Hi, i would like to know if there is a way that i can get a higher FSB for my e5200. It seems to have a wall at 330. I have tried up to 1.41 for the vcore but it still won't boot. Could i increase the northbridge voltage or something like that? Right now i have it at 325 x 11 @ 3.57 with 1.38 in the bios, 1.34 in cpu-z. i using a gigabyte ep45 ud3p with a xigmateks-1283 cooler.
here's a list of the other voltages.
CPU PLL - 1.75
CPU Termination - 1.3
CPU Reference - .76
Vcore - 1.38125
MCHCore - 1.2
MCH/DRAM Reference - .9
MCH Reference - .76
ICH i/o - 1.5
ICH Core - 1.1

i think you have hit the wall of your chip
maybe the ram is holding you back, try loosening the timings

unfortunately i think that too. I was just hoping that maybe there was something else i could do. But i do know it's not the memory that's holding it back. i had the multiplier set so that it would run in the 800 range with 5-5-5-15 timings so i know it's not the memory

I have the same CPU (E5200) with an ASUS P5QL-PRO (P43) chipset, CoolerMaster Hyper 212 cooler and with cheap RAM memory (Micron 800Mhz) and it's 100% stable at 333 x 11 @ 3.66Ghz and 1.35v in BIOS (1.33v in CPU-Z)!

btw the rest of the settings are @default values except for the memory divider which is set so that the memory would stay at 800Mhz! and also I have turned off the settings for spread spectrum and power management like Intel SpeedStep so you might want to check that also ...

also note that 333Mhz on the FSB is a standard frequancy and therefore if you leave everything at default you won't be overclocking anything on the motherboard and memory!!!

My e5200 wont go even 1mhz over fsb 330 but thats where high multiplier comes to play. I can even have it prime stable at 3.96ghz 330x12 if i pump enough voltage into it(1.56v to be precise :) 

3.6ghz requires about 1.38v but i keep it at 3.45 with 1.3v

I can also say that before i started frying it at high speed and voltage it was prime stable at 3.6 with only 1.31v Not anymore though

One of the limiting factors is going to be the VID. A lower VID is going to give you more headroom. Unfortunately, unlike the stepping, you have no idea what the VID is until you take the CPU out of the box and install it in a motherboard.
