For all the 680i user out there I have a question; Once I get teh FSB past 1066MHz the FSB voltage increase along with the HT nforce voltage which I think is the PCIe voltage.

Do I necessarily need to increase any of the other voltages if I am only overclock my CPU? These are as followsin the 680i BIOS:

CPU FSB
nforce SPP
nforce MCP
and
HT force


I find it quite odd that the HT force/PCIe voltage increase also.

What board? EVGA?BFG?ECS?ASUS?

If the settings are there..they are definatly all there for a reason!

Typicaly though, when overclocking any board, there is a reasonable amount of headroom before you have to touch any of those voltages.

Often you can reach a 15-30% OC before having to raise any voltages on anything , and that is usually the case for most CPU's. With the low end Intel Core 2 Duo's, often a 40% or more OC can be had at stock voltage!

My 1.8GHZ E4300 would run at 2.7GHZ with stock voltage, for a 900MHZ gain (50%OC) where as my E6600 would run 3GHZ with the stock voltage, a 600MHZ gain (25%OC)

Without getting into specifics, push your OC as far as you can go stock and test for stability using ORTHOS (In my Ultimate links collection at the bottom of my sig), then try raising the voltages one at a time (Put it back to stock if it doesn't help stability, until you narrow it down to the setting that does..often it will take a combo of them to produce a stable setting.

Planet may be able to hook you up with some specific settings that are known to work....these are just general OC guidelines.

One last thing, for daily use, most DDR-2 should not be set above 2.0-2.2v, only a few modules out there are warrantied to live at 2.3-2.4v, and you only see a small gain in the OC above 2.2v in most cases anyways, hardly worth it unless you are a benchmark junkie who upgrades every 6 months or less!

Thx for the advice.

eVGA 680i-SLI A1 revision with a E4300.

Typical OC's for the E4300's are in the 3.2-3.4GHZ range with a decent aftermarket air cooler, using 1.45-1.6v..I was able to only get 3.2GHZ from mine daily use, it struggled to get aove 3.4GHZ for benchmarking only.

Coel has one he just OC'd that you might find of intrest.
