Does INTEL make an SLI-capable MB?

kleox64 said:
There are no INTEL chipsets that support SLI allthough boards that have DUAL x16 slots, that doesnt mean SLI will work unless certified by Nvidia. I doubt people will spend several thousand $'s on a system that MAY work in SLI. Those pci-e slots on those mobo's are really meant for high performance SCSI/SATA/LAN/(and SAS when it arrives) controllers.

The only official SLI chipset is nvidia's intel version, dono about VIA.

your right and your wrong OFFICIALLY there are no intel chipsets that are SLI capable however the Intel® E7525 Chipset (xeon) has been proven time and again of being able to run sli. of course no one can actually afford a xeon so it doesnt really matter but they DO exist

not for any practical porpose they dont, and not everyone is going run out and get an tumwater because it has SLI.

Oh, well, still,its an Intel compatible Mobo, whats the diffrence whether its and intel chip or not?

i wasnt talking about the tumwater board, there are a few e7525 chipset based mobos that are sli "capable" the tumwater thing is 915g based (i dont feel like looking it up again).

*shrug* i thought tumwater was the codename for that 7525 chip, as i have only heard it in refrence to server boards. i915 doesnt support SLI, any way you look at it... gigabyte did some crazy southbridge-link-workaround that wont work as promised like their crappy AGP Express Slots

(NOTE: dont take this out of context, i dunno how well it works, i just dont like gigabyte :p)
 
lol i thought you were talking about a manufacture of that other board that guy showed earlier...my mistake.

EDIT: I have no clue how i got tumwater and gigabyte mixed up :confused:
 
Let me clear up a few things...

1. SLI uses two x16 PCI Express slots, but when SLI is used, each slot is running at x8. Only one slot at a time can run in x16 mode.

2. To answer the original question, Intel does not currently make an SLI motherboard for the home desktop market, but if you read some of the previews on the i955X chipset, you will notice the motherboard that intel sent out to previewers mysteriously had two x16 PCI Express slots on them. Now that Intel and nVIDIA are in bed together, I would assume this very well could materialize (Intel shares with nVIDIA their chipset rights, and nVIDIA shares with Intel their SLI rights).

oh yeah, i forgot about those boards... heres hoping for the best!
 
lithium726 said:

No they are not. Intel doesn't make any motherboards with dual PCI-Express x16 sockets. The only two Xeon boards I know of that support SLi are the IWill DN800-SLi and the SuperMicro X6DAT-G. SuperMicro does have some other boards with dual x16 PCI-Express slots but they do not officially support SLi. There is also no SLi connector included to go between the cards.

Gigabyte has two models of Pentium 4 boards using the i915P chipset that supposedly do SLi.

And of course several NForce 4 boards are comming down the pipe that support it.

One is 16x and the other one is 4x....................

Technically, depending on the specific chipset, it can be one x16 slot and either a x4 slot or an x8 slot. The E7525 for example has enough PCI-Express lanes to do a single x16 slot and an x8 slot. In the case of the i915P and i925X/i925XE you could only have an x4 left over. They simply do not have as many PCI-Express lanes.

But as I stated, testing of video cards with only x4 lanes has proven that that is fast enough for SLi. Barely though.

When you see two x16 slots, the secondary is mechanically an x16 slot. Meaning it will accept x16 cards, but only anywhere between x4 and x8 lanes are actually available.

The 4X slot does not have enough voltage to run a card like a 6800,there are some extra voltage busses in the 16X/8X slot , a 4X slot does not have these busses. The chipset HAS to be SLI or the drivers wont work,Nvidia changed the drivers to eliminate anyone from hacking a non SLI board to run in SLI. It HAS to be a SLI chipset. Some of the future PCI-E cards like sound cards will more than likely need more volts or pathways to work,thats where the 4X slot comes in. In the case of the Intel board we are talking about the second slot is 4X,this is for future use. Do you have a web site with the testing of video card in 4X,i would like to see it,all the PCI-E video cards i am aware of are 8X/16X cards.

first off, the chipset thing only applies to nvidia chipsets, not intel chipsets. if tumwater is working with SLI, then its working with SLI, theres nothing nvidia can do about that.

we arent talking about putting a graphics card in a 4x slot. we are talking about the motherboard giving the second slot the BANDWIDTH of a 4x slot - which in real world performance doesnt matter (remember: we are just today scratcing the limits of the 4x AGP bus)

i dont know of any graphics cards that have an 8x connector, i would like to see that.
 
Might sound like a n00bie sir, but um, I just got my Maximum PC a few days ago and they reviewed a Intel SLI rig w/ 2 6800 ultras. Is it me or is that true SLI? from what that rig did to all their records, I would assume that it was a true SLI.

p4 boards with SLI exist. they are based on the NF4 SLI intel edition chipset, and are not made by intel. this guy wants a board made by intel.
 
Is there any particular reason why Intel has so far not made an SLI board? Do they have future plans in the SLI direction for the consumer?
 
Correct me if I'm wrong here, but arn't all of the SLI boards nForce chipsets? Why would intel make a board and use someone elses chipset?

edit: Sorry, missed several pages in the middle. I'll leave my original comment so we can all have a great laugh at me being redundant. :)
 
i just want to know why you would want an intel mb /chipset when nf4 is clearly better? imagine when asus does something like the p4c800 with the nf4, it will be like 0_0

intel chipsets are the r0xorz

i dunno how well nf4 is going to being accepted in teh intel market - intel's chipsets are rock solid and reliable.
 
Rasha said:
but every benchmark i've seen says the nf4 is faster
Click to expand...
than what? the 925XE?

intel has new chipsets coming out too, do you have any benchies putting the nf4 up against the 955?
 
i dunno honestly i totaly forgot about it already because i actualy use amd stuff but ill try to look it up agian

This is what I've heard too: that Intel stuff is very stable and reliable. This is the reason I'd choose to stick with Intel-branded products.
