ASRock Z170 Extreme4 SLI with PCIe SSD

[Simon_Larsen]

I'm considering upgrading to a 6600k cpu with the ASRock Z170 Extreme4 motherboard. However, I'm uncertain if I'll be able to run SLI in the future if I decide to get a PCIe SSD.

The CPU has 16 lanes (2x8 for SLI), which would leave no lanes for a PCIe SSD at x4. However, I've read that the Z170 chipset might leave 4 lanes open for storage use? Would I be able to run SLI at x8 while running a PCIe SSD at x4 using the mentioned motherboard?

Thanks in advance for any feedback

According to the manual at ftp://europe.asrock.com/Manual/Z170%20Extreme4.pdf the Ultra M.2 Socket (M2_1) is shared with SATA3_0, SATA3_1. This probably indicates that the M.2 socket uses the chipset - and NOT the CPU lanes. I will assume this is correct unless someone corrects me.
