Intel 12900K L1 cache speed

[dvoretsa]

Hello, 

I have disappointed results in AIDA cache & memory benchmark - L1 cache speed is lower than L2-L3 cache speed. I don't undestand is it a real problem with my hardware or some sort of AIDA bug? My config is:

Core i9 12900K

Asus ProArt Z690 Creator WiFi

G.Skill DDR5 6000 36-36-36-76

Screenshorts taked with 0702 BIOS (from the box) and with 1003 (latest available). Results with 1003 is closer to what we can expect but not exactly. What's the problem may be?

Using the latest BIOS version and the latest AIDA64 beta build, please right-click on the bottom status bar of AIDA64 main window --> CPU Debug --> CPUID & MSR Dump. Copy-paste the full results into this topic, or attach the results as a TXT file to your post. You may need to enable status bar in AIDA64 / main menu / View first.

Thanks,

Thank you!  A virtualization or sandboxing environment is affecting benchmark results on your system.  Please disable Hyper-V and Memory Integrity as well, and check the benchmark scores again.

Thank you!

The problem is solved. Screenshort attached. It seems that memory latency and L1-L3 latency is a little higher than normal for 6000MHz RAM with optimized timings. But maybe due to motherboard specifics.

I'm having the same problem but Memory Integrity is not enabled nor is virtualization. This is a new build. I haven't touched anything in the BIOS yet.

I have the same phenomenon, but turning off hyper-v is normal. I think most likely you have the same problem.

 

Before turning off hyper-v

 

After turning off hyper-v. Clear the [Hyper-V Hypervisor] or  [Hyper-V] checkbox
