@vastunghia Could you run "Memory benchmark (1 min)" on your 5D3 using 1.1.3 firmware in Play mode?

There you go:



Is this in line with your benchmarks? Could you please translate this stuff for an ignorant like me? I expected to see some result near 150 MB/s, but cannot seem to find any.

Thank you

Sergio

Ps: let me remark that I'm on build 2022Apr07, while many others seem to be using 2022May15. Could this make any difference at all?

Thanks, numbers same as my 5D3 (margin of error differences):

5-D3-Memory-Bench" border="0

I thought yours would be faster in some tests. It's always better to make sure.

No idea where ~150 MB/s limit comes from . .

P.S: also I used same build as yours.


Ah, I just got a thought . . do you know what picture quality you set from Canon menu? because it changes memory layout. It might affect write speed.
Waiting some new DIGIC 5 models . . .
