I just put a PC2 6400 in the slot that had DDR2 533. The motherboard beeped when I turned the computer on. This beeping is an indication that the memory is not installed. Therefore in my case the answer is no.
The DDR2 533 RAM is in fact compatible with an iMac. It is very advisable to upgrade an iMac with a DDR2 533 RAM as iMacs are really not known for their RAM.
Goto http://en.wikipedia.org/wiki/DDR2_SDRAM. Scroll down a bit til you see chips and modules. But for those that are less computer literate: DDR2: the type of memory. -400 -533, etc.: the speed of that memory. The numbers represent a certain specification within that type of memory. Higher number=faster. So if your Motherboard supports both and youre trying to decide which to buy, get the 533. It's a bit more expensive, but you'll get much better performance.
Is a memory of 256 Mb
The Acer Aspire 3620 Notebook computer can use DDR2 PC2-4200 (DDR2-533) or DDR2 PC2-5300 (DDR2-667) which are 200-pin SODIMM modules. The Acer Aspire 3620 has two memory slots and each slot supports up to 1 Gigabyte of RAM for a total of 2 Gigabytes. This system uses unbuffered, Non-ECC, 1.8 Volt RAM.
Ya sure you shall go for it It will run at the slower clockspeed though, but not a big issue.
Remove the back of the Vodaphone 533 and right next to the sim card is the slot for the micro memory card.
DDR2. Theres several diffent speed DDR modules, exactly what you will need depends on what CPU you are using, but the slowest DDR2 you can use in this motherbaord is 533, and the fastest DDR2 800. 800 is probably the best to use.
As long as it is made for a laptop i dont see why i couldn't work. make sure you have a free ram slot or remove one so you can put it in though.
Most desktops and notebooks use one of the three most popular types of synchronous dynamic random access memory (SDRAM) for the main system memory. Single data rate (SDR) SDRAM is the older type of memory, commonly used in computers prior to 2002. Double data rate (DDR) SDRAM hit the mainstream computer market around 2002, and DDR2-based systems hit the market in mid-2004. DDR SDRAM is a straightforward evolution from SDR SDRAM. The big difference between DDR SDRAM and SDR SDRAM is that DDR reads data on both the rising and falling edges of the clock signal, so the DDR module can transfer data twice as fast as SDR SDRAM. While DDR has a limited clock rate, the evolutionary changes to DDR architecture enable DDR2 to achieve speeds beyond of DDR, delivering bandwidth of 5.3 GB per second and beyond! Because DDR2 is able to operate with faster bus speeds, your memory doesn't hold back the performance of your processor. Generally speaking, motherboards are built to support only one type of memory. You cannot mix and match SDRAM, DDR, or DDR2 memory on the same motherboard in any system. They will not function and will not even fit in the same.
Yes you can. You can use any combination of DDR2 memory (533, 667, 800 MHz) mixed, BUT total memory will run on the frequency of the slowest of the bunch. So, if you have 512MB@533MHz and you want to add 2GB@800MHz, you'll end up with 2,5GB@533MHz.
No. They are different generations of DDR.
You can get memory with more capacity, but your motherboard probably doesn't accept faster memory (533 or 667 memory).
