Skylake Overclocking Guide [With Statistics] - Page 281

Looks dirty lol. Eyeballing the lacklustre DC thread, and I notice only the most rubbish of chips being clocked to 4700mhz are pushing up into the 1.30 to 1.35Vcore range.

SL overclocking looks like a dog (especially given the same old TIM situation), at least from the outside

Are you kidding man?

SL clocks more consistently and notably higher than vanilla haswell, just probably not more than DC. Both are a substantial improvement over vanilla Haswell where people would kill for these OC's.

My 6700k is OVER 20 CELCIUS cooler than my 4700k with the same cooling and vcore - and my 4770k wasn't bad, it was normal. The load that would put my 4770k at 93-95c will not even break 70 on this 6700k.

I admit, I did forget that, but still interesting and on air tongue.gif

And my question still -

Are you guys resetting back to 'AUTO ' on all Cores after OC ? Reason being, is that you will use less voltage with less demanding usage

Well yeah, I'm coming from that DC perspective haha...

I was going to ask Darkwizzie how the temperatures worked out between HW/DC and SL if the same Vcore is applied, but it looks like you've already answered that. I honestly expected slim-to-no changes in voltage-temperature curves, but it looks like I'm well off the mark haha redface.gif

I'm keen to see how all these 1.3X Vcore's play out in the long term. Obviously power saving features are still a thing, so it'll take an understandably long time to see how the chips fair after long periods at that voltage.

Lowered manufacturing process (HW/DC vs SL) + similar voltage (~1.35V) = no fallout? tongue.gif

One reason I am trying to keep my voltages down, Skylake is still new, and so are the m/boards and I personally do not want the chip dying scenario that was going about with the i7-5960X and ...... redface.gif

Well, Intel has them all running 1.3v at stock and 1.4v at stock+turbo. They obviously either think the chips can take those voltages + more or will be replacing chips from all over the world in short order!

Cahe clock does affect performance (period).

Bit off topic but I guess my MSI M7 motherboard doesn't have LLC! Suprising...
how much droop do you see when loading the cpu? Droop is on this voltage rail for a reason (load-change induced transient voltage spikes - happens at a clamped voltage). The V_overshoot at stock voltage has a design limit of 70mV for 10usec... best to run 24/7 with some droop on vcore (table 7-2 in Datasheet Vol1.).

The data in the OP isn't opinion, it's testing results. You're free to post your own test results. If it contradicts with OP in any way, i'm sure it will be looked over.
yeah, I have too. And posted a test result that measures ram/cache performance at the same core clock. The data in the OP is fine, but really does not directly compare apples with apples (redface.gif). Comparing performance numbers at different core frequencies skews the results.
Frankly, fast ram and fast cache - the whole show is just more... "snappy". smile.gif

I agree - if and when i go back to gaming and i do see substantial difference in fps then it will be worth it thumb.gif

Hello

Because of voltage rails cache speed is basically free with Skylake. I'm not sure why one would leave the speed at stock levels regardless of the amount of performance increase seen.
