Just got my 880M twins!

I was under the impression the flag was tucked away in the windows registry. Perhaps something similar to a ULPS issue normally associated with AMD.

 

I already tested to remove battery , gpu card, and install a new windows on new ssd, but this flag is always here, the motherboard bios reset after remove battery but not the vbios on gpu card.

 

I think this may have been done. But have you flashed back to the standard Vbios, then back to the unlocked one?

 

Seriously, try installing Linux then install the official nVidia 880M driver in the distro and run a 3D app... see if it wipes out the flag.

 

Worth a try.

 

I don't think they have 880M working on OS X yet so that would probably be a huge waste of time but there are official drivers for Linux.

yes but nothing changed

After several week of test,I'm pretty sure that problem is hardware, install a new windows or linux doesn't change anything. For me but it's just my guess, the best way to remove this flag is by reset the GPU card or something like that.
Maybe someone will find how to remove this flag.

 

So you're saying that you installed linux, installed the official nVidia driver, and ran a 3D application and the flag still exists or you aren't willing to try it because you don't think outside of the box when it comes to troubleshooting?

Even if it doesn't reset the flag, testing it in linux would be smart to see if its a hardware throttle or a software one since whatever is being applied in Windows in the current driver stream won't likely trickle down to the linux driver stream for a few generations.

 

no I didn't try with linux, just with a new install of windows 7 ultimate 64 bits, but I never really use linux and my problem is to resolve this throttle on windows.

But as I said, I'm pretty sure that problem is the same with linux because the problem not come from the OS, maybe it's not true, but in this case, how do explain that install a new windows on a new ssd doesn't change anything ?

 

*facepalm*

If its a flag being set on the card, when the linux driver initializes the card, there is a chance it will discard the flag as invalid.

It also would be beneficial to know if the card is being throttled in linux as well. Why? Because driver changes like this tend to hit linux last (if ever) because nVidia doesn't do a lot of development for linux.

You'd be amazed how many problems I've solved with linux over the years. I'm not willing to trigger the throttle on my cards to see if linux flushes it but there's no harm in your case since you are already throttled. Best case scenario, it wipes out the flag and you have working cards again and due to the nature of linux, the rest of us just need to download the driver that wipes the flag and store it somewhere and everyone can overclock without fear of the throttle man.

Probable scenario - 3D isn't throttled under linux but the flag remains in Windows. This would let us know that it is indeed something set in the card and why older drivers aren't affected. Then work can begin in finding out what changed between the new drivers and the old drivers.

Possible scenario - 3D is throttled in linux as well.

Either way, other than the time it would take to put into a linux distro install, there is no negative to testing it out.

Its extremely easy to do this btw

Set up a Linux Mint install (or Ubuntu, whichever you prefer, but Mint is easier)

Then follow this guide

http://linuxg.net/how-to-install-th...buntu-linux-mint-pinguy-os-and-elementary-os/

 

I'll format my other ssd and try to make new install of linux for test. I just need more time again :\

 

You're a trooper! I'm surprised you've not chucked your 880M out the window & stamped all over it given the amount of testing you seem to have done! Hopefully the Linux test will remove this flag that we think is being imposed somewhere, will be interesting to find out.

 

Maybe the price....

Also,I would like to say that Lee from upgradedonkey is not a good seller for me, he don't help me, don't reply to my request and apparently , he don't want make me exchange or refund this card.

Now I think use Paypal complaint, though this card was never work properly for me, it must passed in warranty

 

Gotta love PayPal. They are almost always on the buyer's side.

Wow what a POS...

I installed Mint to a USB stick and put on the nVidia drivers and it can't pass Valley without freezing :|

I removed my undervolt on the CPU and now I'm going to try it again. -_-

 

which driver version do you use for this test ? stock vbios ?

Maybe the hard throttle come to you ^^

 

331.79 driver, modded vbios, stick vbios doesn't matter to Linux (but I'm on modded vbios)

I got it to finish the second time but it froze at the same point when the test was done so I think it's the test.

I attached the image of what a single GPU did with default settings it's probably better to run heaven, I try that next.

Heaven benchmark works without an issue. I think it's just a problem with nVidia and Valley lately.



I got a freeze when I tried to turn on SLI which is par for the course with Linux really so it's single GPU only but it's very easy to do it the way I did, just need a USB stick.

EDIT:
This doesn't require installing to a hard drive, it runs right off of a USB key which saves a lot of time and effort.

Get Linux Mint 17 Cinnamon from here: http://www.linuxmint.com/edition.php?id=158 (Torrent is fast, use that if you can)

Then get Universal USB from here: http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/

Put a 8+GB thumb drive in the USB and launch USB Creator, choose Linux Mint from drop down, navigate to ISO, then choose USB stick drive letter in the drop down (if its not there, show all drives), click format, drag slider for persistent storage all the way to the right. Let it finish (will take some time) then when its done, reboot computer and boot from USB (it support UEFI and BIOS boot, no need to change any settings).

Once in Linux, use instructions here: http://linuxg.net/how-to-install-th...buntu-linux-mint-pinguy-os-and-elementary-os/

Then reboot, you will see nVidia logo flash up and go away, now get Heaven: http://www.techpowerup.com/downloads/2204/unigine-heaven-benchmark-4-0-for-linux/mirrors

Open terminal and type "cd Downloads" then type "sh Uni*" then "cd Uni*" then "./heaven" and Heaven should launch, run that and see clocks should say 954 core/2500MHz memory and you should score just slightly slower than I did. If not, you're still throttled. If you do, then reboot to Windows and see if the flag is gone.

Oh yeah, save yourself a headache and disable any overclock you might have on your CPU beforehand. Linux stresses the CPU much harder than Windows (its true SMP so just about everything is multithreaded) and you're likely to have to adjust any CPU overclock if you were pushing it in Windows like I was.

 

You should be happy, twice the score compared to my 880M SLi setup

 

That was in Linux which uses opengl instead of directx so it can't be directly compared, especially since tessellation is not available in opengl.

OpenGL leaves a lot to be desired. Many OpenGL-based games look and play pretty great with fairly wimpy GPU hardware (Wolfenstein: The New Order is an example of an amazing OpenGL game) but OpenGL game engines often lack CrossFire and SLI support.

 

OK now... time to start making some noise. If you're not happy with what you see going on with 880M, even if you don't have 880M, get on over here and let your voice be heard...

So what... am I the only one with working 880Ms right now?

Kind of seems like it. At least for now, until it decides to stop working.

In case my comments mysterious end up deleted at NVIDIA Community, here is what I posted. Feel free to copy and past the quote in their community if they delete it.

And, here's what I have stated elsewhere:

 

Such a shame...

All of this reminds me of the 7900GT... And its leaving a really bad taste in my mouth thinking of that possibility...

 

At second blush, your 880M SLI setup still is not fixed. It's better than most, but still not right. Here's what my score looks like with my CPU and 780M SLI setup running at the same clock speeds. Close, yes... but one should expect more from the latest and greatest. I would not be satisfied if I were you. This is inexcusable.

3DMark11: Compare Working 780M SLI with Broken 880M SLI

 

My CPU doesn't run 3.9GHz,its 3.6GHz with an occasion jump to 3.7GHz but my point is that I'm not in Uber throttle with the latest drivers like everyone else seems to be.

The point still stands though that I'm not happy my 5k machine is performing slower than older parts though, definitely.

Sent from my HTC One_M8 using Tapatalk

 

You're missing the point. My 780M SLI graphics score still stomps your 880M graphics score. The nice thing about 3DMark11 is that the CPU doesn't have a huge effect on the graphics score, and certainly not with a 300MHz difference. But, yeah... any Alienware or Clevo owner that spend $5K on a beast with 880M SLI has every reason to be dissatisfied. Your CPU is not running 3.9GHz because Haswell is broken. The fact that it registers at 3.9GHz before it gets put under load is just further evidence that Haswell sucks.

My Fire Strike score also beat yours with the same clock speeds. But, I think your system is the only example I have seen of a production machine with 880M that is close to working as it should. As they say, "Close, but no cigar." Newer and better needs to be newer and better... not almost as good.

Fire Strike: Compare Working 780M SLI with Broken 880M SLI

 

Yeah you got a whipping 9.7% increase over me in 3DMark 11 graphics... I'm not impressed but at least I'm not in HD 4k land. Wish I had 780s though. They run cooler either way.

And yeah, Haswell is a disaster. Every time I think I have a stable overclock it goes unstable.

I would be interested for the sake of a fair comparison to see how you bench with drivers that were released a year ago.

 

Did the 780ms have driver issues at release too?

 

From what I've heard, yes, but nothing like this intentional crippling.

If it isn't intentional then nVidia has a lot of bad cards going out that are glitching hard.

Sent from my HTC One_M8 using Tapatalk

 

When they work, they work well...

 

Driver optimization issues, yes... definitely. That is actually fairly common whenever a new GPU is released by NVIDIA or AMD. But, severe functionality issues like we are seeing now with GTX 880M, it did not have. It took a bit of time before GTX 780M soundly outperformed GTX 680M by a wide margin, but all of this nonsense we see now is something new. I certainly hope it is a firmware and/or driver fix and not a huge batch of bad GPUs. I doubt that it is, but that is definitely possible. It's hard to explain why a few rare examples like Ethrem's GPUs and those that SVL7 and Johnksss tested work so much better than others. But, we should not say too much and jinx Brother Ethrem. If his setup gets hit by the flag, bug, glitch, or whatever it is, it's going to be very frustrating to deal with.

 

Maybe I'm fortunate that I have Windows 8.1... driver hasn't crashed once, the system freezes.

I propped my laptop up using two Walgreens bottle caps... damn the temperature difference is insane, these machines should come with fold out legs

I think I need to repaste though... my master card is running cooler than my secondary card unless its being reported inverted, which is possible.

Currently @ 105 core, mem seems to max at 475MHz, it freezes at 480.

 

Well, your GPUs are definitely working better than most 880M. But, it's still not all it should be. With a lower core overclock my 780M SLI score is basically the same as your Fire Strike score above. And, I slowed down the CPU to 3.7GHz this time just for good measure. Windows 8.1 does handle TDR errors a bit differently than Windows 7, so it may be helping avoid whatever triggers the malfunction, but some other 880M owners running Windows 8.1 are having major problems. I think you have just lucked out on not triggering the problem so far. *knocks on wood*



Question: Why does your signature say "This system rocks!" if you are having temperature control problems and your 4940MX doesn't perform up to expectations? Not trying to be mean or insulting, so please don't take it that way. Just doesn't seem that statement fits some of the comments. Does it really "rock" or have you not taken time to update your signature?

 

Haven't taken the time to change my signature. It rocked when I got it but as I've used it, I'm becoming less and less impressed. The thing that really brought it into focus for me was when I built my desktop. My 4770k is terrible (4.4GHz at 1.32v) but the 4770k at stock outperforms my overclocked 4940MX because it requires more power than the system gives it stock to hit it's stated boost clocks and when you give it that power the temps quickly hit 89 and 90C which is unacceptable to me.

Add in the slaying my 880Ms get by my 780 Ti and yeah...

Well I appear to have hit a wall. 105 core is the most it will do at 1.075, even turned off turbo for the CPU to see if it was a power limitation but it froze again at 115 with the CPU pulling 900mv.

I'm going to keep pushing it but as you said, even overclocked it isn't performing how it should which is likely a driver issue in my case but there really doesn't seem to be a lot of headroom for an overclock either.

To be fair though, out of the box the system performs well, it is just when you want to push it that it disappoints. I should have gotten the P570WM with the 780M, especially now that I have my machine propped up which makes it taller than the 570.

So it just failed 115 at 1.082, its not looking good

Okay so the max overclock I can get is +95 on the core up through 1.1v

I won't push them any further because my slave (yes, its my slave, I set single GPU and ran the test but because of the voltage bump from being the primary card, I already knew it was the slave) is running 8C hotter under load than the master. I'm going to have to investigate it and see if I messed up the paste job or what. It really sucks that I had that test BIOS brick my cards which meant I had to repaste, something I have no experience with, because my temps out of the box were only 1-2C difference between the cards with the master being hotter like it should be. I haven't flashed back to the stock vbios to see how much of a difference the constant boost is making but I'd imagine its no more than 2-4C.

Anyway, +95 core, +475 mem @ 1.068v for me. 115 is not possible all the way up to 1.1v, it freezes as soon as it finishes the second part of Firestrike which means it likely would be stable with more juice but that's a LOT of juice for 20MHz.

EDIT: Even that overclock isn't stable, I tried it after turning off turbo boost to try and set up a possible 1:1 situation for you Mr. Fox and it froze right into the benchmark. These cards are garbage.

 

Well, they might get fixed so don't give up yet. It's very frustrating to not get what you paid for at the point of delivery, but there is still hope that NVIDIA will either release a vBIOS update or fix their drivers, or both. At minimum, 880M should perform exactly as good or better than 780M and offer the advantage of twice as much vRAM.

 

Its the memory. It doesn't like over 450. I'm at 120 core at 1.075 right now and still testing.

Sent from my HTC One_M8 using Tapatalk

 

I've run my single 880m at 120+ core clock, 800+ memory, 50+ mv.
I've hit a score of around 9.3K in 3D mark 11. This card can over clock like a best when it actually wants to.
It's just getting the modified vbios to function 100% of the time, that's the problem.

 

Your memory is better than mine. It will not cooperate over 450. It wouldn't surprise me if one of the cards will go higher but not both.

Highest core I've gotten is 140 @ 1.075, 150 seems like a stretch and just failed at 1.087. Pushing it to 1.1v and going to see if I can't squeeze 160.

You have an alienware which means you likely have Hynix memory. Maybe this batch of Samsung sucks. :/

You're far too optimistic brother Fox, nVidia would've done so a long time ago if they really intended to do so. I am of the opinion that everything that we're seeing is a deliberate and calculated move on nVidia's part rather than them being sloppy or incompetent.

 

Well that was lovely... Power brick blew. Its completely dead.

What killed it?

My CPU running at -80mV with the 880Ms @ 1.1v

Good thing I ordered two. Now I get to replace it. It shouldn't have died from that... There's no way an undervolted CPU and slightly overvolted video cards should have fried it. The system appears to be okay, should I be worried?

I wonder if the power brick was faulty all along and if that hasn't been the cause of my stability issues I've had with running the system on stock clocks...

Oh yeah, this is what I managed. I left the system @ 3.1GHz with no turbo boost so that you would be able to scale to my results better Mr. Fox. Keep in mind that everything in my machine is slower than yours, including the RAM.

 

That shouldn't of killed your PSU, end of. I would say that your PSU has either shorted or it was already on the way out. Although, a 240 watt PSU is required for a single 880m. Spock speeds almost max out the PSU. Trust me on this, you need at least a 330watt PSU for a single
880m if you plan on OC.

 

Yeah it was the stock 330W power supply that Clevo sends with the machine. I'm using the second one now.

If it was a faulty power supply from the start, that would explain the stability issues I've had with the machine off and on since the beginning.

Its unlikely it was a short... the power supply wasn't moved at all. I was benchmarking and the system froze but the display dimmed too... I powered it back on and it was still dim and that's when I noticed the battery icon so I unplugged the plug and plugged it back in and it didn't go away, looked down at the PSU and the green light was dead.

I can't call anyone until Monday either because XOTIC's support is closed on weekends. Its a damn good thing I got a second PSU but I'm irritated more than I already was that they didn't include that adapter although from what you're saying, it probably would have died even with the adapter... ugh. Figures that I'm literally 1 day out of my 30 days and I have a dead PSU.

 

You may have tripped the internal breaker. If you unplug it for a bit and plug it back in does it come on again, or just still totally dead? Before I built my dual 330W mod this used to be a frequent thing with a single 330W adapter. You need two anyway, along with Clevo's junction box. Since 680M SLI was released one 330W adapter has not been enough power and if that brick was already a little bit weak it probably gave up the ghost when you were benching. I have had about 4 crap out on me in about 3 years and all replaced under warranty. They get a hard workout with machines like these.

It is possible it was causing some instability, but in my experience they usually work right until they stop working, so I doubt it. Those I have had that failed did not cause any stability problems, but it is still within the realm of possibilities.

 

So irritated... I'll call them about it but I'm going to demand they give me the converter box. Who buys this kind of machine and doesn't overclock?

Sent from my HTC One_M8 using Tapatalk

 

You are correct Mr. Fox, I plugged it back in and it worked.

I'm going to see if I can get XOTIC to ship me the converter box. Its like 70 bucks online and I don't feel I should have to pay for it when the system is pushed to its limits, especially with how much I've already invested...

I'm starting to regret not getting an M18xR2 from Dell's outlet and upgrading it myself.

 

In your situation I would politely ask XoticPC if they would consider a "downgrade" to 780M for you. I'm sure they can get a hold of these cards easily, and if they're fair they shouldn't really charge you anything since it's technically a downgrade.
