NVMe M.2 SSD

[nay_nay]

Hi,

Have installed two Samsung 970 EVO Plus 1TB, Internal, M.2, (MZV7S1T0BW) Solid State Drives one in socket 1 M.2 and the other in socket 2 M.2 on a Asus rog crosshair viii hero wifi Motherboard.

Installed samsung latest drivers and when I run a speed test using various softwares it only shows speeds around 2000mb/s

What could be causing these lower speeds as 970 Evo Plus are PCie GEN 3 so would be expecting to show in 3000mb/s range?

Any feedback greatly appreciated.

Thanks

Nay

Hello, @nay_nay 

May I inquire about your current BIOS version? Do you have any relevant settings in the BIOS?
It seems that your M.2 SSD specification is PCIe 3.0.
Could you please adjust the PCIe slot to GEN3 in the BIOS setting to see if there's any improvement in the speeds?
Please provide the name of the software you used to confirm the read and write speeds, along with screenshots of the test results.
Thank you.

Hi,

Bios version 4402

Adjusted both the M.2 Slot 1 and M.2 Slot 2 to GEN3 in the Bios as those are the slots I am using for the M.2 SSD's.

Hello, @nay_nay 

May I ask if the situation you described happened after any changes were made?
For example, updating the BIOS or connecting an external device
According to the official website of the ROG Crosshair VIII Hero (WI-FI), the latest BIOS version 4501 was released on 5/23.
It is recommended that you update to the latest version first, perform a clear CMOS, and then reconfigure GNE3 in the BIOS settings to confirm the transfer speed once again. 
Please also ensure that your drivers have been updated to the latest version.
If the read/write speed issue still cannot be resolved, kindly provide the following information to assist us in attempting to replicate and confirm your issue:
- the current BIOS version and the images of the setting in BIOS, or whether it is the default
- the brand, model name, and part number of the DRAM currently installed
- the brand and model name of the CPU, GPU, SSD/HDD, and PSU currently installed
- the OS version and OS build
- contains a video that completely captures the problem's incidence and the surrounding environment

Thank you.
