Hey guys!
I am wondering if anyone knows if this baby ( https://support.hp.com/gb-en/document/c05903000 ) can be used with a Razer Core X Chroma (I think it has TB3). On that link it says it has a TB port, but that is all I know...
Thank you!
@mehenn It has a Thunderbolt 3 port but only 2 PCIe lanes. The good news is you may use the NVMe M.2 slot inside for better eGPU performance. @Nando4 has built one and it posted impressive numbers. If you prefer Thunderbolt 3 connection for convenience and power delivery, I’d recommend going with the HP EliteBook 840 G6.
Thank you! How portable will be with the M2 connector? Won't that be sticking out of the bottom of the case prone to tearing up?
@mehenn , Elitebook 840 G5/G6 are very nice laptops. If getting the FHD non-touch version, look for the automatic light sensor (ALS). System equipped with the ALS come with the 400nit LCD, rather than the non-ALS 220nit LCDs.
For eGPU use, my 840 G5 with a M.2 egpu was very fast, eg:

Problem there is the system only has one M.2 slot. Theoretically, the SSD could be swapped in/out but given the value of data, it’s hardly practical. The better solution is to use the WWAN slot to host a x1 2242 SSD as discussed, liberating the x4 3.0 M.2 slot for eGPU use. Or use a TB3 eGPU.
Some other pointers:
– HP’s recent BIOS disables undervolting You’ll want to rollback to an older BIOS if wish to unlock undervolting and increase TDP.
– the dGPU model has a beefier heatsink, useful if undervolting/TDP unlocking and wanting to turbo the the highest multiplier without temp throttling
– 840 G5 has a 2-lane TB3 port due to the Kaby Lake CPUs having only a total of 12-PCIe lanes.
– 840 G6’s Wiskey Lake CPUs have 16-PCIe lanes. HP could now have a 4-lane TB3 port but couldn’t find verification of it anywhere.
