Official eVGA 780i Discussion/Review/Overclock/Guide Thread

[froste]

I'm having a strange problem. There is only one PCI-E slot in bios (slot 3) I have 2 GTX's installed, and a 3rd scheduled for delivery tomorrow. The 2nd GPU appears to be seated good, so I'm kind of stumped.
As far as FSB, I've made 3DM06 runs up to 1700MHz so far, still tweaking to go higher.

Update: 12/20/2007
In the BIOS under "Advanced Chipset Features" -> "System Clocks" there will be an option that states "PCIe x16_3, MHz", this option sets the speed for PCIe slot number 3, which is the PCIe slot in the middle. PCIe x16_3 is PCI Express 1.1 compliant and is controlled by the MCP (southbridge).

I just picked up one myself, playing around at 4ghz with 2 8800gtx's. Should i go for another one?????

Hey Joe, is 1.365 set in the bios? If so what voltage are you getting under load after vdroop?

3 way is only about 7% faster then a 2 way, think of it like 3 chicks in your bed... only two can do so many things, where as the third will sit motionless unless needed to perform....

I beg to differ, you have one penis and two hands, 3 ladies is just fine.

Well ok guys i know we can do more with 3 chicks, but the point was the third card is only 7% faster and a third chick may be a 600 pounder.... bahaha..

right now I have it set to 1.40625 in the bios and it vdrops in windows to 1.38 and when i stress test it with OCCT it goes down to 1.345, so far so good, I am trying to see if there is a voltage regulation feature in it like the Asus Maximus Formula had, with that board I would put 1.3625 in the bios and it would stay around that voltage.

[NaeKuh]

ummm im just curious.

How are you guys wiring 3 GTX's. The most ive seen a PSU have on PCI-E was 4. You would need 6 or 2 more, and most companies dont recomend you plugging the PCI-E via adapter though rail.

My enermax galaxy DXX is modular, I have to just plug in 2 more PCI-E cables for the new card.

ok guys, anyone else get the A0 error while overclocking????? it boots, then when i go into the bios and come back out, the system hangs and i get an error reading A0, thanks.

None here.

huh is the i780 already released or did u got a ES sample, or I obviousely missed smtn:X, anyways pretty curiouse what the results are

Been retail since monday.

MIne will be here tomorrow...

SUBSCRIBED!

aith keep posting

Here is my setup now:

[Aivas47a]

Quad core (esp. yorkfield) results?

[pumbertot]

Quad core (esp. yorkfield) results?

waiting for same. also it was more than 7% from those triSLI Crysis benches, wasnt it roughly 12fps on 1 card, 24fps on 2 cards and 36fps on 3 cards? surely thats closer to 100% for each additonal card? thats will res full and AF/AA full of course or was I just dreaming of those results?

[Leeghoofd]

CornerJack can run his Yorkfield at stock speeds though changing multiplier isn't an option on the Asus variant, apparently this reference board can...

[Gunslinger]

I don't have any SLI results, but I have made single card runs at 4.4GHz. The CPU and all its functions works great so far.

[Maxfly]

any max stable quadcore fsb results yet guys?

[JAG87]

any max stable quadcore fsb results yet guys?

waiting for stupid ncix to ship...


grrrrr

[GAR]

can someone test their board with a q6600 please to see if they get the A0 error while exiting the bios at fsb higher than 1700.........the system boots when i shut it off and on again, but when i go into windows and restart i get a hang at A0 error code, also going into bios and exiting does this as well.

That's two times in this thread you've posted bogus or just vague information so I had to reply: where did you get the figure that the third card in a triple-SLI setup is "only "7% faster"? Maybe you were just trying to be funny, but every site that's benched Triple-SLI has noted great scaling (about 2.8x that of a single card) especially in cases of high resolutions (which is the whole reason those of us bothering to buy a third GTX or Ultra are doing so - for 24" and 30" screens to run at native res).

I put together my 780i based system last night finally after UPS dropped everything off including third GTX card; I fired up Company of Heroes 2 with Triple-SLI'd GTX cards and at 2560x1600 was in fact getting about framerate between 2.8x and 2.9x what I get with SLI disabled.

As for Crysis, current bench figures are nearly useless since Crytek and Nvidia are still optimizing the game for Triple-SLI so until that's final there's not much to debate.

I can say that, coming from an EVGA 680i with a Q6600 and moving to the 780i, things seem way more stable at the same frequency (3.8 on water and memory at 1100mhz) but ofcourse I'll continue to evaluate over time.

[joe.denice]

I agree, it seems like they have fixed some of the issues... but its still to early to tell.

[Leeghoofd]

do these 780i boot the CPU at 400FSB ? would be nice to run my QX6950 at 10 x 400...

Yes, I will post some prelimary results in a few minutes. I have an ES Q9550 (YorkField) running 460~FSB.
