Hello!
ETHMAN.exe's source code avaliable somewhere? I want to communicate with the miner but not with a browser client that always refreshes the miners window. Is there some documentation how can i read only the json response, and how can i send commands to the miner?
Thanks!

Is AMD R9 390X faster than 390 at the same core/memory frequency?

If anyone can give some information on how to undervolt I would be very grateful.
Saphire rx470 8gb cards.
Here is what I do to get 28MHs+ on my MSI RX470 gaming X 4gb Hynix . (Find out what type of chip you have in the GPU - You do different processes for each) 1) In ATIwinflash save your base bios: Open atiwinflash and hit save. Save the file. 2) Strapping: Open Polaris Bios Editor and on the timing (MHz) copy the 1500 data to the three settings larger than 1500. On Samsung you will copy the 1750 timing to the larger values. Watch this video that shows you how to strap. I did the same method: https://youtu.be/OP_zSP2H6ho This will get you 23.5mhs per gpu. 2) On the MSI Afterburner I set the Memory Clock to 2000 and the Core Clock to 1150(up to about 1275) and press the check(Apply). This should get you the 28mhs. 3) Now I go to WattTool and look at the numbers for each gpu individually. In this case for gpu "0:Radeon (TM) RX 470 Graphics" look at the mV number in "R7" = 1150mV. I do not want this number less than 1000mV. This is just my preference. Look at the Voltage Offset. Whatever number you put in here it will be multiplied x 6.25 so, 20 x 6.25 = 125. 1150 - 125 = 1025mV(which is above 1000) so this one would be -20 and then click "Set" This gpu should now produce much lower watts. 4) Go to the next gpu and evaluate the number and make the changes in the Voltage Offset based upon the mV number in "R7." Each gpu will be different. Good Luck Let me know if you have more questions. Can I undervolt without messing around with the polaris bios editor? I am happy with the speed, just want to undervolt. Thanks for the information, I will give it a go. Yes, just start at step 3 Nice tutorial. Thanks

Running v12.4 ZEC on Win7x64 with 4 AMD cards - none show up with a GPU temp. The miner is hashing correctly, just not showing temp in Miner or Miner Manager. I have 15.2 downloaded, however the current version is 17.10
Do you think the issue is with the newer drivers?
I have the same driver on ETH v12.4 and the temp reports correctly, though it is running on Win10x64
Any ideas?
What I 've seen is that when you don't have a card connected to a monitor, the miner works although you cannot use all the AMD features (like MSI Afterburner).. Probably if you try to open AMD Radeon settings you'll see that cannot be opened due to there's any monitor connected. W10 64b ¦ AMD 17.3.1 (happened the same with previous versions..) Regards

easy way to undervolt, is just use msi afterburner. of course change the mem straps for higher speeds first though. Just look at your voltage in the monitor window, and drop that baby down as much as you can. if it crashes, no biggie, just bring it a little higher. changing the core clock will change the .states so the voltage will be different and will have to be played with again.

It is. MSI 390 @1135/1500 gives 415 H/s MSI 390X @same gives 425 H/s Both stock bios, wattage not measured.

Sorry... forgot to report back on "latest AMD drivers". Anyways, I tested your miner with my RX 460 - using the latest drivers (17.x.x) Together with dwarfpool... And whalla! it worked... I made over 0.01 zcash in one day alone (I get just over 150 sol/s)
Thanks Claymore!

Anybody tried the Biostar TB250 mobo?
I was thinking of trying it out but thought maybe you guys already had and have any advise
Thanks...
Yes I have one running a Celeron 1150. So far no problems

I have trouble with my r9 in version 12.4. You better fix it. When the next version will come out.

Is that R9 nano? You should use 16.3.2 driver. Or reduce the frequency or intensity.
