512 SDR. DDR2 is better, but more the memory better it is for your PC, irrespective of the memory technology. You have a point there but considering the current trends, i will prefer the DDR because sdram is being replaced with ddr. Especially if you planning to buy a new mother board, most MoBo's nowadays are of ddr. But speed and capability is better than having plenty of ram. It is with the speed of access not only the space. Besides, it's better to consider efficiency, right?
That means 256 megabytes of RAM that connects to the rest of your computer through the DDR interface.
512 is twice the load of 256
ddr ram is better and faster
Pc1 varies from 256 mb to 1 gb while pc2 varies from 512 mb to 2 gb Pc2 chips are more modified and smaller than pc1
It may or may not support 512 MB DDR RAM. Coz in market only 512 DDR 400Mhz is available, while 845GL supports upto DDR266 MHz. Incase if you have 512DDR400 MHz RAM also, you can install it. It will not do any harm to the system, but it will work at speed of DDR266MHz.... Prakash
If the motherboard supports both DDR and SDR RAM, it is almost always a better idea to go with DDR RAM
Two RAMs of 128 is no better than having straight 256 RAM, because even though you are dividing the RAM up it still equals up to 256 RAM. This means that having two 128 RAMs will work just the same as using one 256 RAM.
No, the slots for DDR2 RAM is different from the DDR RAM. You cannot use DDR RAM with DDR2 slot.
Ram bus DR and DDR, Ram bus DR is alot faster than DDR but 2x as expensive.
Yes it can be added, but sometimes 512 MB RAM may be treated as 256 MB RAM as the slots on which they areplaced have the same priorities.It is always recommended to use RAMs with same memory spaceor a single RAM amounting to the sum of RAMs is best.
ram doesn't use a cable, but sd and ddr are not compatible
No you have to change the whole system build to change from DDR to SD or SD to DDR.
RAM stands for Random Access Memory, and usually comes in sizes in multiples of 256, 512, 1024, etc. Sizes are either in megabytes or gigabytes.
SDRAM is a type of RAM. There are other types of RAM also: DDR, DDR-2, FBRAM, RDRAM...
There is two types. There is DDR notebook RAM and there is DDR desktop ram. They can't be used vin each other (notebook RAM can't be used in a desktop) unless (in rare circumstances) you happen to have a notebook ram port on your desktop's motherboard. But no, DDR is a technology. Both desktops and notebooks support this technology because there is notebook DDR and desktop DDR. but notebook DDR can't be put in desktop DDR and vice versa.
Basically, it is a type of Random Access Memory (RAM) slot, that supports Double Data Rate (DDR) RAM. DDR RAM is said to be twice as fast as Synchronous Dynamic (SD) RAM.
It is possible to use pc3200 ddr ram in a PC designed for pc2700 ddr ram, but the pc3200 ram will only run at pc2700. If you want to fully exploit the pc3200 ram then you will have to buy a motherboard that will be able to support a speed equal to pc3200 or greater.
Add another 256 mb memory card if you have a second slot on the mother board. IF you have only a single slot, then a new 512 mb memory card will have to replace the present 256 mb card. Make certain that your PC will allow this memory upgrade - some older machines have a maximum number for how much RAM it can handle.
That's what a "DDR" slot is. "DDR1" is a retroactive name applied to the first DDR standard after DDR2 RAM came out.
ddr ram 3
ddr 1 ram till 2gbram
DDR is double data rate. RAM is random access memory.
