    So FP64 is 1:4 and not 1:8 or 1:2 as previously known? Reply

    Yep, looks like they changed the cap in vBIOS based on feedback.

    Which also means they could have uncapped it, but it's still cool that they did that.

    Does that mean it could be potentially unlocked by some bios mod? Reply

    I don't think it was ever reported or assumed to be 1/2 - that best possible ratio is only for the pro MI50 part. Early reports said 1/16. Reply

    For what it's worth, when we first asked AMD about it back at CES, FP64 performance wasn't among the features they were even throttling/holding back on. So for a time, 1/2 was on the table. Reply

    Asrock just posted vBios: is this with the FP 1:4 or newer?

    We're not currently aware of any Radeon VII cards shipping with anything other than 1/4 rate FP64. Reply

    So maybe it's new bios with some fixes?
    Did you tried it since all cards are the same reference design?
