Thanks for sharing that, it's helped the development of PolarisBiosEditor

Hi no problem here a pic from the RAM:

8gb model confirmed. The only thing i'm thinking now is that voltage. Even in wattman you have 1000mv. I think it's more some AUX voltage, like on Hawaii. Because those memory are rated 1.5v, it's on Samsung's datasheet and in general, GDDR5 range from 1.35 to 1.6v

I 've read that the 1000 mV stands for the controller not for the Ramchips

BIOS flash is working now: https://www.techpowerup.com/223913/amd-retail-radeon-rx-480-4gb-to-8gb-memory-unlock-mod-works-we-benchmarked
Just flashed the 8GB on my 4GB card and started this tool d3dglvramtest two times:

So are we still waiting for a bios flash tool or does one exist? I'm looking to tighten timings and increase max mem speed.

BIOS flash is available now: techpowerup

Tested the 8GB BIOS on my 4GB card and started this vram testing tool two times:

Wow thats great i´m downloading Atiflash and the polaris Bios Editor now

but are there any instructions how to use the Polaris Bios Editor

well i gone wait intel you guys did the testing i´m a little bit scared that i could mess things up

Any programs to modify bios besides the Polaris github one Posted earlier? So with this whole vram voltage vs controller voltage... Are we only able to change one and not the other? What can we possibly max out at with these cards?

I would like to suggest those 2 tools:
1. MemoryInfo https://www.techpowerup.com/downloads/2326/asus-radeon-memoryinfo-1-005

This one can be good to see what memory modules your card has. I don't know if it works on RX 480 too (some tester? biggrin.gif)
Memory module should be: Samsung K4G80325FB-HC25. This is a 256MX32, correct me if i'm wrong.

2. VMT, video memory stress test https://sourceforge.net/projects/vmst/
This one shows you both the amount of VRAM you have and stress test is. It's like memtest86. It won't need OS, just burn it on a USB stick and you're golden
