    How to decide what to mine?

    Posted: 01 Feb 2018 04:56 AM PST

    I have a few vegas and rx 580s. Initially I was swapping alt coins but ended up with a bunch of different wallets which got cumbersome. I ended up just switching to nicehash for my vegas and eth on my rx 580s. Other than whattomine, how are you selecting which alt to mine?

    GPU supply actually fell off the map this week...

    Posted: 01 Feb 2018 07:58 AM PST

    The last few weeks I've been able to grab plenty of cards using nowinstock.net. This week has been very different, however. I think supply has actually started to dry up and retailers have sold the last of their supply. Nowinstock.net barely lists ANY cards for sale anymore and I keep the page open nearly 24/7.

    How do you respond to butthurt gamers who attack miners over GPU prices/supply?

    Posted: 31 Jan 2018 08:17 PM PST

    Miners are being scapegoated now for the issues with GPU supply and pricing, I've noticed a lot of hostility among gamers both on Youtube and other social media sites.

    What do you think is they best way to respond to their anger, and have to hide that you mine with GPUs?

    Discussion on mining profitability in the next ~12 months

    Posted: 31 Jan 2018 11:38 AM PST

    Hi all,

    Just wanted to start a discussion in the subreddit on the future of mining profitability. When I built my rig, my estimated return time was 100 days, and now it's ~150 days.

    Obviously, no one can predict the future, but I'm just curious as to what this community thinks of future mining profitability. Some people seem to think that profits are going to steadily decline as new miners flood the market, shitcoins get dumped (yes, I'm looking at you, ZClassic), and a new generation of GPUs hits the market (I believe the estimate is that they will get released ~3 months from now?). Others, particularly mining veterans, seem to believe in a constant ebb and flow of profitability but generally have a positive outlook.

    Particularly interesting and helpful would be some statistics about how the mining landscape is changing. For instance, I remember seeing a graph on here of how many GPUs are mining over the last 12 months (IIRC, there are currently ~10M GPUs mining across some combination of the most popular coins and pools, with ~2M of those GPUs entering the scene in the last ~1 month. Would be great if someone could post that if you know what I'm talking about).

    I'll get the discussion started - for some background information, I'm a relatively new miner who has a 4 x 1080ti, 2 x 1070 rig, where the entire cost of my rig was ~$4500. I'm currently getting 4000 sol/s on Equihash using DSTM on Ubuntu 16.04. I mine in my dorm room, so electricity is free. My personal outlook, not particularly researched or based on any hard facts, is the following on the following issues.

    Crypto crashing - Obviously, if the total market cap of GPU-mineable coins tanks at any point, mining profitability will decrease. However, I personally don't believe in a total market cap crash. I think that the coins with the best tech should survive and that money, instead of leaving crypto altogether, will enter these coins, having a neutral effect on mining profitability. Perhaps one concern is Ethereum's PoS transition, which will flood all Eth miners into altcoins, potentially severely decreasing mining profitability - however, I don't think this is projected to happen for at least another year (someone please correct me if I'm wrong).

    New cards - Nvidia is supposed to be releasing a new line of cards that will most likely make current cards very unprofitable in comparison. However, I don't think that this should change how profitable mining with current cards is for at least another 6 months because I don't think that the quantity of cards entering the market will be large enough soon enough. Would love to see some statistics about Nvidia's production scale.

    Influx of miners - Not sure about this one. Obviously, price will need to increase to offset new miners entering, but I really don't know much about the sheer quantity of miners that are entering so I have no good opinion. Would love to see some data.

    Please let me know your thoughts!

    Officially part of the club...

    Posted: 01 Feb 2018 07:41 AM PST

    I had a small ETH rig towards the end of 2016, (2x 380) but had to pack it in and sell up due to a landlord that was convinced I was somehow breaking the law (??).

    Well I've been saving for a while and today I finally pulled the trigger on my first proper rig. For now I've just gone with one 1080, which I got a good deal on - and used the savings to pick up a 1060 3GB. Decided to splash out on a metal rack this time as well (last rig lived in a cardboard box...).

    I can pretty much manage the rig via teamviewer all day thanks to the nature of my job, but I'd still like to have a relatively hands off approach and not mess with OCing, voltage, BIOS modding etc - My question is, would I be a fool to just build the rig and set her off on NiceHash full time? I don't want my return to be lower than it could potentially be.

    Thanks for any and all advice, and it's great to be here.

    Rig crashes after starting Nicehash - "Video TDR Failure"

    Posted: 01 Feb 2018 07:30 AM PST

    Rig

    GPUs: GTX 1070 x6 (3x EVGA, 1x Gigabye, 1x Zotac Mini, 1x MSI)

    Mobo: MSI Z270 SLI Plus

    CPU: Intel G3930

    PSU: EVGA 1300w Gold

    MSI Afterburner OC Settings:

    • Power: 85%

    • Core Clock: 40

    • Memory Clock: 500

    Issue

    I completed this build a few days ago and have been gradually working through issues. All GPUs are recognized and I'm able to use NiceHash for several minutes before Windows freezes, crashes to BSOD and gives the error "Video TDR Failure." The system reboots after with no issue.

    What I've Tried

    • Ensuring solid connection between risers/mobo and risers/GPUs.

    • Uninstall Nvidia drivers using DDU. Reinstall using GeForce Experience.

    Thoughts?

    What is your longest running GPU with no problems at all?

    MSI Afterburner GUI, only shows 8 GPUs?

    Posted: 01 Feb 2018 06:33 AM PST

    I've recently set up a 12 GPU rig, and the Afterburner GUI allows you to group modify settings by card type. But you cannot select cards 9-12 to individually tune them... unless I'm missing something?

    Is there a way to overcome this?

    Also, Afterburner is pretty damn laggy and unresponsive at times. Is there a better overclocking utility? I've tried nVidia inspector, but saving and running custom settings for 12 GPU's is a challenge.

    Where can I find the MSRP (RRP) of graphics cards? (UK)

    Posted: 01 Feb 2018 06:12 AM PST

    As the title says I'm struggling to find out the MSRP value of graphics cards when trying to buy them over here in the UK. Is it literally just the price listed on the manufacturer website? Is there a list or similar I can reference?

    Some of these seem insanely high compared to the USD equivalent. They also seem to fluctuate a lot and I don't want to overpay when ordering some more shortly.

    Any help would be much appreciated!

    Burnt smell?

    Posted: 01 Feb 2018 04:15 AM PST

    I woke up this morning to a pretty strong burnt smell at my place. That being said, I couldn't 100% be sure it'S coming from my miner. Could be from a neighbor or outside.

    My miner was still mining fine. My temps are running OK, with the max temp being at 75 or so. I looked at my miner and everything is fine. Is this a) dangerous b) where could it be coming from?

    Thank you

    How can I improve the effective hashrate?

    Posted: 01 Feb 2018 04:00 AM PST

    EVGA raises their prices yet again.

    Posted: 31 Jan 2018 09:45 PM PST

    I've bought a few cards from EVGA as availability comes about, similar to other sites. I bought a 1080Ti, model 11G-P4-6593-KR a month ago for $739. I bought one again two weeks ago for $789, only realizing after I bought it that it was the exact same model as the one I bought before at $50 less. Now I looked again today and the same card is $849. So much for MSRP.

    It's blatantly clear they're selling nearly all of their cards to the big guys who are buying pallets. I refuse to believe they're just this backed up in production. I hope they clean up, because as a longtime buyer I'll remember this gouging later on.

    Overclocking with a power limit?

    Posted: 31 Jan 2018 08:07 PM PST

    I keep seeing people who OC their cards along with setting a power limit.

    From what I understand, the amount of power drawn is based on the GPU's running clock and voltage, and if the power limit is reached, the GPU will down-clock itself to remain within the limit. Conversely, if your GPU is running at a certain clock speed with a power limit set, raising that power limit wouldn't increase power draw at the same clock speed.

    My question is: wouldn't setting up a power limit essentially invalidate your OC and lets your card run at whatever clock speed that falls within the power limit? what's the point of having both OC and a power limit?

    My new favourite PSU: 2600W server PSU with 24 8pin and ATX connectors!

    HP Server PSU temp and noise

    Posted: 01 Feb 2018 03:03 AM PST

    I'm posting here because I'm not sure if there's something wrong with my server PSUs. I have HP 750 and 1200 watt platinum PSUs and I'm using the parallel miner x7 breakout boards.

    I've heard server PSUs are loud but I don't hear the fan when I plug one in. Does it get louder based on temperature or load? I've been testing using about 450 watts with one and the GPU fans are louder than the PSU. The PSU also feels hot, not too hot to touch but hotter than a standard ATX PSU.

    Is this normal or does it sound like something is wrong with them?

    Low hashrate, hashrate dropping

    Posted: 01 Feb 2018 03:00 AM PST

    I built a rig on my Lenovo H535. I installed the GPU's outside the case using risers and powered them using external PSU. In the case there is some low-end GPU that I use to connect my screen.

    The problem is that I am getting low hashrates and my other NVIDIA GPU has much lower hashrate than the other. In the beginning I got 280H/s and 80H/s with EWBF's miner, but when I switched the PCI slot I got 280H/s and 200H/s. I'm still unsatisfied, I'd like to get the second card to atleast 250H/s.

    Other problem is that the hashrate drops slowly. With Nicehash I can start with $5/day but after 1 hour its $2.7/day. It's the hashrate that's dropping. Sometimes when the hashrate gets low enough, it might occasionally rise, but stays under $3/day. Same hashrate drop happens on EWBF miner. According to calculators I should be able to get $7+/day.

    Temps on my card are max 72 and 47. There are 15cm free space between the cards. Could this be problem? The GPU's have two connections, one for power and other for the riser. I am using the PCI-SATA adapter to power the riser. Could this be problem? The adapter is not getting hot in use.

    Right know I'm clueless how I could rise the hashrate.

    Specs:

    GPUs: 2x Asus GTX 1060 3gb Dual OC (Driver 390.77)

    Mobo: Lenovo cfm2d3m (AMD A75 chipset)

    PSU: Default 280W, Seasonic 650W Gold plus

    OS: Windows 10 home edition

    Risers: ver006

    Mining software: Nicehash, EWBF's Zcash cuda miner 0.3.4b

    Overclocking specs: Nothing, Fans 100% (tried both)

    How to diagnose hashrate instability?

    Posted: 31 Jan 2018 04:21 PM PST

    I spend the day modifying the BIOS on 6 of my new RX570 ITX from Sapphire.

    They're all Elpida. I start off good, around 28.5-29.5mhs across the board but sometimes they dip to the low 13-18mhs. I even get some incorrect shares. I'm linking some images below for you guys to see. I'm wondering if the incorrect shares were due to undervolt, or too much clock on the memory.

    Impossible to find a 6 pin male to 6 pin male ?

    Posted: 01 Feb 2018 01:19 AM PST

    I have some risers with 6 pin to sata but I dont want to use the sata connector. The best way to do it will be to put a 6 pin to both my PSU and my risers but... i can't find this kind of cables. Any suggestions ?
