overclock i7 3770k to 4.5 ghz
you're new to overclocking and want to boost your i7 3770k processor. you've tried adjusting settings yourself, but it seems you might be making mistakes. you managed to keep the cpu stable at 4.5 ghz, but then you need to set the vcore to auto or manually set it to 1.310. however, under stress testing with prime95, your temps exceed 90 degrees celsius within just 10 minutes. you need guidance on the right bios settings.
or it simply indicates that 4.5 exceeds what your chip can handle, you didn't do anything incorrect.
It looks like this chip doesn't meet expectations, falling short of a 4.5 rating.
Why does that seem bad? It was the generation after Sandy, which could do 4.6-4.8, but it was soldered. Ivy was the first of the non-soldered ones; 4.5 is a stretch from what I remember. I got my 3570k to 4.3, I could have done 4.4, but I wouldn't have expected to reach 4.5.
My i7-3770K operates smoothly at 4.9GHz with a voltage of 1.32v.
My i5-3570k caps at 4.3GHz regardless of settings or voltage, yet it functions well at 4.3GHz with a voltage of 1.114v.
This is the CPU lottery—every processor doesn’t reach identical performance limits.
The Antec kuhlor 620 is a 120mm rad, about 150w efficient.
Your i7 has a 77w TDP and performs normally at average usage.
Prime95 will push CPUs to their maximum under full load, which is peak power, not just TDP.
For an i5, peak power is roughly double the TDP, while an i7 with hyperthreading is around twice that.
This means you’re running a CPU that will exceed its stock limits at 150w under P95 conditions.
With any overclocking, expect temperatures to rise above 70°C and push your cooling solution to its limit.
In summary, P95 performance on an i7 with this cooler will likely drop into the 90s after OC.
Begin by checking Google, Asus ROG forums, etc. The stock voltages on those Ivy boards usually range from 1.2v to 1.25v, but with a modest overclock like 4.3GHz you can achieve a smaller value. Just giving numbers without context won't help.
Review everything about the OC of the 3770k, your motherboard, and general overclocking. Look through forum discussions, search for unclear terms or functions and understand what they do.
Do all this before even modifying your BIOS.
