To answer my own question, I have confirmed that removing all the drives will cause the hiren's boot cd to be booted. I had assumed that the Used Gadgets video had shown the drives being removed to minimize power usage when two cards were in use, but now I see that it was to boot the cd. I am still puzzled why he didn't just swap out the cards instead of leaving both installed since the PC ROM version should be able to display for the flashing. Odd.
Got a tip for us?

After patching CoreBrightness.framework to use Night Shift, I might actually have to support Apple's disabling this feature as more than simply planned obsolescence.
If I have it set as Sunset to Sunrise, during the "transition phase" where it is gradually becoming orange in tiny increments, I get periodic (every 10 seconds or so, lasting maybe 1-2 seconds) framerate drops in a game. This is really unacceptable for an already slow computer, so I was forced to disable this feature.
If I leave it set at Off and just check the box to turn on until tomorrow, there is no noticeable performance hit. Therefore, I conclude that the gradual transition from normal to Night Shift'ed is what causes the lag. It must be invisibly changing the color every several seconds, and I guess this uses a significant amount of processing power.
I quite thoroughly tested this and am sure it is happening. Anyone else notice this?

I'm in a similar situ with a 21.5" 2011 iMac which works superbly. But the RoI is pretty low as it's getting on in years now. The ebay prices are in the 2-400$ range so it's not worth further investment from my perspective.
This happens even in high sierra on a non-metal card such as radeon 5770. During this time, kernel_task is eating up a ton of CPU cycles. The trick here is to just toggle it off and turn it back on and it will be ok

What exactly is this GM thing (I've never been in an Apple Beta Program before)? Is it the first official release -- or, at least, the final beta with the same contents the official release will have?
The Golden Master is a tentative release which only gets minor installation tweaks if any prior to release. If you Google that issue for High Sierra, you will see...
GM build number : 17A362a
Final build number: 17A365
so upstream did three builds in between the GM and the actual final release.
I am pleased to announce that I have Metal working on a Mac Pro 3,1 2008 without any video driver hacks for the Kepler GTX GeForce Titan 6GB original. PC Card. Not flashed.
I thought it was booting to a blank screen and locking up. But it was really using my 8800GT Card to produce a phantom screen (off screen) I was able to login using safe mode (shift during boot) and could setup and login.
Later with the phantom screen, I pressed enter password enter a few times and the system gradually came up.
I disabled my 8800GT Card by unplugging the power and rebooted again, but I also turned on automatic login just in case. My phantom screen went away.
Now with the Nvidia Titan Kelper card without any video driver hacks, it will load up with Metal v1 Family v4 which is pretty good.
Had I known the system was booting to a third phantom screen, from my other video card, I would have caught this much sooner.
This same card works with Apple's drivers on High Sierra.
My install is basic and used mostly Mac Pro 4,1 patches along with 1 patch for Platform compatibility. Tried to limit what was replaced as much as possible.
Safe mode loads most of the graphics extensions and even then the opaque UI is pretty smappy without glitches on the Titan card.
With GeForce extensions loaded that come with Mojave the system is super responsive. This is on a Mac Pro 3,1.
Extensions loaded with the Kelper Titan Card 6GB.
GeForce 12.0.19
NVDAGK100Hall 12.0.19
NVDAResman 12.0.19
NVDAStartup 12.0.19
IONDRVSupport 530
IOGraphicsFamily 530.9
IOPCIFamilly 2.9
My card is unflashed. I keep the 8800GT on standby in a x4 slot and can boot it in safe mode if needed. Either card will boot into safe mode. 8800GT also has boot options. So having two cards (on Mac EFI and one PC) eliminates my need for a boot screen on the Titan.
I am very excited to find this little break through and glad this I don't have to be tied to Nvidia Web drivers, but have the choice of running Apple's or Nvidia's in the future. And glad to report that Metal runs fine on a Mac Pro 3,1. All screen savers are operational and to me the Shell screensaver is a good performance test and it runs smooth as silk.
Was able to get this card of eBay for $250 + shipping.
There may be other Kelper cards that will work but be careful with the Mac Pro 3,1. Some cards are buggy and have to run in Slot 2 instead of Slot 1. My Titan is in Slot 1 and works fine.
Time to clone with CCC and put this on my PCI OWC 1TB SSD that runs insanely fast.
Titan cards btw are well built. My original Titan also fully supports 4K with all the scaled resolutions you can through at it. As well as it runs, I would only buy this Titan or the Titan Black. Anything else is probably overkill for the 2008. I had a Maxwell 12GB Titan X and it ran good but to be honest. This card runs just as good and it does one thing better, works with Apple's Mojave drivers.

Are you sure you weren't just over drawing the power on the PCIe bus? The specs for a Kepler GTX GeForce Titan 6GB shows 250 watts and the specs for a 8800GT are 105 watts so if you had both fully powered you were drawing 355 watts on a 300 watt PCIe bus. And thats not even accounting for any additional PCIe boards you might have installed outside of the graphics cards. From the MacPro 4,1 specs...
*This model has four full-length PCI Express (PCIe) 2.0 expansion slots, two x16 slots and two x4 slots. In the default configuration, one PCIe 2.0 x16 slot is occupied by the graphics card. Apple also reports that "all slots provide mechanical support for 16-lane cards" and there is a "300W combined maximum for all PCI Express slots."
Hence my distaste for these YouTube instructions for flashing Mac ROMs on a GTX 680 while using a second card.

If you had read my earlier post that I have rerouted power from the DVD IDE to supply power the 8 pin connector on the Titan. I have reserved the two six pin connectors for the six pin connector on the 8800GT and also on the six pin connector on the Titan. I don't know exactly how much more power the 8pin connector has but I am using the power from what would be for the two DVD ATA drives to supply the 8 pin power. I don't use DVD drives anymore so those are removed.
Also the specs on the original Titan is 250W (as you stated). Each 6 pin connector has 75W. And each card I believe is given 75W. That leaves 100W which is am sure the DVD ATA power will power 100W. Also on a Mac you are usually never gonna draw the full 250W. Many people have used the two six pin connectors but that would be about 25W short.
This card is not flashed and runs fine without issues. I have disabled the power on 8800GT card as after installation its not needed in my normal operation. So there is not draw there. Both cards will run together and I have under High Sierra has there are Tesla and Kepler drivers built into High Sierra. On Mojave, I am only using the built in Kelper drivers.
I have run into Power issues with the Titan X Maxwell 12GB card which I have sold. When this happens the whole system will suddenly cutoff. The original Titan Kepler card uses less power than the Titan X btw.
I also run mostly SSDs on my system. I have two SSD RAIDs. One Micro SSD on slot #4. One SSD RAID is on Slot #2 and another SSD Raid in my SATA #1. I have just two 4TB Hard drives that are mirrored for long term storage.
So far I have had zero power issues with the original Titan card.
I know if you try using a 1080 Ti card without rigging the power you will probably have issues and those cards I believe draw more power per connector.
All the Titan cards have 1 8pin and 1 6pin connector which makes supplying the power a little easier even though it is a power hungry card. The original Titan is not hard to supply power to on the Mac Pro 3,1 2008.
I do not flash PC Cards. And frankly have no interest and I have run both flashed and unflashed cards that are similar in my system and other than a boot screen and boot options, that's all your missing really. And keeping a stock Mac card on stand by in a slot that is not used often is a great alternative.
One thing is certain, if I boot even without a monitor on the 8800GT Card without a driver, it will load a phantom screen on it at 800x600. Removing it's power resolves this issue. I could remove the card completely, but it's a pain. I have done countless hours of testing and am very pleased with the original Titan card. Never thought I would have Metal working before the GM. I also do not have the patched Tesla drivers installed on the 3,1 as when doing so disables Apple's Kepler drivers that come with Mojave.

I sort of just lucked out it seems.
Some time ago I picked up this little GT 640 from ebay for less then $100, at the time I was running El Capitan.
It has served me well from El-Cap to Sierra to HighSierra and now to Mojave betas.
I like the fact that it's Metal capable plus I have a boot screen and no extra power cable required.

This is as close as getting a solid finder sidebar as I can get
Yes, that happens also on Metal GPUs when the main window is not overlaid, I have "fixed" this editing appearance, but the annoying issue is the finder top menubar, that is managed by the HIToolbox.framework, we need to wait for @pkouame 's "hybrid light mode" until the GM.

@Larsvonhier I think you have to use the same kexts for your GTX650 to enable full acceleration on Metal GPUFamily1_v4 in your Mojave beta with eGPU :
GeForce.kext
GeForceAIRPlugin.bundle
GeForceGLDriver.bundle
GeForceMTLDriver.bundle
GeForceVADriver.bundle
NVDAGK100Hal.kext
NVDAResman.kext
NVDAStartup.kext
IONDRVSupport.kext
IOGraphicsFamily.kext
Or replacing all from High Sierra 10.13.6 except don't touch this one in Mojave: IOPCIFamilly.kext

Hi, I created two volumes on my SSD on mid 2011 21,5 iMac and installed on one Mojave B10 and on other volume runs HS, both with exactly same files but of course different MACOS. If I compare the two, HS runs much faster and smoother than Mojave, I guess that's because of the missing accelaration. Hopefully this can be solved, otherwise I guess HS is the limit for this iMac...
I'm a "low profile" GPUs supporter too, best possible performance for lower power consumption.
Still a bit confused as why you would want to keep the 8800GT Card installed since a Titan can drive three displays comfortably.
I tried the HS ones and could not get it load the GeForce kexts and bundles. I did get metal and acceleration to work just by using mojave’s.
You can boot into safe mode by holding down the shift key, which does not load the GeForce kext’s, but lets you do some setup. This is also handy when installing other kexts or when NVIDiA drivers are released, you should be able to insall them without swapping inflashee cards.
Lucky me, using the above ones from Mojave (latest beta).
[doublepost=1536667477][/doublepost]
For whenever I need a boot screen, verbose boot or switch OS' at startup. It is on stand by and is not plugged in with power when I am using the Titan and have it working 100%. You don't know how many times I have swapped video cards out and keeping the 8800GT as a warm spare is better than installing and uninstalling the card in my opinion (and vice versa for the Titan).
My Titan is not flashed. I may remove the 8800GT later entirely but it's not costing me anything to keep it on a x4 slot without power attached to it when it is not in use for a boot. I really don't need it, except for troubleshooting (whenever that is needed).
After getting metal to work and knowing what's going on with Mojave now, it is not gonna get much usage. And I am really happy not having to flash a card for Mojave.
Also with safe boot, may not need it except for installing the OS.

Unless you are using Windows under Bootcamp much in which case the unflashed Titan is probably running at PCIe 1.0 instead of 2.0.
When are the graphics anomalies fixed? That's the only thing that prevents me from updating
I read this is no longer the case with cards that have drivers working 100%. I can't find the article at this moment but as soon as Apple started allowing PC Cards to be used in Mac OS Mtn Lion and later, that once the drivers load, it will run PCIe 2.0.
BTW, there is the post on PCI 1.0 and 2.0 with PC Cards. See #17. It doesn't mention the 3,1 only 4,1 and 5,1. So possibly it is running at 1.0 on my system, but I honestly can't tell the difference if there is. I may one day put this to a test and get another card and have it flashed, but that's gonna be long time. I would really like to know if there is a difference.
https://forums.macrumors.com/thread...out-nvidia-pc-non-efi-graphics-cards.1440150/
I also read somewhere that cards will drop up and down in speed pending how much that card is being taxed. And in many real world scenarios the difference in 1.0 vs 2.0 is minimal.
Regardless, I am super happy with the result and will be selling out my 2012 Mac mini and its Thunderbolt Display.
MacVidCards btw with the Titan X will only show 2.5GT/s even on a flashed card. He has some other way of proving it is running 2.0 speed on his site. The cost to for him to flash a Titan, Black, or X is $160.00.
There is also the bottleneck of what a 2008 can really handle. Honestly with my Titan X Maxwell (flashed) and Titan Kelper (unfleshed) there wasn't any noticeable speed difference in High Sierra. I can't say the same for Mojave because the Maxwell needs Web drivers.

That might be interesting:
In Yosemite / El Capitan there was a command you made to keep the menu bar in light mode or dark mode and the dock and other things in the dark or light mode, according to your preference, I do not remember the command, but it was via Terminal, would that work on Mojave as well? It would be one of the options.

sudo defaults write /System/Library/LaunchDaemons/com.apple.WindowServer 'EnvironmentVariables' -dict 'CI_NO_BACKGROUND_IMAGE' 1 I think that was the command by terminal it would turn your menubar white
