Samsung 990 Pro 2 TB NVMe Low RND4K Q32T16 reads and writes on X570 e Gaming

Hello to everyone

I just Bought a Samsung 990 Pro NVMe to replace my 970 EVO. I migrated the old in to de new drive using Samsung magician and then, when testing with CrystalDiskMark, my Random numbers look way off comparing with the same test from other guys.

 

My system is:

CPURyzen 3700x

MotherboardAsus strix X570 Gaming E

RAM32 GB G.Skill 3200 (8x4)

GPUEVGA RTX 3080 Ti FTW3

PSUEVGA superNOVA 850 G2

Operating SystemWindows 10

I have the latest BIOS and just enabled DOCP and used m.2 linx gen 4 on both drives

The drive is in the first slot and I have the 970 Evo in the other that also performe badly (and always have)

I have the latest firmware installed

CPU performance hits 35 % ish when doing the test

Drives reaches 50 C so i guess thats not overheating

mine:

My BenchmarkMy Benchmark

other guys

Other People BenchmarkOther People Benchmark

I think my 4k alignment is ok in both drives:

 

970 EVO970 EVO990 PRO990 PRO

Do you know whats happening?

Thank you in advance

Hi there,

Make sure to select NVME Mode in Crystal Disk.

13900KS / 8000 CAS36 / ROG APEX Z790 / ROG TUF RTX 4090

Its selected 🙂

Could be a number of reasons. Not least of all that it’s two different versions of the software, different profile, background activity, firmware, etc.

thats not helping...

Unfortunately neither is cross referencing different versions of a benchmark, or system the drive is used in not being a consistent comparison. It’s also possible there has been a change in NAND between the comparison you’re referencing.

As above, system activity also plays a role here. You’re using the drive as an OS drive. The drive you’re using for reference is clean, and is not.

1. Test at optimised defaults (clear CMOS).

2. Check drive temperature with HWINFO.

3. Format the drive and retest (if able, make sure to back up if required).

 

 

Have you tried AS SSD benchmark? 3DMark?

Done and still same results.

 

I also did a 1 thread ressult and apparently I get even better result than with 16...
