hi!
I have problem with CPU frequency on my RB532a.
Since ever i’ve got cpu freq set to 399Mhz and routerboard was working just fine (and still it does) but i noticed that cpu is downclocked to 199MHz
After quick lookout over board i’ve found some curved capacitors so i have replaced them all (slighty bigger than oryginal) but after this cpu is still clocled at 199Mhz and i cant change it…
