iMac - Apple Ram vs. Kensington ram

iMac is an all-in-one consumer and professional. The iMac is between the Mac mini (sold without a screen, no mouse or keyboard) and the Mac Pro (tower format sold without monitor). Everything is built around and on the back of the screen (DVD burner, motherboard, connectors, speakers, etc.).

The only external components are the keyboard, mouse and power cord. The screen is mounted on an axis that allows for rocking back and forth. No height adjustment is possible. CDs and DVDs are inserted on the right edge of the screen. Just below is the housing for the SD cameras. The various devices are taken to the back rows and the two speakers are hidden under the screen. On top of this screen, we find the integrated webcam.

The iMac is as much suited for family use (their primary audience) and professionally. And the second has yet asserted jurisdiction with the arrival in October 2009 model Intel Core i5 and i7. Quad-core processors, instead of two so far (still in use patterns of entry of a gram). The iMacs are powerful machines, comfortable with their large screens and can receive multiple devices.

Between screen 27 inch and quad-core chips with these models was a serious alternative to the Mac Pro. Who does not need to add (internal) hard drives or more cards, this high-end iMac deserves to be considered. The choice then between the Core and Core i7 i5 (€ 180) will be done of course in relation to its budget, but also in view of its use. The technology of the Core i7 as the Hyper threading is only useful on demanding applications like 3D.'s Hyper threading simulates the presence of four additional hearts . i5 Model Core is a solution fairly balanced between its price and performance.

Catering to the base 4 GB depending on model, these iMacs can go up to 8 GB of memory (21.5 ") or 16 GB (27). 4GB is an allocation consistent with all general uses: office, web, mail, iLife , but also to run Windows XP and Seven. Those who are considering professional use (designers or musicians) are likely to opt instead for the 8 GB. These iMacs are also gaming machines generally correct. Apple has a habit of using models of ATI cards and NVIDIA worthy of a midrange PC.

The units for memory strips are hidden behind a grille below the screen. The manipulation is simple, just unscrew it to access these connectors. They are four in number. To purchase new strips memories, we advise to visit the retailers Mac, PC or online sites specialize. On the Apple Store prices are usually higher than the average. The hard disk of 3.5 inches can be changed, but access is extremely delicate and reserved only for the operation and warned it is a DIY operation that voids the warranty of the machine. Better to connect one or more external USB hard drives or FireWire.

Apple Ram vs. Kensington Ram

This usually depends on your choice. I here advice to contact the Apple care directly to get a proper upgrade for your system. Expand the memory to your iMac is a very simple process. Of course, the first thing is to buy memory, but first you must know what kind of modules you need. In the case of the aluminum iMac mid-2007 SO-DIMM modules have the following
characteristics:

• PC2-5300
• Unbuffered
• No parity
• 200 pins
• 667 MHz DDR2 SDRAM

The iMac has two slots for memory and if you have not changed the factory settings, will come with a 1GB module in a slot, while the other is free. Therefore, you can buy another 1 or 2 GB with what would have 2 or 3 GB respectively, or buy two 2 GB modules for a total of 4GB. In the latter case, you replace the memory that came with your computer. As you have read, it is not necessary that the memory modules are the same, so any combination is valid considering that the maximum you can use the iMac are 4Gb.

The Apple iMac G3 500 MHz DV RAM comes from 128 MB to 1GB. The 512MB memory is of us d. Desktop Apple iMac G3 500 MHz DV certified and released. It corresponds to its quality - and system requirements. Of course, it can be used with the original modules. An upgrade of your RAM memory makes Apple iMAC G3 500 MHz d. DV again faster and more powerful.

There are other more rams provided by Kingston. Like Kingston SO-DIMM PC2-5300 Intel iMac which is a single bench with 1 GB of memory SO-DIMM 200-pin PC2-5300 DDR2 SDRAM 667MHz, memory, Apple certified and compliant with lifetime warranty. Kingston KTA memories undergo specific tests for the Apple system is dedicated to ensuring the total memory-system compatibility.

Compatible Systems:

• iMac Intel Core Duo or Core 2 Duo 1.83 GHz, 2 GHz, 2.16 GHz, 2.33 GHz and 2.4 GHz
• iMac Intel Core 2 Extreme 2.8 GHz

Who does not suffice with 4 GB of RAM that sell the iMac, just know that the maximum amount of RAM you can install on your computer is 16 GB. They say there are 4 slots to insert memory stick 2GB or 4 GB SO-DIMMs 1066MHz DDR3 SDRAM in each of these.

Type of RAM to use for Intel Mac based :

• SO DIMM DDR2 comes in 512 MB or 1 GB and works in MacBook, MacBook Pro, Mac Mini Intel, and Intel iMac.
• DDR2 DIMM comes in 1 GB, 2 GB or 4 GB and works in (ECC FB 2x512Mo or 2x1Go or 2x2GB) Mac Pro with Intel
• SO DIMM SDRAM comes in 512MB and works in iMac (700 and 800 MHz), iBook (500, 600, 700 and 800 MHz), and PowerBook G4 Titanium (400, 500, and 550 MHz)
• DDR DIMM 3200 comes in 256, 512 or 1024 MB and works in 256 and 512 MB: PowerMac G5 (1.8, 2, and 2.5 GHz), and iMac (1.6 and 1.8 GHz) 1024 MB: PowerMac G5 (1.8, 2, and 2.5 GHz)
• DIMM DDR2 5300 comes in 512MB, 1GB and 2GB and works in iMac G5 (1.9 and 2.1 GHz)

Notes :

• The more RAM your computer possesses, the more it can run programs simultaneously.
• 1 GB (Giga Bytes) = 1024 MB (Mega Bytes), the unit that quantifies the amount of memory is a byte, since a byte is 8 bits, one bit represents either a 1 or a 0 (the famous binary language).
• Usually 1 byte = 1 byte = 8 bits, careful not to confuse bit and byte then. As a result, some briefs indicate, for example a GB (which corresponds to 1 GB or 1024 MB).
• On the barrette of memory, there are two types of formats:
• DIMM 168-pin. This is a 64-bit memory. It possesses integrated circuits and other part of the PCB. Use for desktop
• SODIMM 144-pin (64 bit) or 77-pin (32 bit). This is the equivalent of a barrette DIMM, but smaller in size, for use on a laptop or a Mac Mini for example.

If you only install one memory module, install it into the slot on the right. Make sure you are in the correct position (with memory chips to you) and put it behind the plastic tab as shown in previous photo. Click to slowly and firmly until you feel that is embedded in the correct position. If the extension requires you to take the other module, just carefully pull the plastic tab until it protrudes a little memory. Remove it by hand and replaced by the other module as before, you squeeze gently but firmly. The widely used ram types on Apple iMac is PC2-6400 800MHZ.

Notes:

All iMac models have two memory slots. Except where stated otherwise, the maximum for each slot is half the total maximum. For example, a computer with a 1GB maximum can take a 512MB module in each slot. Video memory is only upgradeable in the iMac 233 MHz. Other models are not upgradeable.

The AASP Installable slot can accommodate a 1.5-inch SO-DIMM. The User Installable slot can accommodate a 2.0-inch SO-DIMM. This computer uses an AGP port. The graphics IC uses a graphics address remapping table (GART) to translate AGP logical addresses into physical addresses. The graphics driver software can allocate memory in both the dedicated SDRAM and the main memory. Purchase low-profile SO-DIMMs when purchasing larger 256 MB or 512 MB DIMMs for the User Installable slot.

The iMac G5 (iSight) has only one upgradeable memory slot, which can take up to a 2 GB module. The other slot contains a 512 MB module. Although the iMac (Late 2006) computers will accept up to a 2 GB SO-DIMM in each of the two memory slots, the iMac will only support 3 GB total memory. The iMac (Late 2009) has four SDRAM slots, each of which can accept a 2 GB or 4 GB SO-DIMM.

Conclusion:

You can add as many memory modules, how many free slots you have? But please note that the maximum capacity that can handle your device is not exceeded. Dual Channel technology increases bandwidth when using two identical arrays, i.e. it is better to use two strips of 1 GB, 2 GB only take advantage of this technology (for an update upgrade to 4 GB for example) it is necessary to buy two bars: same frequency, same capacity and same brand. Using a single strip 2GB, making the machine less efficient than with two strips of 1 GB.

Among the values of the market very safe while staying at a very reasonable price, you will find DDR3 PC3-10600 Kingston Value and DDR2 PC6400 Kingston. DDR3 PC3-8500 Kingston Value and DDR2 Kingston PC5300 can also agree, but as stated earlier, prices near you prefer the early models.

n terms of DDR, PC3200 Corsair Value is a great value. To upgrade an older machine using SDRAM, you will be attentive to any worries of compatibility. Note that you can also choose memory compatible with your motherboard LDLC with this coach and that is appropriate for your laptop with the other coach. Sites of Kingston and Corsair also offer their coach who could help you.
