Hello to you all,

I have purchased 3 Acer Swift3 and I am quite happy with them because they have a good performance at an affordable price. One of the 3 is a Acer Swift 314-41 with 8 GB Ram and a 512 GB M.2 Nvme disk (Western Digital WDC PC SN520 SDAPNUW-512G-1014) in original. The disk has a Sandisk controller with a maximum bandwidth PCIe 3.0 2x. I have maximized the Ram to 20 GB and also bought a traditional 2 TB 2.5-inch hdd to have more space for large files.

Now my problem: the nvme disk shows a random behaviour sometimes hooking up 1 lane (x1) and sometimes 2 lanes (x2) (see the photos). I really do not understand why. I tried to resolve the problem installing the newest AMD chipset. Also, the Bios is the newest available. The strange and annoying thing is that I have to boot up 2 times: the first time it goes with x1 speed, the second time with x2 speed!

Someone has a suggestion? Many thanks in advance.

 

Wolfgang

    Everthing ok. For the 2 acer 314-52 withe the Sabrent Rocket 512 GB i reach about 1800 Mbyte/s (because the intel architecture cuts the speed from 4x to 2x), For the 314-41 i bought a new Sabrent Rocket 1TB and now it goes up to nearly 3500 Mbyte/s which is fantastic. I am quite happy about the improvements. So have a good time!

    Hum, maybe the firmware of the ssd is bad, the only thing I can think of to exclude MB failure is to test with other ssd...

    Thanks for your quick answer. ANyway I don't think it's a problem of firmware. I made some checks. Drive seems to be ok. What about using a firmware of Dell? I think it's to risky. I don't want to brick my disk and the operating system.

    This should be dell specific so I wouldn`t use it. Well try with other drive to see if it behaves the same.

  • What you can try is to uninstall and delete the driver from the sata ahci controller, as the ssds are based on the standard driver provided by windows:
