Mac Pro 3.2GHz Ram Installation Video - Where?

Not long ago I ran across an online video explaining the steps for
installing 8G of additional RAM in the new 3.2GHz Mac Pros. I ordered
the 3.2GHz (below) and will beef it up to 8Gigs. The video guide at
the OWC site is for last year's Mac Pro (3.0 GHz). I was sure the
newer video said the upper RAM Riser card was reversed resulting in
the cards facing each other. The current video shows the cards as
sliding in, one above the other.

I can't remember where I saw that first video. Does anyone know its
url location? I've searched DIGG and OWC without success. It is
always much easier to see how it is done rather then try and have
someone explain it to you. I know it isn't hard to do but doing it
right the first time is always nice.

While I'm here - the new machine comes with 2Gig of RAM in 1Gig
modules while the 8Gig I ordered from OWC comes in 2Gig per module - 4
modules in all. I know they have to be inserted in pairs or sets but
exactly where they should be placed has me searching for that
installation of RAM video. And I'm not sure if I can keep the
original 2Gig of RAM in the machine to equal a full 10Gig or not.
Does anyone know? I'm currently running the dual core 3.0GHz Mac Pro
with 4 internal TB of HD and and an external 2TB LaCie HD. I'll be
moving the HDs out of the old Mac Pro and into the new Mac Pro. What
I can't do is transfer the old RAM to the new Mac Pro and once I have
the new machine configured and my data migrated over I'll put the
3.0GHz w/8Gig up for sale on eBay. I have two 30" Apple Cinema HD
displays and a third external LaCie optical drive. I'll also transfer
over a wireless Mighty Mouse and the new aluminum keyboard. The
tethered mouse/keyboard arriving with the new Mac Pro will go with the
old Mac Pro at sale. Here's my new order:

AirPort Extreme card (Wi-Fi)
Two 16x SuperDrives
Two 3.2GHz Quad-Core Intel Xeon (8-core)
Apple Mighty Mouse
Apple Keyboard (English) + Mac OS X
2GB (2 x 1GB)
1TB 7200-rpm Serial ATA 3Gb/s
Accessory kit
NVIDIA GeForce 8800 GT 512MB (Two dual-link DVI)

The machine should be delivered by March 1 and I suspect OWC will send
the RAM before then so I'd like to get a running start on how to
install the RAM and find out if I can keep the original 2G of RAM in
the machine along with the additional 8G.

Thanks for any help and advice. It is always appreciated.
