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.

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

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 ?

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.

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 ?

@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.

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..

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

Modding BIOS gives more spins. Don't use it to much. GPU life will be lower. At least for older 280x-290.
But 380 are much more efficient.

Not if you do it right.

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.

So no need to worry Cheesy

Thank you

Just check your heat. I'm pretty sure any one's component's lifetime is greatly affected by its own heat level. Keeping everything cool as a whole should help.

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

1650Mhz is only a 10% overclock for the memory. While many BIOSes will only clock it at 1375-1425Mhz, it's actually rated for 1500Mhz.

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.

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.

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 UEFI part of your rom ends.

Wink

You mean where the UEFI part begins, correct?

Did i say that.. Nahh! I said Legacy ;-)

Haha, no, indeed it's at the end of the legacy part, or where the uefi part starts :-)

Good, then I knew that. Tongue

Had me wondering for a second.

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...

Which version of the Hawaii Bios Reader are you using- You probably can disable it in the newest version and check the changes made and carry it over to the Tonga - Obviously it will not be exact but may help locate the area.

I have not done much bios editing lately (not with the new version of Hawaii Bios Reader) although it looks to be much better than the older version I am accustom to using.

Edited to add the following- Looking at the new Hawaii Bios Reader - you could set the Aux Voltage to Zero to disable it.
