AMD Athlon XP 1500+/266 FSB PROCESSOR CPU

[Garfield]

What exactly is meant by "266 FSB"? Is this the highest bus speed that the processor handles? Thanks...

OOPS! THis should go in the AMD section. Anyways, it means the bus speed between the CPU and memory is faster.

[Garfield]

Faster than what?

[Morbid]

Faster than 100 FSB. See, think of the 133 FSB(DDR) as an 8 lane wide road... data moves with ease down this road. If you had 100 FSB(DDR) the lane is narrowed to 4 lanes, making more traffic. If you have just a plane ol 100 FSB the it narrows even more to 2 lanes, making traffic back-up more. Thats the best way I can describe it. Thats what it means to my knowledge, perhaps i'm wrong and someone can correct me?

well i know i couldent have discirbed it better;)

So, when it has "266 FSB", the processor can handle anything up to 266? Or, does this just allow it to receive more data at once?

Also, what is meant by 1500+ in "AMD Athlon XP 1500+/266 FSB PROCESSOR CPU"? Is this the processor speed in mhz?

[bobt17]

the cpu runs a DDR(Double Data Rate) fsb so 100fsb=200fsb DDR
and 133fsb=266fsb DDR. the cpu accualy runs on a 133fsb but it transfers data as fast as if it were on a 266mhz fsb

[Garfield]

So, is 266 FSB a limiting number? Or just a "for your information"?

a "for your information" just whatever fsb u set it to would be automaticaly doubled basicaly

100=200

133=266

[Garfield]

So are you telling me that I can't OC the FSB over 133 because the CPU can only handle 266?

[bobt17]

no thats not what i am saying
what i am saying is whatever fsb u do set is doubled and 133/266DDR is the default for athlons and 100/200DDR is default for durons

[Morbid]

my FSB is at 150 (300MHz DDR) and doing just fine :)

[Garfield]

Is you processor 266 FSB? And it's still holding up?

But what significance is the 266? Is this number simply telling you how much data can be read in? Or is it deeper than that?

[Morbid]

Yes, my processor is 266. 266 means that your FSB is running at 133MHz.. and since it's DDR (double data rate) it's running at 266. The faster the FSB, the better performance you get (also refer to my reply where I talked about the FSB as a 8 lane road). Hope this helps! :)

[Garfield]

So, the higher you OC the FSB, the higher that "266" goes?

yes

[Garfield]

Okay, I understand now! Thanks!!! :D

[Morbid]

No problem :)

>> AMD Athlon XP 1500+/266 FSB PROCESSOR CPU <<

What does "1500+" refer to?

[bobt17]

it would outperforme a tbird or pentium4 with 1500mhz even tho its only a 1333mhz cpu

Oh :D
