Will memory run at PC3200 speed on 865P with P4 3.06?

[MobileHulk]

Hi. I have a 845PE motherboard with a P4 3.06. My current fsb is 533Mhz and the memory runs at 333Mhz. I'm running PC3200 dual channel RAM so I was wondering if I upgraded to an 865P motherboard (thely are on the cheap now) can I have a 533Mhz fsb while running the memory at 400Mhz?

I'd like to get the bump from the faster memory speeds, eventually I'd probably upgrade to a Northwood 3.4. I'm cheap and usually stay pretty far behind the curve!

You aren't running dual channel DDR at the moment. The 845 series was a single channel memory controller. The P4 performs best when run synchronously with the memory as I think articles here on AT have proven. The best thing for you to do for more performance would be to overclock both the processor and memory and have them run at a 1:1 ratio.

I don't think a northwood 3.4 would be a large increase over a 3.06B. What can that 3.06 overclock to? You should be able to get that thing up a couple hundred Mhz at least?.

Lastly, if you did buy an 865 mobo just see if it supports a 2:3 memory ratio and that would let you run DDR400 while having a 533Mhz FSB for your cpu but that isn't going to be as good as running 1:1 at the highest FSB your cpu supports unless someone who run it that way tells me I'm wrong.

Actualy I think the P4 doesn't mind Async memory as much as AXP's for example and you do actualy get better performance running a 2:3 memory raito on P4 systems w/ the 865 chipset as long as the PAT like feature is still enabled w/ an Async setting. I think some people did some benchs awhile back proving this, but they did find that CPU clockspeed tending to be the biggest performance factor and that you should not trade memory / FSB speed for clockspeed just push your P4 as high as it will go and then get the memory as high as it will go.
