Acer Aspire 5740G Owners Lounge

Originally mk1freak suggested that I started Owners Lounge for this model.

I've been a bit hesitant (read: lazy) but now I see there are at least several threads concerning graphics, Bluetooth, performance, BIOS updates etc and it's getting difficult to follow them all. Additionally good information is scattered in different threads, so I finally decided to start this thread.



So as not to leave the first post with "hello" only I prepared some screens of tests and benchmarks. This thread is going to be updated by me and hopefully other owners (mk1freak is kinda forced to help as it's been his idea in the first place)

If you got any requests for benchmarks or questions go ahead.

I will answer those if I can- I don't own all the games in the world so demos with benchmarks are preferred



First of all my config:

Acer Aspire 5740G-434G50Mn

434G50Mn means:

43 stands for Core i5 430 2.27GHz 3MB cache

4G stands for 4GB DDR3 1066MHz (mine made by Samsung)

50 stands for 500GB 5400 rpm drive (Hitachi in my case)

M stands for Multi drive- meaning DVD-R/RW/RAM (TSST TS-L633C)

n stands for Draft N Wi-Fi card (whereas "i" stands for 802.11g)



The rest of relevant specs:

Mobility Radeon HD5650 1GB DDR3 (core 550MHz, memory 750MHz)

15,6" 16:9 LED backlit, 1366x768 LCD (mine is AU Optronics AUO22EC)

6 cell Li-ion battery, 4400mAh

Wi-Fi Card Atheros AR5B93 (two antennas but capable of 300mbit/s)

LAN card 10/100/1000 Broadcom NetLink BCM57780

Realtek HD Audio ALC272



That is all running on Windows 7 Home Premium 64bit



GPU overclocking

Mobility Radeon HD5650 is the same exact card as HD5730- the only difference is that 5730 is factory overclocked. As this card has very low TDP and 5740G has good cooling system overclocking is something you must do if you play games.

AMD GPU clock Tools is used for that (from version



Prime95 stress test temperatures





When CPU reaches 80*C fan kicks in at "panic" speed so there is no way it gets any hotter.

Interesting matter is that Turbo Boost doesn't work like it should in this laptop. It actually works better

If I'm not mistaken Turbo Boost should work only when one core of the CPU is under load, so when there are four separate threads in Priime95 and CPU is maxed out on all cores and threads CPU should run @2.27GHz.

For some reason mine run at 2.46GHz most of the time. Not that I'm complaining...



HDD Benchmark

HD Tune 4.01

Average speed: 63,3MB/s

Good speed especially for a 5400rpm drive.







Battery test



Real life

Tests performed eith power saving profile and LCD at the lowest brightness (it's still enough though)

Notebook lasted some 3h 30min while browsing via Wi-Fi.

Nothing really intensive just the usuall morning routine- websites, forum, e-mail and so on. Something got downloaded, something else got updated but no hard tasks, no flash videos etc.



Battery Eater Readers Tests

Same settings as above, WiFi on.
