Begginner xmp question...

[zer]

Merry Christmas everyone from Greece!
Recently i built a new system compiled from old and new staff: i7 9700K, Asrock H370 HDV mobo, RTX 3070 an 16Gb DDR4 Ram 3600CL16. Motherboard doesnt support overclocking the CPU and only supports memory up to 2666. Right now i havent enabled XMP, so RAM runs at 2133 or sthing, the lowest anyway.
Question is , do i enable XMP from BIOS? Will it use a Profile @ 2666 CL16, or try to run @ 3600, probably can't since its not supported and then fail to boot? Should i choose an "AUTO" option or manualy select 2666?
Many , many thanks!

Are you sure you're not already running at 2666? What does windows say your ram speed is? Task manager should tell you under memory. If not....

Depending on your ram it probably have alternative settings for 2666 mhz but you'll likely need to pick them manually.... I know my ddr4 ram does.

Look in the bios and see what options are available for the ram, you're usually looking for 'xmp' or 'jedec' depending on the bios.

Thanks,
Task Manager says 2133, so does CPU-Z...So, i should enter bios and try to to select 2666 under some Manual adjustment, right? Not "just" enable Profile 1" for example, because it may try to run memory at "native" 3600, then crash since mobo only goes upto 2666? Do i understand it correctly?

Yes 2666mhz is the max.

But if you select profile 1 you should see what memory speed it selects if its 2666mhz then all good but any higher then it won't work.

Remember if you select profile 1 you don't have to keep it at that if its to high you can exit the bios without saving then go back into it bios again.
