It's nice that they have fixed it, but this is not the first data-corruption-issue with nvidia-chipsets, they will have to show a good track-record for some years before I trust them again.

Frankly, I've had incredible amounts of trouble with my eVGA 780i... lots of bugs, quirks, other problems. The 780i's notorious video corruption problem was FINALLY fixed, but I still have other problems.

I'm really starting to doubt the QC work there. I know new tech is never 100% flawless, but some of the flaws that they have have been rather high profile.

Bought and EVGA 790i Board, had enumerable problems with just keeping the system running. I guess it never got it running long enough ever corrupt a disk.

I use the PC to Fold (http://folding.stanford.edu/), but the moment the CPU went to 100% usage the CPU Vcore dropped so low the machine would just hang.

Tried upping the Voltage on the CPU the Memory even the FSB and NB but to no avail I just couldn't get the machine to run for more than an hour, without it hanging

Finally gave up on all the crap I was doing and have now bought myself an ASUS P5e3 Premium (X48) and it runs 100% 24/7 without one issue at all.

I'm RAM'ing the board back to them but to be frank I'm not holding my breath on the next board working any better.

Nvidia needs to climb back into it's little hole making good GPUs and leave the other more complicated stuff to people who know what they're doing I.E., Intel. The 680i, 780i and now the 790i, all started out with the same problems, data corruption and the VDrop and VDroop problems, if they can't get it right this far in the game.. I wouldn't be buying any shares in them.

And for God's sake release SLI licensing to Intel, stupid asses, if they think they're being smart by not doing so, I'd say they're cutting off they're noses to spite their faces.

I for one would rather use AMD's Crossfire tech now since I'm forced to use a chipset that works.

I am afraid i have to agree, quite an experienced overclocker, but never really got a chance with the 680i. I was unfortunate enough to get the double whammy 680i and the ASUS version. When your board dont work, you want a warranty... or at least somebody who responds.. mines still in its box, its been in it since November 3rd 2007 when id exhausted 2 months of trying to work at stock speeds. They never got back to me, ive lost all will to continue chasing and put it down to a bad investment. PS if anybody wants a striker extreme as frisbee or stress toy, let me know.

It had the dreaded CPU Init problem, it also destroyed 2 sticks of DDR2-1066 which was quite expensive when it was purchased, fortunately Corsair have excellent warranty and no quibble replaced but commented about the 680 being a ram killer... probably from their warranty costs hitting the roof. Also somebody else commented, forget 4gb of ram or more.. The board wiped out my Data 4 times before i put it back in the box and decided it was a good idea to stick with tried and tested Intel boards.

Ive been running an X38 since November and now have a Rampage Formula X48 running stably with a tidy overlclock. Im sticking with this until nehalem upgrade, this is plug and play for initial setup at stock speeds and completely stable overclocker if you want to thrash it.

I wont be believing the SLI marketing machine until its on an intel board... Do and your in for a whole world of trouble..I rest my case.

Nvidia claiming to work with Gary and the community is nothing new. You can look for my post to Gary's last article on nvidia corruption issues in the link below.

http://www.anandtech.com/mb/showdoc.aspx?i=3279&p=4&cp=5#comments

Gary cared about the issue far more than nvidia did. You can be sure that nvidia will try to make it look like they are working with the community, but their ultimate solution will be to tell you to buy a new board with their latest chipset.

Reply

Well it's a mark of credit to Gary and the Anandtech team that they are going the extra mile to try and help the community test for more bugs. That's the community coming together in a good way to try and get to the root of the problem. At least if it they can determine what boards need to be RMA'd, they'll help frustrated folks find some resolution. (hopefully) So kudos on a good effort there.

As for Nvidia's chipsets, one has to ask how many times you want to be fooled. As far back as I can recall there have been issues. Drive corruption is hardly new to this chipset. It's just frustrating that it went out the door with that problem, after years of experience telling them they should have been more careful. But there just have been issues with every single generation. How long do we, the community, even bother to try them just to hope they finally got it right?

There's a reason they are hesitating to cross license Nehalem for SLI. They know, perfectly well, that their chipset business is either dead or it's going to have to take a HUGE step up in quality to stay in the game. And after years of trying, I have a guess that they know perfectly well they can't make a good chipset, so they are doing anything they can to protect it, preying on the ignorant customer for as long as they can. There is no way they could survive at the current quality levels. And frankly, after so many years of trying and failing, their chipset business should be long dead.

Is it possible this problem could also effect the 9800GX2?

In stressing my new system, with this 790i EVGA board (It is an Alienware system though) if I just leave a very complicated scene on display for a few hours I start getting texture flickering and other issues that can eventually cause a lockup. When playing I have only seen it one time. As long as I am "moving" I don't see the issue. Restarting the game fixes the issue immediately

(A good place to see this is the first beach you get to with enemies, a little shack and a pier. Stand at the pier and you get a lot of rendered horizon, crabs moving all over, water, clouds, jets, etc. Just leave it there and the problem will occur after a "long" time (sometimes an hour or so, sometimes more) Heat is under 70C on both GPUs so it isn't heat (as measured by hwmonitor, max never gets over 70C while doing this)

I am using GeForce Release 175 WHQL drivers. I have a "beta bios" from alienware that has a filename EVGA_790I_P04.zip

The Nvidia boards are the most expensive out, there're some cheap server board that cost less. Every new chipset have corruption issue, every. How can you trust them still ? Corrupt HDs is way a too big issue.. you lost your data, your documents, your images for what ?... only to run SLI ? Go to hell...
I wish that Intel hardball to Nvidia heavy about SLI, no SLI no Nehalem license at all, so you chipset business will just die or move to second rate market AMD where you can simply forget about sell your board to $350-400 board with sub par CPUs...


Reply

While your english sucks, I think you make a very good point. I don't trust nvidia for chipsets anymore either. Won't look to AMD/Nvidia ever again unless Intel screws up big time.

Reply

As the 780i chipset was basically a minor update to the old 680i, I actually thought that Nvidia would have fixed its issues by now. How wrong was I? Well I have a two 8800GTXs and 4 raptors in a machine which I CAN NOT trust. Even at stock speeds the chipset is unstable!

To make matters worst I bought a Asus Striker Formula... So BIOS fixes and support are just wishful thinking.

Lessons learned:
1) SLI is just not worth the hassle of Nvidia chipsets. (ATI all the way from now on)
2) Asus make great boards, but if it's a bad one don't expect help.
3) Buying a premium board does not mean premium service or quality.
4) Read the forums more, I could have saved myself this trouble.

I recently got an EVGA 680i board to run two 8800GTS 512s in SLI. I guess all the kinks in the 680i were worked out cause its run nearly flawlessy. I got one blue screen yesterday (Vista x64 Business), didn't see what from but looking at the system logs, it might have been something to do with a background task that always runs from Visual Studio 2005. Was playing Age of Conan.

I haven't overclocked at all yet. Really haven't needed to.

After reading these disturbing comments about data corruption I'm glad I stuck with the x38 board. It was a very difficult decision. I read and read user comments about motherboards before my decision. But there was one comment about data corruption that reminded me of a problem I had with a previous motherboard made by ABIT with a VIA chipset. Every new BIOS revision they came out with to fix the corruption problem slowed the motherboard down. After several bios updates it still corrupted and was slow. I questioned MY ability to build computers but built another one anyway. It turned out great. I learned quite a bit from the experience. Research the parts, be conservative, and don't believe professional reviews.

It seems that mediashield isn't working on my nForce 4 AMD SLI board for some reason, it's like it's not even there. The latest drivers seem to be buggy. Me thinks someone at NV is messing with the software, who either shouldn't be, or shouldn't be. It's like they're sabotaging it... That same board had the raid array drop out, twice after seeming to work fine for awhile. Everyone seems to be reporting problems lately, is something amiss?

Reply

I have owned my 790i since it frist came out and have not had any problems with this board at all. Maybe i am one of the lucky ones that got a good board. i am running a QX9650 @4Ghz 6Gbs of OCZ 1600Mhz and two 9800GX2s which will be changed to two GTX280s some time next week. There will always be problems wirh new tech, its just not nVidia that this happens to, if you belive that your lieing to yourself.

The article is talking about problems while overclocking, or put another way, running outside listed specifications.

There's nothing wrong with trying to push your systems, but don't start complaining when something bad happens because you are running your system in a way it wasn't intended to.

Reply

your darn right they are complaining, these folks are paying a premium for boards clearly advertised as top of the line overclocking and feature laden. If they weren't interested in overclocking they would buy any old cheap board and be done with it. They expect to get what they pay for.

Reply

There will always be someone unhappy that their new rig won't overclock to 8GHz, but those people are pretty easy to spot. We're not talking about them...

I bought my over priced SF2 because it was advertised to overclock very well, which I assumed was by virtue of high quality design and components. I was wrong.

My 780i isn't stable at stock speeds. I lost one of my Raptor drives last night whilst running at stock speeds. Random HD failure or victim of MB corruption, don't know. I know I don't trust this chipset anymore.


Reply

If things are failing at stock speeds, then there's definitely a problem (and I've never owned anything with an nVidia chipset, so I can't really comment on their product).

That said, even if nVidia says that they support overclocking of every component on the board and that your chances of a successful OC are good, doesn't mean you have a guarantee for anything other than the specification it was listed at.

I've never seen a product with a stated guaranteed OC.

This is going back, but my Celeron 300A couldn't hit 450 no matter how much voltage I gave it*, in a couple of motherboards. 384 was the highest it would go. OCing is just luck of the draw, even if you paid a premium for it.

*I did hit 450 if I stuck the whole computer inside of my deep freezer :p

Reply

"I've never seen a product with a stated guaranteed OC."

You keep missing the point homie. Other chipsets have had no problems with overclocking, even when "Extreme" versions cater to the HARD CORE overclocker market. Again, as someone else stated, we are not talking about someone trying to hit five freaking GHz. This is basic stuff, and CLEARLY nVidia, of which I am a strict GPU fanboi of, fails to measure up in the $300+ "Extreme" overclocking motherboard market.

I'm glad like hell I held off on going with a 790i. I'm going to get an x48 and just suck up going with a single 9800 GX2. Good enough for me for zero headaches.

I owned for a few weeks an NVIDIA 570 SLI based Foxconn motherboard (N570SM2AA-8EKRS2H) which wouldn't work with my Western Digital Caviar WD5000AAKS if the NCQ (native command queue) feature were enabled in the driver configuration for the device, even when the system wasn't overclocked. System would lock up often at random times and once WD's own diagnostics utility simply corrupted most of the data on the drive. With NCQ turned off the drive would work perfectly. I presented the problem to all three parties (Foxconn, NVIDIA and WD), and none of them was able to present a solution and really didn't seem to care.

My Problem wasn't even over clocking, all I wanted was rig that ran 24/7 with the CPU at 100% Load. the Nvidia 790i couldn't even give me that for more than an hour, before the whole thing just hung.

I changed RAM, SMPS, HDDs, CPU (I use a Q9550), every(bloody)thing I could think off but it just wouldn't run at 100% load.

Guess maybe it's made for those guys who run with with exotic cooling, for 10 secs just so they can post they're cpu-z scores, to make other people go ooooooowww. BTW this rig is water-cooled so it never went past 34C even at 100%.

But sustained loading at 100%, even without an over clock just doesn't work on this Chipset.

Flaky fluff would be my opinion of this chipset.


Reply

It sounds like maybe your chipset is getting too hot, this can lead to lock ups and crashes. You say you're water cooling, so you assume your temps are fine, but if you don't have good airflow through your case, it's likely your bridges are getting toasty. I've had to replace decent chipset coolers on an nForce 410/430, 6150 onboard before and then they were rock stable. Try blowing fans on the mobo and out through the case and see if your problem persists.

Timeline:

Jan 2008 - 780i Boards Launched.
29th May - Nvidia (finally) admits video corruption issue.
3rd June - EVGA release BIOS update P05 containing fix.

Asus??? Where are you??? Let me guess, an upgrade to the equally troubled 790i is the recommended fix. I'd would ask on your 'support' forum for an ETA, but I've never seen anyone from Asus on those...

Reply

What part of the meaning of 'overclocking' are you all having troubles with?

There explicitly isn't any guarantee about reliability when you manually exceed the manfuacturers specified clock rates or voltages. Get over it. How is it you guys think that this is the manufacturer's responsibility?

If y'all keep whining about low overclocking limits, all that will happen is that manufacturers will respond by making the default system clock lower, so that overclockers can successfully wind the clock up by more. All you'll be doing is reaching the same speed that the manufacturer would have sold it at anyway.

Please take the time to read / research before posting. If you check the forums you'll see plenty of people having issues at STOCK speeds.

I'm not going to defend overclocking practices. If you push a part too far it will exhibit instability, I think you can safely assume that everyone knows this.

In my opinion the 680i/780i chipsets are pushed too hard even at stock speeds, heat and component failure issues are well documented. This is why some people have perfectly working systems, whilst others suffer all manner of problems.

I feel I should be able to complain about this. Nothing will happen though.

I have an Evga Nvidia 680i that I bought and was relatively mature with the P29 BIOS. However it still had a ton of compatibility issues. This board is like some stuck up rich girl with a terrible attitude. Outrageous expectations for me to buy her top of the line hardware. If you don't you're gonna hear her bitch and moan. Anything you try to do for yourself she's gonna drag her feet. Once everything does click it's a wonderful thing. However it's just not worth the effort to try make it work.

These boards are so picky when it comes to RAM. Read Nvidia's RAM compatibility list? Me too but you can throw it out the window because I think they just added their partners because they're friends. Well, simply put it's the you scratch my back I'll scratch yours kind of mentality that got them in trouble with the TWIMTBP. Forget overclocking if you have 4 gigs of RAM, as you'll be lucky just to get it to run with 4.

Nvidia software RAID? Really? Alright since this is my first Nvidia board I'll try it. Two 500GB WD HDD corrupted after one week of use. It was fast while it worked. However all my data is gone and the Hotfix issued by MS and Nvidia didn't do anything.

The reference Nvidia BIOS sucks too. Right now I'm using an XFX P30 in my Evga board because Evga is afraid to deviate from the norm. The XFX BIOS is so much more stable and the FSB holes at around 3.8Ghz are gone. My maximum OC with the 680i and a Q6600 is 4.1 Ghz.
http://valid.x86-secret.com/show_oc.php?id=321578

I love this board now but without the right or rather compatible hardware Evga will just tell you to RMA the board. They told me to RMA it on three separate occasions and all three times it came down to compatibility issues that I had to figure out for myself. This will be the first and last motherboard I buy from them.
