Short but sweet: ASUS A7V doesn't allow changing the multiplier in the BIOS?

[aa_koch]

I've got an ASUS A7V mainboard (rev. 1.02), and there doesn't appear to be an option to change the multiplier in the BIOS. I've tried upgrading my BIOS (1004C, 1005C, 1007), but this doesn't make any difference. On my friend's board (A7V133), a message appears saying that multiplier changes are only allowed on boards with revision 1.04 or higher. Does this apply also to the A7V line of mainboards, or am I doing something wrong?

You can't change the multiplier in the BIOS, but you can change the multiplier via dipswitches. Read your manual, it is pretty easy to do.

No, you have a rev 1.02, you cannot change the multiplyer. You're stuck w/ using dip-switches. You need to have rev 1.04 or later. I recently upgraded from an A7V to A7V133 to rev 1.05. Check out A7V Troubleshooting and its excellent forum for more help w/ A7V/133 issues...

The A7V never had BIOS multiplier settings. ASUS tried with the original 1005 BIOS but it never worked. But dipswitches aren't THAT bad; after you've overclocked to the max how often do you have to change the multiplier?

Actually Asus never tried with 1005, they where getting the BIOS ready for the A7V133 also which has jumperfree multiplier... The BIOS is basically identical except for RAID so thats why you saw the option in one or 2 BIOSes. They just forgot to hide it for A7V users.

Well, I can change the multiplier via the dispwitches on the mainboard. However, it appears that there is an error in my manual and it doesn't make things easier. I can't really explain because the error is probably in the picture that is displayed next to the instructions, but here's what is said about the dipswitches:

The motherboard's onboard functions are adjusted through the DIP switches. The white block represents the switch's position. The example below shows all the switches in the OFF position.

Now, the problem is that the image they use, shows "white blocks" pointing to the "ON" position. (All white blocks appear closest to the word on as printed on the switch module.) So does this mean that the switches should be set to "ON," to enable JumperFree mode? Or must they all point to the "OFF" position (in the direction of the numbers), to bypass making changes to the settings via these switches and allow for JumperFree mode to be utilised? Furthermore, when they give an overview of the A7V CPU External Frequency Selection, the "ON" position reads: CPU 100MHz, PCI 33.57MHz, whereas setting the jumpers to "OFF" reads: CPU 111MHz, PCI 37MHz. In other words, if I set them to "OFF," the CPU will run at 111MHz, and when I set them to "ON," it will run at 100MHz -- but does this not override the JumperFree mode at the same time?

There's probably a simple solution to this, but the manual's not really helpful on this. And when I set the board to JumperMode, I ran into trouble running an AMD Duron 600 (6 x 100) at 650 (6.5 x 100), even though I managed to run this chip at 900MHz on the A7V133 board.

Anyway... sorry if I sound like an amateur, but this is my first time overclocking a CPU.
