AIDA64 Bullshittery

[.Apex.]

Need help to confirm memory degradation on Coffee Lake CPU's specifically 8th Gen but 9th Gen is welcome as well, It happens only in Windows (even after multiple clean Installs over time) but in Linux it's performing and scaling exactly as expected and the same results that I used to see 1.5 years ago before all of the mitigations and BIOS updates, memory overclocking became mind-numbingly boring and frustrating because no matter how much I tighten the timings I get the same results.

 

As an example on 3000mhz CL15

Windows:

Read: 38GB/s

Latency: 50-54ns

 

Linux:

Read: 43GB/s

Latency: 46ns

 

and on 3200mhz CL14

Windows:

Read: 41GB/s

Latency: 50-54ns

 

Linux:

Read: 48GB/s

Latency 43 ns

 

It would help a lot to post your results for 8th or 9th Gen including Motherboard/BIOS version and Windows version, even if you don't know your BIOS version you could at least say that or estimate when is the last time you updated it because this isn't new it has been happening for a while now, and if it's just me who's facing this issue at least I could contact ASUS so they could test it out and confirm that it can be replicated with my exact board in Windows

Open AIDA64 and click on "Benchmark" from the icons listed, then "Memory Read" or "Memory Latency" and click "Start", try not to have anything in the background

 

Specs:

CPU: 8700K

Motherboard: ASUS Z370-A (V2401 but has been happening on many previous BIOS updates)

RAM: Hyperx Predator 2400mhz CL12

I have a couple Coffee Lake systems I can run when I get home later. As I move components around, I probably wont have directly comparable old results to compare with, but can certainly give a current result.

 

I'm also a little cautious, don't aida64 disclaim they can change how the benchmarks work between versions, so we should be a little cautious there too.

 

Edit: I found some old results in the thread below.

Say hi to security mitigations.  Enjoy your stay.

I think old results can still be comparable, at least for 3000mhz from what I've seen they mostly fall in the 43-44GB/s range for XMP profiles, there's potential for more if you tighten the timings but going down to 38GB/s is an odd deviation, your results are what I expect to see and thank you for putting the time

As I write this I listened to you and tested in v5.30 which is what I used way back when and got the same result in Linux that was using Wine to run V6.20... what..... though to note both of them can't recognize my CPU when it shows the results it says "Unknown" (My CPU wasn't released in v5.30 and because of Wine in Linux)

 

So is AIDA64 recognizing my CPU and doing something different? what the fuck? I also tested in the version you've used in your post (v5.95.4500) and again it recognizes my CPU and messes up the results, I don't get it.. I'm not sure what is detecting what to skew the results like this, it would still be helpful to see what you get though

 

2:40 Here the 9900K is performing normally too (same result for 3000mhz) but it's not known what version he used

 

Does this fall under haunted hardware?

Exists only in Windows, but not Linux?

 

prob. security shit

6.20.5300 is the current one yes, went into settings and clicked on "SMBus access through ACPI (Asus motherboards)" tested again and everything is performing normally across all versions, then I unchecked it and it still performed normally.. I've never went into settings btw and they're portable versions they don't affect each other.. what... I'm so done with this shit I don't care anymore T_T

 

Thank you for the help though, many months of tearing my hair for still no apparent reason

Did you get results more in line with the Linux ones now? Also do I take it you don't need the other system results? I haven't done them yet... food first

Yep everything seems good now I'm getting 47.3GB/s Read and 44ns Latency on 3200mhz CL14 which I'm satisfied with, still no clue why but thank you, enjoy your meal
