The network tries to produce one block per 10 minutes. It does this by automatically adjusting how difficult it is to produce blocks.

Damn, that's one more thing to test!
So...flash all your cards with the aggressive timings (from 1500 MHz) and identify the ones that aren't stale, then reflash those with a more conservative BIOS?

In my experience with RX 480/580 and 570's, cards with Hynix and Micron memory are stable with the 1500 MHz straps. With Samsung cards you need to use the 1750 MHz.

Can we trust "one click timing patch" ? I have sapphire 570 8gb micron. And I saw it copied the strap from 1750 and applied it to 1500 and above to 2000.

I did, I don't regret it. There's a topic here with my 580s doing 32 MH/s on ETH.

Hi,
First time using the PBE, attempting to flash an RX 480 4G with Hynix VRAM, it was doing 22 MH/s stock with compute mode,
I flashed it using the one click button BIOS and it was then doing 17 MH/s, but after restart the BIOS was also no longer detected by AMD settings, I was trying to check if it was in compute mode at 17MH/s.. but even GPUZ had trouble identifying the card, ATI Flash simply labeled it has "Polaris", I reverted back to stock BIOS after that, but I really think 22 MH/s is low for a 480, any suggestions? Also, when I use afterburner I cannot do anything above stock or the hashrate falls, this indicates VRAM errors correct?
I did a clean install and installed the pixel clock etc etc, what am I doing wrong here?
Thanks!

Step by step: - flash bios - remove drivers with DDU - restart PC - install AMD driver (august 23rd 2017 blockchain driver if you want to mine ETH) - use pixel clock patcher - restart PC
Should be ok.
Use MSI afterburner to overclock your memory & undervolt the GPU core.

use pixel clock patcher It sounds like @Alwaysdagon didn't do that. I'd keep the last Adrenalin drivers in compute mode and use OverdriveNTool to o/c.

Yes. It's pretty much what's available for free. More or less (few exception case) the one patch does these Samsung : 777000000000000022CC1C00AD615C41C0590E152ECC8608006007000B031420FA8900A00300000 010122F3FBA354019 Samsung not so aggressive 777000000000000022CC1C00AD615B41C0570E152DCB7409006007000B031420FA8900A00300000 010123A46DB354019 Micron: 777000000000000022AA1C0073626C41B0551016BA0D260B006AE60004061420EA8940AA0300000 01914292EB22E3B16 Elpida: 777000000000000022AA1C00315A5B36A0550F15B68C1506004082007C041420CA8980A9020004C 01712262B612B3715 Hynix (only H5GC4H24AJ): 999000000000000022559D0010DE5B4480551312B74C450A00400600750414206A8900A00200312 010112D34A42A3816 Hynix (only H5GQ8H24MJ, H5GC8H24MJ): 777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17

Different memory controller timings for the vram (different parameters). (wait) Clock cycles I believe.
for example on the first samsung strap tRCD Write 13, tRCD Read 24, tCAS Latency 21, etc.
There are more, above is just an sample out of all.

I used the 1.6.7 and it bricked my rx 460. Now I cant even reflashed it coz it wont detect the card anymore. I just figured out that bios editor copied the 1600 straps and even put it on 1500 which I believe that screwed it. Now I need help on reviving my card. Lenovo rx 460 4gb (micron)

It copied 1750 strap and copied it to 1500 on mine.. no problem.

It copied 1750 strap and copied it to 1500 on mine.. no problem. PBE 'one click timing patch' dosen't copy straps. That's the wrong way to do a Bios mod. PBE replaces the timings with it's own bundled performance straps. In most cases the bundled straps should work.

On my micron it copied timing from 1750 and applied it to 1500 and above.
Or have I been doing it wrong? It looked like it copied the 1750 strap (I think it was a message saying so).
