OC a i7-6700 non K sku?

[SomePurpleRandom]

I'm thinking about upgrading to Skylake and I want to be able to overclock it and since you can overclock non K Skylake CPU's i want to know if I can overclock i7 6700 5Ghz and up with custom water cooling loop. I plan on using ASRock Fatal1ty Z170 Gaming K4 ATX LGA1151 Motherboard. I haven't really been paying attention at all with Skylake but I'm getting more interested so I don't really know. Thanks.

just buy the 6700k and overclock the proper way

its not much more expensive

You can't do that on all mobos. Only some motherboards can OC non K cpu's and it's a risk since non K cpu's are most likely worse than K chips quality wise.

your not going to get up to 5ghz on a non k processor i dont even think you can get up to 5ghz on the unlocked version according to annandtech. it starts to get unstable at 4.8ghz

not happening lol.

If you have enough money for z170 and a custom loop, get a 6700k.

 

'Cause you 'ain't 'gettin' 5gH'z on 'non 'K' 'SKU' k?

Your chances of a 24/7 5GHz OC on any Intel chip since Ivy is extremely low. 4.5-4.8 would be a reasonable goal for Skylake. More results/databases for non-k SKU OC's need to be established before anyone could give you odds. I'd recommend checking OCN.

No one can promise overclocking results. You're usually limited by what the chip can do long before temperatures actually stop you from going further. Your 6700 may not reach 5 GHz no matter how much cooling it has.

 

Assuming that board got a BIOS update to enable overclocking locked processors, you should be able to overclock. We just can't tell you how well you'll do with it.

I don't know about non-K (normal SKU's) but i can say without a doubt that the T sku's are binned extremely high. Very low voltage leak from my personal tests on a 6600T with a 66.7% overclock (166.7BCLK). Now, I could have gotten lucky on my bin i guess, but i've also seen 6100T's reach extremely high clocks vs their normal counterparts. 

 

As for @SomePurpleRandom: Overclocking non-K CPU's is not all that it's cracked up to be. I see it more as a way to get more price:performance out of budget Pentiums, i3's, and i5's. If you are investing in an i7, i would just invest in a K series CPU to save you from the following headaches:

 

1. Overclocking Non-K CPU's disables C states. This means power saving features are gone.

2. Overclocking Non-K CPU's disables the iGPU. This means you lose the ability to use it for Quicksync, or as a multi-monitor setup. You have to use a dGPU.

3. Overclocking Non-K CPU's disables AVX. This means your scores in benchmarks will actually get lower as you overclock, and you lose raw compute performance.

4. Overclocking Non-K CPU's cuts the L1 cache speed by 75%. This will also have a huge impact on benchmark scores. 

 

These are the caveats most reviewers tend to ignore, that can actually impact your outlook on whether or not its worth it to overclock a non-K CPU. If you are a benchmark junkie that wants his name on leaderboards, you will not have a good time. If you fold GROMACS, the loss of AVX will leave a bad taste in your mouth. If you use Quicksync, or need your iGPU for multi monitor setups, an overclocked non-K CPU will completely remove your ability to use them. If you leave your PC on 24/7, and care about sleeping states, then you will not like knowing that your PC is unable to use its C states. 

 

If after all of that, you are still wanting to overclock with a non-K CPU, then its entirely up to you. After overclocking this 6600T, i can easily say that i would probably spend the extra bit of cash to get a K series CPU IF i was using a non-ITX build. So far, this 6600T overclocked to 4.5ghz is not passing 74C under Prime95 with an ITX cooler, in an ITX case. Easily the best investment I have ever made as an ITX user.

K or non K the chance of 5ghz is low unless over voltaging

When u oc non K. Disabled turbo boost manually

Then increase bclk and put the vcore at which ever amount u desire. After u get a stable oc then oc the ram back to somewhere close to it original speed or beyond if desire to

You can't do that on all mobos. Only some motherboards can OC non K cpu's and it's a risk since non K cpu's are most likely worse than K chips quality wise.

Non K is not worse than K

They the same and the silicon lottery is what decide if u got a binned chip or not. Saying non K is worse is like saying all other intel locked cpus is trash. If they are worse then there would have been qc issues

It just one is a locked down and the other one is not. Try to oc the non K has some trade off had to be made

Stop spouting nonsense

The silicon lottery isn't all luck… Intel is going to sell the best yield as K-series products. It wouldn't be very efficient to let their best-performing chips go as locked products intended never to be overclocked.

Basically all of this. Make up ur decision

Get K or non K depend on you. You want to try bclk or multipler the K can do it all and it just if u want to spend more or not

The T series (at least, in my personal experience) seems to be the exception to this rule. I believe they are binned highly to prevent voltage leak, because they have to hit that TDP window, and they manage to do so at much lower voltages. I know my 6600T is an easy overclocker, and it seems to be just as capable as any 6600K that i've seen so far. IMC is strong enough to run my memory at 3200mhz CL15-15-15-30-CR1 still, and it is completely stable under both Linpack and Prime95 loads at the following speeds:

 

4.050ghz = 1.3 vcore 

4320ghz = 1.34 vcore

4.5ghz = 1.37 vcore

 

That being said, i don't know what the average 6600k can hit, and at what voltages, but I don't feel like my processor being a T series is hindering the OC at all. If anything, my board is holding me back. I cannot post beyond 170BCLK. If i go 170.1, it fails to post. No amount of voltage changes this.

Right, of course. The T series are sold specifically on their power efficiency so of course they're probably binning those as well. I didn't mean to exclude those, I just don't typically think of them.

To be fair, overclocking the T series is not something a normal person would even think of doing. I was just building a sub 4L ITX case, and decided to go with the 6600T (without intending to OC it) and since my platform and board support it, i decided to give it a go anyways. Very impressed with it so far though.
