Thank you! I will try to flash the bios again now. Also when flashing the bios I'm just copying the timings that in are 2000 and pasting them in 1900, 1750, 1625 and 1500 right?
I know copying the 1750 strap to the 2000 on the 8GB 480 RX with Samsung memory works best. That's what my Asus Strix cards use. It really depends on the type of card and memory you have so you need to research what works best.

Do i copy the full timings?

In polaris bios editor you copy the entire value of the memory timing you want to use and replace the value in the higher frequency box/boxes so they are the same as the strp you copied.

So would I be copying the strap timing from 1500 and pasting it in to the higher frequency box/boxes above?

As I said, it depends on your card and the type of memory it uses.

Sounds like a driver signing issue. You need to use the pixel patcher to bypass the signature check any time you install the AMD drivers in Windows with a modded bios.

If you are using them in ethOS, you don't need to patch the driver.

Hey guys,

So I've been trying to flash the bios on my cards but I can't seem to find anything that works. I've modded the bois by copying the timings from 1500-2000 and when I reboot my computer the GPU isn't recognized anymore. I'm flashing the cards on win10 but will be using them to mine on EthOS. The cards are this https://www.newegg.ca/Product/Product.aspx?Item=N82E16814137050 and have Samsung memory.

If there is anymore information I can give anyone just ask.

Thank you
