CGI Proxy

What are CGI Proxies ?

It is a way to hide your IP address by communicating through a 3rd party server

Simple Analogy:
A wants to talk to C but D is looking at him.
So to ensure D doesn't know A uses Proxy B.
Whatever A wants to tell C, he tells B to pass the message to C
so D will not know A is actually communicating with C.

I added a new gadget on this site for CGI Proxy Testing (To test if the Proxy actually hides your IP)
Here is a site containing CGI Proxy Locations.
If you still want to find more simply google CGI Proxy.
Some CGI Proxies are actually fake, meaning other then advertising they don't proxy your IP addresses.
So to test whether they work simply enter my blog URL and look at the gadget.
If it displays your ISP and Dynamic IP address assigned by your ISP, it is a fake proxy hence don't use it.

Internet Explorer Tweak

Here is a registry tweak for Internet Explorer


Similar to the Mozilla Firefox tweak this enable you to increase the number simultaneous server connections.
It is one of the few "tweaks" Internet Explorer has as it is not designed to be this tweakable

If you can't see the words on the picture, the registry entry is as follows:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
Entries to be edited

"MaxConnectionsPerServer"

The Physical Memory Limits of Windows Vista/Xp 32bits

Clarification

There is no support for a full 4GB of Memory in Windows according to Mark Russinovich's Blog
After some research a simple explanation is that although originally PAE (Physical Addressing Extensions) was implemented to support more than 4GB of Memory Address, due to poor driver programming by vendors has resulted in Microsoft's convenient decision to simply pull the plug on PAE support in Client OS.
Their rationale being they couldn't resolve crashes on Windows 32bit Client Machines due to poorly programmed device drivers like WebCam etc.
However, this is not to say you cannot enable PAE on any 32bit Windows Operating System.
However it is not ANY Windows Operating System

Physical Memory Limits: Windows Server 2008

The following table specifies the limits on physical memory for Windows Server 2008. Limits greater than 4 GB for 32-bit Windows assume that PAE is enabled.
VersionLimit in 32-bit Windows
Windows Server 2008 Datacenter (full installation)64 GB
Windows Server 2008 Datacenter (Server Core installation)64 GB
Windows Server 2008 Enterprise64 GB

Physical Memory Limits: Windows Server 2003

The following table specifies the limits on physical memory for Windows Server 2003. Limits over 4 GB for 32-bit Windows assume that PAE is enabled.
VersionLimit in 32-bit Windows
Windows Server 2003 with Service Pack 2 (SP2), Datacenter Edition128 GB
64 GB with 4GT
Windows Server 2003 with Service Pack 2 (SP2), Enterprise Edition64 GB
Windows Storage Server 2003, Enterprise Edition8 GB
Windows Server 2003 R2 Datacenter Edition
Windows Server 2003 with Service Pack 1 (SP1), Datacenter Edition
128 GB
16 GB with 4GT
Windows Server 2003 R2 Enterprise Edition
Windows Server 2003 with Service Pack 1 (SP1), Enterprise Edition
64 GB
16 GB with 4GT
Windows Server 2003, Datacenter Edition128 GB
16 GB with 4GT
Windows Server 2003, Enterprise Edition32 GB
16 GB with 4GT

Physical Memory Limits: Windows 2000

The following table specifies the limits on physical memory for Windows 2000.
VersionLimit in 32-bit Windows
Windows 2000 Advanced Server8 GB
Windows 2000 Datacenter Server32 GB

As you can see they are all Server OS which makes me wonder, since most in fact all Drivers are certified by Microsoft, shouldn't they work with PAE? Or is it that they don't want to ?

It turns out that the reason Windows Vista/Xp 32bit "eats" up your RAM is because all hardware require memory address to map location.
Xp/Vista 32bit addresses do not exceed 4GB because Microsoft removed this functionality hence

Amount Of Space Left = Available 4GB address - Addresses Taken Up By Device Hardware

This number varies from System to System hence there is 3 ways of overcoming this issue
  1. Get a 64bit Windows OS
  2. Get a 32bit Windows Server OS listed above
  3. Hack the Windows Kernel to force enable PAE
If you are a student with Microsoft Academic Alliance in your institution you are in luck, as you can get the software free

Take a look here and here

Sorry again if my previous post caused some confusion

Power Savings With Power Plan

After using CPU-Z for a while you will notice that the CPU Core Voltage is actually not a constant value

For my AMD Turion X2 RM-72 Processor (Differs according to Processor Model)
P-State 1 is 2.100GHZ @ 1.100V
P-State 2 is 1.025GHZ @ 0.950V
P-State 3 is 0.525GHZ @ 0.800V
This is because when Clock Frequency is reduced Processor no longer requires more power to maintain stability. This is the main operating principal behind Quiet & Cool Technology

<--Credit to ComputerBase.de-->

If you check the diagram above you will notice while there are 3 P-States for RM & ZM Processors, there are only 2 available to QL & SI Processors.

Hence this indicates during idle RM & ZM Processors save more power than QL & SI Processors as they are able to go into deeper, more power saving P-States.

Hence if you are thinking about getting AMD Powered Laptop look out for ZM & RM Processors only and don't go for QL Processors since QL Processors are similarly priced for poorer Power Savings.

To take full advantage of the AMD Processor Power Saving Capability in Vista
You should create 3 Power Plans

Set Maximum Processor state to 100%, 50% and 25% for 3 different Power Plans
This will cap the Maximum CPU Voltage to 1.100V , 0.950V and 0.800V respectively
(This is for reference purposes only as different CPU has different Voltage Levels)

For example when you are surfing the internet while running on battery you might want to choose power plan that caps voltage at 0.800V to save more power.

You can argue that the processor is already doing the throttling automatically hence there is no need to interfere however, occasional CPU spikes can occur to push the frequency. Therefore by limiting max frequency you are limiting the power usage explicitly.

Another advantage you will get is that the CPU Core temperature will fall below 50 degrees if you HWMonitor it

You may think 500MHZ will lag your system, but remember this is 500MHZ Dual Core Turion Processor.
Moreover on Acer Aspire 4530, the Windows Vista Desktop rendering is offloaded to the Nvidia 9100M G GPU hence there is little or no load on Vista as compared to any Intel Graphics Solution.

However do note when running different Applications consider the Processing Power requirements. Otherwise you might encounter slow performance.
Streaming video like youtube requires higher performance or you will encounter frame skips on the videos.

The above is for Windows Vista which supports more flexible and advance Power Settings

For Windows Xp you will need a third party program Speedswitch XP as suggested by AMD Forumer Turion64Ultra

As the instructions on SpeedSwitch Xp is available on it homepage I will leave the exploration of this third party software to people who are interested

Explaining Windows Xp/Vista Startup

Note: This is applicable to BOTH Windows Xp and Vista as msconfig is present in both OS

Another reason why Windows Boot are often very slow because Programs Add themselves to the startup automatically making Windows Start the Programs on EVERY boot whether you need it or not

Start>> Run>>Type "msconfig" >> Enter

You should see this

To disable a particular startup simply uncheck the box next to the entry

If you want to remove a particular entry from msconfig scroll to the left you should see the following

The box in Red indicates the location of the registry entry which the program you installed added in order to start automatically

To remove it
Start>> Run>> Type "regedit" >> Enter

Navigate to the location in Red

You should see something like this:

To remove the entry from msconfig simply delete it from here
  • Always make sure the program you removed is non-essential otherwise certain important third party program will not run
An example from the above is "NvCplDaemon" which is actually Nvidia Graphics Control Panel
  • Unless you really don't need it, it is safer to disable startup from msconfig rather than deleting the registry entry

Upgrading your Nvidia Driver

Well, Why do you need to upgrade your Nvidia Driver?
  1. Better Performance (usually)
  2. New Features (PhyX,CUDA,Ambient Occlusion)
  3. Because you are using an Nvidia Card ! Those people using ATi Card will have to stare at your drivers which are more updated then theirs. They have to wait ... until their vendors release the drivers. Only Nvidia provide Mobile Driver support ATi passes on the responsibility to vendors
You don't have to worry about driver stability
In all my previous updates experience I didn't encounter any unstable Nvidia Drivers at all hence very unlikely

First Download GPUZ from the internet to determine your Device ID
You can also determine your Device ID by looking at the Device Manager but it is too tedious to write so I skipped it =)


Your Device ID is where I circled in RED

Next Download the New Drivers from LaptopVideo2Go here

Enter your Device ID as follows
Download any Driver they will all work but of course it is the later the better =)

Next go to Control Panel to remove the Nvidia Display Driver only

Reboot as your Computer tells you to

Then extract the New downloaded Driver
Double Click on Setup.exe
You will see some Driver Not WHQL Warning if you are installing Non WHQL Driver
Just ignore it
After installation you can delete the folder where you extracted the driver

After that check if PowerMizer is enabled here
Sometimes Beta Driver Releases leave out PowerMizer settings (Don't know why ) although all Nvidia Drivers support PowerMizer settings

Below are some new features highlights in my new 185.20 Driver




Thanks to LaptopVideo2go for providing the Drivers & GPUZ for the Wonderful Utility

Note:
Once you install certain drivers you might not be able to install driver version 185.20. This is probably due to incompatibilities in the Control Panel Version, I have yet to find a way to resolve it.

Edit:
The latest driver is no longer 185.20

Acer Aspire 4530 WEI

This is the Windows Experience Index score for my Acer Aspire 4530
Not bad for a value laptop =)
How about yours?

You should set Power Plans to High Performance to get a accurate score
You should also know the performance will vary according to RAM configurations as 9100M G is an integrated graphics which utilises System RAM

PS:To get higher WinSAT Scores Change the Windows Theme to Classic Theme and Rerun Windows System Assessment

Firefox on steroids

Have you ever wondered why Firefox is so popular?

Firefox is fast BUT that is still not the fastest it can go

To put Firefox on steroids do the following:

Type in "about:config" in the URL box (This is the secret switch which allows you to ramp up firefox performance drastically)
Of Course I am assuming you have a excellent internet connection if you are on a 56kps Dial Up no way you will notice improvements

Right Click
Create a new Integer
Enter "nglayout.initialpaint.delay"
Enter "0"

Right Click
Create a new Integer
Enter "browser.cache.memory.capacity"
Enter "-1"

Filter "network.http.max-connections"
Change the value to "64"

Filter "network.http.max-connections-per-server"
Change the value to "32"

Filter "network.http.max-persistent-connections-per-server"
Change the value to "24"

Filter "network.http.max-persistent-connections-per-proxy"
Change the value to "16"

Filter "network.http.pipelining.maxrequest"
Change the value to "8"

Filter "network.http.pipelining"
Change the value to "true"

Right Click
Create a new Boolean
Enter "network.http.pipelining.firstrequest"
Choose "true"

Filter "network.http.pipelining.ssl"
Change the value to "true"

Filter "network.http.proxy.pipelining"
Change the value to "true"

Filter "network.http.redirection-limit"
Change the value to "32"

Filter "network.http.request.max-start-delay"
Change the value to "0"


Create a new Integer "ui.submenudelay"
Set value to "0"

Then RESTART Firefox

Edit: Sorry I forgot to add how to reset the values

First you sort the value by status
Then you right click and reset them


Or alternatively

Start Firefox in safe mode, in the dialog that appears select Reset all user preferences to Firefox defaults, then click Make Changes and Restart
