It's not hard, but congrats on handing it to idiots.

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.

When did he ever try and sell them? He's been giving them away for ages.

What a fuck you are, a new guy shares his work and you shit on it.  Your ROM's are shit Eliovp and you try and sell them.  There are plenty of people that make ROM's and I am one of them and I have yet to see anything spectacular in any of yours.

Here he is selling them- I do believe he is aka Heliox

Plus. I know a bit more than copying straps..
Ask me to add VDDC, MVDDC/VDDCI/AUX offsets and i'll do it.. not so sure if you're able to do that ;)

I make my own and use them, I certainly do not sell them for a profit.  It is obvious from his posts that he thinks he is the only one that can make ROM's and decided to crap on the new guy that was trying to be helpful.  The guy has been on this forum for 1 month and apparently pissed off a few people if you read the above posts.

It seems the guys with a bunch of posts should go around a bully other people here.  I can call Heliox's ROM's shit in rebuttal to him making the new guy look like he accomplished nothing.

Lastly, I will be more than happy to compare a ROM to his anytime.  What card would you prefer we compare?  Let's do something like a 390x - What stats do you want to compare- speed? 

You know what, i changed my first post.

Because honestly, you're right  ;)

eliovp, so what did you do to have ~37Mh, bios change or just clocks?

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 :)


Ps. Read this

And read the replies as well!

Look at his post, people come on here and get crapped on for trying to help out.  Instead of offering the guy constructive criticism.

Very nice ROM, I have a few similar ROMS and gave yours a try and like it a lot.  I used it on some Powercolor 380's and they run stock at 980/1450 and I set them to 925/1650 and get a stable 23.8-24.1 mining Eth only with claymore's.

I have a couple that will run at 950/1675 and hit 24.5 but only about 50% have been stable

Props for a nice ROM

Edit2: @nerdralph: Here's a hint to make it even more faster. If you remove the last straps (anything about 1500) in other words end the table with 1500Mh, you'll get even faster hash ;)

If you're claiming to change MVDDC through the BIOS on R9 380 cards, I'm calling bullshit on that.  While there might be MVDDC offsets in some Tonga BIOSes, it's no good to you when the memory voltage is not programmable.  I've physically checked (with a multimeter) the voltage on a few 380 cards, and the memory voltage is fixed at around 1.55V.

As for ending the table with the 1500 strap instead of 1750, I don't think that should make a difference, but I'll try it anyway.

@Eliovp  If you think it's exactly the same as one you shared, I'm guessing you didn't have your coffee yet when you looked at my ROM.  Or maybe, je bent raar.  Here's the 1750Mhz/Elpida timing from the 380nitro ROM you posted:
And here's mine:

Guess which one is faster? :-)

Yeah i'm claiming that :) Check my post i said MVDDC/VDDCI <-- that means, MVDDC or VDDCI :).

The elpida part :)

That timing isn't faster on mine though..
But it's nice that you put them together, if you look closely you can see the difference and "why" it's faster ;)

Greetings!

En nee, ik had mijn koffie nog niet!

Excuses voor de directe reactie, maar lees mijn bericht maar eens op dat ander forum dat ik hier gepost heb..
Je helpt niet hoor.. je maakt het slechter ;)

Groeten!

OK, VDDCI (memory controller voltage) is something I'd like to control.  Every 380 BIOS I've checked varies it along with the core voltage according to the dpm state rather than according to the memory speed.  So VDDCI ends up higher at 980/1475 than at 900/1650... which just seems stupid.

Just to be clear, are you saying the Elpida 1750Mhz strap in your 380nitro BIOS is actually faster than mine for mining eth?
I get 24.0Mh at 900/1650 using Claymore.  Even though I use Genoil's (my fork actually) for my rigs, I use Claymore's for testing since it reports more stable hashrates, saving me the trouble of averaging Genoil's numbers.

As for your last comment, I had to resort google translate.  I'm fluent in English & French, but for most other languages I'm limited to hello/goodbye, a couple insults and a few swear words...

p.s.  It does appear you've deleted the part of your post claiming mine is exactly the same as the one you shared...

So how do you figure out exactly whether 01 is Hynix/Elpida or 02 is Hynix/Elpida ?

I always assumed 01 was Hynix

EDIT: Btw, 02 isn't always Hynix.

Exactly, adding that offset will not only make your cards consume less, it'll make them more stable/faster.

That strap makes no difference for me as my 380 doesn't clock higher than 1625, anything over that will give incorrect results and instability. (mainly because on the one i'm using here the highest strap is 1500 ;))

I've deleted that hours ago, even before you started replying ;)
.

Ah, bon, mais Francais est aussi possible :)

Le choix est vôtre  ;)

So how do you figure out exactly whether 01 is Hynix/Elpida or 02 is Hynix/Elpida ?

I always assumed 01 was Hynix

So it's just an offset to VDDC?  I'd like to keep VDDCI fixed, while still having VDDC change according to the dpm state.

So at 1625, are you getting much more than 23.6Mh?

Français aussi?  Tabarnak!  Combien de langues est ce que tu parles?

The numbers are arbitrary.  It's by the timings you can tell which is which.  Look at the BIOS for a card that only supports Elpida to find the standard Elpida timings.  Compare that to the timings in your BIOS, and if one of the type 01 timings matches, then you know it is Elpida.  Same thing for Hynix.

Although I haven't tried it yet, I suspect the two (Elpida/Hynix straps) are interchangeable.  I have tried changing a few of the individual timing entries with the goal of making fully custom straps, but it's too much work for too little benefit to try to figure out all the timing values.  GDDR5 doesn't just have RAS/CAS timings, it has things like the four activate window (tFAW), 32 activate window, and more.
If I could get my hands on an AMD BIOS developer's guide, it would be much easier...

Hello,

can you explain difference between 380NR and 380NR1150 and 380NR1100?

Thanks

cReepas

This is what you want  ;)

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

No it's an offset to VDDCI/AUX, they both have seperate offsets in the rom. In 90% of the cases you won't find VDDCI offset, so you can add it :)

8D = VDDC , 8E = VDDCI/AUX or MVDDC

Agreed.  I've seen another ROM that had just a single set of straps and used type 00 for Hynix.  I imagine it is just an enum in the BIOS code.
The way I figured out that it is Hynix for the Club3D BIOS I modded was by comparing the actual timing values to another BIOS that only supported Hynix.

You're starting to surprise me..

I think i missjudged you..   ;)

That's what i've been doing, but there has to be sure fire way to look it up the reference somewhere in the BIOS. The order at which for example Hynix/EPI/Sam are referenced in one of my vBIOS arent in the order their straps appear either. I was told to check in the vram info table but atoms bios reader doesnt seem to have a clue.

Maybe there's a more complete tool out there? (I think i heard there was)

I don't have anything better than atom bios reader.  If it helps, the JDEC mrf ID for Hynix is 0xAD80.

You add it in VoltageObjectInfo. Note this changes the length - this means go back and fix ALL the offsets in the main table lists, and check your padding at the end to keep the size right.

You mean where the UEFI part begins, correct?

Not only those things. Also need to change the starting pointer which states how long the table is.
+ you will need to make sure the rom has the exact same size as it has before.
This doesn't mean, scroll way down and remove some FF's. No, you'll need to remove these where the Legacy part of your rom ends.

;)

Sorry to interrupt you guys, but can i have a noobish question ?
If i copy the timing nerdralph gave from a 380 nitro ( 77 71 33 20 00 00 00 00 EF 51 6A 37 90 55 0F 12 32 17 9A 05 00 6A E4 00 22 AA 1C 08 74 02 14 20 CA 89 C0 A8 02 00 00 C0 15 10 23 28 59 28 33 15 ) to my Asus Strix 380 4GB 1750mhz strap, will it be better than copying my own timing from 1425mhz ?

Ugh.  Now I really miss Hawaii with it's really simple VDDCI table.  :-(
If there's an easy way to completely disable VDDCI control, I might try that, and just control the NCP81022 through i2c.  If I can figure out how to read the memory errors from the HWinfo source, then I could could write a small program that cranks up VDDCI until the memory errors drop below a minimal threshold...

Just a quick question : does this huge memory overclock affect my cards life drastically ?

So no need to worry  :D
Thank you

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?

Edit: Forgot to mention, currently working on shedding rops, will "hopefully" have a working result by the end of this week :)

how about to mod bios so 280x can give at least 20MH?

@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.

how about to mod bios so 280x can give at least 20MH?

Replace them :)


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:

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 ?

Yes, I compared "your original values" and they are exactly same as mine for 01 mem type :)
Still, naybe there is a scientific method to see which code for chich 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.

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 ;)

The card already is hitting 70deg on open rig...
Perhaps after I find time to change the paste...

i started TongaBiosReader  but i don't see where are the memory timings i can change?

i notice i have all 380's with samsung memory

when i use msi afterburner
asus default is 1375 max stable 1385
xfx is 1400  max stable 1470
sapphire 1400 max stable 1470

i uploaded my default bios here (i write 4G but s its all 2 G)

https://drive.google.com/drive/folders/0B_VgPvwZ9TTcZ0RCSTRmSjdkb0U

if someone could put the right timings

thanks

You cant change mem timing with tongabiosreader, you must do it in hex editor, just google it.

I have one of those - it SUCKS. Somehow, even with *custom* timings, not a copied strap, it STILL sucks ass.

You do have a history of letting your ego cloud your judgment.  :-)
Remember the bitcanuck R9 380 thread in the ethereum forums?  You were convinced that reducing the core clock would reduce eth hashrates, but you were wrong.
I can't find the thread any more, as I think one of the mods deleted it.  I could probably find it with the wayback machine if you've "forgotten" it. :-)
Come to think of it, you're a mod on the ethereum forums, aren't you...

ıf u use dualmıner try -dcri 9 -cclock 885  -mclock 1625

i get 24 mh/s with 380 strix so no, it doesn't sucks so bad.

just modified it myself with a hex editor, copied straps.
r9 380 2gb strix can go even higher than 24 mh/s

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!

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.

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.

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.

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 :P

https://s23.postimg.org/b8if5ys2f/Screenshot_15.png (https://postimg.org/image/b8if5ys2f/)

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.

Hi Im new to modding, once Ive bricked my card,
But I could recover with the backup vbios Ive created!

I have an MSI R9 380 4Gb Gaming with Hynix memory!
I have stock 19mhs with blockchain driver.
I could max OC it by 1100coreclock, 1500memclock stable at afterburner doing 21-21'5mhs.
Could someone drop to me a good vbios for my card?!
My Original vbios (https://anorak.tech/uploads/default/original/2X/1/147b79d833efb063aafe75544484fc763ee5fd72.rar)

which version of amd drivers are best in your opinion for modded r9 380 (msi hynix mem)?
i've tried many... new ones and olders and it seems 16.9.2 gives fastest hashrate....

hello. I am a newbie with mining. I have three R9 380x 4Gb (1 Gigabyte, 1 Powercolor PCS+, and 1 MSI) but only got 17.3 MH/s for each card using stock setting.

My first question: which driver version should I use to get 20+ mh/s? I am using Windows 10 Pro.

I still have 78 x R9 380's along with the rest of my other cards (old and new).  You should be getting 20 MH/s each card STOCK.

You need to use a DDU to UNINSTALL your current DISPLAY DRIVER (DDU) in your 380's.  Then install the Blockchain Driver.

Hi dmwardjr,

I am now working on flashing. I wonder what settings I should use for the following cards for lowest power consumption. At stock setting, they are using 190-200W each. It's pretty high for me. I'm ok with 20.5Mh using stock setting but wanted lower power consumption.

Gigabyte 4Gb _ Hynix
Powercolor 4Gb_Elpida
XFX 4Gb_Elpida

I also could not find a modded Bios for my Gigabyte card on Anorak. If you have, please share.

Thanks.
