90 hours and my memtest on 8Gb ram isn't finished yet: normal or not?

[stun]

Hi,

I'm running a memtest86 (v. 5.01) on a Lenovo X1 carbon gen3 (2015), because its (unfortunately solded) 8Gb ram seems to be defective: https://i.imgur.com/RzIlyQm.jpg

When I tried to use the multi-CPU mode, it freezed: https://i.imgur.com/n3qUqVd.jpg

So I have to run it in single CPU mode.
Almost 90 hours after for, it's still not finished:

Is it normal? If yes, Could you please tell me an estimated time for a complete pass?

Thanks in advance for your kind help

MemTest86+ is not our software. MemTest86 (without the plus) is the original RAM testing tool.

MemTest86+ we believe isn't being maintained at the moment. No one is doing customer support, nor fixing the numerous issues that have been reported, nor adding support for new hardware. We don't provide support for the + version.

If you run into issues with our MemTest86 we can take a look.
