I changed BIOS with new memory settings, and OC memory to 1550MHz

I call fake news. Just modded my 380's and no where near close to 600 H/s. Pics?

Edit: in case you're real unbeliever because of just one share done, I can post another one after few hours
of hashing, or I can go back mining expanse, can I?

I had 650H/s with Nitro R9 380. I've used NerdRalph bios for that. My result is also on Monerobenchmarks.

I have 4 Nitro 380, 507 H/s is max I can get from them... I have the same bios flashed if you mean this one: https://bitcointalksearch.org/topic/custom-r9-380-bios-for-23-24mhs-1620733

Btw 560H/s on monero is low for that card, I almost get that on my RX560

In my posted pic it shows 579 H/s. Don't know where you get 560 from.

I have to check watt usage though, I think I will dail it back to powertune 6 instead of 7.

Ok, few H/s more or less, it still should be way higher imho...I checked it on my R9 380 and I get 670

monero mining uses much less power than ETH anyway, at least
on my cards

yes, same here with my r9 cards. 380X = 529 H/s, 380 = 485 H/s, 290X = 672 H/s, 290= 627 H/s. (mostly on stock settings)
What did you do to your 380 to achieve 670? Cheesy

But, if you don't have cheap/free power then the RX is a better choice.

Ok, with 1190 core and 2000 mem OC I took the 570's cards to 599-627 each:

I've updated ethos to 1.2.5 and it seems like OC is no problem now at all.

Got an extra 34 Sol per card out of it:

Temps only increased 7°C.

That is because there was some change in ATI drivers 1.7.7.2 and newer that messed up
overclocking in all tools but default wattman (until programmers caught up and patched
their OC tools)

I would take Elpida over Hynix any time.

yes of course, I have checked the compatibility of rom and card. Every card has Elpida mem. The rom I have found should be for the exact same Sapphire Nitro+ 4GB 570 Elpida version.

In Windows the OC is easy but I want to use the card in a linux rig. That's why I want to mod the bios.

Copying and pasting the straps are not doing any good either. I need to set the clock and mem settings somehow inside the bios...

I use RX 580 memory from Elpida and Hynix. Modified firmware I downloaded on the Internet. On Hynix everything went well. The rate rose from 23 to 31. But with Elpida I had problems. The long rate did not rise. I gave the GPU to my friend and he set them manually. Only after that my speed went up to 29 but the temperature of the chip at Hnike below. If there is a choice it is better to buy Pulse with memory Hynix.

Modded bios can add speed after overclocking in most cases.

Yes, in most cases, in some cases, it gets slower.

What miner are you using? Most miners will allow to OC underclock right there.

I'm using ethos with sgminer-GM but I have bad experiences with OC in ethos. Seems like it is not responding to OC-settings.

Don't download bios elswhere... it could brick your card very easily. Mod it, like bouldou post, you can use my tutorial or any other that use PBE or SRB editors, It's easiest and very safe way.
Your problem with that bios is probably 2 memory vendors in it. Your card uses the other vendor than the modded one.

Edit the original ROM. Just copying your memory straps should give you a small increase. After that you pump up your memory frequency and lower your clockrate.

the flashed bios version what you downloaded from the internet , was the same as you have it on the card originally ?
