Overclocking 6600k - where should I stay?

post #1 of 3
Thread Starter 
Okay so after a while of having 6600k@4.5Ghz perfectly cool and stable I decided to go a bit further. I am mainly CS:GO player where all the FPS magic is done by CPU power of 4 threads.
So I started at 4.6 but I was quite disapointed with Vcore necessity in order to keep it stable. I was unstable even at 1.41V Vcore, which, according to threads i've seen here and else is quite a lot and I was hoping for atleast 4.7. I even turned off XMP but it didnt seem to affect stability at this point.
So I ended up with 4.6@1.43V perfectly stable and quite hot but nothing extreme for air cooler (maxing 74°C at stress test hottest core according to RealTemp, like 65sih at gaming).
Then in one test I've heard that keeping cache ratio 1:1 with CPU ratio may decrease OC capabilites, unfortunately havent time to test it properly yet but i lowered cache ratio to 41 and kept CPU ratio at 46 and lowered the Vcore to 1.41V and it really seems to be better at this point (before i got insta crash after running stress test CPU:OCCT).
Question1: whats more worthit, to keep CPU:CACHE 1:1 or to get as much as possible of both in terms of performance? How importnant is cache performance in gaming?
Question 2: I dont want to stay with 6600k for years, what max vcore would you choose if you knew you will change it within 2 years? I am a bit scared of everything above 1.4V even temperatures are very fine in my opinion and also Intels datasheet says its max vcore is even 1.52V.
Question 3: What is very fine max temperature you would aim to get? (in case i will stick to rather lower vcore, i have a plenty of headroom to make it atleast more silent)

I would like to know you honest view, any discussion regarding better OC results is highly appreciated since I am also curious if increasing SA and I/O voltage or even RAM voltage could help (never touched).

Cheers

1. Cache speed doesn't really matter, except in E-peen contests. You won't notice a difference. I have mine at default (3.9GHz) with my core speed at 4.5GHz.

2. 1.45v would be the maximum I would run 24/7.

3. I would aim for as cool as possible, hitting no more than 80°C under CPU stress tests.

Thanks for your insight. I was more or less the same opinion.
I will decrease the ring ratio back to 39 or 40 and try.
I tried yesterday ring 41 cpu 47 and vcore at max 1.43v, PC was quite stable but - OCCT stress test reported always core 0 error and stopped, atleast no hard crash. I think the 4.7 is near devil.gif
Actually i am quite surprised with thermals. After an hour of OCCT test 1.41V cores were floating around 50ish °C rarely peaking into 60°C.
I think I will try the 1.45V and will check if Noctua can handle this.
