CPU Overclocking -
GPU Overclocking.
GPU:
Furmark
Hwinfo
GPU-z
For GPU overclocking you want: ATI Overdrive (recommended), ATI Clock Tool or Afterburner also work from what I have used in the past. ATI overdrive accessed through the CCC facility has a clever facility to check for artifacts and makes sure that clock is stable enough to prevent them and then you can stress test it using Furmark and if it does not lock up/glitch/artifact after around 5-10 minutes you should be ok using those clocks. Overclocking is also dependent on the software as well some programs/games can still crash or cause the display driver to crash when overclocking.
I use 825/1100 but can handle 840/1135. Good to test and find what is stable and works best for you. Above 825/1100 I notice flickering in some games so I stick with what I have apart from when benchmarking.
CPU:
SETFsb CPU Overclocking using a G73JH 720QM
SetFSB
Timing Fix
Timing Tester
With SETFSB you simply raise the PLL and test every couple of mhz by using something like Prime 95 to make sure it does not lock up or BSOD. If you have the 720qm like me you will start at 139PLL or 153PLL depending if you have turbo mode on. Work your way up and as above you will gradually reach a point where things start not responding, gadgets and programs start crashing and you eventually BSOD. For me that is around 187PLL although my overclock ability as per my sig link of 2ghz is a lot higher than the norm and I usually hang around 185PLL to remain stable. Remember what your highest clock is and drop it down 4 or 5mhz once you have rebooted from the BSOD and then stress and test the PLL to make sure its stable, if not drop it a few more.
(SETFSB will reset back to default 139PLL if you crash or restart your computer)
IMPORTANT: have a read through
this and apply this fix if you plan to o/c the CPU as Windows 7 has an adverse effect which needs correcting with a simple timing fix applied through DOS prompt using administrator settings. All compliments go to Unclewebb for this fix and his continued support with CPU overclocking.
Overclocks are limited by voltage and thanks to Asus it would appear because of hardwiring the G73JH cannot be changed so as long as you have good temps at the moment or good paste you wont really need to worry about the small increase in temperature, but use HWINFO to make sure everything is running as it should by using the sensors. Also every chip is different so do not expect to reach what others have or expect to reach more, as Tijo has explained on another recent overclocking post that chips are put through certain tests to make sure they can handle the stock clocks, voltage, watts, etc (called binning) and if they pass the tests they are allowed into the OEM production world, they do not necessarily test for the chip to reach the sort of output we aim for which in my case is excessive and im nearing the point of attaching a car battery to the GPU/CPU.
-------------------------------
You shouldn't have any problems if you stick to the basics all of the information above covers the majority of questions involved in overclocking and it is straight forward. Use HWINFO sensors when overclocking and testing to keep an eye on the temps, with this type of overclocking you shouldn't see any major problems but stress test with Furmark at stock to see what your maximum temps are to begin with. If you are already hitting 95oC or above on any section of the GPU you would do best to clean out your fan vents with compressed air or consider repasting before attempting to overclock.
Important: If you do not have Overdrive in your CCC then you will need to flash the latest Vbios first .93V from Chastity Driver Reference.
As always if you are still not confident after watching and reading all of this then don't attempt it because the majority of serious problems result when someone does not know what they are doing, with overclocking the problems are normally minor (BSOD, locking up, crashing) but anything you do is at your own risk. If it is not broken dont try and fix it, with overclocking only attempt it if you really need it and the majority of the time its just an added extra for most.
Any questions PM me.
Problems? See this thread at archive.org.
do i still have to buy the utility to get my laptop working at proper speeds ..thanks ..
