Hi guys,

I have an inspiron 1545 with a hd 4330 with 256 mb gddr3 VRAM.

I tried to extract the bios but GPU-Z said bios reading not supported i

heard somewhere that pc manufacturers cuts of the read/write pins of

the GPU

Some gu ys told me that in some laptops the Video BIOS is a part of the

main

bios. If it is true what if I extract the video bios from my main bios

setup file &

after changing the clock speed reflash the main bios.By the way my bios

version is A14

Overclocking a laptop such as this usually isn't worth the effort.

That aside, the GPU is not a high end GPU, and has enough memory to run

the usual non game applications, and some less demanding games, or games

at lower video resolution.



The general run of laptops have mfr specific BIOS, possibly drivers, and

sometimes mfr unique hardware. This makes many possible mods difficult

to impossible.
 
hi chuck,

what you are saying is true.The bios and the multipliers are

hard locked But when i was using vista i somehow managed to find the PLL

an increase the FSB from 800 MHz to 850 MHz using clockgen & it was

stable.I know that wasn't an achievement but then i had my exams and

after it i forgot about the overclock and i reformatted my hdd &

installed windows 7.When i tried GTA 4 And ran benchmarking i got the

average FPS as 31.48 The setting:



Resolution: 1204 x 768

Shadows: Off



This is actually high for this laptop but need to overclock it badly i

dont even care frying the mobo. Currently my gpu is overclocked from 450

MHz Core to 550 Mhz & the maximum temps are 68 degrees when i played gta

4 non stop for 4-5 hours. Actually my dad told me to get a quad core but

i though this laotop was enough i think i am an idio So if i want to

upgrade can i atleast upgrade to processor to somthing like the t9000

series

Laptops generally have the CPU installed rather permanently (Soldered Ball

Grid Array)
