Can I use DDR3 RAM in DDR2 motherboard?
Can I use DDR3 RAM in DDR2 motherboard?
Although DDR3 and DDR2 are both 240Pin modules, they have different electrical designs, operating voltages and memory slots. Therefore, DDR2 and DDR3 cannot work together on the same motherboard.
Does a DDR2 motherboard support 8GB RAM?
DDR2 DIMMs are neither forward compatible with DDR3 nor backward compatible with DDR. The maximum capacity on commercially available DDR2 DIMMs is 8GB, but chipset support and availability for those DIMMs is sparse and more common 2GB per DIMM are used.
Can I use PC3 RAM in a PC2 motherboard?
No. PC3 is DDR3 ram. PC2 is DDR2 RAM. They are notched differently and if you try to jam one or the other into another slot you could risk damaging your board.
What is the fastest DDR2 RAM?
Corsair Dominator PC2-10000
Corsair seems determined to hold the record for the highest memory speed in production memory. We recently reviewed the highest speed memory available at the time in Corsair Dominator DDR2-1111 (PC2-8888).
What is PC2 on RAM?
PC2- indicates the module uses DDR2 memory; PC- indicates the module uses DDR memory.
What is the difference between PC3 and PC2 RAM?
pc2 = ddr2 and pc3 = ddr3. according to that spec sheet you linked, your system came with 3gig ram, and max’s out on 4gig. it also says vista, but does not mention whether it is 32 or 64 bit. if its 32 bit, you can’t access more than 3.25ish gig of ram.
What do you need to know about DDR memory?
Everything You Need To Know About DDR, DDR2 and DDR3 Memories Memory Real Clock Maximum Theoretical Transfer Rate Memory Module DDR200 100 MHz 1,600 MB/s PC-1600 DDR266 133 MHz 2,133 MB/s PC-2100 DDR333 166 MHz 2,666 MB/s PC-2700 DDR400 200 MHz 3,200 MB/s PC-3200
Can you upgrade from DDR2 to DDR3 memory?
Unless your motherboard supports both DDR2 and DDR3 sockets (only a few do), you cannot upgrade from DDR2 to DDR3 without replacing the motherboard and eventually the CPU (if in your system the memory controller is embedded in the CPU, as with all processors from AMD and Core i7 from Intel). The same thing is valid with DDR and DDR2.
What’s the difference between DDR2 and DDR3 memory?
Clocks ending in 33 and 66 MHz are, in fact, periodic decimal expansions (33.3333 and 66.6666, respectively). DDR3 memories operate at lower voltages compared to DDR2 memories, which in turn operate at lower voltages compared to DDR memories.
Where is the resistive termination located on a DDR memory?
On DDR memories, the necessary resistive termination is located on the motherboard, while on DDR2 and DDR3 memories this termination is located inside the memory chips – a technique called ODT (On-Die Termination). This is done in order to make the signals “cleaner.” In Figure 5, you can see the signal that reaches the memory chip.
