I'm using two of this: OCZ3P1333LVAM4GK (OCZ DDR3 AMD Edition, rated for 1333MHz at 1.65V). My Board is rated for 1066 - 1600 MHz memory, and neither the website nor the manual say anything about limitations with memory. Anyway: I didn't overclock cpu or memory. I have stability and long life in mind, so I try to keep the hardware cool. During testing I underclocked the memory with 1066 and 800 MHz which didn't help: The machine crashes anyway. The only thing to note is that by default the board tries to set 1.5V DDR3 Voltage which is wrong, you have to set it to 1.65V manually. A faulty piece of hardware was the first thing I suspected and I tested among other things the memory with memtest86+. This runs fine for 4 passes, without any error. As far as I can tell, my memory subsystem is ok. As for make.conf: thanks, I will set this when I try again. with best regards Sven -- 00
