    Octominer - my review and why i believe many people will love it

    Posted: 22 Feb 2018 04:03 AM PST

    im not a native speaker, pls excuse my nasty spelling

    Never ever use your riser - Octominer got recently some Hype. So i decided to order them and try them out. In this review i'll write my experience with them, from shipping to installation and how i like them.

    People like me had horrible experiences with risers. Just to make it short: i had a very ugly batch of 300 risers. After a week i had less then 100 unstable gpus running. I ended up returning 220 of those risers, just to receive the other boxes of that batch. i gave up and bought other risers from another dealer. This didn't just cost me a lot of money (missed time from mining), but it also created a lot of mistrusting against risers. That was 8 months ago. Fast forward, 1100 risers later: Octominer came to life.

    With the most recent 600 GPU farm we had some cooling/airflow issues that make me think how to improve. I decided to order a total of 5 Mainboards and 5 Cases. This would be just a small test order for us but i had huge expectations. The forwarder from HongKong declared my order as 350$. Basically it's a good thing, however the customs officer googled Octominer and declared my shipping with 1k$. I ended up paying 300$ Duty & VAT which is still cheap. The packaging itself is very good and stable. The Mainboard is packed seperately to keep it extra safe. Thumbs up for this. Comparing with the random seller on Aliexpress, this packaging gets extra points. The Mainboard was a bit smaller as expected, you can see a comparision with a regular ATX Mainboard

    Installation is very easy. Add RAM to the Mainboard (don't be like me, i forgot to do on 3 boards....). Just open the case, lay the cables for the fans between the spacings for the mainboard, place the mainboard in its position and add the screws. You can either use a ServerPSU or a regular ATX-PSU. If you use a regular ATX PSU you need to connect Pin4 and Pin5 with a paperclip. It's pin4 and pin5 on the side where the big clip is. I suggest you to tape it afterwards. If you power your GPUs you only need to connect 2x Power to the Mainboard. (if you use 8x RX560s who don't have external power supply, you need to connect all power-pins). If you want to connect the Frontpanel, i suggest you to tape the pins together to a block, then you can easy connect them (or connect them while the board is outside of the case). Add your GPUs and screw them together with the Case. I really appreciate the fact that Octominer gave enough screws with the case. You can loose half of them and still have enough. You can close the Lid now and use 2 screws to fix the PSU.

    Congratulations. In less then 8 minutes you assembled a 8x GPU Rig, which works plug&play. Octos are really easy to transport

    Next step is to add my USB Stick where i installed ethOS already. You can also use HiveOS and SimpleMining OS or your own Ubuntu/Linux. I don't use SSDs/Windows. I don't use a screen at all.

    The configuration of my rig in ethOS takes me about 2 minutes including reboot. So after less then 15 minutes the whole thing is running and i don't need to pay attention anymore. Time to assemble the other 4 Octominer For the POST you hear 5 beeps. All 5 boards booted out of the box, i never need to touch them and they run smooth. I had one Rig running 40 hours till i had to move it, so even i didn't run them for 25days+, i dare to say that they as stable as the rest of my farm (Asrock H110, Asrock H81, Biostar TB250).

    What GPUs did you test?

    I ran (and only have) AMD RX470s.

    What are the temps?

    This is the big question! The rooms of my farms are pretty hot, surrounded by Openair rigs, the Delta Fans of Octo did a great job. I know some people remove the fans of their GPUs and let just the heatpipe work. If you feed your rigs with fresh/cool air, Octo will outperform any open air rig by a lot. In one of my rooms i can't go on Ethereum, as i don't have strong enough blowout/airflow. However, i put 4x Octo in there, going for Ethereum. My 470s did 64-68�C which is really good. In a dedicated Octominer-Room where i have a wall of them and use them like Asics, i'm sure i can drop those Temps down to 60.

    Is it loud?

    Yes. It is too loud to have a rig running in your bedroom. They stand out from the mining-room at home where i used them. When you use Big Blowouts (45" up), you won't hear them anymore. I suggested Octominer already to provide an option to reduce the DeltaFan speed. Best would be a slider in front of the panel. Propably cost 10$ more?

    But it is so expensive! No, it is not. If you call it expensive, i will call it worth it! I will do some math for you, based on our new 600 GPU Farm, the prices are based on what we did pay and we can compare that if we would have build on Octominer: https://i.imgur.com/flEeo94.png Yes, of course we can also run Server PSUs instead of ATX, we could argue forever. However, let the Octo thing cost 10k$ more, we would order instantly, it's a nobrainer for us. We recently need to reduce OC a bit, to keep the whole farm stable because of the overheating. With octo, this would not happened. We would simply have a Wall of Octos , blow fresh air to them and vanish the hot air, coming out behind them.

    Why then you say it's better? What really scores is the density we can archive with Octominer. Please check the two images where we compare octo to our regular layout (i swear, i will remove the zip ties soon!): https://i.imgur.com/FK7eiwn.jpg, https://i.imgur.com/Z0d2AJk.jpg

    A regular Rack with 4 rigs is 115cm wide and 180cm high. We host 4 Rigs, each 12 GPUs = 48 GPUs per rack.

    We could use the same space with octominers If we would do simple math, for the same space, we could do 63=18 Octos, that's 144 Gpus. To make a 600 GPU Farm, we could simply make a *wall of octos and vanish the hot air that goes out behind. It would be so much easier for us to cool all these. There is a reason, why Genesis Mining build their new Farm on similar cases. This is actually priceless. Beeing able to control the cooling of such an amount of GPUs is not easy. With octominer things become very easy. This is a lot worth for us.

    Never change a running system, but we currently think about upgrading our new farm completely to Octominers. For sure, the next mining rooms we build are 100% based on Octominer. I believe we will see a lot of other people doing just small test-orders and then immediately upgrade their farms.

    Water cooled Mining rig! 12x 1080ti EKWB

    Posted: 21 Feb 2018 11:28 AM PST

    Rig randomly "quits" for seemingly no reason

    Posted: 22 Feb 2018 05:17 AM PST

    2x MSI gaming x 1070 1x EVGA FTW3 1080 ti EVGA Supernova 1000w G2 MSI 270-A Pro mobo

    I have been mining since December with my 2 1070s on MPH with Multipoolminer with virtually no problems. Recently, I have upgraded my rig and added the 1080ti. I have had problems since. I have done everything; uninstall/reinstall drivers, MPM, etc. However, no matter what I do, the rig will not mine for a long period of time. I have two windows open while mining; Afterburner and MultiPM script. I will check back after 2 hours or so to find the rig is still functional, just sitting at the desktop, but there are no windows open and both Afterburner and MPM have closed somehow.

    Thinking this may be a power issue or OC issue, I have tried running the rig at default settings, even running the 1070s at 75% TDP (what I've been using since December) and the 1080ti at 100%, both with zero clock/mem upgrade.

    So, if anyone has any suggestions I would love the help. Thanks

    For those of you running SMOS I have a couple questions

    Posted: 22 Feb 2018 05:40 AM PST

    1. Can I run smos on my ssd vs flash drive.

    2. Do I need a virtual page file in smos like I do in windows?

    3. If I need a flash drive how big?

    Thanks! :)

    Contest: Win my mining rig for a week

    Posted: 21 Feb 2018 09:38 AM PST

    My son is doing a donation drive for his school and I was trying to think of a way to get him some action on it. Being a typical computer nerd I have no social life so not a lot of friends to ask. So as many of us do, I turned to the internet for help!

    So I thought up this contest to help him reach his goal. I have a rig with 4 1060s and 2 1080s that I will point to any pool/address the winner of the contest wants. To enter the contest just comment on this post and when this post is 7 days old I'll do a random sort and whoever's name comes up will get my rig for a week.

    No donation is required but I would love if you threw a buck or two at my son's donation drive. http://www2.heart.org/site/TR?px=10073650&pg=personal&fr_id=3190

    EDIT: Amazingly Amercian Heart Association doesn't accept crypto, yet. If you want to throw crypto at it I will convert everything going to these addresses to cash and donate /w your username (assuming its safe to display on a child's donation charity page :)

    Btc: 17KVexnNubHWBj3Cj9YcCAFYbiqyVzgxne

    BCH: 1HZViqu9LHt8KoRkp4CSDp4gGEBipac8j7

    Ltc: LNXtmy8tihfmwos8w1LkQYt6zH97tAgPPs

    Eth: 0xF02De47f6e0b3FF4CfaAC34038e580A0D5537c97

    Xrb: xrb_145ghiuububwzo9mzi19nenagocu1afqhbboa5wxuz49mua7m5hh8ccm85nr

    TLDR: Comment in this post. In 7 days ill do a random sort and point my modest 6 card rig to w/e pool/address the winner wants for a week. Would love a donation but is not required.

    Overclocking: Windows 10 stuttering or miner errors?

    Posted: 22 Feb 2018 01:39 AM PST

    So I've been getting 2 kinds of errors from overclocking my 1060s (3 if you count the rare crash). First is Windows 10 stuttering. The miner program (claymore) will continue to run, but Windows will stutter, only doing stuff in "bursts" every few seconds.

    But I've also overclocked the memories to the point where I got share errors in claymore.

    What gives? Are these both the result of overclocking, or are there maybe fixes for stuttering? Because I want to try and push my cards a bit more.

    How to specifically select a gpu for gaming and other 5 for mining?

    Posted: 22 Feb 2018 01:32 AM PST

    Ok, maybe I don't have to do anything for the mining part as in nicehash I can already select those, but how to specifically select a gpu for gaming? How would window know which is the main gpu to be run with when I started playing game? Please advise.

    I can't set auto profit switch for Equihash into Hive OS

    Posted: 22 Feb 2018 07:07 AM PST

    Can anyone help me ?

    To me, all is good, but i've got nothing on MPH.

    I have configure my wallet with my MPH username, with the correct port (17023).

    And on MPH i added a new worker (myusername.thenameofmyhiveosrig) with profit switch to equihash. Right now it is zclassic that is the most profitable. But i've got 0 h on my dashboard. What could be wrong ?

    Pic of my first custom built mining rig. As some of you can probably tell, it is certainly not a professionally done job, my cable manageent is shit and the motherbord is literally just laid down on a few pieces of wood.

    Starting a PSU without mainboard (paperclip trick doesn't work)

    Posted: 22 Feb 2018 05:49 AM PST

    I recently bought an 850W Platinum PSU from Aerocool (https://www.aerocool.com.tw/en/project7/psu-p7/p7-850w-platinum) and I can't seem to get it to start without a mainboard attached. The paperclip trick doesn't work, the PSU starts up for a second and switches off immediately. Does anyone have another trick how these things can be started? Google turns up nothing but paperclip tricks.

    Cryptonight mining malware found on my rigs

    Posted: 21 Feb 2018 10:39 PM PST

    Guys beware there is a XMR mining malware infecting mining rigs (windows). I have not installed anything but mining softwares here. Lookout for someting like cpu.exe using like 50% cpu and mining xmr. its not easy to remove without malware tools. i installed malware removing software called malwarebytes and uninstalled that app later.
