    Slow NVMe performance on DIMM2 slot. Slower than laptop.

    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?

    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-...ested_188027/5

    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.

    System: 1950x with Corsiar Vengance 3444 Mhz ram running at stock 2133Mhz. (everything running at stock, but CPU easily overclocks to 4 Ghz and RAM can go to 3000Mhz.)

    Yes they are different model drives but both samsung 1TB nvme dirves, the laptop was just for reference. Just to show that it's IOPS are much higher than the 1TB Samsung 960 Pro, M.2 PCIe NVMe which is currently in the X399 system. Laptop drive is slower by specs, but benchmark shows it's nearly 5 times faster for random read and writes.

    ASUS AI software uses lots of CPU don't know why. Otherwise it's a fresh system install.

    I did install Magician afterwards to update the firmware of the Samsung drive. But results are basically the same.

    "Yes they are different model drives". Answers your question right there. You'd get essentially identical benchmarks - though reversed - if you swapped the NVMe drives between your machines.

    Just because they're both made by Samsung and both 1TB capacity and even both NVMe-capable doesn't mean they're the same machine. Samsung makes lots of different (and always changing, always improving) 1TB SSDs.

    A Ford Mustang and a Ford Escort are different machines with different performances. Even though both are made by Ford and both made to be driven on the same roads with the same speed limits.

    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.

    The lower spec drive should not out perform the high spec drive by 5 to 1. It's just for comparison to show there is a performance problem.

    In the same way if that if a Ford Escort is faster than a million dollar Bugatti there clearly is a problem with the Bugatti. I don't think it's that hard to understand.

    Forget about the laptop. The drive in the system is rated at 300k IOPS and it's only getting 24k

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