Just writing to say THANKS to everyone involved in this project, from the initial versions to the new 2.0-Community Release. I've been using nvOC for some months, and recently updated the base image to the 2.0-CR version. Everything super smooth and stable, with cool new features. The update scripts for the base image and new miners work like a charm. Keep up the good work, guys! It's an excellent case of how the open-source community can achieve great things.

Guys, I stumbled upon this little freeware app to flash image files to USB sticks:

http://winflashtool.sysprogs.com/

What I liked is the ability to resize ext2 partitions during the flashing itself, meaning you can easily make it fill the entire disk space. I tested with nvOC and a 32 GB USB stick, and it correctly resized the root partition to fill the usually unused 16 GB disk space (meaning you can use it now).

Could be interesting for people who don't want to use GParted (or fdisk/resize2fs) after flashing, and just would like to use the entire disk space for the root partition.

Good info. Nvov's root partition is ext4 but if it worked for you it must work for ext4 too.
Thx.

Yes it does, ext2/ext3/ext4, even though it advertises only ext2.

Hey guys, first, congratulations to all involved in improving nvOC! Smiley Given this new unofficial testing release, I have a few questions:

1) Has fullzero abandoned development of nvOC? Is this unofficial release going to take over and become the official one, or are we going to have two branches?

2) papampi and the others involved: are you planning to release a full image (.img or .iso) once the testing is completed?

Guys, is there a real-world difference between enabling or disabling GPUPowerMizer? I notice I can achieve the same overclocking values with or without this setting, getting about the same hashrates. But maybe it's good (or not!) for something... From the NVIDIA documentation, it's related to dynamic power management, but since we lock the frequencies and power limit, does it have any use? Thanks!

Attribute 'GPUMemoryTransferRateOffset' (m1-desktop:0[gpu:12]) assigned value 300.

There is no screen to be resumed matching miner.

What coin are you trying to mine, with which miner? In v0019-1.3, the ZM miner (ZEC) points to an invalid path in 3main. I manually fixed that in the script (or you can fix the actual path). Or switch to EWBF which works out of the box.

Thanks @dstm , this miner is giving me better performance than EWBF, even when taking the mining fee into account. With EWBF, some cards were frequently underutilized, in a random fashion. With your miner, they stay with over 98% utilization all the time.

I have recently built a new rig with 13 P106-100 ASUS cards on nv0019 running -200cc 1550mc and PL90. I have a weird problem that after some time the hashrate on all cards drop by 50% or more and doesn't go back up, the miner doesn't restart and it just keeps running with lower hashrate.  This time it did this after 7 hours , with 7 cards running it was up for over 12hours and no problems. Has anyone experienced this before and maybe you know where the problem is?

How is the temperature of your cards? Have you configured nvOC to use auto temp control? If you have, it may be the case that you set the temp too low for what can be reached with 100% fan speed. In this case, auto temp control will smartly reduce the power limit to cool the cards, but of course this reduces the hash rate. Just a guess...

Does Linux ever hard freeze?
Been using ubuntu since 2006,
Got lucky and have never experienced it.

Yes it does... Of course it historically has always been more stable than, say, Windows, but hard freezes can and do happen mostly for these two reasons: kernel (including modules) bugs, and hardware issues, as pointed before. More rarely, a bug in the "init" process can also do this. These can trigger what's called in the Unix world a "kernel panic", the equivalent of Windows' BSOD. In some cases, even in a kernel trap, you can do some debugging (like dumping memory) and take a few actions, like syncing the filesystem and rebooting, but not always.

That's one of the reasons why enterprise and "stable" distros (RHEL / CentOS, SLES, Debian stable, Ubuntu LTS) are more conservative with new kernel and software versions. They tend to use the long-term kernel tree, which doesn't introduce too many features, focusing more on fixing bugs.

Now, personally, with nvOC (which uses Ubuntu LTS) I've never had a kernel panic. Smiley But you never know, if you need full remote control this SRR seems a cool addition, or an intelligent power switch, KVM etc.

wow this is super cool. all I had to do is image the SSD and I was up in running in no time by just swapping it into a rig.

only issue is.. all ETH miners report some version of

Any ideas what this might be? I checked and there is no connectivity issue to etherminer from the box, I can telnet to port 4444

Well from the messages I'd guess a DNS issue, but since you can telnet to that host... Have you checked in 1bash if "ETHERMINEdotORG=yes"? It's necessary for Ethermine (well, at least for v18, haven't upgraded to v19 yet).

Guys; I thought of keeping all the best OC settings in one place for all the available cards in the market.

I would need your help to input your best OC finds bit of details; happy to update it time to time; it would help us hit the rock bottom (even for a beginner).

You can PM me or Post a reply on this post or request on this post :

https://bitcointalk.org/index.php?topic=2176936

Hope I get good support from our nvOC community members to make this possible Smiley

This is URL :

http://krypto-mining.blogspot.co.uk/

I've only started; any suggestions welcome Smiley

That's a good idea, congrats on the initiative! I've visited your website and would like to suggest to include a column specifying the exact brand and model of the card. And even with the same brand and model, I've seen differences regarding the maximum stable OC values, probably due to different memory manufacturer or other slight differences in manufacturing. But with your idea it will be definitely *a lot* easier to know what values should be stable, and play with slight differences.

I'll PM you soon with my cards' OC specs.

I plan to try salfter's coin switching app soon, but would like to know your experience first: what has been shown to be more lucrative, Mining Pool Hub or NiceHash? (Sorry if it's been asked before, couldn't find any previous answers.)

There was a lengthy comparison somewhere on this forum between MPH, NiceHash, and zpool that found zpool to charge the lowest overall fees and thus be the most profitable.

Cool, thanks! I'll look again in the previous pages to catch up with this discussion.

So i have an SSD with 2 partitions on it (one has windows) but HDDRawCopy doesn't seem to allow me to switch partitions. Is there a solution to this or would Etcher work better for my purpose?

What are you trying to do, keep your original SSD partitions and write nvOC as a new, separate partition? What do you have in your second partition, another operating system, or just data?

I created a second partition for nvoc but i still want to keep the windows installation on the first partition.

I don't think HDDRawCopy will allow you to do that, and I don't know Etcher. What I would do is this:

1) Flash nvOC to a USB stick, configure 1bash, let it boot at least once to have everything ready.

2) In Linux, considering the USB partition is /dev/sdc1, and your SSD partition to be written is /dev/sdb1 (examples):
   dd if=/dev/sdc1 of=/dev/sdb1 bs=64k
   (edit: may require setting the correct FS type and size on fdisk, don't know how you created it)

3) Adjust configuration files on Linux @ /dev/sdb1: at least /etc/fstab comes to my mind right now, if it uses static device references, not UUIDs or labels.

4) Install grub on the SSD MBR, configure it to dual-boot Windows and nvOC (Linux), overwriting any previous setup from nvOC. Takes quite a few steps for that, there are howtos around.

Beware that if you're not familiar with Linux and this kind of setup, it can be dangerous, backup your data first.

Now, there may be some disk-cloning utilities that automate that, including the grub installation and setup. Some of the ones I mentioned in a previous post may work.

How can I edit nvOC and then use that as my nvOC baseline --- so I can flash it onto X hard drives and all I have to change is the worker name ?

After setting up the baseline nvOC installation, you could simply create a new image of the partitions (or entire disk), and use it to flash new disks. For that, you would need to boot from a different drive, as the disk you're going to image shouldn't be mounted. I personally like GParted Live and PartedMagic, as they are loaded with several utilities for that, but you could just use the "dd" utility that comes with every modern Linux basic installation.

So: boot GParted Live from USB stick; have the disk you are going to create the image from ready; have a disk where to save the image file ready; use a partition/disk cloning utility (or "dd") to create the image; use that image to flash new disks. Note that depending on your hard drive sizes, ideally you should create images with only the used space (some utilities allow that), as it doesn't make much sense to create a (say) 250 GB image with only 10 GB used.

Finally, I don't think you'd need to change anything on the newly-flashed nvOC disks, as it automatically adjusts the worker name based on the IP address (but of course you can), and the Xorg reconfiguration should be done automatically too.

previously the worker name did not work properly for me when it was set on the auto adjust setting, did anyone else have that problem and could that have been a conflict with my router/switch?

thank you for the quick reply, is it possible to do this on windows?

Is there any benefit to periodically putting a freshly flashed USB in as opposed to one thats been mining for months?

For Windows the process would be similar: let's say you have your notebook with Win10. Plug the source drive in one USB port, the destination drive in another USB port, and run a disk cloning utility. That same disk cloning utility should allow you to create an image file to save on your notebook itself, to flash future drives. Check this website for some disk cloning utilities for Windows:

http://lifehacker.com/5839753/the-best-disk-cloning-app-for-windows

Now for your other questions:

1) Never had this kind of problem. My setup uses DHCP but with static IP assignments configured in my router, so there's a consistent hostname.

2) You PMed me with this question, but I'll reply here for others: if I understood, you wanted to know if it's possible to clone the nvOC installation before booting it at least once. I don't think it's a good idea, as there's that process to copy 1bash between partitions, adjusting them etc. (not sure if it still applies to v019). So just to be sure, boot it once, make sure it's mining correctly, then shutdown, and clone this installation.

3) I don't think you need to replace your USB drives unless they are giving read/write errors. After flashing and setting up everything, there aren't many disk writes that could wear out the drive, as far as I know.

Or... just occured me: if you are sure your 1bash settings are correct and you don't need to change anything else, simply copy this file over to your next installations. Smiley You will need to flash the nvOC img file anyways, would take about the same amount of time as cloning.

This whole process I mentioned is worth it only if you customize other things after booting nvOC, not just 1bash.

This is the scheme of my setup. Is a box 44cm wide x 32cm high and gpus are setup on two levels one on top of other. (1060 3Gb gpu)
There is a raspberry pi wich allows me to reset/poweroff-on and control the inside temps using 5 sensors DS18B20.
12 fans push fresh air inside the box. They feed on an external psu. Temps with power limite 92W are 57-68ºC.
By the way I had a big cpu load (5-14) when I had power limit to 72W. Once set to 92W got down to 1.5-2.2 (yes I know no good yet, but much better).
I use a celeron g3900, looking forward to upgrade to I3.
I post this hoping the schematic helps others like me who have their rig in remote locations.
Here the code bits for temps, poweron/off and reset.

Hey man, that's a very nice DIY project you have there! And great schematics btw, thanks for sharing. I'm wondering, how much did it cost overall (Pi + fans + sensors and parts)? Did you try integrating it with nvOC's auto temp control, which uses the GPUs internal temp sensors, instead of relying on the DS18B20?

I'm facing some heating issues here, as the days are becoming hotter, so I'm thinking about what to do. I don't want to leave an A/C on all day, because of energy costs, so probably will need something to suck the hot air from the GPUs to the outside during the day, and reverse direction at night, when it's colder outside. Your project really gives some ideas... Smiley
