Modded Stuff here:
470 Nitro 4GB Hynix, but it should work with other 470s 4gb as well.

I'm getting 115~ Sol for Zcash.

Running rock solid since 17 hours.

I'm using 4x this model:

the other card is an ASUS AMD Radeon R9 280X DirectCU II with Hynix Memory using adaseb settings.

Here's the Asus Rom if you want to take a look
asus.rom

Forgot to tell I'd like to know the exact model of the card and if possible a URL with a picture.
Please also reply with exact "Memory Name" taken from the ASUS MemoryInfo 1005.
Other people can get this if they have exactly identical videocard.
66 to 86 Sol/s is a very good improvement, but looks like there is also faster vBIOSes around when looking to 4th card on the picture

Here it is

Thanks

i surely will

Happy I can help, nice to see such a improvement. Before flashing it to all the rest do some long term testing and reply to this thread how it went

Working like a charm...

dev3 is the flashed card. dev4 is an ASUS with the adaseb flash.

dev0,1,2 still unflashed.

Thank you so much

Dump the original BIOS with AtiWinFlash for example, then upload it, post a download URL and let me look what I can do.

Can you please make something for R9 290 tri-x 4gb. I can't find any custom bios for this card, main point is that for mining this are good cards but they spend to much electricity.

That's what's done for the .rom, for 7xxx cards I mostly input the CRC checksum manually as hex, if not possible then by using VBE.

To fix the check sum open in VBE7 and re-save.

Don't, try this instead:

The CRC should be corrected now.

No rush.
I'll try to flash it to one card.

Nah, didnt work.


Thanks anyway. Hope you find it. 

atiflash will complain the vBIOS is not found. Let me look where is your vBIOS CRC located at so I can insert it properly. Don't expect quick answer.

VBE7.0.0.7b says "Invalid checksum"... safe to flash it with atiflash?

If you can post your BIOS in the other thread
https://bitcointalksearch.org/topic/hacked-modified-memory-strap-bios-database-for-zec-mining-1676474

To keep the threads clean, i'll update the main post with your links.

Try this and see does it tell about vBIOS not found since i cant check CRC https://drive.google.com/open?id=0B-c7FrbyofW0XzV3clp1Zi0yM0U

Here it is:

Alright I finally found a good ELPIDA timing strap. Use only 1500 Mhz. That Gigabyte 7970 finally gets 80 Sol/s using this, previously it was max 70 Sol/s

Put it inside your bios, I am too lazy to do any more Hex editing.

This has only 9 timings so make sure you include an extra dummy timing so the length of the file is the same.
