EDIT: This is indeed a problem and Asus has been able to replicate it. Read the following thread out to the reply on another forum from today (27July) https://forums.overclockers.co.uk/threads/samsung-960-pro-running-slow-on-x299.18787451/ This looks to affect more than just the 960 Evo
I'll drop a general question here.
Asus X299 Prime Deluxe, 7820x at 4.7 , 32gigs of DDR4-3200 stock speeds, single 1080 ti FE, 960 Evo nvme, 1tb Intel SSD on Sata 6_1.
Clean Win10 install w/ only Nvidia and Realtek drivers update, rest what Win10 picked up its self.
My problem is a perceived low read/write speed on the 960 Evo. No matter how I overclock, stock clock, voltage check, whatever CrystalMark always shows around the following whether doing the test to C: or the D: partition. I've seen other postings from other people reporting the same problem in the X299 boards but its sporadic.
I have ran stock Windows or Samsung Nvme driver, checked for newest Nvme firmware, checked with Samsung Magician and per it the stick is running at Gen3 4.0x.
I can understand new platform, immature drivers, not a 7700k ipc but this makes no sense. Has anyone run into this discrepancy?
