My system:
Gigabyte GA-MA770-UD3
Athlon 64 X2 5600+ Brisbane
G.Skill F2-8500CL5D 2x2GB (4GB total)
Sapphire Radeon HD 4830 512mb
Raidmax 450 watt power supply
Memory runs at 800 and not 1066 which I’m fine with, since that’s apparently a limitation of my CPU. The problem is when I have both sticks of the G.Skill memory installed, my machine using XP SP3 will randomly reboot.
Running the latest version of MemTest86, the machine reboots right after the test starts if both sticks are installed. If only one stick is installed, MemTest runs fine. I tested each stick on it’s own, and the reboot only happens when both sticks are installed.
I tried both sticks in different memory slots, and the reboots happen regardless of whether the memory runs at dual or single channel. I have verified the CAS settings of 5-5-5-15 are correctly set in the bios.
Two old sticks of 533 DDR2 run fine in dual channel and pass MemTest86.
My thoughts are possibly the power supply is inadequate, since one stick of the G.Skill memory works fine, but two are unstable. The older 533 DDR2 memory is a lower voltage of 1.8v, and two sticks of that work fine. Unfortunately I don’t have a higher wattage power supply to test this theory.
Any suggestions? Thanks.
