Athlon II X-4 620 overclock to 3.0 GHz MB Gigabyte GA-MA74GM-S2

Under: Dram Configuration I chose Manual
I got the
DDr2 Voltage Control set to 1.900 v.
Now i have: Northbridge Volt control [normal]
Southbridge Volt Control [Normal]
CPU NB VID Control [Normal}
CPU Voltage Control [Normal]

I tried change the memory settings and could not boot.

Memory Clock says 920Mhz 1225Mhz, Shouldn't that be 1066Mhz

My Memory is DDR2 Patriot Gseries Extreme Performance PC2-6400 800MHz

My Dram Timing Control doesn't seem right. Memory package says 5-5-5-15
The bios says 5-5-5-12
