Question memory support

[wajdihssen]

hello guys , sorry about my english , i have a pc with asrock h81 DGS r2.0 , i5 4570 , 6 gb ram pc3-10600 frequency .. when i decide to upgrade to 8 ram , I've looked at which memory frequence i cant buy , so my mother board in the site of asrock accept almost all frequency 1333/1600 ..... and my cpu to accepte all this frequence , i buy a ram 4 gb with 1600 mhz and another ram with 1066 and another 1866 no one of this ram work in my pc , black screen or message with cpu is not compatible with ... I am wondering if my motherboard and cpu is compatible only with the 10600 frequency or what is the problem ? .. Knowing that I change the memory bios setting to auto and 1600 and i test all of them and my biost version is the latest version

Mixing an adding memory is hit and miss even if identical. Best if purchased in a matching set. 1600 is what I would go with. But buy as a pair.

The brand you have of 1600Mhz is probably not compatible Crucial compatible https://www.crucial.com/usa/en/compatible-upgrade-for/ASRock/h81m-dgs-r2*0

The memory has to be made compatible with your mother board! All DDR3 is not the same.
