PCI bus speed @ 38MHz

post #1 of 9
Thread Starter 
My PCI bus speed is locked with my FSB, and I can't unlink it.
Is a bus speed of 38 MHz dangerous, like for losing files?

I'm overclocking a P3 Coppermine 667: 133MHzx5

And I'm only able to overclock it trough jumpers, wich set the FSB.
The motherboard only gives me 2 options to overclock higher then stock:
142 FSB, 35 PCI bus
152 FSB, 38 PCI bus

I think the 142 isn't much of an improvement over 133 because it is only 6%, the 152 is around 14% wich might be noticable.

I think 38 is the maximum you will want to push the PCI bus. So I'd say you are fine at 152.

Just try bumping the FSB and testing stability then if needed increase vcore.

The 142MHz FSB didn't work, not even at 1.85 vcore...
I don't now what's wrong, it gave me blue screens when loading windows...

Could the blue screens come from my memory? Should losening the timings help?

I losend the timings to 142MHz: 3-3-3-6, now I can boot, and run Orthos for 1 hour, haven't tested more.
Then I tried setting the jumpers to 152MHz, with the 3-3-3-6 timings, still no luck. Altough I don't get a blue screen, before the welcome screen, I only see my mouse with a black background.

So at 152MHz I tried highering the voltages again, also no luck. I highered them to 1.75v with a stock of 1.6.

I have no idea what is limiting me for the 152MHz FSB.
And I can't find any memory voltage settings/jumpers.

Please help me get 152MHz FSB..

I finally got the 152 FSB, I found a way to put a divider on my memory.
Current settings are:
152MHz FSB
5x Multi
760MHz CPU speed
114MHz memory
2-2-2-5 Timings
1.7v vcore
100/133 Divider
