Hi everone, I own Gigabyte GA-8N SLI rev1.1 which is Nforce SLI chipset that support up to 1066FSB.
I equip this board with Pentium D 915 which run at 800FSB. When I overclock above 900FSB, it will no post. But if I put above 1033FSB, it is will post but will restart everytime. (Means not stable at all).
I already set all setting other than CPU to default frequency. Example, I fix the PCIE clock at 100mhz, DDR2 RAM at 533mhz. And one thing I am sure that is this Pentium D 915 can run above 1066FSB. I have been try a lot of setting and still failed.
I just suspected it is Gigabyte GA-8N SLI rev1.1 is not overclockable. Or what mistake I done with this overclocking. Anyone with this board success to overclocking? Or have the idea? Pls guide me. Thanks a lot!

Below is my spec:
Gigabyte GA-8N SLI rev1.1
Pentium D 915 (2.8G,800FSB)
Geforce 6600GT
Kingston 512MB DDR2 533mhz * 2
Seagate 250GB SATA2

Mine one is Icute 450watt power supply
