Is this even possible? Quad 8800 SLI?

[carholmes]

I am totally surprised no one saw this, you can see in MuffinFlavored post he only uses two SLI connectors. If anyone saw the "ghetto" version of a tri SLI connector its basically three SLI connectors. In Tri SLI each card has to be connected to the other two cards. This guy would have use 6 connectors so every card would be connected.
So there is absolutely no way this is really quad SLI.
But to me it looks like he has duel SLI or like two SLIed cards for one display and the other two cards for the other display.

[drifter]

like i said in the first post, i tend to believe he is mimmickng the 7950X2 cards and then the SLI connectors are totally in place. in that case data between GPU1 (primary) & 2(secondary) is transfered via pci-e bus, and via sli bridge to GPU3(slave1) and GPU2 (slave2). and the reason he is asking for some knowledge of pc's i believe is that you have to mod the Nvidia quad sli driver with every new release (mod to see 8800 ultra as a dual gpu card).
don't get me wrong, i do not believe this myself yet, so i'm just guessing.
edit: this is what the guy is saying on his e-bay page about the rig:
IF YOU WOULD LIKE A LESSON IN QUAD SLI WE INVITE YOU TO CALL US INSTEAD OF WRITING ABOUT US BEHIND OUR BACKS IN ALL THE FORUMS!!!!

WE ARE FOR REAL AND SO ARE OUR PRODUCTS.

F-ing Stupid IMO

[awdrifter]

If no one can do it here on XS, it's probably fake.

[drifter]

here are the links to the old quad sli and some explanation how it functions:
htthttp://www.mvktech.net/content/view/3198/48/1/2/p://
http://www.bit-tech.net/hardware/200...rce_7900_gx2/4

to summ up, in both generations of the X2 cards an internal PCIe switch via which they are interconnected. and the older generation (7900X2)cards also have an internal SLI bridge. so in theory the gpus could be interconnected via pcie slots (gpu1 to GPU2, GPU3 to GPU4, GPU1 to GPU3) and additionally, as i earlier described, via pcie slots (like the 7900X2 cards).
and since the guy put up a Quad 8800 gt rig, i believe he is using 2 long flexible sli bridges to connect GPU1 to 3 and 2 to 4 (you'd have to twist the sli bridge though), and the rest of the daata is transfered via PCIe bus. (so in this case that would be like mimmicking the behaviour of the newer 7950X2 cards which do not have an internal sli bridge to connect GPU 1 to 2, and 3 to 4)

all this is pure speculation, but so far noone has not proven it wrong a 100%, so so far i'm curious...

I got a C2D Quad SLi board (P6N Diamond)...

[drifter]

hmm, that spacing would even allow to stick 4 ultras with stock coolers. now i wonder if there is something particular to the 680a (because unlike 680i boards it uses 2 570i chips) which made this ebay vendor go for an obsolete piece of hardware? i see the 680a mobo has 4 slots running x16,x8,X16,X8, and the msi mobo u'retalking bout has all 4 at x8 (if 4 gpu's are used).... ideas anyone?
edit: i read on the vendors site that the tech is only available to 680a mobo owners at the moment (and for all 8 series gpus apparently) cause it uses 2 chipsets on 1 mobo(confirms what i said earlier, but i'm still not sure how it all works).

http://www.custombuiltgamingpcs.com the side of the vendor

[Kayin]

Not only 680a, but this 680i as well...

http://www.hardwarezone.com/articles...?cid=6&id=2325

With dual northbridges instead of northbridge/southbridge, it's got the support for 4xSLi. I gave it to the kids though, I hate nVidia pretty much now...

[drifter]

on one other forum i got a forum member to kindly volonteer (cause he has the dual socket amd setup and 2 8800 Gt cards, he'll be getting the other 2 from a friend) and test this. he called the vendor and he agreed to guide him through the whole tweaking process (free of charge btw). so if this works out i'll post a link to the results

[msimax]

any updates?

[happychappy]

any updates?

Come on, we all know what the outcome will be..

[msimax]

and thats..........

[Zytek_Fan]

There is one respectable build this guy did:

Except for him using 7 Thermaltake Thunderblades that's gotta be one loud SOB.

[firas]

so when skulltrail will be released? Is it just a mobo that can do 2 CPU’s & 4 GPU’s?

[Dr.FuzzyBallz]

THAT be sweet.

[johnny m]

Here is somthing interesting. Checked it out with Asus too. Seems for real.



QUAD-SLI EXPLAINED CORRECTLY


You might want to add this to ALL the forums that won’t let us post to it.



1. There are two...two...north bridges on the L1n64-WS motherboard allowing for communication between the two sets of bridged sli controllers. Enabling the sli controller is done in a NON STANDARD method and that I believe is why all the computer forum community people don’t believe it.



OK, HERE YOU GO,

I GUESS THE SECRETE MUST BE LET OUT

...AND BELIEVE ME IT IS A DARN SECRETE.



First you install all four cards to the ASUS L1n-64 motherboard that supports two Northbridge’s



Second you install the drivers for the 2 680a chipsets, that is were the sli controllers are located in case all you computer techs don’t know this.



Third you will see all four cards show up in the device manager



But in Ntunes were you enable the sli controller it does not appear to be there to enable.



Ah... now for the secrete...first i hope you all know once you enable the sli controller it stays enabled until you disable it!



Now simply disable two of the video cards from device manager...not uninstall. Disable.



Reboot



after rebooting when you go to Ntunes to enable the sli controller its there to enable.



Enable Sli



Reboot again



Now the controller for both chipsets has been enabled and you are are in sli with both chipsets



It's the two northbridges working together that allows all four cards to work as one



Go to the device manager and enable the other two cards



reboot again



when the computer boots up you will see all four card with no flags in the device manager,



reboot again and....poof quad sli



This is a non standard method of enabling the sli controller for quad but does give you Quad-Sli ...4 video cards working as one, and not just simply checking a box that says enable sli. this is why all you noobies for a better word don’t believe this.



Of course now with the release of the 169 NVIDIA drivers there is no need to go back into the device manager to enable the second and third card after enabling the sli controller, its all ready done after the reboot. and quad-sli is supported WITH VISTA with these drivers also.



If anyone would like to question us on this feel free to call us toll free

If you question the Whole procedure I suggest you call...



BRIAN AT ASUS 1-812-282-2787 ext 5125.

he is one of the engineers who worked on this project

when the L1n64 board was in its prototype stages.



Now you ask yourself...self, why doesn’t NVIDIA sell Quad sli? Ok the answer...marketing 101...why give the people Quad sli when you can milk them for millions with tri sli first.

[fragmasterMax]

two socket cpu's will never go mainstream (i see bone trail hitting the dust just like amd's 4x4 but maybe not as hard)

[johnny m]

I'm not advertising anything. thats just what i found searching information on quadsli. What do you mean drivers don't support quadsli? If the drivers out now support three cards why would they not support 4 cards?

[Charles Wirth]

Johnny, might I suggest a spelling checker to get a more "professional" look or use firefox, it underlines misspelled words as you type.

Some of us are aware of quad SLI on Nforce boards, some are not. Be happy people are talking about it.

Amuse us with a link the 2K6 score please.

From our test results, you can take the hole AMD project and dump it in the trash. The only good thing we can find that AMD-ATI did was come out with the ATI 3870's, It's the only thing holding them above water

We have our next project set for breaking the 3DMark 06 world record. I believe your intelligent, open minded, have great incite, and a well rounded computer enthusiast. I would love to run our plan by your to see what your opinion is on the way we are going to run our next bench project.

Submersed platform in 3M Dielectric solution HFE-7100 or would you go with HFE-7200.
We would like to go with tri sli for no world record has ever been set with Nvidia video cards

[Charles Wirth]

Taking the world record is not as easy as it sounds.

SkullTrail also has two nv100 bridges for quad sli operation. Once SLI is enabled you get the options for 3 and 4 way rendering.

2K6 score?

[johnny m]

what 2k6 score?

[johnny m]

I know about the SkullTrail platform, but we have reached scores of over 24,587 with the 780i platform with just the processor chilled with phase cooling and regular GTX's. We figure if we can get the hole platform, north, south, voltage regulators, and video gpu's all under -20c this should work. with the video cards well under -20c there should be no limit to how far they will go
