Custom RAM Timings for GPU's with GDDR5 - DOWNLOAD LINKS - UPDATED

[niko2004x]

Is it just Polaris Bios Editor not reading the rom correctly?  Maybe I need to update...

No idea. PBE is useless for me since it is non-scriptable, windows-only gui tool.

Has anyone looked at the micron straps on the RX 570 yet?

Offsets are wrong. 204E0001 is first frequency+type.
Although it is mangled it looks like standard timings for Elpida EDW4032BABG and Hynix H5GC4H24AJR as type 1 and 2.
Nothing interesting.

Better to use hex editor. You can see that the real straps actually begin about halfway through the lines you posted and that this BIOS supports 2 different memory types.

To me it looks like Hynix H5GC4H24AJR timings (exact copy).

[bardacuda]

Wish Polaris Bios Editor supported this.

Someone will probably modify it eventually. The 5xx series just came out a few days ago so it could take time. I'm not sure if the original author still works on it...looks like the last update was v1.4 in July last year.

https://github.com/caa82437/PolarisBiosEditor

Someone made v1.4.1 and added Elpida and Micron mem support though but I dunno who did that.

Anyway you can always hex edit the BIOS and then load/save it in HawaiiBiosReader to fix the checksum.

Earlier I had tried to load up this 480 micro rom in HawaiiBiosReader and it said Unsupported Rom.

Yeah it's not for editing but just fixing the checksum after you've edited it with something else like a hex editor.

Gotcha.  I tried loading the 570 micron rom in PBE 1.4.1, and straps box is completely empty.

I assume ATOMBIOSReader will work for generating command and data table info to make hex editing easier but don't quote me on that.

You can easily fix checksum with ohgod..tool : https://mega.nz/#!zIwVXL4B!IUQOXRqWDw6L15rvN5gBgBN0hxc6ncQu5YcnG41m90g

480 are polaris cards, not hawaii

You mean PBE doesn't work?!

It does work, most 5xx bioses now contain 2 memory profiles, like elpida/micron 4xx.

[niko2004x]

Mine are correct.   From a chip-design perspective, masking off the "unused" bits would actually add complexity.  The simple, and most logical conclusion is that the fields can store larger values than are required by the specs for currently-produced GDDR5 RAM.  I also suspect if anyone took the time to look at the JEDEC GDDR5 spec, you'd at least see tRP needs to support more than 5 bits (max 31).

To be 100% certain, on my Rx470 (Samsung K4G4) I changed MC_SEQ_MISC_TIMING: 0x09D82033
TRP_WRA=51 TRP_RDA=64 TRP=32 TRFC=157 Pad0=0

With my tweaked strap using 0x09D50CB3 I was getting 29.3Mh/s, and with only the high bit of RP_RDA and RP set, hashrate dropped to 23.1.  I let it run for 15 minutes with those timings and it was stable.

I suspect for GCN1.2 devices (i.e. Tonga) that use the R9 SEQ_MISC format that RP_RDA is actually 7 bits, not 6 plus a 1-bit pad before tRP.

It is possible that we are both 'correct'.
The definition of MC_SEQ_MISC_TIMING in linux kernel is old
and corresponds to definition of MC_SEQ_MISC_TIMING in leaked(?) RAI register description file for Bonaire which is old too.
It is possible that definition of MC_SEQ_MISC_TIMING in newer architectures is different up to paddings.

it MUST work, but i don't understand why is he trying to open a 470/480/570/580 bios with hawaiibios editor ?!

stock-micron-rx570.rom @ https://ufile.io/yjdb4   (this is from MSI RX 570 4G Micron)

If you edit the bios manually and need to fix the checksum, you can load a Polaris rom in Hawaiireader (it will say unsupported rom), and then click save and it will just fix the checksum.  

I loaded the stock-micron-rx570.rom above, and just changed core and mem clocks, no strap edits, and saved in PBE.   Ubuntu kernel panics resulted.  Had to reflash to stock, and then manually edit and fix checksum.

Better to use hex editor. You can see that the real straps actually begin about halfway through the lines you posted and that this BIOS supports 2 different memory types.

The v01 straps for hynix are also in there, but the card does not use them.   Wish Polaris Bios Editor supported this.

To me it looks like Hynix H5GC4H24AJR timings (exact copy).

You're right, the Micron straps are identical

Dallase, could you upload that 570 rom please ?

Edit1:

You can easily fix checksum with ohgod..tool : https://mega.nz/#!zIwVXL4B!IUQOXRqWDw6L15rvN5gBgBN0hxc6ncQu5YcnG41m90g

Edit2:
I see now that 480 micron rom was uploaded & modified by me, but why do you want to open it in hawaiireader ?
480 are polaris cards, not hawaii

You mean PBE doesn't work?!

It does work, most 5xx bioses now contain 2 memory profiles, like elpida/micron 4xx.

There is a fork on github that already supports the 570/580 BIOS, I cannot recall which one offhand but it's one of the recently active forks...
