Durhamranger · Mar 18, 2021

Hi All...

Can anyone shed light on as to why my optane 900p 480gb has such low Q1 scores

Drive is Operating at pcie 3.0 x4 mode....

Cheers Ranger

Are you asking why your Q1 speeds are "only" 180/170 MB/s instead of (?) or why Q1 is slower than Q32 in general?

Yeah Q1T1 Scores are low compared to other systems, although this has improved with the latest bios for my Asus Crosshair Hero VII...

OK, I also have a 900p 480G and getting your numbers (the ones with updated BIOS)
Why you think this is too slow? To what are you comparing them?

Intel systems can get over 300 Q1T1 scores depending on system, I suppose its like comparing apples to oranges ....

Looks like a bug/glitch in the southbridge.
My Optane on an X570 via the southbridge, for reference:
