Dual chanel magically started working

[_Rici_]

Hi. Can someone explain this?

So dual chanel on my HP Prodesk 600 g1 was not working for some time. Until i repasted the processor today. I lifted the processor if there were any bent pins, dust, etc.. Everything was allright. So i pasted it and started it up. I didn't want to even start in singlechanel. I didn't know what to do. I lifted the proccesor from the socket again, blew onto the pins and... It worked ! Dualchanel is working ! Can somebody explain this ?

Hi @_Rici_ 

The only conclusion I have is the memory controller is in the CPU.

Dirt or dust on the CPU pads related to memory function?

Probably yes. But there was nothing wisible...
