Wanting to run an ADT-Link R43SG on my thinkPad X1 Yoga 3rd Gen, 8350u & igpu.
HKEY_LOCAL_MACHINE\SYSTEM\HardwareConfig\Current\BootDriverFlagsĪnd set it's value from 0 to 0x1c (Hexadecimal, 28 Decimal), this flags control which drivers are available at boot time, and Yes it's possible, You would need to go to regedit and edit the So the default BIOS setting on these "U" Elitebooks do not need to be tinkered with to maximize eGPU performance. Only once PCI Express power management was disabled using the HP BIOS Configuration utility, the ZBook matched the Elitebook FPS performance.
Disabling Windows PCI Express power management didn't improve the ZBook performance. With a GTX 1080 Ti M.2 eGPU, Forza 4 benchmark gets 80FPS on a i7-8850H ZBook G5 and > 100 FPS on a i5-8350U 840 G5. Given the sensitivity found with the 840 G5, would advise against the Riser White and instead stick with ADT-Link adapters with soldered cables. So it's sensitivity to adding addition edge connectors along the eGPU link might differ. Clever modularization that reduces engineering costs. The 14" 840 G5 and 15" 850 G5 use the same internal systemboard. If the above extenders work, I'll have fallbacks I actually don't mind the laptop damage much, it's the intermediate state that would be hard to debug, if the connector loses firm contact with the m.2 connector.Īnd that it took 1 Month for the R43SG to get here. I'll check the config, but isn't "PCI Express Power Management" in windows power management as well (PCI link state something.). Is there a 2X link with something like a USB cable? or some other detachable. I ordered R42SL to see if it would be easier to work with, and provides the same functionality.Īnd Riser White 008S NGFF M.2 just to try 1X link with VR. Posted by: laptop is 830 G5 but I guess it's the same as 840, just smaller. So I'll get a minimal riser (see link) so it would be less wear on the R4SG.ĭrawbacks: Remove eGPU each time (slightly less wear on PCIe connector), and need to carry the R43SG everywhere.ĭo you think something like a ADT R42 m.2 to 4x + (4x -> 4x PCI ) riser/extender work? or does the elitebook needs some delay or something the It would be like a cartridge swap, for power I can solder some quicker connectors.ĭrawbacks: Remove eGPU each time and replace it another card (wear on PCIe connector), and need to carry the R43SG everywhere.ģ) I can connect to my work network via vpn, so I might just use my second SSD externally for gaming at home and for work. If that would work (m.2 -> pci-e -> m.2). I'm even running 3.1 gen, and oculus rift S connected to the eGPU.īut I'm worried about disconnecting and reconnecting the (fragile?) m.2 connector of the R43SG.Īnd I got the shortest one for the least signal issues, but it the most stressful on the connector :/ġ) Extending the M.2 externally via R44SF extender, but I don't find many that it worked for them.ĭrawbacks: Needs to screw m.2 connector in each time, and I'm not sure how durable is the m.2 connector.Ģ) Use PCI-E to m.2 (see link)and just keep the R43SG connected somehow, and replace the external pci-e from GPU to the encrypted work M.2 SSD. I don't notice any performance difference running from usb and having a m.2 4x eGPU That will cut some into their gaming laptops (and some desktops) business, but they allowed thunderbolt. Just wire a few PCI lanes to external port what so complicated about that ? I hate that we still don't have external pci, with no uneeded (unless you want long cables support) costly interface such as thunderbolt.
I'll install windows on my other SSD (while it's internal) and test it externally to verify the procedure and update the main post.
On the plus side, the external SSD will be bigger, and I won't have to worry about isolating work stuff. Not a short break endeavour :/ Maybe end of day. Now, I'd have to shutdown, remove the internal M.2, connect eGPU instead and boot to external SSD with different OS (and games). I wanted to use the same work drive for the eGPU os, so we could do short gaming breaks (With oculus rift S VR headset) while compiling longer projects and stuff like that The preboot decryption/validation used in mcafee drive encryption 7.2 doesn't like this configuration.
Sadly IT re-encrypted the drive, and I can't test which flag worked right now (hw config one, or current config one, I'm guessing the current config one).
