Bios safe mode while Overclocking E6600 on an EVGA 680i SLI board

[cyburtis]

I've recently begun overclocking my new system following this guide:
Link from IGN website

and info in this post:
Anandtech post

I'm using a ARCTIC COOLING Freezer 7 Pro 92mm CPU Cooler.

Using TAT I see my temps are around 30c idle and 40c under load from SP2004 Orthos
With voltages at :
CPU Core: 1.45V
CPU FSB: 1.5V
nForce SPP: 1.50V

I can't seem to get the FSB past 1300 MHz resulting in around a 2.9MHz result. What happens is during the POST I get a message saying that your computer is now in safe mode (Not windows safe mode as if it had blue screened.) Please change your frequencies and voltages in advanced chipset features. F1 to continue or enter setup. If I continue with F1 it goes into windows with stock settings. (no OC)

Does this mean that I need to alter another setting (voltage?) if I want to get higher? It just seems that I should be able to get better results than this.

Any help or direction would be appreciated!

Have you turned off E1ST, EPP, and all of that crap? If not, that's your problem, assuming you're using PC6400 RAM. If you're using PC5300 RAM, you'll have to raise your timings, and you still may not get it any higher, assuming you're running it 1:1.

edit: You aren't trying to run to run your RAM with a 1T command rate, are you? If so, relax that to 2T; it will be able to go considerably higher.

It is PC6400 RAM I'm using. (Patriot eXtreme Performance 2GB) I thought for sure that I did have it unlinked (and all the misc stuff disabled as well) but I'll have to double check when I get outta work - since that seems to be the most common response. I'l also going to have to spend some more time with my nose in the memory section of Nvidia's overclocking guide. Hadn't originally intended to mess with the memory settings..but it seems to be more closely tied that I had thought. Thankts and I'll post when I learn more.

I did indeed have all of those things disabled and set properly per the guide. It seems that I had one of those FSB holes I've read about. I turned the FSB up right past my sticking point into a 3.0 and it worked fine. I went from there and have settled on a 3.2 and she's been running cool and stable since. I'll run a 12 hour stress test overnight tonight..but I'm pretty sure I'm good to go.
Thanks for your input.
