Speed issue with Raid 0

ragepaw
Level 7
My system has the following specs

Zenith Extreme with 1950x Threadripper
128Gb Ram
8 x Samsung Evo 960 nvme drives in Raid 0
2 Asus Hyper 16x Cards

Currently I have the 2 Hyper cards full up with all 8 drives, but I have tried various combinations of drives on the board and DIMM card, but it's not much faster than a single drive. It works, it boots, everything looks normal, it's just not as fast as it should be. It's averaging around 4500-4800 MB/Sec.

I have what looks like the same config as the der8auer video, but I'm just not getting anywhere near the speed.

I'm running out of things to try and I could use some ideas.

Which version of the AMD NVME RAID drivers are you using? I don't think ASUS has packaged up an update in a while of the RAID or chipset drivers, but both are available directly from AMD:

https://support.amd.com/en-us/download/chipset?os=Windows%2010%20-%2064

I am running the most current builds from AMD with no compatibility issues and the expected speed.

I have the current version 9.2.0.23

Asus support sent me an older version, going to try those this weekend.

How many nvme and what speeds are you getting?

So in the bios under raid config / controller information I see UEFI for all 4 drives listed as 9.1.0-00014, in the latest AMD release the release notes says it covers the UEFI, why is the bios reporting this older rev?

Hello

these are my results with 2x Hyper M.2 x16 (PCIe Slot 3 - 4/4/4/4 / "RAID" and PCIe Slot 4 - 4/4 / "RAID") and 6x EVO 960 250 GB.

Driver 9.2.0.23 - Strip Size 128K - Bios 0902

The second image are the results configured as Stripeset in Windows 10 Pro (1709) with the Samsung NVME Driver (v 2.3)

can you check you bios, advanced/raid config / controller information and tell me what the UEFi driver version listed there is? Many thanks!

I will do so when I'm at home.

Controller Information - it is "9.1.0-00014" as well...

...and my results with 4x Samsung Evo 960 250 GB in one Hyper Card (Slot 3) and 256KB strip size

Thanks a ton for doing that! Really appreciate it!

The HHWInfo64 says that all of my NVMe drives have 4x and actually lists the 9.2.023 driver ... Whiskey Tango Foxtrot?

Now under drives HWInfo show a 9.0 driver for the configuration, windows device manager under system devices shows the AMD RAID config device as the current 9.2.023 ... I'm stumped

Under Device manager / Disk Drives is there a different driver than the MS one? Window 10 64-bit current on all updates

@Gen_Mayhem702

a few questions:

- Did you install the ASUS AI Suite? This might have enabled HPET and this might slow down the system significantly?

To disable it you can run "bcdedit /deletevalue useplatformclock" on the command prompt as admin.

- Which Stripsize are you using? I noticed that 128k seems better than 64k or 256K?

- Did you do a secure erase with the Samsung Tool (You have to create a bootable USB - Stick with the tool on it in Samsung Magician)?


I have the same settings shown in HWINFO64 and it is the same Microsoft Driver from 2006 under the "Disk drives" tab in my "Device Manager"

I have to say that I also expected a little bit more from my setup but in the end I am satisfied. From what I read, Ryzen / Threadripper generally seems to have lower 4K values.
