Thx! 
Tuning:
A memóriának próbált már valaki magasabb feszültséget adni? Meddig lehet elmenni?
Ezeket a feszeket lehet elvileg a configban állítani (érdemes a ram feszekkel játszani?):
over_voltage – Sets the voltage for the ARM and GPU processor. The default value is 0. The value range is -16 to 8. For each positive value increment you step the voltage by 0.025V. For each negative value increment you step the voltage by 0.025V. The default voltage is 1.2V, with a range of 0.8V to 1.4V.
over_voltage_sdram - Sets the voltage for over_voltage_sdram_c, over_voltage_sdram_i, over_voltage_sdram_p simultaneously. The default value is 0. The value range is -16 to 8. For each positive value increment you step the voltage by 0.025v. For each negative value increment you step the voltage by 0.025v. The default voltage is 1.2V, with a range of 0.8V to 1.4V.
over_voltage_sdram_c - Sets the voltage for the SDRAM controller. The default value is 0. The value range is -16 to 8. For each positive value increment you step the voltage by 0.025V. For each negative value increment you step the voltage by 0.025V. The default voltage is 1.2V, with a range of 0.8V to 1.4V.
over_voltage_sdram_i - Sets the voltage for SDRAM’s I/O. The default value is 0. The value range is -16 to 8. For each positive value increment you step the voltage by 0.025V. For each negative value increment you step the voltage by 0.025V. The default voltage is 1.2V, with a range of 0.8V to 1.4V.
over_voltage_sdram_p - Sets the phystical voltage for theSDRAM. The default value is 0. The value range is -16 to 8. For each positive value increment you step the voltage by 0.025V. For each negative value increment you step the voltage by 0.025V. The default voltage is 1.2V, with a range of 0.8V to 1.4V.
NOTE: over_voltage_sdram controls three values simultaneously. If you wish to control these values independent of one another, you’ll need to disable over_voltage_sdram and enable the values for over_voltage_sdram_c, over_voltage_sdram_i, and over_voltage_sdram_p.
NOTE: There are two ways to deactivate a volt parameter, you can either completely delete the value from your config.txt or place a “#” in front of the parameter you wish to disable. Placing a “#” indicates that the corresponding line of code is a comment and will not be executed.
