12 core processor from AMD - AMD Opteron 6100 series

I think the old furious processor war between Intel and AMD resume soon. In AMD official blog they claim ,they on the way to deliver new 8- and 12-core processors with high performance. If it is right let us wait and see another episode of processor war which held few years back. They says AMD 6100 series (12 core processor) processor for cloud environments and a little expensive as more than $1000.

It is announced that Acer will be the pioneer using AMD's Opteron 6100 serious in their systems. Technically speaking Opteron 6100 series consist of 10 chips with either eight or 12 cores. Each core offering clock speeds ranging from 1.7GHz to 2.4GHz. John Fruehe, AMD's Director of Product Marketing is very optimistic about the new product.He is saying "The big thing we will be doing is delivering more cores and more memory for less money". AMD claims their Direct Connect Architecture 2.0 can support up to 16 cores per CPU. Any way let us wait for the release of new 12 core processor from AMD and its equivalent competitor from Intel family.

Use Flash Memory (USB) as Virtual RAM in Windows 7 and Vista

If you feel your computer is lacking enough RAM, you can increase it by using USB memory as virtual Random Access Memory. This technology is called ReadyBoost and  Microsoft enabled it on Windows 8, 7 and Vista. When you connect a flash memory card, Windows will ask you if you want to use the unused portion to speed up your PC. If you click OK, Windows converts the unused portion to virtual RAM. We cannot use all kinds of USB memories to speed up our computers. It should meet some minimum requirements to enable ReadyBoost technology.


System Requirements to Use USB Memory as Virtual Primary Memory
  • It should be at least 256 MB

  • It should have access time of 1 ms or less.

  • It should have at least 2.5 MB/s read speeds and 1.75 MB/s write speeds

Convert USB Flash Drive to Virtual RAM

It is not very hard to convert USB flash drive to virtual RAM using ReadyBoost technology. If you have Vita or higher version on your PC, it is very simple. You cannot use this technology on Windows XP computers.
  1. Connect USB Drive to Universal Serial Bus port

  2. Right click on USB drive and click properties
    ReadyBoost - Speed up your computer using USB stick

  3. Click on tab ReadyBoost and apply
Now, if your Flash memory meets all the requirements mentioned at the beginning of this guide, it will be converted to virtual RAM and you can see a considerable improvement in system performance.


Points to Remember while using ReadyBoost

In Windows Vista, it is limited to 4 GB while Windows 7 can support up to 256 GB of additional memory by connecting maximum 8 different flash drives. Windows OS older than Vista don't support ReadyBoost technology. Currently Windows Server 2008 is also not supporting it.

How to Fix MBR ( Master Boot Record ) Damages Using Fdisk Commands

MBR (Master Boot Record ) is stored in the first sector (512-byte) of hard disk and contains primary partition table, disk signature and instructions for BIOS to boot the computer are stored. It is stored outside the partition. It is created while hard disk partition. Any damage to this area is fatal because it can even stop your PC from booting. Damages to Master Boot Record can happen due to improper installation of multiple Operating Systems, certain virus attack and hard disk error. This tutorial explains the reasons for MBR damages and quick fix to it.

Possible Reasons of MBR Damage

  1. Possible Virus attack

    There is a special type of malware called MBR virus, with capability to damage the Master Boot Record by replacing the original MBR with another one created by it. Original Master Boot Record sector will be moved to some other locations in the hard disk. These viruses can start with system boot-ups even before loading OS and escape from normal Anti Virus scanning.

  2. Hard Disk Drive error

  3. Improper installation of multiple OS

Ill Effects Of a Damaged MBR

In most cases, users will find difficulties with starting their computers in safe mode. They will either don't see safe mode option in boot menu or safe booting fails. If the damage is big, your PC may not start at all. So it is very important to fix any corruption as soon as possible.

How to Recover Corrupted Master Boot Record

To recover this sector, we have some tools which operate in recovery mode. We cannot actually change the MBR while Windows is running. Those recovery commands are provided below.

  1. Fdisk /mbr

    The MS-DOS command Fdisk /mbr rewrites the MBR on the disk and it will resolve all corruptions. This command is useless if your computer is infected with MBR viruses because they will again reinfect the new Master Boot Record sector. Hardware specialists do not recommend this command to fix issues and they recommend another command. That is the next one.

  2. Fixmbr

    This command works in Recovery Console only. The command, fixmrb, provides us a option to specify the location of master boot record. It helps to fix the mbr of devices other than the master boot device. Only downside I see is the requirement of Windows Disc while running this tool. If you use this tool to recover MBR of another device (not the master boot device), you must use the following format.

    fixmbr (device_name)

Steps to run Fixmbr on your computer

  • Restart PC

    Restart your computer with Windows CD, where DVD/CD drive is the primary boot device.

  • Recovery Console

    Press the R key to start the Recovery Console when it prompts.

  • In Recovery Console command prompt, type fixmbr and follow the instructions

Delete Saved Preferred Wireless Network Profiles On Windows 8, 7 & XP

Windows OS has the ability to remember WiFi profiles on your computer once you join the network. We call preferred networks to denote these saved WiFi profiles which consist of details like SSID, wireless key, encryption etc. When you are back in range of a saved profile, your PC will automatically connect to it. Though this feature is helpful, rarely it makes some issues too. In case if admin changed the wireless key, your PC will try to use the old information to join it and cause connectivity issues. In that case we need to delete the old saved profile. On Windows 7 and XP we can do it from Graphical User Interface but there is no such option available on Windows 8. If your PC runs on Windows 8, you must use Command Prompt to see the preferred network and you must delete any of them from there only. This tutorial explain how to view and remove any preferred networks on your system.

Delete Saved Wireless Networks On Windows 8

This Operating System does not offer any straight ways to remove preferred WiFi details from GUI and we should go to Command Prompt to perform it.

  1. Type cmd on Search and Open Command Prompt

  2. Type netsh wlan show profile and press enter to view all saved preferred profiles

  3. Type netsh wlan delete profile name=name of the one you want to delete and press enter

This procedure will delete all information stored on your PC related to that profile.


View or Edit Saved wireless networks On Windows 7

Here we can use GUI to find list of preferred networks stored on a laptop.

  1. Click on Start

  2. Click on Control Panel

  3. Click on Network and Internet
    How to edit preferred wireless networks on Windows 7

  4. Click on Network Status and Tasks
    See saved wireless networks profile

  5. Click on Manage Wireless Networks panel
    Manage Wireless Panel on Windows 8

    Now the all stored WiFi details will be shown. You can select the anyone from the list (preferred profiles ) and click on remove.  After this, your computer no longer remember that network.

You can use the same command prompt procedure to perform this task on Windows 7 too. Since it is already explained, I am not repeating the same steps. You can use same steps to view and remove any expired wireless profile from your computer from Command Prompt using the command netsh wlan delete profile name=name of the profile.

Manage Preferred Networks On XP

If your computer runs on XP Operating System, you can manage all WiFi profiles stored on your PC by following the instructions provided in the link below.

Firefox Right Click Menu Doesn't Have Properties Option

After upgrading  from Firefox 3.5.5 to Firefox 3.6, I couldn't see properties option in right click menu. When I right click on a link to find the link properties, I failed to find properties option in the right click menu. At first I thought my computer may have infected or some add-on conflicts causing this issue. I checked Mozilla support for the issue (missing element properties in Firefox 3.6 menu) and found that Mozilla team has removed this feature from their latest update. I cannot understand why they have removed this option and I couldn't find any equivalent feature. I am not alone, many users are not happy with this unexpected move of Mozilla team and we really want this element back as soon as possible.


Update: Mozilla team introduced a new plugin to bring back missing properties option in Firefox 3.6 at last.


Mozilla team introduces a new add-on to bring back the missing option in Firefox 3.6 . To install this add-on to bring the missing option back to  latest versions, visit the link below. Instructions to install this pluggin is explained below.

Reports of Possible Bug

There is a report saying that the missing of properties option was due to a bug(#513147) and was not an intentionally made change. Since there is no official declaration about it yet, I won't be able to conclude whether it is a bug issue. I am still waiting for an official announcement to clarify this issue.
