Formula for AGP/PCI Divider?

RWB · April 2004

I have my Athlon running at 2.2GHz, that is 220MHzx10... I am recieving faulty work units in F@H though... but everything else seems to run fine.

But I want to know how fast my AGP and PCI bus is at this speed since I have no dividers appearently or information anywhere in my BIOS on it. How do I figure it out?

depends on the mobo, nforce 2 boards are pci/agp locked at 33/66...

This is a K8T Neo, I wouldn't be asking if I knew my AGP/PCI bus were locked

erg, I forgot to add the 64 bit to Athlon64, I thought I had included my MB and CPU at the beginning of the post, tonight is wearing me down already :P

Also, how can I BE SURE my memory is running a certain speed? In the bIOS it is set to stay at 400, or at least I think so(it never really says for sure on anything). Yet in Sandra it says "220MHzx2".

But I have to bump it down a bit, just had a BSOD while typing a different message, and now I can no longer remember what it was about too.

use cpuid's cpu-z or something similar to get a reading. i'm not sure i'd trust sandra, i thought that was based on performance

Thanks, I never used CPUID before, it's nice to have. My memory is actually running 215MHz x 2 = 430MHz at CAS 2-3-3-6... never been that high on this stuff before.

Although I still wander what my AGP/PCI speeds are, and if the crashing I was having was becuase of that or my memory. It's only PC3200, I guess it's time for some Voltage adjustment tests, it all seems stable at 215MHz

hehe 14,300 3D Mark 2001 points.

My system is a mess too, I am surprised. I haven't OC the Card, all the software settings are Default, in fact I am using the StarStorm drivers which are set to "Quality" it's highest setting... and still I get that high of points. I used to have to OC the HELL outta the card to get that high, and the system. If i remember correctly, I had to get my P4 2.4B to 2.9GHz and my Ti4600 to 320/700(default is 300/650) to even TOUCH 14K. Yet this Athlon64 runs less than 2.2GHz and beats the crap outta the Pee4.

I wish I had a 64bit OS to play with, one that worked well at least.

Ohh yeah and 3.33GBps with the Sandra Memory Test. Gonna have to post some pics.
