Where's my bottleneck?

Ok, i'm using:

-Athlon 64 3200 (2 ghz, 1mb cache)
-2x 512 Corsair XMS Twinx pc3200
-MSI K8T NEO
-a pretty lightweight Award 300w power supply.

So far I can't seem to get my fsb above 210 with tight timings (2-3-3-6) or about 220 with pretty loose timings 3-4-4-8. It seems like the ram, while not being capable of getting into that 300 range that i've been reading about, still should be able to go higher than this.

1) What's most likely holding me back? Is it the motherboard or is it actually likely to be my RAM's cap? What should that RAM be getting up to?

2) How much of a factor is my crappy power supply in achieving higher speeds, not the safety of my components.

3) Also, if i did want to get up into that 300 range, what would i need? Some ocz pc 3700 and a better motherboard like that DFI lanparty one?

    These guys have been running a lot of memory at 270-300 on your mobo.
    What would I do? Get a better PSU. And get a stick of new memory.

    I looked through the link but i didn't see them talking about my motherboard anywhere. I've actually heard some people say that the k8t neo can't go above about 220 because there's no pci/agp lock.

    Caxus, is the agp speed set to 67 in the bios? Note 67.

    Corsair XMS Twinx pc3200 modules probably aren't based on Samsung's new TCCD, nor are they likely to be based on the old Winbond BH5 modules. Unfortunately, almost any chip that came in between these chips from Winbond and Samsung don't perform well above about 15MHz beyond stock speeds.

    That's why Corsair offered 2/2/2 PC3200 in late 2002/early 2003, but promptly went to 2/3/2 or 2/3/3 when the stock of BH5 dried up. It wasn't until Samsung's TCCD was released that 2/2/2 3200 came back with the XL series of DIMMs.

    You could pump stellar voltages through the chips to get up to 230/240MHz, but from my perspective, it seems your RAM is hitting its cap -- there's a high chance your chips just aren't destined to be more than pc3200.

    try this.... go into your bios. then find the htt transport multi it should be sitting at 4 or something turn it down to 3 and you shoudl be able to hit 266 at least and change your ram divider if you dont have one... you should have a thing in ram timings that says 1t put it to 2t or auto that should allow your ram to hit 250 im using ocz pc 3200 ram and i have it at 258 with timings as such(2.5-3-3-7) with a vdimm of only 2.7.
