Hi All,

My current system configuration is
i5 4440
GA-H97M-D3H
1 Kingston Hyper X Blu (9-9-9-28) , 1600, 1.5v (Not using the XMP profile)

Can I mix it with the following RAM (I understand the RAM will need to run slower and incur a penalty hit)

Kingston FURY 8 GB (10-10/11-10-30), 1866 , 1.5v

OR

Kingston FURY 4 GB (10-10/11-10-30), 1866 , 1.5v

Thanks

Even if you buy the exact same modules (same P/N) on two different occasions, it's not guaranteed to work. This can happen with the manufacturer can't source the same RAM IC's in later runs. Quite often the manufacturer will switch RAM IC's (BGA memory chips) to something that is available and it may not even be the same memory maker. Since the memory packages are more or less standard size and the pinouts are usually the same, the manufacturer can often put different BGA's on the same PCB. They will keep the P/N the same in some cases and sell them as the same as previous runs. However since the physical RAM IC's are different, they may not play nicely with DIMM's of the same P/N from different runs.
Maybe, no way to say for sure. Only way to find out is to try it. Like said above, ram should be purchased together in the same pack for assured compatibility. Even ram from the same vendor with the same exact specs on occasion wont play well together.
