Intel XMP and Semi-Identical RAM

I'm switching from AMD to Intel (and because AMD doesn't have special memory profiles this wasn't an issue) I have these two sets of memory kits which are identical besides one supporting XMP

Will it cause any issues with the i7-4790k? and can I enable XMP on the kit that doesn't have it IF they are identical?

Honestly if it's gonna cause issues I'll probably just bite the bullet, sell the kits and get a 6700k (I REALLY don't want to though)

Thanks guys, in advance!

XMP speed, timing and voltage are read from only the stick that is closest to the memory controller (ie. the CPU) and those parameters are applied to all the memory.

But, thinking that you have two sets of exactly matching memory (XMP aside) is foolhardy.

JEDEC: DDR3-1600 CL11-11-11 @1.5V ,XMP Profile #1: D3-1600 CL9-9-9 @1.65V only tells you about three timings, there asr actually more thgan 20.

You can download RamMon and check many other parameters.

Thank you for this information. biggrin.gif

Interestingly enough the program you've linked me to seems to show what I thought (unless I'm not looking in the right place) all of the information besides the Manufactured Date and the Module Serial # is identical. Is that because of what you said, values are copied from the closest stick to all or something else?

No, it's reading all the sticks individually. Looks like you have a match.
