Asus N71JA/X77JA review by OC-Freak

[OC-Freak]

While all the fuzz is around the Asus G73JH, those looking at less expensive all-round PC might be interested in reading this review.

I originally did an quick review here: Asus N71JA/X77JA first impressions/mini review. But doing an new writeup here to include more test results. My first was DOA (I suspect that antennas for the wireless card was not properly connected), but the new one appears to work perfectly fine.

My computer is an X77JA which is actually an N71JA, but with no extras (no bag/mouse).

Specs:
17,3" 1600x900 LED backlit LCD. (manufactured by LG)
Core i5-430M 2,26GHz
ATI Radeon HD5730 1Gb DDR3 (650MHz core / 800MHz memory)
500Gb 5400rpm HDD (Seagate momentus ST9500325AS)
Super multi DVD-drive (LG GT30N)
4GB DDR3 1066MHz (Actually it's 1333MHz kingston memory)
Atheros N-wireless
USB 3.0
4400mAh 6 cell battery.

Images:
I do not have an good camera, so refer to this link for images - it looks identical to my laptop.

CPU-Z:



First impressions:
The keyboard is very good, best I've had on an laptop, but it's not very silent to type on, you can hear the key clicking quite well.
The trackpad is good, but reqires getting used to, I'm used to scroll by dragging along bottom or right edge, but I've found no option to enable that with this elantech pad. Instead it uses two fingers scrolling..... which requires getting used too
The LG monitor is average, it looks crisp, but viewing angles are average like most TN panels. Better than my old Acer 5930G laptop, but not as good as the monitor on my old Asus M50SA (had an great monitor from AUO optronics).
The laptop build quality feels good, it's quite light for an 17", keyboard doesn't flex, and pushing at the back of the monitor doesn't give image distortions.

Speakers:
The laptop has altec lansing speakers + subwoofer, and the sound is great, you might have to use the sound control panel to adjust it to your liking, but after doing so the sound is great, with noticeable bass, and acceptable volume. But don't expect to get blown away, it's an laptop afer all

Noise:
The computer is very silent during normal use, but uses "spin up fan for short time when needed" rather than "always spin fan at very low speed" which I prefer.
During load the fan is noticeable as an blowing sound, but not very loud, and not with annoying whining or whirring sounds.
Overall quite pleased.

Performance:
First up the standard windows rating, which honestly don't say

Vantage performance test (connected an external monitor to be able to run default test):


Crysis demo @ high quality and 1280 x 720 resolution (1600 x 900 not selectable)



Battery life:

Settings: Balanced profile, 70% brightness, profile modified to not dim monitor or turn off monitor, as well as keeping the computer on until there is 1% battery left.

Using battery eaters reading test to simulate light usage.

Temperatures:
This is the real stress test, running prime 95 and Furmark max burning at same time. Since GPU and CPU share the same cooling solution running separate tests is almost pointless.

Also notice that reaching these temps under normal use is very unlikely. Throttling treshold for the core i5-430 seems to be 105 degrees celsius.




CPU peaking out at 94 C and GPU peaking out at 81 C. Even with these temps the computer only feels slightly varm to the touch, my old acer 5930G gets uncomfortably hot to type on during similar stress testing.

Also there was no throttling during the testing.

Summary:
Positive:
Build quality and design.
Weight.
Performance/price ratio.
USB 3.0
Silent during use.
Great keyboard
Great speakers
1600 x 900 resolution fits the screen quite well. Full HD would be nice but more straining on eyes (at least for me).
Doesn't get hot to the touch even during heavy load.
Very silent DVD-Drive.

Negative:
Average bettery, had preferred an larger battery for an 17" PC.
Doesn't support switching to the core i5-430 intel GMA gfx to save battery.
2nd Harddrive bay can't be used to add an 2nd harddrive since it lacks connectors/cables.

Overall I'm very happy with the computer.

The ATI HD5730 is based on the desktop "Redwood" HD5670 hardware. It's clocked at 650MHz and equipped with 1GB of DDR3 memory clocked at 800MHz, just like ATI specs. While I do not expect a lot of overclocking headroom, it's always fun to try. Using the latest AMD GPU tool to overclock the card.

Using 3dmark06 1280 x 768 and default vantage performance test.

700MHz core and 850MHz memory:




No issues found and it responded quite nice to the overclock and numbers increased more than I had expected. Let's go for more!

750MHz core and 900MHz memory:




Another noticeable bump in score, ready for more?

800MHz core and 950MHz memory:




Another bump in scores, more than 1000 points extra in 3dmark06 compared to stock speed. Do this card have any limits? Let's see!

850Mhz core and 1000MHz memory:




That is quite impressive! 200MHz extra for both core and memory! But no it's not stable, it's perfectly fine for benchmarking and probably most gaming but it's not stress testing stable, when using furmark it will crash sooner or later (Dispaly driver stopped responding and has been restarted error message).

I found the sweet spot to be 800MHz core and 1000MHz memory, that is + 150MHz for the core and +200MHz for the memory. Very impressive and a lot more than I expected.

Crysis demo at 800/1000MHz:



Temps at 800/1000MHz (furmark extreme burning + prime95 max temp at same time):




The GPU peaks out at 85 C now and the added heat to the cooling solution makes the Core i5 peak out at 97 C.

The overclocking potential of the GPU surprised me, was expecting to get +50MHz on core/memory or so, not more. For everyday use I won't use the overclocking potential, but for gaming I might occasionally use it.

The 5730 is 10-15% faster than the 5650 based on your scores. These new Radeons are pretty good.

2nd Harddrive bay can't be used to add an 2nd harddrive since it lacks connectors/cables.

This is strange, so it has a space for a second HDD but you can't put one in?

It's sold with either one or two harddrives (different models coming pre-configured from asus), but the one with only one harddrive like mine doesn't have connectors for the harddrive in the 2nd slot. Asus saving cost I guess.

OC-Freak how are you getting the temps off the GPU?

[OC-Freak]

Latest version of furmark supports reading the temp, or you might use AMD GPU tool. Click the thermal sensors tab, click the upper sensor (ASIC Temperature via internal TSS 0) check enable reading, and then click start to monitor the temps.

Like I did on the attached image.

I have found no other programs that supports temp readings from these cards yet.

[OC-Freak]

Image of the 2nd harddrive bay with no connectors, and image of the very funky looking subwoofer.

Also tip about sound; I found it better to disable "SRS Premium sound", it fits my listening taste a lot better at least. None of the presets were as good as having it disabled.

[Adamal]

Thanks that worked.

I was using Everest Ultimate for temps yesterday and it seemed to be reading the GPU sensor...had a listing for it and gave a reading.
