Quickie: PCI/AGP frequency

[WyWyWyWy]

Hi all, just a quickie...

Is there anyway I can check my PCI/AGP frequency or divider?
I would like to know how does it related to memory divider on my board...

Many thanks.

Umm...

Sandra can probably tell you.

But if your PCI frequency is something other than 33mhz, your boards won't run.

Nah, all of my PCI cards have been able to run up to 38MHz, and some could do 42MHz. When you overclock the memory bus, the pci bus goes up also.

Of course this all depends on what your memory, motherboard and PCI cards can take.

Screw the PCI cards. Usually, it's the HD that can't take it, then it's Data-Loss City.

No prob upto 45mhz PCI with my Seagates (haven't gone any higher yet)....

[WyWyWyWy]

Thanks but no Sandra won't, or at least I can't find it.

Anything else?

P.S. Just to say that of course my Bios won't let me lock it at 33 thats why I'm asking.

When I did overclock I never ever found a hdd that took more than 38

It's either the hdd or some PCI card on my rig, but it just won't go over 38, right now I'm at 35.

I'm also having issues when it's "underclocked" at 30

Have you tried the latest version of WCPUID? Not sure if it will, but it might...

[WyWyWyWy]

No it doesn't...

Desn't it show the frequency of PCI/AGP in the BIOS settings menu? (My EPoX does).+
Otherwise you have to check the mobo manufacturers homepage about the dividers and at which FSB frequencies they are changing. Newer boards often have a 1/5 divider, making the PCI/AGP oc'ing less troublesome (I can run a FSB of 190 here, resulting in a PCI clock of 38MHz).

Best behaviour in this field is shown by NForce boards, they allow a fixed setting of PCI-/AGP clocks independent of FSB.

Some even have a 1/6

Just got some information saying that divider is hardlocked to the chipset, in my case SiS645.

Anyone know whether it automatically sets divider to 1/4 with this chipset?

Many thanks.

EDIT:
Or how exactly do I check this
It is not in BIOS, it is not on MSI's site, it is not on SiS's site...

I am guessing a bit here, but from what have seen.
It automaticaly sets it.

124 and above 1/4 divider

150 and above 1/5 divider

I don't know when the 1/6 divider cuts in tho.
