I put my PCIe SSD (in X4 adapter card) in slot 1 and its PCIe 2.0 now.
Which SSD are you using? Do you see a performance boost?
I put my PCIe SSD (in X4 adapter card) in slot 1 and its PCIe 2.0 now.
im happy to report that with testing by @Gamer9430
the new BootROM enables PCIe 2.0 for his stock GTX 1070 in windows (BIOS install IIRC)
ill let him post the pictures
Since High Sierra betas, seems a driver problem, people reported it here on MacRumors from time to time.
[doublepost=1534337729][/doublepost]When eventually happens, it's something like this (I've made that on my rMBP, just to illustrate)

Running 10.13.6 with EFI firmware 0138 also allows the RX480 to run at 5.0 GT/s and the hdmi audio patch to work.

We have two confirmed mid-2012, but still booting. For 2009 models, we have at least five reports of totally bricked, one confirmed with a fully corrupted hardware dump from the SPI-flash.I running pretty good on 10.13.6 with the new firmware. I’m seeing less boot-delay on all drives since Alex untangled my BootRom.
It’s beginning to look like the 2012 models were hit particularly hard with the bad 0087 BootRom flash. It may be a bit early to know definitively, but its going in that direction so far.
Three yes.Could I confirm a few things from this thread and ask a few questions?
To confirm:
- Firmware flashes no longer require an EFI-enabled video card (at least with this latest beta release)
- The new firmware is back-compatible with High Sierra
- The new firmware enables ATI cards to use the HDMIaudio kext again
You don't need to install Mojave, just open the 18A365a installer and it will ask for the firmware upgrade. When the the Mojave installer reopens after the flash, you can quit it.Questions:
[*]Since it's currently tied to the Mojave beta, can I use startosinstall to bypass the video card check and install the firmware? (aka can I do this with just a Geforce pascal card installed)
Yes, but that can be subtle.[*]Does a bad flash always result in obvious symptoms - e.g. bricking or weird boot behavior?
Yes, one mid-2012 and one 4,1>5,1 that I personally confirmed. But I can say that the 2009 was modded and both had trouble with MP51.0087.B00.[*]Has anyone reported a bad flash without having modded their firmware to add e.g. NVMe?
That I can't answer for sure, I don't have any of those GPUs.[*]With this firmware, is every RX 480/580 and Vega 56/64 card capable of DP/HDMI audio in High Sierra/Mojave (when loading HDMIaudio.kext), or is it still a "search the forums to confirm" situation?
Hmm, I'll have to flash my 5,1 to see if it lets the flashed R9 280X run at 5.0 GT/sec.. as long as I can inject the DXE driver.
I get the feeling, though, that Apple is going to at least go through a few more revisions so that when Mojave GM gets pushed out the door it'll wind up flashing MPs to 138.1.17.0 or something.
Maybe before flashing it you could binwalk your ROM dump and check for the most obvious signal of a corrupted BootROM.Hmm, I'll have to flash my 5,1 to see if it lets the flashed R9 280X run at 5.0 GT/sec.. as long as I can inject the DXE driver.

Do I need these web drivers for flashed GTX680s, too? Or can I simply plug them in and be happy?
Sorry for the n00b question, but I'm new to the MacPro "quest" and just started with an old 4,1. I flashed it to 5,1 and added a x5690... Now I'd like to add a new graphics card. I started with a Sapphire AMD Radeon RX 560 Pulse OC, which worked quite well on Mojave DP6, but had some glitches on playing GoPro SloMo Videos (200fps) in Fotos.app (these run perfect on my MBP2016). I then tried a Gigabyte R9 280x which simply did not work (fans twitched but nothing more happened).
Right now my focus is on a GTX680. I found some flashed cards for <200€ on ebay which promise "boot screen support". My question is: Do I need these web drivers for flashed GTX680s, too? Or can I simply plug them in and be happy?
Thanks!

I've always wanted to have a real eVGA GTX 680 Mac Edition but the eVGA GeForce GTX 680 FTW+ 4GB w/Backplate is better made, no doubt. Don't know if the 4GB made real diff for me, but it's nice to have.@tsialex Thanks for the answer. I found very few GTX680 on ebay (Germany). The price difference is around 20€. But most of the "flashed" ones include the power cables... Would you prefer the 4GB model?
can I flash the mojave firmware directly after doing the 4,1->5,1 flash, or should something be flashed in between? thanks
I’m not sure. Apple documentation requests that you install 10.13.6 first, MP51.0089.B00.
Pre-High Sierra BootROMs, like MP51.007F.03B used on 4,1 to 5,1 conversion, don’t even understand APFS containers.
No, that's not the problem.Would booting El Cap from 138 be a valid test, or could there be a change in the flash tool along the way also...
