1150/975 1950/900

[tadeus1]

May be try with this one  samsung 3.2. its not that tight.
TRCDW=14 TRCDWA=14 TRCDR=25 TRCDRA=25, CL 21

777000000000000022CC1C00CEE55C46C0590E1532CD66090060070014051420FA8900A00300000 012123442C3353C19

or

copy your original bios 1500 strap to 2000. This would work too.

p.s. I see no real need to undervolt the mem to 900 since your core volt is not that low. you can keep the mem at 1000.

Want to use less power

Thanks. Tried that yesterday. Only got 28.x hash.
Micron gives me 30.9

[tadeus1]

for less power you could undervolt the core to may be 900.
for even less power, core speed to 1075-1100 and undervolt to 850-875 but then the hashrate would drop also. you have to experiment to see which sweet spot you like.

Mine now are kept at core 1100/880 mv   mem 2000/1000mv - around 29 mh for eth.  aprox 110 watt from the wall. I can get to 31 mh, but don`t like the electricity usage at that level.

Thanks. Will try those settings with ubermix 3.1 tomorrow.

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)

1. Unplug the bricked card.
2. Use DDU to delete the amd drivers in safe mode.
3. After a restart windows installs the Microsoft standard drivers.
4. Turn off and plug the bricked card.
5. Now, if you are lucky, you can flash an other BIOS to the card.

I flashed wrong bios on mine yesterday. Lol.

1. Ddu in safe mode
2. Restart
3. Use atiwinflash and flash original bios
4. Restart
5. Flash correct modded bios
6. Restart
7. Use pixel patcher

I use internal gpu

[Chromey85]

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.

Hi,

Now, I've done this on my strix rx570 4GB and the first time i got 30 + 22 + 22 mhs on claymore 11.6 mining ETH, then when i tried to get the second card to hit 30mhs, its dropped down to 18mhs and the same with the 3rd.

Now do i need to remove drivers first then follow the steps above for EACH card? i.e start as if there are no drivers installed or start with the standard drivers installed and then follow the steps?

Also is it best to undo the pixel patch and redo with every card or pixel clock patch all at once?

Many thanks in advance

do you have a great timing for hynix and micron?

Am I the only one having trouble accessing jaschaknack's github page?

Does anyone have a copy of the 1.6.2 PBE, and is willing to upload it?

Thanks!

[qwick745]

I haven't been able to get the PBE one click from jaschaknack's github either, keep getting 404's not found for everything under his user.  Definitely could really use someone to provide a mirror please.

[Vann]

Not sure what happened with jaschaknack Github. PBE works great for me. Here is PBE 1.6.2 through 1.6.7 I uploaded.

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

Anyone have GOOD for samsung?

For my Strix RX480 8Gb (Samsung memory) used PBE 1.6.7 "One click timing patch". Timings are identical to Uber 3.1. My card is stable with this modification and without further additional settings gives 29.3 MH/s.

This is great. In my new miners I am about to setup for my colleagues I did the mistake of not saving a copy of the Polaris 1.6.7 which is the one which works great with any Sapphire card for me so far, 570/580 and they work great with specific mining computer boards like Biostar and Asrock.

I don't know why many people are saying that the 1.6.7 is way too unstable as I have not encountered any error with it and the Blockchain August drivers in the rigs I manage for my friends, but maybe I have just been lucky which I don't believe.

My configuration is the same, 1 click timing BIOS mod of every single card before putting them back together as 6 and then applying Pixel Patcher. I don't overclock much through MSI, usually I leave Rx 580 at the 2000 memory clock and only undervolt the core clock. With Rx 570 I increase through MSI, from 1750-2000 and they run stable. I am talking about 4 Gb cards here.
