Custom R9 380 BIOS for 23-24Mh/s

[Eliovp]

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

...

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.

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


Yup try ending it with 1500, or 1625 if it can't handle it

I already shared something like this a while ago.. So no, you didn't do anything special..


Ps. Read this

And read the replies as well!



Edit: i opened up the rom and i laughed.. It's basically exactly the same as the one i shared 

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.

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

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

@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:

Code:

77 71 33 20 00 00 00 00 B5 6A 7D 46 C0 55 10 15 3E 1D 1D 07 00 6C 07 01 22 AA 1C 08 0C 08 14 20 FA 89 00 AB 03 00 00 C0 1B 16 2C 31 71 31 3F 17

And here's mine:

Code:

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

Guess which one is faster? :-)

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!

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

...

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.

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

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.

I already shared something like this a while ago.. So no, you didn't do anything special..


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

And read the replies as well!



Edit: i opened up the rom and i laughed.. It's basically exactly the same as the one i shared 

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.

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

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

@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:

Code:

77 71 33 20 00 00 00 00 B5 6A 7D 46 C0 55 10 15 3E 1D 1D 07 00 6C 07 01 22 AA 1C 08 0C 08 14 20 FA 89 00 AB 03 00 00 C0 1B 16 2C 31 71 31 3F 17

And here's mine:

Code:

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

Guess which one is faster? :-)

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!

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...

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

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

I always assumed 01 was Hynix

In most cases it is.
But as mentioned before, not always.

This is mainly so when there are multiple tables. i.e for both Hynix and Elpida

EDIT: Btw, 02 isn't always Hynix.

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.

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

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?

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

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...

[Eliovp]

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

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

Not more but the same

Hello,

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

Thanks

cReepas

380NR leaves the voltages dynamic (which is based on the chip leakage ID).  380NR1150 and 380NR1100 modify the last 3 DPM states in Voltage Table2:
380NR1100: 975, 1050, & 1100mV
380NR1100: 1025, 1100, & 1150mV

380NR1100 will use the least amount of power, but needs a GPU that can handle close to 100mV under-volting.  380NR1150 uses less power than 380NR, and should be stable with most cards.

[adaseb]

The 380 Elpida timings that you posted? Any chance they would work on the 7950/7970 with Elpida memory?

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.

I did it for you, made them tighter as well.

Ok thanks. For some reason the speeds are the same as before.

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.

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

So where would you add it?  I only recently found ATOM BIOS reader, and still haven't figured out the dynamic voltage control for Tonga.
I know when Voltage Table2 in PowerPlayInfo has values that start with FF, that indicates dynamic voltage control.  Otherwise it's just the voltage in mV for that DPM state (i.e. 84 03 = 0x384 = 900mV).
For the values that start with FF (i.e. 0xFF08), I think the 08 is an index to another table that contains values for calculating the dynamic voltage.  But I haven't found where that table is in the ROM.

I copied the 1500Strap from the 380 Bios that was posted here and replaced the timings from

However speed only increased by 0.1MH/s. Maybe its because my core clock is only 950Mhz since its undervolted.
