How do I know a DDR 2 2 GB 800 GHz is not compatible to an ASROCK motherboard? I already have in my desktop a DDR 2 1GB but less GHz.
Compatible DDR with the motherboard
Â
Hello.
Please post your ASRock motherboard's model number so we can help you better.
For now, I will assume that (since you mentioned that you already have a DDR2 SDRAM installed) your motherboard supports DDR2.
You problem now is you are not sure if a DDR2 800 SDRAM will have a conflict with your lower speed DDR2. Â The answer is it will not have a conflict. Â DDR2 SDRAM of different speeds can operate together. Â What will happen though is the faster memory module will operate at the frequency of the slowest module. Â So if your current DDR2 is running at 667 MHz, the DDR2 800 MHz RAM will operate at DDR2 667 MHz as well.
Compatible DDR with the motherboard
I don’t think you will have a problem if you want to install a DDR2 RAM module on your motherboard. If your motherboard supports DDR2 memory modules, you can use any DDR2 type memory modules. As long as it is DDR2 type, it will be compatible. Memory modules have differences that will not allow you to use them on different motherboards.
It is the motherboard that defines what type of memory module is to be used. Memory modules have specific notches that will not fit an incorrect motherboard. There are different kinds of DDR memory modules. They are DDR1, DDR2, DDR3, and DDR4. DDR1 is the oldest and I think is now obsolete type of memory module used in the days of Pentium 4 processors.
It is still available on few stores but is no longer being manufactured, I think, since the majority of the computer stores I’ve asked don’t have it and they keep telling me that it is already obsolete. Though you may not find it in your local computer store but definitely you will find it in many online stores like eBay. DDR2 and later are available in the local market.
For a short background, the DDR2 RAM or SDRAM is a double data rate synchronous dynamic random access memory. DDR2 means Double Data Rate 2 and SDRAM is for Synchronous Dynamic Random Access Memory. This is the next version after the original DDR SDRAM or DDR1 SDRAM. It is followed by DDR3 which was released in 2007 and the latest DDR4.
