A:Answer It is 16GB of DDR5, one stick. It used to be 4800 speed in October 2022, then from November to now 6000, but there is no speed guarantee as any DDR5 can be installed.
One stick is completely sufficient for daily use (web, emails, texts, and gaming). I measured data speed: one stick gives 88 gigabytes/sec; two sticks give 97 GB/s.
I also checked the effect of memory speed on performance with this PC, and see very little difference, particularly in gaming:
MT/s GB/s ns FPS
6600 104.7 61.1 167
6400 102.2 61.4 167
6200 100.9 60.8 169
6000 97.2 61.7 167
5600 91.1 64.6 164
4800 79.0 73.8 163
where:
MT/s= million transfers per second, a measure of memory speed
GB/s= data transfer gigabytes/second, useful for pro publishers rendering graphics images
ns = nanoseconds, average delay in data transmission (lower value may help videogames slightly)
FPS= frames per second, the main parameter for videogames (FPS>30 means less jittery image)
Results show 6000 is the sweet spot; this PC is well planned.
