Can we overclock i3's now

[K_A_N_T]

Hey, I was just wondering, with the decoupled blck in the z170 chipset, would it be possible to overclock an i3, a pentium, or even a celeron processor? Maybe even a non-k i5 or i7. The i3 chips would be much more attractive for budget builds if you could squeeze some more gigahertz out of them to help them equal some of the i5's power, and if you could save some money buying a non-k, low-end i5 and still get almost 4 ghz out of it in the end, Skylake would start to look much more enticing to me and possibly many other budget builders.

they wouldnt allow that because then no one would buy a I5

it would cannibalize the low-end i5s so i doubt intel would do that

[TheNeutraliser]

just enable hyperthreading

If I recall correctly, BCLK overclocking is unlocked, yes?

[hsm]

the pentium would have no place in the market if the i3 was overclockable.

What? The pentiums are cheaper than i3s. If you mean the g3258, they are outdated.

[Rolling Potatoe]

Basically yes, fsb overclocking is much better now.

I havent tried it myself yet but ive seen the 6700k at 4,6 with fsb overclocking only I think, 

so it should also work well with lower end stuff.

yup - G3258 is more a toy than a useful CPU - a lot of modern games stutter or refuse to run on it

You don't buy an OCable Pentium as a daily driver. You buy it as a toy.

I got a g3258 as my daily driver and it is great. is a great chip for the price especially at microcenter. I can play GTA V with my gtx 750 ti SC great grated it is on low settings but it still looks great.

the 750 ti can pull off much more than low on gta 5 you know that

This forum could have fucking fooled me on that one.

Before this you must pay extra to have a unlock multiplier so you can OC crap. In the oldschool days you oc via FSB and I think BCLK is basically the FSB. so then yes, you can OC a Core i3?

It's always been unlocked, but it's decoupled from the PCH frequencies on the Skylake platforms so you don't have the same side-effects of messing with it that we did with Haswell. It works well on the 6600K and 6700K, but the locked CPUs aren't for sale yet. We'll find out soon, but I'm personally skeptical Intel is actually going to let this happen the way we're hoping.

Yeh seems like a shot in the dark for them to all of the sudden let people overclock their locked chips lmao. But nonetheless it is worth a shot!

Well the multipliers are still going to be locked. But you could theoretically get a lot out of the BLCK. 140 * 32 is nearly 4500 MHz, and that wouldn't be unrealistic with a 6600K/6700K. I have to assume Intel is going to have something up their sleeve to prevent that.

 

Just a thought: We know the rest of Skylake is targeting either 65 Watt or 35 Watt thermal envelopes. If these chips have correspondingly tight power budgets, they may not have much overclocking headroom regardless of having an adjustable BCLK.

Well it's not unheard of. The Sandy/Ivy bridge QM chips x7xxQM and x8xxQM had a +400MHz OC allowance, and haswell MQ chips had a scaling allowance (47xx +200, 48xx +400, 49xx +600). I don't see why basic OC (still unstable) OC features for locked chips are a problem for the desktop chips, especially if they're limiting their lineup like they did with Broadwell. I mean, nothing is going to beat the ease and more-or-less guaranteed stability of simply bumping multipliers of an unlocked CPU. Not like someone's going to buy a locked i3 or i5 and end up with 4.6GHz like the 6600K can probably easily do.

Increasing volts is not very difficult

Increasing volts is not very difficult

TDP lock has nothing to do with volts. If the chips will not take above their long turbo power limits, then it doesn't matter what you do. I would not put it past intel to limit them to their TDP envelope designs on the lower models.

 

For a good example of CPUs that are supposedly "high end" but TDP limited, check the HQ CPU section of my mobile CPU guide.

I really hope someone tries this. If it works, it should change how people with an adjustable blck look at the product stack.
