Do CPU FSB speeds affect MOBO compatability?

My question is about FSB speeds and whether of not they play an issue in selecting an upgrade for my current CPU.

This is my MOBO:


MSI KM266 Chipset Motherboard for AMD Socket A CPU, Model "KM2M Combo-L" -RETAIL


- Specifications -

Supported CPU: Socket A AMD Athlon/Athlon XP/Duron Processors
Chipset: VIA ProSavageDDR KM266 + VT8235
FSB: 200/266MHz
RAM: 2x 184-pin DIMM for DDR266/200; 2x 168-pin DIMM for SDR Max 2GB
IDE: 2x UltraDMA 133 up to 4 Devices
Slots: 1x AGP 2X/4X, 3x PCI
Ports: 2xPS2,1xCOM,1xLPT,1xVGA,1xLAN,6xUSB2.0(Rear 4),Audio Ports
Onboard Audio: Realtek ALC650 5.1 Channel Codec
Onboard Video: ProSavage8 2D/3D Graphic Controller
Onboard LAN: VIA VT8235 integrated MAC + VIA 6103 PHY 10/100Mbps
Form Factor: Micro ATX

I currently have a Athlon XP 1900+ installed which has a 266Mhz FSB. I would like to install a Athlon XP 3200+ which has a 400Mhz FSB. Both are socket A processors so I know it will fit, my question is will it run as intended, or would I be wasting my money?

Thanx in advance -OI

If your motherboard can't handle a 400Mhz FSB, then it ain't gonna run a chip that utilizes a 400Mhz FSB at the right speed.

So what you're saying is that my best bet would be to buy the fastest CPU that has a 266Mhz FSB?

Thanx for replying -OI

personally, if 266Mhz is the fastest FSB your motherboard has, your best bet would be getting a new motherboard and processor :)

You can pickup something like the Asus A7N8X-E Deluxe motherboard for about 100 bucks these days that has a 400Mhz FSB. It's probably the best boards on the market for AMD chips (I've got one, heh)

I hear ya. I wish that $100 would spring up in the garden along with some of his closest friends. Fact is I don't think it's gonna happen that way. I'm considering going 64bit whenever I get the dough saved up. Just looking for a cheap alternative for the time being. Thanx for the added embarresment :oops:

The processor your looking at costs around what $160 - $175 (thats the lowest http://www.pricewatch.com listed) and *should run at 2.2 Gig, 400FSB ?

Pricewatch lists a 2400+ (266FSB) that *should run at 1.93Gig for under $75. Now I'm willing to bet that you can get some primo cooling, and overclock that 2400+ damn close to the 3200+ level for less than the $100 that would be left over from buying the 2400+ processor. :D

Just don't go "Tim Taylor" with it :wink:

Now that's what I'm talking about. Save some bucks and pick up a valuable new skill.

"You have learned--Overclock Lv1"

Sweet! I think that's the route I'm headed. Thanks

You're probably best going with the AthlonXP 2500+ Barton (1.83Ghz, 333Mhz FSB) for overclocking to 3200+ speeds.

Good call Axe, Still under $75 too :D


Hope this person does thier research on overclocking "before" trying it, they seem a little gung-ho :wink:

Don't worry about me. Although I am a little "gung ho" as you say I am aware of the consequences of OC'ing, and I will be sure to do my home work before breaking stuff. :twisted:
