Need help getting past 330 FSB

I just installed a side 120mm fan so i decided to see what i could OC on my biostar 965pt, e6400 and 2x1gb gskill pc6400.
I managed to get my FSB up to 330 at stock voltage, with memory speed and timing on 'auto'. My computer is running cool at 36c and I'd like to get it up to 3ghz possibly.

I know to achieve this i would have to set my FSB:RAM ration to 1:1, but whenever i try to manually set my ram speed with an OC my system refuses to POST. Today when i tried to set FSB to 400 and Ram speed to 800 my monitor never received a signal and the computer just defaulted back after restarting.
When i set the ram to 667 and my FSB to 333 the system turned on but just froze when detecting IDE drives so i had to reset the CMOS.
I would appreciate any help regarding the subject and how i could set my FSB:RAM ratio to 1:1 to get at least 3ghz.
 
Look at you right side display in CPU-Z you are running the memory at 496 MHz which is way too high. Keep it at 1:1 for the E6400.

That means manually set the memory clock ratio to 2.0 in your BIOS.

The good news is your memory will hit 500 MHz which is a lot faster than what mine will :D

The BUS SPEED setting in your left panel 330 should match the FREQUENCY in your memory timings panel of CPU-Z.

The FSB:DRAM display should read 1:1 You do not want the DRAM # to be greater than the FSB number they should be exactly 1:1
 
I'm using a biostar 965pt, so i'm not sure how to change the ram multiplier. I'm pretty sure this is my problem, there are some options in DRAM configuration but i don't think any multiplier. Whenever i take the memory clock speed off 'auto' my it doesn't post. Does anyone know how to set the multiplier on a biostar so i can get my FSB up.
 
doh! i used to have a biostar 965pt. i forgot how to change it... 533 or 1:1or 133 or something like that. familiarize yourself better with the bios though. there are settings for it, i kind of forgot. just set your fsb down low, change the setting, and then keep goin to windows to check what divider is being used. takes longer, but it's more of a sure thing. just make sure you back off on the fsb you're runnin though. i've gotten mine up to 499 at 1:1 with my teamgroup ram. wish i could help you out more.
 
Geeze! What ram are you running? That ram is running at 992Mhz! I can barely get mine to post with a 350Mhz FSB. It's 667 ram, so I'm running the FSB at 333 with a 1:1 ratio. With my x10 multiplier I'm getting a good 3.33Ghz.

Not sure how you do yours, but on my desktop (The bottom one in my siggy) you hold CTRL-F1 at the main bios page and it opens a new set of options in the tweaking menu. That's the only way to do a manual ratio on that gigabyte board.
 
I've got OCZ Titanium running at just over 1000mhz 5-5-5-15 :)


OP, gotta change a setting that's currently set at DDR2800 to DDR2533

But for the life of me I've got no idea where it is in your BIOS.

Go hunting.
 
You need to find the settings for VMCH and FSB Voltage.

Those voltages have to be upped a little or almost all the way once you go high on your FSB.
 
I was actually having the same problem but like the poster above me said I have to up the CPU voltage, also I had to change the memory voltage b/c in my BIOS it was setting it incorrectly at 1.9V instead of 2.1V so that could possibly help fix the memory issue as well. After I fixed those things I'm now at 350 FSB and slowly climbing.
