64bit MB Questions!

[PCTech]

What the world, I must be living in a cave! whats the FSB on the new 64bit chips? I see some of the older 64bit boards have a FSB of 600/800/1000 but the newer ones of the same type (939, 90nm) are 2000mhz observe below

newer:

older:

just curious what the difference is. Also, what about heat from these chips? how hot do they get? Anyother technical aspects of the winchester core 3200 64bit chips I should know about, how much faster than a barton core 2500 are they? noticble faster?

Please help, I must have fallen asleep while these were release!

More Questions:

the first link only has PCI-Express 16x, no AGP8x? that sucks! I guess I one with AGP 8x like the one below will do, whats the difference in PCI-E and AGP8x?

also with 64bit MB's the FSB is 1ghz, would there be a preformance increase by buying DDR500 or higher memory? or would it just be, something to buy and make you think it makes a difference!

nice, very helpful stuff here, just a few questions though... Cool-n-Quiet, is that something that is on all the motherboards? or just the msi neo series (neo4?) Alright, so darn my 5900 wont fit in a pci-e slot, so there is no point in buying a pci-e mb at the moment for me, especially sinse they dont push the textures through 8x agp yet! Thanks again for the info!

So if I buy PC PC3500 per say I could over clock the memory FSB to the normal operating FSB Speed (what 3500 would normally be), it just wouldn't be overclocked really, right? so as long as it stays cool enough inside it will do it?

Please help this confused techie!

edit:
What about Windows XP, does it support 64bit cpu's? Is there a speed increase when switching from a barton 2500 to a 3200 64bit chip?

The Cool-n-Quiet functions should be on all AMD64 boards (notice the itallics). CnQ is a technology that AMD introduced with the 64 bit versions of thier proc. Other MB's should have it although you may have to turn it on in the BIOS and possibly download drivers for XP to enable it.

I'm sorry but you lost me with your overclocking question...

Here's a review of some 939 boards to help you with your research:

sorry for the confusion, if the MB says it supports (example) 233/333/400 mhz ddr memory, thats pc2100/2700/3200 or something like that. and you put in for example pc4000 memory, something thats not listed as supported on the box, will the board detect that memory and run it at the correct speed, or will it slow the memory down? If it slows it down can you overclock the memory fsb to make the memory run at its normal speed? its not really overclocking, it would just be making the pc4000 run at its normal FSB speed, right? I hope i'm not confusing you now! thanks for the links, I will read them right now.

It would step it down... if you put ddr400 in a slot that only supports up to ddr333, the board will just clock the ram down to 333. Whether or not you can overclock is somthing that is dependant upon the board you buy, the quality of ram used and a little bit of luck. And yes, it really is overclocking, at least from the motherboards' standpoint. Your RAM may be able to run faster but that doesn't mean that you won't fry memory controller or burn up your bus by making it run faster/hotter then it's rated for.

I've already lost a motherboard and 2 videocards due to overclocking... they're expensive lessons to learn. Make sure before you embark on any overclocking stint that you have both a good cooling solution for your case and good clean power (that means a UPS not just a $5 power strip).

I stay far away from overclocking memory. I do this because timing is such a bear to deal with when overclocking. Any mis-timing or mis-cue can cause data loss and possibly very severe consequences. Just my $.02

[PCTech]

alright so that sucks!! well thanks for the help! I didn't want to over clock, I just wanted to know if it would be overclocking if I put faster memory in a slower slot and went in bios to set the memory timing to 1:1 or 3:4! thanks for the help everyone!
