Dachte tfaw lower ? besser also 16 geht auch. bringt 32 mehr stabilität im gegensatz zu performance gewinn?
Memory signal, in steps of 8 clock
Every 8th clock some access happens.
CPU, every 3-4th clock something happens.
Two MC links per dimm slot exist.
Each half of the dimm (per side) can be talked with
But only one subchannel can work at the same time (UDIMM)
Because memory works every 2nd cycle
tFAW means, target location on target iC can be activated.
ACTivated means, you open fridge and take food out.
Fridge gets warm while door is open and food gets bad if door is too long open.
You have only 2 hands (bankgroup) and 4 pockets each.
You attempt to take (read) something from fridge away.
hold it in your hands, recognize with eyes, time passes.
You put it in left pocket and close door with other hand
Happens nearly at the same time
Now if you always need delay of lets say 8 sec to take something.
Open door, find food, maybe make space, take food, check correct food, store food, close door.
Search strobe
Find collumn and row (height and left right location)
Attempt to take food (RAS starts, if you had no idea what to take before searching for food)
Move other food out of the way (RCD)
Take food (RAS still in progress)
Check food with eyes (sensing I/O check)
Check empty space (sensing I/O finish)
stove food in hands or pocket if hands are full (RAS ends)
Close door and let fridge bring back temperature to target (tRP start)
Fridge is cold and you can open door again (tRC done)
If hands are full, you put food in pocket to free hands
tRRD starts
One hand is free and opens fridge (CAS & RAS start)
And so on~
Shorting FAW just so you only can take two instead of 4 items before fridge needs to cool down
Is silly at best, and waste of time at worst
You come with big pants and big storying capacity
Sure you need longer vs with DDR4 jogging pants
But you are more efficient and running plus thinking what to take takes time too
It all adds up.
No need to try and be more inteligent than DDR5 was designed for.
You only lose access this way and at worst even stumble while moving
Because first you make a step , then you say "i walked"
EDIT:
You can take longer each RAS too
It gives you thinking time to decide what item to take and find.
Else you are like many males who open fridge, dont find anything and open fridge again to doublecheck, 30min later ~ haha
