Hello,
 
I have Asus A7V133, rev.1.05 and Bios 1007 and AMD Athlon 2000+ CPU.
Is it possible to work 1666MHz. (12,5 x 133MHz)?
This works perhaps 2-4 minutes and then stops.
 
Only 1250MHz is possible (12,5 x 100MHz) and so it works.
 
Here I have read this:

No...leave it alone...

Your CPU is designed to run at 12.5*133=1667.
You may have a different problem.
Do you have proper cooling in place?

Please delete. Sorry.

Perhaps it is cooling problem.
When it stops was temperature 50 Celsius. (But it is not much...)
I have 350W power.
(Only one netcard and one harddriver)

1666 mhz core and 133 fsb is the what that cpu was designed for, you may have a motherboard or ram problem.
Which motherboard and what type of ram are you using?

I have Asus A7V133-C, rev 1,05 and 2x512MB PC133 DIMM CL2 (Kingston).
I have too Asus A7V133 and the same problem.

To start, your mobo supports palomino xp chips, so I hope you are not trying to use a t-bred chip.
 The place to start is to make sure you are in jumperfree mode. To do that, check to make sure dipswitches 1 thru 5 are in the off position. Then make sure that the jen jumper is on pins 2 and 3.
If that is how things are now, you may have to go to jumpered mode. To do that, put the jumper on jen at 1 and 2, and switch the dipswitch number three to the on position. Then the DSFID switches need to be 1 and 2 off, 3,4,5 and 6 on.
There are also 4 VID jumpers that you need to check. Without knowing the voltage your chip uses, I would not hazard a guess as to how those should be set. You can get the voltage by looking at the top of your chip, then look on page 24 of your manual.
If you do have the tbred chip you may be able to get it to work using jumper mode, as it uses a lower voltage than the palomino chips
Good luck.
       

Thanks endyen,
 
I use jumpers and I have all just like you say.
CPU is palomino xp.
I try still set more cooling.
 
It works with 1250MHz.

It works with 1250MHz.
(Of course I have set then jumpers for 12,5x100MHz)

Yesterday it was on one hour 1666MHz (12,5x133MHz)
Perhaps cpu is overclockt.
It is used.
