Memory Upgrade Tips
 
  • System is capable of recognizing 4GB of memory. However, due to the 32-bit limitation of MS Windows/Mac OS, Operating System can only utilize 3.25GB of the memory when 2GB + 2GB are installed. Therefore we recommend the configuration of 2GB + 1GB = 3GB for this system. 64-bit windows would not have this limitation.


  • Your HP Business-Desktop-PCs DC7800 only supports memory modules made with a specific type of chip. Should you find what seems to be the exact same memory modules elsewhere for a lower price, it is very possible that the cheaper memory modules will not work in your system. By using Memory-Up's Memory Finder, your selected memory modules are Guaranteed To Work or your money back.<Learn More>

  • Determine which type of user you are and how much memory do you currently have first before buying the new memory modules.<Learn More>

  • Different sizes/speeds of memory module can be used together as long as the specifications meet the system requirements. <Learn More>
 

Model/System Informaion
  HP Business-Desktop-PCs DC7800 Specification
Memory Type: DDR2
Memory Speed: PC2-6400
Chipset: Intel Q35 
Chipset :
A group of chips that together make up a complete computer processing unit, usually on one circuit board (the motherboard). It may include the main central processor, graphics processors, secondary cache memory, and input-output controllers. Memory is one component controlled by the chipset.
Memory Type: Non-ECC Non-Registered,
Memory Slot(s): 4
Max. Memory Per System: 8192MB (8GB)
Max. Memory Per Slot: 2048MB (2GB)
Dual Channel Memory Support: Supported 
Dual Channel :
A development in motherboard and chipset design that allows for increased bandwidth transfer when using two or more memory modules in separate transfer channels. These separate channels allow each module access to the memory controller, increasing throughput bandwidth. It is a good idea to use matched pairs of modules to ensure the best compatibility for dual channel operation.
Tri-Channel Memory Support: Not Supported 
Tri-Channel :
A development in motherboard and chipset design that allows for increased bandwidth transfer when using three or more memory modules in separate transfer channels. These separate channels allow each module access to the memory controller, increasing throughput bandwidth. It is a good idea to use matched three modules to ensure the best compatibility for tri-channel operation.
Install Memory in Pairs: Not Required 
Install in Pairs :
Memory modules must be installed in pairs of matched memory size. This means that if you purchased your computer with 128 MB of memory installed and you want to add another 512 MB of memory, you must remove the two continuity modules and replace them with two 256-MB memory modules.
