HP-COMPAQ Z640 Upgrade
Memory Configuration
- The maximal ram memory expansion is512GB ram.
- For memory upgrade there are pro CPU 4 DIMM-Speichersteckplätze ram slots.
We recommend for your a maximum upgrade with 512GB
Our maximum memory specifications may differ from those of the manufacturer as they may be obsolete. New memory technologies or bios or software patches make this possible with the same performance and stability. A system upgrade is recommended if you are working with several memory-intensive programs at the same time. At least 1 or 2GB of memory should be installed.
Important information about your system memory (RAM)
Your system supports only memory modules with selected memory chips. If you think you have found a store for a lower price elsewhere, then it is possible that the cheaper memory chip will not work.
or you get your money back!
