Hi,, it is Possible to OC A laptop Graphics Card. . I'm having a Dell Inspiron 15R (N5010)
Default config :
Intel Core i5-480M (2.666.7 Mhz ~ 2.6 Ghz)
Intel HM57 (IbexPeak-M DH) - MotherBoard
RAM : Samsung (M471B5773CHS-CH9) 4GB (2x2Gb) - 533.1 Mhz
ATI Mobility Radeon HD 550v (M96) - 1Gb - Core speed 450Mhz / Mem Speed - 600 Mhz
But I have Tweaked all most all the Hardware settings to current Config :
Intel Core i5-480M ~ 2.6 Ghz -> Now Turbo boosted to 2.9 Ghz
RAM : Samsung (M471B5773CHS-CH9) 4GB (2x2Gb) - 533.1 Mhz -> Reduces the Latency as much as possible with stability
ATI Mobility Radeon HD 550v (M96) - 1Gb - -> current speed Core speed 650Mhz / Mem Speed - 796.1 Mhz
And you wont blve it . . on the Default Config the Windows Assessment Score was 5.4 , , and After all the Tweakings its now 6.5 . .
k .. so Here's wht i Did..
1.) First For the Graphics Card:
1.) AMD Catalyst 12.2 Preview Driver
(http://downloads.guru3d.com/AMD-Catalys ... -2848.html
2.) RivaTuner, GPU-Z,
(available at 3dguru.com)
Install the AMD Catalyst 12.2 Preview Driver...
Install the "RivaTuner" but don't open the programm.
Now open the "GPU-Z" and watch the Device ID you have.
Go to C:\Program Files\RivaTuner v2.24
search the file RivaTuner.cfg and open with Notepad.
search "[GPU_1002]". you will see ATI chipset numbers and IDs.
For ATI Mobility Radeon HD4570 search RV710 and add the Device ID + h. something like this ( ,XXXXh)
For ATI Mobility Radeon HD4650/HD4670 search RV730 and add the Device ID + h. something like this ( ,XXXXh)
Now save the file on Desktop RivaTuner.cfg
Remove the RivaTuner.cfg from the Rivatuner folder and then paste the new file from your Desktop to the RivaTuner folder
Lunch the Rivatuner.exe
Now you can see you videocard in the window
Click on it and choose the videocard picture
Now click on "Enable low-lavel hardware overclocking"
I recommend for ATI Mobility Radeon 4650 HD: Core clock=650MHz / Memory clock=796MHz for stability of your system
Now click on "Apply overclocking at Windows stratup"
Click on "Restore clock frequencies after suspended mode"
Click "Apply" then "Ok"
Go to "GPU-Z" and watch your Core clock&Memory clock.
And for higher Performance ... Tweak the RAM timings :
1.) CPUTweaker v 1.5
Extract the CPUtweaker folder,,
Open Cpu Tweaker
and change the timings carefully...
According to my RAM i gve these values :
-> RAM Timmings I modified using CPU-Tweaker 1.5 (Dell Inspiron 15R N5010)
trcd-r - 6
trp - 5
tras - 8
Sub timmings Down :
trfc - 64
trrd - 1
Twtp - 13
tref - 2080T
All Precharge to Active - 6
All Precharge to Refresh -6
Precharge to Precharge D - 0
Refresh to Refresh D - 64
Trd - 6
mch ODT Read Command - 0
Dram ODT Write Command - 0
Dram ODT Read Command - 0
After this click on Apply . . .
NOTE: I 'm having one problem in this tht is,,, CPUTweaker is not setting my defined timings at window Startup.. i have to apply these time manually every time window starts up . . rest,,, my system is working absolutely fine...
And the last Tweak,, I enabled Intel SpeedStep from the BIOS,, and Installed the Intel TurboBoost Driver.
and then went to the advanced power Options and changed the 'Min Processor State' under the ' Processor Power Management' to 100% for Plugged In mode
and changed the ' Max Processor State ' under the same menu to 99% to both Battery and Plugged In modes...
That is it.... then my Windows Assignmet Score went up from 5.4 to a whooping 6.5 . .
For further Benching I have used 4 Games to keep an eye on the Performance, Lagging, and FPS:
# All games have been tested at Default Graphics Settings of the Games, , Only the Resolution was Max i.e 1366x768
Games Used _________________ Initial FPS ___________ Tweaked Settings FPS
FEAR 3 78 126
NFS Hot Pursuit 2011 58 93
SSF4 AE 65 96
Battle Field 3 (2011) 39 69
So.. Iguess... changing the Graphics options for individual games will even give a much more high FPS . .
Hope u Like my Post..
