Hmm. My MB (asrock brand) has a pci-e gfx card port, but can only support up
to GF8800gts.
Later cards (by later i mean 8800gtx and such) wont work.
My advice is to look it up at the manufactures webpage and see what counts
for your MB.
Mr.E Solved!
Do you have one of those very unusual dual AGP/PCI DDR/DDR2 Asrock (Via
chipped) boards? There are precious few PCI reasons (as external power
is being supplied to the card and lets assume it physically fits) why a
8800GTX will not work where a 8800GTS will.
ShutEye
I do, yes.
Power supply is not the reason.
My advice stands: Look it up at the manufactures webpage!

Having one of those boards myself, I wonder about the same thing. Asrock say
that the PCI Express slot is 4x, (apparently due to a VIA dispute with
NVIDIA over the licencing of SLI in their chipset, I think) and they have on
their site a very curtailed list of cards which they say they have tested
with the board, one of them being an 8800GTS 320MB model by MSI. An ATI
HD2900XT will also work, we are told. The slot looks exactly like a normal
PCI-E slot, and has the little logo and everything.
So, in your estimation, would an 8800GT function in this 4x PCI-E slot? As
far as we are aware, the slot will supply the required current, it just
doesn't go to 8x or 16x in the bandwidth department. I suppose it's akin to
the old chestnut 'does an AGPx8 card work in an AGPx4 slot. Perhaps. For
such an unusual board (AGP, PCI-E, DDR or DDR2, 2xIDE connectors plus
2xSATA2, Core 2 Duo support, slightly quirky quad core support, some
overclocking potential) it's an amazingly reliable contraption, and it would
be nice to beef up the graphics at some point.

There is a 2.0 version of PCI-Express? Or is this the old PCI-E slot
(enhanced, I believe)?

It really IS a good board for the money.
Paid only 50 euro for it and it's rock solid :)

Since the 8800GTX still is PCIe 1.0 this has absolutely nothing to do
with the compatibility of PCIe 2.0 with PCIe 1.0.
Your problem is very likely a POS mainboard.

My advice is not to buy mainboards with crippled PEG slots.

What do you mean by "old PCI-E slot"?
"PCI Express" = "PCI-E" = "PCIe"

Provided you don't want to put certain GeForce 8's in the slots
provided, from what I'm reading.

8800gts should work:

Can't get everything for 50euro I guess.

Nor the 8800GTS 640M or G92 8800GTS based, at least based on that list
which is slightly stale.
I'm not going to knock that board, you do seemingly get a lot for the
price, including its unique ram support. System board engineering is
critical to long term stability and upgrading, if you don't have a
robust upgrade path you lose one of the selling points.
I just can't help to think there are so few situations where that board
is the best choice for a build, even at that price.

It was the best choice for me, only had the cash for a C2D and MB.
GREAT speed upgrade for almost no money.
Next on the list is a new MB and GFX when I can afford it - 2GB PC5400 has
already gone in.

PCI-e is an enhanced version of the standard PCI slot, not to be
confused with PCI-x which is a 64bit version of PCI. PCI-Express is not
PCI-e.

Yeah, a surprise all round, that board. Having a half decent AGP card, I
wanted more than my old Athlon XP could give. Couldn't justify spending a
lot of money. Got the -SATA2 model and an E2160, overclocked it straight to
2.6 seeing as the FSB hits a brick wall around 290, but the speed increase
nevertheless over an XP2600+ was absolutely astounding, even with single
core apps. So, an £85 layout for the board and CPU made a veritable quantum
leap in every department. It was fine with the old DDR I had but 1gig of
DDR2 pulled out of a dead, flood damaged PC happenned to match the cheapest
stick of DDR2 I could find in the universe, so I went dual channel and
though the difference is not massive, you can feel it.
Stability is so total and exceptional on this board, I can do nothing but
praise it. Another pleasant surprise was the Windows XP OEM install
activating itself without a hitch despite a mobo and cpu change. It turned a
very dated machine into a not half bad dual core thingy with SATA, RAID,
64-bitness and all the rest of it. Of course now I see the incredible
performance of these core 2's it leaves me wanting more, and I can't
remember a time when performance CPU prices were this low. Roll on january.

Yeah! Another happy asrock costumer!
People tend to knock this MB just based on it's price.
But you really CAN get rock-solid performance for low cash :)
And for those that doesn't know it: Asrock is the low-cost Asus (owned by
Asus, mmmk ?)
Their support isn't half bad either - just got a BIOS upgrade dated 20
september 2007, and there's been plenty of those upgrades!
BTW I'm on 290MHz FSB right now with no issues, I'll knock it up a bit if it
stays stable.
300MHz FSB 1:1 with the DDR2 memory and a C2D running 2,7GHz isn't bad no
matter the price tag!
Dr.White
Yeah, running a C2D at over E6700 speeds with that sort of reliability is
not to be sniffed at, at five times the price. The difference in performance
between this particular VIA chipset and the high end Intel or Nvidia
chipsets is very small, too, 5% at worst, and in some cases the VIA wins. I
mean, for what the Asrock costs, can you get anything remotely decent? There
have been 5 bios updates since June, so yeah, they support it and keep
adding VGA compatability in their updates. To me, the fact that it is very
cheap and only has 4x PCI-E does not qualify the board as a piece of shit.
Unexplained lockups or crashes or other reliability problems qualify any
board as a piece of shit, to me. The rock solid operation of this board
alone makes it a fantastic buy especially if you can't afford the thing to
crash on you, ever. That's how confident I am in this board. Still, the
question remains.... has anyone tried an 8800GT on it yet?

Dr.White.

Read my prev link:
http://www.asrock.com/mb/faq.asp?Model=775Dual-VSTA
(not that I've tested it myself)
Still loving this MB though!
Dr.White
read the FAQ, or, more accurately, there was no FAQ for the SATA2 board
until they tested an 8800GT on it. I wonder how easy it would be to obtain
the relevant BIOS for GEN1. But in any case, the board takes an HD2900XT /
old 8800GTS so it's not like we're totally screwed for upgrade options.

No. PCI-X is an enhanced version of PCI 64bit (3.3v only, clock rates of
66MHz, 100MHz, 133MHz and 266MHz). Being a 64bit PCI sot doesn't mean
it's PCI-X.

That's nonsense. "PCI-e" definitely *is* "PCI Express".
