I'm assuming that you have this problem:
Not much you can do, remove one stick or change the memory to a low profile memory that fits.
i wouldn't remove the memory heatsink, it's certainly possible, but only doable with the memory at low voltages and speeds.
About removing the VRM heatsink, i remember jj saying that if you're not overclocking then you could run the vrm without the heatsink, but it's not recommended and at your own risk
