    Thanks for all the information and helpful tips you've given me, mate ;)
    Yeah, the ticket got along smoothly and quickly :)

    I have opened a new thread on TPU forums to ask how to proceed in order to share the vBIOS :)

    It's my absolute pleasure. Glad to see some of you can make good use of this :)

    Cheers!

    Ahh I see.

    Work around must have been:-

    i) flash 121kb file and then dump via GPU-Z and edit > fix checksum > flash

    ii) add FF from 1e400 to 1ffff and edit > fix checksum > flash

    I think Stilt's "gaming" version (a tweaked Hawaii BIOS, originally for mining only but also for gaming now) is better regardless of base version numbers and build dates. I use the 1000/1375@+0mV version myself and I tune it further to 1150/1375@+63mV with AB. The main differences for me between stock and Stilt are 1: I can keep PowerPlay enabled with the 1150/1375 OC (I have to force constant clocks with the stock BIOS for this much OC) and 2: the clock-to-clock difference at 1150/1375 is 63 vs 66 fps in the FireStriker 1 test (custom 3DMark mode with default settings), even 1150/1500 won't beat this with a stock 290X or stock 390X BIOS, the lower latency seems to matter when the raw bandwidth is already high enough.

    Not meaning to take this thread off topic.

    I just flashed The Stilt 0PM bios on a Vapor-X 290X and it was comparable in 3dmark Firestrike to the Sapphire Vapor-X bios.

    The Stilt 0PM set to 1100MHz / 1500MHz in AB = 10594
    Vapor-X STD or OC bios set to 1100MHz / 1500MHz in AB = 106xx

    Both tests with 50% PL & CCC 15.7.

    I guess some will find it better, others may not and by writing this I do still appreciate the time and effort he has put into making those custom roms.

    Could you share the link to Stilt's bios?

    They work on reference 290/X cards, Sapphire's Tri-X being one of them. Reduced power consumption and VRM temperatures on my R9 290 Tri-X nicely.

    Still, appreciate the updated BIOSes OP, thanks for posting. Could come in handy if I want to return to Sapphire's BIOS at some point and want a newer version than what came with my card.

    you guys do know that you can add UEFI compatibility to any bios out there right ?
    you just need to find a identical reference bios that has UEFI in it and transfer it from one to another thats based on reference.... using the patch tool then fix it with CRC then reflash and your done ;)

    So, you intentionally tuned you RAM to a clock range where Stilt's memory tweaks don't apply at all and you ended up with a conclusion that non-existing tweaks don't yield any performance benefits. :3eyes: Congrats! :infinity:

    There is but one rule to Stilt BIOS users: you should remain in the clock range of the memory strap Stilt altered. So, pick a ROM with 1250MHz default RAM clock to use RAM clocks between 1126-1250 MHz or pick one with 1375MHz default for the 1251-1375 MHz range and don't leave these ranges (except temporarily for validation/benchmark purposes).

    According to my benchmarks, 1375 MHz + Stilt tweaks yield slightly but distinctively better 3D performance than any clocks between 1375-1625 MHz with factory tuned straps (the 390X BIOS allowed me to go as high as 1625 but simply there is nothing to gain, unlike with latency tweaks at lower clocks).

    No not intentionally, my mind was preoccupied with 3x bios editing threads for hawaii!

    Thanks will re do test :)
