Are there any new chassis requirements for the Intel® Core™ i7 Desktop Processor platform?

No, there are no new chassis requirements for the Intel® Core™ i7 Desktop Processor platform. We highly recommend using a Thermally Advantaged Chassis (TAC).

Can my 16-bit application run with the 4th, 5th, and 6th Generation Intel® Processors?
Note See document 325462, the Intel® 64-bit and IA-32 Intel® Architectures Software Developer’s Manual.
Section 21.2, Performance:
Always use 32-bit code segments when possible. They run much faster than 16-bit code segments on P6 family Processors, and somewhat faster on earlier IA-32 Processors.
 
  • 64-bit operating systems do not support 16-bit components, 16-bit processes, or 16-bit applications
  • 16-bit applications and software are not validated on 4th Generation Intel® Processor families
  • 16-bit may run on 32-bit operating systems, but it's not optimized for 32-bit OS
  • Consult with your software vendor for a 32-bit or 64-bit version to use with the newer hardware and operating system.

Integration

Where can I find processor installation instructions?

Visit the Intel® Processor Installation Support Center. Get more information on installation and socket integration.

What thermal solution should I use for the Intel® Core™ i7-7700K and i7-6700K Processors?

The Intel® Core™ i7-7700K and i7-6700K Processors require a thermal solution for a 130 W Processor Thermal Design Power (TDP). These Processors have a thermal envelope of 130 W and a power consumption of 91 W and 95 W respectively.

Can I update my Intel® Core™ i7 Desktop Processor?

It depends. First you must check that the socket of your desktop board supports your processor package type. You can get this information from your desktop board manufacturer.

Once you find the model number of your desktop board, visit the appropriate support page on the manufacturer support site. The site typically lists supported processors for your board. Use the Intel® Desktop Compatibility Tool to see if your board supports your new processor.
