But the memory controller load is usually over 90% if I set the frequency to be 1250 MHz. I think Etehreum uses a lot of memory access.
yes sir ,in fact Etehreum uses a lot of memory access

The best I could get was this
27.1MH/s using 170watts running at 950/1500 using 0.938V
So about ~ 6.3W/MHS.

So if you only mined ETH without sia it would only use 140watts ?

I also have some xfx 390 cards, and get more errors with these. I think the G1 series has bether asic quality. I made 2 mods with almost the same settings.

I've already got at least the same results: only 3 cards out of 100 don't want to work with a table mentioned in first post. What can you advise me to do with those 3 cards?

Hi Bobben 2,
thx for your detailed post. Everything is fine for our R9 390 cards in common, but we really expected some troubles in stability with only several cards out of 100+.
You've already edited bios for 380X, could you, pls., share it with us?
Thank you in advance.
Hi , I added links to modded BIOS files in the O.P. Cheers.

Here is the screen [Gigabyte 390 bios.jpg]( https://postimg.org/image/brf8wjm89/) Put Bobben's values into four "Voltage" tabs in "Limit Tables" section + into two "Voltage" tabs in "PowerPlay" section.

For my own mod, I run the R9 390 below 1000mV, but the Core/Memory is just 975/1000 MHz, so the hash rate is just 27.4 MH/s.

You can use some kind of BIOS editor to do the mod yourself. There are many instructions on the internet.
