EVGA NForce 680i SLI Motherboard

[Charles Wirth]

I am running 800/1T if i go up to 1Ghz+ it will need to drop to 2T for stability.

[-n7-]

Sounds like a nice horror story thus far

I like the idea of unlinked RAM though, so when there's a few more mobos to choose from & the prices drop from their heavens, i might consider one of these 680i babies.

[wtkprol]

does it natively support QUAD SLI??? (7950x2)

And would 7950 x 2 be competitive to 8800gtx x 2??

I should have some results up next week if one of my people dont fail me.

[maxxxxel]

yes , but when apply , ntune needs to reboot ...

Is it designed to do that, i thought the it would do the changes on the fly

I was going to get one of these boards, but now i will wait. its seems people who have ordered the board are finding OC'ing more difficult than those who got samples of the board, it could be a bios update issue.

One could spend a few days playing with memory timing and ratios alone.

And that's why I finally pulled the trigger on one from ClubIT. Nice to see Perdro's screenie with the memory options. I'm a little wary of the FSB holes you mentioned and I'll probably get another 680i when a winner emerges from the OC friendly mobo makers, but in the meantime this will be fun to tweak and prep a bit on. Next weekend I should have the mobo unless CLUBIT is serious about the 5-7 days shipping even though we're both in the Golden State California..

[Phil The Greek]

on intel you always run 2t

Are you sure about that?Its the first time I hear that

[Phil The Greek]

We accidentally set a 6300 CPU to 3300Mhz - 550 FSB x6 - while waiting for Pedro to pick up the mobo. Orthos stable.

Please forgive my stupidity, didnt take any pictures or screenshots.

This motherboard is the real deal. I'll have some registered results soon.

I also tryed enything between 2100 to 2280.Always got a reset.Only works between 1700 to 1760.Maybe its my cpu(E6600),but I will not change it because the mobo doesn't like it

so what is the max fsb@1T

So whats the dea lwith the backplate and cap.?

I have the backplate on, system is running fine, forgot to check if its touching tho

[Pedro Rocha]

Mounted on the VapoLS - update with some 3D benching in post # 2

Depends on your memory, running some "beta" OCZ at 910 1T at this time.

It is until they fix the drivers.

[BulldogPO]

Should I wait till Abit IN9 X32-MAX or buy this as upgrade to my Asus P5W DH?

[Senater_Cache]

well the chipset hasnt exactly fully lived up to its hype with the current bios's.
Abit claims this and that, but yuo should wait for a review of the abit.
Abit is scheduled for @1 2007 (january actually) so you will be waiting.

[Phil The Greek]

Till now from what I have been reading,the max fsb has to do with the cpu u are using and it might be alot deferent in same model of cpus.Thats really strange.

[Charles Wirth]

Pedro, try this.

Unload the video driver and then reload it, doint touch anything just bench. I think you are taking a pretty good size hit on nature.

Thanks Charles, I will try that ..

But I already notice that Nature must be the first test to run - if you run anything after windows boot the nature score is heavy penalizade. So that reload drivers tweak makes sense, must allow Nature not to be the first thing to run after boot up.

BTW : Re-run 2001 with just the very basic LOD tweaking and here is the result :



Also as you can see, if ATITool 025b16 pre7 is used you already see the correct memory speed and not half speed as in previous versions ..

[IvanAndreevich]

Put that CPU on cascade and let's see 100K

This is the dream board for 775 now. I hope the 650i boards will be more affordable but almost as overclockable

That's interesting. On AM2/NF590 I and many others walled around ddr800 or so. Blamed the memory controller. Seems to be an Nvidia chipset limitation.

[Charles Wirth]

You dont have to reload the driver each time, just wanted you to start at a known reference point of best nature before tweaking.

Good to see you picked it up quite a bit and looking forward to cascaded cpu.

so how is 3D/sPi performance clock for clock vs. 975x?

[BulldogPO]

so how is 3D/sPi performance clock for clock vs. 975x?

This is my concern also..

[Pedro Rocha]

In Superpi the performance may be a little inferior, but I am not a big fan of superpi.

In 3D, specially with Nvidia graphics cards, the performance is superior given the full PCIe 16x and the Link Boost architecture.

But these board just came out, of course the developement stage of the 680i and the 975x can not be compared

However the unliked memory feature have a lot of potencial for superpi fanatics, since allow using exactly the sweat spot for CPU and memory speed.

HI! Pedro
What is the max fsb stable for this motherboard?
I have a E6600,and with my p5bdeluxe the fsb is 520

[OldGuy]

@ Fugger and Pedro...The two of you are using (or have used) 6800 Extremes. Do you notice when first booting after making bios changes that the indicated bus speed is off when using a multiplier other than factory...i.e on an E6600 if I set FSB to 1850 as an example (462mhz effective) at factory multi of X9 it boots and shows in the post screen 462 X 9 (4158mhz net). If I change the multi to X8 the post screen shows 518 X 8...change to X7 and the post screen shows 593 X 7 and change to X6 the post screen shows 692 X 6. The bios is trying to maintain the overall system frequency od 4158mhz by adjusting the bus which in turn creates some crazy FSB numbers...

I think this is why we are seeing the "dead spots" which fugger has mentioned (and I too have seen plenty) as the system simply cannot boot at whatever frequency it is generating. There is a huge range that simply will not post without going to safe defaults so you can't see what the bus speed is that it's trying to use during boot. 1850mhz happens to be one that shows the crazy speeds during post but will not boot to windows on my system...

Just curious if the unlocked multiplier on the 6800 generates the same results.
