Setting system bus frequency on Asus board?

post #1 of 10
Thread Starter 
I have the Asus A8N-E motherboard and I'm trying to overclock a 3700+ San Diego KACAE. Right now I'm trying to determine what my max FSB is but I have no idea where the setting is in the bios. There are settings for hypertransport multiplier, memory frequency, etc., but nothing about the FSB. Help me!

Should be down the list a bit, "Jumper free config"

I looked in jumper free config but I don't think they include a setting for FSB.

Here's every setting in that menu:
CPU Frequency (200-400) (I think this one might be it but I'm not sure)
PCI Express Clock
DDR Voltage
CPU Multiplier
CPU Voltage

Nothing about system bus or frontside bus. I guess the only thing it could be is CPU frequency. Any settings for chipset voltage on Asus boards?

Thats the one

But make sure your PCI Express clock is at 100Mhz and the PCI bus is at 33.33Mhz

I'm having a hard time getting higher FSB frequencies. I don't really know why this is... I slacked my memory timings and lowered the speed to DDR200, I lowered the CPU multiplier to 5, and I lowered the Hypertransport frequency setting to 3x. Am I doing something wrong or missing something? My PCI is locked to 33.33 and my PCI express is at 100MHz. I don't think theres any way to bump up the chipset voltage on this mobo.

Is it bad to use an 80 conductor IDE cable to hook up a DVD drive? Every time I boot up the computer I get a message that says "IDE channel 1 no 80 conductor cable installed". I assume that IDE channel 1 is the secondary IDE, to which my DVD player is hooked up. Right now I'm using the cable my motherboard came with that says "CD-ROM cable"

I just tried 215MHz x 5 and it wouldn't even let me do that, what's up with this?

EDIT - It won't let me use anything above 200MHz. I think I'm going to live up to my name pretty soon.

I just went through this as well. There is no way that I could find to up the chipset voltage. I was therefore unable to get a stable FSB test any higher than 256MHz. It would boot up to 261, but was unstable. I finally just decided to run at 250MHz with HT multipler = 4 to get a nice round 1000MHz HT frequency.

Another thing about this board: I don't know what speed RAM you are using, but don't even think about setting the RAM speed higher than 400MHz whether it can handle it or not. If you do, your CPU overclock resets to [Auto] and all of your overclock settings are ignored.

HAHA yes I just figured it out! This is the weirdest thing... this motherboard has some glitch where it only lets you OC if you have the 1.44MB floppy enabled. Ain't that some $***?

I turned it on and now it lets me overclock. Very weird stuff. I found the info about this on an ASUS support forum.

HTT to 4x. memory to 2.5cl or 3.

HTT to 4x may be a bad idea because if youre using FSBs of 300MHz+ thats a HTT of over 1200MHz. I don't know how high it's safe to run hypertransport but that sounds pretty high to me.

As I type this I'm running 308 x 10 = 3082MHz. I'm using a hypertransport multiplier of 3.
