i have given up on wattman and decided to go Heliox ROM mod instead.

That is starting to sound better, and better... 

Does it work under Windows 7?

yes, he managed to get the roms working for windows and also Linux.

I have used his Nano roms and its pretty good with low power.

he also has 370 and 390 rom mods.

and the latest 480, 470 rom mods is pretty good - imagine 480 doing 31.5MHs !

Links for this mod?

I have 20 cards a mix of 480 and 470.

I am doing 470mh or about 23.5 mh on average.

I am doing about 3300 watts which is okay.

The mods can do up to 31MHs.

I am interested in the 29MHs with low power, will be flashing one of my 6 x 480 Rig soon.

It is the driver version that caused my regression in hash rate.  I reinstalled Crimson 16.7.2, and had to roll back driver version in the Device Manager.

I had to go back to 16.200.135.1001 (as reported in Device Manager) in order to get back to 26 Mh/s.

Edit:

Hmm... seems to be a mixed bag, though.  With this version of the WattMan software, the voltage and frequency settings for the core are 'N/A'.

I tend to agree with this statement. 


Yes!

However, I finally had a marginal success with it last night.  I set the memory voltage down to 0.870mV and bumped the frequency up to 2150MHz.  Dropping the voltage gave me some margin on power, and the increased memory throughput raised the hash rate from 24.5 MH/s up to 25.8 - 26.3 MH/s.  A little victory, I'll take it.

Just tried - my speed dropped from 22.4 to 19.6, so I reset to original values

As far as ETH mining is concerned high hash and low power, is the magic equation.

Now that I've upgraded to 16.8.2, I don't get any benefit from the setting I laid out below, too  Sad

I'll revert back to 16.7.2 and see if I can get back the extra hashrate.

Please let us know on your settings and minig results

Your core clock must have went up instead. What is your power reduction set to? Mine is -25%

Actually nothing works inside of Wattman with mine drivers 16.8.2

I can set any Power values and after pressing Apply they just went to stock "0"

I gave up with with shitty "powerful GPU tool" and left with stock value. Pity - but at least getting 22.4MHs ETH and 460MHs SIA with it

Wattman is total crap - only 2 parameters are available and they do not affect on mining at all

Wattman is just a huge power equation.  If you drop the voltage, it just tries to raise the core clock rate up to utilize the extra margin.  Hashing needs increased memory bandwidth, though, not core bandwidth.  Ethash is memory-bound.

I would love to try out the Polaris Editor and tweak things manually, rather than have Wattman figure things out, but I'm almost positive that means moving over to Linux because the ROM won't be signed.

If anyone could confirm or refute this last claim, I'd be happy either way!

What is your memory on the cards 4gb or 8 gb..

The best way to overclock is use Amd wattman in the Amd settings.

Are you using  16.7.2 with the rx 480s

These cards are 8Gb

Wattman is total crap - only 2 parameters are available and they do not affect on mining at all

I'm using last drivers 16.8.2

The idea on MODs is quite interesting - but I also have 3x R9 390 cards - so I dont want to mess with BIOS now

Also mod does not work well with dual mining, and looking how ETH/ETC is going down having a back up is crucial

Have you ever tried modifying the ROM?  I've been reading more and more about it, but it seems as though they'll only run on linux because it won't be signed.  Is that correct?

'The right to privacy matters'
To all,

I'm mining with two RX 480 1288MHz cards

In dual mining I'm getting ~22.5MHs on ETH and ~420 on SIA

Is it OK? Am I right that there is no good way to overclock these cards (smth like MSI AfterBurner)?

Phil,

I actually did smth like you wrote by trial and error method.

Also first card should be in a big PCI slot. And then every other should be added one-by-one

And on the fifth card I applied mod to Win 7 to have a 5 cards

So I finally mining with 5 cards

Thank you!

Which chipset is on your motherboard?  I read something earlier that the Z170 motherboards cannot support more than 4 GPUs.  I'll see if I can find it and add the link to this post.

Edit:

https://bitcointalksearch.org/topic/6-gpu-rig6-gpu-detectedonly-3-working-other-3-drivers-having-code-12-issues-1592305

Here is MB I'm using:

ASRock Motherboard ATX DDR3 1066 LGA 1150 H81 PRO BTC

So from 4pm till 4.30am I tried:

1) Remove all drivers. Reinstall them
2) Clean Win 7 Pro installation

Achieve:

1) I could run 3 cards - 2 RX 480 and 1 R9 390

Any attempt to plug 4th card results in black screen before passing BIOS post

So now I even not sure that I can come back to my original 4 r9 390

Help is needed!



Yeah mixing the 390 with the 480 has issues

Pull the Amd driver put in two 390 and no other gpu

Then load Amd 15.12

Boot it see if two 390 show up if they do
Shut down add third 390
Boot twice third should show if third one shows

Shut down add fourth 390
Boot twice and all 390 show

I hope. This helps.



Back to me I added two more gpus.

I am at 20 gpus

Two four card rigs
Six two card rigs

Would you mind telling that which motherboard are you using to place all 4 RX 480 on it? I'd definitely like to know that how much watts PSU you're using with it and what's your room temperature as well.

I am using the same motherboard that Phil mentions on post 1 of this thread.  Post 1 also links to our older thread that has alot of other information, too.
https://bitcointalksearch.org/topic/m.15913928

I personally use an 850W EVGA G2 for my 4 card rig, and a Thermaltake 750W for my 3 card rig (soon to be 4 card).  According to my Kill-A-Watt meter, the 4 card rig uses between 600W and 650, depending on settings.
