ASUS G750JY... a slap in the face to G751 owners?

[Richdog]

I mean seriously, ASUS are bringing out a new version of an old and classic design with a 980M, that I am sure they are aware people prefer (otherwise logially why release an old design?) due to the sleek back design and white keyboard keys that are easier to see and read? Can they have any more contempt for their customers, ie: G51 owners? Absolutely bizarre. :confused:

So yeah, I am now really annoyed as I would have loved to buy a laptop with that design and the G751 specification...

@Hmscott & @Kanecvr: This could be a long discussion because the real truth is somewhere in the middle. We should stick pursuing the main target, on how to lower the temps of the laptop instead of debating on how the system should have been designed. I'm part agreeing with Kanecvr because the case does need a better air recirculation and I'm also part agreeing with Hmscott because maybe the engineers from ASUS did take into consideration the intake of cool air using the available holes/orifices. And as a proof for what you both say, there is a another thread started by ExpatGamer in which he used an application "Notebook Fan Control" to raise the fans RPM. You can see his results here: http://rog.asus.com/forum/showthread.php?55539-G751-Fan-Control-and-Overheating . Hmscott already saw the thread and knows what I'm talking about. What he proved is that the case needs a better air recirculation and that the system is capable of offering it by raising the RPM of the vents. So you both were right in what you stated: the system needs more fresh air and the cooling system is capable of offering it.

Also yesterday I spent my entire day testing the Undervolting method using Intel XTU which I've seen at Hmscott. The results were positive and the temps are 5-6C lower now with a -90mv on both Dynamic and Proc. Cache voltages. You can see more details here: http://rog.asus.com/forum/showthread.php?52467-Got-your-new-G751JY-G751JT-G751JM-Post-your-review-te... .
This undervolting combined with a higher RPM of the vents and maybe a repaste from the Warranty service, will bring this machine to the temps which we have been used to see in older ASUS G series models.

EDIT: @Hmscott: I have a question for you. During the Undervolting process I saw that for the Manual tuning we also have the ability to lower the voltages on the next slides:
1) Processor Digital I/O voltage offset
2) Processor Analog I/O voltage offset
3) System Agent voltage offset
I don't wanna change these values without knowing what the result may be. Do you have any ideas about them ?

NitroX, the debate is good as it allows us to share / merge experiences in engineering theory and practical lab testing. I think a combination of the 2 methods - sealed case air draw from front to back for non-heatsink'd components, and an independent sealed heatsink/heatpipe/heat-exchanger cooling system cold air draw combined could be the next evolution in cooling. With the next generation might include Peltier active cooling while plugged in to AC.

But, to your point, developing practical methods with what we have is good too 🙂

The 4700HQ only has those 2 voltage tunables, if your processor has more, then you can refer to the onboard Help in XTU for descriptions of the tunables, and hit google/Intel for additional details.

Like with the "Turbo Boost Power Time Window", there isn't a lot of information and discussion on it, not many people dig that deep into it and post their results. And, for "Turbo Boost Power Time Window" specifically there isn't an entry in the XTU Help - there are other close names but not the exact name. BTW, setting it up from 8 seconds to around 28 seconds, like the 4700HQ has, seems optimal - but you can also get away with setting it to the MAX setting of 999999.

In this case I can't test it, as my processor doesn't allow it, so you get to be the "first" 🙂

You may crash, so be sure to back up your stuff, don't have important things open, and after a crash already do a disk integrity check!

I went through this and didn't trash any data or lose a disk, even with RAID0, so it is possible to make it through unscathed, I hope you do too 🙂

Got it, sir 🙂 ! I will first document myself about those options and then I will start messing up with them. It seems that the MB used for G751 allows the users to change more options at the CPU/GPU. Hell, I can even overvolt my GPU using GPU Tweak, though I wouldn't go so far for the moment to avoid losing the warranty. When I will start changing the other options be sure I will come back with the results. Since the system runs at the maximum negative offset for both Dynamic and Cache voltages I think that it could handle a bit more Undervolting, so I'm eager to reach it's maximum potential.
Btw, what does Turbo Boost Power Time Window actually do ?

PS: I've also tested the temps in AC Unity, over a 2hours period in which the game ran in an idle position stressing the CPU to 75/80% and the GPU to about 97/98%. The maximum peak of the CPU was at 82C, and the average temp was about 78C. That is quite an improvement I can say. The GPU also peaked at 73C. Yesterday I even ran the game with a +135Mhz Core and 5700Mhz Memory and the game ran very smooth, with a maximum temp of 86C CPU and 77C GPU , also in AC Unity.

Hi all I am a bit confused. I was about to purchase G751JY over the G750JY because of the IPS display but then I found this

according to the specs they advertise in Greece u get

G750JY
Monitor 17,3 IPS LED 1920 x 1080, Intel Core i7, 4710MQ - 2.5 GHz, Nvidia GeForce GTX 980M - 8 GB, RAM 16 GB DDR3L SDRAM, HD 1 TB 7200rpm,
2 SSD (2 x 128 GB), Blu-Ray (Write)

G751JY
Monitor 17,3 17.3" 16:9 IPS FHD (1920x1080) anti-glare, Intel Core i7-4710HQ - 2.5GHz, NVIDIA GeForce GTX980M - 4GB GDDR5, 16GB DDR3L,
HD 1TB 7200RPM, 1 SSD (128 GB SSD), Blu-Ray (Write)

The price difference is only 150euro (G750JY is more expensive), which would u buy and why ????

Thanks in advance

Guys, the G750JY has a download support area:

Looking at the manual...

Good news, the battery is removable.

Not so good news, there is no mention of a BIOS or Switch to disable Optimus - no mention of Optimus at all.

There is a new setting in the BIOS screen shown: C-States

On laptops that setting usually is paired with an Optimus enable/disable option, and is a problem for Nvidia GPU's. When Optimus is enabled and C-states is enabled, the Nvidia GPU can have ACPI errors and to stop those ACPI errors you need to disable C-states which also stops Optimus from working.

I am hoping that Asus has combined the Optimus / C-states setting and if disabled will disable Optimus... 🙂

But, I don't know if the video will still come through the Intel iGPU, or if the displays external/internal will be fed from the Nvidia GPU.

I would give my left nut to get rid of this red keyboard and hoping the new one with white light will be compatible with this one then.

I don't know. Unless a good keyboard is that important to you, almost everything is worse about that model... Optimus, worse cooling, bulkier... removable battery compromises the design a lot, it take up to much valuable space that would normally be used for the cooling setup.

8GB 980M cards would be nice, but you're certainly paying a lot more for that if the model you buy has one (built-in to the total cost, of course).
