Newb - Mini W5100 does this look proper card?

Hi Guys

Just wondering is the true mini WS100 Ethernet? As i want to use the arduino's Ethernet library that works with the normal Ethernet shield.

i got a ENC28j60 but because of the UIPEthernet library i run out of memory on the arduino UNO just updating a I2C LCD Screen, a buzzer and TCP communication to a server to retrieve data.

Thanks for your help.

regards Jeremy.
