Can't install Windows. X99 WS Fault?

Attempt using the USB 2.0 ports at the rear I/O.

I loaded deafult UEFI settings, saved and rebooted with my 8 GB USB2 Windows 7 Pro x64 SP1 OEM installation stick attached to a rear panel USB2 port. Windows 7 was installed within a few minutes. I've yet to install all the drivers for all hardware but will do so shortly and then repeat the process across the memory slots B1, C1 and D1. The bad news is that I appear to have 2 dead memory sticks from Kingston.

Thanks for the update!

When I read your post about testing the Kingston memory, it sounded like that a problem with the Kingston memory.

BUT, since you installed Windows with only one DIMM installed, I would be concerned a little bit about the other DIMM slots. Not that bad slots are a common problem, but you never know until you try. Good luck with it!

I forgot to mention earlier, a couple good things to do when dealing with new memory:

After changing or just moving memory around, a UEFI/CMOS clear is always a good idea.

At the bottom of the DRAM Configuration screen, you should find an option called MRC Fast Boot, set to Enabled by default. Setting it to disabled will cause memory training to occur during POST. That helps with memory stability.

What do I do with the unopened 2 Kingston sticks? Do I open them, plug then in and test them? If they work great. If they don't I will have opened all 4 and have to return them to the supplier.
