When you upgrade from windows 8 to windows 8.1 it is actually a complete windows update equivalent to going from windows 7 to windows 8.
In doing so it blasts away a number of your settings that you may not have thought of.
When I installed my Samsung 830 SSD in my laptop I used Samsung magician to optimise and change the settings that are not required with SSD drives.
I did things like:
- Disabled Pre-fetch and super-fetch
- Turned off scheduled defrag
- adjusted my pagefile down to certain limit
- turn off write-cache buffer flushing
After windows 8.1 is installed all of these settings are lost. I found out much to my surprise as a defrag had been executed on my machine.
Here are a few articles that talk about all the possible optimisations, the first is from microsoft;
Windows 7 & SSD: defragmentation, SuperFetch, prefetch

Recently I upgraded my HP Pavilion dv6 laptop to windows 8. Windows 8 detected and installed the default Intel HD video driver only. The switchable graphics driver was not installed. The ATI HD5650 was not being used.
The following instructions are what I did to successfully install the switchable graphics driver on Windows 8 Pro 64-Bit
1. Download the driver for your HP Pavilion model. My driver was for example here:
2. Run the downloaded driver.
- Click Next
- Accept the terms and click next
- The default location will be something like “c:\swsetup\SP50640” click next.
(I will refer to this directory through the following steps, just use your specific directory)
- The software will extract to that location
- When the driver installation starts click cancel
3. Install the C++ redistributable
- Enter the video driver directory e.g. “c:\swsetup\SP50640”
- Enter the C:\swsetup\SP50640\Packages\Apps\VC10RTx64\vcredist_x64 diretory (64-bit) or;
C:\swsetup\SP50640\Packages\Apps\VC10RTx86\vcredist_x86 for 32 bit
- Choose properties and set the compatibility to Windows 7.
- Run as administrator
- Follow the prompts and complete the install
4. Install the ATI Driver
- 64-Bit – enter the C:\swsetup\SP50640\Bin64 directory
- 32-bit – enter the C:\swsetup\SP50640\Bin directory
- Choose right-click properties on the “InstallManagerApp.exe”
- Set compatibility to run as “Windows 7”
- Choose Run as Administrator
The driver should be successfully installed. IWOMM
I have a HP Pavilion dv6 3030tx.
This is a Core i5-540M Notebook with 4GB of memory.
It is upgradeable to 8GB (2x4GB).
This computer is running Windows 7 – 64bit Home
I found some memory on eBay and purchased some Corsair CMSO8GX3M2A1333C9.
When this arrived I put them in the Notebook and the BIOS seemed to reference them saying 8GB on board but the PC would not boot and kept crashing about 5 seconds into loading windows.
I tried to run mem test and it would crash after about 3 seconds.
(Note: the eBay guy happily refunded the memory once I confirmed that they were incompatible. So I will give him a little plug, D & D Computers Online and their eBay store D & D International eBay Store
If you are in Australia, they were very understanding with my problem, so you can do much worse than buying from them.
End Plug now.)
The compatible memory for this computer is:
- CAS: 7-7-7-20
These specs all looked fine on the corsair memory above, apart from one thing…
The Intel HM55 southbridge chip set will only be able to use memory packaged with 256Mx8 memory modules
What does this mean?
To make 4GB of memory I could do it with 8 x 512MB memory chips or I could use 16 x 256MB chips.
(If you have a look at some memory photos you can see this as either 4 or 8 memory blocks on one side of the memory circuit board.)
The Intel HM55 chipset cannot use memory with 512Mx8 memory.
The Pavilion dv6 3030tx runs the HM55 intel chipset and hence you need to find memory with the specific 256Mx8 memory packaging.
Here are some links to the various forum posts that I used to get to this answer.
I have been running Crysis 2 on my DVI connection no worries, but recently I changed to a HDMI cable to connect my Benq E2420HD to my Msi R6850 video card.
If you see my previous post, Benq Monitor and HDMI not working you will see that I had some issues with getting my monitor to work, but I found the settings and all was good with the world.. until I launched Crysis 2.
When Crysis 2 runs with DX 11 in full screen mode, it runs @ 50Hz.
My monitor can handle 50Hz, (it is a supported refresh rate), but the game did not fill the full screen. The full screen was black but the edges of the game fell about 1cm short or the edge of my screen.
So WTF was going on?
Catalyst Control Centre.. again..
The issue is the overscan setting. As per the previous post (link above), I had to set the overscan setting to 0%. But when the monitor switches to 50Hz it also switches to a different profile, and this profile has the overscan setting to about the middle of this bar, (approx 7.5% underscan)
The solution is:
- Launch Catalyst control centre
- Expand “Desktop Management” and click on “Desktop Properties”
- Set the monitor to use 50Hz and click apply
your monitor will switch and wow you suddenly see the black border similar to when you were playing Crysis 2
- Switch to the “Scaling Options” and set the Overscan to 0% and click apply
When you play Crysis it will now fill the full screen.
Got to go.. stuff to shoot .. 😉
Attaching a monitor to a pc via HDMI should be easy… right.
Well on hooking up a Benq E2420HD monitor to a MSi R6850 (PM2DIGD5), the image looked terrible.
It took a bit of tweaking but these are the steps you will need to follow to get things looking how they should.
Step 1. Catalyst Control Centre Settings
In my case the software was defaulting to set the scaling options to “under scaled”! (about -7.5%)
Turn the scaling off and set it to 0% as shown.
Step 2. Monitor Settings
You need to turn off the overscan feature, in the monitors OSD (on-screen display) settings.
- Go to the Picture Advanced page and choose display mode
- Set the Overscan feature to OFF
Problem solved 🙂
