Did you try the latest BIOS yet? I'm tempted to wait just a little bit.
My guess is that this is a BIOS or chipset related issue after reading the posts here.

Yes I tried the latest AGESA 1.0.0.4 update for my Aorus Elite and no improvements.

In any case, here's my MP600 for reference. I really hope Corsair figures out why this is happening to so many people.



Edit: I benched the MP600 in Atto, as user Seege suggested, and look what we have here! (Write speeds are on the LEFT mind you! Additionally, Windows task manager reports the real throughput to be about ~0.2GB/S higher than ATTO when speeds exceed 2GB/s or so.)



Looks like CrystalDiskMark doesn't play ball particularly well with our x570 boards..?
I then went back to CDM, and messed around with filesizes & passes. Turns out the results are very inconsistent in CDM. In one test, I get the advertised speeds(!)... And in the next SAME test I get 1GB write speeds.

Lads, should we check the integrity and compatibility of our benchmarking tools instead, or are these fluctuating results caused by the drive itself?

it's caused by the drive itself... try to copy/export ...etc the writting speed will be around 800MB/s so CrystalDiskMark is giving real result

I hope Corsair succeed to reproduce the failure and firmware patch coming soon.
And I hope not a defective memory control chip or memory chip causes the failure.

Thanks for checking in. I hope Corsair finds a remedy to this issue fairly soon, or customers are gonna jump ship. (get it?)

I've just opened up an RMA request in regard to this issue; my drive has been this way since I received it in August and I assumed at this point some kind of firmware update would be out to address it... but at this point I'm out of hope so an RMA is the only option.

I'm seeing consistent sustained write speeds of around 800MB/s which is pretty ridiculous considering the 2TB Intel 660p that I got for $200 performs better. I'm hopeful that the hardware swap will resolve the issue though.

Running an Asus x570-pro motherboard w/ a 3900x and the latest bios/chipset drivers available to date.

No your speed is fine, you just use different settings for you benchmark. If you compare sequential Q1T1 to Q32T1, they will be lower. Set your Queues in Crystal Disk Mark to something higher like 32 and you should have the full speed.

Curious are most people here with issues using the Asus Crosshair VIII or higher?
And people without issues on the asus rog strix x570-e gaming

Anyone with these issues on asus rog strix x570-e gaming

Hi everyone, I'm still here. I've just been trying to balance everything out. I have received two more FA RMA units and will test accordingly once some other tests are completed. Should have some comments tomorrow.

As of right now, I'm not really sure what's going on. On my testbench (ASRock X570 Taichi), as I've stated, the one RMA'd unit I've personally tested achieved speeds that were on par with the advertised speeds. Again, I'll test the two other units, hopefully tomorrow, and I'll share any findings (i.e. if the results align with what's shown here or if they're proper speeds).

If you have submitted an FA RMA on an MP600, can you DM me your name, so I can discuss my findings in more detail with you? Thanks!
