Okay daft question, is modding a bios any better than say using afterburner or trixx?

Would it be best to find the best settings using say trixx before modding the bios?

You don't understand the bios thing. You can always set clocks, TDP, voltages,... but the best improvement you can have only with performance timings like Uber-mix, that can be changed only in bios. You can also set voltages, etc in the bios, it's better but not needed. After the mod you need OC the memory to find the highest stable memory clocks. When you find it you can set that in you bios, still not needed.

Aaah Ty, I was assuming the bios mod was just setting the mhz but it's actually also changing its performance timing, I guess similar to pc memory, going from say CL12 to CL9.

adjusting straps is not something that can be done real time.

custom timings and copy/pasting tighter straps up to 2000MHz clocks can only be done in bios.

if you're running linux there are limited apps like those available in windows that adjust voltage on the fly.

hard coding under-volting to bios provides advantage of it being properly volted for mining efficiency every boot up.

over clocking memory and core for the most part can be done via software after booting to os but why bother if you have tested and found the sweet spot it's best to hard code it into the gpu bios.

Thank you for your reply, it is more the timings for memory that I will try to begin with but first test the other settings using Afterburner.

Hopefully mod my first bios next week on one of my asus strix rx480 cards.

First post! Grin

Can anyone please help?

My first post too. I've just trying to flash my Asus rx 580 dual 8gb on Samsung memory. None of straps from overclocking theme worked as I wish because of huge amount of errors in HWInfo

In stock it was 22 mh on ethereum and 800 on decred. And now it is 27 mh on ethereum and 1100 on decred.

I can't overclock memory because ethereum mh decreased at the moment.

The question is - if there any working strap for this cards with 28-29 mh?

What are your memory clocks? To get more you need to OC memory.

A complete newbie to mining. Just setup my rig last night which consist of:

Windows 10 x64
Claymore 9.4

Asus B250H board
Intel G4400
750w 80+ Gold
120gb ssd
4gb ddr4
2x Asus OC Dual RX580 8gb

Just that for now as i'm waiting for my risers - then i'll be able to add my 3x other RX580s.

Anyway, tried modding my BIOS using the instructions on Post #1, followed everything by the letter then after restarting, fired up Claymore then curiously got 4MH/s each card (instead of the default 25MH/s out-of-the-box). So i'm pretty confused here. My GPU has a Samsung memory.

This is the BIOS that I modded using Polaris BIOS editor:

Can anyone please help?

Did you reinstall drivers and apply patch? Edited right timing straps?

Hi Matt, just one more question came to mine, I also have a 4gb rx480, can the memory on that be pretty much tweaked to 8gb speeds or will a 4gb rx480 card always offer less MH/s mining power than a 8gb card? Even if both cards where identical other than the amount of GBs

If you tweak 4GB and 8GB for ETH the 8GB will be probably better, but if you mod the bios for 4GB it will be much better than 8GB stock.

Perfect Ty, out of interest, would the memory speed change affect gaming in anyway? Or add extra heat / power draw.

Yes, the bandwith will be higher that means more FPS. Power and heat are about the same if you do not undervolt.

for some reason after i force flashed a nitro plus bios (anoraks) to my nitro non plus rx 480, i can now oc the memory to 2050mhz stable wherein my stock bios i can only go for 1850mhz OC otherwise it will crash.this somehow increased my hash rate to 22 to 29.can someone explain to me whats happening here.
