I7-4790k over clocking
Processor i7-4790k paired with cooler master hyper 212 x, PSU corsair 600w, GPU msi gtx 750ti, RAM 8gb, M.2 gigabyte g1 sniffer. Should I overclock my processor and GPU...? Temp while using prime95 shows cpu at 55-60°C and GPU at -35°C. If yes, by how much should I increase it?
The outcome largely depends on the luck in obtaining a stable chip.
A range of 4.2 to 4.5 is considered acceptable.
I recommend the following steps:
Clear all components, including RAM, to their default settings.
Set up a stress tester such as OCCT; avoid using prime95 or IBT which create excessive load.
Keep all voltages on auto mode, then slowly increase the multiplier from the standard value to a higher setting.
Perform the stress test with OCCT—it will terminate if temperatures exceed 85°C.
You should likely run out of safe Vcore before hitting thermal limits.
Track Vcore levels; CPU-Z can provide guidance.
A maximum of around 1.3V is advisable.
Once you reach a comfortable multiplier limit, cease further adjustments.
Only use the maximum RAM XMP settings that function at the stock voltage.
Increasing RAM speed for faster performance may actually hinder overclocking.
Higher RAM speeds come with increased latency, which isn't beneficial.

After completion, apply speedstep and adaptive voltage to lower multiplier and Vcore when idle.
I don't understand this part
Overclocking ram to get faster ram speeds may reduce your overclock.
Faster ram is not that helpful since it is accompanied by higher latency.
Here is a study:

When you are done, implement speedstep and adaptive voltage.
That will reduce your multiplier and vcore when there is little to do.
