hi,

First what are your computer specs, whar memory is it (ddr, ddr2, ddr3)
What specs, voltage and speed are the the sticks.

put them in the same slot where the 512 mg where.
Your computer might freeze because they are not compatible or might be damage.
You may want to run memtest86

Alright, I've looked over the user manual and it should be compatible.

I would try to boot up with only one stick of ram at the time to see if it boots,

If one of them doesn't boot, the stick must have a problem. If the problem persist, it might be that the samsung ram is not compatible with the motherboard.

You might want to go in BIOS and do a clear cmos.

Is the ram used or new ?
Also check slot for dust.

The problem is with the motherboard you are more limited with memory.

I had the same problem happened and had to change brand of ram to make it work.

The only thing left to do is that
