First post, second overclock... and I need some help please.
First off I read all the related guides I could find, and did as advised, yet I still ran in to problems.
Issue: Can't boost FSB higher than 340 MHZ no matter the settings, by doing so, I can't boot windows (xp pro). If I go higher, the windows load screen hangs, and then the system restarts. I have version f4 of the bios.
My settings are as follows:
C1E and EIST -disabled
C.I.A.2-disabled
PCI-e freq @ 100 MHZ
Performance Enhance - standard
During my testing I have concluded that RAM settings (divider, voltage, mhz) have no effect, so the problem is not here.
I have gone up to as much as 1.35 with Vcore, +.2 at FSB, MCH and PCI-e Overvoltage, and have tried different combinations. The result is the same alway: I can't boot windows if my FSB is higher than 340.
I have read from many people how they took the overclocking lot further, I just can't see how. Any help would be appreciated! Thanks!

I put together a build for a friend just like yours. P35 DS3L and e7200. For some reason it wasn't stable even at 3.2ghz. I didn't really get a good chance to mess around with it enough to fine tune it. I would turn the multiplier down to 8..ran divider 1:1...FSB 400 and your chipset voltages seem fine. I would definitely start at lower clocks and build up instead of jumping up to 400 right away. Once again, try a lower multiplier. My FSB is at 450MHz rock solid for the past 8 months so you shouldn't be hitting a FSB wall at a very modest 340MHz

always update to the latest BIOS and select 1:1 multiplier and 5-5-5-18 timing and change ram voltage to 2.1V.if cant get higher on the FSB try to skip FSB straigh to 375.and try to lower multiplier if cant boot
My EP35 is also very picky, one random thing that I noticed to disable was the fan control (SMART fan or something like that in the BIOS), it pumps up the fan speed when your cpu is working hard and slows it down when its idle to save power, I found if I disable it I get more successful boot ups through the bios (rather then restarting after the bios screen flashes up). No idea why this happens, doesn't really make sense, but when I disable it the fans run at full power 24/7, so it can't hurt the systems cooling potential, only the electric bill.
Another thing to consider is how your CPU fan is plugged into the MOBO, if you are using a controller it can cause funky boot ups, I ended ditching my zelman speed controller connector and plugged it into a extra fan power switch, so it just ran full speed no matter what the MOBO tried to tell it.
