Can I Use Ddr4 Ram In Ddr3 Slot

Posted on by

Are DDR3 and DDR4 laptop memory (RAM) compatible? That’s a common question when it comes to memory upgrades. For instance, you bought a new laptop with DDR4 RAM and want to add more memory to it by inserting a DDR3 RAM module from your older laptop. You wonder if that’s possible. Unfortunately, that can’t be done. DDR3 and DDR4 laptop memory are not compatible / interchangeable.

But the default specification says i have 4gb ddr3 l memory so now which is best for 2nd ram slot ddr4-2400 or lpddr3-2133? The processor you have can, you on the other hand cannot. Manufacturers have to choose among the possible RAM types a processor support, for your machine they chose DDR3 and that's the only thing you can put. I’m wondering which slots my RAM should go on Gigabyte b450m ds3h. Manual says: Dual Channel Memory Configuration This motherboard provides four memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity o.

First of all, a DDR3 laptop RAM module can’t physically fit into a DDR4 laptop RAM slot and vice versa. Notches on the connectors of memory sticks are on different places. The same applies to corresponding bumps in the RAM slots on notebook’s motherboards. Also, the number of pins doesn’t match. A DDR3 laptop memory module has 204 pins, whereas DDR4 has 260. Finally, DDR3 memory is a bit shorter than DDR4 – 2.66 versus 2.74 inches.

So, a DDR3 memory module won’t fit in a DDR4 slot…

And a DDR4 stick is incompatible with a DDR3 slot…

Besides the physical differences, DDR3 and DDR4 RAM differ in voltages. DDR3 uses a voltage of 1.5V (or 1.35V for DDR3L variant). DDR4 uses 1.2V. It is more power efficient and generally faster, but doesn’t noticeably improve overall performance nor battery life of notebooks.

Note: If you see “SODIMM” in specs of both DDR3 and DDR4 laptop memory, that doesn’t mean they are compatible. SODIMM only means they are small memory modules commonly used in laptops and some small form factor PCs, as opposed to physically much bigger DIMM memory used in traditional desktop computers. As a side note, DDR3 and DDR4 DIMMs aren’t compatible neither.

No you probably can't. While both PC2 and PC3 memory uses a 240-pin connector, they are keyed differently so they'll only fit in board designed specifically for their type. The notch in the memory chip connector edge will prevent you from connecting the incorrect memory.

Similarly, what is the difference between pc2 and pc3 RAM?

What Slot To Put Ram In

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.

Also Know, can you use pc3l and pc3 RAM together? PC3L RAM will work in a PC3 based system as it will run at the standard voltage and will inter-operate with PC3 RAM within the system. This is the speed of the RAM Clearly DDR3-1600 is able to run faster than DDR-1333. You can use the faster RAM, but, you really won't see a sizable difference.

In respect to this, can you put ddr3 RAM in a ddr2 slot?

2 Answers. no - DDR2 and DDR3 are not compatible nor interchangeable. aside from electrical differences (voltage, signal timing etc) the SO-DIMM modules should be keyed differently, additionally I think DDR2 SO-DIMMs are 200 pin whereas DDR3 are 204 pin, they shouldn't fit in same slots.

Can I use 4gb and 8gb RAM together?

Can You Use Ddr4 Ram In Ddr3 Slots

There are chips which are 4GB and 8GB, in dual channel mode this will not work. But you would still get 12GB total only a little slower. Sometimes you will have to swap the RAM slots since the detection has bugs. IE you can either use the 4GB RAM or the 8GB RAM but not both at the same time.
