hey ronaldo, nice bro, try to reach 4ghz, you will be very happy with 4ghz on air......go for 400x10 with 1.5v on the NB

This isnt an eVGA board, this is a reference board designed by nVidia and made by Foxconn......eVGA is just the distributor, think of nvidia as the production studio and evga as the publisher.

I am aware of that but Foxconn makes the board to EVGA's specifications.

[Leeghoofd]

Well if it's a reference board of Nvidia I really doubt EVGA has a say into it as prolly XFX and co models will look very very alike. EVGA and XFX just put info via users to adapt the bios and co , PCB related it's all the design of the Green team...

[Gl@re]

if anyone finds this board in stock somewhere in the US could you please post it. so far i have found this place which says they will have it tomorrow. http://www.keenzo.com/showproduct.as...1179060&ref=GB

MotherboardPro is going to start shipping some out when they get resupplied. If you really want one, it would be good to secure a pre-order.

Nope, all eVGA does is place their sticker on it and sell the board....there is no physical difference from the xfx and evga boards.....exact same boards.

just opened the board and the spring for one of the vreg heatsink screws is unraveled, it seems to run ok with that screw out but its annoying that something would ship from the factory like that. Also once I install the board in my case and set up the watercooling I am not really going to want to take it out to deal with that screw (assuming I have them ship me just a screw and not a whole new board).

[Robilar]

The screw is supposed to be there. Apparently it is connected to one of the sensors. All of the boards have it

[joe.denice]

well i just slapped in a 3rd video card for tri-sli.. I will do some benching and testing later this week. I have to get a new ups as my current one will overload once in 3d mode.

[jkresh]

Robilar, I know the screw is supposed to be there but with all the others the spring is between teh screw and the board and with that screw the spring is half way off the screw and would touch the motherboard tray

Bad experience with TRI-SLI I was getting artifacting at about the 2 minute mark with atitool. Still with all three cards I could boot into windows at 812mhz on core.

I've started mounting wb's so I shouldn't have that problem anymore.

yeah I have notice the spike in heat with 2 of the video cards, I am going to play around with my setup tonight to see if I want to keep the 3rd video card or not.

It's a grounding "spring" for the MCP heatsink and should be in contact with the MB tray (according to the guys at the evga forums).

I just finished modding my 780i. And by mod I mean getting it to run under boiling. An out-of-the-box test run had the MCP (southbridge) running at 90C. It went as high as 96C while I was setting up the BIOS.

Apparently, nvidia has a brilliant heat management strategy for their MCP chips which involves tons of thermal paste, and foam heat pads. Except, the foam isn't supposed to be a heat pad. After taking off the MCP 'sink, removing the misplaced foam spacers, bending the heatsink so it was flat and flush, reapplying a reasonable amount of thermal paste, and painstakingly reattaching the MCP heatsink, I am now running between 60 & 70 wishing for a LC solution.

And from what I'm reading at the evga forums, I'm not the only one who got a board where the foam spacers were misplaced and making contact with the northbridge and southbridge chips.

[Robilar]

My MCP runs at around 50c lucky I guess.

Here is a mod I did for the NB cooling fan on the EVGA (which sounds like a jet engine). See post #3

I used an antec spotcool

[tet5uo]

I have an XFX 780i on the way whenever NCIX gets more stock in

Was out of stock by the time my order got processed...

Have a qx9650 with no mobo to live in right now and it's a sad CPU.

[JacobF]

The spring is on some boards, it is for EMI.

Also, EVGA will have an 8 phase/solid state cap version soon

Uh, glad I didn't pull the trigger on the original 780i. Will supply be better then stock for the current board?

Here's she is...

I like the NB HS and fan setup. I also like its blackness...Oh well sticking with my regular cap version!!!

[Justifire]

I realy like the idea that you can have tri-sli and some sort of watercooling for the southbridge.
Altough it isnt direct, its a lot better than aircooling only.
On the other hand....heatsink with active fan on the SB (VC-RE) and apart waterblock on the NB might give better cooling performance.

Theres no waterblock on the SB....Did I miss what you meant?

[seamumc]

I believe the SB sink is part of the water block, at the least it runs to the water block. IOW it will be 'cooled' using the water block.

If you look at the bottom pick, you'll notice that the fan on the heatsink overhangs the first video card slot. No way a video card would fit in that slot. Of course these are early pictures of samples.

Nope. I have the regular version of this board, same heatsink. The SB is definately not watercooled by the NB heatsink.

Also, it doesnt look like its covering it up. Its damn close, dont get me wrong. But you have to remember that the card is only 1-2mm taller where it plugs into the slot (the middle of the slot, not the top). It may be a problem for some after market solution, but looks ok for stock cooling.

[seamumc]

JAS i don't think we're talking about the same board. EVGA just announced the 780i FTW. There is a combo water block/air cool heat sink on the NB. Look at the pictures for the 780i FTW closely, you'll see the barbs they are partially hidden. Its also described in the press release for the 780i FTW.

[Justifire]

As far as i can see theres a connection (maybe a heatpipe underneath the cover ? ) from southbridge heatsink to northbridge heatsink/waterblock.
So yes, you missed what i ment
