Can I mix DDR2 667 and 800?
If having a 2GB DDR2 800MHz and a 1GB DDR2 667MHz is not compatible.
What is the max MHz for DDR2?
DDR2 ranges from 400MHz – 800 MHz. Using overclocking it can go upto 1250MHz.
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.
Is 800 MHz RAM better than 667 MHz?
If you buy fast RAM you’re basically paying for overclocking headroom. The difference between 667MHz and 800MHz is quite marginal and basically for 800MHz you get to up the FSB a bit more than you otherwise would with a 667MHz chip.
Are all DDR2 RAM compatible?
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 DDR2 RAM good for gaming?
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. i got ddr4 in my gaming pc 16gb everything is smooth. you could experience lags with just 8gb of ddr3, some say its enough.
What is the clock speed for a DDR rating of DDR2 800?
Both DDR2 and DDR3 have a single clock that runs at the same speed at the I/O bus – for example, a DDR2-800 module has a 400MHz clock.
Is PC2 and DDR2 the same?
Any memory that says either DDR2 or PC2 means the same thing. Likewise DDR3 is the same as PC3. The other numbers indicate the speed of the memory. You should always try to match the speed (i.e. 6400, 10666, 12800, etc) on all sticks you put in the same machine.
What is PC2 memory?
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).
What is 667mhz RAM?
667mhz is half of 1333mhz, which means that your ram is running at 1333mhz, which is standard.
What is the fastest DDR2 RAM?
Corsair Dominator PC2-10000: Fastest DDR2
| Cosair XMS2 Dominator Modules | ||
|---|---|---|
| PART NUMBER | SPEED | SIZE |
| TWIN2X2048-10000C5DF | XMS2-10000 | 2048MB |

| TWIN2X2048-8888C4DF | XMS2-8888 | 2048MB |
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. Therefore, the listed clocks are nominal clocks, not real ones.
Does DDR2 support 4GB RAM?
This DDR2 memory module meets the needs of high data transmission performance for game players. High memory frequency up to 667MHz creates a super high speed data transmission. Furthermore, 4GB RAM makes sure a stable and smooth game playing experience.
What’s the fastest DDR2 RAM?
Corsair seems determined to hold the record for the highest memory speed in production memory.
Are there different types of DDR2 RAM?
Is all DDR2 RAM the same?
Why is my ram speed at 667?
The memory is running at 667 MHz, which equals 1333 MT/s because of the Double Data Rate that gives DDR3 its name. Your kit is rated to run at up to 1866 MT/s, which is actually only 933 MHz. Most kits default to 1333 MT/s = 667 MHz, so you need to go into BIOS/UEFI and set it to the faster speed.
Does MHz matter in RAM compatibility?
If it is sold at the maximum speed of 1600 MHz, it is guaranteed to work at that speed or less. For example, a 1600 MHz RAM will work at 1600 MHz or less. That is to say, a 1600 MHz RAM will work at 1333 MHz just fine. Alternatively, to unlock the full potential of your RAM, you can overclock your motherboard.
Is higher MHz RAM better?
Current gen DDR4 modules usually run at 3200MHz. What’s important to remember here is that system RAM is not handling command processes like the CPU does, so while a higher CPU frequency will almost always mean better PC performance, the same may not be the case for high frequency RAM.
How do I check my DDR2 RAM speed?
These both reference and allude to the generation of the RAM and its transfer speed. The number after DDR/PC and before the hyphen refers to the generation: DDR2 is PC2, DDR3 is PC3, DDR4 is PC4, and DDR5 is PC5. The number paired after DDR refers to the number of megatransfers per second (MT/s).
What is DDR2 RAM speed?
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.

What does 667mhz mean?
667mhz is half of 1333mhz, which means that your ram is running at 1333mhz, which is standard. Just go in your bios and change it to 1600mhz, then it will show you are running it at 800mhz, which is the correct speed.
Is higher Mhz better for RAM?
What RAM Mhz do I need?
How fast should RAM be for a gaming PC? Generally, we’d recommend you stick with two DDR4 modules for a dual-channel build, each with a minimum of 3,000MHz clock speed. That should ensure you’re getting the most out of the best CPUs for gaming (opens in new tab).
