AGP Clock Frequency?

[Dizman7]

I've noticed this option in my bios for a long time and I've never seen it mentioned anywhere (not that I've got to great depths to find it anyway). I was wondering what AGP Clock Frequency is? I have an Asus K8N-E Deluxe mobo (socket 754 with AGP 8x) and it has this option to set it from 66Mhz to 75Mhz, and it is default at 66Mhz. Anyone know what it does or if I should raise it or what not?

Just curious, it's been bugging me for a while

the normal is 66mhz and raising the frequency damages the card atleast that is what iv been lead to beleive i killed my old 7500 and probably my sound card doin it but those were pci im sure its the same for all slots.

Uhm, raising the AGP frequency isn't a good idea. I've had mine at 70MHz since I have a sync FSB which means when my FSB is raised the AGP skyrockets as well. It causes instability and most of the time the PC won't boot but I haven't damaged anything yet. Even if you raise the AGP clock it won't give you much added performance so it's not worth the problems...

If you have an async FSB you should always keep the AGP at 66MHz. The clocks for PCI is pretty much half that of the AGP nominal frequency, so the PCI bus then runs at 33MHz. Anything over that and you possibly risk serious instability and permanent damage to your add-on cards. My PCI ran at 40MHz for a while and my sound card started having issues...

Damn! I guess I don't want to do that I just got a X-Fi Fatal1ty FPS soundcard, I would cry if I damaged that thing!

So what is this option on there if causes damage to the hardware almost all of the time if raised?

Now that's a good question... Maybe if you had a really stable motherboard and no add-on cards and a heavy-duty graphics card with increase AGP Voltage it might work? Maybe if you get it to work and not damage anything it gives like a 10point 3DMark difference...

if it's chipset is asyn then do what ever u want ! but u'll not GAIN any more performance by increaseing agp clock ! till u had a amazing card which can CAN CAN utilizeing that badwidth !

2nd there ARE NO NO NO hARD WARE DAMAGE DUE TO raise of agp clock in common (btw if u say it is , then OC can do same but u risk & do such a things )


@solaris i don't think so, raising pci clock , damage card !

i rasied my pcie Frequency and it lead to problems with my on-board marvell pcie mini port
it wouldnt start up or power on

btw if my network port is bulit on to my motherboard why is it called pcie

The integrated network in your mobo uses a PCI-Express link for data transfers. Probably a 1X link. That's why it's called PCI-Express. Or that's what seems logical...
