How to back up d630 BIOS to CD


The BIOS is stored on a ship inside your computer and cannot be downloaded and copied over to something else. Please keep in mind that your BIOS is what boots up your computer and your OS is usually Windows. BIOS cannot be backed up but your OS can.

If you wish to backup your OS there are many ways to do that. If you have windows 7, 8, or 8.1 Windows already has a built in backup program that you can run. If you are on Windows XP or Vista then you will have to download and run your own backup software.

Casper is a good backup solution for XP http://www.fssdev.com/products/casperxp/

Hi Trifon,
you are detecting a known problem for 32 bit operating systems.
The problem for those system is that they can manage maximum 3 Gb of RAM.
If you want all of your RAM used you have to install a 64 bit operating system. Windows 7 has also a version for 64 bit as well as windows xp (but is not good supported) and windows vista.

How can i use oracle in win 7 platform of i3 processor?and which processor is best core 2 duo or core i3?


Windows 7 Release Candidate was publically released on May 5, 2009. This should be the final release before it goes live later this year. download it, install it in a VM inside of VirtualBox and try to install Oracle on it. There is no Oracle release for Windows 7, so instead grab the Windows 2008 one. The install is pretty straight forward. The only "gotcha" is that if you go to the command prompt, you need to run it as the Administrator, so that all of the Oracle commands will work (lsnrctl, dbca, netca etc...) Really there is not that much to it as it was pretty seemless. So, if you download Windows 7, then you can also download Oracle 11g and start playing with it today!


Here is the second answer


We live in the times where computing power, once available only at the level of super computers, has been made available to the common man. The forerunner in the race, who's probably miles ahead of its competitors is the computing giant Intel. According to the needs of computer users, Intel delivers chips with varying degrees of power and clocking speed. These include the entry level, mid level and high end processors. The latest entry level Intel chips to hit the market are the core i3 processors which are aimed at taking up the place previously held by the core 2 duo processors. The new hierarchy of Intel chips in ascending order of computing power are the core i3, core i5 and core i7 processors. Although core 2 duo processors are slowly being phased out of production, they are still available in the market. In this article, I present a core i3 vs core 2 duo review which may help you decide which one to go for.

Intel Core i3 Vs Core 2 Duo Comparison

A comparison between processors was simple some years ago with a single core processor. All you had to look at was the clocking frequency and the cache size. The entry of multiple core chips changed it all and life became complicated. With dual, quad and even six core processors hitting the market, there are many more factors to be considered than before. Intel's dual core and core 2 duo processors were the first ones to introduce the multicore processor computing power. The quad processors created later have given rise to the quad core vs dual core debate, as well as the core i5 vs core i7 comparison which is something that high end computing market consumers should think about. Prior to that, we only had the 32 bit vs 64 bit processors comparison.

Today, Intel has gone through a lot of designing and planning to introduce core i3 processors that are an improvement over the core 2 duo processors. The following Intel core i3 vs core 2 duo processor comparison will give you an idea about how the i3 processors are different from their dual core predecessors. The two points of comparison will be technical specifications and the only other factor which matters that is performance.

Core i3 Vs Core 2 Duo: Technical Specifications
Like the core 2 duo processors, the new core i3 line of processors, have two cores with many other technological enhancements including an integrated GPU (Graphic Processing Unit). The clocking frequency of the core i3 series of processors ranges from 2.26 GHz to 3.06 GHz. Each processor is endowed with the new line of advanced technologies including Intel developed hyperthreading, Intel virtualization and smart cache technology which makes these chips faster than core 2 duo processors. This is the most important point in the core i3 vs core 2 duo comparison.

The Intel codename for core i3 architecture is Clarkdale. They are based on the Westmere architecture with 32 nm fabrication and a direct media interface (DMI) bus. The socket type used for core i3 processors is LGA 1156 and the RAM type is DDR3. They support mother boards with the following types of chipsets- H55, P55, H57 and Q57.

Let us have a look at the latter processors in the core i3 vs core 2 duo comparison. Core 2 Duo processors come in three types of architectures, codenamed as Conroe, Wolfdale and Allendale. With 65 nm and 45 nm fabrications they are a tad slower and less power efficient than the 32 nm based core i3 processors. The socket used for core 2 duo processors is LGA 775 and they come with a FSB bus. The FSB bus is a lot slower in operation than the DMI bus in core i3 processors.

Coupled with the fact that the i3 processors have a L2 cache size of 2 x 256 kb and a L3 cache size of 4MB, with hyperthreading and smart cache enabled, core 2 duo processors are indeed slower. On top of that, DDR3 RAM compatibility in core i3 processors, compared to DDR2 compatibility of core 2 duo processors makes them even more faster. The price range of Intel core i3 is $100 to $133, which makes them top options in the entry level market.

Core i3 Vs Core 2 Duo: Performance
The technical specifications have made it clearly indicated that Intel core i3 beats its predecessor, core 2 duo in almost all departments. This is but natural as they were indeed designed to replace them. Be it processing speed, multitasking or graphic output, opting for core i3 processors is the logical choice to make!

Hope the core i3 vs core 2 duo processor comparison provided in this article has made it easier for you to choose the right processor for your personal desktop computer or laptop computer. Going for a more advanced line of processors is always beneficial in the long run. You should also check out the Intel core i5 and core i7 processors before going ahead as they offer far more computing power and speed, compared to the entry level core i3 or core 2 duo. Decide on the processor you want according to your usage requirements and of course giving due thought to your vitamin 'M' levels!

F672cr(m1610)and intel core duo?


The Acer M1610 was available with the following processors: Intel Core 2 Duo, Intel Pentium Dual-Core, Intel Pentium D/4, Intel Celeron D/4 2.0GHz.

Based on this information, It is likely that you can support a Core Duo or a Core 2 Duo, however may be limited to the 2.0GHz models due to clock and multiplier limitations on the BIOS. This may be different if there is BIOS upgrades to support faster processors.

Your best option of the above listed processors will be the Core 2 Duo, however their system specifications report that only the Core 2 with 800MHz or less Front Side Bus are supported.

Also note that the Celeron 430 is a 64bit processor, so it is not likely to work on this system either.

Difference betweeen intel celeron,core duo, mxx


Hello , Intel processors come in all shapes and sizes so I'll try to be brief by discussing only the ones that are current on the market. The market for intel processors are currently divided into 2 sides. One side if for single core processors while the other is for multi-cores. Single cores: Pentium 4, Pentium M, Celeron, Core Solo (Not very common) These cpus are single cores meaning that they only have one processor. They are relatively cheap compared to multicores. The difference between these are clock values, hyper threading, 64 bit support, and FSB. Pentium 4 and Celerons are cores found in desktops while the M is found in laptops. Single cores generally have low FSB but high clock speeds. Think of it as having a lot of water pressure but only a straw to dispense it. That's how fsb and clock values work. So single cores should provide you with a lot of raq power but they're not good at multi-tasking or jobs that requires it divide it's attention. Games like Crysis will be better with multi-cores because the pc has to generate so many different things at once while focusing on countless calculations and processes. the hyperthreading support does help the single core pentium 4s with multi-tasking but it's not as much as multicores. So if you're just looking for something with a lot of raw power. These are for you. Multi-Core Core Duo, Core 2 Duo, Core 2 Quad These are multi-core processors developed by intel. They are used in both laptops and desktops except for the quad. It's used in desktops only. The first 2 processors are dual cores while the last is quad cored. These processors have a high FSB rating and generally lower clock speed. So you have to be careful when looking at these. The high fsb means that the system does really really well with dividing and transferring it's processing power, but if you get a low clock speed then there's not enough power to begin with for the assignment. Example you may have a large hose but if you have low water pressure.. it's useless. That's why multi-cores are great for the modern pc user who multitasks way too much but if it's under 2.0ghz in clock speed. You should be worried about not having enough raw power to get you through intensive work. Multicores generally cost a lot more than single cores since they're relatively new technology. Btw the Core 2 Duo is faster than the Core Duo by about 7%. Meanwhile the quadcore is the ultimate in processor goodness but costs $400+. I hope these facts helped.

Not my friend always is going to see and have an alone CPU, this way have two cores or four cores, in addition the processors are like the memories plug and play, that is to say they do not need additional software, the firmware of the system board is the one that takes charge defining it, because of it all the system board load the BIOS to the beginning, which means Basic Input Output System.
