Mixing Memories can cause problems?

glenn585 · Feb 3, 2014

Hi guys i have a mobo that supports ddr3 (1066 max) i have installed a 2gb ram (1066) but i want to install another 2gb more but i only find 1333 on the store, it will affect performance if i install the 1333 when the other ram and the motherboard only support 1066?

Thanks in advance

There is a higher chance it may not work at all. You need two RAMS of the same Manufacturer and same frequencey (in easy terms, two RAMS in the same packet). That is best for you.

Ohh i thought if i put the 1333, it will work like a 1066

It 'might' work but I can't guarantee it. Hope that helps

Yes an no, no reason why you couldn't install the 1333mhz memory in and it should drop down to 1066 timings, if not you may need to do it manually in bios. Just ensure the memory are in matched dimm slots, to ensure no conflicts and that they all run at the same voltage.

I have a dell computer and i heard Dell locked the bios, is that true?
