One other possible option - grab the 521 OpenCL client from the Distributed.net downloads, rename the exe to match the 520 .exe client in data/projects/Moowrapper.net, then copy the renamed 521 client over the existing 520 client.

I had one machine that just wouldn't run on the 520 client but ran fine on the 521 for some wierd reason I never did figure out.
22) Message boards : Number crunching : Vega (Message 7771)

Got my Vega 56 in today (Sapphire reference model).

It's WIERD - to get it to get anywhere near the officially specified "1590" core clock, you have to kick the power limit WAY up (+30% at least in Afterburner) AND you have to UNDERVOLT it quite a bit (-100mv ballpark) - and even THEN it won't get to 1590, though I did see mid-1500s after a bunch of settings work.

In stock form, it's not quite a 8 Gigakey/sec card (for perspective, the GTX 1080 ti can hit a little over 10 GKeys/sec with some overclocking).
Maxed out, I saw about 9.5 GKeys/sec though - which is not bad at all for a $460 card compared to the 1080 ti at $700+, and quite a bit more than the GTX 1080 manages in the same price ballpark.

Card also runs AMAZINGLY cool unless you push it very hard - never much past 55C at stock settings with less than 55% fan, and the settings I found to make it a 9GKey/s card was only pushing it to about 62-63C at under 68% fan (I run a straight-line "fan curve" in Afterburner by default that is "all in" at 80C and drops 20% every 10C below that).

I estimate that a stock 56 will exceed 1 million RAC by a bit, a pushed one should get into the 1.3-1.4 million RAC ballpark - in other words, a SINGLE CARD can exceed all but about the top 3 or 4 machines currently working Moo Wrapper.

Given wide reports that the air-cooled Vega 64 clocks higher reliably than the 56, and that it has 64 CU instead of 56 (1/7'th more cores), I am ready to state that the Vea 64 SHOULD be the current Dnet/Moo Wrapper single card performance king - especially if someone wanted to put out the kind of money to get the WATER COOLED version, which supposedly clocks a LOT higher than the air-cooled version.

The distributed.net client ITSELF does not support NVidia well if at all in versions prior to 521.
Yet another reason MooWrapper NEEDS to get updated to 521 asap - it fixed a TON of issues vs the version 520 client MooWrapper is currently using, and offers a LOT better performance on NVidia cards.

Try backing out to the 16.9.2 or the 15.12 drivers - the Relive junk has a LOT of issues where it works at all, and a LOT of the newer driver versions flat out don't WORK with R9 series hardware.

download the Distributed.net 521 client from https://www.distributed.net/Download_clients
Unzip the downloaded file
rename the dnetc.exe file to match the long file name dnetcxxxxx.exe file in the boinc projects/moowrapper.net directory, then copy it in place of the existing file.

Since moowrapper WILL overwrite the file on occasion, keep the renamed copy of the 521 client file around for later recopy.

Posted 6 Oct 2017 by QuintLeo
Post:
I'm not sure if OpenCL on NVidia is properly supported by the dnet 520 version of the client Moo Wrapper uses - it's one of the reasons I've been strongly in favor of Moo Wrapper upgrading to use of the CURRENT 521 dnet client, which definitely DOES work correctly with NVidia.

You may also have an issue with the driver version you have not having initiated OpenCL support correctly - there were a couple of NVidia driver versions that had that issue, backing out to around 378 seems to help (and if you're not GAMING on the same machine they run more reliably as well).

It's just the way mixed GPUs and their drivers interact - or the Collaz application was soaking a lot of CPU cycles as well (like FAH does).

Try the 15.12 drivers (15.300.something under LINUX as I recall) - the version you are using is the 15.7 which wasn't quite as stable on your generation of card.

Same advice if you're running Windows - the only later Windows drivers that were worth spit on older R9 series cards were in the 16.9 to 16.10 range, and those have NOTHING to offer an older card unless you also game on the machine, while being noticeably more bloated for similar performance.

You may also be overclocking the core a bit too much, the Dnet.c client is notorious for how hard it pushes the core of a GPU (while being VERY VERY light on memory usage).


WAY back in the day, it was often debated if the Dnet.c client or the Prime95 (GIMPS) client was a better stress test.

Post:
Why did the "Your Computers" page stop showing the NAME of the computer?

This makes it a royal PAIN trying to figure out which machine has gone down, especially since Moo Wrapper (and BOINC in general) never seems to identify the GPUs in a machine correctly to the various stats pages.

If you are on Windows 10, you probably got auto-updated to a driver version that doesn't work well on older hardware.

I can't tell for sure as that reported "driver version" doesn't match up to ANYTHING I've ever seen before.

Posted 10 Jul 2017 by QuintLeo
Post:
Unless you are doing CPU computing, there is ZERO advantage to a 64-bit version as your GPU(s) are doing all the work.

There is NO "gpu-based" DNet client that is 64 bit for that reason, all of the 64-bit clients are CPU-specific (and very SLOW even on current CPUs compared to very old GPUs).

Hopefully it's a different issue, but it appears that Moowrap stopped talking to the Distributed.net keyservers to report block ENTIRELY sometime early on July 8.

Post:
It wouldn't be practical on Moo Wrapper to run one work unit on multiple GPUs even if BOINC specifically supported it, as Moo is nothing more than a "wrapper" for the Distributed.net client that client does not support running one "block" on more than one GPU at a time.

It's possible to have AMD and NVida GPUs mixed on a Linux machine - but an AMD GPU MUST be the one used for video output, you MUST install the AMD drivers first, THEN install the NVidia drivers from the .run package MANUALLY using the "--no-opengl-files" command line switch - otherwise the NVidia opengl stuff overwrites the AMD opengl stuff and completely borks the AMD drivers to the point the AMD GPUs flat out won't work at all.

In theory you can hand-install the applicable files but that's a royal pain at best and will leave you with an unusable system if you miss even ONE of them, or use ONE wrong file.

Mixed GPUs is one of the very few things Windows does better than Linux, and IMO one of only 2 things it does a LOT better (the other being "support games").
38) Questions and Answers : Windows : R9 270x failing (Message 7680)
Posted 20 Jun 2017 by QuintLeo
Post:
Google search on 15.12 catalyst *should* find the AMD download page for it - unless you are running on XP or older Windows version, or perhaps a Mac.

As I recall from the rebadge between the HD 7xxx series and the R9 2xx series, your 270x was the HD 7870 in the previous generation - I've got *2* of those cards been running Moo for quite a while now, under both Windows in the past and currently in a LINUX machine.

Any of the versions between 15.7 and 15.12 should WORK though - if you're still getting failing work units, you have a configuration issue somewhere or your card might be dying.

To back out to older drivers, you may have to do a complete uninstall of your current drivers THEN install the older ones.

Windows 10 is NOTORIOUS for "upgrading" working drivers to BROKEN newer ones - it's one of the reasons I only have one Win 10 machine (for playing DirectX 12 games on) and REFUSE to allow that broken PoS joke of an OS near any other machine I will ever own.
