Which RAM is better 667MHz or 800MHz?
Which RAM is better 667MHz or 800MHz?
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 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. It would be better to use two or four dims, as opposed to three.
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 667MHz RAM?
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.
Why is my ram speed 667MHz?
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 DDR2 obsolete?
it’s not made anymore. if you are incredibly lucky you can find some old stock someone still has. or more than likely you’ll have to get it from a used source.
Can I replace DDR2 with DDR3?
Unless the motherboard supports both DDR2 and DDR3, upgrading to DDR3 will not work. You cannot change DDR2 modules for DDR3, they are different technologies and the modules are not compatible with each other. According to Crucial you can upgrade your laptop either to 4GB or to 8GB, depending on the exact model.
Why is my ram speed 667?
Can I replace DDR2 with DDR?
You cannot change DDR2 modules for DDR3, they are different technologies and the modules are not compatible with each other. According to Crucial you can upgrade your laptop either to 4GB or to 8GB, depending on the exact model.
What’s the difference between DDR2 667 and 800Mhz?
DDR2 667 (PC2-5300) = 5.3GB/sec in single channel 10.6GB/sec in dual channel DDR2 800 (PC2-6400) = 12.8GB/sec in single channel 12.8GB/sec in dual channel With respect to dual channel comparison, its a 133MHz difference which translates into 2.2GB/sec gain from upgrading to 800MHz
Which is better DDR2 667 or 1066mhz FSB?
1066MHz FSB = DDR2 667 ( Good ) OR DDR2 533MHz ( Matched but Slow ) decoupling of clocks plus chip timings considerations. You will not see a difference between CAS 5 and CAS 6 memory timings.
Which is better 2.2GB / s or 800MHz?
So the question is the 2.2GB/s gain suggested by the mathematical comparison a noticeable performance boost in practical computing, that its worth going for a fresh 4GB 800MHz set rather than the more straightforward and cheaper “just add another 2GB 667MHZ” option? To give further insights about the motives behind my interest.
What’s the difference between DDR2 266 and 533?
Core 2 Duo FSB 266 (1066 quad pumped), DDR2 266 (rated as 533 because it’s DDR2) is a one-to-one ratio of memory to FSB and is the factory and chipset default.
