Will I need 5930k?

[breadturbo]

I've sold my 4790k and just grabbed a 4k screen, now I am going X99.

I currently run 2x TitanX and an m.2 ssd for the OS, I wish to add a third Titan for extra fps goodness but I also want to add in one of the pcie ssd cards as a game install drive, will this overdo it for the 5820k?

I am looking at the Asus X99s board and this is straight off the OCUK description?

40-Lane CPU-
5 x PCIe 3.0/2.0 x16 (x16, x16/x16, x16/x16/x8, x8/x8/x16/x8, x8/x8/x8/x8/x8 mode) *1
1 x PCIe 2.0 x4 (max at x4 mode) *2
28-Lane CPU-
3 x PCIe 3.0/2.0 x16 (x16, x16/x8, x8/x8/x8)
2 x PCIe 2.0 x16 (x1 mode)
1 x PCIe 2.0 x4 (max at x4 mode) *2

The m.2 and card ssd's both require x4 pcie3.0 I believe(but I admit to being clueless about this 'lane' business)

heeelp!

If you use the first and 3rd PCI express x16 slot, you will not get it full 16x-16x even with a 40 lane CPU (5960x, 5830K, 1650v3, 1660v3...). It is because the 3rd pci express x16 slot only physically support x8.

as you can see, you need to use 1st and 4th slot to get the full 16x-16x. That would make the system looks a bit weird is it?

Well slot 1 would be a gpu, slot two the m.2 card (thats where asus say to stick it) slot 3 a gpu, and slot5 a gpu.

I am happy with x8,x8,x8 as single cards can't saturate x8 3.0 yet (I've read) however thats 24 lanes then add in another x4 for each of the m.2 and that's 32 lanes, I was wondering if the 28 lane of the 5820k is a set in stone limit that meant this wouldn't work?

I believe one of the items will be disabled, probably the m2 drive. I have 3 titan x and an m2 with 5930k and all is good.

3 nvidia cards leaves 4 lanes free on a 5820K, 4 AMD cards leave 0 lanes free on a 5820K.
nvidia does not allow x4 bandwidth for SLI, however AMD does.

5930K is pointless unless you want to run 4 nvidia cards, or 3 nvidia cards and lots of other lanes, AMD allows x4 so you can run a lot more lanes.

Given what you want to do, you would need the 5930K due to each drive requiring 4 lanes, with the 3 cards and the drives you are looking at 32 lanes.
Although why you want 2 m.2 SSD's I do not know

Instant loading - 3seconds from power on to desktop, and so I can sit on the wait screen while everyone else loads into world of warships

Thanks for the advice folks, I grabbed an X99-s, a 5930k, and 4x4gb of the 3ghz kingston predator (running it at 2666mhz 13,14,14,[email protected])

It's nice to have intel LAN again and none of that stupid killer gunk Gigabyte seem to be using recently
