Overclocks

• SetFSB: Clock Generator (PLL) is ICS9LPRS365BGLF. Source here. Confirmation here.
• Credit to lee_what2004 at forum dot lowyat dot net:-
  

  The PLL isn't supported fully by SetFSB for the A42Jv I tested, you need to edit the registry
  You need to change yours in these 3 circles into that number...
  user posted image
  
  and if want to change the BCLK,
  to increase ~7MHz, decrease the 97 to 96
  to increase ~3MHz, decrease the 39 to 38...

Hi, how is the webcam on this thing? It says its 0.3 mega pixels which seems awfully low.

Yes, it is low. I'm not using it much except for face-recognition login feature. This is one thing I never pay attention much when buying notebook computer. It work on YM video conference. People on the other side can see me, so it is ok for me. Not that I want to use it for recording or anything.

Yes but you're selling it already. I think most people (for gaming & multimedia) will go with N or G series when buying Asus notebook. Actually there are not much of difference between all Asus notebook series. Of course G series will have mid to high-stream graphic card & U series will have optional 8 cell battery. The lack of e-sata, firewire & express card slot on this notebook prevent people from buying this laptop. I will not bought this notebook if this is my first new notebook. I already have entertainment notebook, Dell Studio 1557, with all features I want. I bought it earlier this year. It only lack of games performances. I can play demanding games on it, thanks to GDDR3, but on some games I need to lower down the settings for me to play "comfortably". This is where Asus K42JV notebook come in. It have Nvidia GT335M which is a mid-stream graphic card, which is the only reason why I bought it. Also, I like the design very much. I don't want to buy G series notebook because it will only make my Dell Studio seems too outdated (or useless). You see my dilemma here.

I'm only half heartedly selling it.

I actually haven't had any issues with it. Screen is slightly above par. The GPU plays any game I've thrown at it. Speakers are okay, not great, but they're loud enough to watch a movie with VLC boost. Battery life is not great. Not because of the 6 cells, but because of the 4400mah.

My biggest issue is I wish I'd kept the A42JV that came with 2GB free. It's not bad, but the A42JV is slicker looking IMO. I thought the A42 had a charging problem, but neither I nor the Thai salesmen knew that the battery won't charge unless it's less than 95% full. They didn't have any more A42 in stock, which lead to the K42 which didn't come with the extra 2GB, and is less slick looking.

I didn't know that. Do Asus supply 6 cell battery with better capacity for this notebook? Can we use 3rd party battery? Instead 4400mah, what is the right capacity for 6 cell battery? There are shops who provide battery customization service but I don't know which brand is good.

Mine is A42JV but the motherboard (and everything else) is actually labeled as K42JV. No problem since both actually the same. About the battery, do you think the behavior is to prolonged the battery life? Does your battery decrease from 100% to 95% (maybe slowly - 99%, 98%, 97%, etc) while the notebook using external power supply?

BTW, I have USB Microsoft LifeChat LX-3000 headphone I bought two years ago & I haven't use it for a long time. It still work & perfect with this notebook if I want to chat while playing games (especially Life 4 Dead 2 ). But my SonicGear HP800 headphone (jack) produced better audio. It will be perfect when watching movies.

sawat dee,

Yes, I don't even know why they made the K42 case. The A42 case looks much better IMO. They don't sell the A42 case in America (I got mine at Panthip BKK) which I think was a big mistake. It would of been more popular otherwise.


There exists 6 cell 6600mah batteries, but I don't think they make them for our laptops

It's strange because the battery in the Acer 4820TG lasts 5 hours with light use and integrated graphics and that is 4400mah also... But that was the i3 model. I don't know about 4820TG i5.

Either Asus is giving us a cheap battery or Acer is using very high quality batteries, or our notebook just uses more power to run it.

Yes, that happens with batteries even if you're not using it, it will slowly lose it's charge. Like 1% or so every day or 2. Something like that.

[lee_what2004]

No, the 4820TG is using 6000mAh battery for 6 cell .and 9000mAh for 9cell...

Hi guys,

Today I have time to overclock Bus Speed with SetFSB. Windows freezed one time when I tried to overclock it too much (address 0xF = D5). No biggie. I believe I can achieve 3GHz on this machine.

Overclock Bus Speed with SetFSB
Bus Speed = 133MHz (Default)

Bus Speed = 145.1MHz

Bus Speed = 148MHz
