I am trying to port this over to Windows for everybody.
Is there any tips you might have besides making use of the PCUtil's app?
I've not programmed in a long while so this is a bit out of my wheelhouse but somebody should step up.. well i'm that sucker.

Thank you! Any help is greatly appreciated. The fact you got this working on Linux and how fast the many mining OS's are implementing this, is great. I only wish i could do this conversion to Windows faster.

Thank you for this beautiful code.

Yes. Linux provides the mechanisms to work with MMIO, physical memory etc, but windows exposes no such API or method. So you need a kernel mode driver to work with physical memory. On top of that you need to self-sign it, or disable Driver Signature Enforcement for said driver to work. Or pay $100 or so to sign it legitimately.

ElioVP, since you are sort of the local AMD God.. You have any solid ideas on how to get R9 Furys jiving with TeamRedMiner?

The readme states "./amdmemtool --RFC 43 --ras2ras 176" in the example for GDDR5.

Is that the optimal settings for a 580?

Also, "amdmemtweak" works for me not "amdmemtool." Am I missing something?

Since you are advertising *paid* solution at least have the decency to *donate* to the developers!

I've made 20 posts here since July 23, 2015, does it look like I'm a spamer?
I'm just trying to share with others. Thanks for encouraging conversation!
I'm just a happy minerstat customer, no finacial involvement.

He is not advertising. bbrodka is our paying customer and is having no benefit of posting this. However, we have talked in private and he genuinely missed J's previous posts.

AMD Memory Tweak is open and free to use for everyone and can be used also from a dashboard and not just from the console.

Also, need to thank Eliovp as he's been very supportive during the implementation period. Once we are ready with our Timing Database, we'll give back and contribute further to the community.

Seems it's not so relevant for RX series compared to vega's.

It's relevant, it's just that we already had a way to update timings for polaris, via bios flash.  But 'live' timing updates are still quite valuable.

Holy shit, that's nice man.
Is it stable? Is this ubuntu or you use hiveos/minerstat/similar?

Ubuntu 18.04.2 LTS and AMD-gpu-pro 18.50

Still struggling with 4.15 kernel not able to set clocks properly.
Anything above 1700MHz in P7 state puts the GPU in crimp mode. So I have to use 1700/1030mV in P7 to get the highest possible coreclk. Ideal would be something like 1800/975mV in P7, that would make ~1650 effective clock in P7 at much lower wattage
I learned I will have to upgrade kernel, but don't know which version, there are also complains everywhere about 4.17-4.20 all over the forums.

I'm currently testing stability.

Wondering what would be the eth hashrate with these timings.
Implying on CN algos it gives +15%, 45mh*1.15=51.75mh
Gonna test it later.

I get a little over ~1800 on srbminer 1.8.0 win10 at 880 mem and 900mV - Hynix memory is extremely unstable in my experience. GL man and cant wait to read your update.

could you share your values? and also is your vega 56 flashed to the vega 64 bios or stock?

Basically started with your settings and then added some more.
I'd like to enjoy the race a bit longer so I don't share it directly but I give you a hint: you can find some simple formulas quiet easily that help calculating the numbers.  Cool

Vega 64 bios, yes.

Dear god man... forget about the kernels and dial that thing down.  I get this is a dick measuring contest, but you’re prob running 225-250w for that 2100h/s, or about 80-100w more than you would need for 2000, without timing mods (I got 2K @ 837mv.)  +50% power for +5% h/r is not worth it - even if your power is free!

Hi,

We tested Vegas were the most stable with 18.50 driver + 4.16 kernel.
4.17 and upper had problems with stability and most of the times the GPUs were undetected. (clinfo)

https://github.com/minerstat/minerstat-os/blob/master/bin/overclock_vega.sh

This script works perfectly, you can give it a try.

Code:
sudo ./overclock_vega.sh 0 945 1100 80 950
