Problems with G750JW-BBI7N05

[UnfairAwesomene]

i got a Asus G750JW-BBI7N05 laptop at Best Buy, Returned it the first time because bottom bezel was bent in the middle showing the backlight LEDs, returned it the second time because the "R" key on the keyboard kept popping up, returned the 3rd time b ecause I got a recovery error (was on phone 20-30 min with asus telling me to take battery out, hold down power button for 30 seconds and then reset bios (with no success), then i was told to go back to best buy and have them fix it. the problem is, that they said they will run a diagnostic on it and it will take 5 business days. what should i do about this? (it has been 14 days since i originally purchased this laptop and 5 more business days to maybe it gets fixed?)

As you are using XTU, I wonder if you have overclocked the CPU? Did you increase the multipliers beyond stock?

If you did tune with XTU you can also reduce the heat output by adding negative voltage offset for the CPU and Cache. You can start with -50Mv, and keep increasing until failure. Or, you could do what I do, I started with -100Mv which worked fine on my JW, but my JX only allows -60Mv for long stable 100% runs.

I haven't used XTU stress test, but everything other benchmark and real world test I have run doesn't push the CPU into thermal throttling, even with 36x multiplier and no negative voltage.

The Cinebench test didn't put you into thermal throttling, did it? Anything else?

Everything was left at stock, Cinebench put me at 93-95 c.

As you can see from my Cinebench run, 3 runs in a row actually, I also saw 93'C as a high.

Now that you can measure throttling with XTU / hwinfo64, run Cinebench again and see if you have any thermal throttling during the run.

At stock settings you shouldn't be seeing any throttling. Is your ambient temperature particularly hot? Like 80-100'F?

[hmscott]

Here is the 5 minute XTU stress test run with max OC and -60mv CPU/cache offset, room temperature was 72.5'F



Here is the 5 minute XTU stress test run with stock settings, room temp was 72.8'F



Neither test had thermal throttling, and both tests had much lower temperatures than your's.

Did something happen to the laptop / environment where you are using it since the Cinebench runs to cause the temperature to go up so dramatically? Is the heat from the exhaust ports somehow making it back into the intake?

it is on a desk (yes wooden) but nothing blocking anything. back of laptop is 2 feet from wall, sides at 5feet+

Try the XTU stress run again in the open, away from a wall. Feel the air speed coming out of the laptop - it is a strong fan putting out a lot of heat, and it is reflecting back into the laptop.

I had a similar set up and had to move the laptop to the other end of the desk and tilt the laptop to fire the hot air into the open away from the walls. I ended up moving the desk around to face the middle of the room.

temp goes 90 - 96 (92-94 more common)
throttle: 3%

I wonder what it means when the range says 0 c to 97?

If you could use the Windows Snipping Tool to grab a copy of the XTU Stress test + HWinfo64 like I have above, it would be helpful.

Translating all that info to a few sentences of description makes it tough to figure out the state.

If you can measure the ambient temperature, room temperature, or at least give the outside temperature and a note as to whether you have heat/airconditioning on that would be helpful too. Your readings are too high, and I can't tell from the info you are giving whether it is a problem, or just localized environment temperature.

Doesn't tell me if that is Low to High, if so that Low is too High 🙂

You shouldn't be throttling at all, even 3% is too much. There is a Row in HWinfo that tells whether a Core has throttled since HWinfo has started, but it tells which Core(s) did it. If it is just one Hot core, that is one thing, if it is all 4 then that is something else.

I set Snipping Tool up so I can click the "New" button at the exact second, 10 sec before the end, and 5 seconds before the end of the XTU tests above, so I can show right at the end of the run what transpired. It isn't hard to do, you need to resize HWinfo and scroll it so it shows the right info, see my examples above.

So far your first test, Cinebench, was fine, these XTU runs are too hot and throttling isn't good.

Did you run the XTU test on any of your other attempts at getting a good laptop?

>>>> I wonder what it means when the range says 0 c to 97?

Without a snapshot of the state of the test results I can't tell what you are asking 🙂

ran it again, and max temp=98 c, max throttle: 37% (again at stock settings)

Seems like video card is fine (what are the normal scores?) but processor is dangerously close to that 100 c mark <---this is what worries me

The system/CPU is protecting itself from overheating by Thermal Throttling, so there isn't any danger of damaging the CPU. Just don't turn off thermal throttling or other thermal protections 🙂

Your temps during the XTU stress test, and other such tests, are going to push the limits of the system cooling, and you would expect at some thermal ambient (room temperature) you would see thermal throttling, so it isn't necessarily a bad thing. It is disappointing.

The temps during the Cinebench and 3dmark runs look like mine.

I ran the XTU 5 minute stress test at my normal settings with max OC and -60mv, and I didn't get thermal throttling. I am about to do a run at stock CPU settings with no negative voltage offset and I will post both results.

If you aren't going to be running your laptop at 100% CPU all the time, so you should never hit thermal throttling in every day use. And, you can still use XTU to set negative voltage offset at stock settings and reduce the heat output - which will reduce the instance/duration of thermal throttling you are seeing when running XTU stress test.

Darnassus, you have BestBuy in Australia too?
