The general concepts of OC are the same.
Start out by setting the RAM ratio to the LOWEST value. Then gradually increase the bclk while closely monitoring the temps and voltages. Do not exceed the manufacturer's recommendations.
After a stable desired OC is achieved, check the RAM ratio and adjust accordingly. It's ok to run the RAM slightly underclocked.
Here are my settings (i7-920, 12 GBs of Dominator RAM)
3.82 GHz - 1.275 volts - temp 30 degs C
1600 MHz RAM set to 1452 MHz - 1.550 volts 9-9-9-24
Motherboard - EVGA Classified 3-way - http://www.newegg.com/Product/Product.aspx?Item=N82E16813188048&cm_re=EVGA_motherboards-_-13-188-048-_-Product
Please keep in mind that each set of CPU/motherboard will work differently.
I solved stability problems by raising the CPU voltage slightly - to 1.275 volts (max permissible is 1.375 volts)
