I do believe that you have an incompatibility problems. You are using a Patriot 1.5V 32 GB (4 x8 GB) Quad Channel 1333 MHz RAM Product code: PGQ332G1333ELQK on the system which is not compatible or validated with your Intel Desktop Board DH77KC.
The board has four DIMM sockets and supports the following memory features:
- 1.5V DDR3 SDRAM DIMMs with gold plated contacts, with the option to raise the voltage to support higher performance DDR3 SDRAM DIMMs.
- 1.35V Low Voltage DDR3 DIMMs (JEDEC specification)
- Two independent memory channels with interleaved mode support
- Unbuffered, single-sided, or double-sided DIMMs with the following restriction: Does not support double-sided x16 DIMMs.
- 32 GB maximum total system memory (with 4 Gb memory technology).
- Minimum recommended total system memory: 1 GB
- Non-ECC DIMMs
- Serial Presence Detect
- DDR3 1600 MHz, DDR3 1333 MHz, and DDR3 1066 MHz SDRAM DIMMs. Third-generation Intel® Core processors are the only processor family that supports DDR3 1600 MHz DIMMs.
- XMP version 1.3 performance profile support for memory speeds up to 1600 MHz
Please visit the link below that the Patriot Memory is compatible with Intel® X79 chipsets only.
I therefore suggest you to use or test a compatible Memory on your Intel Desktop Board DH77KC its should solve your problem.

I hope its help.
What's going on?
The memory I bought is not compatible with the Intel Desktop Board DH77KC. The 1st support agent from intel means the memory where broken and the 2nd supporter means the memory is wrong / incompatible for DH77KC mainboard because there where certified for X79 chipset mainboards.
But I test both memory (Corsair & Patriot) with no problems in the following mainboards:
Gigabyte GA-990FXA-UD3 rev1.0 (Chipset: AMD 990FX, AMD SB950)
Gigabyte GA-990FXA-UD3 rev1.2 (Chipset: AMD 990FX, AMD SB950)
ASROCK P67 Pro3 (Chipset: Intel P67)
Gigabyte GA-H77-D3H (Chipset: Intel Z77 / Intel H77 Express)
In all 4 mainboard (not x79 chipset) the memories where running well.
So I gave back the DH77KC mainboard where I sold it. This was my first and last mainboard from Intel because all of the mainboard from the other manufacturers are more compatible with different types of memory.
P.S.: The memory support list sucks because 80 - 90 % of the memories tested in Intel Lab you can only by in USA or China. In Europe you can't buy them.
I had a similar problem with Kingston memory, the system would not even POST if I had more than 2 DIMM slots filled. I have the same motherboard.
I eventually solved the problem by installing only 2 memory modules (so the computer would POST and let me get into the BIOS menu). Then, I increased the voltage for the memory to 1.55v (the memory is rated at 1.5 volts). This did the trick and I now have all 4 memory modules installed and working. I have had no stability issues since.
I was told in another forum that increasing memory voltage is a common fix for memory stability problems. Please note that increasing voltage will reduce the lifespan of your memory, but this is negligible since memory generally comes with a lifetime warranty - meaning every other component in your computer likely die before your memory does, even if you give it increased voltage.
