I want some help

[Mictlan]

I want to OC my 550E to a 150MHz FSB, and want your opinion about the following testing.

1.- I going to overclock first to 112 MHz FSB (PCI bus 37.5 MHz) and check if my PCI devices and HD manage the bus.

2.- I switch my PC133 MHz Siemens memory to CAS 3 and switch my FSB to 150.....

But what worries me is that my AGP bus will be at 100 MHz, will my Hercules 3D Prophet GTS Pro work with it? This is because my board only gas 1:1 and 1:2/3 divisor for AGP bus.

Does domeone has any experience with this?

i usually work my way up slowly, like try 110, 120, 125, 130, 133, 1 mhz steps towards the top. then i know exactly where the temps start to go up or it needs more voltage. i don't know about that specific video card but i have had two different nvidea boards up to 112 and 107- just work it up slowly and back down a notch when something gives.

if you get windows errors knock it back down to 100 and run scandisk etc...

sorry, you also might want to knock the pci divider to 1/4 when you start going above 100- what motherboard do you have?

Its best to take smaller steps.
Try around 120-124 then 133 then 140-145 then 150.
The reason for this is you can see how your pc is going to deal with things. If you jump to 150mhz it is possible your cpu could overheat before you realize it.
It your pc thou.
Most gf2 cards are good at high agp bus speeds.
If you get lockups because of it you can set the agp to 1x speed and it should help. If you do not have that option in the bios setting the agp apeture to 4mb will do it for testing then you can get a registry entry that will set it to 1x for windows.

on my MB from 100 to 133 FSB the pci divider is one third and when you get above 133 it is divided to one quarter dont know if that will help but ive thrown it out anyway.

I have an Iwill BD100+ mobo, and checking through the BIOS there's no option no change the PCI divider. I can handle that with the CoolCPU FSB program.

The increments that I have are 100,103,105,110,112,115,120,124,133,140 and 150. I'm currently working with the 105 MHz. I'm burning the PC with SETI all day long and maybe tomorrow I'll try to get to 112.

My main concern was the AGP bus. Seems that Nvidia GeForces II GTS can handle quite some OC in the chip itself but also in the bus. Am I right?

you may be ok, the only problem i forsee is you may have to seriously burn in as you go along. You have a quality card, so your chances are not too bad.

Stable at 105 MHz, burning through it....
