Well two RMAs were for 880Ms and this last one was for the keyboard and I had them look into everything else while they had it.

Your ASICs are close to mine (72.2% and 74.1%) so chances are good that these cards would run with such low voltage also but I'm not going to mess with it. When I tried adjusting the voltage on the 880Ms, they still power limit throttled despite the lowered power... I had them running 836MHz @ .875v or something yet they still power limit throttled in the exact same loads that they did at the stock voltage. Makes no sense.

 

Even chips with the same ASIC can react differently throughout the voltage/frequency curve.

 

Oh I agree. I don't intend to mess with it. I don't know how to modify Maxwell voltage tables anyway, it's not like Kepler. Still though, assuming he's still running stock clocks, 1126MHz boost at only 900mv is pretty impressive. I mean my Qualcomm SoC uses 1.175v when it is at 2650MHz core and that's with the GPU on idle base clocks.

 

True, my Titan-x needs 1.25V for 1.5ghz.

 

I once met someone who modded constant voltage into his 980Ti and has it at about 1450MHz core on 1.175v. He also has boost clocks = core clocks too, so it's a flat rate.

 

GTX980M SLI is faster than a single GTX 980 (200W).
If you want to get the P870DM "early on", then get it without GPUs (just the cooler) and through the two GTX980M in there that you already own...

 

Yes in titles that like SLI the 980M setup will still be ahead, but you will get less driver issues with the single 980.

 

Yeah that's the big tradeoff.

 

Hey ethrem.
I just ran heaven benchmark on my rig wich is same as yours except I have a 4810mq cpu just out of curriosity. I put everything extreme or as high as it could go. I let it run 4 times through. By the end of the 4th time through my gpus were at 83 and 86 and that was with auto fans . After the 2nd time through they were at 82 and 84 with auto fans . After the 4th time through and gpus were at 83 and 86 I hit max fans and they went right down to about 76-78 . My cpu stayed around 72-75 . My gpus and cpu are all stock with no vbios mods or overclocking.
I haven't cleaned the vents or fans for about 6 months so it's probably due. Will do that today and see if it makes a difference.
When I first got my rig I ran games without vsync and let the gpus run and they would run 82-84 . I only have 60hz panel so I set vsync In
games to 60 and my gpus run between 63-72 with auto fans.
I imagine if I left heaven benchmark running for 30 minutes to an hour my cards would probably reach throttle limit. But that's running the cards at 97-99 % usage nonstop . That's with auto fans of course. I think I just talked myself into cleaning my vents and fans today lol.

When the 980ms run wide open they do get warm. But with vsync to 60hz and a 1080 screen they don't even break a sweet.

Ethrem .
Is your rig thermo throttling on first run through without max fans or is that letting it run for quit a while.?

I have 72 games in my laptop and most are the latest Aaa titles and I haven't had any problems with sli other than a couple glitches like in farcry 4 witch was fixed . My sli has been working great for all my games. I agree driver support from nvidia hasn't been the best lately. But the last three drivers have been working fine and sli works with all my games except some older ones that only ever supported one.
A lot of people say sli sucks and is to problematic. But I have had the complete opposite experience with sli. It's worked great for me and haven't had really any problems to speak .



Here's the bottom of my laptop.
I cut out every other slit like another member showed a while back in this thread. I have a new bottom cover just in case I have to send it it for repairs so they can't say I modded the laptop.



Here's bottom off before cleaning vents .


Above photo is cpu vent. Not to bad.



Above is left gpu vent. This is by far the dirtiest one.



Above is right gpu vent.

 

Check out the second spoiler to see where the throttling starts. http://forum.notebookreview.com/thr...7-owners-lounge.753213/page-253#post-10107309

And yes if I turn vsync on 60, these cards run much cooler but what was the point of getting a 120hz LCD if I have to be limited to 60? Not only that, AAA titles like Witcher 3 that struggle to keep up 60 on ultra settings require max fans to not thermal throttle. Nice job on your cover mod. I'm not handy with things like that so I still have a stock cover.

 

Ok I reran heavan after cleaning vents and this is what I got.

Auto fans. Latest nvidia driver. I let it run continuous 4 times.

End of fist run gpus 76 and 77. Cpu 73

End of second run gpus 81 and 84. Cpu 74

End of third run gpus 82 and 87. Cpu 77 . Didn't reach 87 until last 45 seconds and about 10 sec after reaching 87 both gpus went to 1075 mhrz and stayed there.

End of 4th run I put max fans and it ended with gpus at 73 and 77.

 

I would just leave it looping, not benching, and monitor temps.

I suppose it's possible that the drivers have matured since HTWingnut did his review with this machine and 980Ms. He maxed at 86C with a +135MHz overclock and at stock, one card was 84C and the other was 83C. Those were tests on auto fans.

It would be nice if nVidia left the ability to undervolt Maxwell because you can get huge gains undervolting... Not to mention added stability through steady voltage instead of dynamic switching.

 

I did have mine looping and it wasn't benchmarking. Just looping through 4 continously and I checked temperature at end of each loop.

 

Lol I'm lazy. I set GPU-Z on each card and turn logging on and go do something else haha.

 

Every chip and heatsink will be different but it's true that as drivers improve along with FPS the GPU is working harder.

 

Indeed. I had Prema work his magic. This is a full test including all demos in 3DMark 2013... Note that its with auto fans.



No more 87C and throttle. No more worry about component failure due to heat. And the chassis itself is of course much cooler.

 

So you flashed your vbios on your cards.?

 

Yeah, we worked to find a stable undervolt. Easiest way to get temperatures down. Not to mention totally reversible. I debated on getting some liquid ultra but that's a much riskier alternative.

 

I'm glad you got your machine working the way you want. Now you can start enjoying it.
I only have a 60hz screen at 1080p . I know the cards run warmer trying to push 120hz screen like yours. I over clocked my screen pretty close to 100hz when I first got my laptop just to see how far I could go. I think I stopped around 90hz or so .can't remember exactly. It did run my cards considerably warmer. So I finally just settled for the stock refresh rate of 60hz and turned vsync on in games to 60fps and have been running it that way ever since. Been playing mad max with everything to max or as high as it will go and gpus run between 59-64 depending . Around 70 average for most other games so I can't complain.

But if you got a 120hz screen you might as well use it right.

 

By undervolt you mean core voltage correct.?
So if you were to overclock your cards you would have to bring the core voltage back up to keep the cards stable again correct.?

I'm also curious how low you were able to go with voltage before your cards became unstable. And what voltage did you decide to stick with.?
I know every card is different and I can't go off your numbers for my cards .just curious.

Sorry for all the questions .
If I was a cat I'd be dead .because curiosity killed the cat.lol

 

Curiosity killed the cat, but satisfaction brought it back!

@Ethrem, I'd be curious to know as well. As I mentioned, my cards are dang hot too and my ASIC qualities are just a bit better than yours if I remember correctly, so I might want to UV as well and could probably use your stable UV as a baseline.

I won't be overclocking my cards but yes I would have to raise the voltage if I were to do so. My cards would only stabilize at 975mv for boost. 925mv was stable for base clocks. I tossed Prema a nice donation for his time and I used Heaven as a stability test. Once that passed I ran through 3DMark. Not even a hint of instability. 962.5mv was close and 968mv would have probably been fine but 975mv was a safe bet and still accomplished what I desired which was the lower temps.

I'm also using the latest nVidia driver which may have actually caused instability at lower voltage.

 

Chips do need more voltage over time too so you do want a little margin like you have done

 

I mean not necessarily. Depending on how much extra voltage you give versus the absolute MINIMUM stable voltage, it may NEVER need extra voltage. Besides, the great thing about undervolting is when you have your stable voltage, even if it becomes stable over time, you have 2 ways of fixing it. You can flash a higher voltage vBIOS, or you could just use something like MSI Afterburner to increase the voltage manually without even needing to flash a new vBIOS.

Undervolting is awesome.

 

Yes indeed. Maxwell is especially voltage sensitive. I haven't seen such a finicky chip before. When I was playing with MBT before Prema stepped in, if I didn't lock a set voltage across all of the boost tables it would crash. I hope Pascal doesn't have the same dynamic voltage garbage that nVidia did to make Maxwell.

 

It will probably be worse considering that finicky voltage manipulation saves power.

 

Indeed but I'm hoping that nVidia only did that with Maxwell because they needed to milk 28nm some more. It hasn't exactly been a welcome change and has caused a lot of stability problems especially on the desktop cards.

 

Hi everyone! I bought 2 units of Notepal U3 Plus to use the total of six fans to cool my P377SM-A mainly in the summer when the room temperatures can reach 30 degrees celsius and more..

The whole 6 fans stopped working and i got to google why, and figured there is a resistance inside the spinning rotation controller that would blow up when always using the fans in maximum speed.

Contacted Cooler Master and they sent me 2 kits of fans totally for free! So here is my appreciation for their wonderful customer support and in case anyone is wondering my cooling pad looks like this with the 6 fans:

Spoiler

Kudos for Cooler Master for their awesome support and being so professional with the clients

PS: Cooler master was informed of this post so this post is my appreciation for their work and products

 

How much of an improvement do you get in max temps? I'm assuming you have a case mod to allow the extra air?

 

Actually I just positioned the fans right I the entrance of air. Didn't mod the case because I'd lose my warranty if I did so. Currently under heavy load I get 65 degrees in both guys and 58 on the cpu. In normal usage like Internet and YouTube it is sitting in 44 degrees

65C on 880Ms?!!? Jeez! Well now that I have an actual bed I actually need my laptop to be raised higher so maybe I should pick up one of those...

 

I did pick it up because 880M overheat like crazy... And that's mainly why I wanna get the new P870DM with 980M.. I'm not unhappy with the 880M as they run games at maximum settings and they dont throttle (with svl7 bios) but still... They are 880M's lolol

Enviado do meu SM-N9005 através de Tapatalk

 

The GTX 980 isn't that much faster than the 880M SLI and if you're using the modded vbios then the gap closes even more. The big downside of SLI is games that don't support it but the 880M SLI is still viable if you can tame it.

 

That's why I am considering dual 980M's

Enviado do meu SM-N9005 através de Tapatalk

 

The 980 looks to be far more overclockable than the 880M cards were.

 

Lol the 880M overclocked like no other mobile Kepler... It just burned hotter than any other mobile Kepler in the process...

 

Which meant you could get more out of the 780M as heat is your enemy, add to that maxwell is doing more than any kepler did.

 

Yeah tell me about it... Still though, if you have good 880Ms I'd hold off until Pascal.

 

Hold off until the games you are playing don't meet your standards really.

 

Or if you plan to do VR.

I just ran 3DMark 11 Extreme... I didn't realize how much of a difference CPU speed makes on every bench in 11 Extreme... The left is with the CPU set at 40x max, 47W, 71A. The right is 40x max, 57W, 105A.

http://www.3dmark.com/compare/3dm11/10405334/3dm11/10405377

 

11 has been very CPU sensitive for some time now.

 

That'd require me to buy three 980Tis and watercool them all with custom vBIOSes overclocked to all hell and an i7-5960X at 4.8GHz

=D

 

Have had this laptop since last Dec running with sli 980s, prema mod, 32gb ram, raid SSDs, Win10 and everything works pretty solid at 4Ghz. I've always had this one issue with control center. I normally run on an external display and control center will never open with the laptop display off. It just hangs when I try to start it unless I enable the laptop display. Annoying as hell!! I had this issue with win8.1 and numerous versions of control center. You guys have this same issue? Anyway to fix it??

Does G-Sync work on this laptop? I was looking into getting a G-Sync display but read awhile ago that people were having issues.

Has anyone changed out the leds on the front of the laptop? Anyone know what kind of leds I need? Thought it was so silly that you can customize the keyboard lights but nothing else!

Thanks =D

 

How likely does Sager NP9377- S aka CLEVO P377SM- A will be upgrade compatible on the new GPUs like Pascal?

 

Until they are out and tested it's unknown.

 

could anyone help me out, I'm only seeming to get audio out of the front two speakers. volume has to be low or the speakers distort and sound blown. not sure what driver to use I've used both drivers on the clevo website but they don't seem to be a solution. Should i try to update the Realtek driver?

 

The system uses a 2.1 speaker set, are you saying you are getting nothing out of the sub?

 

So Fallout 4 system requirements are out and I was wondering how this measures up to the NP9377 since they don't really give notebook specs. What do you think an i7-4910mq, GTX 980m SLI, 24 GB RAM, SSD will run it at based on this? Not sure if SLI is supported but if I remember correctly Skyrim has SLI support so this will probably get it.

Minimum
Windows 7/8/10 (64-bit OS required)
Intel Core i5-2300 2.8 GHz/AMD Phenom II X4 945 3.0 GHz or equivalent
8 GB RAM
30 GB free HDD space
NVIDIA GTX 550 Ti 2GB/AMD Radeon HD 7870 2GB or equivalent

Recommended
Windows 7/8/10 (64-bit OS required)
Intel Core i7 4790 3.6 GHz/AMD FX-9590 4.7 GHz or equivalent
8 GB RAM
30 GB free HDD space
NVIDIA GTX 780 3GB/AMD Radeon R9 290X 4GB or equivalent

 

A 980m SLI should run it at max settings with really good frame rate assuming it supports SLI.

 

Whichever way, 980M should burn this game.. I wouldn't worry..
