Tech Inferno Fan Posted October 5, 2016 Share Posted October 5, 2016 6th Gen i-core systems have Gen3-8Gbps Southbridge PCIe Ports Owner's of the latest 6th-gen i-core systems have seen a speed bump to Gen3 speed (8Gbps) for the Southbridge PCIe ports provided by the HM170/QM170 chipset used to host mPCIe/NGFF ports. This is highlighted in RED below. Gen3 capability is however a lockable feature. Anyone contemplating buying such a system is best advised to use hwinfo64 to peruse the link speed status of the wifi card to see if indeed it's running a Gen3 speed. Reference CUDA-Z Host-to-Device Bandwidth NGFF.M2-32Gbps (x4 3.0): 2842 MiB/s link (17" Clevo P870DM-2) TB3-32Gbps (x4 3.0): 2288 MiB/s link (17" Clevo P870DM-2) TB3-32Gbs (x4 3.0): 1500 MiB/s link (12" Asus Transformer) TB2 -16Gbps (x4 2.0): 1258 MiB/s link (2013 15" MBP) TB1-10Gbps: 781 MiB/s link (2012 MBA) TB1-8Gbps (x2 2.0): 697 MiB/s link (2012 13" MBP) EC2-4Gbps (x1 2.0): 373 MiB/s link (12" Dell E6230) Previously 2nd to 5th Gen i-core systems have Gen2 (5Gbps) Southbridge PCIe ports. 1st gen i-core or older have Gen1 (2.5Gbps) Southbridge PCIe ports Soldered cable eGPU adapters best to attempt a Gen3 link Anybody with one of these systems wanting to attempt a 8Gbps (Gen3) link is best to try using BPlus eGPU adapters with their soldered cable (PE4C V3/4 or PE4L 2.1b). EXP GDC's socketted cable often has reliability issues trying to maintain even a lower specced 5Gbps (Gen2) link. 2 Link to comment Share on other sites More sharing options...
bloodhawk Posted October 5, 2016 Share Posted October 5, 2016 I can confirm the link speeds over the M.2 ports on the Z170 chip-set. (P870DM-G) using a PE4C v4.1 . Will see if i can check thing with my friends GT72VR (or something) 1 Link to comment Share on other sites More sharing options...
