Please, if possible, I would like two versions of BIOS:
- powersave

I’m building 2 rigs with 6 cards (total 12 card this model).

Thank you!

In the BIOS you provided, there are two sets of timings.
Here is the confirmation:
Try to use these timings:
Elpida 777000000000000022AA1C00AC615B3CA0550F142C8C1506006004007C041420CA8980A9020004C 01712262B612B3715
Hynix 777000000000000022C39C00AC595A3D90550F12B84C8408004006007E0514206A8900A00200312 0100F292F94273116
Frequencies 1167(cclock)/1940-2070(mclock)
Do not forget to change them in WattTool or Overdrive.

Try a different version of polaris. The last one 1.6.6 even have an auto feature. Worked great for me, with elpida memory.

Thank you.

Also, what clocks are you using?
I'm on 1150 core and 2050 mem. Can I squize more?

Basicaly in 1.6.6 I just click down left and save and thats it?

What about voltage - how can I make it more power friendly?

That's it for polaris. Simple enough !

I have nitro+, not pulse, so might be little different. I use 1130 / 2080, 30,3 eth / 910 decred. It was getting very unstable over 2100.
Seems like I can't go under 925mV for voltage. I've read that you can decrease voltage more with pulse, not sure though.

Just use wattman / triXX / afterburner to tweak, and when you have a sweet spot, you can go back to polaris to make the change permanent.

But how do I undervolt? Itried -100 in msi afterburner but power concuption is still high, or am I wrong?

How do I undervolt directly in polaris editor without having to change voltage in afterburner?

Thank you sir!

Can you pls share what modifications have you done?

^^^ straps,  voltage & frequency adjustment.


IIRC I had some problem with this card, I got it as is and I think I underclocked it to compensate for a fried VRM. It possible all pulse cards are like this too. In any case this is the rom I've got running in my card, I think it's the slowest card I own.
