Samsung’s 950 and 960 Pros run at the specified speeds as long as one does not use Samsung Magic’s latest firmware update. If the latter is used two of the three M.2 SSDs changed to PCIe 1 x 4 from 3 x 4, with a two third reduction in speed.
This can be resolved with the motherboard firmware update. However, until recently an update for the X99-E WS/USB3.1 with a Haswell processor was not made available. The last approved BIOS version was 0501.
Updating to BIOS version 0602 resolved the issue and now all three M.2 SSDs run at the specified speeds.
I took a chance and upgraded the BIOS one level further, to version 2006 and everything seems to run ok.
So, here is my question:
Below is a summary screen capture of the system in question:

Sorry cannot help but a big THANKS for the heads-up! I have the early USB3.0 version of that board.

Thanks for replying Bill. Was hoping you'd already done this ...
Will try to do a further upgrade of the Bios in a week or so (working on a project right now) and will let you know.

For those of you interested in the aftermath of updating all of the BIOS' I can safely say it works without issues -
This update consisted of seven BIOS' including the last release.
Since the CPU is not being changed and after downloading all them onto my system, I used the "ASUS EZ Flash Utility" instead of the recommended "USB BIOS Flashback" to install them from my computer. Although, I was ready to do it according to the recommended procedure with a USB 2.0 memory stick should something have gone wrong.
It'll take a little over one hour to complete the process and as of writing this the system has remained stable.
For some of the upgrades there will be up to half a dozen motherboard reboots, which can raise ones heart rate
Cheers
