[SOLVED] Question about RAM speed

[nicholas70]

I recently upgraded my system with MSI MAG Tomahawk Z390 and I7 9700K , and to my surprise my RAM did not start running at 2666mzh as I was under the impression it was supposed to do with the I7 I had purchased. Later when I was in the bios I decided to enable XMP just to see what would happen and sure enough the memory started running at 2666mzh. I ran with it like this for no more then 5 or 6 min and decided to go back and turn xmp off as I've been troubleshooting a gaming issue I have been having and didn't want a new setting possibly complicating my troubleshooting efforts.

First I want to know if it is possible that by enabling XMP for this short period of time that I might have damaged something. I would also like to add that I was not overclocking anything else on the system at the time XMP was enabled.

My second question is why am I having to use an overclocking feature to achieve memory speeds listed as spec on intels data sheet for this processor. It is also the specified speed for the DDR4 memory I'm using, and is a speed listed on MSI's website for this mobo as being within spec(not OC)

And finally given these memory speeds are listed as 'within spec' by MSI and Intel is there any risk to me running XMP to achieve this memory speed? Could my system become unstable or would I void any warranties as I'm 'technically' having to use an overclocking feature to get those speeds?

Also memory I'm running is Corsair Vengeance LPX 2x8GB 2666

DDR4 starts at 2133MHz so anything over that is considered overclocking it, using XMP (profile is stored in RAM's controller chip) BIOS just reads it and sets parameters accordingly, it wouldn't be possible if they thought it was unsafe. Run RAM checks though, I recently had a pair of same RAM of which one was throwing errors.
