with original bat file i make 25.5 MH but when i put your bat pc freez

This is original bios
https://mega.nz/#!nDZXEQga!DfBbtP2uY9T-6N8Q1gF4KWQJATXAj29e4w2l0IsoS_g
The card is RX470 but in gpuz and msi afterburn see that is 570 Huh

ASUS MINING-RX470-4G-LED with elpida memory
Can anyone share the modded BIOS

Not sure what cards you are using, core and power settings vary between AMD and Nvidia, but for memclock you would definitely put:

globalmem 2000

Though I've found that varies too, for my cards it seems to be more effective to use full values for AMD and + or - for Nvidia, so if your base memory clock is, say, 1600, you would put:

globalmem +400

You can also break it down card to card, which is what the sample format shows, but I only do that if I have cards with different memory types in the rig, the variation isn't worth the trial and error for me (ymmv).

As far as power limiting goes, though, I can't give you specifics but for AMD you would play more with the core/globalcore setting, for Nvidia the globalpowertune. For ethash (Ethereum and similar coins), I have my 1060s (Nvidia) set like this:

globalmem +450                                                                                                                                          
globalpowertune 75

Which, on my Samsung memory cards, gives me about 22mh/s and 75W power draw.

For my 580s (AMD), my settings are:

globalcore 1200                                                                                                                                        
globalmem 2200                                                                                                                                          
globalpowertune 2

Which gives me about 28mh/s and rough estimate of 115W per card (harder to figure out because the dashboard only reports voltage for AMD).

These settings will MOST LIKELY NOT be optimal for your cards, but they are a place to start if you need one (though I suggest starting lower for memory, higher for power settings and doing some testing). Subsequently you can figure out your card's optimal settings using tools in windows and then use them as a starting point, and back off a little if there is any instability. Good luck!

EDIT: Also note that you will want to play with these settings if you switch algos, as each algo demands are different.

I mean your Over Clock setting and it's has been shown in your screenshot.

4 GB Polaris cards stable on 28,xx MHs it's good enough. Stable more important than raising your Hashrate.

Yes

Use the settings in your claymore stub in windows in your ethos config file instead.

Best best is tweaking your memory in intervals of 5mhz until your find the optimum! all the best.

Solving by yourself, Good job!
Report it again after 6-12 hours running and don't forget to share its tune-up setting! That was how a forum works.

Right now 09/02/2018 with sky high difficulty, claymore 10.0 or 11.0 i got with ASUS rx 470 4gb Mining Edition (one click bios mod , fixed drivers only amd vga drivers no other crap, windows 7 64 bit) 29.5 - 29mh/s stable, 0 errors . - GPU 1150, MEM 2100 (on some 2090,2050,2070 ...)  memvdc - 850mv gpu vdc -69, fans 40-48%, gpu takes 44 watt.  . You can get 30 mh with gpu 1250 but not worth it i see power consumption increasing too much.

Does anyone have moded bios for p104 to get 39mghs , mine cant get over 30

kartları yeni aldınız sanırım nerden ve kaça aldınız hocam burdan açıklamak istemezseniz özel mesaj ilede söyleyebilirsiniz.

Aşama aşama 764 ten itibaren -20 şekilde düşür hatan durana kadar sadece memory clock'u düşür.
