Z390 Auros Ultra - M.2 Question

Recommended Posts

Posted · Original PosterOP

Hi, this is my first post here... I've been googleing around for some time now and I dont seem to find an answer to my question...

I'm just building a computer, but I've never installed a M.2 drive before. I've purchased the Z390 Auros Ultra and a Samsung 970 EVO 1TB  NVMe M.2 SSD, which I want to use as System Drive. It is obviously a PCIe drive, not a SATA drive. However, the motherboard has a M2M slot, M2A slot, and M2P slot, which are illustrated on page 20-21 of the manual:

It's not clear to me which of the three slots I should install the Samsung drive in. Considering that I maybe want to install a 3rd graphics card (2 running in SLI already) to serve the 2nd monitor and to take some load of the SLI to have more power for the main gaming monitor I guess I dont want to go for the M2P slot?

Are the M2M and M2A slots slower than the M2P slot? And what kinda confuses me is that, assuming Im reading the table correctly, the use of the M2A slot has absolut no effect on the SATA3 ports nor the PCIEX4 lane... which is kinda odd.

Can somebody out there tell me if I'm going the right way installing it on the M2A slot? Thanks :)

Install in any of the slots, although if you can I would choose one that isn't under a graphics card. All of them will be the same speed except for in the case of slot M2P while you also have something installed in the PCIe 4x slot, which you wouldn't install a graphics card in.

 

Just as an aside, installing a 3rd graphics card isn't going to give you any performance benefit. A monitor without any 3D acceleration going on makes literally no difference to performance.


¯\_(ツ)_/¯

Don't use M2M, that cuts two SATA ports of the back which you could have avoided.

 

M2A doesnt have connection sacrifices, but I'm not sure about the cooling situation.

 

M2P only has a tiny connection sacrifice (display adapters dont care if there;s PCIe x16 or PCIe x1, rendering your desktop is hardly any work) so that's a good spot if M2A is filled or cooling there sucks.

3rd GPU wont help reduce load for the gaming cards at all, rendering your desktop is just too light of a task. It only makes sense when you have so many monitors that you need more ports.

Nope, everything connected to the M.2 slots, SATA ports, ethernet, the small PCIe slots, bottom PCIe slot, USB ports etc are all connected to the chipset. The chipset then has to squeeze all that through a PCIe 3.0 x4 pipeline to the CPU. As long as all M.2 slots support up to PCIe 3.0 x4 speeds, then they are effectively the same (Aside from stuff that gets disabled).

This is pretty common for high end stuff. Only the cheap stuff make you lose ports and slots whenever you add something.


Studying abroad, ditched the crappy laptop for a do-all laptop double. Dried factory CPU paste, long memory timings, cooler cools the inductors but not the mosfets and an inch of unused internal space on both left and right

Model: HP Omen 17 17-an110ca CPU: i7-8750H (0.125V core & cache, 50mV system agent undervolt) GPU: GTX 1060 6GB Mobile (1696MHz 0.812V ~ 1860MHz 0.95V) RAM: 12GB DDR4-2666 19-19-19-43 2T Storage: 128GB Toshiba NVMe SSD (KBG30ZMV128G) + 1TB Seagate 7200RPM 2.5" HDD (ST1000LM049-2GH172) Monitor: 1080p 120Hz IPS G-sync

 

The best thing to do is reading the clock speed that doesnt end in a pair of zeros. Software voltage readings are wrong if your motherboard's not a high end model

Thanks for the replies :)

 

 

all of the slots have a cooling bracket on top so cooling shouldn't be an issue. I'll go for the M2A slot then
