Upgrading the processor

Hello,

I have Samsung R510 laptop. It has Intel core duo processor. I would like to upgrade it with core 2 duo processor. I have some question about it;

1- Is it possible to use core 2 duo processor in my pc? in other words, core duo socket is same and compatible with core 2 duo?

2- If core 2 duo processor worked in my pc, can I install 64 bit Operating system?

3- 32bit Ubuntu is installed in my pc. Although I have 4 gb ram installed in the laptop, Ubuntu recognize only 3 gb. If core 2 duo processor worked in the laptop, can it recognize 4 GB ram ?

Cheers,

Unfortunately the answer to all your questions above is NO! :)

To upgrade from Core Duo to Core 2 Duo you will need to replace the motherboard as well.

Core 2 Duo is not a 64bit processor by default! 64bit Processors are clearly marked with the 64bit logo.

The processor has nothing to do with the OS recognizing more RAM. It's an Ubuntu issue.. Try a newer release..

Hey,

Here is the answer for you:

1. Bot of them has the Socket-M (PGA/BGA) support, which means you can upgrade your laptop processor.
2. Yep, you can install a 64 bit OS.
3. If you install any of 32bit operating systems on your PC, they will never recognize more than 3 GB of ram, thats because the addresses limits 2 exponent 32 = 1~4GB but there is limit on the 32 OS to show only 3. To see all the amount of memory try to install a 64bit OS.

If you have any questions, keep asking !

Happy update !

According to your manufacturer you can use the following processors for your model:
Intel® Centrino® 2 Processor Technology
Intel® Core"2 Duo Processor
Intel® Pentium Dual Core"
Intel® Celeron® Processor

If I were you and I was about to spend the money to buy a new processor I would buy the Intel® Centrino® 2 Processor Technology instead of the Intel® Core"2 Duo Processor.... It is so much better....

Is Intel Centrino 2 processor newer and faster than Core 2 duo?

Yes and it saves your battery life as well.

I sent you all the links so you can verify what I am saying....otherwise, you can fall into the confusion stage you were at above.... Nothing like a good link from the manufacturer to clarify things and avoid making expensive mistakes. On the Samsung site, the processors are placed in order of newest/better, so this is the order:
Intel® Centrino® 2 Processor Technology
Intel® Core"2 Duo Processor
Intel® Pentium Dual Core"
Intel® Celeron® Processor
As you can see from the above.... the Celeron is the worst.

This is nothing personal, I understand that you are very worried about the points. Unfortunately your answer was not as complete as it should have been. You were aware that your answer would conflict with the previous answer and that it would create conflict and confusion to Delidumrul.
You should have supported your answer with links and a more thorough explanation to avoid this.

BitsBytesandMoreCommented:
In any case .... I assisted you and Delidumrul in providing a solution to the question.

I don't care about the points, all i care is about justice. I made a research and spent a hour while i am at work to provide this great answer. To add links its very cheap and easy, but to support a literal answer much harder, so please appreciate this and give me all the points.

Thank you all.

"...all i care is about justice. I made a research and spent a hour while i am at work...." If it is about "justice" you should tell your employer to discount this hour from your pay..... it's called "stealing".
".....provide this great answer..... " It was not a GREAT ANSWER. It lacked supporting evidence and created confusion.
You are new to the EE forums. You should hang around a while to see how things are done here. The way you answer and behave establishes your reputation among other experts. Keep this in mind for the future.
Whenever you answer a question, if possible, you should support your answer. Many times you see someone say "Yeah... go ahead" and it has proven to have devastating consequences.

You are right man, i should follow the rules of the experts.

So considering the fact i am new here i'd suggest to give me half of the point to make me feel i didn't work for nothing, it will motivate me to answer a better future answers.

B grade will be enough, thanks again :)
