MP 1,1-5,1 testing TB3 AIC with MP 5,1

[joevt]

Is that because the display (the 27MD5KL-B version) only looks for DisplayPort Alternate mode if Thunderbolt mode is not available?

Would using a USB-C cable (compatible for video) instead of the Thunderbolt cable force Alt mode? I'm just thinking of ways to make OpenCore visible on a cold boot (especially for FileVault)—the bootscreen is apparently available on a warm boot in Thunderbolt mode (although I'd really like further confirmation of this).

Yes, I think so. I think that there is no way for a Titan Ridge device (which supports both Thunderbolt and non-Thunderbolt connection) can connect to a Thunderbolt host using non-Thunderbolt USB-C DisplayPort alt mode. There would need to be a hub or dock or Wacom Link Plus or VR2 cable or a bidirectional DisplayPort to USB-C cable in-between the host and the Titan Ridge device to eliminate the Thunderbolt connection possibility. For example, the HP Thunderbolt Dock G2 has a USB-C port with DisplayPort alt mode that is separate from Thunderbolt.

On the other hand, even in Alt mode there is no guarantee. On my 4K display (LG 27UD88-W), I can get a bootscreen when connected to my MacBook (via USB-C), yet on my Mac Pro (via USB-C with the CG-TITAN RIDGE), the display turns on (when the boot picker should appear), but the screen stays black and then goes back to sleep. An image only appears once the display drivers load. Is this because of the CG-TITAN RIDGE (or maybe its firmware as @eksu has alluded to)? Perhaps someone could confirm that OpenCore is visible with the CG-TITAN RIDGE connected to the LG UltraFine 4K.

Do you have USB 2.0 connected to the GC-TITAN RIDGE? There could be a problem in the GC-TITAN RIDGE firmware or the firmware of the computer which doesn't know how to startup the GC-TITAN RIDGE. One could make an EFI driver that Open Core loads to setup the GC-TITAN RIDGE properly.

In the case of OpenCore, the resolution as well as all available modes should be listed in the debug log. For example, this is what I get on my 4K display:

06:893 00:011 OCC: Mode 0 - 3840x2160:1
06:905 00:011 OCC: Mode 1 - 640x480:1
06:916 00:011 OCC: Mode 2 - 800x600:1
06:928 00:011 OCC: Mode 3 - 1024x768:1
06:939 00:011 OCC: Mode 4 - 1280x1024:1
06:951 00:011 OCC: Mode 5 - 1400x1050:1
06:962 00:011 OCC: Mode 6 - 1600x1200:1
06:974 00:011 OCC: Mode 7 - 1280x960:1
06:985 00:011 OCC: Setting mode 0 with 3840x2160 resolution

I think that's more modes than I'm used to seeing. My thought here is that there's no reason you should not be able to use any arbitrary timing. There should be a way to insert an arbitrary timing in EFI (EFI EDID override protocol?) like how SwitchResX does in macOS or CRU in Windows. In your case, you seem to have all the modes you could want (from 640x480 all the way up to 3840x2160), except you are missing 2560x1440 and only 3840x2160 has the correct 16:9 aspect ratio.

So for a Ultrafine 5K, one could start it up plugged into the VR2 cable on cold boot then switch to it plugged in through titan ridge.

Good thing Radeon VII’s have 3 Display Port connections, are there any good Thunderbolt / USBC KVM’s or would just unplugging and switching cables work best?

There are Thunderbolt 2 KVMs and USB/DisplayPort KVMs. But neither will be able to switch 5K.

Do you have USB 2.0 connected to the GC-TITAN RIDGE?

Yes, the USB header of the GC-TITAN RIDGE is connected. Does this play a role?

I think that's more modes than I'm used to seeing.

Definitely no lack of modes, and these modes are also found when the display is connected via USB-C, although the display remains black. When the display is connected directly via DisplayPort, the bootscreen is displayed perfectly.

For now, I'll be sticking with my 4K display. While the LG UltraFine 5K provides a stunning image, the device is still quirky when paired with the cMP: in addition to the difficulty with bootscreen functionality, there also remains an issue with sleep. It'll be interesting to see if @DSM2.Hackintosh's new modified cards can give us a perfect solution.

I have issue with my flashed GC-TITAN RIDGE Rev1.0 which conflict with my Hightpoint ssd7101a1-1. If I remove ssd7101a1. Then TB3 works on Mojave and Catalina with 40G x1. Otherwise, Thunderbolt will 'No drivers loaded'
I'm use MacPro4.1 > 5.1. Anyone can help

TB3 --> Slot4
Highpoint --> Slot3 (only 1 ssd installed - Samsung evo 970 plus)

I compared boot log

 

[KevinClark]

I use a Titan ridge flashed with DSM 23 firmware in slot 4 under Mojave in slot 1 RX 580 Flashed Mac in slot 2 Highpoint 7101 A1 with 2 SSD NVME samsung and in slot 3 USB 3 Inateck card

No Open core in a real 5.1 12 cores 3,46 ghz

I can run my 2 thunderbolt 2 devices UAD satellite quad thunderbolt 2 and Apollo silver duo thunderbolt 2 on each port I have 2 boot to get connected but only see 10 GB/s

 

[seanshou]

@KevinC I'm using OpenCore0.5.9 and titan ridge flashed with DSM 23 firmware in slot 4, RX5700 xt in slot1. B
ut it's too big. So I can't put my Highpoint 7101 to slot2. I heard about the slot3/slot4 share lane. Does it the cause the issue?

 

[KevinClark]

the 7101 A1 works in full lane in slot 1 or 2 which device do you use connected to the titan ?

 

[seanshou]

@KevinC OWC thunderbolt3 dock

did you try without opêncore

Did you have to use the card in the 4th slot? I was concerned about the video card fans.

I was wanting to connect a Thunderbolt 3 hard drive enclosure...I was wondering if OpenCore was needed in 10.14 when not concerned about it being hot-swappable.

 

[seanshou]

I tried Mojave without opencore. It's same.

 

[KevinClark]

I tried several OpenCore version for titan that's seem to be in conflict with highpoint

 

[tommy chen]

it works when the titan is in slot 4 and the 7101 in slot 2

slot 3 and slot 4 shares over the PCIe switch

and yes, i have no problems with the 7101 at any OC versions

@IndioX Thanks a lot. Now I know why. But it's hopeless for my Sapphire rx 5700 xt. It's too big. I should buy below style one.

 

[seanshou]

@IndioX Do you know the size of Sapphire Radeon VII16G. I mean whether macpro5.1 has enough space to install 7101 in slot 2 and Sapphire Radeon VII16G HBM2 in slot1

All Radeon VII are reference cards, and all of them won't block slot 2.

no problems use radeonVII in slot1 and the 7101 in slot2

Hey guys!
I didn't want to cross post (https://forums.macrumors.com/threads/tb-3-cmp-egpu.2248869/) but I think I'll get the precise answer I want in this one.

I bought a Gigabyte GC Titan Ridge Card that was flashed to work (plug and play) in the cMP, mine is a mid-2010 5.1

The card is plugged in the slot 4 which was recommended in the instruction. I tested the card with a TB3 external drive plugged and I get a low Data Rate Transfer, 360MB/s read & write.

Is this due to the limitation of the PCI-e 2.0 slot of the cMP? Is my card deffective and I should expect/get higherData Rate Transfer?

The external TB3 HD is not a beast, it is a 28TB G Raid mounted in Raid 0.


Thank you guys for the help.

 

[h9826790]

The external TB3 HD is not a beast, it is a 28TB G Raid mounted in Raid 0.

If I understand correctly. That's a 2 bay enclosure.

360MB/s sounds like a very reasonable speed for 2x HDD RAID 0.

 

[Noobraino]

@h9826790
Yes 2 HDD in an enclosure mounted in Raid 0.

But let’s say i mount a 2 x HDD Raid 0 directly from the cMP drive bay, what kind of speed should i expect?

Will it be greater then 360MB/s?

What i want to know and mostly understand is: Is this card simply a TB3 connectivity ebabling card? Because if i can’t get greater speed with it then a normal SATA external enclosure or an internal RAID 0 then it is kind of useless.

IMO, the reason why your G Raid has TB3 has nothing about its RAID speed (just 2x HDD in RAID 0 can't even saturate a USB 3 connection. Not point to use the expensive TB3 connect), but it also serve as a TB hub.

In your case, the RAID array speed is limited by the HDD performance. Upgrade the connection won't provide any improvement.

In fact, if you pull out the HDD, and install them into the cMP's SATA ports, then RAID them together. You should also get ~360MB/s.

Interestingly, this G Raid rated up to 500MB/s. And 2x SATA II in RAID 0 is exactly rated up to 500MB/s. So, no matter which drives you use, you should always get the same performance regardless you use the G Raid, or install them into the cMP internally.
