Howzit guys,

So it seems that one of my memory slots are giving me issues. PC keeps rebooting when Channel A1 ram is plugged in. So im looking for a LGA 1150 socket ITX form factor with an m.2 slot Motherboard.

Item Wanted: LGA 1150 ITX m.2 Motherboard
Packaging Essential: Would be nice
Desired Age: Any, as long as it works
Location: JHB, Roodepoort
Willing to accept a shipped item: Yes
Ballpark/Budget Amount: R1200

Will actually pay anything at the moment. Lol

FYI, if you want full speed from a M.2 NVME drive, you'll need a PCIE adaptor. When I did this on my Z97, my M.2 (960 Evo 250GB) got ~100% speed increase.

Excuse my ignorance what do you mean? I thought it plugs straight in? I too have a z97
 
Thanks I'll have a look!
What he means is z97 boards are only pcie gen 2.0 2x capable while full speed nvme is pcie gen 3.0 4x. So if you plug an nvme drive directly into your boards m.2 you will only get like 1500 mbps out of it at most. While a pcie m.2 adapter will give you full 3500 mbps speed. But, at the same time you also loose 4 pcie lanes off you gpu. Meaning your gpu will only run at 12x pcie

That's interesting... am I missing something wont that be detrimental to the GPU?

Yes & no. Let me elaborate. AFAIR Z97 doesn't have native M.2 capabilities, so a chip is added on, to allow it to use M.2. Z97 is PCIE 3.0 natively BTW. With limited bandwidth the added M.2, has to use some SATA bandwidth (hence why when using M.2 on a z97 , SATA 5 & 6 get disabled).

The add-on card allows the M.2 SSD to run over the PCIE bus. On my setup, (Asus Z97 Hero) my GPU now runs at 8x and the M.2 adaptor at 4x. AFAIR this can only be used in multiples of 4, and are chipset (Z97 in this case) & CPU (4770k) dependent. Between the chipset and CPU, there is someway for the CPU(?) to 'add' PCIE lanes, if I recall correctly, but I think that they don't function as the full bandwidth, but I could be completely wrong. It might even be that the chipset can only "output" to the PCIE's , according to what the CPU can support, again my recollection on this is fussy.

If you look up your CPU's specs look at this - "PCI Express Configurations ‡Up to 1x16, 2x8, 1x8+2x4 "

16x or 8x on a GPU, won't make a difference, not outside of literally 1-3FPS, if that. I think there are slightly bigger differences on the 1080Ti.

My msi z97 gaming 5 has native m.2 over pcie bus aswell as SATA. Only 2x though and its pcie gen 2.0 according to msi. Anyhow i knew you loose pcie lanes on the gpu i just wasnt sure how much. My msi board even has nvme support as of latest bios update though very limited compatabillity. See link.
