Microduino Board and OLED

Using this tutorial

Display is random dots.

In the code this

U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NONE);// definition OLED connection

// nRF24L01(+) radio attached using Getting Started board
RF24 radio(9,10);

The Oled also uses pins 9,10 is this a conflict? or can they share these pins???
