Can my 16-bit application run with the 4th, 5th, and 6th Generation Intel® Processors?
Note Document 325462; 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 don't support 16-bit components, 16-bit processes, or 16-bit applications
  • 16-bit applications and software aren't 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

Does the Intel® Core™ i7 Desktop Processor support Error Correction Code (ECC) memory?

Intel® Core™ i7 Desktop Processors typically don't support ECC memory. ECC memory is usually used on servers and workstations rather than on desktop platforms mainly because of the price premium of ECC memory and chipset support. Check with your desktop board manufacturer to see if your board has ECC memory enabled.
