I have read this thread and those on etherforum. But before I start testing around I would like to know what are your best results with a R9 380? I read 23-24MH/s, but how about power usage?
I got ~24.5Mh on one card that was stable at 1700Mhz, but I got lucky with that one. Typical is around 23.5Mh clocked at 885/1625. Power consumption depends on the chip leakage characteristics, and depends on how much under-volting it can take. You should see 160-180W at the wall with a 85% efficient PSU.

Edit: Forgot to mention, currently working on shedding rops, will "hopefully" have a working result by the end of this week ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) @Eliovp Any luck diabling ROPs? I'm curious how much power it would save. I never came across any info on how much of the power saving of the Stilt BIOSes was from ROP shedding vs under-volting.

For 280x we used always WolfO kernel. They works great.

Will have some more time to continue my work on this next week. how about to mod bios so 280x can give at least 20MH?
20Mh = not possible. 18+ is perfectly possible but to give a comparison. If you run at 16ish and you mod your rom to do 18+ which will give you "as an example" + 25% hash increase, your power usage will go up like 30%.. so is it worth it? Nah..

So I need to add that timing, won't that make the file larger? Can I do that? or do I have to remove something?
Basically add this
1C 19 02 00 77 71 33 20 00 00 00 00 EF 51 4A 2F 80 55 09 11 32 26 4A 04 00 6A E4 00 22 AA 1C 00 6C 02 14 20 CA 89 00 A8 02 00 07 C0 15 10 20 25 35 27 33 11
inbetween the 1250 and 1500 straps.
Replace them ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) 20 4E 00 01 33 31 33 20 00 00 00 00 61 88 11 08 D0 54 07 04 0C 07 C1 00 00 21 60 00 22 AA 1C 00 02 00 14 20 8A 88 80 A1 00 00 01 20 03 02 06 07 09 08 0D 0B 40 9C 00 01 55 51 33 20 00 00 00 00 63 10 22 10 10 55 09 09 10 0E 92 01 00 21 60 00 22 AA 1C 00 2B 01 14 20 8A 88 00 A3 00 00 01 20 05 04 0C 0D 11 0F 11 0E 80 38 01 01 55 51 33 20 00 00 00 00 E7 A4 44 20 50 55 0B 0D 1A 97 34 03 00 26 A1 00 22 AA 1C 00 4B 06 14 20 9A 88 C0 A5 00 00 01 20 0A 08 17 19 21 18 1B 11 90 5F 01 01 55 51 33 20 00 00 00 00 08 29 45 24 50 55 0C 0D 1C 18 A5 03 00 27 C1 00 22 AA 1C 00 4B 07 14 20 9A 88 80 A6 00 00 01 20 0B 09 1A 1C 25 19 1D 11 A0 86 01 01 55 51 33 20 00 00 00 00 29 AD 55 27 50 55 0C 0D 1E 99 05 04 00 28 C2 00 22 AA 1C 00 4B 08 14 20 AA 88 00 A7 00 00 01 20 0C 0A 1C 1E 28 1A 1F 11 74 B7 01 01 55 51 33 20 00 00 00 00 6B B5 66 2D 60 55 0D 0E 22 9C 96 04 00 29 E3 00 22 CC 1C 00 53 0A 14 20 BA 88 00 A8 00 00 01 20 0E 0C 20 22 2E 1D 23 12 48 E8 01 01 55 51 33 20 00 00 00 00 8C 39 67 31 70 55 0E 0F 24 1E 17 05 00 4B 04 01 22 DD 1C 00 5B 0B 14 20 4A 89 C0 A8 00 00 01 20 0F 0D 23 25 32 1F 25 13 1C 19 02 01 55 51 33 20 00 00 00 00 AD 41 78 37 80 55 0E 10 28 21 98 05 00 4C 05 01 22 FF 1C 00 63 0D 14 20 5A 89 C0 A9 00 00 01 20 11 0E 27 2A 38 22 29 14 F0 49 02 01 77 71 33 20 00 00 00 00 CE C5 88 3B 80 55 10 11 2B A3 18 06 00 4E 26 01 22 11 9D 00 6C 0E 14 20 6A 89 80 AA 00 00 01 20 12 0F 2A 2D 3C 24 2C 15 20 4E 00 00 99 91 33 20 00 00 00 00 60 88 11 07 C0 54 0A 06 0F 09 91 00 00 20 41 00 22 AA 1C 00 15 00 14 20 9A 88 40 A1 00 00 07 C0 03 01 05 07 08 0A 10 0C 40 9C 00 00 99 91 33 20 00 00 00 00 60 94 12 0F D0 54 0A 07 15 8D 32 01 00 20 41 00 22 AA 1C 00 1D 03 14 20 9A 88 80 A2 00 00 07 C0 06 01 0A 0F 10 0E 16 0C 80 38 01 00 77 71 33 20 00 00 00 00 A5 AC 35 1F 30 55 09 0C 20 98 75 02 00 44 82 00 22 AA 1C 00 44 09 14 20 2A 89 00 A5 00 00 07 C0 0C 06 14 1A 20 19 21 0F 90 5F 01 00 77 71 33 20 00 00 00 00 E7 B4 36 23 40 55 09 0D 24 9B C6 02 00 44 A2 00 22 AA 1C 00 4C 0B 14 20 2A 89 80 A5 00 00 07 C0 0E 08 16 1C 24 1C 25 0F A0 86 01 00 77 71 33 20 00 00 00 00 29 39 57 26 50 55 09 0E 26 1D 17 03 00 68 C2 00 22 AA 1C 00 54 0C 14 20 AA 89 00 A6 00 00 07 C0 0F 0A 18 1D 27 1E 27 10 48 E8 01 00 77 71 33 20 00 00 00 00 AD 49 49 2F 70 55 09 10 2D 23 E9 03 00 68 C3 00 22 AA 1C 00 64 0F 14 20 BA 89 80 A7 00 00 07 C0 13 0E 1E 23 31 24 2E 11 F0 49 02 00 77 71 33 20 00 00 00 00 31 5A 4B 2F 90 55 09 12 36 29 AB 04 00 6A E4 00 22 AA 1C 00 74 04 14 20 CA 89 00 A9 02 00 07 C0 17 12 24 29 3B 2A 37 12 C4 7A 02 00 77 71 33 20 00 00 00 00 73 62 5C 32 B0 55 09 14 3A 2D 1C 05 00 69 26 01 22 AA 1C 00 04 06 14 20 EA 89 80 A9 03 00 07 C0 19 14 26 2B 3F 2E 3B 13 98 AB 02 00 77 71 33 20 00 00 00 00 B5 6A 5D 34 C0 55 09 15 3E 30 7D 05 00 6A 27 01 22 AA 1C 00 0C 08 14 20 FA 89 40 AA 03 00 07 C0 1B 16 29 2E 44 31 3F 13
I did it for you, made them tighter as well. A bit late... but I have a 280x with Elpida memory and found this topic&post. afaik the first 3 bytes in a row are frequency for the strap in hex . 4th byte is mem type What Eliovp posted has 4th byte changed from 01 to 00... won't this "brake" the bios?! My bios supports 3 types of memory: Hynix MFR, Elpida, Hynix AFR - in order reported by VBE7 my straps: 20 4E 00 01 33 31 33 20 00 00 00 00 61 88 11 08 D0 54 07 04 0C 07 C1 00 00 21 60 00 22 AA 1C 00 02 00 14 20 8A 88 80 A1 00 00 01 20 03 02 06 07 09 08 0D 0B 80 38 01 01 55 51 33 20 00 00 00 00 E7 A4 44 20 50 55 0B 0D 1A 97 34 03 00 26 A1 00 22 AA 1C 00 4B 06 14 20 9A 88 C0 A5 00 00 01 20 0A 08 17 19 21 18 1B 11 1C 19 02 01 55 51 33 20 00 00 00 00 AD 41 78 37 80 55 0E 10 28 21 98 05 00 4C 05 01 22 FF 1C 00 63 0D 14 20 5A 89 C0 A9 00 00 01 20 11 0E 27 2A 38 22 29 14 20 4E 00 02 99 91 33 20 00 00 00 00 60 88 11 07 C0 52 0A 06 0F 09 91 00 00 20 41 00 22 AA 1C 00 15 00 14 20 9A 88 40 A1 00 00 07 C0 03 01 05 07 08 0A 10 0C 80 38 01 02 77 71 33 20 00 00 00 00 A5 AC 35 1F 30 53 09 0C 20 98 75 02 00 44 82 00 22 AA 1C 00 44 09 14 20 2A 89 00 A5 00 00 07 C0 0C 06 14 1A 20 19 21 0F F0 49 02 02 77 71 33 20 00 00 00 00 31 5A 7B 3A 90 53 09 12 36 29 AB 04 00 68 04 01 22 AA 1C 00 74 04 14 20 CA 89 00 A9 02 00 07 C0 17 12 24 29 3B 2A 37 12 40 9C 00 03 33 31 33 20 00 00 00 00 84 94 22 10 F0 54 09 06 0F 0B A2 01 00 23 80 00 22 AA 1C 00 12 01 14 20 8A 88 00 A0 00 00 01 20 06 05 0B 0C 11 0C 10 0D 80 38 01 03 55 51 33 20 00 00 00 00 E7 AC 45 20 50 55 0B 0D 1A 97 34 03 00 27 C1 00 22 AA 1C 00 4B 06 14 20 9A 88 00 A0 00 00 01 20 0C 08 15 19 21 18 1B 11 1C 19 02 03 77 71 33 20 00 00 00 00 AD CD 79 37 80 55 0F 11 29 22 98 05 00 4D 25 01 22 EE 1C 00 6C 0D 14 20 5A 89 00 A0 00 00 01 20 14 0E 24 2A 38 23 2A 14 98 AB 02 03 77 71 33 20 00 00 00 00 31 62 9C 47 80 55 11 11 30 A7 1A 07 00 51 66 01 22 22 9D 00 6C 0F 14 20 6A 89 00 A0 00 00 01 20 19 12 2F 36 48 28 31 15
Sooo, which code 01 02 or 03 is for Elpida in my case? Thanks PS: It seems 02 is NOT Elpida, as there is no refrence to 1375 (default clock of my card) and comparing values it seems 01 stands for Elpida ... any hint if it wiull be ok to overwrite first strap of 02 memtype adding 1500Mhz strap for 01 ?

I did it for you, made them tighter as well. A bit late... but I have a 280x with Elpida memory and found this topic&post. afaik the first 3 bytes in a row are frequency for the strap in hex . 4th byte is mem type What Eliovp posted has 4th byte changed from 01 to 00... won't this "brake" the bios?! My bios supports 3 types of memory: Hynix MFR, Elpida, Hynix AFR - in order reported by VBE7 my straps: 20 4E 00 01 33 31 33 20 00 00 00 00 61 88 11 08 D0 54 07 04 0C 07 C1 00 00 21 60 00 22 AA 1C 00 02 00 14 20 8A 88 80 A1 00 00 01 20 03 02 06 07 09 08 0D 0B 80 38 01 01 55 51 33 20 00 00 00 00 E7 A4 44 20 50 55 0B 0D 1A 97 34 03 00 26 A1 00 22 AA 1C 00 4B 06 14 20 9A 88 C0 A5 00 00 01 20 0A 08 17 19 21 18 1B 11 1C 19 02 01 55 51 33 20 00 00 00 00 AD 41 78 37 80 55 0E 10 28 21 98 05 00 4C 05 01 22 FF 1C 00 63 0D 14 20 5A 89 C0 A9 00 00 01 20 11 0E 27 2A 38 22 29 14 20 4E 00 02 99 91 33 20 00 00 00 00 60 88 11 07 C0 52 0A 06 0F 09 91 00 00 20 41 00 22 AA 1C 00 15 00 14 20 9A 88 40 A1 00 00 07 C0 03 01 05 07 08 0A 10 0C 80 38 01 02 77 71 33 20 00 00 00 00 A5 AC 35 1F 30 53 09 0C 20 98 75 02 00 44 82 00 22 AA 1C 00 44 09 14 20 2A 89 00 A5 00 00 07 C0 0C 06 14 1A 20 19 21 0F F0 49 02 02 77 71 33 20 00 00 00 00 31 5A 7B 3A 90 53 09 12 36 29 AB 04 00 68 04 01 22 AA 1C 00 74 04 14 20 CA 89 00 A9 02 00 07 C0 17 12 24 29 3B 2A 37 12 40 9C 00 03 33 31 33 20 00 00 00 00 84 94 22 10 F0 54 09 06 0F 0B A2 01 00 23 80 00 22 AA 1C 00 12 01 14 20 8A 88 00 A0 00 00 01 20 06 05 0B 0C 11 0C 10 0D 80 38 01 03 55 51 33 20 00 00 00 00 E7 AC 45 20 50 55 0B 0D 1A 97 34 03 00 27 C1 00 22 AA 1C 00 4B 06 14 20 9A 88 00 A0 00 00 01 20 0C 08 15 19 21 18 1B 11 1C 19 02 03 77 71 33 20 00 00 00 00 AD CD 79 37 80 55 0F 11 29 22 98 05 00 4D 25 01 22 EE 1C 00 6C 0D 14 20 5A 89 00 A0 00 00 01 20 14 0E 24 2A 38 23 2A 14 98 AB 02 03 77 71 33 20 00 00 00 00 31 62 9C 47 80 55 11 11 30 A7 1A 07 00 51 66 01 22 22 9D 00 6C 0F 14 20 6A 89 00 A0 00 00 01 20 19 12 2F 36 48 28 31 15
Sooo, which code 01 02 or 03 is for Elpida in my case? Thanks PS: It seems 02 is NOT Elpida, as there is no refrence to 1375 (default clock of my card) and comparing values it seems 01 stands for Elpida ... any hint if it wiull be ok to overwrite first strap of 02 memtype adding 1500Mhz strap for 01 ? I just copied from the 5th group and forth and replaced with my current strap values. If yours was 02 before don't replace with 00. Use diffcompare and see which yours are closest too, Elpida and Hynix will be completely different and most values will be different.

Yes, I compared "your original values" and they are exactly same as mine for 01 mem type ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Still, naybe there is a scientific method to see which code for which memory is?

In your hex editor scroll up a few lines and you will see a few different memory types. They go chronologically, so if the first one listed is Elpida then its 01, Hynix 02, etc ,etc. If there is only 1 memory then its 00 The 280x you need to set a high core clock to get a good speed. You would need to set it at least to 1100 to get 18mh/s. These cards are getting very close to the end of their lifespan in ETH mining. Best is to also dual mine with them and you'll make 20 cents extra a day.

I used to think they were in order, then i continued on doing more mods and quite a few BIOS arent in particular order (by comparing the straps that were identical to other BIOSes) TLDR: Be careful with assumptions. Also yes dont replace the 4th Byte.

In the end I flashed one of Stilt bioses for xfx 280x, which had Elpida-only timings Results (before/after) @950/1500 ETH: 15 - 15.6 EXP: 23 - 23.8 XMR: 450 - 520 (!) Well. Result was not worth the effort and time for modding just one card, but I enjoyed the process ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

Next to it I have 2 7950's running same clocks (950/1375) @ less than 60 and 24-24.5MH/s (expanse) Just new paste, removed the stock plastic "cooler body" and fans and put 2 90mm 3000rpm 3W fans

Hello,
I installed this Mod Bios on my MSI R9 380 4GB and hashrate now is 24 MHS stable. With 980/1650. I noticed that core clock does not change anything, Even if i put 1100 or 880, no difference, only mclock change things.
Thank you Ralph!
