All computer systems run differently, speed, bootup, benchmarks, etc.
All components perform differently, two identical packages of a CPU or RAM may not perform the same.
One may overclock higher and require less voltage to do so, it can be the same when running at stock settings.
For RAM, a DRAM or IMC voltage bump can solve instability issues.
The CPU load temp is high even for a stock Intel CPU cooler.
Your Intel CPU spec sheet.
Intel® Core™ i7-2600K Processor
Intels max CPU temp, Tcase (this is the CPU case), is 72.6°C.
Add 5°C for the max CPU core temps, makes your max CPU core temp 77.6°C.
What was the CPU frequency at full load?
Check CPUZ when at full load.
Is turbo enabled?
Have you overclocked anything in your system?
Check that your CPU cooler is firmly attached, you shouldn't be able to turn it.
If it is loose you need to replace the thermal paste.
If you run your system at these high temps you need to consider getting an after market CPU cooler.
