FSB is different every time I start up?!!?!

post #1 of 6
Thread Starter 
I have quiet and cool set to DISABLED.
Right now everything is set to stock

Every time I boot up my computer the FSB is different and therefore the RAM, HT, and CPU clock speed are different as well. In the BIOS it's set to 200MHz but this morning I booted up and got 180. Then I rebooted and got 203. Rebooted again and got 195. Just rebooted and got 205, looked at it again and now it's at 202. What the hell is going on here? Am I going to have to RMA my motherboard?

I had my HT up to 1,200 MHz or so for a couple days. Do you think this screwed it up?

Can you give us some screenies of this?

HTT at 1200 shouldn't mess up your FSB. FSB is controlled by the CPU... and HTT chips are on the CPU (and NB?) which contain multipliers, so the chips (HT chips) shouldn't interfere with the FSB.

CPU could be dodgy, although the motherboard might be setting false values for your CPU. That wouldn't be good.

Try: BIOS update
Different mobo if you've got one.

A known oddity with Asus A8N series MBs ... check the link for more on that.
"BIOS Settings:
As with any MB the BIOS is the key to taking control and ensuring that the MB does what you require. Unfortunately the Asus MB has some idiosyncrasies which will cause you frustration and confusion as you will see later on. "

Will do. Right now things look pretty normal (201.7 MHz) but I'm gonna do several reboots and see what the results are. When it comes to electronics, sometimes problems just kinda vanish...

Ah... I thought it would be something like that.

Ok cool.

A BIOS update would be beneficial, from what the Duke metioned.

Tell me about it. I discovered that the motherboard will not allow you to overclock unless the 1.44" floppy disk drive is enabled. I found this out the hard way after going through the BIOS and disabling everything I didn't need (serial ports, SATA, floppy disk, etc.) All of a sudden I couldn't OC anymore and I had no idea why.
