AsRock Z87 Extreme4 UEFI doesn't recognize correct RAM timings. Must I overclock?

Hi, I'm having a little confusion over how the UEFI on my AsRock Z87 Extreme4 motherboard interprets my RAM. I use two 4GB sticks of G.SKILL Ripjaws RAM at 1866. (G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866) And its timings are listed as 8-9-9-24.

My motherboard supports up to 1600, 1866 (O.C.). , so I guess it makes sense that I would have to do some overclocking to run my RAM's native speed. However, in settings the UEFI lists the RAM's timings as 11-11-11-28 instead of its actual timings. Does this mean that I also have to overclock my CPU to attain these speeds? Or is this perhaps just an UEFI error and I can just run the correct times?

Thanks in advance.

Did you set the XMP profile?

That's correct. It will not run your memory at DDR3-1866 automatically, you must enable the XMP profile. It may also be necessary to tweak the IMC voltage a bit too

The XMP profile definitely does show the correct settings, but whenever I select XMP profiles 1 or 2 and I look at advanced settings, those very same timing speeds show up. Does this mean that enabling the XMP profile requires me to overclock?

What I meant by "correct settings": The option is listed as "XMP Profile 1 DDR3-1866 8-9-9-24 1.50W"

Yes, that's exactly what it does. XMP profiles are non-standard (non-JEDEC) profiles which feature higher bus speeds, tighter timings, and higher voltage levels. The only difference between entering those numbers by hand into the relevant fields and enabling an XMP profile is that the XMP profile sets them automatically. You will of course have to reboot for them to take effect.

Thank you. I used the XMP Profile and rebooted. Now it says DRAM Frequency: 1866 (1:7) and the Advanced Settings say 8-9-9-24. Now that it's set correctly do I need to do anything to other settings given my RAM's 1866 speed and my mobo only supporting up to 1600. (From Newegg: 2933+(OC)/2800(OC)/2400(OC)/2133(OC)/1866(OC)/1600/1333/1066)

(And on a tangential note about the UEFI, I also accidentally clicked Secure Backup UEFI, which triggered this automatic process I couldn't cancel. The manual says "Whenever one of the ROM images are corrupted or outdated, switch to the other flash ROM and execute Secure Backup UEFI to duplicate the current working ROM image to the secondary flash ROM. Since I never used another UEFI ROM, can I safely say that I didn't accidentally create a back up of it on say, my SSD?)

I don't know anything about Secure Backup, but as far as the XMP profile goes you're done. Keep an eye out for unexpected freezes and BSODs. If you do experience some, consider bumping the IMC voltage up a little bit. If you don't experience any, then you're good to go!

Hello,
Where is the XMP profile? I didn't see it anywhere.
