Difference Between AM3 and AM3+ Socket

May 25th, 2011 6 comments


Question – What is the difference between the AM3 and AM3+ socket ?

Answer –

1. Socket AM3 has 941 pins while the Socket AM3+ has 942 pins ( citation and confirmation from AMD needed)

2. newer Motherboards supporting AM3+ sockets are likely to have faster memory speed support and faster HyperTransport support. So, it may be preferable to buy an AM3+ based motherboard for the bulldozer processor, rather than buying a BIOS upgraded AM3 base motherboard.

3. Mechanically the AM3+ sockets have thicker hole size ( 0.51 mm) as compared to only 0.45 mm hole size of the AM3 socket. The bigger hole increases the current carrying capacity. This improves the power delivery capability. The wider hole size in AM3+ socket will ease the insertion of the CPU in the hole. This should reduce the CPU bend problem. ( Source : ASRock)

4. The AM3+ sockets will be marked with AM3b and some socket manufacturers have used black color to differentiate it with the white color AM3 socket. The AM3 sockets are marked AM3.

5. The AM3+ socket is intended for the newer AMD Bulldozer processors, while the AM3 socket is for all the earlier Phenom ii and Athlon ii Processors.

6. The AM3+ sockets are backward compatible with the AM3 socket. All the earlier processors that worked on AM3 sockets will also work on AM3 socket.

7. The bulldozer processors can also work on some of the earlier AM3 sockets with BIOS upgrade. Some of the manufacturers have made announcements for the BIOS upgrade.

Windows 7 Experience Score 6.2 5.8

Here are some questions you may have in your mid when comparing the AMD’s Phenom ii N830 and the Intel’s Pentium P6200.

Q.  Is it true that the Pentium P6200 t has Integrated Graphics Unit ? What is its implication on comparison with Phenom ii N830 ?

A. Yes, the Intel’s Pentium P6200 has integrated Graphics Unit which helps in video encoding, video display and some entry level graphics.  A Phenom ii N830 based system will have a separate discrete graphics. The performance will depend upon the graphics component.

Q. So which one is better  ?

A. Phenom ii N830 seems to be better in overall performance and in real life computing. The Pentium P6200 does takes lead in the Super Pi calculation, but it is not reflective of the real world performance.

Some more details of Phenom ii N830

The N830 competes with the Intel’s entry level Core i3 processors ( and also with the Pentium P6100, P6200, P6300 etc) and does well in case where the number of threads are more. For low to moderate performace it is a good processor with its decent architecture. It has integrated Memory Controller and a fast HyperTransport Bus.

Some more details of Intel Pentium P6200

The Pentium P6200 belongs to the Arrandale architecture, the same architecture that powers the first generation core i3 processors. It enjoys the benefit of integrated memory controller and is suitable for low cost entry level notebooks. It has integrated gpu unit with entry level graphics performance. The lack of the Hyperthreading (One thread per core) reduces performance slightly as compared to the similarly clocked core i3 processors. Intel has attempted to gain by encashig the Pentium brand name that it created over the years

How to noindex Individual posts in WordPress

How to noindex Individual posts in WordPress

Question I have a wordpress based website and it has been it by Google Panda. It has a mix of good and bad posts. Removing the bad posts will break the links, so, alternatively, I would like to noindex the individual posts of the word press. How can I do that ? Is there a simple way to do that ?

Adam C., from Washington asked this question

Answer Hi Adam, thanks for contacting Starredreviews for your question about noindex of the individual wordpress posts. We do research a lot before providing you the accurate and to the point answers.

There are few things you can do to noindex individual posts.

1. Go to your wordpress blog admin dashboard. On the left hand side, navigate to Plugins -> Addnew. Now search for “Robots Meta Plugin” – it will take you to the screen that looks like this

2. Click on Install of the first result ( Joost et el) and install the plugin.

3. Activate the plugin in the next step.

4. No go to the individual post. On the right hand side, you should see a Table for option to select,

5. Select the noindex, follow option and update the post.

6. Do no forget to verify it by checking the source code of the individual post.

Alternatives.

If the number of the posts is very small, you can use the following method to noindex individual posts by adding the following lines in the header.php after some of the tags

ID, array(‘781’, ‘902’, ‘1123’))) {echo ”;} ; ?>

It marks the posts with ids ‘781’, ‘902’, ‘1123’ as noindex.

Noindexing bad quality pages has assumed significance after the Google Panda update where it is necessary to noindex bad quality pages.

If you have a large number of posts that you want to no index then it may be a good idea to do it directly from the mysql database ( after the installation of the Robot Noindex Meta plugin).  Make sure you save the database before trying this out.

This method is useful if you want to noindex, say, 1000 posts and want to leave only 50 pages indexed. Onnce you have no indexed all posts, you can index important pages individually. This saves time.

How to highlight Table text in html

How to highlight text of a table box in html ?

Question – I have added a table in one of the HTML pages and I would like to highlight some of the row elements in the Table. How can I do that ? How can I highlight the individual boxes of the Table ?

Mira Nair from India asked this question.

Answer – Thank you for contacting StarredReviews for your question. Highlighting the text of the background of a Table content is no different from highlighting the normal text. For example take a look at the following highlighted text.

This is a highlighted text.

The code corresponding to this text is

<span style="background-color: rgb(255, 255, 0);">This is a highlighted text.</span>

Notice that rgb(255, 255, 0) corresponds to the yellow color ( Red + Green = Yellow). You can use whatever color you want to highlight a text.

You can do the same thing for a text in the box of a Table.

As an example take a look at the following table

Table : How to Highlight Table Text

Feature Atom N550 Atom N570
Core Frequency 1.50 GHz 1.66 GHz
No. Of Cores 2 ( 4 Hyperthreads) 2 ( 4 Hyperthreads)

The corresponding code is as follows

<strong>Table :  How to Highlight Table Text</strong>
<table border="1">
<tbody>
<tr bgcolor="000099">
<td><strong> <span style="color: white;">Feature </span></strong></td>
<td><strong> <span style="color: white;">Atom N550</span></strong></td>
<td><strong> <span style="color: white;">Atom N570</span></strong></td>
</tr>
<tr bgcolor="ghostwhite">
<td><strong> Core Frequency</strong></td>
<td><span style="background-color: #ffff00;">1.50 GHz</span></td>
<td><span style="background-color: #ffff00;">1.66 GHz </span></td>
</tr>
<tr bgcolor="gainsboro">
<td><strong> No. Of Cores</strong></td>
<td>2 ( 4 Hyperthreads)</td>
<td>2 ( 4 Hyperthreads)</td>
</tr>
</tbody>
</table>

Alternatively you may also set the background of a box of Table as follows.

Table : How to highlight Table Text

Feature Atom N550 Atom N570
Core Frequency 1.50 GHz 1.66 GHz
No. Of Cores 2 ( 4 Hyperthreads) 2 ( 4 Hyperthreads)

The corresponding code is as follows. We make use of the code like <td bgcolor=”ffff0000″>  to do the same.

 

<strong>Table :  How to highlight Table Text </strong>
<table border=”1″>
<tbody>
<tr bgcolor=”000099″>
<td><strong> <span style=”color: white;”>Feature </span></strong></td>
<td><strong> <span style=”color: white;”>Atom N550</span></strong></td>
<td><strong> <span style=”color: white;”>Atom N570</span></strong></td>
</tr>
<tr bgcolor=”ghostwhite”>
<td><strong> Core Frequency</strong></td>
<td bgcolor=”ffff0000″>1.50 GHz</td>
<td bgcolor=”ffff0000″>1.66 GHz</td>
</tr>
<tr bgcolor=”gainsboro”>
<td><strong> No. Of Cores</strong></td>
<td>2 ( 4 Hyperthreads)</td>
<td>2 ( 4 Hyperthreads)</td>
</tr>
</tbody>
</table>

Binary to Decimal Conversion

May 21st, 2011 No comments


Binary to Decimal Conversion

The decimal equivalent of a binary number is obtained by multiplying each binary digit with its positional value.

The Definition of the Positional Value

The right most bit has positional value 20 or 1 the second right most bit has value 21 or 2 and so one.

Comparison with the Decimal System.

To better undestand the analogy with the decimal system. Consider this – the right most bit has positional value 100 or 1 the second right most bit has value 101 or 10,  the  third right most bit has value 102 or 100 and so one.

Example 1

Convert the binary number 11001 into its decimal equivalent.

Answer

11010 (Binary number) =1×24 +1×23 +0x22 +1×21+0x20=16+8+0+2+0=26(Decimal Number)

(11001)2 =(26)10

Example 2
Convert 111101101112 to decimal equivalent number,

Answer

111101101112 =1×210 +1×29+1×28 +1×27+0x26+1×25+1×24+0x23+1×22+1×21+1×20=197510

To under stand it with existing Decimal system consider expression of th value of the 345 in decimal system with base 10. It can be expressed as

345 = 3×102 +4×101+5×100
