It was the memclock - it was stuck, somehow. She does over 25MH/s now, not bad.

It wasn't meant to be - I'm not against sharing instructions/knowledge, just premade solutions. It wasn't a dig at you at all.

EDIT: Btw, 02 isn't always Hynix.

So very true.. This rom can still fuck up a lot of cards..

I already shared something like this a while ago.. You can check that one out and perhaps make yours even better Smiley


Ps. Read this
http://forum.ethereum.org/discussion/comment/60221/#Comment_60221

And read the replies as well!



I had actually looked at the 380nitro ROM you posted a while back, but it had slower timing than the one I made.


I got some of those... 380X nitro - could somebody point me to the right ROM or tell me which RAM they use? Thanks!

just use gpu z. you can see ram type in it.

The results in this R9 380 hot rodding thread are somewhat incomplete in that corresponding changes in power draw with mod's would also be of interest.
In my blog post the link includes 2 modded BIOS files with DPM 5, 6 & 7 under-volted: 380NR1100.ROM and 380NR1150.ROM

How much have you gotten out of those? I've passed 25MH/s with custom timings, but at that point it needs a little more on the core for it to keep up.

I've only been able to get 25Mh by pushing the memory over 1700, which hasn't been stable on any of my cards.  I did try a couple custom tweaks (modifying individual values in the straps), but gave up after testing a couple values.  If you're willing to share the strap decoding utility, then I could create custom straps based on what timings I know are important.

I've found which are important simply by modifying all of them to some degree and checking hashrates. I'm still writing the decoding utility, so I wouldn't share it now even were I going to, until I figure out the rest.

EDIT: Once CAS latency is relaxed, many cards seem to be okay with 1700+.

Hi forum,

Thank you very much for your kindness with sharing ROM's.  Much appreciated.  I'm assuming the 380NR1150.ROM would be fine for both brands and types of 380's I have.  I just wanted to make sure before I have a go with it.

I have the PowerColor PCS+ Radeon R9 380 4GB and the ASUS STRIX Radeon R9 380 4GB.  Which see:  http://imgur.com/a/v0WXU

Can someone tell me which one of the three (3) R9 380 ROM's to use for these two cards?

The choices are:

#1 - 380NR.ROM
#2 - 380NR1100.ROM
#3 - 380NR1150.ROM

Thanks,

David

David, I have the same PowerColor card and am doing 24.7MH/s with it by using +10 power, 1023 Core clock and 1750 Memclock. I am looking for a bios mod that will get me over 25MH/s but also reduce power consumption if possible. My bios is stock on my card as well and I am using drivers 16.12.1 for it.

So for anyone wanting to know how I achieved 24.7MH/s on the PowerColor PCS+ 4GB R9 380, STOCK BIOS. I used the above config but using MSI Afterburner I unlocked the voltage in the settings and set the drop down to 3rd party. MSI Afterburner reset and then it jumped from 22.5MH/s to 24.7MH/s.

Using this same settings on a modded bios 1023/1750 +10 it gives me 25.3 on my Powercolor r9 380x. Its only been about 10 mins but seems stable at this point. Im not sure how much power is being used but im sure its a lot more than my 900/1550 -25 setting Tongue

I wonder if there is a BIOS mod out there to enable higher mem clocks than the 1750. Mine seems to handle it like a champ but wonder if it can be pushed a bit harder...

Not sure i want to push mine any harder. Probably gonna put mine back like it was before. I cant imagine the earnings are any much better and thats a lot of overclock.

I saw a post awhile back but can't seem to find it where they were getting 25MH/s with this same card and only pulling 150W. Would love to get a hold of that BIOS...

Hi there,

I used atiflash to backup my BIOS and modded it as suggested in post 21 by replacing the timing parts.
After I flashed it back and did a reboot (hardware manger said I need one, so I guess flashing succeeded) nothing changed.

I still only see 18 MH/s average. I use genoil eth miner.

I also tried the ROMs in post 1 but no change there either.

This is my Card:

hi guys!

i have option to exchange 280 to 380 4gb.
what watts will be for this custom bios change?

is it worth it 250w for 24 m.h?

thanks

Did you ever figure out what to use on your ASUS Strix Radeon R9 380 4Gb card?   What did you do to it and what are you getting now?

Hallo

I am currently now a newbie.. not a good timing eh while the market crash...
Anyway i am looking forward future and enjoy learning the process...
Currently i own several 380 and 380x...
I do try to flash them all with the bios, but cannot seems hit 22 or 23...stuck at 19-20...
So far after i flash them with 380NR rom i change ram to 1625 and gpu to 980-1000 and see no noticeable change..
What mistake i done ?
Using win10 and radeon 16.2 and genoil 9...
