Polaris Bios Editing ( RX5xx / RX4xx ) - Page 46

post #451 of 3354
Has anyone tested downlocking gpu and memory and measured power consumption afterwards? Also I would like to ask, what's the default voltage range with these cards.

I already asked AMD support and they said that I should contact the card manufacturer about it... I know there are some people with exactly the same issue.

My card has black screens maybe once in 1-2 hours on desktop or browsing web. But if I connect a second monitor the card goes into multidisplay mode (voltage goes 0,8V->1,0V) and it will be completely stable! Another workaround would be to fool drivers into multidisplay mode even when only a single display is connected. Is it possible? Ffs why did AMD make it so hard, I wouldn't want to use Windows test mode etc. frown.gif

RMA unfortunately. No GPU maker really allows proper and full voltage and clock control for both 2D and 3D or any other possible state. It's a shame because they really do mess up the states by default and enthusiasts can tune it much better than the cheap workforce of AIBs.

Just out of curiosity how do you enable test mode in Win8.1? I've only done it on Win7 and know it can be a PITA and the new Win made it even harder.

Will you be able to help?Polaris Bios Mod ( RX470 )?
post #459 of 3354
Hello,
i use SAPPHIRE NITRO RADEON RX 470 8G
with Ubuntu

I have tested diffrence BIOS Version:

1. the Normal Standard BIOS
24 mhs / 200 Watt (whole System)
https://dl.dropboxusercontent.com/u/46174172/Screenshots/Standard.JPG


2. the OC Standard BIOS
24 mhs / 240 Watt (whole System)
https://dl.dropboxusercontent.com/u/46174172/Screenshots/OC.JPG

3. Change Values with the Polaris Editor
24 mhs / 190 Watt (whole System)
https://dl.dropboxusercontent.com/u/46174172/Screenshots/Test1.JPG


What values ​​do I need to change so that I reduce the power and the increasing MHS??

thx lg Martin

Timings for memory.
Try 1750 how works if its same or better then copy timings from 1750 to 2000 and use 2000 for mem
