Here is another look at the 860 EVO - with Rapid mode but reverted to the in box drivers - same sad result...



Gonna take a lunch break and move some components around....

Cheers

Here is one more look at the M2. This is with ALL drivers (NMVe and AHCI) set to default in box. And for good measure I reset the BIOS to optimized Defaults:



If you look at the history - this drive is simply fading away. Of the four performance runs I logged - it is getting slower and slower as I change bits here and there

Next up - going to bench it and move the M2 drive and SATA connections around.

Cheers

And what about updated bios?

And what about updated bios?


Bios has been at 2004 since before anything was installed. That was the first thing I did back on Friday.

I am wondering now if I might want to flash back to an earlier version tho.

FWIW: I benched the unit and removed all my PCI cards and reseated the M2 in it's original slot (M2_1) to no avail.

Going to move it to slot 2 now (M2_2) and see what happens there.

If that does nothing - I am going to flash back to the BIOS before 2004.

Will report back.

Sonic.

I meant my updated version on raid mode :)
If an earlier version works better,we can mod that one too

I do not use RAID and will never need to - so I am not going to mess with that right now

So...

This issue has been solved (sort of). Realized after about 2 days that I still had Driver Verifier turned on. :kookoo:

After shutting that down - I am getting psuedo normal speeds for the 970 - but the 860 is still acting strange (and slow).

Back to the drawing board.

Cheers

Just another quick follow-up - I made the decision to exchange the ProArt motherboard (for another) AND decided to try my own experiment by adding the ASUS Hyper M.2 16x PCIe card (after reading Fernando's experiments about using the PCI card for the M.2 vs using an M.2 slot on the board).

I must say - while I was a bit skeptical about adding yet another card into the system - I cannot believe how fast this same SSD is in the Hyper M.2 16x card VS using the M.2 port on this board.

As soon as I laid the OS down and started the main build - it was clear I was on a different level with this combo. The Hyper M.2 card is so fast that I never did get around to testing the actual M.2 port that I was connected to at the start of this thread. Did not even bother to remove the heatsink or anything.

Will stay the course here now - I can't imagine this drive going any faster. FWIW: Give this PCIe card a shot if you haven't yet. I am now a convert.

Cheers!

Sonic.

@SonicMojo:
Congratulation for having found the reason for the performance problem of your Samsung 970 EVO Plus (bad connection) and for being able to solve it.
As a consequence I have customized the thread title.
Enjoy your refreshed system and the performance of it!
