I couldn't resist buying them from Newegg for $114.99. That included an instant savings of $35 and free 3-day shipping.

I have alot of issues with mine. I can't get it to boot in between 3.68~ and 3.79~ after that it opens up a little then I can't get it to be stable though. I can push 3.6 all day stable with a Q6600 G0 by the way sorry. I am able to stick that processor right back into my other MB, a GA-P35-DQ6 and crank it right up to 4.15Ghz with out a problem?? I have messed with the +..mv settings and found that with a +105 setting on all of the 0-3 that I can sort of get it stable @ 1700 but, 1650 will not go with +85mv or +105mv?. This board is freaking wierd. I am about to take it back I swear.. Does this VDROOP mod do any good? Is it really worth the hassle? I appreciate input on this. I will tell all the settings I tried which were like everything under the sun. I am a pretty avid overclocker so,,.
ok guys, just had another 780i just die out of the blue... rebooted after installing updates and the machine is stuck at the first post screen. This is now 3 boards for me in various builds that have kicked the bucket. Mind you now 2 of them were for builds for other people with no overclocking.. mine was.. but it was in spec in terms of overclocking. I went back to my trust maximus formula board and I am currently playing with a 3870x2.

Removed the NB assembly and removed all the foam spacers...applied A5. Replaced the NB fan with a 16mm Spire CPU fan/Antec Spot Fan on the Mosfets. Spire is blowing down to stop moving the heat of the GPU's up.. temps of NB now range from 56C to 65C which is acceptable.
Just a little study I did with 8GB of ram on the 780i.
Here: http://www.xtremesystems.org/forums/...d.php?t=177712
I've got this board with 4GB Crucial BLX Tracer 1066MHZ, QX9650 and dual 8800GTX's, and I am getting BSOD after BSOD with SATA DVD drives. I take the Optical drive out and the system works fine. I NEED SATA optical, otherwise that nice HD/BluRAY player will just be sitting there.....
Anyone have a fix????
Whats the purpose of people setting there command rate to 2T? I thought that 1T was faster and as long as you are running just two sticks why would people set it to 2T? I have this EVGA board and 2x2gb set of memory set to 4-4-4-15 2T.
Hope you don't take it personal, but I came back here to see if there is any new info and saw that in the first post of this thread. (Not sure if that was there when I first posted about it, but I just saw it today) I am sure that your experiences were genuine, but you're overly generalizing. 780i board runs hot, and there is no reason to recommend unnecessarily high voltages. Less experienced users might just follow what's stated without testing it out themselves.
I have run Prime95 64-bit BLEND, just for you. (OK we're getting personal ;) )

Blend, right? And SPP voltage 1.4V. While I am not using a quad-core, I am using 8GB of RAM, along with two video cards and 2 x 250GB in RAID0 / 2 x 500GB in RAID1, so my SPP/MCP are quite stressed. Still, I didn't try 4GB (2 x 2GB), but I might even be able to get by with even less voltages for SPP.
What I'm trying to say is that everyone's configuration is different and every board/SPP will be slightly different. And temperatures can also make differences. A few just off my head:
- It's very possible that SPP might need higher voltages for quad-cores
- If you run NB fan faster, or swap the fan with a better one you might be able to lower vSPP
- Even for the same 4GB configuration (2 x 2GB), it's likely that DDR2-1000/CL5 with dividers requires more voltages than DDR2-800/CL4 under 1:1. And different memory ICs could have different characteristics.
- And so on..
Again, I have no doubt that your finding is legit for system configuration similar to yours. But you have to be careful when you generalize it beyond that because as you can see, not everyone is going to use the same CPU, memory, GPU, or even cooling.
Hopefully my post will be considered a contribution to the thread, not a personal attack. This was quite an effort on my part because I hate Blend! :D
From my observation, the performance difference between 1T and 2T isn't as big as in 680i. 680i performed meaningfully better with 1T than with 2T, albeit mostly noticed in benchmarks.
It looks like achieving 1T is easier with 780i, but the performance improvement isn't significant. I'm guessing that NV loosened the internals for better compatibility. I don't think it matters a lot since current trend is going towards capacity than performance, when it comes to DDR2.
Hi everyone, i just got my new eVGA 780i board after 5 days of total horror with the Asus P5N-T Deluxe and my E8400. So far im having some problems getting it past 4 seconds of Prime95 alone at 1800(QDR) 1088 on the memory with --1.34 on the chip and the CPU FSB at 1.4v, SPP at 1.55, MCP at 1.6, SPP->MCP at 1.5-- and thats all i can remember off the top of my head. OCCt fails as soon as i press start (Yes the chicken noise scared the :banana::banana::banana::banana: out of me) Im using Vista Ultimate x64, Now my question is what is the recommended setting for 4GHz and this board? I noticed on the first page the first post says 1.5 on the CPU FSB but i can only go up to 1.4? Im using the latest bios P03.
Also, is the Vdroop mod really necessary? I'd rather not start penciling my new board within the first day, but if it must be done so be it. What are you guys using to monitor your NB and such temps with this board? I have been a dedicated Asus but the P5N-T was just a piece of crap. I couldnt even read voltages in the bios, oh man it was terrible. Can you guys please post all your voltage settings if your 400+ on the FSB with a E8400 or something like that? Im not sure if its the Mobo just being a biatch with my chip or what, but man i've been fighting for the past week with the Asus and im not returning this eVGA so i hope it turns out good :)
Oh and PS - How do i get Everest to show me the MCP temp?
Furios, try 1760, 1780, 1820, 1840 instead of 1088. Memory Linked-Synced first. You want to find out if there is a difficult spot in terms of FSB.
GAR, I don't know what to say. It's kinda eye-opening.
I can't get my board to turn on.
I hooked it up properly.. the blue light turns on.. but the power button won't turn on the computer!
I know I had it set up properly!
Even pressing the power button on the board does nothing.. no fan spinning, no hard drive noises.. nothing.
EVGA technical support was horrible. He kept yawning and laughing with the guy in the cubicle next to him!
I dont even see an option for NB volts... is it called something else?
This should give you a clue...

nForce SPP
Oh i see, For now i have it rock-solid at 3.83GHz with 1700(QDR) with linked and synced at 850 on the memory, right now im tweaking CPU voltage, got it down to 1.325 (1.26-1.27 according to my Everest) with Prime95 and OCCT at the same time. Gonna let her go overnight and then when i wake up tomorrow im unlinking the memory and gonna crank it to 1000, Might have to wait for a few BIOS updates before i can achieve my 4GHz, but save that for another day. Night everyone, waking up in 4 hours to check haha.. Cell phone alarms for the win :up:
Oh yea, and i give major props to the board. I manually set my CPU and memory voltages and left the rest AUTO and everything is REALLY nice, The Asus board is a piling piece of silicon compared to this one, I love this board! Wooo!!
So what is the cpu fsb? I understand the the cpu core is the one we crank for the cpu but what about the cpu fsb?
no, it's the other way around.
SPP is the north bridge
MCP is the south bridge
just remeber.... S=system M=media
The reason why I ask all this is for better understanding... Currently I just do what all you do and it works... crank this up and then that... and bench check it with prime95. I want to understand a little bit more about some of these "things" we are giving volts too.
Also if anyone is interested in enlightening me... why crank pci-3 mhz to 125? and why crank spp mcp ref clock to 250mhz?
OH! So i had it wrong, i was cranking the voltage on the Southbridge.. hahaha im a tard. Anyway that solves one error, thanks.
CPU FSB is the CPU VTT, It says it in the Details in the BIOS. Not sure what it does but you have to balance it with the Vcore
I havent touched the SPP MCP ref Clock yet, im trying to get this Vcore lower, it just failed at 1.325 (1.26-1.27 underload) so im back to 1.350 (1.30 on load) So this is stable pretty much. I have a good chip, 1.1125 VID so this baby can do it. I'd leave those SPP MCP ref clocks alone, and the PCI-3 I havent touched either so meh, I dont really think it'll do much in terms of gaming performance, the Ref clock from what i've read gives you a few more points in benchmarks which doesnt mean much unless your a hardcore benchmarker trying to go for records and stuff.
i had my e8400 @ 4.32ghz @1.38v(actual, set 1.4v in bios) on my pencil modded 780i(fixed vdroop). my q6600 ran at 3.6ghz @ 1.5v and 3.9ghz @ 1.56v
the NB was set to 1.5v, ram was set to 2.3v(your's may be lower, and probably should be). everything else is set to auto.
Im scared to do the Vdroop mod because this is a brand spankin new board. How were the temps? Im using the Zalman 9700LED which is a great cooler. Underload atm im at 51C with Prime and OCCT going
What do you estimate for 4GHz Flat? (1780 QDR)
This is just my opinion. Look at this image of the 780i chipset...
Attachment 72742
CPU Core: CPU
CPU FSB: I'd bet this controls the signal between the CPU and SPP.
Memory: Memory
nForce SPP: The voltage that controls the SPP.
nForce MCP: The voltage that controls the MCP.
HT nForce SPP <-> MCP: The voltage that controls the signal between the SPP and MPP.
Do we have any descenting opinions?
Makes sense to me... I'll give it a shot... recently I've tried to boot at 2000 or 4.5ghz and it bsod' about 30 seconds into windows... what up with that? I have vista 64bit.
my 780i is down again...
cant recover from a failed oc, all i get on boot up is "ff" no post...put in for rma this is now my second time... :(
sorry to hear that, I got one of the 2 i had go down fixed as it seemed to be a bad video card, the other I just received back from rma. so far so good.
Hughy, try 1800 QDR and link and sync the ram to make sure your mobo and chip can do it. Right now im pretty pleased at 3.83 with 1.3(1.35 in Bios) on Vcore and 1088 on the memory with everything but Vcore and Memory voltage on automatic, This board can really scale well with an OC im really happy with it :up:
I'm not familiar with the vdroop mod or how to do it... please explain!
I've had this same problem and I just took the battery out for like 5 minutes and it worked like a champ! YOu may have already done that though.
Does linked give better performance or just more stability. What about those GTLVREF lanes??? What did you set those too? I am right now on 1600 fsb with 1.2 in bios... I think it's 1.76 actual in CPU-z... is this on the right track. I really havent primed for long periods just 1 hour 17 minutes.
It makes sure your memory isnt a problem -- More stability to find your Max FSB and CPU speed
yeah, battery pull didnt do it...and what a pain to pull out 3 cards to get to the battery...
evga ok'ed my rma, so with luck i might get my replacement tomorrow, but i think when i get it i will just run a single card and put the other cards in som othe rigs...
Do SLi (2). I honestly dont think the Tri-SLi is worth it, Ebay the other card you have left and call it a day
This board runs great with 2 8800GTS so i'd say 2 cards, Tri-SLi is too new if you ask me
I'm seriously looking at getting one of these since I want to get either a 8800GT or 9600GT SLI setup. I'm really worried about getting a really hot running NB however, what do you guys think are the chances of that happening? Also any issues with this board at stock speed with 2x2Gb PC8000 memory? Sorry for so many questions.
Do the 8800GT, 9600 is for the midrange, 8800GT, i would say is closer to high-end then any of them. My NB doesnt get very hot at all to be honest, especially if your staying at stock. I'd say go for it man, these boards rock :up:
Thanks, reason was I wasn't sure what the price difference would be here in New Zealand but I just checked my e-mail and it turns out the difference is only NZ$50 which isn't enough to justify 9600GT. May I ask exactly how hot at stock volts under load please?
Thanks
My SPP is idling at 51c, but its not at stock, i have it at 1.55
yeah, i agree the tri-sli is way overkill and not worth it at all.
Tri-SLi can be beneficial in the future, but atm i'd say no, No games need 3 Ultra's (This excludes Crysis because its, Well... Crysis) even at 2560x2480 or w.e that resolution is.
Guys, what does it mean if im getting lock ups in the bios. All i did was set the FSB to 1780 and linked / synced the ram. I have all voltages on Auto except my CPU and Memory. CPU is at 1.375 which gives me 1.32 under load in windows. Uhmmm thats it, not sure what else to do. besides get a new powersupply, which i think is the culprit. Any suggestions?
yeah, a new power supply would be one of the first places i would start for a hard lock up in the bios, or it could just be the mobo...
Im not sure if the mobo is just being flaky but its so stable that its hard to believe, maybe auto on the SPP isnt supplying enough voltage to keep it stable in the bios? because in the BIOS its underload so maybe its causing the hardlock. Im scared to play with it like that after reading you guys blowing up mobo's while OC'ing. Freezing in the BIOS scares me bad
I got my 780i about 2 weeks ago.
I've gotten my E6850 to 3.8Ghz so far. (Haven't played much with it)
Although i did have some problems getting my ram "Crucial PC8500" to run at 1066mhz. But i got that fixed, i hope.
I'm still in line for the upgrade as well.
In line for an upgrade for what? Anyway i think im going to stay at 3.83 until i can get a new CPU cooler, Powersupply and get a new SPP fan. I found a good thread over at http://www.evga.com/forums The NB is exactly 60x60 so i can fit a nice fast 60mm fan on that b aby :up:
Do yourself a favor and unlink the ram. Set the ram to Expert in the timings section and leave everthing to auto there. By linking the ram your are throwing in way to many error factors. The proper way to overclock is to do things 1 by 1. Dont try to get it all in one shot.
A new 780i board.
My 680i died from a C1 error 2 days prior to 780i promo expiring. I didn't want to leave the promo for an RMA.
So i went out and bought one, then when i get the new one, I'm going to sell it!
And yes I talk to Mike @ EVGa about me turning in a bad 680i and he said not to worry about it. They will take it :) (no charges to me other then the upgrade fee)
haha its not linked anymore, im running at 1700 QDR with 1066 on the RAM 5-5-5-15
Well it's general good practice to find the limit of everything and then really start fiddling with sub-timings, voltages and everything. That's how I do it anyway.
Same, mine wont stay stable at 3.9 So i cant figure out what the culprit is. Fails OCCT after 30min, But what i noticed is if i put alot on the SPP it will fail (over 1.5) faster then auto. but if i cranked the MCP up a bit to around 1.65 or so, it went for 30min. Not sure what else to do. I need help :(
I dont think we can be sure that the PSU is a problem without actually testing it. I am sure that 650watts is plenty.
Yes leave all the ram timings at default. You have to take this one component at a time. If the ram is set to unlinked, running stock speed,and stock timings, then you will be only working on your cpu speed. When ya get you cpu max then you should start working on your ram. Then move on to your video cards. One component at a time.
Whats your VCore for 3.9? If you're failing in 30 min then you just might need a bit more vcore. Whats your cooling solution?
When i got to 4.5mhz i was running -
1.56 vcore
1.5 cpufsb
1.5 spp
1.65 mcp
1.4 spp<>mpp
How did you get 1.5 on the CPU FSB. I am limited to 1.4v in my bios. Im using the Zalman 9700LED. Im getting the Thermalright IFX-14 soon, and 2 140mm Yate Loons or something equivalent. My ram is 100% stable at 1066 5-5-5-15 but i know what your saying.
Ok well im trying 1780 QDR (4005MHz) at 800 and 5-5-5-15, which is way below this G.skill 2x2 set, this set runs at 1000MHz, but i said screw it for now.
I copied your exact settings besides CPU FSB and Vcore, because 1.56 is way crazy on Vcore and 1.5v on the CPU FSB i cant get that, mine is topped at 1.4v. It failed within 2minutes at those settings. So i dropped the SPP a bit and took my Vcore to 1.425 (1.36 on load) and its at 7minutes so far with no problems. my question is, Why is everyone achieving such high SPP voltages when mine gets way better times and stability with auto or really low voltages? Do i have a magic board or a bad one? Why is everyone getting 1.5v on the CPU FSB and im topped at 1.4? Oh the questions :confused:
Edit -- 1 Hour and 45min OCCT and Prime95 so far, Gonna let it go till this movie im watching ends then i'll let it go overnight once im done playing. but i got 4005 at 1780QDR. I cant believe it. Woo!!!
this message is to for radical. Im not sure if you resolved your sata dvd drive burning issue but i had the exact same issue or possibly maybe even a little worse. anytime i would put blank media in the sata dvd drive to try n burn somethin it would start to spin up to speed and it would say it was writing but it would just sit there and spin forever. then when i try to cancel or stop the program my system would just lock up. it got to the point to whenever i even placed a blank in the drive wothout even trying to burn anything it would lock up. but then i tried a regular ide drive and it worked just fine.
you said you were using a raid configuration if im not mistaking, and im not sure if this will work for you but this is what i did.
open up system properties and under the hardware tab at the top go to the device manager.
then from there navigate to the IDE ATA/ATAPI controllers tree an maximize it.
then from there find the NVIDIA nForce Serial ATA Controller that the drive is on and right click it and choose to update the driver.
then choose to install from a list or specific location (Advanced) and click next.
then choose the "dont search. i will choose the driver to install" and click next.
then you choose the standard dual channel pci ide controller and click next and reboot.
and then as easy as that my problem was solved.
like i said i dont know if you can do this in a raid configuration or not cause im a noob an im not to familiar with that configuration yet. you might need the nvidia sata controller for raid but im not certain really but its worth a shot and hopefully this is of use to you cause it certainly made my day when it resolved my issue.
its gotta be an nvidia sata controller issue
Furious did you flash to the PO3 bios? Might be why 1.5 isnt in your bios. Yea if ya dont have good cooling dont go to the 1.56vcore.
Mine should be ariving in next week,
I have X38 board running my Q6600 @ 450x8 @ 1.4V
Want to do the same with eVGA 780i.. any tips pointers for first time users of the board?
Its easy to flash BIOS?, i followed link and put into a floppy for PO3.. would be wise to flash with that before i install everthing on windows?
Im on the P03 Bios, still isnt there though. Is somethin wrong :(
I figured I'd pop in and give my settings for 24/7 OC on this 780i, (XFX board)
CPU 4.0gHz (400x10) 1.44v
Mem 1066mHz (linked with 3:2 divider) 2.2v
SPP 1.45v
MCP 1.5v
FSB 1.1v
GTLref is Auto cause it confuddles me... :shrug:
Been really nice and stable at these settings so far. (knocks on wood)
I'm still using the bios this board shipped with, i'm assuming it would be the first one.
It went 7hours overnight until i stopped it this morning. Im still confused as too why i cant get 1.5v on my CPU FSB but it doesnt matter to me anyway since this is stable now :up:
I've never needed to use FSB voltage that high.. you sure you actually need it?
hey does anybody have any info as to when the new 790i ddr3 board will be released??
it should be out the second week of march. that seems to be when everything else is coming out, right after CeBit.
really that soon?!! Man i just barly got my evga 780i up. Is it gonna be woth an upgrade you think?
IDK. ddr3 and native 3way sli and pci-e 2.0. i don't know much else about it.
the second week of march is gonna be a big week if everyone keeps to their promises.
nvidia...
9800gx2
790i
?what else?
Intel...
45nm quads
x48
45nm mobile chips
it's not official but i've heard from my reps that it's all true.
i think i heard somethin about an asus formula II extreme being released for the 790i series
No its the Asus Striker Extreme 2. but i dont think the 790i is worth it. DDR3 is way to expensive and i dont think it'll make much of a difference in real gaming
the new quads will benefit from ddr3 but the price is WAY too high. the cheapest i've found ddr3 yet is $239 for a 2x1gig set of g.skill 1333mhz 6-6-6-18 kit. you could get 4 to 8gig's of ddr2 for that price.
asus and nvidia chipsets don't seem to work well together. asus makes some damn good intel chipset boards though.
but soon everything will be ddr3 and they will slowly become affordable just like ddr2 has become.
By the time that happens we'll be on Nforce 8 or Nforce 9 motherboards.
Man i cant wait for those, i wonder what they will look like :rolleyes: :rolleyes: :rolleyes:
so when are the new quads due out anyway?? Im due for a good upgrade
2nd week of march. like i said above.
I'm sorry i put in the wrong Voltage. Its 1.4. I dont have 1.5 either. I was reading from some notes i took off another thread somewhere. I remember now that i didnt have the suggested 1.5 either. That must be off another board.
EDIT: I got that voltage from the first page of this thread.
GAR? Is the 1.5cpu/fsb from the original bios?
On another note.
Has anyone tried the EVGA 780i driver update? I tried it the first day i got this board and i lost everything and had to reinstall my os. Not sure what happened there. Any suggestions?
what do you think the price ranges will be?
q9450 ~$330
q9550 ~$590
Anyone know why my cpu core voltage won't go above 1.36? I can set it higher, but it always shows 1.36 in the Current Value column when I go back into Bios.
Here's a pic of what I'm talking about.
http://starlon.lyrical.net/images/dsc00316.jpg
im excited:D
so what is the multiplier 8 at 1333 right? and is this a fixed multiplier?
yup.
i wouldn't think many people could get much past 4ghz on the q9450 though. that would require 500x8 to do 4ghz. most boards start hitting their limit around the 480-520 mark. we'll see though.
but think about it. to even conceive the thought that 4ghz might be possible on air is just crazy. but whats even more crazy is that it just might be possible
hmm...are you using 4 or 8 pin cpu power from your power supply?
and the bios holds all you other settings?
