:: Kasvain's Modded vBIOSes for AMD videocards  ::

This thread is mainly for discussion about my releases. Please post your vBIOSes to some another thread if they are not left for modding
I have done so called memory strap mods for some AMD videocard vBIOSes lately just for fun. I'll keep a list of all modded vBIOSes in the first post.
The major thing in the modification in these is a faster video memory achieved by using modded memory straps and sometimes lowered voltages to achieve better effiency.
I'm using all the modded vBIOSes myself I've posted in here and will update to newer if doing changes to ones already posted.
Every vBIOS will have some information about it and what card it's made for and so on. I don't take any kind of responsibility of any damages or loss made by my modifications. Use with own risk. Always backup your original ROM first, I recommend strongly using AtiFlash or AtiWinFlash for backing up the original vBIOS and for writing the new vBIOS.

Ellesmere XT - ASUS AMD RX480 ROG STRIX OC 8GB Core / Memory both stock - vCore stock, memory straps from 1375MHz up to 2000MHz.
This is a OC model vBIOS. The OC model does have a 1330MHz core instead of 1286MHz. If you card can handle a little higher GPU clock speed, feel free to use it.

Really looking forward for this.
You need the original rom of the Club3D 280x RoyalQueen 4GB?

Post a download URL to the original vBIOS and I'll check can I modify it. If a modification can be done, I'll post a download URL to the modded one and you have to reply how it works so we can add it to the list.

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.

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

[adaseb]

If you can post your BIOS in the other thread
https://bitcointalk.org/index.php?topic=1676474.0

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

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

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.

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

Nah, didnt work.

C:\_oc\atiflash>atiflash -p 4 Club3D1250.rom
Invalid PC BIOS image

   ERROR: 0FL01

Thanks anyway. Hope you find it.

Don't, try this instead:

The CRC should be corrected now.

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

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.

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.

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

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

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

[Gaglam]

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
