CPU and Motherboard FSB

[sammclean23]

Hi All,

Just a little confused...

As part of a project iv been required to upgrade a system using this board:
Asus P5QL-VM DO

The processor iv chosen is an Intel Q8400.

Would I be right in saying that, because they both have the same FSB Speed (1333mhz) that they can both run at full speed due to neither having to slow for other, so to speak.

Iv trolled around trying to find the answer to this but just a bit confusing..iv built gaming machines all my life but never really been asked "so why did you pick that processor"

If anybody can shed some light as to whether the CPU and Motherboard should have the same FSB, I would be extremely grateful as this is quite frustrating.

Thank you in advance, I appreciate any replies.

Sam

Wtih 20 views, is there anybody that can explain the confiugration/significance of the CPU FSB and Motherboard FSB?

The best way to find if a processor will work with a motherboard is to go to Google. Type in the motherboard model on the search and find the manufacturer website.

I found the Asus manufacturer website and the Asus P5QL-VM DO motherboard processor support list. Here it is:
http://usa.asus.com/product.aspx?P_ID=mF3Leph339ZGlwdz&templete=2

The Core 2 Quad Q8400 is on the list so it will work with this model of motherboard.

Its the explanation part....

I know it supports it (the manual says so) but what is it about the Front-sde bus speeds that makes the two compatible (i.e. without causing bottlenecks)

Apologies I know what im asking is vague, if anybody does know what Im getting at though speak up

For example, the motherboard has a fsb of 1333mhz, what if I purchased a processor that had a slower FSb? would there be speed differences? Will the faster bus slow down?

Honestly, I wish I could answer that question for you. But now that you've asked it, I'd like to know the answer, too.

Anybody?

Front Side Bus (or external data bus) connects the processor to the motherboard. All data entering or leaving the processor comes through the front side bus on this motherboard. Other motherboards use Hyper Transport Technology or Quick Path Interconnect (but that is another discussion).

If the frequency of the front side bus was lower the computer would run at a slower speed. The processor determines what frequency the front side bus runs at. The processing power of a system would be less using a processor that had an 800 megahertz front side bus over a processor using a 1333 megahertz front side bus.

Excellent! Thanks a lot...
