Yeah, unless you know where to go. There's only 1 place I can recommend there now. It's called Restaurant Malaysia, located opposite the police station.

Finally after updating my driver.... the Optimus is working back to normal. Getting Ultra settings + Smooth game

^ All games?

Nope, I only tried in Flight Simulator X and Hot Pursuit
Soon to figure out GTAIV & Crysis 2

Guys, i discovered something strange. Can u guys N45sf or N55sf users run some test?

First, guys go and get batterycare. Install it, double click on the icon and detailed information. U can see charging and discharge rate.

Secondly, plug in ur battery and pull out your adapter. Note the discharge rate and post it here pls.(if ur battery is 100%, discharge it a bit by playing games or something heavy, coz we wanna see the net wattage here)

Thirdly, plug in ur adapter(battery still in there). Then open up MSI afterburner and furmark test. Start the burn in test. At the beginning of the test the gpu should still be able to run at default speed for some times.(NOTE the charge/discharge rate also, and post it here). Then after a few second maybe the gpu will start to underclock and spiking(note the charge/discharge rate also, and post it here).

And i encounter one problem here. When i started the furmark test with adapter and battery, when the graph is still running at default speed, i hear a high pitch 'yeee yeee yeee' sound from my laptop. Then after some time, when the gpu starts spiking, the sound is gone.

Guys, pls run this test and let us know the result can?

C/D rate(battery): -23.3

C/D rate(adapter+battery and running furmark, gpu still at default clock): +2.3

C/D rate(adapter+battery and running furmark, gpu starts spiking): +23.3

Guys can u pls run this test? No matter N45sf or N55sf. We would like to compare. And pls tell us whether u hear the same high pitch 'yee yee yee' sound. This sound can be some physical circuit problem or some power issue. Pls do help us. Coz this may lead to solving N45SF's throttling problem.

u getting smooth game ultra settings in crysis 2 with driver 280.26?

pls run the test for us man. Wanna clarify something

Okok, will do it asap and post the results here

I did this test on my Lenovo G470 (not relevant, but might help)
I got my results as such :
C/D rate (battery):-20.4

C/D rate (adapter + battery): +24.2

C/D rate (adapter + battery + CS:S (using Intel HD3000, nothing much to test)): +10.3

No idea about the sound though =\

@htpkevin, if you run furmark without battery, only power adaptor, less spike ?

ya it seems slightly better a bit. The spikes have longer plataeu. But only very little

C/D rate(battery): -22.2

C/D rate(adapter+battery and running furmark, gpu still at default clock): +2.1

C/D rate(adapter+battery and running furmark, gpu starts spiking): +23.1

i also heard the yee yee sound..quite loud de....

ok. So u are same too. Ok, now we need to ask other member to do this also, no matter n55sf or n45sf. This can contribute to our n45sf problem

Hmm...so far only the N45 users tested this yes?
Aiya....one after another.

Try performing the test that bro htpkevin did.

great, just the 3rd day after reformat and here it goes again, sudden reboot out of nowhere... but looks much better as this time, it switches off suddenly and reboots on its own, previously is just OFF totally off...

Hi friends , i am from Auckland ,New Zealand .Last month i ordered on of the Asus N55Sf-1037v . i was looking at your forum for the price comparison and it seems there are lots of variants for the N55 model . as i can see the one i ordered is totally different config from the all you got here . so can you please tell me what is costs in Malaysia for my below said config.
Asus N55Sf-1037V i5 2410M, 4GB Ram,750 GB HDD,2GB GT555 ,Blu Ray ODD,HD Camera ,Full 1080p Screen . and I paid 1400NZ$Thanks .
Any help will be highly appreciated friends .
Thanks a lot in advance

For 1400NZ$, you could easily get the i7 variant of the N55SF if you add a little extra more (and yes, all other specifications will be pretty much the same).

On a side note, I just got my hands on the N55SF i7 today and upon removing a vast majority of the "bloatwares" my ATK driver somehow stopped working - evident from the fact the multimedia buttons stopped working. It's also pretty strange how I got "4.8" for Graphics based on the Windows Experience Index :| Other than that, everything seems good so far. Quite doubtful about the unusual RAM usage too (but maybe it's just me) since it's averaging around 50% of 4GB. Perhaps I'll reformat it back to factory default settings and go from there as advised by the OP.

thanks a lot . but no use as i already paid for it as asus dont have a online shop as dell or hp in nz .

guys pls run this test. We really need to know. Or else N45SF can never be fixed

Updating ur graphic card driver will change ur Windows Experience Index from 4.8 to 5.9.Plus it fixes the optimus.
