From the previous review on Hexus www.hexus.net/content/item.php?item=5087I found that the earlier version (maybe the prototype?) of N5200 has VGA and audio connectors on board, but the N5200 I have got does not have these connectors. I was wondering if I can modify the unit and put the audio and VGA connectors on. I am not good at this, so I'll have to ask my friends who knows what to do to modify the N5200. Will post the result here when it is done, anyone interested in this modification? |

I haven't looked at the board very closely, but I'm guessing the prototype was some standard ITX form factor motherboard whereas the current version is a custom job minus some components (VGA connector, sound connectors, mouse/keyboard, and probably the chips for all, assuming the motherboard chipset can't do video) to save cost. Best case (assuming the chips are still there), you'd be looking at soldiering the vga connector and plugs for sound. I did notice that the back panel has knock-outs for sound, ps/2 keyboard/mouse, and vga... at least that wouldn't need to be modified.  |

It works, I can see the see the BIOS screen from the VGA port now. I don't have a digital camera on hand to show the pictures, but it really works.
I am checking other things on the MB right now. I think the PS/2 might work, but the audio may not, because there's no audio codec on board.
I'll check if there's anything else I can find. ;D

Hehehe, I found something VERY interesting.
There are two jumpers on the MB of N5200, one is marked as CCMOS, so it is quiet sure what it is about, the other is marked as JP1, dunno what it is for.
I set the JP1 from pin 1-2 to pin 2-3, and run the system for several days. At first I did not notice any differences, but when I turned off the system one day and turned it on again, I saw the BIOS screen shows it is running at 800MHz, not 600MHz.
I changed the jumper again to make sure if it is because of the jumper, and made sure that the jumper is the front side bus switch. The original setting is 100MHz, pin 2-3 is 133MHz, so the CPU is overclocked from 600MHz to 800MHz.
I am not sure if this will cause any harm to the system, so if you are going to do it, do it at your own risk ;D.

Good find! I wonder if it offers any performance improvements (especially with extra RAM).
I'm still not adventurous enough to try and hook up a vga port myself though.

Yes, there is some performance gain after the system is overclocked. I did some test, although it is not accurate, it shows that the performance gain is about 10% to 20%. I think the processor can handle the overclocking quiet well, there is not any sign of overheating or other problems. You can just try to switch the jumper if you would like to try overclocking the system, no need to hook up the VGA port. Original frequency  Overclocked  |

Hi ltj! how did you manage to access the vga port at your N5200? Did you have to solder a connector to some pins? Would be very nice if you could share with us what you did to get the vga output!
