Any room left to overclock a P-III 800 w/133 FSB

[Perryg114]

Well does anybody know if I can get anymore out of my P-III 800 with a 133 Mhz Front side bus. I have heard of some folks going to a 150Mhz bus. Also is the FSB the pipeline between the CPU and the memory or are other components involved. I am using PC133 SDRAM.

I'd say congrats & be thankful that you've got that far!
you'd probably need some exotic active cooling to get to 150fsb, if it is indeed possible!

Well is came as a P-III 800 with a 133 FSB its not overclocked at all at this point.

The FSB involves everything inside the machine, it's the speed, or fraction of speed, which all the hardware comminucates with each other. ISA = 16 MHz, PCI 33 MHz, AGP = 66 MHz, memory is 133 in your case. More times than not, the FSB is limited by either your cpu or memory when overclocking. As for the other components, keeping the PCI bus at a fraction that gives u less than 38 MHz is generally alright, and the same for ISA at 20. Most hardware can do that. Getting 150 FSB isn't impossible, but i wouldn't expect it at all.

Only one way to find out 🙂 Just try it, and watch your temps.

I have overclocked a PIII800/133 on two different occasions for people and it works fine as long as you have good RAM. I used Muskin PC150 in both instances...and ASUS CUSL2 board with an Alpha(w/ delta black label fan) ....both hit 900mhz/150mhz fsb without a problem. I just raised the voltage to 1.80V just to make sure its stable.....other components were of high quality.....sb live ...IBM 75GXP hdds....3COM NICs....
