PC Processors

[PManaus]

Good Morning!...
Is it valid to change the values of L2 and L3 in the windows registry to the values defined for our processor, and thus obtain better performance? Example: my processor has the following values:
L2=8x512=4086kb
L3=16Mb
Would changing these registers to such values have a performance gain?

According to a video I watched on youtube, we can follow the procedure below and change the registry values to the specified values of L2 and L3 and in this way obtain an improvement in performance.
1. Open the windows registry REGEDIT
2. Followed the following path
The. HKEY_LOCAL_MACHINE
B. SYSTEN
ç. CurrentControlSet
d. Session Manager
e. Memory Management

3. Click on the SecondLevelDataCache file and change its value to the value of L2.

4. Create a DWORD32 file (by clicking on an empty area) and rename this file to ThridLevelDataCache and change the value to the value of L3

I have read a couple of threads concerning your Registry entry.

Seems like leaving it at "0" is best and from what I read it doesn't really do anything as far as performance goes: https://www.overclock.net/threads/official-amd-ryzen-ddr4-24-7-memory-stability-thread.1628751/page-...
