i7-4790k build, trying out overclocking, need 5 way optimization help.

Maxz84 · Jan 11, 2015

My system-
i7-4790K
z97
780
750 w psu

in 5 way optimization:
formula for performance (not sure if auto is better?)
tpu: said 1.35 i made it 1.25
fan: 339-1885
Max temp: said 86c
Temp while benchmark reached 70c ( Is this bad) DO i need to get better fan system?

Can i make the score on the benchmark better? If so, how?
How do i know how much i am overclocking my cpu?
What other general things do I need to do to overclock or have better performance and get thje most out of this build?

If i missed any info that you need, please, please ask me.

You should become familiar with some overclocking guides on your chip, as auto settings aren't generally great for overclocking

I would download the latest versions of realtemp, hwinfo64, and cpu-z.

Realtemp is for monitoring core temperature and will also show your clockspeed.

Cpu-z is good for some general info, like ram speed and timings, cpu vid, and clock speed

HWinfo64(my favorite of the bunch) will show lots of info on temperature as well current cpu vcore and other voltage values that cpu-z and other programs do not

sportsfanboy :

What should i be looking for in terms of increasing the voltage and clock speed that is still safe temperature wise and damage wise. Whats a good temp to have, and matching performance. Where do i actually see the results when testing (benchmarking?) and what is best for benchmarking as well?

Thanks, im still new.

sorry for the late reply, Ive bee busy. cinebench r15 is good for testing cpu speed increases. You can bench at stock and after overclocking for comparison.

The general rule of thumb is to stay around 1.3 vcore and below for long term operation. 1.3 as the upper end, provided you have the cooling to handle it. I run mine under 1.25 for 4.7 ghz, but every chip is different. Temperature shoulkd be 80c (core temperature) and under while at 100 percent load.

You can load test to 100% with programs like prime95 27.9, make sure you enable "round off checking" in options before you run the benchmark. I personally use blend, as it uses ram and cpu resources to simulate a more realistic load on the computer. Also don't use anything later then version 27.9, as the test will jack your temperature too high for most air cooling and overclocks.

as far as clock speed goes, you'll just have to test and see how it goes. Most 4790's are jitting 4.5-4.6 and decent cooling and around 1.25 vcore or under. Some howevr, repoprting 4.5- 4.6 with almost 1.3 vcore, so it's the luck of the draw to some degree.

I would try putting the cpu multi to 4.6, enable c-states, and manually set 1.25 in bios as vcore. Try 1.2 cache, and 1.85 input voltage. After testing you can work the voltage down or up accordingly. Leave the cache multi at 40x until your overclock is stable.

Set xmp for your memory, or manually enter stock volts, timing and frequency.

This is what I have at the moment and ill be running some tests now. Let me know if you see anything i should mess with.

This is what i set it to before testing and i did the first test (no ram) and get temps 87-89c.
Is my cooling bad? I have: http://www.amazon.com/Cooler-Master-Hyper-212-RR-212E-20PK-R2/dp/B005O65JXI/ref=zg_bs_11036281_1
But im thinking about getting the big noctua. thoughts?

Also In the top right of the pic, do i need to click group tuning?
