Fake RAM timings in Alienware Command Center?

Dell G15 5515 Ryzen Edition has 4ATF1G64HZ-3G2E2 from Micron Technology and is an x16 (the worst one possible). Now the problem is the RAM timings. Every tool shows it to be timed at 22-22-22-52. But Dell's own software Alienware Command Center shows it to be timed at 17-17-17-39. What is going on?

So, 17-17-17-39 is a standardized timing for DDR4 memory—but, it's typically associated with DDR4-2400.

I've got an older G5 SE laptop—but like your G15, I've got DDR4-3200 memory installed from the factory. Note that the memory that came from the factory in my G5 does report 17-17-17-39 as a supported memory timing.

It's possible that AWCC is showing you the memory timing parameters for a sub-timing of your DDR4-3200 memory modules…

Since ZenTimings and CPU-Z both report that your primary memory timings are operating at 22-22-22-52, IMHO you've found a bug in how AWCC reports memory timing info for the G15 Ryzen Edition.

I agree with you.

If they want to show the best number, should have chosen 10-10-10-22 because that's also supported by my RAM, but then everyone can instantly catch their lie. So they choses a reasonable number 17-17-17-39!!!

I'm laughing here. We would have seen 3200 MHz with 10-10-10-22 timings if Dell wants its way!

Let's hope for an update by Dell to fix this to represent the actual RAM timings.

IMHO, DDR4-3200 running at CL10 is too good to be true. The best XMP profile I've personally seen for DDR4-3200 memory modules is 14-16-16-34.

Totally—this seems like AWCC is reading the wrong entry from the memory's Serial Presence Detect (SPD) table.

Yes, fully agree with you. By the phrase "Dell wants its way!", I meant, whatever fake number Dell wants to show including fictional. CL10 is also supported by that RAM as per SPD table but obviously not for 3200MHz. CL10 for 2 x 666.7MHz. The best CL from SPD table and the max frequency of the RAM is what Dell would have shown even though that does not make sense.
