What is the Meanimg of ddr ram?

DDR-RAM is an eponym for: double data rate synchronous dynamic random access memory - this is a type of a very fast computer memory. DDR-2 is even faster and now a bit of the most common and price effective memory available but uses a different memory slot ddr-3 is the new kid on the block, is fast, and pricey


What does 4gb ddr2-800mhz sdram mean?

It is a type of RAM (Random Access Memory) Broken down, it is 4 gigabytes (the amount) double data rate 2 (the improved version if DDR) 800 megahertz (the speed) synchronous dynamic random access memory(the type)


Can you play games that run on 2 GB ddr2 ram on 2.25gb DDR ram?

The type of RAM your motherboard supports can only use that type and no other. If you have DDR2, you can not place a DDR or DDR3 module. If you mean can the game run the same on another system with different RAM, then quite possibly, but the speed of that memory may not be suitable for it.


What does prefetch 2n mean in regards to a ddr memory module?

DDR1 has a prefetch of 2n, which means it can store 2 bits of data in each prefetch buffer.


What is the differenc with memory PC 2 5300 pc5400 pc5000?

PC2 refers to DDR2 SDRAM, which is a second generation of DDR SDRAM (Double Data Rate, Synchronous Dynamic Random Access Memory). It features many technical improvements over the older DDR memory. Most notably is the doubled clock speed over DDR at the disadvantage of increased latencies. The number after PC2 refers to the maximum theoretical speed (in megabytes per second) that the memory can transfer. For example, PC2-5300 memory can theoretically transfer data at 5,300 MB/s, or 5.3 GB/s. DDR2 is not compatible with motherboards that use DDR or DDR3. When purchasing memory for a computer, check your computer manual for the correct type of memory for your computer. If you are not confident that you can choose the correct type of memory for your computer, have a professional service it.


What is the approximate operating frequency of DDR-2 memory rated at PC2-5300?

667 MHz


Are all DDR SDRAMs interchangeable?

Yes, but only with other DDR, not SDR. DDR is 184 pins where SDRAM is 164 pins. There are a few factors that will affect the speed of you memory: 1) The memory itself If you buy cheap memory then you might have slow memory. the chip can only move as fast as its slowest memory section 2) Maximum clock speed on the motherboard Your memory will only run as fast as your mobo can run it. If your mobo supports up to PC2700, buying PC3200 will only run at PC2700 speeds


Were can you buy 2GB DDR PC3200 memory?

Someone that is looking to purchase a 2 GB DDR PC3200 memory card can do son at Best Buys or even Future Shop. If someone prefers to shop online then one can use the websites eBay and Amazon.


Is a DRAM variation that is designed for computers with multi-core processors?

That would be DDR-3 memory. Some multi-core systems use DDR-2 memory. Then of course there is cache memory, but that is a variation of SRAM, and it has been used ever since the 386 or 486 machines. Nowadays, cache memory is not in discrete chips, but a part of the processor. Placing the cache memory and memory controller on the CPU die greatly improves the throughput.


How would you determine what type of RAM is needed for the computer?

you would need to do research or call the company and ask just search it up and it should tell you that you need either DDR 1 DDR 2 or DDR 3


What memory ram for GigaByte GA-945GM-S2 Motherboard?

# 4 DDR II DIMM memory slots (supports up to 4GB memory) # Supports 1.8V DDR II DIMM # Supports dual channel DDR II 667/533 DIMM # DDR2 PC5300/PC4200 # 512MB or 1GB Modules # Install like memory in each channel for Dual Channel operation # If only 2 DIMMS installed, place in same channel (slot color) for Dual Channel, if installed in adjacent slots, memory will run in single mode.


What prevents a ddr dimm from bein installed in a ddr 2?

ddr dimm is not compatible with the ddr 2 because of the notches. the different notch positions will keep you form installing it.
