poor performance from 980 pro

extrememachine · 20 Feb 2021 at 22:12

So installed the 980 pro on a pcie card for m.2 ssd.
I am getting much lower performance and on samsung magician it is stating "Use pcie 4.0 for optimal speed". This may sound ignorant but if i put the ssd on the actual motherboard slot will i see better performance?
I'm using an asus R6 E mobo btw.

What performance are you getting and how are you measuring it?

im using samsung magician getting 3500mb read speed

I'm guessing the drive is being limited by the fact you're on PCI-E 3.0.

So no way of getting full speed on this mobo then?

No, you are limited by the type and speed of your PCIe ports, in this case Gen3. The 980 Pro is a Gen4 NVMe drive and needs a Gen4 M.2 slot to run at full speed, so unless you replace the motherboard and CPU the drive is running as fast as it can.

Are there any 2066 SKT mobos with gen 4 slots?

Unfortunately no, Intel don't currently have any PCIe 4.0 support until they release Rocket Lake and even then you you are looking at a new motherboard. Otherwise you are looking at AMD and again a new CPU/motherboard.

Probably not "poor peformance" by many a measure, just less than is possible. I wouldn't imagine it to be any measurable difference in your applications outside very specific use cases, i certainly wouldn't be upgrading core components for the sake of some applications reported performance scores.

+1. Unless you were planning on an upgrade, I would just use it at the current speed until a future upgrade on cpu mobo when required.
