Changing FSB with Asus A8n-Sli Prem in Bios

post #1 of 3
Thread Starter 
Hey,

I can not find how to change the FSB in BIOS, im running "BIOS Version ASUS A8N-SLI Premium ACPI BIOS 1011-005" which seems to be the latest stable release, although this is the BIOS the mobo shipped with.

Also, can anyone just give me a quick explanation on what Hyper Transport Frequency is? Right now it's set to AUTO with options of 1-5x.

Thanks in advance!

The HT is the Memory Bus, it's overall speed defaults @ 5x200=1000MHz.
Most MBs are fine up to 1080 so...
4x up to a CPU bus of 270... any higher drop to 3x
The FSB may or not be used in the BIOS terms, its antiquated and not always refered to anymore even though some BIOS still do, go figure

Cool! Found the controls, also found out that my BIOS has things like AI Overclock and AI NOS, are these things to be trusted? I read up about them in the manual, and they seem to work fine. A lot of things stay on Auto, and what changes is the FSB. Multiplier + CPU Voltage are set to auto. Right now im running a 5% OC, going to use CPU Burn-In to see how it does.


Edit - On OI Overclock 10% with my mobo's AUTO settings my HT went up to 1100MHz, with FSB 220 and HT Multiplier x 5. I changed the HT Multiplier to x4 and HT is at 880MHz, is there a problem with this number being too low? Also, what is the difference between CPU multiplier (options of Auto, x4-20 with half numbers) and Hyper Transport frequency (Auto x1-5)?
