It should be ok to just bump it up to 400, if your looking for maximum performance tho, i would go about it as i explained, loosen all your timings / lower the multi to x6 and bump the FSB up in stages of 5MHz untill it doesnt post, when you get to this point, up your voltage to the CPU to the next setting, if it doesnt post again lower your ram divider.. if it still doesnt boot, you've found your boards max HT(FSB), the put divider back and voltage back ( You should be able to get it higher with more volts/lower divider tho, and by lowering the divider you can still get a good overclock on your ram.. dont worry about that), next put lower the fsb to a fair setting you dont want to be running max FSB on your board 24/7 ( Mine goes 350 but i wouldnt run more than 300 on a daily basis + my ram holds me back from getting any higher on my current settings). Now from there you bring your multi back up to x8.5 and see if it still posts you should then have a nice speed on your CPU and your ram should have a nice speed on it aswell(Dont forget to stress test for stability tho), If your happy with the speeds, then its down to getting your tight timings...
(Forgot to add in there, your Rated FSB.. i take it thats equivilent to my HTLink, you can lower that to get stability as it never really fully saturated and never really needs anything more than 1000MHz.)
Basically start from the top, lower it 1 setting at a time and post.. test it for like 15 mins on Prime95 torture to make sure its stable, when it becomes upstable.. put up 1 again and then move onto the setting below.. repeat this till you have all your timings sorted. This is the part that takes the most time to do, it may take you a day or 2 of going at this for some time to get it all done.. the end result will pay off big time tho. Use Everest ram tests before you start.. check your scores in ram bench's.. run everytime you change a setting, you will start to see the perfomance boost you are getting. I would also run a 3DMark05/3DMark06/PCMark bench before you start so you have a reference for the performance gain you are getting.(I personally get an extra 3k on 3DMark05 from my overclock, my ram latency has gone from 65ms to 48ms and my Read/Write/Copy scores have near doubled from when i started).
This is my current settings, ive tryed every way of getting better results but my ram holds me back big time, and i didnt see the point in buying new ram when i decided to overclock this(As i had the system nearly 2years when i done it) + DDR400 is way old news lol. So im just happy with what i got out it. ( Take no notice of the 1 Thread 1 Core, ACPI Tweak
)
These are my everest results also.
Your sitting with a nice overclock there, but it would benefit you more if you did overclock your ram, what sticks do you have?
Also could you post a Everest benchmark like mine.

(I was install when i done this, its just an example on how my ram performs compared to newer ram/systems due to overclock)
But good luck man, if your ram can handle a nice overclock you onto something really good there, 3.4GHz out of that CPU is a nice overclock, just gotta work on an all round stable overclock now
, If your motherboard can handle it.. you should get around 3.6GHz with these setting and stable
450x8.0 = 3.6GHz / DDR 900, but thats a pretty basic overclock.. you could do better.
