RAM problem with Asrock H61 M-DGS

Well i can't install a 2gb DIMM in the MoBo because the damn retaining clips won't come up when i push the DIMM in to the slot. Am i doing anything wrong? I am trying to fit a Kingston 2gb DIMM.

it is a ddr3 dimm correct? I can't tell from the pic. Have you tried the stick in both slots?

I have tried both slots and it just doesn't fit, i don't know if it is a DDR3 because usefull information is nowhere to be seen at least in the package.

there are nummbers printed on the ram. Look it up on google
