Asus Rampage V Edition 10 issues with 960 Pro

[Paludis]

I'm having issues with my motherboard or 960 Pro. The Samsung 960 Pro (1TB) only runs at a read and write speed of around 100Mbps, the system lags and the usage is always around a hundred percent. I ask myself if the 960 gets insufficient lanes or something. I've got two 1080s of which both get assigned 16 lanes, so there should be 8 lanes left with a 40 lanes CPU, right? I contacted Asus by phone and email with no success so far. Other posts on the internet didn't help either.

*System:

*Asus Rampage V Edition 10
*Intel Core i7-6850k

*Windows says the 960 works fine but it just doesn’t.

Hey Paludis...

Where is the 960pro? in the NVME slot or in a PCIe lane on a card?

If it's in the NVME slot on the chipset it should be running independent of PCIe lanes and slots on the left...

Did you do a clean, UEFI install with no other drives connected?

[Paludis]

Yes, I installed it in the m.2 slot not via pcie. And did a clean Install with no other drives connected. I also changed drivers to the standard nvm express ones from microsoft

Where are you measuring read/write speed? What is telling you the 100 Mbps?

My system is similar to yours, and I have a few additional bells and whistles. Mine works fine so far as I can tell. I use Samsung drivers from what I remember when installing.

[Paludis]

I measured both with Samsung magician software and crystal disk mark

[davemon50]

You might try uninstalling and reinstalling drivers. Frankly I would suggest using the Samsung driver.

[Paludis]

I did already reinstall the driver. And I‘m also using the samsung driver at the moment

[davemon50]

Your second post says the opposite? That's the way it reads to me anyway.

[Paludis]

Let me clarify: I changed the drivers to the standard one from microsoft. That disnt work so I did a cöean reinstall of the samsung driver which I had on my pc from the start. I simpöy tested with the microsoft driver

Can you go into your BIOS and check the following settings:

• BIOS > Advanced > PCH Configuration > PCI Express Configuration > AUTO
  
  
  
• BIOS > Advanced > System Agent Configuration > NB PCI-E Configuration > AUTO (for all of the slots)
  
  
  
• BIOS > Advanced > Onboard Devices Configuration > PCIEX4_1 and Front USB3_34 / back...... configuration > AUTO
  
  
  
• BIOS > Advanced > Onboard Devices Configuration > 4-Way Configuration > AUTO
  

....or the highest generation/speed available. I use AUTO for all.

These are how I have mine set. Sometimes it seems the speeds (GEN#) get screwed up, and this may affect your M.2, because it shares resources, at least with one of them.
