Although, had you clicked on the link to Crucial I provided earlier, they would have shown this to you.
And good call, emax4! I've done these so many times, that it's second nature for me to ground myself without thinking. I often forget to tell others about this step.
Also, for those thinking to add more memory, I'd like to add: After grounding yourself by touching the PSU or case, unplug the computer to make sure the +5Vsb is drained. Some mobos will have an LED somewhere that stays lit when plugged in, and some PSUs will even have one on the back near the plug. Wait until it goes out, typically within ten seconds, and then install the memory. This takes care of a feature called "Suspend-to-RAM" that keeps power to the RAM when the rest of the computer is off (for an instant-on effect). Popping RAM in/out when powered up is a big no-no.
Another consideration is to look closely at the sockets. In Eire's case, they're all white, so she can just shove them in there willy-nilly. If your sockets are paired by color (e.g., two blue and two black sockets), then you need to match exactly
the type, speed and specs (known as "CL-levels") of the RAM, as well as needing to get them in pairs. This is because the mobo is set up to use dual-channel memory, and is why you'll see memory sold in "kits" for a certain size. Although you can use just one stick, the mobo will slow down and resort to single-channel mode until another identical stick is added (and is why I asked Eire so many questions about her specs).
Now, Eire, do you have someone that can download and run Memtest
(or just download the UBCD
, which has it as one of the utilities)? I boot it up, get 'er going, and let it run through at least
two passes before I call the RAM "good".
