    ASUS P104-100 Mining GPU Review – Mining on Steroids 40+ Mh/s

    Posted: 24 Feb 2018 05:24 PM PST

    Any of you guys have issues with SSD’s failing for seemingly no reason?

    Posted: 25 Feb 2018 06:54 AM PST

    I've had two Samsung EVO 250 GB SSD's die within 30 days of purchase and I find it strange. Have any of you had similar issues? I've got 6 x 1070 ti's, a dual core Celeron, 4 GB ram, 1 x 750 W and 2 x 650 W with add2psu (each psu powers two GPU's and the 750 powers the Mobo and SSD), and an Asus z270p. My rig is really stable and I have no issues otherwise.

    Better to have higher fan speed or higher temps?

    Posted: 25 Feb 2018 04:42 AM PST

    I have an ITX 1070 that lives to run hot on me. Is it better for the life of the card to set my max temp at 70 and have the fan always at around 90% or set the max temp at 75 so that I can give the fan a bit of a break?

    People who use HiveOS, how do you control GPU temperature?

    Posted: 24 Feb 2018 03:38 PM PST

    I just switched to HiveOS, and it seems great so far with one exception. If I leave the fans at default, the temperatures skyrocket and the fans don't seem to ramp up to compensate.

    So I started by adjusting the power limit to decrease temperature. Trying to keep them under 75 degrees. I managed to do that with lowering the power limit, but the fans hardly seem to react.

    I tried manually setting the fans to like 75%, and my temperatures start lowering drastically. So I realize if I put the power limits back to default, and just set the fans manually, then I can keep the temperature under 75 and have better hashrates.

    The only problem is there are a lot of things that affect ambient temperature. So what happens when my GPUs heat up due to ambient temp increase, and my fans are set manually? Nothing - the fans are set, so the temperature will just go up.

    How hard can it be to add linear fan control to HiveOS? When the temperature goes up, the fan speed goes up. Or even a simple PI loop with setpoints? Or even an offset just to increase the output on whatever sort of control is currently being used. Literally anything at all would make HiveOS the perfect mining OS. This is the only thing I have found that bugs me.

    I am not sure what I'm going to do tonight, because the temps usually go up at night where my miners are stored - I guess I will manually set the fans really high for now...

    Can we default AMD drivers to compute mode?

    Posted: 25 Feb 2018 07:36 AM PST

    Hello friends,

    Manually changing each GPU to compute mode from AMD settings is annoying. Especially with a lot of cards and when it bugs out and doesn't change without rebooting.

    Is there a way to make compute mode the default? I was thinking maybe something in the registry can be changed. Even if it's per card, a reg file I think would be easier.

    Otherwise is our only option the beta blockchain driver from August? Is there any reason to use latest drivers instead of the old blockchain driver?

    PiHole users warning - blocked pools

    Posted: 24 Feb 2018 11:49 PM PST

    Warning for users who use a PiHole on their network It seems there has been an update to one of the domain blacklists, zpool.ca, ahashpool and nice hash are included in the list, i lost a few hours of mining because of it.

    disabling the blacklist "https://mirror1.malwaredomains.com/files/justdomains" seemed to get everything up and running again. alternatively you will need to whitelist all the mining domains that you use

    Update: turns out it was the blacklist "https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts" see issue https://github.com/StevenBlack/hosts/issues/509 which has been resolved. It is still worth adding your mining domains to the whitelist or making sure your mining rigs dont use the PiHole dns

    what's everyone mining!?

    Posted: 25 Feb 2018 06:41 AM PST

    I say thius because although zcl or eth may be most profitable for you, maybe some are mining smallller coins with potential for increase? or maybe you're converting it all into another coin?

    just curious

    Problems with sgminer on AMD rig

    Posted: 25 Feb 2018 04:37 AM PST

    Hey Guys, I'm having a frustrating issue with sgminer. I'm running 5 vega 56's flashed with 64 bios on the latest blockchain driver. I'm doing profit/pool switching with Awesome Miner and need to be able to have consistent performance on all algos or risk losing quite a bit of potential coin.

    The issue is that sometimes everything that I benchmark (or watch actually mining) with sgminer will drop to about 10% of the performance I know I can get. Things will be running great at full speed, drop to 10% and then go back on it's own. This can happen over several hours or minutes with no discernible pattern.

    I've tried rebooting, card re-init and re-installing sgminer. I've run different versions of the miner (GM and NH latest) back to back and they both mirror the issue at the same time. So far I can't seem to force it back to full hashrate. When the issue is occurring all of my other mining programs still run at full speed and experience none of the degradation.

    I'm really scratching my head here, any ideas?

    Thanks in advance for any assistance you can offer!

    Dude they do something to nuke Vega 56s?

    Posted: 25 Feb 2018 02:56 AM PST

    I moved my Vega 56s to a different rig where they'd be cooler.

    And now, no matter where I have them, I can't overclock them as much as before, like my bios flash to Vega 64 bios didn't happen, despite atiflash saying they are installed. The weirdest thing is that Wattman looks different, the layout is different, even though I installed the drivers fresh from the same installer that's been on my SSD for 4 months. Was there some kind of Windows update that made it so Vega 56's with flashed bios got sent back to being Vega 56s? I lost a significant amount of hash power, and now they are running even hotter than before. I spent the last 6 hours trying to fix it, but it seems impossible.

    I'm desperate here, does anybody have any ideas?

    Not a MASSIVE drop - but anyone else notice you can find reasonable deals on GPU Units now ?

    Posted: 25 Feb 2018 02:52 AM PST

    That didn't last long - I expected to have to wait until May/June to see even where we are now ... Save hat mined crypto in the meantime - invest in cards out of pocket. KEEP ALL MINED CYPTO.

    In 3-4 months it will pay off handling it this way .

    Suggestion on rig to build

    Posted: 25 Feb 2018 01:03 AM PST

    My electricity costs are .04 USD per KWh, so I efficiency is not a major thing to consider, but I was wondering what everyone suggests. I currently have a 6x 1080ti rig, and looking to add on

    RX570 low hashrate

    Posted: 24 Feb 2018 05:34 PM PST

    I am struggling to get hashrate above 27MHs for any of my 4 RX570 cards. I've done the bios mod (copying 1500 strap/1750 for non Samsung memory). I also tried one-click bios mod with new Polaris editor (same results).

    I am running with overclock 1100cor/2100mem. Best I get is 25-27Mhs with ethminer.

    I see people bragging about 30Mhs..how??

    Any suggestions?

    Questions OC’ing with SMOS

    Posted: 24 Feb 2018 11:06 PM PST

    I have 3x1070, 1x970 and 1x1060 running using SMOS and before I optimize the GPU's I'm getting about 1700 sol. 1070#1-385 sol, 1070#2-405 sol, 1070#3-440sol, 970-225sol, 1060(3GB)-245sol.

    When I start OCing my numbers do not change at first and then they start to go down?! Weird as hell.

    I just changed over from windows recently and am still learning so I apologize if I have asked a stupid question. Any help is appreciated. Thanks in advance.

    What's your set up, hash rate, and daily earnings?

    Posted: 24 Feb 2018 09:06 AM PST

    Sorry if you guys don't like to disclose some of these things, I'm new to the sub

    Thinking about building a rig, I have most of what I need besides the gpus and I'm curious to what works best and how well it works in the real world

    Also, what coins do you prefer to mine?

    Hive OS Or Windows 10

    Posted: 24 Feb 2018 06:21 PM PST

    I currently run a rig off of windows and mining with nicehash, is it worth switching over ? I see the Remote Desktop feature on there and it is much easier then getting it on windows 10

    Best practices for protecting equipment?

    Posted: 24 Feb 2018 05:14 PM PST

    What should be done to protect mining equipment from electrical issues? I'm particularly interested to know how people using PDUs are implementing surge protection. And how about voltage regulation?

    Return on investment on a mining rig

    Posted: 24 Feb 2018 08:16 PM PST

    I have a computer with 3 TITAN X GPU (Maxwell generation, so not best for mining) - I built it for 3D rendering, not mining- but since the GPUs are idle most of the time I decided to put them to work.

    I have just started mining (yes, I know I am starting a few years too late)- given my hardware it seems ZCASH is the best option (I would love opinions on what coin makes most sense to mine with my setup), so I gave it a try- at 1100 Sol/s it looks like ~$4 a day profit...

    Not much, but that was with no investment in hardware- just using what I had already.

    At this time is it reasonable to invest in a rig? I see claims of 10 months for a return on investment- but would I really be able to expect that? *EDIT: If I include difficulty change then, for zcash anyway, I never break even (unless the coin increases in value considerably as I mine)

    If I build a rig with 4 1080ti GPUs for say $5000 and it gives me 2800 Sol/s then it looks more like 15 months - I am new to this, and would find building and running a rig fun, but cant justify it unless there is a fairly reasonable expectation of breaking even at least...

    In short- at this late stage is it reasonable for me to get into gpu mining in a more serious way...?
