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

[Reinvented]

Ugh, my 780i board is misbehaving. I got it from MotherboardPro, and just now began to set it up. It had some nasty sticky stuff on the backside, and I'm not sure if that was causing it to short or something. I've gotten all sorts of Post Codes, and I get absolutely new video.

RMA time you think?

PS - Thank god I still have my 680i.

Anybody experiencing the graphic card artifact problem that seems to be more chipset related thats talked about in this thread?

Quite thankfully, no.

I went through four...yes four 680i boards and I pray each and every night that I never have to experience that again. So far, my step-up 780i is working quite nicely. I have a QX6700 and haven't tried overclocking yet. It's been together and working for about 10 days.

hi all.

I've some problems with 4 sticks memory, and with first BIOS mobo boot but Win crash and with P04 mobo don't boot!

I tried both 4*2gb Vitesta Extreme 800+ and Cell Shock D9GKX 4*1Gb.

P.S. : like my rig, I've a XFX...

[flashnc]

just did the vdroop mod...before it took 1.525 bios.which gave me 1.472 idle.1.448 running pi and was hitting 68-70c temps @ 3.6 on my xeon ( which will run 1.39 stable normally) ( i just started there to see the vdroop and temps)
now after the mod, and testing and adding a touch more pencil at each test, im @ 1.4 bios 1.4 windows @ idle, and 1.392 load both cores and temps now down to 54-56 load ( yea need to lap this one but im waiting on my 8400 first to take the system apart) thats a vdroop of only .008 load from bios, so it looks like it pays to pencil then test till ya get a really close vdroop to bios...cant wait to get the 8400 it will be here wed....

supplying enough voltage to memory?

I have come to the conclusion that I will end up doing this. I have a 0.10V droop from bios to load in windows. It is really messing with my overclocking attempts.

[Celcius]

Doing the vdroop mod made a huge difference for me

[op1e]

I've tried a couple times and at first it doesnt seem like its doing anything. Using #2 pencil. I think I knocked it down though, from a .5v droop to a .3v. Just seems like the pencil is too smooth to lay anything down on metal. Also, my MCP is hitting 70c running Orthos right now, should I be worried? Idles in the low 60s.

One important question if I could please get help on this, do I have to flash the P03 bios to run my GSkill at 1000 mhz? Orthos fails blend but not cpu.

supplying enough voltage to memory?

Yes....

I hope in next bios release.

[Hughyhunter]

^^ kinda frustrating how 4 sticks cause so much instability huh? Maybe try running them at below stock speeds.

guys i just finishing my new gaming setup , running 2 9600 PALIT SONIC/Q6700/Kingston DDR2 1066, Nforce 780I.BFG 800W PSU,
whats the best way to load windows ? with the 2 videocards installed or only one? and debating on what windows to buy windows vista 64bit? windows XP 64 bit? or 32bit?
thanks in advance

[Hughyhunter]

Dont worry about having vid cards installed... has nothing to do with anything. Memory too... some people think you cant load windows with 4gb memory. I did!
I have 64bit. It's been a headache! I dont know if it's due to the stability issues with 64bit or just Vista itself, however it does recognize all 4GB of memory. I have read though many places that 64bit will use more of that memory so it doesnt really make much of a difference unless you are using 8gb of memory. I am happy overall and still if I did it again would get 64bit... not to say that there is anything wrong with 32bit it just doesnt give you option for 8gb of memory (like I'm gonna need 8gb anyway!)... Just my $.02!

ok guys...oem Q801A290 batch.( tankguys) nothing special...4050 @ 1.400 real volts loaded, occt passed, load temps 56... idle 34...32m dual pi stable

ran 3600@ 1.257 i think it was, not positive on that one , id have to go back and retest the low for 3.6...was great till then....the it started taking the volts to move any higher, sizable jumps till the 4050 at what you see above. but great temps with a tunic, gaming @ 43c-44c...so im satisfied, finally..in the 4ghz club...( alittle late, but what the hell...im there

The EVGA board is on sale @ Motherboardpro for 227.99!! http://www.motherboardpro.com/EVGA-1...ard-p-468.html

Sweet price considering what newgauge is getting.

Hello guys.
I have a E8400 on my EVGA 780i SLI board. What's the maximum fsb you have reached with a 45nm dual core cpu? And what are the bios settings for that fsb. Bc I can't seem to pass 500 mhz. I think 790 board is way much better in max. fsb.

[Hughyhunter]

I've never tried to go above 500mhz. However when I did get there I was never out of the "red" in bios voltages. So I assume that I can squeeze some more out of it. However I use Vista and it seems to BSOD a lot whenever I go above 450mhz with 9 multi.

[Maxfly]

wow the vdroop with a c2q on this mb is unf***ing believable!im getting .12 droop underload...with a c2d it isnt very bad but this is terrible.i have to set 1.55v in bios to get 1.43 actual :/
time to do the pencil mod.

[Khaotic]

The max with my E8400 is 450FSB with all settings to AUTO except CPU Voltage which is set to 1.35 in BIOS.

I am a firm believer in the waffer placement theory - somebody here made a post about it, and i used that theory to hand pick this CPU at Microcenter. It is supposed to go something like; the last two digits on the PCB relate to the CPU's core position on the wafer. The closer to 00 the closer to the center the cores come from. My CPU is a 05.
I gets to 4050Mhz with only 1.35 volts (VID: 1.1125v / Tj: 105) and on water the cores idle at 38 and on Prime they reach 54 holding Orthos.

Anyway, I have made a few attempts to go over 450, but haven't tried very hard. I'm more curious to see how this board does with a quad core.

[politenessman]

525 x 8 with an e8400. vcore 1.45 in bios. spp = 1.5v, mcp = 1.55, fsb = 1.5v, ht = 1.4v. p04 bios, v64 sp1.

[[XC] NetburstXE]

Does the EVGA 780i have the pins on the motherboard for doing a BIOS reset as well as the built in switch? The reason I am wondering is I am planning on making an external CMOS reset switch, but realized that the mobo may not have the pins required.

[M@deira]

Test Vdroop Mod pencil.. =)

Below the data from before and after the Mod

No mod.
BIOS -----------> 1.368v
Windows ------> 1.312v
Full -------------> 1.288v

With Mod
BIOS -----------> 1.368v
Windows ------> 1.344v
Full ------------> 1.344v

Below some SS proving Vdroop after the annulment of the mod.

System in Full


System in Idle


Now that my system more stable

Guys i have read the post..
but it wasnt clear for me if it is worth buying this motherboard.....I broke down 3 asus mobos the last 2 moths..One p5w and two p5e....so i am in a dilemma of what to choose.....Asus p5e again (i dont want......) , e-vga 780i , or gigabyte x48 dq6....
I am bored of not having a pc for the last two months.....i just want something that works fine.....(and in a moth i will start o\cing again!!!!!)...

If you want SLI this board is the way to go. If you dont care for SLI and have no plans for it the P35 or soon to be P45 will be a great choice. If you desire Crossfire the X48 or the 790FX are good choices also.

[ed_hunter]

Ok.....
Soon i will buy one 8800gt...so i think that the evga will be a good choise..... hope it works...

[Maxfly]

finally did the vdroop mod...WOW!what a difference!
before droop mod(rig in sig).
bios-1.55v<---couldnt get 3.6 stable with anything less :/
idle-1.47-1.48
load-1.40-1.41
after
bios-1.40v
idle-1.40
load-1.41-1.40
priming at 3.6 for 2+hours.friggin awesome.
tested at 3.0 with 1.225v(VID)with the same results.hardly any droop at all
not to shabby,went from .15 droop to nada.if you havent done it...do it!
