Nvidia Chipset query
Discussion
Further to my other thread about pc problems...
I had a faulty mobo which is in the process of being refunded.
I ordered another last night and just had a quick question about the chipset (I can't seem to find rock-solid info on my question)
Basically, it's an nvidia 570SLi chipset on a mid-range gigabyte board (this one - http://www.scan.co.uk/products/productinfo.asp?Web... ) I just wondered whether that chipset is capable of running 2 8800GTX's in SLi?
With the release of the G92 GTS prices are dropping and I as the GTX is new to me I thought about just dropping another in at not an enormous amount mroe £.
Obviously the board has 2 PCI-E x16 slot's but I've read conflicting info as to whether the chipset can run SLi x16 slots or whether it restricts SLi to x8. If so, do you think I'd be bottlenecking the GTX's? And if it would restrict them, would it really be worth another?
Thanks

Here should have all the info you need : http://www.giga-byte.co.uk/Products/Motherboard/Pr...
1. 2 PCI Express x 16 slot
2. 3 PCI Express x 1 slot
3. 2 PCI slots
1. 2 PCI Express x 16 slot
2. 3 PCI Express x 1 slot
3. 2 PCI slots
Thanks very much
I can't really seem to find an answer there either.
I know it says it has 2 SLi capable PCI-E x16 slots, but the bit I can't find, is whether the chipset will limit the cards (8800GTX's in this case) to the x8 bus...
I don't know if in that case, the x8 would bottleneck the cards.
As per-
As you can see on 570SLi it says (SLi x8) and I'm a little unsure what the impact of that will be

I'd check and ask Gigabyte..
From the manual, for that mobo..
To enable the SLI function, install two SLI-ready graphics cards into the PCIE_16_1 and PCIE_16_2
slots. (It is recommended to use graphics cards of identical brand and chips. For example: GIGABYTE
GV-NX76T256D-RH.)
It starts to look like they might both be x16.. but you never know, it depends on how sneaky they are!!

hmmm... from here : http://www.ocworkbench.com/2006/gigabyte/GA-M57SLI...
"It also supports 2 x 8 PCIe lanes sfor SLI operation."
although there are 3 revisions of that mobo..

Thanks very much for that. "It also supports 2 x 8 PCIe lanes sfor SLI operation."

Haven't seen that site before!
I guess that means it doesn't support x16 SLi lanes! Bugger!
It looks like if you want full x16 lanes you need the 590 SLi chipset. I didn't really want to spend the extra (that board was £48) and a 590 SLi was approx. £95, for something I might not even use... I guess the next thing to find out is, if the x8 SLi lanes will bottle a GTX...
Bloody chipsets, why are there so many!!
Out of interest, I posted the same question on the toms hardware forums and received a response with this link -
http://www.techspot.com/review/45-nvidia-nforce-65...
It's a comparison between the 650i & 680i chipsets and shows that the 680i with it's x16 SLi support benefit no more than 2 FPS, so it looks like GTX's wouldn't be bottlenecked.
Which is nice
