Title: B350 Tomahawk m.2 Problems
Post by: Ruyazanin on 24-March-17, 16:32:41
Hi all!
I just finished my first build with m.2 SSD (Intel SSDPEKKW128G7X1) and maybe i did something wrong:
1. First of all, i make mistake in instalation. I just screw SSD using "main m.2 thumbscrew" instead of smaller screw on top (SSD was angled like this, slot on bottom, screw on top: /|). After this i booted in bios one or two times before i noticed this. I remember, i check SSD in boot panel but in hardware monitor slot was empty.
2. After i install sdd in right way i still cant spot SSD in BIOS hardware monitor, but SSD is visible in boot panel. Also i cant spot any mechanical damage, and slot system itself is quite flexible.
3. In windows it works well, but write speed is lower than i expected and i noticed huge drops when i extract archives (it takes really longer time) or doing something like this.

So, questions:
1. I broke my new PC/SSD/Ryzen?
2. Why i can spot m.2 SSD in BIOS hardware monitor?
3. This is normal or related to Ryzen freshness?
4. There is no m.2 settings for b350?
5. Maybe this is related to PCI-E lanes bandwith?

Specs:
R7 1700@3Ghz, B350 Tomahawk, 2X8Gb 2133, dual GTX670, W10

Thank you!

What is 'write speed lower than expected'? Was it 400 MB/s? 200 MB/s? Instead of being vague, be very specific. Post a benchmark. Post a screenshot. Something that actually gives us an idea of what 'lower than expected' means. 
Because right now, we don't know. And we can't really help until we know that.

Most likely the drive and board are OK.....

Extracting archives requires the CPU to decompress so SSD throughput will suffer when the CPU is bottlenecking.

Extracting archives on a Ryzen 1700 shouldn't bottle neck all the much, given how new the processor and architecture is.
I mean there will always be some overhead and the size of archives will make differences, along with the compression type, but still.  I can extract large 7z archives on my 1700 setup with ease on a non m2 based windows 10 install.

Are you using bitlocker or any other kind of encryption software at all?

Thanks for all replies!
After testing and little bit of research, testing, checking... i found SSD and mobo is OK. 
So, no problem here.
