Hello 🙂

I've mounted a watercooled PC with Windows 10 64 bits with an Asus motherboard Maximus VIII Hero, on a Samsung SSD M2 950 pro (see my profile for details).

Everything works, but sometimes i have some bugs, and the performance of my SSD is very bad :

When i go to the bios (v.3504 or previous version), i see nowhere the option M.2 !

Friendly,


First off, is the drive running the latest firmware?

Also if the system is overclocked, try at defaults - including no XMP profile.

Hello,

Any other expansion cards installed?
Try using both PCIE4 and the M.2 socket.

If i understood properly, no expansion card except my sound card Creative SB X-Fi, installed on the PCIe slot N1 :

And my video card radeon R9 200 ?

Where should i try to install my SB X-Fi eslsewhere ? I've got a watercooling that makes any changes very difficult

I use the M.2 slot.

If i can't solve the issue, i will buy these kind of adapter

But it will be difficult because of my watercooling system that is taking a huge place

Is a cristal disk bench enough for you ?

Edit : BINGO !!!

I just have updated my Windows 10 with the update 1709, and now everything works perfectly !

But guess what ? My sound card Creative SB X-Fi is desactivated, i don't hear any sound from my computer.

So there is a link between my poor performance of my 950 pro and the PCIe slot used by my SB X-Fi !

Thanks for having focus my attention on additionnal cards, if everything goes well when i will turn on the sound in a way or another, i won't come back here.

Thanks again, i'm lucky because i was annoyed by this for half a year 😄

Wishing you all the best,

Depending on the slot, bandwidth is shared. This is in the manual.

Glad it helped
