I only get 24 sol/s with stock bios i see some ppl reporting 30 Sol/s or higher with rx 480 i assume because of modded memory straps.

Anyone know why the gpu voltages are not in actual mV? Is it safe to just enter a value in mV? This is Mis rx 480 4gb btw, thanks!

You can enter mV values but they will be ignored. GPU core voltage is calculated at runtime in relative steps to its base voltage. What you will need is an offset either hardcoded into the bios using a hex editor ( complicated ) or a tool like Strixx or Watttool ( simple ) to load the core voltage offset at system startup.

I have just started using watttool to adjust voltages, in regards to the memory i should copy the timings from 1750 strap across to the 2000mhz strap and flash that?

That is right. That is what most people do. But for the ZCash mining, it is better to use the stock bios.

For mining you'll find they're identical with identically modified BIOS. Get whichever is cheapest IMO.

Fail to plan, and you plan to fail.

So you have card bios with timings same from 800 all the way up AND IT IS WORKING?
Yes, you can put voltages...

You know that's not possible. Its probably just the first half of the Straps that are the same/similar.

Hello.
I have Sapphire RX 480 Nitro+ 8G, default 1342 MHz / 1150 mV maximum.
I changed DPM table in PBE at -75mV. After flashing bios, voltage settings was default (stock, not changed). Why?
The new settings was applied only after pressing Reset button in MSI Afterburner or Trixx.
Then if I play with voltage in Trixx, card may be crashed. And after rebooting voltage is default (stock) again!! Why?? What should I do to voltage were always the ones that I setup in DPM?

why... if change anything in polaris bios and update bios on my sapphire 4gb, it not working, no picture nothing?
even if change only 1mhz in the memmory.
even if manualy put back on stock settings, not working, i must flash with stock (backup) file/bios...

why???


Update
i open original (backup file) in polaris editor 1.4
just open and save... flash saved bios... not working

like, polaris bios "destroj" the file.

what is going on?

it is possible to get some link, for bios for, sapphire nitro+ oc 4Gb for 30-+mhs ?
Please.


elpida?

If you find the right memory strap for your elpida, it is possible to get that GPU to have 30+ MH/s rate.
