Polaris BIOS editor

[Amstellodamois]

Which one is the right one? The original or the one which works with most cards?

I see we're at v1.4 on most GitHub versions:
https://github.com/caa82437/PolarisBiosEditor

But this article mentions 1.6.7 and I found its GitHub.


There even is a paid supposedly v2 mentioned here: https://bitcointalk.org/index.php?topic=1954245.0




So, which should work?
I have 5 Saphire Pulse RX 580 8G and 2 Aorus whathever (580 - 8G as well).

I like jaschaknack's version. I've had very good results using the v1.62 'one click timing patch' on the original Bios. PBE automatically detects the memory type and v1.6.2 applies the bundled performance straps to the 1750 MHz and up timings. The current v1.6.7 adjusts the 1500 MHz and up timings, but the 1750 MHz straps are more stable for most cards.

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.

here is the site for that paid for one you mentioned

Well, I didn't want to advertise it 😁

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.

[Amstellodamois]

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!

[Iamtutut]

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.

[Amstellodamois]

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

What do these correspond to?
Microseconds?

[tadeus1]

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)

[Amstellodamois]

Thanks @tadeus1

Sorry for your trouble, @solidgang

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.

[Bigdrago]

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).

[Bigdrago]

Samsung ubermix 3.1 is way to unstable.
GOOD micron is working fine.

Anyone have GOOD for samsung?
