A64 3200+ S939 Winchester Overlocking Tips Needed

Just got a new system with these specs:

A64 3200+ s939 Winchester cpu
A8N-SLI motherboard
XFX GeForce 6600 GT graphics card
Audigy 2 sound card
OC Systems 1GB DDR400 memory
120GB Maxtor hard drive

I am wondering what I should set my vCore, mem voltage, graphics card voltage, CPU frequency, and memory timings at? Also what frequency will my FSB run at? I know HyperTransport is different from standard FSB but what is the actual frequency?
 
On the A8N, the manual RAM settings are mislabelled or just confusing. Setting it to "DDR400" really seems to just lock it at a 1:1 ratio. It sounds like they might all actually be ratios to the FSB rather than absolute clock speeds. My settings,

CPU configuration menu:
DDR400
HT Multiplier 4x

JumperFree:
CPU(fsb) 250MHz
CPU Multiplier x10
vcore 1.45v
PCI 33MHz

This gives me a 2.5GHz clock on my 3200+ winchester and 250MHz memory clock (though I'm using DDR500). I haven't tried pushing it much more than that. I don't think that the HT can go above 1Ghz and be stable, so if you go with a higher FSB than 250, drop the HT to 3x. I barely raised my vcore and it seems fine, I idle at 36-40C now and peak around 50-55C (not using my Lian Li case yet, which I hope will drop this more).
 
I wouldn't go 1.6V on the VCore either 😉 Don't even touch the graphics card voltage.

The 3200 is 200x11 at stock. Find the tightest timings you can run at these default speeds (2-2-2-5 is a good place to start). Once you find out how tight of timings you can get, start bumping up the HTT. When you hit a road-block, relax the timings, see if you can go any higher. Once you hit that brick wall, lower the multi and see how much more you can get out of the proc and memory.

It's been hypothesized in benchmarks that async in the A64 does nothing, so don't let one limit the other.

Isn't it 200x10 stock?

If you can, and this sounds ideal, run your FSB at 250 and a 10 multiplier. Leave memory stock and run a 5:4 divider. Should be able to do that without playing with the voltage much. Also, HT should be 4.

I'm new to OC'ing so I just wanna see if I understand some stuff... 🙂

how do you set a divider??? (i never knew what that meant) 😕

haha, don't ask me, I just read the OCing guide thing that's stickied under the Processors and OCing forum section and figured that to be true. The possibility that I'm wrong outways me being right, though 😛

Everyone here is talking about changing the multiplier - I though it was locked on all the A64's.

it is locked but u can lower it.
 
So,

vcore at 1.45
agp stock voltage
ram timings same as now (3-3-3-2T)
and 250x10 cpu/multiplier

any other advise?

oh i almost forgot, should i enable fast writes for my system? i heard that they bring down your g-card oc and give nothing to performance
