Modded r9 380 4gb and r9 380x, for all gpu brands that have elpida memory.
Tested and tuned, so all you have to do is flash it and mine.
(Gpus with hynix ram, could also be fine tuned, pm me for details)
Proof:
Modded version:
https://s31.postimg.org/8t54rb21n/Screen_Shot_2016_07_19_at_19_40_26.pngThis mod will give you a rough 10-15% increase in performance. 21-22 MH/s (stock) vs ~25 MH/s (Modded).
While consuming ~150w from the wall.
Currently, only available for r9 380 4gb and 380x.
Price: Available upon request.

4 clicks, and your card is mining much faster.
What chips on your overclocked at 1750 cards ?
Without modding it, you will get 21-22mh.
@bitcanuck does this require anything other than setting the numbers? are you overvolting somehow? Also have you tried this with underclocked core? I have my MSI gaming 380s set to core 800 mem 1500 and they hash about the same as stock core but at much lower power.
1750 mem is to high for 95% of the cards.
As @bitcanuck said, he raised his mem to 1750 and gets that same hash rate.
There is no rom mod needed to get that..
+ asking money for something that can be done without any modifications to the rom.. Funny
Perhaps.. the only thing that isn't possible on tonga is to raise the memory voltage
You can only raise the voltage given to the controller which gives the memory it's voltage
Anyhow, just tried it, raising mem to 1750, runs fine yeah, but i'm sure it will crash after a few hours..
I'll be doing a mod for 380 later this week, (timings), for free! <-- yeah!
Greetings!
But true none the less!
Those Tonga's are quite interesting though.
Will do A LOT of more testing on these, as well as bios mods. "definitely!"
Greetings!
Results are clear enough.
Stock, hashrate sometimes avarages down to 10Mh as you can see in the picture
Now with tighter timings, speed is basically the same at the same clocks but avarage goes up by a mile, as you can see for yourself.
So no rediculous high clocks, just pure timing edits
If interested, let me know
Ps. no claymore as well
I you want to talk to each other, please go to a different place.
Thnx.
Tried with 800-810, wasn't any better.. also tried to raise it to 1750, speed was 23.5.. yeah.. obviously..
but again, card won't hold it..
@aili
Free world, free speech..
+ i made my point.. mine will last for years, yours will eventually crap out.. (trust me.. been around long enough..)
WRONG it's not possible to raise your memory voltage.
You can however raise the voltage for the memory controller. But not the Memory itself.
+ didn't you tell me in pm you did something on the timings?
Greetings
I have 2 Sapphires (one with backplate with hynix vram, other older non-backplate with elpida). Both are 800/1500 with ~100mv less core voltage, hashing 21.1~. I used TongaBiosReader to do the bios changes, but I feel this program is confusing (2 voltage tables for core?) while at the same time limited, especially with the vram.
So, do I leave it be with the 21.1mh/s, or am I missing out?
and I need a modded bios for my powercolor R9380X
