Is DDR3L and DDR3 interchangeable?

Is DDR3L and DDR3 interchangeable?

DDR3L is pin-compatible with DDR3. DDR3L is a dual voltage capable memory SoDIMM, which supports operation at both 1.5 V and 1.35 V.

What is ZQ calibration in DDR?

ZQ calibration is a process that tunes the DRAM and ESDCTL I/O pad output drivers (drive strength) and ODT values across changes in process, voltage, and temperature. There are two instances where ZQ calibration is performed: on the i. MX53 (DDR pads) and on the DDR device.

Can I install DDR3L ram on a DDR3 motherboard?

DDR3L modules are backwards compatible with DDR3 by design. Manufacturers use the same integrated circuits for DDR3 and DDR3L. The highest quality ICs are tested for operating at 1.35 volts and are branded as DDR3L if they run properly. yes it is correct, that they should use the same Chips.

What is DDR prefetch?

To double the data rate, DDR SDRAM uses a technique called prefetching to transfer two bits from the memory cell array to the I/O buffer in two separate pipelines. This technique, known as double transition clocking, delivers twice the bandwidth of SDRAM without increasing the clock frequency.

What is DDR PHY interface?

The DDR PHY Interface (DFI) is used in several consumer electronics devices including smart phones. DFI is an interface protocol that defines signals, timing, and programmable parameters required to transfer control information and data to and from the DRAM devices, and between MC (Micro Controller) and PHY.

Can I use DDR3L RAM in DDR3 slot?

DDR3L modules are backwards compatible with DDR3 by design. Manufacturers use the same integrated circuits for DDR3 and DDR3L. The highest quality ICs are tested for operating at 1.35 volts and are branded as DDR3L if they run properly. Other than that, there’s no difference between them.

Is DDR3 compatible with DDR2?

DDR3 is not backwards compatible with DDR2. While both types of modules have similar numbers of pins, the notches in the PCB are in different locations. In other words, a DDR3 module cannot be placed in a DDR2 memory socket, and vice-versa.

How do I know if my RAM is DDR3L?

1 Answer. DDR3L can run on both 1.35 V and 1.5 V, while DDR3 runs only on 1.5 V. If CPU-Z reports that memory runs on 1.35 V, that means that you have DDR3L memory. Also, PC3L is synonym for DDR3L.
