Mabuti naman at walang issue na ang speaker and subjectively i prefer asus' design mejo streamlined kasi and modernist.

Well for me i decided and pulled the gun on asus g751jy. Its slightly cheaper now and ive heard that noise and cooling is the best. As for the desktop class cpu of np9772 its a compromise im willing to take since most games require gpu horsepower and the i7 mobile variant isnt far from the desktop i7.

Anyways thank you so much for sharing your thoughts on the matter, i think ill be migrating now to the other thread aptly named on my unit.

Salamat!

 

Man, this anticipation is like waiting for Christmas as a kid. Especially when you're going from a measly 2.5 GHz T9300 system with a GeForce 8700M GT running Windows Vista, to the i7-4790 processor and the GeForce GTX 980M video card. I'm now in Phase 3 and REALLY wish I didn't have to travel out of state from the 10th to the 15th as I'll either have to wait until I get back for the laptop to arrive, or have it arrive a day before I have to leave and then be thinking about it when I'm away. (I don't want to take it with me and try to set it up at the hotel. Too much of a PITA). It seems like everyone in here is super happy with their system, and I have no plans for overclocking in any manner whatsoever, so the cooling system seems adequate to me. (I went with the IC Diamond Thermal Compound on the CPU and GPU anyway).

 

Ok pre, pm lang ...

 

Just remember guys all non English text must have a translation below it for the sake of the moderators.

 

I get an ID mismatch (MD5) on Premas 980M vBIOS. Anyone else? @Prema

 

Everyone gets that on all Clevo's, that's normal. Reason being the device ID being patched on the fly by BIOS to add model HWID and is not actually displaying the current GPU device ID as present in vBIOS.

 

I definitely know what you're talking about. Was upgrading from a similar Core 2 system (X9100) with a GT230M...
And believe me, you will want to tweak your system, because its so easy and rewarding.

 

Thanks. I didn't quite get the explanation but I don't doubt you.

But then, why even print the checksum? Since all Clevo users get a mismatch and all specifically tested laptops listed are Clevos.

 

I already modded the nvflash to not print an additional confirmation request and to flash a modded vBIOS at all. Stock nvflash would tell you to go home when trying to flash a mod.
(Times of just adding -4 -5 -6 and flashing in DOS are over, this stuff is locked down as it is).

 

So I just got an email that sager is sending me a new GPU to replace mine after we did some troubleshooting. They are sending it to me with a hold on my credit card such that I can keep the laptop (awesome) I will update when I get the new card.

 

Good luck with the lottery! My second 980M is 63.5% so I'm very eager to repair the first one.

 

Well honestly at 64.2 (my current one) it can't get much worse I feel on the asic quality scale that is a D- haha

Before I send back the old chip I will need to re flash the vbios back to stock. Flashing the vbios initially was easy but if you guys don't mind giving me a guide to follow that would be greatly appreciated. I want to make sure it is done perfectly. Now would not be a good time to mess up the chip myself :/

 

Search my name and ddu our safe mode in this thread or p750zm thread. I did a point by point guide.

EDIT: This was driver and flash troubleshooting
To be clear on the order:
1) Download the stock Nvidia 344.75 driver, the stock vbios, the modified vbios, and DDU.
2) Verify the SHA-1 on all files downloaded to make sure not corrupt
3)Boot into safe mode
4) open DDU
5) verify that the option to disable windows auto driver search is selected
6) run DDU
7) reboot into windows normally
8) go into control panel, go to device manager, disable display adapter
9) flash the stock vbios
10) reboot
11) verify that display adapter is still disabled
12) flash modded vbios
13) reboot
14) enable display adapter
15) install driver 344.75
16) reboot
17) check to see if everything is working normally
As an added reminder, there may be flashing of the screen or the screen may go black temporarily while installing the driver. MAKE SURE YOU GIVE ENOUGH TIME FOR IT TO FINISH INSTALLING THE DRIVER. This time varies by computer!
Happy hunting!

Edit 2: You will need NVFlash and a stock vbios. Also, obviously, don't reflash the modded bios in step 12 (so skip 11-13), and use whatever driver you would like!

 

I´m being overly cautious here but, the iGPU isn´t visible in device manager. When I disable the 980M for the vBIOS-flash it will kick in right? Don´t want to be staring at only a black screen..

 

That's because there isn't one.

 

Thought I read as much. So what happens when i disable the 980M in device manager?

 

It goes to the 800x600 default and uses a generic video driver. But it's all still the video card. Don't worry about it, it will be fine!

Edit: I created threes instructions for a person having issues with a bad flash and couldn't OC, but had video still. Use common sense for what applies. If it is the first mod flash, ddu, disable adapter, flash, driver with reboots in between as those directions point out. Also, if flashing from mod to stock, reset msi afterburner or nvidia inspector to stock instead of overclock before you begin just in case!!!

 

If you disable the 980m it renders the desktop on the cpu and uses the gpu to simply pass through the image to the monitor.

By CPU I really mean the CPU cores and not the iGPU.

 

Yep. Basic VGA (maybe VESA) graphics, no 2D acceleration and no 3D at all.

 

The true old school way of doing things from pre 3d accelerators This is sometimes why a faulty gpu will output a display until you install the drivers as that moves rendering onto the gpu.

 

I have successfully reflashed the prema vbios :/ looks like the file I saved was not the original vbios. Can anyone send me a dump of there stock vbios?

Edit: just kidding I now see that prema has the stock vbios available on his site. Got it flashed back to stock now. Thanks for your help.

 

Thank you for the correction. I do apologize for my earlier statement!

 

Prema's good like that That's why passing him some beer money is a good idea

 

anybody know if this is a good maufacturer:
their computer is not listed at the notebook manufacturer section

https://www.pugetsystems.com/laptop.php

 

That pump is embedded in the evaporator.
Perhaps it will do when mixed with a loop heat pipe.

 

What happens to the HD 4600 embedded in the 4790K? Can it be enabled?

 

No, the iGPU is physically not connected. That's why he wrote "uses the gpu to simply pass through the image to the monitor." If it would be connected, it wouldn't use the external gpu for that.

 

If that's true the 4790K will never reach the Max TDP of 88W at stock settings.
Have anyone measured the actual power draw at full load (Prime95 "In-place large FFTs")?

 

You say that like it's a bad thing.

 

Not for overclocking for sure! lol

 

I've noticed electrical noise from the speakers :/ It begins when I start a game and has variying pitch depending on what's on screen.
Nothing to be done I suppose, atleast it's not as bad as in that video earlier (ingvarrs I think). It gets drowned by fan noise when they ramp up.

 

Absolutely that's why I donated $20 when he released the bios and vbios. I also donate for things I use. However since I already donated in not sure I'm going to donate more as money is tight for a bit...

 

why do people seem to get issues with the speakers on this machine?
is it specific for this particular model,or for sager/clevo?or a bad batch?
is there a way to fix it?

 

I believe I get it also from time to time so I think it is just like stated above a result of electrical noise. If true then yes it can be fixed by further insulation of the culprit. This wouldn't be easy as finding the issue would be very difficult. If it is the same noise I hear then it only happens every now and then and then goes away after a few seconds. Which then confuses the fact that is it really electrical noise or not. Either way yes it does exist but unless you have one of the laptops which is was really bad it's not really an issue but rather we are a group who analyses ever aspect of the machine so little nuisances for most can seem like big problems. It's the nature of a tech forum.

 

It's pretty much every computer in existence. The problem is wires connecting the amplifier to the speakers (when built in) or to front panel headphone jacks (for towers). These wires pass over, under, around, or otherwise in close proximity to other circuits in the chassis. They pick up RF noise from these other circuits exactly the same way that a radio antenna picks up RF broadcasts. Some designs are better than others, some are worse, but they all suck to one degree or other.

It can't be fixed. Even if you were to shield the speaker wires they have to be exposed where they connect to the amplifier and the speakers. Noise will get in at those points. It's inevitable. It's just how electricity and electromagnetism work.

There are some things you can do to work around it. Environmental noise can mask the electrical noise from the speakers. Using the audio out jacks with headphones or external speakers eliminates the wiring that picks up RF noise inside the chassis. Using a USB sound card moves audio decoding entirely outside of the chassis.

 

well yeah,but i do not see this being mentioned on other laptop model threads,kinda sad its on the sager.does it still appear if you listen to like music on reasonable volume?without blasting it all the way up?

 

I have. Even when I had gone to 4.4 or 4.5 all cores before de-lidding, I was getting 76 tdp tops. So yes, the tdp is lower than the max and won't become a concern unless doing mods to run higher multiples. The average user will never hit the max tdp!

 

Doesn't mean that other models don't have problems. I've had problems with every notebook I've had my hands on: Acer, Apple, HP, Lenovo, Dell, Leading Edge (remember them?), Toshiba, WinBook. Probably others that I've forgotten about. Noise from every one of them. Some more than others, some less than others, but every single one. Why don't more people complain about them? I dunnow. Maybe it's just because most notebooks have worse things wrong with them for buyers to latch onto.

 

Very good news to me! Thanks a lot!

 

is it influenced by the volume that you are listening at? cause ive noticed some kind of tremble-like sound when setting high volume on my current laptop and on others aswell,so meh,if it aint noticeable on lower vol,then its harmless.

 

Just did my worst pastejob ever. First time using Gelid, it was a mess. Too much and tried to remove half, what a blob lol. Next time Ill heat it first. Temps in XTU the same as with stock paste (proper pastejob by mysn btw). I will do some tests then check the spread and repaste.

What surprised me was the fit of the heatsink. It was less of a hassle then with my HM. On that I have to wedge it abit around the fan. With this I just drop it straight down in a perfect fit.

 

It isn't perfect unless it sits perfectly on it to spread the paste. But yes, it is easy. To get the best seating possible, it will take practise.

As close of contact as I've had so far...

 

Scratch that. Much worse temps in Heaven. I don't even wanna see what it looks like inside..

 

Try, try again. Also, check the contact as my photos show. My spread was horrible before lapping because the cpu was badly concave! But worse temps than stock, that is a mounting issue. Once you set it down perfectly, do not wiggle it. Apply continuous downward pressure or air can get in.

 

Before I did my lapping I took very careful measurements of everything and it seems as though the heatsink is convex to fit the concavity of the CPU not much but ever so slightly. This is either by design or mine just happened to be that way. Either way after polishing and lapping they are both perfectly flat and temps did drop significantly so if they did do it by design they failed...

 

Btw, new heat sink and a finger sander was ordered last night. So I'll check fit first, then lap the heatsink (all parts used with any thermal interface material including pads) (and clean up the cpu), apply the thermal pads(fujipoly 17w/mk), and check where it's at. If the one corner is still high, then the mb gets pulled, mounting arm leveled, and pictures will follow. Also, @superkyle1721, how does your contact compare to my posted pics today?

 

I would say mine does appear to be more uniform. I have plenty of paste so what I'll do is in a couple hours I'll pull my heat sink and take pictures. It's really extremely even now that it has been lapped and polished. Plus I just trusted my first paste job so I'm curious to see if it is even a good one or not. Updates to come.

 

After lapping, the one corner that previously gave an issue on contact (before my RMA) reappeared. Because of that, it will have to be readjusted once more for that corner. If you have better contact, then you did an excellent lapping job considering the CLU did practically nothing for temps. That is usually seen with either poor contact or amazing contact between lapped surfaces. Perfect contact eliminates the benefits between a high quality paste and liquid metal.

Edit: New EC for our laptop!

 

Ok dumb question I know what the embedded controller does but are there any stability benefits in the update or what is exactly updated with it?

 

Anyone know how to remove the speaker grill without having to take apart the entire laptop? I need to find out what is causing the speaker buzzing noise.
