Hi,

Quoted 4 lines

Still can't set multiplier 11. I'm able to run CPU on 10.5x200, but not at 11x200. If I use

Quoted 8 lines

powernow-k7 overwrite_table=1 multiplier=50,60,70,80,90,110
or
powernow-k7 overwrite_table=1 multiplier=50,60,70,80,90,11
maximum frequency becomes 1800MHz (9x200) and it's second to last multiplier...

Strange, works for me:

modprobe powernow-k7 overwrite_table=1 multiplier=50,60,70,80,90,110

dmesg:

Could you please post your dmesg output and the output from 'cat /proc/cpuinfo' after modprobe 'ing the module?

You found a bug! There is an error in the translation table:
(quoted diff) +3 -0
+/* translation table for odd multiplier to fid*/
+static int odd_multiplier[9]={
+    5, 7, 9, 11, 12, 13, 1, 3,        +   
21, +};
should be (13 instead of 12, 15 instead of 13):
(quoted diff) +3 -0
+/* translation table for odd multiplier to fid*/
+static int odd_multiplier[9]={
+    5, 7, 9, 11, 13, 15, 1, 3,       +   
21, +};

That works!
Finaly I have my Barton 2500+ fully modded :D
First, I've set it's FSB from 166MHz to 200MHz (L12 mod) and then it became Mobile (L5 mod)
Now it runs at 1GHz and switchs to 2.1GHz if needed instead of boring 1833MHz :D
Great work!
Thank you all!
