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.
What does DDR2 667 mean?
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.
What is the difference between 667MHz and 800MHz RAM?
The 800MHz RAM is rated to provide data to the CPU faster than the 667MHz. However they can both operate at 667MHz or lower or even higher, though if its higher than the RAM is rated for its considered to be overclocked.
Can I use 800MHz RAM instead of 667?
Yes, in general, you can use memory of any speed as long as it fits.Can I use DDR2 667 with DDR2 800?
Normally they should work without an issue. BIOS automatically sets the speed to the slowest one. So the DDR2 800 stick should be running at DDR2 667.
Is all DDR2 memory the same?
No, you also have to take into account the voltages and frequencies your motherboard can support. Not all motherboards are equal and a dirt cheap one will not support super fast RAM.
What DDR2 800?
DDR2 PC2-6400 (commonly referred to as DDR2-800) memory is DDR2 designed for use in systems with a 400MHz front-side bus (providing an 800MT/s data transfer rate). The “6400” refers to the module’s bandwidth (the maximum amount of data it can transfer each second), which is 6400MB/s, or 6.4GB/s.
What is the highest DDR2 RAM?
The maximum capacity on commercially available DDR2 DIMMs is 8GB, but chipset support and availability for those DIMMs is sparse and more common 2GB per DIMM are used.Can I install DDR2 800 instead 667?
So long as you purchased PC2-6400 DDR2-800 DIMMs in an appropriate capacity, you can safely use them in place of the PC2-5300 DDR2-667 units specified for use with your particular machine.

Article first time published onWhat is the fastest DDR2 RAM?
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).
How do I know what RAM I need?
A simple way to know if you need more RAM is to start your workflow, then goto the Windows Task Manager (hit CTRL+ALT+DEL) and enter the Performance section. On Windows 7 or 8/8.1 you will see the RAM section at the bottom.
Is DDR2 still good?
Is DDR2 RAM good for gaming? – Quora. no it is absolutely not. if you dont want to invest a lot of money get ddr3, for GAMING (thats what you are asking for) take ddr4.
Is DDR2 still made?
No one is making DDR2 anymore, and some people are still using computers that use DDR2. So since no one is manufacturing it, as supply dwindles, the price doesn’t come down like you’d expect on older tech since it’s still in demand.
Is PC2 and DDR2 the same?
all ddr2 ram is pc2. there are two ways to classify ram, either: pc2 6400 or DDR2 800.
At what voltage does DDR3L run?
DDR3L is a dual voltage capable memory SoDIMM, which supports operation at both 1.5 V and 1.35 V.
Which is the cheapest RAM?

What is the frequency of DDR2 RAM?
DDR2 memories include 400 MHz, 533 MHz, 667 MHz and 800 MHz versions, while DDR3 memories include 800 MHz, 1066 MHz, 1333 MHz and 1600 MHz versions. Both types double the data rate for a given clock frequency.
How do I choose RAM for my laptop?
Clock speed of the RAM This must match the speed that the laptop’s motherboard supports. For example, if your laptop supports a RAM with a speed of 1600MHz, it makes no sense to insert 2100MHz RAM. Always make sure that these speeds match.
What is Sdram used for?
SDRAM (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time.
What does CAS latency mean for RAM?
The CAS latency is the delay between the time at which the column address and the column address strobe signal are presented to the memory module and the time at which the corresponding data is made available by the memory module.
What is the read and write speed of RAM?
RAM is much, much, much, much faster than even a fast SSD, as DDR3 RAM can have read and write speeds of 6GB/s and faster (17GB/s), SSD are around 200MB/s, therefore more RAM allows you to have more applications and documents open, without RAM being copied to the SSD, which is quite fast with an SSD, but RAM is still …
What information is on the RAM label?
Well many RAM sticks have a tag / sticker that lists manufacturer (HP, Micron, corsair, etc), type (DDR4, DDR3, Etc.), speed (2600 mhz, 3200 mhz) or alternate indicator (pc3–12800, etc.), CAS latency timing (cl9, cl17, etc). Barring that, there may be a model number and/or serial number, etc.
What RAM specs mean?
RAM Defined. RAM (random access memory) is memory in which all areas can be written to or read from within the same amount of time. The operating system, application programs and data in current use are kept in RAM, specifically in the chip-on-card main memory, for quick access by the computer’s processor.
What are the 3 types of RAM?
- Static RAM (SRAM)
- Dynamic RAM (DRAM)
- Synchronous Dynamic RAM (SDRAM)
- Single Data Rate Synchronous Dynamic RAM (SDR SDRAM)
- Double Data Rate Synchronous Dynamic RAM (DDR SDRAM, DDR2, DDR3, DDR4)
Is DDR2 RAM obsolete?
While you’re unlikely to find DDR2 RAM in many places today (it did become available back in 2004) it’s still useful for comparison. While original-generation DDR RAM ran two data transfers per clock cycle, DDR2 RAM can produce four transfers per cycle instead.
Will any DDR2 RAM work?
Basically any DDR2 DIMM’s will fit. However, whether these DIMM’s are electrically compatible (with the motherboard) is another matter. Check with memory manufacturers and check the motherboard memory QVL for compatible memory.
Is DDR4 better than DDR2?
DDR3 memory reduces 40% power consumption compared to current DDR2 modules, allowing for lower operating currents and voltages (1.5 V, compared to DDR2’s 1.8 V or DDR’s 2.5 V). … DDR4 SDRAM provides the lower operating voltage (1.2V) and higher transfer rate. The transfer rate of DDR4 is 2133~3200 MT/s.
