I have question, about Graphics Driver,
I had download driver at amd site for my 4820TG:
http://support.amd.com/us/gpudownload/wind...ob_win7-64.aspx

I run installer, says that ati/amd gpu not detected, so I restart and change to "Discrete" mode, and run installer again, seem graphics driver installer can install, but I think:

what if in discrete mode, I install latest ati/amd driver, then I change back to "Switchable" it will effect/problem?

As My previous question. Use latest official ATI/AMD driver on Timeline 4820TG. So I did!

First I go to BIOS, change [Switchable] to [Discreet]
Download and Install Catalyst Version: 12.3
Once Install complete, with no error, restart and change back to [Discreet] to [Switchable]

See:



Intel GPU use previous driver where ATi/AMD GPU use latest driver



About performance, based on Windows Experience Index,
[Switchable] "Graphics: 4.5" "Gaming Graphics: 6.1" (High performance GPU mode)
[Discreet] "Graphics: 6.7" "Gaming Graphics: 6.7"

About Intel driver, I think it use previous driver where I use Acer packaging Catalyst, mean need to install Acer packaging Catalyst version 8.84.7.4, then install latest official ATI/AMD driver in [Discreet] mode as mentions above.

I also have that problem, suddenly game slow (fps bit drop) and speaker come cracking sound = =
After restart, now Won't start, stuck at Windows Logo boot, with HDD LED always on = =
my hard disk: Western Digital

very annoying, I play BF3 online it very disturbing when fps drop + cracking sound.
before I run mod, I check WD Hard disk, my HDD now in Caution mode:


So I just ignore = =... run/edit HDD APM to "EFh/255" by use quiteHDD, and I try solve bit, but still have.

Some one also say, disable "PowerPlay™". By logic, "PowerPlay™" completely useless because "Switchable Graphics" take place:


I didn't test yet off "PowerPlay™"... later I come with result = =

My laptop warranty just last 19/March expired and come disk health: caution = =

I play game sure remove battery (unlike 4830TG)
why need enable PowerPlay? since Switchable Graphics take over?
Just last night I test play BF3 with disable PowerPlay, it improve performance, less drop fps..

I follow, except Enable PowerPlay = =

not green still yellow, =(
I had make topic: http://forum.lowyat.net/index.php?showtopic=2291417 you can see I run Extended Test, come error: Too many bad sector,
I have back up all file, now that bad sector can be fix by LLF/Zero-Fill format?

Full Format?
some advice me that run Write Zero and do partition and format

I download from WD and burn in CD, currently AHCI not detect, so I change IDE.
Now I running "Write Zero" then create partition as-usual. change back to AHCI, and install windows.


dose my step correct?

After doing "Write Zero" and Install Windows 7 then Updates, I feel much faster then previous format without "Write Zero", I use Windows 7 Professional SP1 from MSDNAA, now my hard disk back to normal

Talk about Flash HDD firmware, I think I try find seem impossible.

You have idea, what ever I play game, Steam or Origin, it sure have cracking sound middle playing, it very disturbing,

Pirate? nah... I buy damn game, so original, it should no problem,
BF3 quite happening when play, sound disappear then cracking happen...

use Windows default driver, make BF3 no sound, = = I try before, play game no sound.

some games no sound, play video music ok, but FLStudio (with ASIO 12ms latency) on Windows Default driver show very crap, some time play without ASIO4ALL clicking sound come, even audio latency in highest setting

you can see my post: http://forum.lowyat.net/index.php?showtopi...post&p=49866316 and it's work fine~



there any oc tool? i want increase bandwidth, I play BF3 quite slow = =
and GPU-Z view seen something go problem

what setting you use? it is AUTO?

well, seem same as me, need setting low can play smooth a bit = =
maybe 12GB/s bandwidth? can overclock?

only me or anyone notice that, when running in battery mode (Intel GPU) screen contrast changing,

by the way ngkhanmein, you know how to make permenent setting for Intel Graphics, everytime change GPU, it's keep change to default, which enable display power saving that changing Display Contrast

Most 3rd party converter report that Intel GPU rather then AMD GPU.

I just reformat to Ubuntu then change back to Windows, using Acer provided GPU driver,

I just realize that I play game (default setting) consistent 60fps!


I think update driver via AMD official might having issue since AMD not provide Switchable GPU, feel stick with default driver
(seem Ubuntu patch hardware?)
