I set up a quick overclock when I built my PC and then I've fine tuned it once or twice since then. now I've had it a year and it's been a while and more and more next gen games are coming out so I'd like to know what the sweet spot is for an i5-3570k, I've read they each vary slightly in OC capabilities but mine seems to be average, not great and not terrible, from what I've read.

i5-3570k @ 4.3 GHz
1.26v
TDP 77W (never learned what TDP does)
a non-thermal cpu cooler, can find the name in an order history if needed
gigabyte z77-d3h mobo

TDP = Thermal Design Power. It refers to the maximum wattage pull of the CPU (keeping it very simple here) and how much heat it may generate under load. See here for more:

http://en.wikipedia.org/wiki/Thermal_design_power

Optimal OC configs varies from system to system. Airflow (as it relates to operating temperatures) and stable power are major factors in achieving an optimal config for your specific system.

How are you idle and loaded operating temperatures (CPU and GPU)?
What make/model of GPU and PSU are you using?
Other than the CPU, are you OCing the GPU and/or memory?

depending on your cooling solution installed and your smps....i would say 4.8-4.9 should be good (at least for a d3h that is good enough).

any higher than that will require a lot of tinkering around with the cpu voltage and an exotic cooling if you would like to use your pc for long durations.

Start you own thread in the OC section. You'll get more feedback by doing so.

sorry for the late reply, it's been a very hectic month, let's see

How are you idle and loaded operating temperatures (CPU and GPU)?
my idle temperature is 35-45 degrees and my gaming temperature is 60-70 degrees

What make/model of GPU and PSU are you using?
EVGA NVIDIA GeForce GTX 670 GPU
Antec TP-750 Blue TruePower 80+ Bronze 750W PSU
NZXT Havik 140 Desktop Processor Cooler w/ Dual 140mm Fans Cooling
Fractal Design Define R4 with Window Black Pearl Silent ATX Mid Tower Case

Other than the CPU, are you OCing the GPU and/or memory?
GTX 670 GPU clock @ 1123 MHz
GTX 670 memory clock @ 3206 MHz
RAM overclocked @ a safe spot, don't remember the MHz but I can go into bios to check if needed

please I would love to go as close to 5.0 GHz as I can with my setup! I am in Florida heat year round but I usually have an AC on in my room

If I were you, I would try raising the multiplier in baby steps (small increments) and test for stability after each tweak.

Keep in mind that no 2 systems are truly identical and that your personal OC will vary for others.

BTW, I don't recommend OCing main memory (others do). I feel that the performance gained (miniscule typically) is not worth the instability that can arise. I recommend focusing on the CPU and GPU instead.

so you think memory at default instead of "Xtreme 1" profile @ 1333 MHz is better? that's what it is now. I get a crash in WOW when I OC my CPU too much but it says memory.

alright I'll keep tweaking around,
is 77W TDP good?

I did 4.5 GHz @ 1.38 Vcore last night and it was completely stable just too hot, a core hit 91 degrees while playing FC3, then I did 4.5 GHz @ 1.30 Vcore and got one crash, now I'm trying 4.5 GHz @ 1.32 Vcore

is it safe to go beyond 4.5 GHz or am I pushing it?

if I understand it correctly, I want to keep my temps below 70 if possible and below 90 maximum, preferably well below 90, which means tweaking my Vcore to as low as I can get it, along with raising my GHz to its peak stable sweet spot

do I need to change anything besides those 2 settings? I already disabled power saving and set all 4 cores to 45
