BCLK overclock on ADL

[bscool]

Can anything be done to get accurate results on Alderlake when OCing BCLK?

 

It give inaccurate results on both DDR4 and DDR5

 

Video showing result. Not my system. But latency is actually in the 48 to 50ns range

 

RWC are also about double what they actually are.

In the video they were using an old version of AIDA64 that didn't yet include full support for Alder Lake.  We recommend you to use the latest AIDA64 beta on Alder Lake:

Also, it's not clear whether any sandboxing was used in the video.  We recommend disabling both Hyper-V and Memory Integrity to get accurate benchmark results.

It still does the same thing with newer versions.

 

Also Hyperv and Mem integruty are disabled on my system. I can post cmo or txt file for bios if needed. Let me know what you need and Ill send what info I can.

Here is a screenshot and photoworxx is also way off with bclk oc as you can see.

 

Also included bclk@100 at 7000c32 for comparison

Adding IML Intel Memory Latency checker with same setting shows it is more accurate with bclk oc.

bclk OC still broke on 5944

 

Edit I see notes dont include ADL.

We've fixed the issue in the latest AIDA64 beta update:
