Latency mesage SOLVED !

Today's result :

That looks really good.

Some questions ?
- If I move home directory on to an other drive, will I get less latency ?
- Same question if I replace ddr 1333 ram by one that have more speed?
- is it better to have one or two ram device?

No matter what you do will help, it is as good as it gets.
Memory has little effect on latency except when a memory module or memory controller is failing, HDD/SSD have effect on latency, sometimes a lot, power saving options and the south bridge on the main board have the most effect.
It is better to have 2 DIMM memories than one as it enables the dual channel memory use.

Waiting for upgrade with 2 SO-DIMM 1866MHz 4Go Cl11 and 1other SSD 250Go.
I have fixed the latency and setup Stepconf to get 60kHz step pulse.
Now I can run LC without any latency message.
In this video ou can see It running « not in simulation »
