Hi @Molo 

How are you testing this, with AIDA bandwidth test? You might want to check background activity, as this will happen if something is putting light load on the CPU.

HI @Silent_Scone 

I test with aida32 section  cache&mermory benchmark.

Today after a shutdown . The L3 cache is restored with low ns .

Why ? The temperature is perfect below 90C cpu ,Ram memory below 50C fan for cooling ,Aio Corsair 360mm on sheet kryosheet + frame secure , VRM  below 55C with case Corsair 5000D with 10 fan (6 for the radiator )  . ALL the software is closed in the 2 test with aida32 . % use by system below 3% of memory before the test .

Overheating of the puce ?L3 collison of paquet? 

I play today on  mwiii. Because when i game after 1hr or 2hr i have extrapolation,latency warning after i test the benchmark aida32 and occt idem resultat high latency L3 .

Too i another person with a board prime z790-a+13700kf and idem problem. Lantency high in L3 cache.

thanks
