Theres people (including AT at their review) that can hit 500fsb on the Gigabyte 965P-DS3, mine wont do over 350 without losing stability, even with cranked vFSB.
I had a DS3 P965 chipset board Revision 1.0 overclocked to 425FSB. These are some of the settings I've adjusted after I replaced the northbridge heatsink with
Zalman NB47J and AC3.
Part 1: Tweaking the BIOS
1) Disable CIA 2
2) Set PCI Express to 100mhz (some users recommend Auto for DS3/DS4 and DQ6)
3) Set PCI frequency to 33mhz
4) Disable any speed spectrum
5) Disable 'Limit CPUID Max to 3'
6) Disable any voltage protection
7) Disable 'C1E'
8) Disable 'EIST'
9) Disable Virtualization Technology
10) Disable No Execute Memory Protect
11) Disably any other things you dont use like IDE ports if not using
12) Do not enable any speed enhancements you see
Part 2: Tweaking the voltage
1. Set MCH Voltage (vMCH) to 1.50-1.55V (only if overclocking past 400FSB) - If I recall this is +0.2V
2. Set FSB voltage (vFSB) to 1.40V (If I recall this is increased by +0.1V)
3. Increase SB Voltage by +0.1V from default.
This overclock worked perfectly fine with BIOSes F7 to F9. After that I sold the board so cannot testify to the more current versions.
