Problem with Quad machine


I recently bought Quad machine but my processes gets killed because of segmentation faults. I am also facing memory errors. What should I do?

pagesize is 4096
pagesizemask is 0xfffffffffffff000
want 1024MB (1073741824 bytes)
got 1024MB (1073741824 bytes), trying mlock …locked.

Here is the output of dmesg for segmentation faults:

Hi, what CPU do you have?
