Intel Technical Advisory

PCI Express 3.0 Add-in Adapter Support Issue

The BIOS option "Processor PCIe Link Speed" will not be visible if the platform employs the Intel ® Xeon ® Processor E5-26xx V1, E5-24xx V1, E5-16xx V1, or E5-46xx V1 families, and the BIOS will limit the PCIe slots speed to PCIe* 2.0 speeds unless the add-in adapters have been tested for robust operation at PCIe 3.0 speeds. Refer to the web https://www.intel.com/content/www/us/en/support/articles/000007457/server-products.html page of PCIe* Gen 3 adapter support for Intel® Server Boards S4600/S2600/S2400/S1600/S1400

Hi Vshtopor,

Thank you for sending us detailed information about the issue and the results of Intel tools. I have sent you a private message with a possible workaround.Regards,Miguel C.Intel Customer Support

Hello, Vshtopor,

The higher revision of the riser might improve or not the bandwidth performance. According to the tested SSDs with the Intel® Server Board S2600GZ, only PCIe 2.0 is supported.The Technical Advisory 1021-5 didn't provide an alternative riser to use. It provides only RAID card models.For your second question, it is not possible to install directly the SSDs to the board; this configuration will damage the drives (overheating issue).Regards,Miguel C.Intel Customer Support
