Hi guys looking to replace 4*HDD with 2 8tb NVME storage drives - my mobo - i9900k maximus code XI has 2 integral NVME slots, one of which is occupied with a system drive.

I have a spare PCI express slot (x16) and was wondering if i were to put a pice E adaptor in would this work ok with the mobo and not halve the graphics card performance or something?

If it would work ok is there any adaptor that people would recommend? i've been looking on OCUK and can't find a full pice slot one?

Cheers!!

Which ones are you looking at? Normal m.2 drives by Corsair/Sabrent?

Intel 9900K only has 16x PCI-E lanes coming from the CPU, therefore any additional lanes used are coming from the chipset, unless you turn the GPU down to 8x, and run the second slot with a PCI-E to M.2 adapter card, and ensure the slot support bifurcation or you'll only see one drive. The chipset only has a 4x link to the CPU, and that is all shared with every other device connected, and as such should be avoided for connection fast storage if you actually want to benefit from the speed, otherwise just buy some cheaper SATA SSD's.

The GPU will happily run at 8x with little to no performance loss in games, but if you are doing actual work with the GPU, then you will lose out.
 
Thanks for the response guys

If you use the 2nd gpu slot the graphicas card will run at x8 th6d bottom pcie x16 slot shares bandwidth with SATA6G_56 ports. PCIe x 16_3 slot is set at x2 mode by default.

Yeah the 3090 covers all slots bar the bottom PCI express so not getting at slot two even if I wanted.

So basically a PCI express adapter in slot 3 will run at twice the speed of a SATA drive? That seems fine for a storage drive?

I'm looking at doing a WC setup but don't want to compromise storage deleting the HDD cages

Already have a Sarbent provided by work was going to get a Corsair off OCuk - I've been trying to work out if even putting in an additional M2 drive in the motherboard second slot will impact the performance of anything (the system drive is a 980pro NVME).


I was looking to delete sata and power cabling as part of the setup (glass panels on both sides).

So in summary I hope this is right;

Sticking additional NVME drive on second mobo slotwill be fine.

Sticking single nvme drive in slot 3 via adaptor meana a X2 SATA speed drive?

Adding a second m2 will b3 fine cant see any info saying it affects gpu performance but check the motherboard manual as there mite be further info there.

Pcie x 2 slot is going to give you a speed of approximately 1500mbs not sure what size m2 your after but take a look at the adata xpg sx8200 pro

The system only has 4x PCI-E 3.0 bandwidth (via the chipset) for both of those slots, so it is shared between them, meaning if you were copying from one to the other you'd get half the speed.

The only way to resolve this is to use some of the 16x lanes reserved for the main GPU PCI-E slot, via a M.2 adapter card, the manual should in fact have this info in it as well.
 
Can recommend the Startech x8 dual m.2 PCIe express adapter.

It has a ASM2824 switch to split a x8 slot to x4x4 without the need of bifurcation support in the bios.

The attached nvme won’t be as fast as using a single dedicated riser but it gets around the bifurcation issue if your second slot doesn’t support x4x4 - no wasted lanes :)
