All,

I recently purchased 4 EVGA 480 super clocked water cooled cards. When doing my initial

homework I was looking for a board that could do Quad SLI at full 16x my options were the

EVGA X58 Classified 4-Way SLI or the GIGABYTE GA-X58A-UD9 4-Way SLI.

The EVGA SR-2 was not an option do to it not being able to take I7 processors. The main

reason I even looked at gigabyte is because EVGA does not have a formal manual for the EVGA

X58 Classified 4-Way SLI board.

I decided to go with GIGABYTE, when reading there manual I saw the following note.

Note 3) Each PCIEX8 slot shares bandwidth with the corresponding PCIEX16 slot (PCIEX8_1

with PCIEX16_1, PCIEX8_2 with PCIEX 16_2, and PCIEX8_3 with PCIEX16_3). When a PCIEX8 slot

is populated, its corresponding PCIEX 16 slot will operate at up to x8 mode.

I read this and said ok well ill just use the on-board sound and I will be able to have my

video run at 16x inter-slot. Well I got the board and went to do some gaming and guess

what? The on-board sound stinks badly!! I immediately had to buy a new sound card bc my

prior one was a pci slot, I ordered the sb xfi fatality pro pcie. But now one of my slots

runs at 8x bc of note #3 which defeats my whole purpose of the entire build.

My question is does the EVGA X58 Classified 4-Way SLI board have this same chip-set

limitation as the GIGABYTE board?

Also does anyone know how much bandwidth in GB/s that a gtx 480 puts out? not the rate in

which the DDR5 talks to the gpu but the actual data rate that is sent to the pcie bus?

Hopefully me posting this will save someone else the same mistake I made, I need a board

that does not have that chip-set limitation, it may or not even matter, as I have read the

reviews on the differences between 8x and 16x performance, but I like knowing my gear has

the ability to run at full 16x for future growth and also I don't think a sound card or any

card should not down clock the rail to 8x the vendor tells me its a chip-set limitation.

Here are my specs and pics of the build below I will be splitting these up into two loops

shortly they run at 50-60C under load 38-45C idle now. There is a now sound card between

the two slots at the bottom.

Actually, you're GPUs are all running at x8 mode anyway. The x58 chipset only can handle 36 pci data lanes, thus x8x8x8x8 =32 lanes leaving you 4 lanes open. So adding on your sound card won't actually affect your GPU performance at all, nor will purchasing any other motherboard.

BTW your system is sweet, but w/ that price range...

a) your HDD, whatever it is, isn't good enough for the rest of your system.
b) your 1920x1200 monitor is also limiting all that GPU power. Get like 2 more of those!!!

hey thanks for the info, yah I like one monitor don't like my eyes having to cover to much area. 1920x1200 is perfect for me. I have some ssd just didn't bother to put them in the list. My games run of ssd's. Looks like it wont be much of an issue then as all the boards have the same limitations until the new chipset comes out it looks like.

Now just need to know how much in GB/s the gtx 480 puts out onto the bus

No Problem, I'm not sure of the answer to that question. But I seriously doubt that it's saturating the data that your pci lanes can handle if that's what you're worried about.

BTW you know that two 480s is way more than enough for 1920x1200 right? with that kind of graphics muscle you should be using multiple 30"monitors....
