I speak only english but maybe you can understand me and understand the importance of the question i about to ask. Now in the rated pci-express lanes for the MSI X58 PRO it states 16x/16x/4x. Now this board can run TRI-SLI but my question's are this

1. all x58 chipsets have a total of 32x pci express lanes and they cant max out correct, no matter what other motherboard manfactures do it's a chipset limitation.

2. does maybe this board actually run at 16x/8x/8x with a bios update or something, can somebody verify or find out.

3. What doesnt make sense to me is if the chipset has 32x total bandwidth then and say you ran just SLI with 2 cards at 16x/16x wouldn't the 4x slot suck performance power from the other lanes and how does the motherboard ration the pci-e lane draw.

Apperciate you reading the post, it's pretty important questions. I plan to go TRI-SLI this week and i'm trying to clear up some things. If this board can do 16x/8x/8x via a bios update then problems would be solved.

EDIT: btw the cards are gtx 285's and the new nf200 chipset gives about 1-3 fps difference max in every resoultion low to high in far cry 2, which was compared against 16x/16x/16x vs 16x/8x/8x so clearly the cards are barely pushing or not pushing at all the 8x pci-e 2.0 lane

I have done some research and the MSI Eclipse also has 16x/16x/4x. Now from the information i gathered the 4x pci-e rated slot gets it's lanes drawn from the ich10r controller. So if you we're to run TRI-SLI on the MSI Eclipse it would be 16x/8x/8x and the 4x from the controller doesn't get used. Wheather this is independent from the 4x left over pci lanes on the X58 chipset i don't know but i don't think it is.

That being said then the MSI X58 PRO would follow the same concept correct? being about to run 16x/8x/8x like pretty much all other Tri-Sli motherboards apart from the NF200 based ones.

The X58 Pro SLI board does not have the 'true' 3X16 TRI-SLI nf200 chip like the new Eclipse Plus will. It is SLI X16 in the two dark blue PCI-E slots only. The light blue is only 4X, & doubt it even possible for a new bios to change that. Why would MSI even do that if they could? An entry level board can't be expected to have or provide all the features of the 'Flagship' versions. With the VGA cards you have, the best option is probably to run just two of them in the 16X slots only. Depending on your installed memory & PCI devices, if you 'Enable' Auto Disable DRAM/PCI Freq., it will resolve any empty slot issues.

We don't have your system components listed in your post, so unless your OS & PSU is up to the task, you can't run 3 GTX 285's on this board anyway. If you need the answer to the boards allotment of the PCI-E lane draw assignments, it would be best to contact MSI Tech. Support. http://ocss.msi.com.tw

Do you pay attention to what i wrote? First of all i never said NF200 i said typical x58 boards meaning all boards with out nf200, second of all you can run 3 cards regardless, YES YOU CAN and third the msi eclipse being claimed by other people that if you plug it into the 4x slot the second 16x slot divides into 8/8 so it would be 16/8/8 like all other boards. The reason though is nobody EVER TRIED IT or we don't know about it. So you know what i'm going to find out this weekend and we can put a end to the myth on these boards once and for all. Because Biostar board does the same even the P6T does it. The x4 isn't being used from the 36 pci-e express lanes the 4 lanes are being diverted from the sata onboard making it x40 Lanes.

We will see who is right, you should not talk ahead when you know nothing on the matter.

All forum users here are important. Most of us volunteer our personal time & experience. The forum is not a contest of who is right or wrong. I never said you can't run 3 VGA cards on these boards, however, I do believe, 3 GTX 285's on an X58 Pro will be a bottlenecked, hamstrung endeavor. Just for the record, I've built 3 X58 Pro's to date with '0' issues. Have fun. I'm done here.
