Topic: BIOS Mod R9 380? Why so difficult (Read 471 times)
My Sapphire R9 380 mines dual expanse/sia at 22MH/s for EXP and 220MH/s SIA, at 980/1550 clocks
be verry patient and carefull with flashing gpu firmware , i have killed 2 460 , of course they arent as good as the 380 but they are alos good to test some things.
thanks
thanks
20 is probably the fastest those old Tongas will get these days. I was able to mod my 380s but ended up selling them. Nerdralph has a good post here: http://nerdralph.blogspot.com/2016/09/advanced-tonga-bios-editing.html
This card can be a useful card in the hands of the right owner. This card is basically unmoddable with my meager skills, but as compensation, it has the best cooling of any R9 380 IMHO.
1) If you are mining for fun, as the last poster pointed out, 800/1500 is the operating point of lowest power consumption for ETH coins.
2) If financial gain is a factor, then goto What-to-mine. You will find from What-to-mine that XMR or ZEC are the way to go. Both coins use even less power than mining ETH. For this card, I mine XMR using Claymore and setting A=4. Both coins have multiple choices for mining software.
3) Use MSI AB to setup the card.
Extra credit:
1) I have not moved beyond the above settings in any miner that runs this card. xmr-stak-amd has some extra parameters to fool around with.
2) After you mess around with this card running say XMR, see if you can use your CPU to also mine XMR.

I modded r9 380 bios while back but results were merely visible as it wen from 21mhs to 21.5 ...
This was typical straps copy paste.
Run cards at 800/1500 and you should get better hash rate at very low power consumption. Remeber to use blockchain drivers.

So give up then, don't do it.
I want to run my ASUS Strix R9 380 with 1020/1620 clock settings (giving me 19,99 MH/s ETH only from 18,9 stock) like I tested with afterburner but it seems impossible? Hex Editor tutorials are not helping... Can't I just set the timings in tonga bios editor and save? I don't want to brick my card though, this one has no dual bios.
