My Nvidia GTX 880M Test Run Review

Mine won't drop even after I flashed my stock vbios back to my 17's 880m.

 

I had to uninstall and reinstall the driver last time.

also make sure you don't have the clocks locked using evga precision

 

I may give that a try tomorrow.

I don't have my clocks locked.

Update: It appears that my stock vbios is acting normal now. My 880m isn't running at all when in 2d applications. My Intel HD 4600 takes over according to HWIFNO.

 

Hey guys!!

My first post here. First of all, i want to say thank you to everyone involved in this thread. I recently ordered a np 9570 with 880m sli and a 4820k, which i plan on overclocking.

Manuel finally got back to you folks on the vbios issue, and thats exactly what they think it is, according to the link below, they are finally going to start working on the issue! I'm so happy, as i found out about the driver issues AFTER i ordered the "lap"top.

https://forums.geforce.com/default/...re-new-drivers-look-for-a-nvidia-response-/9/

Until it is fixed, would you recommend me using the modified Vbios and the 327.23 driver? Should it be able to overclock and have no throttling? Apparently the np 9570 has excellent cooling, and it better for its size, haha. I haven't really touched any gaming computer in the last year and a half, and i plan on getting back into it.

Anyway, i just thought i'd let cha guys know about that post. I hope you're as excited as me at the prospect of the 880's finally being fixed.

Any advice for me is greatly appreciated!

The 9570 has fantastic cooling but the 880M is just a hot card. That machine was built for 110W TDP (780M), 880M is 122-125W TDP. Modded vbios will have 90C temps in that machine after an hour or two of gaming. If you are unlucky, you'll hit the 94C throttle point but my 9377 never passed 93C with the mod (outside of overclocking with high voltages) so I would say you will see between 88 and 91C in a 9570.

I would run 337.88 or 332.35 drivers.

Overclocking is not practical for regular usage but for benchmarks they will go pretty high if you keep them cool.

Thank you very much for your response! I'm glad to hear you are confirming the laptop has great cooling. Temps upwards of 90c do scare me quite a bit and i hope there are things we can do to prevent that. Would a notebook cooler like the "Cooler Master NotePal X3" help with temps?




How-come you recommend 337.88/332.35 drivers over the 127? I thought they contain a mechanism that searches for the hardware flag and throttles the card.

Thanks again,

J

 

A notebook cooler will always shave off a few degrees I don't personally use one though.

That supposed flag has never reared it's ugly head with me and the 337 and 332 drivers were the most stable drivers I tried on my system. My system came out of the box with 332.35 and the only reason I went to 337.88 was because of the poor performance in watch dogs.

Thank you very much! I'm tempted to use the 337 drivers now when my laptop arrives, unless anyone chimes in with warnings or other recommendations. Hopefully nvidia is going to fix their bios soon anyway, hopefully!

 

As soon I start 3DMark11, driver not response appeared. I OC my 880M clock +50 Mem +400 only. Any idea how to get it work. I'm using mod vBios from tech inferno. Thanks

 

i cant answer that, but i know in order for others to answer they will need a LOT more information. Like windows version, driver version etc.

 

That is the hope as well. As it is Sager has had my machine for a week now to replace a defective GPU...

Stock voltage won't give you much room to overclock. Bump it up to 1.025v and you should have enough overhead for a small overclock. These are Kepler pushed to the limits and don't seem to be binned all that well...

The clocks are not bad for kepler to be fair, it's just at the design limits.

 

If they would have binned them better, they could have been great. There are 780M that can do 954 at 0.968 while the 880M cards overwhelmingly need 1v. If they had binned them properly, the heat difference from the RAM would have been offset considerably and nobody would be upset to have them.

The 880M is becoming the 4930MX of the Kepler GPUs...

 

How do you mean?

 

Runs ridiculously hot, performs worse than its predecessor, and just very inconsistent in general.

 

Since I'm no pro in benchmarking I decided to stick to gaming to be practical . Watch Dogs on Ultra settings plus E3 texture mod and there was still stuttering and random stoppages during gameplay. Does throttling factor into this? I repasted with AC MX-4, flashed modded vBios but no OC'ing and the laptop sits on a Notepal X3 cooling pad. Temp on the high hovers below 90C-ish and low/idle at 44-46C. It's winter where I am btw . No Intel HD4600 present

 

It stutters on my desktop 780 Ti as well, it's just a badly optimized game. Put textures on medium and most of the stuttering goes away.

I feel like I'm one of the few that don't have problems with Watchdogs stuttering. Things were ironed out extremely well with the second official patch although ultra textures still require more than 3gb VRAM which is likely why a 780ti would encounter problems. TheWorse mod now it's complete makes it more demanding with extra pedestrians and effects and I do get some stutter if I turn everything on with that mod.

 

With SLI 780Ms no wonder mate . One single 880M has been brought to its knees by this game

 

I just gave up on that game. Won't make the mistake of buying another Ubisoft title in the future, at least not for the PC.

 

New ones are performing much better. This is Bioshock Infinite, a game that used to throttle horribly.



Notice how the core, temp, and load are generally linear and its boosting most of the time. That old slave was definitely defective but Sager opted to replace both cards with new ones and I am happy with the difference but they still have issues and hit their power limit too quickly. Still, its pretty amazing seeing them synced so tightly.

I also got a stock 13,495 score on Catzilla which is impressive for no CPU or GPU overclock, again boosting most of the time.

3DMark and other benchmarks besides Catzilla including Valley all throttle.

 

The 880m always rides close to the power limit. Glad it's sorted for you.

 

It wasn't sorted right away... It seemed to sort itself out after Bioshock froze but it's working now, won't complain.

Honestly I don't see the throttling problem here. My 2nd card throttles down to 954 MHz briefly when it gets above 80c. Even then it still boosts sometimes up to the max. It usually hovers around 970 to the full boost speed. my first card remains boosted the entire time of testing. I'm beginning to think its a motherboard issue for people? Does this throttling below the stock core only happen on older hardware or something?

 

@SemiConductorJ
I had throttling problems all of 20 minutes. Once that was sorted out. No more throttling.
And it's not a motherboard issue for people. It's a temp issue.(Or power or nvidia driver slow down)
Any type of core drop during intense play is still throttling. That brings on stuttering and screen tearing as well.

@etherm
Sorry, but it's suppose to be a strait line all the way across. Not a bunch of up and down lines, but if it's better than what you had. Then more power to you. But it's still throttling.

 

The odd dip may be a loading screen or menu. Boost should be fairly consistent but due to its very nature it will fluctuate a little.

 

Its a moot point, they failed again. RMA process started.

Looks like no over clocking for you my friend....
Look on the bright side.....the 980M's should be out soon. Now that might be a proper upgrade for your situation..... Although that could take months....
It's one of the reason why I didn't grab a p570wm3 just yet.

 

That's terribly unfortunate. A system that can't have the crap overclocked out of it would be absolutely worthless to me.

 

P570WM was discontinued by Clevo, nobody knows if there is a Haswell-E replacement coming.

Wasn't overclocked. Stock vbios. Xotic is seeing if they can replace the cards with 780M this time since this is my second hardware failure since I got the machine in May.

This time the cards will work for awhile but then artifact and crash. I've never overclocked the memory and they aren't even getting that hot but it would seem that the memory has errors. What's really annoying is that it can happen in 15 minutes or 4 hours so I thought it was just a game bug until I started noticing my core locking at 993MHz but my frame rate dropping from the 90s to the 20s and both cards dropping 10C.

Its really infuriating but they are being extremely accommodating about the issue.

As to this last part. It was already explained what would happen and what you would need to do to fix it.
And the second fail, not so easy to fix since that would entail swapping components or in your case...cards. Because part of the card fried, while the gpu die is in 100 percent working order.
Which still can happen if you get another set of 880M's. In your case I would push for 980M's and be allowed to run 780m's till they come in stock....Just a suggestion.

 

Well I would be happy with 780M cards since the machine works flawlessly with the exception of the video cards. That's what I would have had were I to have bought my machine two weeks before that, maybe even a week. It's just about guaranteed that a pair of 780M cards will overclock past my 880s with much lower temps anyway so I'd at least be getting the performance I paid for when I bought the machine.

Obviously if they have me try another pair of 880M cards, I'll push for a pair of 970M cards when the next pair of 880M inevitably fail. 970M would be the logical cards to replace them with from a performance perspective so I wouldn't take issue with them not being flagship cards since they are said to be 30% faster than 880M.

As for my current cards, I'm not 100% sure that there is nothing wrong with the core either. The cards didn't start with this core locking at 993MHz but performing like they are running at 400 garbage until the crashes started. Who knows what the real issue is. -_-

I should have taken the offer for a P570WM with a 15% restocking fee when I had the chance but that would have been another 650 bucks and I would have had to completely reconfigure the machine. :/

I'm am still 100 percent sure there is nothing wrong with the core.
What is wrong with the card is the coils, but no one seems to understand this after 7 months.
But like with any forums...to each his own.
Hope you get your problem fixed, because in the end...Mine ran pretty much flawless after it was fixed in the first 15 minutes.

 

John, do you have a post on how you fixed this? Thanks.

 

There is no complete fix for this because it was a design flaw. You can only work around it. the coils heat the card up to hot for the memory chips to operate. While temps will be fine on the core.
The only real way is to run test in a normal environment, then turn around and run the exact same clocks and voltage under really cold condition. In some case you can hear the card wine if you listen carefully. I used 8 pound copper blocks to test the theory and even those blocks heated up pretty darn quick.
Now running max fans in a 90+ degree room with stock clocks and voltage and locked at 993/1250 for gaming i was perfectly fine and gamed with no issues or down clocking or under vol ting. But i also tried different pads and grease to see what would help. Along with re modifying the Vbios to accommodate.

880M's are a work in progress and we quit working on it.

Side note:
And the 980/970 wont be getting any easier either.... As to the modding part....That's a work in progress as well...

 

Can you point out the components you are talking about? Thanks for the reply.

 

The only three other components that touch the heat sink.

 

The only three other components that touch the heat sink.
The two big ones.

 

These three things?

 

Yep, those are them.
it seems to be more of the two bigger ones though.

 

Are they different components that what are used on the GTX 780M?

 

The ones on the 780M's get no where near as hot as they do on the 880M's. If that were to stay cool then your 880M would run like a champ.

 

Do you think this is related to the 880M having 8GB RAM vs. the 780M having 4GB?

 

That i don't know deadsmiley. All I do is compensate and try to get the most out of what I paid for.

 

Yeah, the 880M isn't what it should have been. Kinda sucks for a lot of people. I feel like I got one of the "less bad" ones and it still isn't good.

 

Not sure what type of card I had but it seemed like a pretty good one. and that was back then. Wonder what it would do now....

 

Looking at images of the 780M and 880M...

The 780M R22 is marked with M141-03
The 880M R22 is marked with M061-03

It appears these are different part numbers. A quick google had netted me nothing so far.

 

same here. a big fat nothing on the internet radar.
