What is the difference between PC1600 and PC2100? Are they both DDR?

SpecTek Select - Welcome
PC1600 is designed for use in systems with a 100MHz front-side bus (effectively 200MHz in DDR mode). PC2100 is designed for use in systems with a 133MHz front-side bus (effectively 266MHz). However, since PC2100 was designed to be backward compatible, it has essentially replaced PC1600 in systems with a 100MHz front-side bus.

Will PC2100 work with PC1600?

SpecTek Select - Welcome
Yes. However, if you have a system with both PC1600 and PC2100 modules, the system will only run at a speed of PC1600. A system will only run at PC2100 if all the modules in it are PC2100 and the system supports PC2100.

What do the numbers in PC100 PC133 PC1600 PC2100 and PC2700 stand for?

SpecTek Select - Welcome
In order to qualify as PC100, PC133, etc., a memory module must meet industry standards for use in a particular type of system. In SDRAM modules, the numbers that come after the "PC" refer to the speed of the system's front side bus. In DDR modules, the numbers that come after the "PC" refer to the total bandwidth of the module. Here's a short summary of each type. PC100 memory is SDRAM designed for use in systems with a 100MHz front side bus.

What is the difference between PC2100, PC2700, and PC3200?

SpecTek Select - Welcome
PC2100 DDR is designed for use in systems and motherboards which require a 133MHz front-side bus. While the system or motherboard may operate a 133MHz front-side bus, its effective front-side bus speed is 266MHz in DDR operation. To get the effective front-side bus speed of a DDR system, double the operating frequency. PC2700 DDR is designed for use in systems and motherboards which require a 166MHz front-side bus, with an effective front-side bus speed of 333MHz.

What is the difference between SDRAM and DDR memory?

PCEX - FAQs
SDRAM (single dynamic randomn access memory) is the older style of memory with 2 notches on the stick. The speed of SDRAM is either 100 or 133 MHz (older SDRAM was 66 MHZ - do not mix with pc133 memory !) DDR (double dynamic rate) memory has only 1 notch. The DDR memory will read twice (double) as much information as the SDRAM - the speed of DDR is from 266 to 400 MHz

What is the difference between DDR and SDRAM?

Welcome to Neighbours Computers!
DDR RAM is designed to run at Double Data Rate unlike older memory like SDRAM (Synchronous Dynamic RAM) this DDR capability is further enhanced by the actual speed of the RAM ie; PC66, PC100, PC133, PC2100 and now even upwards of PC3200.

What is DDR?

Easy Conference Rooms Frequently Asked Questions
Day Delegate Rate. This is the cost per person in hiring the conference room. Day Delegate Rates normally come as a package typically including room hire, teas/coffees and lunch. DDR packages will vary from operator to operator and package to package.

What is the difference between PC2100(DDR266), PC2700(DDR333), and PC3200(DDR400)?

Frequently Asked Questions - MemoryOnlineShop
Although these are all types of double data rate (DDR) memory, the varying numbers refer to the different speeds of memory your computer was designed for. Crucial no longer carries PC2100 (DDR266) memory, but PC2700 (DDR333) memory and PC3200 (DDR400) are backward-compatible with PC2100. Memory is designed to be backward-compatible, so generally speaking, you can safely add faster memory to a computer that was designed to run slower memory.

Can I play DDR for anything other than computer?

DDR East Invasion
Playstation (1) is the best system for playing DDR aside from computer. Check out the store section for a few places to buy the games for playstation.

What is DDR Technology?

FAQ: DDR SUPPORT & TEST RESULTS
Double Data Rate (DDR) technology is the modern variant of Synchronous DRAM technology, providing the fast bandwidth needed by today's high speed computers. DDR is similar to SDRAM in the sense that the commands and data accesses are synchronized to the system clock. DDR technology further increases the data throughput by transferring two data for each clock cycle - one data is transferred when the clock goes high, another when the clock goes low.

Will DDR work in my system?

SpecTek Select - Welcome
DDR DIMMs only work in DDR systems. Your system's motherboard must have 184-pin DIMM slots and a DDR-enabled chipset.

How do I play DDR, or another music game, on my computer?

DDR East Invasion
There are a number of different simulators that let you play ddr on your computer. You can buy pads (usually serial port pads) and use those, or just use a keyboard/controller. The simulators section of 'links' has a few places to download the programs themselves.

Where can I buy pads to play DDR?

DDR East Invasion
RedOctane is the number one source for DDR in the US. For a list of pads for sale there, check out the DDR Pads section.

Is a there a typical DDR package?

Easy Conference Rooms Frequently Asked Questions
There are a number of packages depending on your requirements and budget. A typical package will include the hire of the conference room, servings of teas/coffees throughout the day including biscuits and a lunch (sandwiches, fruit and pastries). Bottled water will normally be included as well. Please discuss your requirements with one of our advisers. Call our reservation team on 0800 082 9810 or email the team at reserve@easyconferencing.co.uk.

What are 240pin DDR Dimms?

Offtek.co.uk |
pin DIMMs are used to provide DDR2 SDRAM memory for desktop computers. Each 240-pin DIMM provides a 64-bit data path (72-bit for ECC or registered modules), so they are installed singly in 64-bit systems. pin DIMMs are available in DDR2 PC2-4200 (DDR2-533) SDRAM or DDR2 PC2-3200 (DDR2-400) SDRAM. To use DDR2 memory, your system motherboard must have 240-pin DIMM slots and a DDR2-enabled chipset.

What are 172pin DDR MicroDimms?

Offtek.co.uk |
A 172 Pin DDR MicroDimm is 1.75" in length x 1.25" high and is designed for laptops. Each 172-pin MicroDimm provides a 64-bit data path, so they are installed singly in 64-bit systems. Computer Memory | Laptop Memory | Desktop Memory | Digital Camera Memory | Server Memory | Workstation Memory

Can RAMCHECK support DDR modules?

FAQ: DDR SUPPORT & TEST RESULTS
Yes. RAMCHECK's optional DDR 184-pin Adapter (p/n INN-8668-6) supports modern 184-pin DIMM DDR modules and is at the heart of our new DDR Series. A low-cost converter (p/n INN-8668-6-1) supports 200-pin S.O. DIMM DDR modules. Due to the importance of DDR technology, we have introduced the RAMCHECK PLUS bundle, a combination package of RAMCHECK and the DDR adapter.
