes to... I tried RVN mining, but I feel like the MH/s is too low. I'm not a fan of going 100% power (360W) for maximum MH/s on these prices. Currently mining through NiceHash, because I can use VPN and mine without any issues. My questions are:

    - Are such fluctuations in the payout rates normal?

    - Is ETH-Only mining more profitable?

    - Is dual mining more profitable? (Is there a way to calculate or NiceHash's profitability is the only way?)

    - If you have any advice, feel free to add it.

    - Is it at all worth it to mine in Germany as a whole on these prices? (considering these fluctuations)

    I've included pictures. I've read a few forums and I've watched a few videos on overclocking and such, but I still feel like I can't use the card to its full potential (mainly because of NiceHash's profitability calculator + some other calculator + other users' hash rates).

    Can my GPUs be repaired?

    Posted: 14 Jan 2022 11:07 PM PST

    I have 4x R9 280x cards collecting dust since winter of 2014 because I ran them too hot one weekend while I was away. Some of the connector pins burned, and plastic melted. They may still be working though, and somehow I might be able to get some money for them. Any idea what's the best course of action? How can I repair and sell them? I'm surprised they're fetching as much as I paid for them all those years ago.

    16x 1070Ti and 2x Asrock h110 pro BTC+ boards. How do I get these stable?

    Posted: 14 Jan 2022 07:04 PM PST

    Like the title says, how do I get these stable?!

    I have tried and tried for months to get these running on hiveOS but they keep crashing.

    I'm so tired of rebooting and upgrading in the hopes they will stay up. I turn to you Reddit! How the hell do I keep these cards mining?

    I have 16 msi 1070Ti 8GB cards. At most I can get 12 up for a day or so before I have to give first aid.

    Help!

    Edit: i have 12 cars running on one mobo at the moment because I'm sick of fighting with two rigs. 4 cards are sitting dormant basically. ಥ_ಥ

    Hashrate Sum By Coin As Timeseries

    Posted: 14 Jan 2022 10:45 AM PST

    Noob getting up to speed here. I see in whattomine.com you can see the current net hashrate by coin. As I understand, nethash is the net amount of required work required to process everything per second..

    So if the ETH hashrate is 956 th/s , what is the actual allocated computational power to this requirement? Are the sum of mining pools typically less than, equal to, or more than this hash rate?

    My ultimate goal was to be able to understand how much mining power exists between all mining pools, vs the demand of the top major coins. I wanted to do do some basic math to quantitatively understand the order of magnitude of power that will flush into the other coin segments.

    Thanks for your help. I'm sure I have some of this backwards :)

    RMAed 3060Ti nonLHR got back LHR version

    Posted: 14 Jan 2022 01:07 PM PST

    My old 3060Ti nonLHR just bit the dust after only 1 year of mining. I was getting about 58Mh/s at 130 watts with -200 and +1100 on the overclocks. The temperatures were always in the low 50s, I thought it would last years like my trusty 1660Ti but it stopped working after about 1 year of 24/7 operations.

    So I followed the RMA process to get another card, everything went smooth, just got the replacement card a few days ago. It's the same model, looks the same but when I fire up the mining software I'm getting 25Mh/s stock. They sent me back an LHR card. I was able to bump it up to about 40Mh/s with T-Rex miner unlock but I'm wondering are they allowed to do that? I've not only lost mining revenue from the days the card died but they sent me back a model that does half the hashrate. That ain't right.

    Won shuffle after trying for a month. But ended up not buying it cause I don't need Motherboard. Sorry guys.
