XMP does not work

 Share

So I bought a MSI B250 Pc Mate Pro Series ATX motherboard recently. From everything I've read in the manual and on the box the board is rated for memory up to 2400mhz.

 

So I paired the board with an i7 6700 and 16 gb of corsair vengeance 2400mhz DDR4 that was certified for Intel chip sets and core I Intel CPUs. And tired enabling the XMP only to see no charge on reboot. 

 

Upon further inspection of the manual I notice a little tiny blurb that says 2133mhz on 6th gen CPUs and up to 2400mhz on 7th gen CPUs. 

 

I previously read an article that stataed ram speeds were not dependant on cpu but we're dependant on motherboard ratings and compatibility so I never expected a motherboard rated for 2400mhz ram to need a specific gen of cpu to achieve those speeds. 

 

Is this a chipset limitation,  a bios limitation, a limitation of the locked cpu, or just a limitation of 6th gen chips? 

 

Also not sure if it's important or not but my ram shows as unknown in the bios and in specy is this a common thing and is it an issue?

If the platform doesnt support overclocking, it's limited by the component with the lowest standards.

Yea well .. the cpu should at least be in the area of the xmp speed.... I never could get it working on a first gen i7 with asus board... if i turned on the xmp profile there it would boot but it worked very slow, the board btw did support speeds up to 2000 mhz, the memory was 1600 xmp and the cpu did 1333 mhz … funny thing was setting speed manually made 1600 mhz workable … highest i went was 1750 

anyway with my new system it works fine, xmp that is but both motherboard and cpu are granted for the 3000 mhz .. currently i'm using it at 3 ghz but without xmp .. i really don't need the ocing of various clocks etc

So basically because it's a B250 instead of a z250 motherboard I'm limited to the base ram clock of 2133mhz set to the i7 6700 where as the i7 7700 has a base ram clock speed of 2400mhz?

 

So if I was using a z150 or z250 would I be able to run the faster ram even with the locked 6700,  or would I also need to be using a 6700k in order to get speeds higher than the base ram speeds of the cpu?

only z170 and z270

 

memory OC on Intel doesnt care about the CPU, just the board.

So if I understand correctly if it's not a z chipset board the cpu is the limitation as the CPUs memory controller sets the ram speed but on a z chipset it's dependant on the capabilities of the boards memory controler for how fast you can run ram?

no it's product segmentation. Intel wants you to spend money. the 6700's memory controller is exactly the same as 6700k's. Heck, because of how it's made even the 6400T has the same memory controller.

Non oc boards, the ram runs at, the ram speed set by the cpu. So your i7 6700 supporting only up to 2133 mhz. Then your ram, no matter how fast it is, will only run at 2133MHz. To run your memory higher than 2133MHz with your i7 6700, you will need a oc board like a z170 or z270. There is no need for a 6700K just so the ram can run beyond the limit, set by your cpu.

I think you misunderstood what I meant I get the whole basis of locked and unlocked versions. What I was implying was that any 6000 series cpu would only run at 2133mhz on a B250 board weather it be a 6700 or a 6700k or a 6500..... Where as a 7700 or a 7700k would run ram at 2400mhz making the cpu the limitation but if it was in a z170 or z270 all of the above CPUs can be run with ram that's faster.
