2x4gb and 1x8gb or 4x4gb?

[dmitrip0rnstar]

which performs better?

 

[marksavio]

depends on your board. and definitely the 1x8Gb is the least effective.

if your mobo supports only Dual Channel, might go for 2x8gb, than 2x4gb + 1x8gb, it might disables the dual-channel
if your mobo supports Quad Channel, might go for 4x4gb,
either way, difference in performace is little to none
and as stated above, 1x8gb is the least effective
