I assembled a computer that has the following components.
  • Crucial P5 2TB PCIe M.2
  • GIGABYTE Radeon RX 6500 XT GAMING OC 4G(GV-R65XTGAMING OC-4GD)
  • ASRock Z690 Phantom Gaming 4/D5 INTEL
  • Crucial DDR5 4800_32G
  • 12th Gen Intel(R) Core(TM) i9-12900KF
And then I booted into the BIOS.

Originally, the memory is "Auto" whatever that means.



If I click "XMP Profile" then it switches to Profile 1


If I click it again, now Profile 2



If I click it again, now Profile 3




Which setting is the best setting that maximizes the computation speed? I use a software that puts a 30GB of big data onto RAM and execute a heavy calculation. So it needs to be fast.

Just start with Auto to see, you can change it later when you found that your system works smoothly.
Yes I started with Auto. I have been using it in this way for a week now. But I am wondering if it will be better if I change this setting. I use a software that puts a 30GB of big data onto RAM and execute a heavy calculation. Speeding up this software is the only thing I care about.

Do you have a set of your actual data that you can use to test....using a stopwatch with the 3 different choices? The differences might not matter much, but if I was doing the same job time after time, I'd try to find out.....particularly if it was a money-making proposition.

Is there any downside of changing this setting over and over again? I am a complete beginner in computing and assembling stuff. I am worried that I might mess up something. If it doesn't cause any harm to repeatedly change this setting back and forth, then I will try and test my software like you suggested.

And if I read the BIOS in the screenshot, Profile 1 is 4800, Profile 2 is 4400, Profile 3 is 4000. Doesn't that mean that Profile 1 is the best? Then why does the computer just simply always set the setting to the best option which is Profile 1? What's the point of having the "Auto" version?
