View Full Version : AGP and PCI Bus Speeds. What is safe?

So, I've been playing with this 1 gig 266 chip.

My question is: How fast can the Agp and pci bus run without causing problems to the cards/harddrive.

AGP normally runs at 66 and pci at 33.

I've tried a lot of different multipliers even getting the chip up to 1400 at 8.5 X 165. but at that speed the pci bus is at 41 and the agp is 83. I'm feeling these speeds are too high and don't want to risk blowing up my cards.

Any feeling regarding apg and pci bus speeds?


cheers :)

as long as you have high quality components in your pci slots and a good video card, you should be able to go to at least 150Mhz FSB without a problem... above that I don't know though, I've never dared to go beyond the 150 point...

is say to be safe to keep PCi under 38, and agp under 84, but that is me and i dont got them money to replace many burned up parts- but also it depends on what divided the mobo has if its hot a 1/5 divider than your in great shape but like the Epox 8k7a+ its got a 1/6 divider which memory alloowing you cna get over 190FSB and still be in spec with PCI and the AGP slot-just ask winld andy c

33 Mhz pci-bus is really safe :D

No, serious I think it depends too much on the commponents your talking about... I'd say trial and error (but be carefull: I once had all my mp3's broken cause my harddrive didn't like 42 Mhz...

Everything is "safe" you know. I run my FSB at 150Mhz, and the PCI runs at 37Mhz, and AGP would be 74Mhz. I have an Abit KT7A-RAID, and windows 2000 will boot with the bus speed set to 183!!!! Yes, that is right, 183Mhz!!! But my RAM can't handle it so the system crashes when I try to play a game or whatever.

YOU CAN NOT FRY ANYTHING if you set your FSB too high. Your system just won't post, so you reset the BIOS, no big deal. EVERY FSB, PCI and AGP speed is safe as long as you are not overheating anything.

it doesnt fry the components.........it only puts them under stress
