A Detailed Comparison Between 680i SLI and 780i SLI

[cookerjc]

Different from the 680i SLI, this engineering example did not use south bridge to north bridge heat pipe system. 780i SLI only have heat sinks+fans. The north bridge big heat sink are cover both SPP and BR04 chips.

780i SLI use black PCI Express 16x slot. Different from 680i SLI's two black + one blue. We believe in the retail version 780i SLI will still using two black + one blue PCIe X16 slot and heat pipe design.

There is no difference between between nForce 780i SLI's power module and nForce 680i SLI's. Both of them are 6 phased. Every phase have one R50 and four Mosfet. Because of this, we once thought the 780i SLI mobo is only an another version of 680i SLI.


　　though they really simaliar to each other, we also can find some difference if we look carefully.

　1、Because of the BR04 needs room，so nForce 780i SLI is canceled one PCI Express 1x slot.

　2、 nForce 780i SLI using NF570-SLI MCP chip，but nForce 680i SLI is using NF590-SLI MCP chip，the only difference is their name. They have no huge difference in their functions. We will have a detail description in our later review.

　3、nForce 780i SLI using two one-digit-DEBUG LED，but nForce 680i SLI have one two-digit LED.

DEBUG LED of the nForce 780i SLI

　4、The position of the front panel connector and clear bios jumper are different.

　5、nForce 780i SLI canceled one 4Pin D type 12v power connector beside the memory slot of the 680i SLI.

Our review is coming, someone testing the mobo said that the 780i SLI's funtion are quite different from 680i SLI. Pls keep tuned.

Wow, thank you very much.

[Baleful]

Still looks like a heap of foxconn crap.

[zerazax]

Well, lets see how the features go compared to the 680i

The big thing is the 780i better be a whole lot more stable than the 680i was or else its a no go for me

[kuhla]

Unless I am missing something, this doesn't look like much of an upgrade at all! Why even give it a new name?!

My thoughts exactly. I'm tired of these craptastic Nvidia chipsets.

Wooooooo you added a 2nd chip by the NB, and gave it PCI 2.0.... please. The 680i is the most unreliable POS i've ever seen in my life. I've gone through 4 boards so far. And before you naysayers come out and say "you're just breaking your boards" shove it. The 780i won't be any different. Stick w/ p35/X38 unless you have to have SLI. For those of you who do need SLI, good luck.

[CraptacularOne]

The deletion of the 4 pin AUX power for the board is worrying. Or have they found a more efficient way of getting power to the chipset?

As for you Baleful, seems you've had bad luck with them. I'm still on my original A1 board from early this year year. The only time it's been RMA'd was for the AR to A1 swap for the quad core fix, but the other board was technically fine.

[zanzabar]

looks like nvidia is going to loose massive market share to the skull trail

[[XC] gomeler]

Just wait for benchmarks, who knows if they've done anything different to the silicon on the northbridge. Good thing I don't use SLI otherwise I'd be pissed

[Kenetixx]

Yeah doens tlook much , even looks as tho they kept the old design to save some dollars, we shall wait and see if it perfoms.

[Zytek_Fan]

That's my thought on it.

[hollo]

thousands of potentially awesome rigs owned by an average chipset?

[afireinside]

Still looks like a heap of foxconn crap.

You do realize it's AN NVIDIA REFERENCE DESIGN, right? What does foxconn have to do with it? And I don't know wtf YOU'RE doing with your 680i boards, but my EVGA 680i ("heap of foxconn crap") board is lightyears more reliable than my p5b deluxe wifi and badaxe 2 ever dreamed of being. To bad 680i is so slow

What i'm doing is using them. With a very mild OC to the processor, the boards usually last a month, then wig the hell out. Take settings back down to stock, still the same crap. RMA the deffective board, get the new one in, system runs fine for another month or so, then wigs the hell out again (constant restarts, freezes). Tell me, what the hell AM I doing wrong? No driver conflicts...... no excessive OCing...... What??? There are many others having the EXACT same problems with their boards as I am, but yah it's just me screwing the boards up right?

[The0men]

Every one keeps saying that 780i has lost the extra PCI-E 1x but wasnt that just for the ty supreme FX, it is placed further back than the other PCI-E 1x on my 680i Thats also means hopefully theyre not sound card (onboard sound) anymore... Good idea lol. The heat pipe solution was useless to, hopefully they dont use that anymore.

[p8ntslinger676]

meh im not going to upgrade boards until i need too, which is not now btw

[Borgod]

Hopefully they're still on target for a November 12th release, as my DFI 680i just broke

Since when is a 680i board more reliable than a BadAxe2?

[jonnyGURU]

No mention of the implementation of ESA on the 780i?

[Spawne32]

can i join in on the fun with pictures guys?




and i have to agree with baleful 680i was crap, and now it looks like no tremendous effort was put into 780i either, their just gona slap a high price tag on it and need 13 different revisions of the board to fix all the problems with it.

I feel the same way. I ditched my intel 975x board for an asus striker because I wanted SLI.

Well I do have SLI now, a stable computer far from it.

The led should be increased in size to 3 letters/numbers.
Also the following should be included..
RMA
LOL
;(



And of course instead of the double digits of death, it should be replaced with
I absolutely hate these nvidia chipsets.. I have gone through so many boards and they are just pure garbage.
The gfx cards are great but their motherboards are crap. I'm suprised these boards don't start with a wick and a match

[naokaji]

Instead of the usual advertisment on the Retail Boxes they should just print on how the Rma process works and where you have to call (or directly put shipment address on it)
