What does the documentation mean when referencing DDR2 533/667/800MHz RAM? The module is double data rate 2 nd generation, and the sequence of numbers refer to the rate of the data being transferred.
Likewise, can I use 800MHz RAM instead of 667?
2 Answers. The DDR2 RAM can be run at lower frequency without any issue. 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.
Secondly, what does pc2 mean on RAM? DDR2 Specs
| Friendly name | Industry name | Peak Transfer Rate |
|---|---|---|
| DDR2-533 | PC2-4200 | 4266 MB/s |
| DDR2-667 | PC2-5300 | 5333 MB/s |
| DDR2-800 | PC2-6400 | 6400 MB/s |
| DDR2-1000 | PC2-8000 | 8000 MB/s |
Beside above, what is the highest ddr2 RAM?
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.
Are all ddr2 RAM the same?
No, there are different types of DDR2 modules. DDR2 is more thought of as a specification. There are desktop and laptop modules as well as different speeds such as PC2-3200, 4200, 5300, 6400 and 8500.

What is the difference between ddr2 667 and 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.
What is the difference between 667MHz and 800MHz RAM?
Distinguished. It’s more or less a capability rating. 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.
Is there ddr5 RAM?
DDR5 Release Date Back in March of 2017 JEDEC announced that DDR5 was being worked on and should be released in 2018. Jumping forward to November 2018, SK Hynix finally announced the first ever DDR5 compliant RAM module, which they in turn said would be available to consumers come 2020.
Is ddr2 RAM good for gaming?
yes, but any platform that has ddr2 ram likely has a cpu that’s too old. You can’t just snap a 4790k on a motherboard with ddr2 slots.
How do I know if my RAM is ddr2?
Distance of Notch Notch Means above cuts Marks on RAM. DDR1, DDR2, DDR3 having Single Cut mark on the base of the RAM. But you can see the Cut mark (Notch) distance (see below photo) Notch of DDR1 and DDR2 are similar but if you see closely, You can find DDR1 Notch is just above the IC and DDR.
Can I mix ddr2 667 and 800?
If you do mix speeds, the modules will all run at the speed of your slowest modules. For example, for a DDR2 667MHz system you could add 800MHz modules, they will run at the 667 speed. You cannot mix DDR, DDR2, DDR3 in a system as each technology requires a different type of socket.
What is the fastest ddr3 RAM?
Fastest DDR3 RAM is 3.2Ghz G. skill Trident X , the fastest DDR4 right now is only 100Mhz above that.
How fast can ddr3 go?
Thus with a memory clock frequency of 100 MHz, DDR3 SDRAM gives a maximum transfer rate of 6400 MB/s. The DDR3 standard permits DRAM chip capacities of up to 8 gibibits, and up to four ranks of 64 bits each for a total maximum of 16 GiB per DDR3 DIMM.
What is the speed of RAM?
RAM speed is measured in Megahertz (MHz), millions of cycles per second, so that it can be compared to your processor’s clock speed. For Dell desktops and laptops, memory speed can range from the standard 1333MHz all the way up to speeds of 2133MHz.
How do I know my DDR speed?
How to Calculate Memory Transfer Rate Determine the bus clock rate. This information should be labeled on the memory’s packaging. Multiply the bus clock rate by 1, 2 or 3 depending on how many streams of information are flowing at once. Multiply the result from the previous step by 64, which is the number of bits transferred.
Can ddr2 fit in ddr4?
No. DDR2 uses 240 pins while DDR4 uses 288 pins. There is also a notch placed differently that won’t allow it to fit.
How do I know if my RAM is ddr3?
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. In the screenshot below, you can see that the system is running DDR3.
What is pc2?
PC1 is also known as Gross Profit. It can even show the profit contribution of the unit economics of fulfilment and delivery services. PC2 is calculated from PC1 minus indirect costs (e.g. technology, auxiliary staff, outsourcing costs, etc).
Does RAM speed matter?
Your RAM’s speed does not alter how fast your CPU goes, even when overclocked or hyper-threaded, but it can slow the CPU down depending on if your RAM is full or not. RAM speed comes down to how much data is transferred at a given time, and much of that can be determined by the number of your RAM module.
