Memory compatible Need help please

[Catalin_2]

Hello all of you and good day i have a simple question if anyone can help me . Current i have a 4GB memory Kingstone model(kingstone kvr1333d3n9/4g) here is the producer information for this type of memory http://www.kingston.com/datasheets/kvr1333d3n9_4g.pdf IT says CL 9 And latency 9 8 7 6 and i wanna buy 4 more GB ram but i wanna buy this model Kingston HyperX Fury Black Series DDR3, 1x4GB, 1333 MHz but on this one the CL is the same 9 but on Latencty it say 9-9-9-27 and the frecvency is the same 1333 it would be a problem for compatibily to make 8 GB total of ram thank you

It's hard to say without it being in your system. But generally it is advised against mixing two different models of RAM with different latencies. If you can, I 'd recommend buying a new kit of 2x4GB. However, if this is not possible due to budget constraints then you can give it ago. I can't guarantee it but people have gotten these kinds of combinations to work, it may require some manual tweaking of settings.

well they have bouth Frecvency 1333Mhz and have CL9

That is irrelevant as the manufacturing process behind RAM from different manufacturers is different. Different DIMMs can use different types of circuit boards and solders giving the DIMM different properties such as conductivity meaning sometimes it won't play well with other types of RAM

Mixing DRAM from different packages can be an often is problematic, more on it in my article (Fiction, Item 2) here:
