Can any reseller tell us what the Silent Mode is and how it works?

Hey, We as customers don't have a clue really but are very interested in this silent mode feature as well all know that sagers can get loud. Could you tell is whether it just slows down the fan like the previous 5793 had an option for? or if it underclocks the machine and slows down fans?
I'm sure this is information everyone wants to hear so if you know please tell us. Thanks.

 

It would be sooooooooo great to be able to use the NP5796 in a library or something

 

My best guess is a possible disabling of the GPU and running either on a IGP or a very downclocked one, paired with a low fan speed, and possibly,better fan quality

 

their is no IGP on the Chipset in these notebooks though. I would hope for downclocking and better fan quality.

 

it should downclock and undervolt the CPU and GPU to lower power consumption and heat to not need the fan to come on.

 

How loud is it when it is running simple applications such as MS Word, firefox?

 

what about hybrid SLI thing... ???

 

This is might be best in another thread, but does anybody know how the noise is on the NP8660 in its various modes? Thanks.

 

no one knows..YET!

 

hybrid sli will not exist on these models. It requires an IGP

 

So in this mode, how long does the battery last?

 

none of the resellers are telling us. they havent run any tests for us on the 8660 model that weve asked them too. i dont know if its because theyre busy taking orders or more NDA's or what, but it does make me a little paranoid.

 

Sorry about how you weren't getting any information; I must have just overlooked this thread. I hope you can accept my belated response

Silent mode locks the CPU at its lowest multiplier setting, and keeps the fans at a low RPM as long as no heavy tasks are launched. This means that you can run email, word processing, and web browsing in silent mode without the fans going mad . It will extend the battery life, but I don't have the exact figures of how much (I'm going to guess at least a half an hour? It's possible I'm wrong).

Silent mode is available on NP5796, NP7220, NP7660, NP7680, and NP8660.

 

thank you, didn't even know you had account on here dark smiley. Any response is better than none!

 

Yeah, it'll be added soon when Gophn updates the Clevo guide to include the new laptops & reseller updates :]

@vestibule: what tests did you want run?

 

;>.> so basically its like I said in another thread, anyone using rmclock with the np5793 can do the same thing.

 

Indeed they can

 

Could I see your product line in person because I live close or is it an online only business? I want to see the quality differences of an 8660 and a 2096.

 

Sorry ~hi2u~, but we're currently online only, receiving each laptop from Sager only once its ordered. Hopefully once we get enough business we'll expand to retail as well. If you have any specific questions that you need answered, though, please PM me.

 

Does Silent Mode downclock the GPU as well? It's probably equally power-hungry as the CPU...well, I have little laptop experience so maybe that's not very correct.

 

the resellers are not exactly not telling us, they dont have the specs. Even some old ones that they may have had are completely redundant with the new GPU's and any other updates that occured. the only people that could tell you are sager (who wont) gophn and exclusive others. The M860tu ES models are notoriously hard to get.

 

When I contacted the Reseller Account Executive from Sager, the response didn't include anything about the GPU being downclocked, just the CPU. As far as I know, it's not touched.

EDIT: @heliosvector - as far as I know, Sager will respond. Or maybe they just respond to me, since I'm a reseller. Who knows? If you have any specific questions, ask me and I'll pass them on.

 

yes, it downclocks the gpu aswell.
We may also be able to downclock the lowest multiplier to gain even more battery life on silent mode since it only locks it to the multiplier, not downclock.

 

I hope the N8660 will have something like a hybrid graphics system found on some Sony notebooks. The GPU can be switched off to integrated graphics without the need to reboot. As a result, battery life is much more longer.

SOURCE:
"a revolutionary hybrid graphics system lets you set your graphics performance on the fly without needing to reboot. A simple hardware switch enables you to toggle between an internal Mobile Intel® GMA 4500MHD graphics chip for optimal power consumption and an external NVIDIA® GeForce® graphics chip for more robust performance. For big presentations, utilize the more robust setting to bring your on-screen elements to life. But when the presentation's over and it's time to catch up on e-mail before your flight, simply flip the switch—no need to shut down your computer—and utilize the internal graphics setting to enjoy lower power consumption for longer battery life."

 

Read the other posts in the thread before posting yourself. The 8660 has no integrated graphics, therefore no hybrid graphics.

 

yes, sager dont care too much for us normies lol!

 

Nice. There would be almost nothing stopping me from getting the 8660 if I can get 3 hours doing word processing with everything turned down. I do have a bit of a life outside of gaming

 

sent you a pm darksmiley

 

gophn said about 2.5hours, but we dont know what config thats it. with the 25w p9500 or some other 25W we may get more. even more with downvolting.

 

Is there any danger in using the silent mode for prolonged periods of time? Like every day for months? Also, how loud would the laptop get with just every day tasks like word processing and web surfing WITHOUT the silent mode?

 

not a single person on the planet has the machine (or shouldnt) so that cannot be given an answer at the moment. what i can tell you though is that bigger fans are quieter than small ones. they just are. Less physical interferance with the air makes less friction= quieter fans. thats the extremely simple version.

 

Ok that's good to hear. I'm kinda worried that this thing will sound like a jet every time I do simple tasks.

 

It also has to do with the velocity of the air moving out of the system - the higher the velocity of the exhaust air, the higher the noise, and conversely. The basic problem is that air-cooling depends on how many cubic inches (or millimetres, or centimetres, or feet, or ...) of air per minute you can exhaust from the system. Since the diameter of the fan opening is fixed, the ability to remove, say 1 cubic unit of air per minute depends on the velocity of the air, and thus the speed of the fan (let's not get technical about the difference between velocity and speed).

For example, assume two fan openings, one being 5cm and the other being 8cm in diameter. Since Area = pi x r^2, the first fan opening has an area of 19.63cm^2 and the second an area of 50.27cm^2. Thus, to move 1000cm^3 of air per minute, the first fan must impart a velocity of 50.94cm/min to the air, whereas the second fan need only impart a velocity of 19.89cm/min to the air.

That means the air coming out of the first fan must move about 2.5 times faster than the air coming out of the second fan, even though the second fan is only 1.6 times bigger than the first as measured by diameter. I don't know what the correlation between airspeed and fan rotational speed is (and I'm not going to work it out now) but if it's linear, that means that the smaller fan must move 2.5 times faster than the larger fan, just to achieve the same cooling effect.

 

Not to split hairs, but I think the velocity of the air has to do with how much turbulence it generates, which what you end up hearing. So I suppose even the design of the outlet could have an impact on the noise level, though I think that would only be a minor factor.

I think slower moving fans also produce less noise because there is less frictional noise from the bearing.

 

As a response to everyone on this thread, I would like to make one thing clear that seems to have been a bit of an odd point. I just got final word from Sager:

Silent Mode does NOT downclock the GPU.

On the fan note, I can't say anything about how loud the fan is; I don't currently have a system - sorry!

 

The laptop shouldn't be loud while doing every day tasks besides gaming right?

 

No, it shouldn't. The fan will be kept at a low RPM. How low? I'm not sure, but I doubt it will be above a whisper.

 

NOOO!!! I suppose the Silent Mode button command is controlled by the BIOS and can't be altered to support a GPU downclock. I noticed that the nVidia website doesn't say anything about Powermizer for the 9800M...looks like we need a programmer to write us a little GPU downclocking app.

 

You can always yo nibitor to change throttle and 2d clocks and then change the voltages

 

oh well, atleast there are third party ops to do the downclocking of the gpu for us.

 

Is it confirmed that the battery last at least 2 hours on m860tu?

 

Nothing is confirmed yet, sorry.

 

Since I bought a spare battery, could I quickly switch between the two batteries without turning off the computer?

 

I wouldn't think so, unless you had your AC adapter plugged in, of course

 

as darksmiley said.
I think Gophn had some specs that it will last longer than 2hours, but as dark said, this has not been confirmed as even ES models are hard to come by.

 

I for one am glad they didnt mess with the gpu in silent mode in any way. Messing with that would just create an opportunity for issues to arise. I'll be ordering this laptop in a couple days and when i do receive it i do not want an m15x repeat.

 

I suppose thats a good way of looking at it. I remember all the problems stealth mode created in the m15x

 

No, there is no danger in leaving Stealth Mode on at all times. When needed the fans will ramp up, and then go back to Stealth Mode when usage goes back to idle or very light use.

 

No, but you don't have to shut down either, you only need to go into Hibernate mode to change batteries.

Going into and coming out of Hibernate mode is much faster than shutting down and rebooting.

 

ah, didnt know that little thing. +rep for you.
