Memory products with a frequency of 3000MHZ and higher than 3000mhz , which are not using the J.E.D.E.C. standard, which are with the X.M.P. standard. Please check whether the motherboard and CPU support X.M.P. before purchasing.

If the motherboard and CPU don’t support the change standard, the memory will can  only work at 2666MHZ/2400MHZ.In addition, due to the CPU and motherboard’s problems, for 3000MHz and above frequency 3000mhz memory, if you two pieces single channel memory or four combinations together , it may not be able to form a two-channel or multi-channel, without the original manufacture’s test, you can mix and match personally , there may be mismatch and can’t work in right way .
