Okay...the 733 is a cinch to put on. Just hook it on the back and use a flat head screwdriver to push the other end down until it locks under the latch. The force is alot, if you try with fingers they will be stressed 🙂 Don't get scared at the force you use to put it on, just be careful you don't slide off the clip and gouge your mainboard or knock off a capisitor. You can use your fingers but it won't be easy. I've [taken off/put on] my 742's so many times and had no problems whatsoever... the 742 uses a different clip (has three notches for the socket latches) but the installation is just the same as the 733 (which I've used as well).
