Pidge from Nvidia has asked that user experiencing problems with the 880m list them here..

I thought about that but I tried raising the voltage to 1.025v with no improvement in stability and of course an introduction of 94C.

I also had issues when I rebooted the machine where I would see the tattle letting you know it has a modded vbios but it wouldn't POST and would just reboot until I pulled out the A/C adapter then it shut off, I turned it on unplugged and then it would POST and boot just fine. It also worked fine if I shut the computer down and turned it back on but it would not work if I rebooted the machine instead. Needless to say I won't be using the mod anymore.

That's strange. svl7 personally owns an AW 17 (i7-4910MQ + 880M) so he should be intimately familiar with the vBIOS. I suggest asking him about it at T|I. I'm running an sBIOS and vBIOS, both modded by him without ever having owned/used a Y500, and haven't run into any problems except the occasional "attempted to read or write protected memory" error with Nvidia Inspector which doesn't affect anything.

 

It's possible that the vbios isn't stable on Clevo machines OR it could be that it's not stable on SLI machines. I'm leaning towards the second option since deadsmiley and a few others with single cards don't have issues.

Weird things do happen. The first vbios I was sent to test bricked my cards and required me to stick one in my M17xR1 and reflash it stock because of a glitch that apparently didn't affect Optimus users but caused non-Optimus machines to not POST.

I've posted on TI, I think svl7 is away or something as he hasn't updated the thread in awhile. Last I heard he was going on a long vacation.

Yeah he took a sabbatical I think. Went skiing or something.

 

That was what he told me, I just didn't know if it was public knowledge lol.

WELL I find this complacentness that im starting to see to be bull... Nvidia should be held accountable for this and issue a fix for these cards before they drop any new ones or issue us the new top dogs when they come out...
so what if it makes them hotter.. mine run no more than 75-79c. this is highly unacceptable and they should say some thing.. also where had pidge been? he tells us they found the issue and then just disappears? not one word of an update?
Nvidia hiding posts? this is very frustrating..

although i'm not all that happy with alienware at the moment.. not only is the new 18 plagued with issues of its own down to the cpu,fans tables and what not... the dang gpus don't operate correctly..

 

They are operating the same way that reviewers saw. It makes me wonder if the 780M doesn't core throttle as well on stock vbios and nobody monitors it. Because my 780 Ti has varying degrees of throttle with its stock vbios also. It seems to be a boost thing so any card with boost should have some degree of it on a stock vbios.

FWIW I game with the OSD on and I've never seen my 780M throttle with the stock vBIOS.

 

Then nVidia did it on purpose with the 880M by setting the power threshold very low. That's what causes it on my 780 Ti, raising it to 106 makes it hardly ever happen.

They probably capped the TDP to help with the temps, because 125W of heat is no joke.

 

Its not but they have it way too tight right now. I want something inbetween stock and the mod.

Has anyone thought about creating a petition about this?I am planning to do so as it will be easier to share this i am also suffering from throttling and overheating issues on my 880m since i purchased my alienware 17 which was replaced twice due to this and still the same problem.

 

Well that blows. Seems like you're stuck between a rock and a hard place. Stock won't Boost due to hitting the 117W wall set in the vBIOS. Modded vBIOS unlocks power limit and runs full clocks but overheats and throttles. Guess the only thing you can do at this point is underclock and undervolt or lower Power Target (both accomplish the same thing) to a sustainable performance level where the card won't overheat. Or mod the hell out of your machine to improve cooling so it can maintain full clocks on modded vBIOS without overheating.

The 880M just seems like a broken card stretched beyond its limit for a notebook form factor.

 

Unfortunately since the modded vbios isn't stable on my machine, I'm stuck. I can't down clock enough to make a big difference and down clocking just makes the throttle worse when it's imposed. I even tried undervolting the cards to 1v and that choked them. The stock vbios doesn't allow for anything.

Sent from my HTC One_M8 using Tapatalk

 

You can't underclock and undervolt your 880M far enough to match a stock 780M? Well that stinks. You should really see about getting the modded vBIOS working on your machine. It seems like your only hope right now.

I'll bet you anything, if Nvidia ever gets around to "fixing" this problem in the vBIOS, all they'll do is raise or unlock the power limit so the cards fully Boost to 993 MHz and overheat. Maybe they'll raise the temp limit from 93C to 100C while they're at it. Reduced lifespan, but you get the performance you paid for, right?

You can't fix what is inherently broken. The 880M wasn't designed to be able to be cooled properly in notebooks.

 

Its boost that causes the problem but I think you just gave me an idea... EVGA to kill boost and then change the core and voltage with inspector. It may work. The trade off though would be having the cards locked to 3D frequencies all the time which makes the fans spin ;/

I logged the stock voltage... 928MHz @ 0.968 would be acceptable if it doesn't throttle.

So EVGA K-Boost locks it in the P0 Boost state all the time? That's really stupid, but I guess if it solves your problem and you don't mind the extra fan noise...

Does setting Power Management Mode to "Prefer Maximum Performance" in Nvidia Control Panel help at all?

See, this is why I hate these boost algorithms all the new GPU's are using. They get in the way and tend to obfuscate things and cause more problems. A GPU should have one set clock speed and voltage and not vary wildly based on fluctuations in power and temperature.

 

Boost makes sense for laptops but it is being abused for sure.

And yeah that's what K-Boost does. I already tried it to see if it stopped the throttling and it didn't but I wonder if the situation would change if I combine K-boost with an underclock and undervolt. I'm running memtest right now but I'll experiment after that's done.

Sent from my HTC One_M8 using Tapatalk

 

No Boost makes absolutely zero sense in laptops because stock vBIOSes are all locked down and don't allow you to adjust power and temperature targets in software, which means you have no control over Boost and are at the mercy of whatever your manufacturer decides to set in the vBIOS, as you are finding out the hard way.

 

Its being abused in this situation but I can see the use for it. Not all laptops that get high powered video cards are actually able to sufficiently cool them. I mean mine isn't sufficient to cool these cards at full boost, 90s happen in an hour.

It should be user programmable though. Set the severe throttle to 94C and let the user decide what the limits should be outside of that.

Sent from my HTC One_M8 using Tapatalk

 

Exactly. Give notebook GPU's the same level of control as desktop cards, meaning full clock, voltage, power, and temperature adjustments, and we wouldn't even be having this discussion.

 

Desktop cards don't get full control either. You have to have a modded vbios as well. Power target is only adjustable by 6% on my 780 Ti which is quite small. It's not sufficient for 24/7 boost.

Ah, very interesting, you've had the "attempted to read or write protected memory" error too with NVidia Inspector! I had wondered what was causing that - it's very rare & doesn't cause any issues for me, but interesting that you think/know it's related to the modified vBIOS (I'm also running his modded vBIOS, very happily).

 

Yeah you're right. Nvidia went insane with Kepler. ****ing Green Light Program. What were they thinking, volt-locking all their high-end cards?!?

Even your 780 Ti only goes up to 106% Power Target? Now that is just stupid. Even some of the lower-end cards go up to 130%.

*hugs non-nerfed 7950*

 

My 780 Ti runs hot anyway since the fans on my H100i tick me off, I keep them on silent which means my ACX cooler puts out heat and it doesn't get moved unless the game uses a lot of CPU and kicks the fans up. The noise the fan on the Ti makes is even more obnoxious, it whistles, I've never heard anything like it, so I keep that fan low too.

But yeah, overclocking is pretty limited on stock vbios which is why they have the kingpin classified with dual vbios. You keep one stock and flash a mod to the other and as long as one of them is an EVGA vbios, you don't lose your warranty.

It's either due to the modded vBIOS or a bug with Inspector--I can't be sure. I have Inspector set to automatically apply my clock and voltage settings at boot and wake from sleep/hibernate with a couple of Task Scheduler tasks and I occasionally get this pop-up. Not a big deal though.

 

(Yep, I've got mine on a Task Scheduler too (undervolt & stock clocks on startup), but the errors I've seen have always been when I've manually started an NVidia Inspector Overclock from the desktop - but only about once every 2 weeks or so, and that's with applying overclocks a couple of times per day)

 

EVGA's on the bottom of my list of GPU's to consider, especially after their recent fiasco with Precision. Never been a big fan of their cheap plasticky ACX Cooler either and it's not exactly known for its exceptional performance or low noise, but you bought it for EVGA's famous warranty, amirite?

 

I've gotten the error when both auto and manual overclocks are applied, and it seems to come and go, i.e. I haven't found a set pattern yet. One week I'll get it every day, next week I won't get it at all. It's a minor issue and I've given up/gotten over trying to fix it. I'm gonna reformat with W7 Pro soon since my W8 Pro install just bricked itself, so I'll see if that does anything, but I doubt it will.

 

Their ACX cooler is one of the best on the market, I don't know where you heard otherwise. It just needs proper airflow which it would have if my H100i didn't have such noisy fans.

I'm a huge fan of EVGA, I had one of nVidias other terrible cards, the 7900GT. it failed and EVGA cross shipped me a 7950GT. I had an EVGA 8800 GTS for years and didn't have any issues with it either.

When I kick the fans on the H100i up, the card doesn't pass 79C @ 1156 - http://www.3dmark.com/fs/2296599

The fan is likely defective but I haven't felt like replacing it since the card never gets hot enough to need to kick it past 40%, a reference card is much louder, its just the pitch of the noise that annoys me.

I read the stock H100i fans are pretty bad, should consider swapping them out for some Noctua NF-F12. Acoustics seemed pretty reasonable from a Youtube video.

 

The only reason I haven't swapped out the fans is because I would have to pull out the entire motherboard to replace them since I did a push configuration and installing the H100i in the first place in my NZXT Phantom 410 was an extreme exercise in frustration...

ASUS, MSI, and Gigabyte are generally considered the top 3 in aftermarket GPU coolers, with some exceptions such as the Sapphire Tri-X. EVGA is usually middle-of-the-road. Not saying that it's bad in any way. Of course it's gonna be better than a reference cooler, except if you're doing SLI, where you'll want a blower instead of an open air design. But most people buy EVGA for its exceptional warranty.

I have the superclocked acx card.

The MSI Gaming beats it but I would *never* buy anything MSI after having two of their motherboards. Worst. Support. Ever.

Of course, if you want the best high-end mobos on the market, ASUS all the way. But ASUS, Gigabyte, and MSI all make solid GPU's.

 

I have an ASUS Maximus VI Formula board and I love it. My first ASUS board. Last was an Intel Bad Axe 2 and before that I had Biostar's awesome overclocker with my Athlon 64.

Highly doubt I'll ever have another brand for motherboards. I looked at the DirectCU II 780 Ti and was interested but I chose to stick with EVGA because of the warranty ultimately. 1156 at stock voltage isn't bad for a reference board.

Oh? Could you elaborate? I just can't picture why you'd have to pull out the entire mobo to replace the radiator fans.

 

Can't get access to the screws :/

Sent from my HTC One_M8 using Tapatalk

 

Well of course, I wasn't thinking straight. Wonder if this is unique to the Phantom 410 or just an unfortunate mobo + case + radiator placement combination.

 

I'm not sure but this case is monstrous enough, anything bigger wouldn't work where I have it because I need to have a good bit of room for it to vent out. I should have installed it in a pull configuration instead of push but honestly, I don't think I trust the screws to hold the radiator up so I'd rather have it like this (there is a metal piece that sits inbetween them right now so gravity can pull all it wants the radiator ain't moving) even if it's a pain later.

If the case was like my old Antec I could just pull the tray out of the back and be done in a few minutes. I should have checked for that feature before buying a case but this was my first time with liquid cooling so I didn't think it through.

Sent from my HTC One_M8 using Tapatalk

 

Hmm well I guess I'd better go read some more, or remind myself to dump the stock fans and install the NF-A14 PWM fans on the H110 radiator right off the bat. If this desktop gets built it will also be my first time with liquid cooling, nevermind the fact that it'll be the first desktop I'll be building since 2004 lol. Got a lotta homework to do...

 

Lol it was my first in quite awhile as well. I think I built my Q6600 Bad Axe 2 in 2007 and the only change I made to it over the years (still have it) was changed the video card from 8800 GTS to Radeon 5830 and added a hard drive or two.

This new build was frustrating. Maybe I just don't have the patience for it anymore.

Eh, since I burned out my 5870, which was completely non-reference (both cooler and PCB), I've made it a point of emphasis when buying AMD GPU's to only consider cards with a reference board and aftermarket cooler because the reference boards are better and AMD stock coolers are, frankly, utter crap. Nvidia is the opposite--non-reference PCB's usually have higher quality components, which is good even if you're not doing extreme overclocking, and their metal stock blowers are both effective and incredibly sexy.

 

I haven't had issues with an nVidia reference except the 7900GT but yeah, considering how much I was already spending on that 780 Ti, I should have just bumped it up to a classy.

I fixed it lol. It was a 5830. It gets confusing keeping track of the numbers when you've had so many cards over the years. 5830, 9800 XT, X800 GTO, 7900GT, 7950GT, 8800 GTS, Voodoo Banshee... Only the last one isn't easy to mix up with the rest lol

Oh yeah I fully expect this to take about a month to build with actual build time spread over several weekends. Weekdays I'm just too tired and demotivated when I get off work, so all I want to do when I get home is blast some music and watch movies or waste time on NBR and Youtube. Plus this way I have something to do on the weekends. I fully intend to take my sweet time with this build, especially since so much has changed since 2004 I may as well know nothing about building a desktop. (well the basic principles are the same I guess, but lights and case fans were a rarity back in 2004, AIO coolers didn't exist, and the overall build complexity was just an order of magnitude lower)

 

That would be X800 XT or XT PE, not GTX. LOL. ATi/AMD has never used the GTX designation, that's been Nvidia's thing. :laugh:

 

It only took me 2 1/2 hours to build my machine it was just irritating. I still haven't fixed the bracket on the H100i. I didn't realize that it has notches that line up with the socket so I installed it sideways which put uneven pressure on the CPU. One core will be 68 while the hottest is 75 lol. Oops.

That was my auto correct. It was an X800 GTO, again I fixed it immediately but you still saw it XD

ROFL X800 GTO. So there was that card too. Video cards and their confusing naming schemes. Some things never change.

 

Card was nice. Flashed to an X850 and got an extra four pipes for free lol.
