How to use 680i overclocking feature set?

Nvidia's 680i chipset supports auto overclocking on memory and PCI-E bus if you have the correct equipment, but I'm not entirely clear how these get activated? Is it obvious in the BIOS? I'm looking at Asus's boards and they have their own overclocking techniques so I'm not sure how the Nvidia stuff gets activated as opposed to Asus's stuff.
 
Can't comment on the Asus boards, but on the EVGA/Nvidia board its done automatically. The PCI-E is called "Linkboost", and it will enable automatically and turn green if you have an approved mobo/GFX card combo. This basically adds 25(I think) to the PCI-E bus that the card is installed in. The Memory is called "SLI Ready Memory", same deal, says enabled and turns green if you have Nvidia blessed memory. From what I can see, this just tightens the timings of the memory up a bit in expert mode, and enables the ability to do an "auto overclock" for the CPU/Memory if linked.

Not by any means an expert though, I run both "features" disabled.
 
The memory I have (Corsair XMS2 PC-6400C4) is considered SLI Ready Memory (EPP), but my motherboard (P5N32-E SLI) did not automatically detect that and overclock it. I had to manually turn it on in the BIOS to use the faster memory timings.
 
Mometary thread burp;

Yreka, you're running the same mb/ram/cpu I'm about to set up. How do you like it and did you have any issues?

Yes please give details on what worked for you. I also have the same CPU/Mem/MB combo. Only have a single 8800 GTX installed at the moment. Its in a Silverstone TJ06 case with the Zalman 9700 cooler.
I have yet to attempt overclocking yet till I know for sure my SATA issues are resolved.
I'm not looking for a 4.0 overclock like you WOW!! I think I would be happy at 3.4

PS: The 3.2 OC in my rig specs below was what I attempted when I first got the board a week ago. I had SATA Issues and left it at stock for the moment.
 
I have my E6600 OCed to 3.4 GHZ stable. Temp idles at 43 degrees and maxes out at 63 according to Core Temp. I also have my 667 MHZ OCZ Ram running at 800 MHZ.

In the Asus bios, go to Extreme Tweaking and set it to Manual. You then go into the FSB and Memory speed selection and make manual changes. For best memory performance, find out what the timings are and manually enter those in the memory timings before tweaking.
