Here is a way to make overclock the card using the CCcam.
In your original cccam.cfg will:
# SMARTCARD CLOCK FREQUENCY: / dev/sci0
To overclock is only the frequency meter (mhz) and make the line #
Example:
SMARTCARD CLOCK FREQUENCY: / dev/sci0 5600000

*This means that the card is working to 5.6 mhz, use this setting a conax card, I spent an ECM time of 0.33 to 0.27 s s Do overclock aims to ensure that the response time of the card is faster, we can see in ECM time, the lower the response time better. There are cards to overclock better than others, the NDS and 1rd3t0 are those aguentam more. If when overclock the card fails to appear in Entitlements, then will have to reduce the frequency:

I advise before starting see the ECM time of the card, if it does not overclock to make improvements have no reason to do so and better leave as was, increase the frequency gradually to find that work more quickly and is stable with your card, advise starting with a low frequency, for example 4/5mhz, does not recommend the use of readers phoenix to overclock or that the abuse very often, as in danger of burn the card.
It would be useful to respond to topic with the card they have and the speed of which managed to reach overclock.

Here is some of the best for overcloked cards;

SMARTCARD CLOCK FREQUENCY: /dev/sci0 8200000 (1rd3t0 0.195 to 0.1370)
SMARTCARD CLOCK FREQUENCY: /dev/sci1 5250000 ( nds ECM 0.210 DOWN TO 0.191

SMARTCARD CLOCK FREQUENCY: /dev/sci0 5300000 ( Sky uk 0.191 DOWN TO 0.172
SMARTCARD CLOCK FREQUENCY: /dev/sci1 5600000 (Digialb conax 0.275 down to 0.178

SMARTCARD CLOCK FREQUENCY: /dev/sci1 8300000 ( BULSAT IREDETO 2 PURPLE 0.215 DOWN TO 0.151

SMARTCARD CLOCK FREQUENCY: /dev/sci1 8420000 ( SHOWTIME IREDETO 2 0.225 DOWN TO 0.141

SMARTCARD CLOCK FREQUENCY: /dev/sci1 4800000 ( SECA2 CARD )

SMARTCARD CLOCK FREQUENCY: /dev/sci0 6000000 ( jsc sport 1rd3t0 )

SMARTCARD CLOCK FREQUENCY: /dev/sci0 6400000 ( nds ECM 0.150 DOWN TO 0.110)-Totaltv-old card-

SMARTCARD CLOCK FREQUENCY: /dev/ttyUSB0 3690000 (HRT Viaccess )

SMARTCARD CLOCK FREQUENCY: /dev/ttyUSB0 4000000 ( HRT Viacess )

But this is all by using usb smartreader+

SMARTCARD CLOCK FREQUENCY: /dev/ttyUSB0 7200000 #NL 1rd3t0
SMARTCARD CLOCK FREQUENCY: /dev/ttyUSB1 6200000 #PW betacrypt
SMARTCARD CLOCK FREQUENCY: /dev/ttyUSB2 7200000 #Sexvieuw via
SMARTCARD CLOCK FREQUENCY: /dev/ttyUSB3 7200000 #MCT 1rd3t0
SMARTCARD CLOCK FREQUENCY: /dev/ttyUSB4 7200000 #SRG via2.6


CanalDigitaal SECA smartcard overclocked to 6800000
Digiturk Cryptoworks smartcard overclocked to 12000000

Both with Smargo Smartreader+ running on CCcam 2.0.8

Local avg ECM SECA : 0.310ms
Local avg ECM Cryptoworks : 0.130ms

SKY ITALY if you have it in your dreambox you can put this line in your CCcam.cfg:

SERIAL READER: /dev/sci0 6000000

and when you have server then all nds cards run the best on 8000000 mhz, in smartreader + usb


Over clocking value for Viaccses Card

SMARTCARD CLOCK FREQUENCY: /dev/sci0 5500000

this is for viaccess cards.
and when you overclock then you have to see the card in the Entitlements, when it's not showing then you have to put les then 5500000 = 5.5mhz.
this is for a dreambox internal reader !!
