China Industrial PC performance

Hi guys,

I'm developing a program for a kiosk that was come with IPC from China that comes with Windows 8 Pro. Currently I'm facing a problem where my program will crash at least once for 12hours running.

Before this project, I never had this problem when using Intel NUC and self-assemble IPC using branded manufacturer such as Asus/MSi from local suppliers with Windows Embedded Standard 7 for past 5 projects.

So, is anyone have some experience or information regarding China IPC performance and compatibility to share? I already minimize the performance of the program and keep low image quality and some other performance tips gather from internet for past 8months but still no solutions on this.

IPC Spec:-
Intel i5 3.2GHz
4GB DDR3
DirectX
Windows 8 x64

Platform:-
.NET4 and WPF

Local Database:-
MySQL v5.5

Screen Resolution:-
1920x1080

How to buy a good speaker

liey87 — Fri, 16 Aug 2013 19:51:54 +0800

Hi all,

Sorry if I don't enter the thread..I'm new here.

To all speaker expert, could you help me to describe how to count whether the speaker is good or not?
I have seen the specification of the speaker and most of it, I don't know what it is about

As example:

Speaker power:
5.5 Watts RMS per channel (2 channels)
16 Watts RMS subwoofer

Frequency response:
40Hz ~ 20kHz

SNR :
>75dB

Tweeter:
33 Watts per Channel @ 4 ohms @ 10% THD @ 2.5 kHz – 20 kHz

Subwoofer:
68 Watts @ 8 ohms @ 10 % THD @ 40 Hz – 180 Hz Single Channel Loaded

System Response:
40 Hz – 20 kHz (-10 dB)

Sound pressure level (SPL):
106 dB

What should I consider from the spec before buy? A little help to me might help others a lot
