How to choose the Crystal and loading capacitor for customized PCB?

Hello guys,

I need your help. I designed my own PCB and use mbed to program. However, it seems that my external crystal won't boot up the STM32F411. A detailed description of the problem can be found at another post of mine: https://developer.mbed.org/questions/61589/Program-hangs-at-SetSysClock-on-a-custom/

The detailed info for crystal and loading capacitor I chose is here:

Crystal: 8MHz ±30ppm Crystal 20pF 80 Ohm -10°C ~ 70°C Through Hole HC49/US http://www.digikey.com/product-search/en/crystals-and-oscillators/crystals/852333?k=X1094-ND

Loading Capacitor: 20pF, ±5%, 50V, http://www.digikey.com/product-search/en?keywords=490-1410-1-ND

Is there anything wrong with my choice? Thank you so much for the help and I really appreciate it.
