My floor is carpet and I haven't had any trouble. Just touch the PSU often and don't scoot around on the carpet itself much.

Most chips are static resistant compared to 30 years ago. It used to be a lot easier to fry a ram chip then it is today...

If you want to play it safe short sleeved shirt or rolled up sleeves and just make sure your arm is touching the case while you put it in.
That or put it in with one hand while you hold the side of the case

These days I don't even bother, except maybe unless I'm building a big server and I don't want the headache of having to report the RAM DOA when it's meant to be installed the next week.

Touching the metal case is more than enough.
Which you have to anyways while opening up your computer case.

I got a free crocodile clip attached to a ribbon....masquerading as a "free anti-static saftety clip worth £5" when I bough some ram 10 years ago!

 Or, even better, run into your yard, catch an animal (that resides underground), and hold it while installing the ram.

nothing ? i dunno i've never had a problem. Sometimes i might touch the radiator but i' dunno if it helps or anything XD
