219 OVERCLOCKING
220 Dreambox and other internal readers
221
222 For Dreambox and other internal readers the highest possible clock
223 rate will be auto detected. The mhz parameter lets you override the
224 values chosen by OSCam, if it differs from 357 and 358, but usually
225 you will not set any value for mhz.
226
227 For certain Dreamboxes (especially PPC clones) the default mhz
228 parameter leads to slow ECM times and/or "not found" ECMs. By set
229 ting mhz to values like 200, 300, 400, ... 1600 you can find a value
230 that works for your receiver and your card. The higher the mhz
231 value, the slower the ECM time (strange enough).
232
233 If you choose the value too low, your card is not recognized (no ATR
234 or "card not supported"). If you choose the value too high, you get
235 slow ECM times. Our experience is that either no mhz line, or a line
236 mhz = 1000 works best.

238 Phoenix / Smartmouse reader
239
240 Overclocking does not work with Windows and Mac OS X. Set mhz
241 equivalent to the frequency of the reader. OSCam can not set the
242 frequency of the reader.
243
244 Smargo Smartreader+
245
246 Set the reader frequency with the native Smargo Smartreader+ tool
247 (srp_tools). Do not set mhz and cardmhz.
248
249 OSCam tries to set the baudrate automatically. A standard serial port
250 has limited baudrate settings, so SC overclocking might not work. When
251 using a serial reader the best way for overclocking is connecting it to
252 a FTDI based USB to serial port adapter.
253
254 If overclocking does not work, verify the effective baudrate in the
255 logfile. If it deviates too much from the requested baudrate, the SC
256 will not be recognized (no ATR) and the value for mhz should be
257 adjusted again. The higher the baudrate, the more accurate the effec
258 tive baudrate can be.
