How to Determine Memory Upgrades for Your Dell Precision Mobile M4800 / M6800 Portable Computer

How to Determine Memory Upgrades for Your Dell Precision Mobile M4800 / M6800 Portable Computer



Identify Compatible Memory Configurations for Your Processor

When you upgrade the memory on your Dell Precision M4800 or M6800 mobile workstation, the processor installed on your computer will determine the type of upgrades that can be made.

Once you identify the processor, refer to the compatible memory configurations below to make sure that your upgrade will be successful.

To identify your processor:

  1. Click Start.
  2. Point to Control Panel.
  3. Click System.
  4. Under System, view the model and speed of the processor installed on your computer.
  5. Use the tables in section 2 below to identify compatible memory configurations for your processor.

Dual Core Processors
Intel Core i5-4300M, 2.6 GHz,37W
Intel Core i5-4300M, 2.6 GHz,37W
Intel Core i5-4200M, 2.5 GHz,37W
Intel Core i7-4600M, 2.9 GHz,37W

Quad Core Processors:
Intel Core i7-4700MQ, 2.4 GHz, 47W
Intel Core i7-4900MQ, 2.8 GHz ,47W
Intel Core i7-4910MQ, 2.9 GHz ,47W
Intel Core i7-4930MX, 3.0 GHz, 57W
Intel Core i7-4940MX, 3.1 GHz, 57W
Intel Core i7-4800MQ, 2.7 GHz, 47W
Intel Core i7-4810MQ, 2.8 GHz, 47W

If your computer was shipped with an Intel CoreTM i5 or Dual Core i7 processor, the maximum memory is 16GB, configured by inserting 8GB memory modules into the two SoDIMM slots in the bottom of your computer.

Note: Only the bottom DIMM slots (Memory Slots A & B) are functional when Intel Core i5 or Dual Core i7 processors are installed.

The Precision M4800 & M6800 systems utilize the Intel 4th Generation processors that require memory SoDIMMs known as DDR3-Low Voltage or "DDR3L". Systems utilizing this generation of processors are not backward compatible with regular DDR3 memory modules (Figure 1). If a DDR3 SoDIMM memory module is inserted into the system, the system will not complete Power On Self Test (POST).

If your computer is equipped with an Intel CoreTM i5 or Dual Core i7 processor, the maximum memory is 16GB, configured by inserting 8GB memory modules into the two SoDIMM slots in the bottom of your computer. 1866 MHz SoDIMM configurations are limited to a maximum of 8GB (2 x 4 GB).

Note: Only the bottom SoDIMM slots (Memory Slots A & B) are functional when Intel Core i5 or Dual Core i7 processors are installed.

Compatible memory configurations for dual core processors

Total Memory Number of Modules Frequency and Speed Memory Slots
2GB 1 SoDIMM DDR3L - 1600MHz Slot A
4GB 2 SoDIMM DDR3L - 1600MHz Slots A & B
8GB 2 SoDIMM DDR3L - 1600MHz Slots A & B
16GB 2 SoDIMM DDR3L - 1600MHz Slots A & B
4GB 2 SoDIMM DDR3L - 1866MHz Slots A & B
8GB 2 SoDIMM DDR3L - 1866MHz Slots A & B

Quad Core Processors
Intel Core i7-4700MQ, 2.4 GHz, 47W
Intel Core i7-4900MQ, 2.8 GHz ,47W
Intel Core i7-4910MQ, 2.9 GHz ,47W
Intel Core i7-4930MX, 3.0 GHz, 57W
Intel Core i7-4940MX, 3.1 GHz, 57W
Intel Core i7-4800MQ, 2.7 GHz, 47W
Intel Core i7-4810MQ, 2.8 GHz, 47W

If your computer is equipped with an Intel Core i7 Quad Core or i7 Quad Extreme processor, the maximum memory is 32GB @ 1600 MHz, configured by inserting 8GB memory modules into the two SoDIMM slots underneath the keyboard and the two SoDIMM slots in the bottom of your computer. 1866 MHz SoDIMM configurations are limited to a maximum of 16GB (4 x 4 GB).

Note: For 2 SoDIMM configurations, use only the bottom memory slots (Memory Slots A & B). Dell tested configurations were limited to matching memory module configurations.

Compatible memory configurations for quad core processors

Total Memory Number of Modules Frequency and Speed Memory Slots
2GB 1 SoDIMM DDR3L - 1600MHz Slot A
4GB 2 SoDIMM DDR3L - 1600MHz Slots A & B
8GB 2 SoDIMM DDR3L - 1600MHz Slots A & B
8GB 4 SoDIMM DDR3L - 1600MHz Slots A, B, C & D
16GB 2 SoDIMM DDR3L - 1600MHz Slots A & B
16GB 4 SoDIMM DDR3L - 1600MHz Slots A, B, C & D
32GB 4 SoDIMM DDR3L - 1600MHz Slots A, B, C & D
4GB 2 SoDIMM DDR3L - 1866MHz Slots A & B
8GB 4 SoDIMM DDR3L - 1866MHz Slots A, B, C & D
16GB 4 SoDIMM DDR3L - 1866MHz Slots A, B, C & D
Note: Mixing of memory module sizes between top and bottom memory slots (example: 2 x 8 GB in bottom (Memory Slots A & B), 2 x 4 GB in top (Memory Slots C & D) = 24 GB) IS NOT a Dell SUPPORTED configuration in these models.
