F2-8500CL5D-2GBPK x 4 No Boot

[thwebs]

I was running 2 - 1 G sticks with no issues, then I added 2 more of the same and system wont boot. BIO's shows them at 1796Meg???

I removed the old ones and placed the new ones in and it works fine. How do I get all 4 to work together?

Do I need to adjust my voltages or is this a power supply issue?

Below quote was from New Egg X forum, first one I tried with no success,

Make usre the memories voltages are set to 2.1v and the timings are set to 5-5-5-15 and that the command rate is set to 2T.

I have not tried this yet, not sure I believe this one:
If that doesn't work then set the speed to 800MHz the voltage to 1.8v and the timings to 5-5-5-18 because your main board only supports two sticks of DDR2 1066 RAM ..... or buy 2 2GB sticks of DDR2 1066 RAM.
