Yes. They are backwards compatible. Even with the installed 800MHz ram It will still only run at 667MHz speeds.
You cannot use DDR2-5300 RAM instead of DDR2-4200 RAM in a system that specifically requires DDR2-4200. While both are DDR2 types, they operate at different speeds, with DDR2-5300 having a higher bandwidth. However, if the motherboard supports DDR2-5300, the faster RAM will downclock to match the lower speed of DDR2-4200. Always check your motherboard specifications for compatibility.
No, you cannot. PC2 is ddr2 type of memory when PC is ddr. Those types are not compatible.
DDR2. Theres several diffent speed DDR modules, exactly what you will need depends on what CPU you are using, but the slowest DDR2 you can use in this motherbaord is 533, and the fastest DDR2 800. 800 is probably the best to use.
Yes
Although it would probably be possible, depending on the chipset used, it would offer poorer performance.
The ASRock G31M-S uses DDR2-667 or DDR2-800 modules. it supports up to 8 GB of RAM using two 4 GB modules.
DDR2 PC2-4200,DDR2 PC2-5300,DDR2 PC2-6400 with a maximum of 1GB per slot (equals 4GB max total system memory)
Unfortunately you can not. DDR and DDR2 have a different pin arrangement and they will never work in each others slots.
Unfortunately not. DDR has a different amount of pins compared to a stick of DDR II. Also the slot position is slightly different. Hope this helps Be Safe Cadishead Computers
No DDR and DDR2 Slots are differant on Motherboard so cant replace each another
No, you can't use same DIMM slots for DDR2 and DDR3 due to different position of the key and interface incapability.
Yes, you can use DDR2 RAM with an Intel Core 2 Quad processor, provided that the motherboard supports DDR2 memory. Most Intel Core 2 Quad processors are compatible with motherboards that have DDR2 slots, so ensure that your motherboard specifications align with the RAM type. However, it's essential to check the specific motherboard documentation for compatible RAM speeds and configurations.
