People need to start looking at the TIM thing from a different perspective. What I mean with this is Intel has their reasons not to solder. We probably won't find out what those are and we don't have to agree with it but that doesn't matter. What does matter is Intel decided to use paste to achieve the specifications they want. They meet these specifications so it's mission acomplished from Intels perspective - additionally a modeste overclock is very possible without deliding, in some cases if you're lucky even a high one - bonus points from Intels standpoint. Now if you want to push the CPUs way beyond it's factory specs you'll have to go the extra mile and delid, use AIO or a loop and what not. The general misconcemption here is people think they're entitled to CPUs which easily overclock way beyond it's factory specs without any effort. If you buy a car you won't go around and complain it won't go faster than it does and you have to put some effort in to make it go faster than it was supposed to be.
I know it would be easier to oc higher with solder, but that's not what this is about. The CPUs just aren't soldered, that's just how it is. I too would prefer solder but Intel hasn't soldered mainstream CPUs in years and I doubt they won't again unless they feel the need to.
There's three options, someone can accept the situation and take the CPU as it is, oc it as high as it goes or they want to push it and are willing to delid or they can't accept the paste - which is fine, there's always AMD you can buy instead.

When spending $400 on a custom loop and noticing it had no effect at all on temperatures it's a problem. The 3770K rig was the rig I spent $400 on liquid cooling and temps were still hitting 95C due to an ambient of 88C. After de-lidding temps were at 70C with the 88 ambient temp.




I delidded my 6700k that dropped from 95c full load when using Prime with AVX to 65C at full load after delidding. 76C at full load with all fans at 400RPM with an ambient temp of 81F

Intel's response? "Stop overclocking to avoid high temperatures." If they don't want us to overclock then they should remove overclocking avertisiments from their website.

I will be using my 6700K until Intel releases something that has 15% higher IPC or purchasing Zen 2

This step cracks me up: Apply aggressive cooling doh.gif

The socket changes weren't necessary.
A 6700K would work perfectly on a Z68 motherboard.
Intel just seized the opportunity AMD gave them ( with the lack of competition that is ) to milk the consumers and motherboard makers.
This is no hearsay, it's engineering knowledge based.
They could keep using socket 1150 for example.
They however opted to cash in from chipset sales ( which also pleases the motherboard manufacturers since they will be selling more motherboards, imagine how smaller the mobo makers income would be if you could fit a 8700K on the same mobo you bought the 2600K for ).

Suddenly, now that there's competition from AMD, the CPU's appear to be "socket compatible" hue hue hue.

If AMD manages to catch up absolutely in gaming performance as well, there will be a miraculous price drop for their next gen of CPUs, suddenly Intel will "come to reason".

More like suddenly Intel will raise the rebate program payments again. They won't come to reason, they haven't in the last 40 shady years and the fines they get for breaking laws are tiny compared to how much they are willing to pay for exclusivity. They get fined 1 billion for 6 billion payed to DELL for example. Their advantage from illegal practices is far greater than the fines they get.

This time such tactic won't be as effective and interesting for the OEMs.
Ryzen and EPYC are very interesting and great at perf/cost ratios, I'd say impossible to skip on this time.

Given the penalty Alphabet got, Intel wouldn't like to get struck with such a high penalty as well, things are not the way they used to be around anymore.

4C/8T Coffeelake has the same average capacitance as the 6700K. Only thing different between a Skylake 4C/8T is the voltage scaling and maximum clocks. If you set the clocks and voltage the same, it should draw nearly identical power.

i am sure this is not correct but in the ballpark as an example:

say the pins on sky/kaby are spec'd for 0.05amps* whereas CL needs 0.055amps*.

i think @pez alluded to that by willing to compromise OCing . . . no?


*wild guessing!
OT:
to anyone who knows:
so, how much power are those pins rated for?

i may be totally different talk but anyways, remember the 990FX AM3+ socket thing ? AM3+ socket has larger holes than AM3, and according to AMD it was allaged that it helped to dissipate some sort of heat more efficiently from the socket as compared to AM3. I don't remember exactly, I might be wrong though. But it still didn't stop mobo manufacturers to provide BIOS support for FX8150/8350 CPUs. Since the new FX CPUs still had about 939 pins and even the old AM3 socket had 941 or 942 I am forgetting. I remember My old nightmare MSI piece of crappy MOSFET 990FXA-GD70 piece of poo engineering by MSI was still somehow provided support for FX CPUs despite it was AM3 only.

I think CL should work fine as long as Intel do not have another holiday plans for themselves this year.

Indeed. This was what I had in mind when I posted that tongue.gif.

If I can't only OC a 200-300MHz on a z270 vs. 500+ on a z370, I'll be perfectly content with that because I've found a way to extend the life of my current parts. Much like I did going from a dual Kuma to hexa Phenom II years back.

Would you elaborate what you're refering to with "ambient"? Do you live in a sauna?

There's no issue with pin current rating.
You guys are totally ignoring the fact that current motherboards are capable of feeding 7GHz 4c8t Kaby Lakes ( trust me, the current up there is much higher than any forthcoming up to 5GHz clock frequency 6-8-10c processor.

The only reason behind silly socket changes like no tomorrow by Intel is their own greediness.

i understand that and i am sure that would throw some specs out the window.

i would expect intel to adhere to their own specifications.
