Ok, I have tried both stick individually and both by themselves have rebooted the system.
I have messed with the timing and set the CAS Latency to 3 and some other things to keep the machine stable but it still reboots but the PC lasts a bit longer.
I really don't understand much about RAM timing so here is what my motherboard has in the BIOS to see if I can get further assistance.
These are all default or "By Spd"
DRAM CAS Latency [2.5] (I have to choose from 1.5, 2, 2.5, 3)
Bank Interleave [ Disabled] (I have to choose from Disabled, 2 Bank, 4 Bank)
Precharge to Active (Trp) [5T] (I have to choose from 2T, 3T, 4T, 5T)
Active to Precharge (Tras) [7T] (I have to choose from 6T, 7T, 8T, 9T)
Active to CMD (Trcd) [5T] (I have to choose from 2T, 3T, 4T, 5T)
DRAM Burst Length [4] (I have to choose from 4, 8)
DRAM Command Rate [2T] (I have to choose from 2T Command, 1T Command)
Hopefully you guys can help me make sense of this, I will be running memtest on each stick now so I might not be on.
I also got the PC to last longer this time so I can post this with the CAS Latency at 3... bank interleave at 4 bank, Precharge to Active at 4 and Active to CMD at 4 I think...
