Ok So I just noticed he said 1 hour of 28.7 not 28.9 So I'm guessing 28.9 is some stupid overkill bull**** that probably errors even at stock ?

Hello all,

I'm relatively new to overclocking. I OC'ed a i5 2500k on an older ASUS motherboard a couple years ago. Now I'm on to bigger and better things. This leads me to a few questions I've run into that I would like to have answered before I go changing any multipliers or voltages.

My current rig is utilizing Ripjaws Trident Z 3200mhz 14CL RAM, an i7 6700K CPU and ASUS Maximus Hero VIII Hero motherboard. As the guide said I understand that I need to bump my multiplier to x44 or x45 and set my core voltage to 1.35. The guide doesn't go too much into detail about LLC. Should I leave it on auto, set it manually, set it to adaptive? I'm also a bit confused if Intel SpeedStepping should stay enabled as well as C states and turbo boosting. Also, should I've seen conflicting posts on whether it is better to use XMP or set timings manually. My motherboard has no problem setting the correct timings via XMP, it's under-reporting on the labeled voltage a tiny amount but that is it. My bios reports 1.344 instead of 1.35.

Hope I'm not putting anyone to sleep with my newbie questions. I really want to get deeper into overclocking and optimizing my system but it can be overwhelming trying to learn so much and worrying about messing something up by tampering with the wrong settings.

Thanks!

Both links in main post for prime 95 lead to version 28.9...

Ok I'm going to just make the assumption that 28.9 p95 is just a glitchy overkill piece of junk that I never want to see again. Passed 20 runs of ibt on maximum and 6 hours of x264 16 threads. Going to run my traditional 3-4 hours of p95 27.9 tomorrow and call it stable. 28.9 you can burn in hell for screwing up my day.

Back to stable at your 4.5?

OK so i had the chance to test a 2nd i7 6700k on my gigabyte Gaming 7 motherboard. My orignal i7 6700k was made in Taiwan and needed like 1.40v to run 4.6ghz stable, and 4.7ghz was pretty much unattainable stable, even when just playing with 1.47v. My new i7 6700k was made in Malaysia and i manage to get it stable to 4.8ghz @ 1.42v set in bios, cpu-z shows 1.416 idle on desktop and 1.404 under load. Temps seem good, except for 1 core which seems to hit 91c, the rest all stay under 88c. This is full load. idles around 34c, and i see about 68c when playing games like the witcher 3 and overwatch.

I wanted 4.7ghz, but Ill take the 4.8. still playing around with it, but will most likely stay here. much happier, and seems to show there is definately some variance between chips.

Set Vcore manually at first with your LLC set to 5. Increase Vcore to ensure stability however I recommend staying below 1.4Vish depending on temps. 1.45 is fine if you can handle to temps but you shouldn't need to go higher. Once stable switch to adaptive.

Leave speedsters etc alone no need to change them IMO.

As far as dram voltage that is just the resolution of the sensor if your ram is stable don't worry about it.

All those temps are extremely high. IMO get a water loop either custom or AIO if you are running those voltages. I would back off to 4.7 and lower volts until then.

Thanks, I will see what I can do! Do you think my temps will be find with my goal being 4.4 - 4.6ghz using a Cryorig H7 air cooler? I'm idling now around 28-33C.
post #8450 of 11364
There are a lot of variables that play in such as type of thermal paste, case air flow, fan type, etc etc. only way to know is to try. If I was to guess unless you have a poor chip which unfortunately is a possibility playing the silicon lottery you should be able to hit 4.6 within temps. 4.7-4.8 is when most chips start seeing a voltage wall requiring larger increases of Voltage per .1ghz speed step.
