Resolved Geekbench 5 - RAM shows only 1200 MHz

[nihil0]

So I downloaded Geekbench 5 yesterday and after results uploaded I was surprised to see that it shows my RAM as only 1200 MHz

https://browser.geekbench.com/v5/cpu/23383

Could this be only some Geekbench error? Because when I see RAM info in System Information, it shows all 4 modules as 2400 MHz. I have stock 8 GB RAM and 2x 8 GB RAM from Corsair Vengeance (DDR4 SDRAM 2400 MHz CL16).

However, when compared to identical model with 16 GB RAM, I have lower score (https://browser.geekbench.com/v5/cpu/25157)

The "DDR" in DDR4 stands for "double data rate".
Your 2400 MHz RAM runs at a clock frequency of 1200 MHz, but since it's "double data rate", it performs 2400 Million transfers per second.

Here's more info: https://en.wikipedia.org/wiki/Double_data_rate

I agree it's confusing of Geekbench not to use the more standard 2400 Mhz value.

As for the score difference with the identical model: seems like the usual variance ... different ambient temperature, other tasks running in the background, etc.
Also, RAM frequency is not the only determining factor. Your memory has a latency of CL16, while the other system might use memory with a lower latency, things like that ...

Thanks for the explanation
