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

[malik22]

Too much work, try an antec spotcool instead. Better temps (it has a 3 speed controller) and installs in 10 seconds).

Robilar thx for the recommendation but they dont sell those in my country Since your have a Ultra extreme like me do you think this fan will fit?

Couldn't find one, so here's a Template for the key BIOS items which may help others to share their settings. Although it is an XFX BIOS it is running on an eVGA board so maybe some differences between the two.

thanks, with those settings (except ram timings) i was able to hit 4MHz's

OK, I am SERIOUSLY considering running an EVGA solution, since my second RMA on my Abit 680i is not working, STIL. I am so sick and tired of getting blocked by bad hardware / incompatibilities, im just done with 680i

HOWEVER, I also have a spare BFG8800GTX sitting around that I COULD OC with NVtune and dump it on the new board along with my OC 2s....so I am setup already for SLI. However, I need to know the following:

Whats a good PSU that has 6 independant 6 pin rails for Tri-SLI?

I think I am going to pull the trigger on the new board and a new PSU here soon, say in a few hours. I have a few more things I am oging to try to get my current hardware configuration up and running, but I am not hoping for the best. Worst case, I get my new board and get everything up and running by this weekend for testing.

TYIA for the PSU suggestion. And oh, BTW, I want something in the 1200 watt range just to be safe!

i got the tagan bz1100w psu, and it is awesome. if you look on nvidias site it is also certified for tri sli, although im using dual sli. it has 4x6pin and 2x8pins so you dont need any adapters to power the third card. cables are also modular

edit: the 8pins are actually 6+2 so you can use them as 6 pins

Ahhh, IC now. I was wondering about that when I was browsing Nvidia's website and saw no "Tri-SLI" certified PSus. That explains it. In my current setup I have a Coolermaster SLi rated 850W PSU, and I love it. Might go with the upgraded Coolermaster and see how that works, or I might not. Thanks for the heads up!

As for the BFG 8800GTX and my 2 BFG 8800GTX OC2s....I SHOULD be able to run tri-sli with those three cards, assuming I use NVtune to OC the regular 8800GTX to the OC2 card specs, correct?

--Skrips

[lopri]

i wont believe you enless you show me an 8 hour prime shot, blend.

With regard to this..

Well I realized that Everest didn't show the vSPP in Windows. (Vista 64-bit) What apps can I use?

Edit: OK this is the best I could do for now. Also note that I'm running 2 vid cards..

hmm.. i think that would work, but im not sure at all. you might wanna ask that on the slizone forums or something.

Well, though I haven't played around with the NVtune tools, as far as I know you can clock the boards however you want to. And, since the 8800GTX cards and the 8800GTX OC2s are basically ideantical except for the factory overclocking, I would assume that overclocking the vanila 8800GTX to OC2 specs would in fact make it an OC2...

Then again, I might be wrong

Look at your screen shots, you are using only 18% of your memory which is what your OS is using, run blend to it stressed your NB, then post some screen shots.....also you are running only a dual core cpu.

That's kinda off from your original claim. I never said that I was running a quad and neither did you. All I remember is that you said it takes 1.5V for SPP to run 4GB of RAM and I said that's not the case.

Although I'm not around here too often, folks who know me that I prefer LargeFFT for various reasons. I also have ran 12 hour Memtest with 8GB of RAM but unfortunately there is no way for me to show you the vSPP in a screenshot.

I don't have any reason to lie about this nor time. You can move on thinking I'm mistaken.

[GAR]

Anyway, when you are trying to prove me wrong, dont show me a cpu stability test and tell me your ram is stable........i have tested more than 5 780i's and they all performed equal.

[lopri]

You're being funny now. I am sure that you know the difference between LargeFFT and Blend? If you ask people who work in the industry (like OCZ Tony), they will tell you that LargeFFT is a good barometer for memory controller stability. For pure memory testing, we have another industry standard called Memtest.

There are other reasons as well, but one big reason I don't like Blend is that I can't use the system while it's running. But I guess I will have to run it sometime later just to prove you wrong. Or should I be concerned that I don't have a quad-core?

And five 780i boards? Do you work for EVGA?

i know large is for memory, thats why im telling you your screen shots do not validate your point because it is small fft's

[ncsa]

Glad it help out .. although I do hope you got a wee bit more than that

4GHz is a good place to be, keep on going up

Did your 5 boards have exact same max FSB headroom ?

[GAR]

Did your 5 boards have exact same max FSB headroom ?

Yeah, all of them died around 470-480......this is with my G0 Q6600........and all of them acted exactly like each other.....it was like they were all clones.

[eva2000]

Did you try that Q6600 GO on P35/X38 to see what it's max FSB is ?

My Q6600 L725A903 G0 does 501FSB on Asus Blitz Formula just wondering if I'd be too limited on eVGA 780i ?

My Q6600 booted into windows at 500fsb with my x38, but was not stable....i dont think the 780i is going to beat your blitz

NM man, whatever works for you.

[Psycho_eddie]

Ive bitten the bullet and ordered a EVGA 780I mobo for future 8800ULTRA purchase to make SLI


Mobo should handle 450FSB to make 3600 Mhz (x8 multi) on my Q6600??


60x25mm fan on NB wouldnt cause issues with a Thermalright 120EX?


First EVGA mobo too

[gastoncapo]

im bout to pull the trigger on this mobo too..i haven been without a pc (mobo died) for much too long now :P

yes, or you could easily do 400 x 9

as for the second question, i dont think u will have any probs.

Questions:

I just sold my Asus M2N-E SLI + CPU, going to move my Asus Striker Extreme into that box with an E6600, 680i + Q6600 = crap clocks.

I don't think I'll wait for the EVGA 780i FTW edition, if anything I can do a step-up later.


Now, I have 2x 2GB OCZ Reaper, I was wondering if anyone has had luck with 4x 2GB with 400MHz or higher FSB?

I'm NOT looking for extreme overclocks, but I want AT LEAST 9x 400MHz for 3.6GHz on my Q6600.


On a side note, is 2x 8800GTX really that much better than 2x 8800GT? I have one of each card right now, and I'm not sure which one to buy next.

hitting 400mhz should be a walk in the park...
