i own an asus A7v with the latest bios ( 1009 ) and an athlon 1.0ghz tb processor
i relize that the highest clock multiplyer on this board is 12.5 and i am at that right now and the highest stable bus speed that i can run this board at is like 105 it won't support 133 fsb cause it has the kt133 chipset
the problem is i know my cpu can handle much higher clock speeds and i heard that some people have gotten it to run at 13 and 14 clock multiplyers but it won't do that unless you own a 1.3 or a 1.4ghz cpu (from what i have found on google.com) and it autodetects the stepping Id or something.
i heard that if you set it to clock mult of 12.5 it would auto go to 13 if you owned a 1.3ghz cpu (which i don't) and if you set it to 5 it would auto goto 14 clock mult (if you owned a 1.4ghz) but i own a 1ghz and want to use these higher clock mults
Can anyone tell me how to achieve a 13 or 14 clock multiplyer out of this dated board ?????

you dont need to own a 1.3ghz cpu to run 1.3ghz

just set the dipswitches at 12.5x and it will run 13x (bios revision 1007 and newer have remapped 12.5 to 13x)

i have an a7v in my server that runs a 1ghz tbird at 1.3ghz by way of 100mhz fsb and 13x multiplier
i cant verify if its the same with 5x and 14x (ive heard conflicting reports, but my cpu wont boot at 1.4ghz so i cant test it)

as a side note i run bios 1008

yeah i already tryed that and it automatically sets the clock mult to 12.5 when i put it at 12.5 it won't point it to 13
i tryed setting it with jumpers and with the bios
i was also considering setting the bridges on the cpu to be a 1.4ghz cpu or something but that isn't possible since it is a TB
Looks like my MB just sucks and is holding me back.
the problem could be overcame with some kind of bios which would just let me set the clock mult the way i want but asus doesn't seem to have that.
If anyone has had any success with getting a TB cpu to run at 13 or 14 clock mult and the cpu is lower by default please tell me how you did it ???????
thanks

I have a 1.0GHz Tbird running at 1.3Ghz on the A7V. I connected the L1 bridges using a mechanical pencil and then set the jumpers to 100 MHz FSB, and set the dipswitches to 12.5X, which it read as 13.0 X. So I am running a 1300MHz, actually 1312 because the signal generator isnt precise. I have 1009 BIOS.

um you said you tried changing it in bios???

are you using and a7v (as you stated) or is it an a7v-e?

also are you sure your using bios 1007 or higher? (when using an older bios the 12.5 is actually 12.5)

Yeah it is an A7v rev 1.03 and i have the 1009 bios version no there is no way to change the clock mult in the bios i have everything set to use jumpers
12.5 just isn't 13
Maybe it is this board's revision that makes it different maybe ?

i only have one a7v right now, but i used to have 2 of them.... the one i have now is board revision 1.02 i dont remember what the other one was... but both worked fine overclocking to 1.3ghz

i dont use bios 1009 (and it didnt exist when i set up the boards) my current a7v that is running at 13x100 is using bios 1008


maybe you should try 1008??? i just dont know :)
