ep43-ds3 and 4G memory

[sonax04]

Hi
I am looking for some advise and help with this build
GA-EP43DS3 Bios F9
Intel E7500 2.93GHz
Kingston 4x KVR1066D2N7/1G
Inno3d geforce 9800gt 512mb ddr3
Seagate ST3160813AS
Antec Neo HE550

I have played with the setting for 2g and system seem to run fine in duel channel but as soon as i put the other 2g in system keeps on rebooting i have swaped memory around and run mem test with no errors so i believe i still need to change some more setting or start again but this is where i am stuck so need some help
Many thanks
