results in increased performance of both single and multi-threaded applications�
How much faster will my processor run with Intel® Turbo Boost 2.0 Technology
6
?
The maximum frequency of Intel® Turbo Boost Technology 2�0
6
is dependent on the number of active cores� The amount
of time the processor spends in the Intel® Turbo Boost Technology 2�0 state depends on the workload and operating
environment� Any of the following can set the upper limit of Intel® Turbo Boost Technology 2�0 on a given workload:
Number of active cores

Processor temperature
When the processor is operating below these limits and the user’s workload demands additional performance,
the processor frequency will dynamically increase until the upper limit of frequency is reached� Intel® Turbo Boost

DDR4 memory
What is DDR4 memory?
The 4th generation double data rate memory is called DDR4�
Which HP Z Workstations oer DDR4 memory?
The HP ZBook 14u G4, HP ZBook 15u G3/G4, HP ZBook Studio G3/G4, HP ZBook 15 G3/G4, HP ZBook 17 G3/G4, HP Z2 Mini G3,
HP Z240 SFF, HP Z240 Tower, HP Z440, HP Z640, and HP Z840 Workstations all only support DDR4 memory�
Will DDR3 memory work in the HP ZBook G3 or G4, HP Z240, HP Z440, HP Z640, and HP Z840 systems?
No, users will have to transition to DDR4 for the HP ZBook G3 and G4 systems, HP Z240, HP Z440, Z640, and Z840
Workstations� DDR3 and DDR4 memory types cannot be intermixed or installed into systems in which they are not
supported�
What are the advantages of DDR4 memory?
DDR4 memory is moving at 2400 MHz, up from 1866 MHz on DDR3, so potentially, when the system is running at max
capacity, the user could see an increase of up to 28% in speed and higher performance�
