How to identify computer ram ddr1 ddr2 ddr3, DDR4 Identifying the Computer RAM (Random Access Memory) like DDR1, DDR2, DDR3, and DDR4 physically is not so hard if you follow the steps.

DDR4 is not backward compatible with DDR3 motherboards because the physical design of modules (DIMMs) for DDR4 and DDR3 are different. DDR4 vs DDR3 DIMMs. DDR3 modules use 240 pins and DDR4 DIMMs use 288 pins. Both DDR3 and DDR4 DIMMs are 5¼ inch (133.35 mm) in length but the pins in DDR4 are spaced closer (0.85mm) than DDR4 (1mm). Factory configured 3468 systems often have smaller, less expensive modules. As more memory is required different density and technologies are needed. DIMM type mixing is never recommended. What Dell Vostro 3468 memory speed is supported? DDR3-1600 and DDR4-2666. Why may there be various speeds of Dell Vostro 3468 memory? Physically, a DDR4 module, or dual in-line memory module (DIMM), looks very similar to a DDR3 DIMM. However, DDR4 has 288 pins compared with DDR3’s 240 pins; DDR4 SO-DIMMS have 260 pins instead of 204 in DDR3. The DDR4 key notch is in a different place, and the edge connector looks like a slightly curved “V” to facilitate insertion.

The ram is ddr3, and i found out that ddr3 and ddr4 are physically different, so they wont be able to fit inside the ddr4 memory slots on my motherboard. Is there an existing solution that can conver the ddr3 memory into ddr4 memory so that it can fit in the ddr4 memory slots on my mother board? Thanks in advance. When comparing two models of RAM from the same manufacturer, we found that a pair of 8GB DDR3 Savage sticks (16GB total) clocked to 2400Mhz cost $103.99 on Newegg, while the same pair in DDR4 costs $129.99 — that’s about a 21% increase. That’s not too terrible all things considered, but it’s still more expensive.

1. Distance of Notch
2. Integrated Chip (IC) type

DDR1, DDR2, DDR3, DDR4 is the most using RAM currently in the market.

First of all confirm is it DDR1, DDR2, DDR3, or Different DDR’s SDRAM. keep your DDR chip front-facing as given bellow. here look to the notch each DDR notch distance is different from others DDR. It’s mentioned in the picture.

Distance of Notch

• • Notch Means above cuts Mark on RAM
    • DDR1, DDR2, DDR3 having Single Cut mark on the base of the RAM
  • But you can see the Cut mark (Notch) distance (see below photo)
    • Notch of DDR1 and DDR2 are similar but if you see closely,
      • You can find DDR1 Notch is just above the IC and DDR
      • DDR2 Notch is just far to the IC
    • Notch of DDR3 is different from the other two.

• Integrated Chip (IC)

  • See the Above Photo
    • DDR3 having small and square type IC.
    • DDR2 is just bigger then DDR3 and smaller the DDR1,
    • In this case, too, DDR1 and DDR2 are just a small difference
      • IC in DDR1 are touched both top and bottom of RAM
      • and IC in DDR2 is just center of the RAM

Ddr3 Ram In Ddr4 Slot

• Number of Pins in DDR1, DDR2, DDR3, DDR4

  • DDR1 – 184 Pins
    • DDR2 – 240 Pins
      • DDR3 – 240 Pins
        • DDR4 – 288 Pins

• Voltage of RAM

  • The voltage of RAM cannot be used for the Physical finding of RAM, but it can be used to place the RAM in the Motherboard Slot. (voltage are written in the RAM Slot of Motherboard)
    • DDR1 Volts – 2.5 v
      • DDR 2 Volts – 1.8 v
        • DDR3 Volts – 1.5 v
          • DDR4 Volts – 1.2v
