Stress test for L3 Cache (L3 only) would be nice.

[Droiyan7]

Ryzen infinity fabric for ZEN and ZEN+ (Ryzen 1X00 series and 2X00 series) make memory overclock more useful but complicated.

Sometimes, overclock fails even if both memory modules and memory controller works well but infinity fabric fails.

 

There are claims that AIDA64 Cache & Memory Benchmark is useful to see if that happens.

If L3 performance significantly lower before overclock, it is fail even if every other test(Testmem5, HCI Memtest, Linpack, etc...) succeed. Because Ryzen (exclude APU) 1X00 and 2X00 series have distributed L3 cache across 2 CCX which connected by infinity fabric, infinity fabric fails affect L3 cache performance.

So......how about allow us repeat L3 bench only (N times or time basic) ?

 

 

Or, maybe adding options to see L3 performance results in already exist cache stress test ?

The Cache subtest of the AIDA64 System Stability Test stresses all cache levels.
