Skylake With Crossfire/SLI + M.2 SSD

[SpencerUk]

Hey chaps,

Needing to sanity check something inside my head here.

If you got a Skylake chip (6700k) and got 2 GPU's and got a M.2 PCiE SSD how would the lane allocation look. From my reading it's got 20 Lanes so would it be 8X 8X 2X?..Would that have a knock on effect to performance speeds of the M.2 and GPU's?

Spotted a 6700K at £275 and I'm awfully tempted...Saying that, I've also spotted a 5930K at £370 and a 5820K at £300..

CPU has 16

Chipset has 20 (the SSD's will be on this)

Ok so how would the config work exactly? Little confused here.

Your GPUs would both be running at x8 each, using the 16 lanes on the CPU, and your M.2 would get x4.

As far as performance of your GPUs would be affected, there is less than 1% difference running PCIE 3.0 16x vs 8x.

The 5930K has 40 PCIE lanes in total (all on the CPU) so both GPUs would get x16 and the SSD would get x4. The 5820K only has 20 lanes in total so you'd be getting x8 for the GPUs and x4 for the SSD.

So all in all, there's really no difference and nothing is gonna get strangled out per say. Pointless then really to get a 5930K if there's barely any difference and because I've dithered on the deal its gone.

So boils down to a 5820K or a 6700K again...For the sake of £60 difference may as well go for the former but the latter can potentially reach 5ghz (silicon lottery permitting)

Remind me to buy you a point if you're ever at Sheffield Tap

the short answer is yes, you can even raid M.2 SSD's with skylake.

But not for OS

But not for OS

i thought it was as the raid is done on the mobo, i'm going to look into it.
