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

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

...about 1200 or so points in 3d mark 06

I noticed you have 8GB with a Q6600 on the 780i also! What are your RAM's rated at and what are they set it? May I have your BIOS settings?


Thanks!

Mobo should handle 450FSB to make 3600 Mhz (x8 multi) on my Q6600??
60x25mm fan on NB wouldnt cause issues with a Thermalright 120EX?

The board should do 450fsb, but I would play it safe and do 9x400 to put less stress on the northbridge. As for that fan, it will fit fine, its very close but it will fit. I opted for a 60x15mm fan and run it at 50% and my temps dropped about 4c on average now.

rams running 450 mhz i am not sure of my bios settings i am at work right now, but a few pAGES back i followed someones setting for their xfx 780i, and tweaked a few of the voltage settings to my needs...

How does this board run with RAM, dividers etc? Board gives Vdim readout in Bios?

Currently on Asus P5E got my Corsair Dominator PC10000 kit doing:

1280Mhz 5-5-5-18 @ 2.4V 24/7 stable


How long till eVGA 780I FTW edition comes out... should prove a ever better Ocer! for sure but nice touch will be no reinstall of vista etc as same board estentially!!


Ill order a 60x15 and 25mm thick fans just to be sure defo want suck vs blow right? this on NB btw!

Well, I pulled the trigger on a new Evga 780i early this morning...Here's hoping that it will outperform my Abit 680i...and by outperform I mean actually run at stock speeds without crashing!

Anyway, this will be my first Evga board. Let's hope that this experience doesn't go the same way my first Abit experience went. I don't want to think I am an Asus fanboi, but hey, so far I love that company.

Actually, I am a little worried about the 780i. The problems I was having with the 680i were those ghost problems no one can seem to figure out. I had two different boards thorugh abit (RMAd my first one) and they both refuse to work, which leads me to believe I have a hardware incompatibility or something. That, or its just the "it might work, it might not work" syndrome so plagueing the 680i boards. My hope is that the 780i, though really just a juiced up 680i, won't have the same issues with my current hardware setup that my 680i board did.

Only time will tell! Wish me luck on my new hardware adventure! (Read here as adventured in spending large quantities of money on part for "enthusiasts" which may or may not work depending)

I just installed a QX9650 and cannot get it to run properly. I have absolutely no control of the cpu fsb voltage or the vcore. No matter what I try and change them to, they stay at vcore - 1.18 and cpu fsb - 1.08 volts. It will boot to the Vista desktop for a second, then it just shuts itself off completely. I tried the QX9650 in my second rig (DFI X38) and it works just fine, the voltages can be adjusted and I booted into Vista and played a quick round of COD4, all was well.

I can change the dram voltage and the settings stick, it's just those two. I've tried the P02 and P03 bios', cleared cmos, and everything else you can think of, nothing helps. Any thoughts?

[ncsa]

Have you tried the settings here I outlined earlier? These are working with a QX9650 / Q6600 on an eVGA Board running the P03 Bios (XFX version).

Is the Vista a new install for this board and CPU or a drive change between the X38? As there are issues with Vista with 4GB> on installation, try leaving just one module in, get it updated and then add the other modules back in... had this issue here but now all working ok with the QX

Alright... just got my EVGA 780i build up and running. I have a E8400 with a thermalright ultra-120 extreme, 2X2 OCZ reaper DDR 800.

Here are my settings:

FSB:1600
Multi: 9x
memory in sync mode or 1:1
memory timings are 4-4-4-15-1T at 2.2volts. I also adjusted trc from auto to 11
NB i left in auto for now... will adjust next boot when I make some changes.
I left cpu voltage in auto or default... however I have one question to anyone that can answer. I set GTLVREF lane 0-3 to +85mv. Is this right for my cpu? What should I set this too? I read that it is unstable to leave this in auto.

This is an exisiting Vista install. It's not an OS problem, but rather an issue I am having inside the bios. No matter what I select for cpu voltage and cpu fsb voltage, they stay at 1.19 and 1.08 volts. Period. Nothing seems to allow me to make the changes stick. This is only on the QX9650. With the Q6600 in there, I can change both of those and the changes stick, no problems. It's just on the 9650. I merely stuck it in the X38 board to see if maybe there was something wrong with the actual cpu itself, something that was not allowing me to change those voltages. But, that was not the case. With it installed on the X38, I could change vcore and the changes stuck, which ruled out the new QX9650. Frankly, I am stumped on this one.

I have an MSI 780i coming in this afternoon, so I will post back if it works with it. If so, it's RMA time.

btw, I did try all of your settings. All of them took with the exception of vcore and cpu fsb voltage.

[ncsa]

Sure is a Strange one ... try a full CMOS Clear (battery out etc) and reflash with P03, maybe the Change between the CPUs is not correctly rebulding the ROMSIP area... to avoid blowing-up the Vista OS build from BSODs/restarts try a basic XP OS build on a single drive....

[shawn1998]

I reflashed back to the P02 last night, then did a full cmos clear, no change. Then, flashed back to the P03 and did the same with the same crappy results. Something sure is odd about this one...

[joe.denice]

Ok so you swapped out board right?? and you didn't reinstall your OS?? Have you tried to reinstall windows to see if that helps??

[shawn1998]

OK, let me be a little clearer.

This has nothing to do with the OS. I cannot change the voltages in the BIOS. Not being able to boot into the OS is simply a result of the voltages being too low in the BIOS. I did not swap out boards, I swapped the cpu between two different systems. My system, which has the 780i and my son's system, which has the DFI X38. I cannot change the cpu and cpu fsb voltage settings in the bios on the 780i, but I can with it installed into the X38 system.

[icon57]

^^^ rma time?
if you cant change settings in bios, weather it be p02 or p03 bios, i would do an rma...but thats just me..

[shawn1998]

I just got the MSI 780i motherboard in and installed the QX9650 on it and gee, the voltages adjust just fine and I am in Vista typing this now. Looks like a have a bum board, although I am still VERY confused as to why it would adjust those voltages with my Q6600, but not the QX9650. Very strange indeed.

Thanks for the replies.

[icon57]

yeah...looks like u did get a bum board...so did i the first time, second board is sweet...

[radical]

I installed the driver using the Pre-Install during OS install (i.e. F6 to load RAID driver) and left the disk with the files in the drive during the entire installation.

This forum has really strayed from the original intention... It's an EVGA 780i discussion thread started to talk about EVGA 780i motherboards. So if the readers/posters could search back a few pages and read my questions and comments and respond to them instead of talking about other motherboards and your other systems than that would be great... because after all... this is an EVGA 780i discussion thread started for the sole purpose of talking about EVGA 780i motherboards. Not MSI boards and X38 chipsets... no... EVGA 780i once again!

Thanks!

Here is a couple of threads from the EVGA nForce 780i Series Forum on EVGA's site. They don't specifically say what is best for your processor, but it explains exactly what those settings are. They are still trying to figure out the best setting as well. Hope this helps.

Bob.

Not sure where you got the impression we are discussing x38 MoBo's. My problem IS with a 780i MoBo. If I mentioned x38 MoBo's, it was in reference to an issue I had with two x38's I got BEFORE the 780i.

This is in no way a discussion about the x38 (or any other MoBo's).

My issue is with SATA DVD writers and the 780i board. When an application trys to use the SATA DVD writer, I will sometimes get the BSOD. The error that comes up is with nvgts.sys. This is the MoBo driver set (I assume for the drive controllers).

The other issue I now have discovered is that when I try to actually write to the SATA DVD writer (with Convertx2DVD in this case, which I think is using the Nero drivers), the application says preparing to write and a time to finish. The time to finish keeps Increasing! And when I cancel, the entire application hangs and the machine will not restart, I often have to power off.

Any one else seeing this issue? I am at the point of trying a IDE drive to see if I get the same issue.

read the first post of the evga 780i thread......we have discussed this in that thread.

[Hughyhunter]

Thanks guys.... so what do some of you all set these GTLVREF lanes to? I'm setting mine back to auto. I dont see the point. Some have said it makes it unstable but poo. I will see with prime95.

Also is cpu fsb voltage the same thing as NB? How do I adjust my NB voltages?

[Hughyhunter]

What is NVMEM test? Is this a good memory testing tool? I have EVGA 780i with 2X2 OCZ reaper DDR2 800 4-4-4-15 @2.2

Also I tried to download memtest but it says I cant because it's not compatible with 64 bit OS or something like that.

[FlyBoyGeo]

I set my GTLVREF 1 and 2 to +05mv and it seems to have helped my stability. I am currently 500x8 with 2x2gb g.skill.

Also I just reread the first page and noticed the SATA CD/DVD-ROM issue and its definately affecting my Samsung burner. I made about 10 coasters tonight, trying different SATA ports, not overclocking, fsb changes, made sure DMA enabled, tried Cheetah Burner, Nero 6 and 7, and Imgburn and nothing burnt a dvd-r for me. Somehome I was able to burn a dvd+rw???? Go figure. I do hope the come out with a BIOS fix for the SATA issue.

[radical]

read the first post of the evga 780i thread......we have discussed this in that thread.

What, that this is a 780i board discussing? Or that there are issues with SATA drives on this MoBo. Further update, verified that the IDE burner works just fine, no change to software, so I have sent a note to eVGA to see what they say about it. There shouldn't be a problem with mixing optical drives and a RAID array.
