Gigabyte EP35 DS3P BIOS settings for OC noob

Hey guys hope someone can help me.

Looking for the BIOS settings for the PCI Synchronization clock (want to make sure it is at 33mhz) and I want to make the FSB ratio 1:1 but I can't seem to find anything like that in the bios. Reading the mobo manual tells me to get the 'advanced' bios settings by clicking ctrl-f1 but still don't see those settings. Using the latest F3 bios.

Looking for these settings because I'm oc-ing a Q6600 (slacr) on the EP35-DS3P. Lots of information on here and other sites as to how to do this, but a really good post I found tells me to set the above settings (the FSB ratio to 1:1 to get better performance, and manually setting PCI clock to 33.33mhz to prevent damaging cards).

Does anyone know what settings in this board will help me here? Or should I not worry about it? So far I have tried the mobo manual and Google but I can't seem to find the info.

Thanks!

ps. 9x333 (3.0ghz) Prime95 temps for all 4 cores (after 1 hour) are approx 46-48c...so far so good it seems
 
I couldn't find a PCI clock setting, so I left that alone. Make sure you lock the PCI-Express to 100MHz though. The RAM:FSB Ratio isn't listed normally as 1:1 in Gigabyte's BIOS, the ratio should be 2.00 I believe for 1:1.You can run through the various settings and doublecheck the RAM speed listed underneath it to make sure you're hitting your target FSB rating.
 
Thanks! I did lock the PCI-E to 100mhz to protect the video card.

I'll look for the 2.00 setting. Right now my ram timings are too high (7-7-7-20 2T, 1066mhz I believe, auto settings here) and this ram ran at 4-4-4-15 2T on my last board so much more tinkering to do after I am comfortable that the cpu is doing fine.
 
DarkRogue you were right about the "2.0" setting....ram now operating 1:1 (confirmed CPUZ) at 333mhz for my 3.0ghz oc.

Still looking for info about the 'regular' PCI sync clock. If I can't find this perhaps an email to gigabyte support?

There is no regular PCI sync clock. It's always 32 or whatever the default value is.

Yeah that's what I meant when I said I couldn't find it lol, sorry.
My system is currently overclocked, and my PCI card (SB Audigy) runs fine.
