I bought a controller LSI SAS3081E-R, it seems to be a PCI Express x8
connector. (

I would like to make sure that I won't fry the Card or the motherboard
if I plug this card on a PCI Slots lot which is longer. The white ones
on this picture (

Thank you for your help
Next to the orange slot, you can see four rectangular chips to the right
side of the slot. They're the PCI Express lane steering chips. They're
what is used to reconfigure the PCI Express slots, without using a paddlecard.

The slots are x16 sized mechanically. Even a x1 could be plugged
in there, if you wanted.
The slot configs are (x16, x0) or (x8, x8), and the lane steering
chips are how the slots get rewired. Sensing pins in the slot,
detect what you've plugged in, and that helps set up the
lane steering.
If you have video in the orange slot, and 3081E in the second
slot, the second slot will be receiving x8 wiring. That means
of the total of x16 lanes available on the connector, only
x8 of them are wired up. And the LSI card should be happy
with that.
There is little chance of "frying" the card. It's possible to
"blow out" PCI Express interfaces with static electricity. And
some chipsets are notorious for that. Again, I don't think
you have anything to worry about. As long as you use even a
little bit of antistatic handling practices, you should be
fine. The Intel chipsets aren't the bad ones.
If you were that worried about static electricity, you'd use
one of these. It's a wrist strap. One end goes around your
wrist. The alligator clip, clips onto something shiny and
conductive on the case. (An I/O screw in the I/O plate
area is fine.) The wrist strap should have around a 1 megohm
series resistor, in the path from alligator clip to wrist band.
The purpose of that resistor, is to slowly dissipate static
charge. "Wrapping yourself in a piece of wire" isn't
quite the same thing, as one of these. At work, they used
to insist that I use one of these.

In some cases, the first BIOS that Asus releases for a motherboard,
won't recognize a non-video card, when it is plugged into a
x16 slot. If that happens to you, then you'll need to investigate
whether a BIOS flash update is required, to properly support the
slot. I don't think that is going to happen to you, but I
at least have to warn you that it is possible.
OK, so here's some bad news.

In the "feedback" section, someone tested that LSI card with
an Intel d975xbx2.
"Using a Intel d975bx2 motherboard neither solaris
nor the bios see the card."
That would be the same chipset as is on your motherboard. It
would be the same generation of motherboard.

Your original question mentioned "the white slots".
PCI slots and PCI Express slots are *not* the same thing.
Your LSI card can only fit into one of the two x16 slots.
No PCI slot is suitable for that card. So you can't use
the white slots for it.
HTH,
