Depending on your motherboard it is most likely because most motherboards can only use one type of ram at a time. So you can only use ddr with more ddr to see more than one stick of ram.

If your motherboard supports ecc sdram memory can you substitute sdram memory that does not support ecc?

Yes you can. There's also an option in the CMOS setup to enable or disable this feature if your motherboard supports it.


If you motherboard supports ecc sdram memory can you substitute sdram memory that does not support ecc?

Depending on the specs of the motherboard, a motherboard that supports ECC SDRAM may support a non-ECC SDRAM module. If a motherboard can support both types, you would have the option to enable or disable the ECC feature in BIOS. Other than the fact that an ECC module has an odd number of chips, there is no other physical difference on the module. They are keyed the same.

It is difficult unless the motherboard supports DDR slots.

If your motherboard supports ecc sdram memory can you subsitute sdram memory that does not support ecc if your motherboard supports buffered sdram memory can you subsitute unbuffered sdram modules?

Depending on the specs of the motherboard, a motherboard that supports ECC SDRAM may support a non-ECC SDRAM module. If a motherboard can support both types, you would have the option to enable or disable the ECC feature in BIOS. Other than the fact that an ECC module has an odd number of chips, there is no other physical difference on the module. They are keyed the same, unlike buffered and unbuffered SDRAM modules. Because of this fact, a motherboard would not be able to support both buffered and unbuffered modules. The motherboard's memory slots must be configured specifically for the buffered or unbuffered memory module. - You can substitute non-ECC memory on an ECC board, and the error-checking feature will be shown disabled in CMOS. Go the manufacturers website of your motherboard and check out the specifications on your motherboard. If it does not say unbuffered memory then it will not accept it. Some motherboards accept both in the same port.

How do you replace sdram into ddr?

In order to upgrade SDRAM with DDR, you will need to replace your motherboard. DDR uses a different slot than SDRAM, so if your motherboard is using SDRAM currently, you will most likely have to replace your motherboard in order to make your system support DDR.

No.


Ddram and sdram can be the same pin because i have old motherboard that i want to change a new oneis it possible to use my old sdram to my new motherboard which is ddram?

No. SDRAM has two notches and DDR SDRAM has only one so besides all the electrical incompatibilities it won't physically fit.

Is it possible to run an AGP card with DDR ram on a motherboard that only supports sdram?

The Accellerated Graphics Port card uses memory completely separate from the motherboard memory. They don't mix. Make sure you use the memory that the AGP card nees in the AGP card, and memory that the motheroboard needs in the motherboard. If you do that, everything will be ok.
