How many pins does a DDR2 SO DIMM have?
2.66" 200-pin SO-DIMM contains DDR2 SDRAM. One notch is near the side of the module.
How can differentiate the ddr1 ram and ddr 2 ram on physical look?
DDR1 RAM typically has 184 pins and a notch located closer to the center. DDR2 RAM has 240 pins and a notch positioned more towards one side. You can also look at the labeling on the RAM module itself to identify whether it is DDR1 or DDR2.
What is the difference between DDR and DDR2 RAM?
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.
Sdram has how many notches?
Sdram has one notch. Depending upon the model of Sdram the number of pins it has can vary but a standard Sdram has 184 pins.
Which type of computer memory module has 168 pins?
DDR
Which RAM technology fetches 4 bits of data per clock cycle and uses 1.8V to operate?
DDR2-SDRAM is the RAM technology that utilizes a 4-bit deep prefetch buffer and operates at 1.8V, as compared to it's predecessor DDR which has a 2-bit prefetch buffer and oprates at 2.5V. Like DDR, DDR2 transfers one bit on the rising and falling edges of the clock cycle. DDR2 takes a step further by doubling the frequency of the bus twice the rate of the memory cells. For example, a motherboard with a 133MHz FSB that uses DDR2-SDRAM for system memory, the RAM would operate at 266MHz, and then give you a 533MT data rate with a theoretical throughput of 4266MB/s.
How many pins are on a DDR DIMM?
DIMM. Two types of DIMMs: a 168-pin SDRAM module (top) and a 184-pin DDR SDRAM module (bottom). Note that the SDRAM module has two notches (rectangular cuts or incisions) on the bottom edge, while the DDR1 SDRAM module has only one.
Where can one purchase the PC2 8500 DDR2 RAM online?
Computer and electronics retailers sell DDR2 memory chips for laptops; such retailers include Office Depot and Best Buy. An owner can also contact the company that manufactures the specific laptop for computer accessories. Someone in need of this product can find these memory chips available for sale in online marketplaces as well.
What are some specifications of an Acer Aspire 5100 notebook?
The Acer Aspire 5100 notebook used the 553 MHz or 667 MHz DDR2 SDRAM technology. Its maximum memory capacity was 4GB but one was able to expand it by installing 2 SODIMM modules.
Will you have any problems if you put 667MHz ram in an iMac while leaving the other 800MHz stick in aswell?
RAM memory chips should be installed in single chips or matched pairs. You can not put in a 1GB together with a 2GB chip. You can not put in the wrong chip speed, ie a 667MHz chip. The newest iMac can support one or two 1GB or 2GB 800MHz DDR2 SDRAM SO-DIMMs. The lowest RAM is 1GB. It will also accept 2gigs via 1 2GB chip or 2 1GB chips. The max RAM is 4GB via two 2GB chips. RAM is installed in 1, 1+1, 2, or 2+2, sets.
How many cut in ddr2 ram?
ddr1 184 pins ddr2 240 pins ddr3 240 pins there are 240 pins one side 120 pins and other side 120 pins so 120+120 = 240 pins in ddr2 ram. as well as ddr3 has 240 pins and ddr1 has 184 pins only . by Prem verma from www.prem-verma.blogspot.com
Sdram or edo which would result in better performance?
If you had to choose one then you would chooes SDRAM. it is faster than EDO
