Hmm.. thanks for the link (and I am impressed with your contribution to this subject!), but I still don't understand the difference.
Both seem to be BootROM, both are the newest one for the Mac Pro 5.1...?
Got a tip for us?

MP51.0089.B00 is the last one for High Sierra, 138.0.0.0.0 is the improved firmware released with Mojave DP7/PB6.
When Apple released MP51.0089.B00, the microcodes were updated by Intel - Apple released a firmware with outdated microcodes from the start - but better outdated than without microcodes, like MP51.0087.B00.
138.0.0.0.0 brings 5GT/s support for all PCIe cards, even with Windows, plus other things like the current Intel Xeon microcodes and the capability of flashing the firmware without EFI GPUs.

5GT/s it's a hardware configuration, once the firmware sets it, macOS uses the setting from there. I tested with 10.13.6 but two other users tested with 10.6.8 - one reported doubling the SSD RAID throughput even with 10.6.8.
The new EFI firmware flasher works from 10.13.6 too, but some cards, RX 480 reported by two users, are not working with the new one and they had to change to EFI GPUs to flash.
Thanks for the info. If some cards (particularly NVIDIA) are having issues, I'll hold off on updating right now. Have a few too many upcoming deadlines to mess around with that risk. Just updated to MP51.0089.B00 and no issues with GTX 1080 FE, RX 580, or GTX 680 official Mac version.
i also have installed this
MP51.0089.B00
BootRom
for HighSierra,
but now my old partition with Mavericks is all the time going active - inactive on the active windows? Very annoying, hope i did not mess up my system.

I know Mojave is out already but my Mac Pro updated via small Mac Store updates to 10.13.6, but my bootrom is still MP51.0087.B00, do I have to download the full installer and run it to update the bootrom?
As for mojave I have to get one of the compatible AMD Metal capable cards first, I know there's a new bootrom now but is it possible jump from 0087 to 138.0.0.0.0 with the Mojave installer? or I have to be on 0089 first?
