Nvidia chipsets do not use the bus speed to overclock, but the QDR (FSB) or quad pumped bus speed.

Hence your cpu E4700 has a FSB of 800, meaning it is 200mhz bus speed x 4. Your CPU multi is 13, 200 x 13 = 2.6ghz.

To overclock your CPU, you need to adjust the QDR from 800 on up.

You only need to change two settings. First set the BIOS to default. Then:

1. Unlocked the memory clock mode

2. Set your FSB to 1066

Leave everything else on Auto and you should post at 3.45 GHz!

If you want to go higher you'll need something like Artic Cooling Freezer 7 Pro.

Try 1.28 volts or 1.29. Disable EIST and C1E.
You'll know right away (5 minutes?) with Prime 05 blend test if it isn't stable to go for an overnight test.

Don't go past 1.325 volts.
