Are there different types of DDR2 RAM?
PC2- indicates the module uses DDR2 memory; PC- indicates the module uses DDR memory. Other common speeds for DDR2 SDRAM modules include PC2-3200 (DDR2-400; 3200Mbps throughput); PC2-5300 (DDR2-667); PC2-6400 (DDR2-800); and PC2-8500 (DDR2-1066).
Can I use DDR2-667 instead of 533?
Yes, you can use both sticks of RAM at the same time.
Can I use DDR2 800 and DDR2-667 together?
well, yes you can combine them, even though they are rated at different speeds. They will clock at 667 (being the common denominator). Or at least you should set them at that speed, otherwise you’ll be overclocking the 667 dims.
How do I identify my RAM type?
Check RAM Type Open Task Manager and go to the Performance tab. Select memory from the column on the left, and look at the very top right. It will tell you how much RAM you have and what type it is.
What is the difference between DDR2-667 and DDR2-800?
Originally Answered: What is the difference between ddr2-667 and ddr2-800? Basically different clock speeds. Clock speed is, effectively, how man ‘transitions’ something can make per second. 800 has a faster clock speed than 667, which equates to more transfers-per-second and thus more MB/s in transfer speed.
Can I use 800MHz RAM instead of 667?
The motherboard will run the RAM at 667MHz instead of 800MHz and everything will be fine. The disadvantage is that you lose a bit of performance from the lower frequency.
What is the fastest DDR2?
Corsair Dominator PC2-10000
Corsair seems determined to hold the record for the highest memory speed in production memory. We recently reviewed the highest speed memory available at the time in Corsair Dominator DDR2-1111 (PC2-8888).
Is there DDR2 4GB?
DDR2 SDRAM is a type of RAM interface first introduced around 2003. The desktop or laptop RAM is the part of the computer that temporarily stores all of the open programs and data while the system is operational. This memory module is 4GB in size.
How do I know DDR2 or DDR3?
Open Task Manager and go to the Performance tab. Select memory from the column on the left, and look at the very top right. It will tell you how much RAM you have and what type it is.
How do I know if my RAM is DDR1 DDR2 or DDR3?
Voltage of Ram, if you notice this things then its very simple to identify because each DDR Ram has unique volt. ddr1 has 2.5 voltage, ddr2 has 1.8 voltage, ddr3 has 1.5 voltage and ddr4 has 1.2 voltage.
What is DDR2 SDRAM?
Double Data Rate 2 Synchronous Dynamic Random-Access Memory ( DDR2 SDRAM) is a double data rate (DDR) synchronous dynamic random-access memory (SDRAM) interface. It superseded the original DDR SDRAM specification, and was itself superseded by DDR3 SDRAM (launched in 2007).
What is the maximum capacity of a DDR2 RAM?
The best-rated DDR2 memory modules are at least twice as fast as the best-rated DDR memory modules. The maximum capacity on commercially available DDR2 DIMMs is 4GB, but chipset support and availability for those DIMMs is sparse and more common 2GB per DIMM are used.
How many pins are in a DDR2 memory chip?
Chips and modules. For use in computers, DDR2 SDRAM is supplied in DIMMs with 240 pins and a single locating notch. Laptop DDR2 SO-DIMMs have 200 pins and often come identified by an additional S in their designation.
What is the CAS latency of a DDR2 DIMM?
At the same time, the CAS latency of 11.2 ns = 6 / (bus clock rate) for the best PC2-8500 modules is comparable to that of 10 ns = 4 / (bus clock rate) for the best PC-3200 modules. DDR2 DIMMs are not backward compatible with DDR DIMMs.
