OC questions

[jema]

I'm thinking about putting a retail P3-800E/850E in my ASUS P3B-F and bumbing the FSB up to 133. What I can tell from the BIOS settings I should be able to keep the PCI slots at 33.

Questions.

Is there any way of telling how fast the AGP bus is running? Would like to keep it at 66.

Are these Intel parts, with appropriate cooling, usually up to this level of OCing or am I really pushing it?

The P3B-F automatically defaults to 1:1 between 66MHz and 83MHz FSB, and then 2:3 from 100MHz up. There is no 1:2 setting available on BX chipset based motherboards, so at 133MHz FSB, your AGP will be running at 89MHz.

I just installed a retail P3 850 cB0 in a good BX board with good RAM - it would do 1000/118, but could not make the next jump to 1050/124. I think this is typical for chips at 800-850. Better results may be achieved with a 700-750 cC0, if I'm not mistaken. I just wanted a stable 1000, and went with the 850 sort of as a safety net (rather than risk getting a 700 or 750 that was a dud).

I would NOT jump right to 133MHz FSB. If you are set on 133MHz you should get the 800MHz version and a SWEET heatsink/fan combo.

Any PC133 should do.

Good luck.

You cant keep the agp bus at 66mhz with a bx chipset at 133MHz fasb. The chipset does not have the proper divider.

Thanx folks.

I think I'll go easy on the poor thing, maybe 110 will be enough to calm my need for speed
