i want to ask that will these work fine with my existing ram, someone told me it can be a compatibility issue even they are from same brand and same specifications. he advised me to sell old and buy 2 x 4gb instead.
Gigabyte P55 MB.
Bought 4 Kits (2 per kit) modules over the course of a year. all were Ripjaw DDR3 -1600 @ 1.6 V. The 2 kits 2 x 2 were listed as Cl 7,7,7, the 2 Kits (2 x 4) were listed as Cl 7,8,7.
I went from 2 x 2 -> 4 x 2 -> 2 x 4 -> 4 x 4. DID NOT intermix kits - kept matched pairs together. All above combinations were stable (Used Prime 95 to test). When using the CL 7,8,7 with the CL 7,7,7 - I used the 7,8,7 in the Primary slots., Maybe I was lucky.
