Slow NVMe performance on DIMM2 slot. Slower than laptop.

Crystal Bench with 601 BIOS



Crystal Bench from my Laptop with NVMe drive



I have reset the bios and cleared all overclock settings.

This is causing the system to run slower than my laptop. Loading up photoshop feels like I have a sata platter drive.

Random 4k Q32T1 benchmark is the problem.
IOPS are showing about 24k to 30k should be benching 200k iops minimum.

I can't use the main DIMM slot on the motherboard to test it right now because I have hardtubing for watercooling and can't remove my graphics card without draining the whole system and undoing the fittings which would take a while.

Can anybody confirm if they are getting better results with crystal mark?

Maybe relevat to mention the NVMe model and it's firmware version.

If it is a samsung drive, are you using samsung's driver or microsoft's?

Right now using Samsung latest driver. But tired with both. There was little difference between them.
Using 1TB Samsung 960 Pro, M.2 PCIe NVMe.

Actually looks like not just two different SSD drives, but two entirely different SSD models, based off those numbers.

Which TR4 proc and how much RAM on that X399?
Which laptop model (which chipset, CPU, RAM)?
What other hardware (and other drives) plugged into those systems?
What other software is running (why is desktop consuming 19% resources vs laptop consuming 7% resources)?
Are you running any drive-specific firmware or software like RAM Cache, RAM Disk, RAPID/Magician?

I wonder if (Windows) chipset drivers can produce such significant differences. People say the AMD drivers are still imperfect but those numbers (if on the same SSD hardware) just seem too divergent to blame entirely on drivers.

Ran it on my 1950X+64GB RAM+Zenith, here's what I got

I have two NVMe drives in my system, installed in the DIMM slot. Here is the 950 pro:



960 EVO:



Running bios 0503. It seems the results of the 960 evo should be higher going by this review, hmm... http://www.legitreviews.com/samsung-ssd-960-evo-review-250gb-and-1tb-nvme-m-2-drives-tested_188027/5

Your EVO seems to be the boot/OS drive (C:\) Then it would be normal for it not to achieve it's maximum performance since it it serving as the OS drive and will never achieve its peak performance because of it.

Anyone wanting the nvme max performance must use it as a standalone drive unrelated to OS and make sure it is cooled appropriately in order to avoid thermal throttling.

We have the same boot drives and yours is showing 3 times the performance.

Making progress.

Disabled High Precision Event Timer (HPET) in windows 10. Ryzen Master needs this. So if you disable it you will have to do all you're overclocking from the BIOS.

You need to run command window as administrator.

To disable HPET in Windows run the command... bcdedit /deletevalue useplatformclock
To enable HPET as the only timer run the command... bcdedit /set useplatformclock true

It's still more than half the performance of what it should be, but at least my system doesn't feel like it's running on platter drives anymore.

Same problem here. I have a Samsung 960 EVO 500GB installed under the chipset cooler. So I'm NOT using the Dimm.2 expansion card.

What the performance SHOULD BE:


What my performance currently is (and what you are experiencing as well):


As you can see, the 4K scores are significantly lower than they should be.

My suggestion: should we install the Samsung NVM Express Driver 2.2? Windows already says that the best drivers are installed though.

CPU: 1950X
Mobo: This one of course
RAM: 2x G.Skill Trident Z RGB F4-3200C16Q-32GTZR @ 2800Mhz

Let's fix this! Thanks

Again, different hardware provides different results. That benchmark was run on a 1TB Samsung 960 NVMe and an ASRock Z270 Extreme4 motherboard. Not an ASUS X399 Zenith Extreme motherboard. Different chipset, different architecture, different design, different implementation, different priorities, different performances, different tradeoffs, different bottlenecks.

Also remember that CrystalDiskMark is a synthetic measure. It's not profoundly meaningful (accurate) in itself, it's only meaningful as a reference comparable to other measures.
