Dell Inspiron 1564 8GB, Memory fails to upgrade

I have a Dell Inspiron 1564 and I am trying to upgrade the memory to 8GB.  I bought two KTD-L3CL/4G.  It seems to meet all the specs, but when I try to install it I get a message from windows that it can't restart and needs to be repaired.  If I put the old memory back in, it works.  is there something special I have to do to upgrade this memory?  I thought you just shut down windows, pull the battery, unplug, the replace and start back up.....

If I look in Setup at the start, it shows 8GB memory.  The Kingston page says KTD-L3C/4G, no reference to the CL, just the C.  Is there a big difference?  I am using Windows 7 Home version.

RE: Dell Inspiron 1564 8GB, Memory fails to upgrade

Below are the memory specs and configuration information on the Inspiron 1564.

Memory

The Inspiron™ 1564 system supports dual-channel DDR3 SDRAM with memory speeds of 1066 MHz. At 1066 MHz, this memory offers a significant increase of memory performance over previous platforms.

  • The memory solution is implemented in a dual-channel configuration, allowing the system to have twice the memory bandwidthwhile using the same memory technology.
  • Memory modules must be installed as a perfectly matched pair to take advantage of the dual-channel memory bus. If not a matched pair, the system's memory bus operates in a single-channel configuration.

Memory Configuration

Inspiron™ 1564 has two user-accessible SODIMM sockets, both slots can be accessed after removing the base cover. Basically, when both DIMM connectors are populated, the system has optimum dual-channel performance unless channels A and B have different amounts of memory.

Inspiron™ 1564 DIMM Configuration
Slot ASlot BTotal Memory
1024 MB None 1024 MB
1024 MB 1024 MB 2048 MB
2048 MB 1024 MB 3072 MB
2048 MB 2048 MB 4096 MB
4096 MB 1024 MB 5120 MB
4096 MB 2048 MB 6144 MB
4096 MB 3072 MB 7168 MB
4096 MB 4096 MB 8192 MB

4 GB Memory Barrier

The Inspiron™ 1564 system supports a maximum of 8 GB of memory. The Windows® XP as well as 32-bit versions of Windows Vista can only use a maximum of 4 GB of address space. However, the amount of memory available to the operating system is less than 4 GB. Certain components within the computer require memory address space in the 4 GB range. Any memory address space reserved for these components cannot be used by the operating system.

A NOTE indicates important information that helps you make better use of your computer. NOTE:

This is a limitation of a 32-bit architecture: the system can only address 4 GB of allocated memory. Allocated memory is made up of physical RAM and any I/O space needed by devices. Normally this is not a problem, but when a system has 4 GB of physical memory, the memory addresses needed to map RAM overlap the space needed for the I/O devices. In this case the need for I/O space takes precedence, and the amount of RAM visible to the operating system is limited to 4 GB minus the I/O allocation.

RE: Dell Inspiron 1564 8GB, Memory fails to upgrade

Hello,


I am having the same problem (Windows errors/won't load/pc restarts) with a Dell Inspiron 1564 and one Kingston KVR16LS11/4. It's specification is:

Specs: DDR3L-1600Mhz PC3L-12800 • CL=11 • Unbuffered • NON-ECC • DDR3L-1600 • 1.35V

Your description above says PC3-8500 1066Mhz.

Usually faster RAM will work at slower speeds and even the Crucial website says the memory I bought is compatible with the Dell Inspiron 1564:

http://uk.crucial.com/gbr/en/compatible-upgrade-for/Dell/inspiron-15-%281564%29

You can't buy PC3-8500 1066MHz memory any more.

The Kingston KTD-L3CL/4G memory Steverhnm bought above is also PC3L-12800 1600Mhz.

Is the Dell Inspiron 1564 only compatible with PC3-8500 1066MHz memory?


Thank you
