166 Bus Speed?

[Shiranai_Baka]

If bus speed IS FSB then how do i change the bus speed? I have the ASUS a7n8x Deluxe 2.0 and i have an AMD 2600 (Max fsb = 333mhz).. Is the memory frequency the option where i change the bus speed because the mem frequency is also set to 166.... anyone who is familiar with this mobo or anyone who has this mobo.. please help! (Ok.. just noticed i posted this in software forums -.- if this isnt the right place please move, TY.)

I'm probably not answering your question, but processors can only run at fsb speeds as high as the bus speed of the mobo.. so it sounds like your amd can only run @166MHZ

Hope that Helps

you can run it at 2.13GHz if you dont have a good cooling on ur cpu (16*133bus=2.13Ghz)


if you got something like Thermalright SLK-800 with an 80mm high speed Delta fan perched on top, you can run the bitch at 2.485Ghz (15*166=2.49Ghz) equavalant to a amd 3100+

if you dont have good cooling it's not best to run it that high... run it at 133

good luck

FSB = Front Side Bus

I think.

there is sometimes a fsb to memory speed multiplier in bios somewhere. or u can set the memory to a specific speed and the bios will work out the ratio

[james_bond_rulez]

fsb is not the bus speed

if you see figures like 200/266/333/400 front side bus speed on the mobo (supported speeds) the bus speed is 100/133/166/200, dont confuse them

also the overall clock is determined to multiplying the multiplyer of the cpu and the bus speed

so amd 2600+ has a multiplyer of 16 times the bus speed of the mobo 133, gives 2.13Ghz system clock

Thanks james bond. (And my mobo can run at 400FSB)

Double that and that gives you your FSB of 333Mhz with the barton.

The manual for your mobo is available HERE.

Page 55 tells you how to set the CPU external frequency which you multiply by 2 to get your FSB setting. For your max FSB of 333MHz, set this to 166MHz.

The memory frequency is discussed on page 56. Using the By SPD setting the speed is automatically detected. If you want to manually set the speed, use one of the percentage settings (multiplied by your FSB) to get the setting as desired in the next field, labelled Resulting Frequency.

Clear as mud

do you know why this is? always wondered....
