Not to mention I stress test with x264 which is real world load temps.

There was this guy at OCN in I guess the delidding thread where he posted an entire convo with an Intel Rep of RMA'ing a delidded chip through the tuning plan. The rep said that all they need is the IHS placed back the way it was and they would consider it. It was sometime back, so you wont necessarily lose your tuning plan.

Yeah... The guy with the 5.0 chip doesn't know what he's talking about...

LOL, having a good chip doesn't serve as being a genius in overclocking knowledge. Oh I forgot, that's what people think these days.

They would consider it. I'm not willing to risk a 340 dollar investment on someone having a good or bad day at work.

He has a good chip, he's a good guy, and he knows what he's talking about. His chip is a golden one, but he knows Haswell fairly well and has proven it. You, on the other hand, have not really proven much with what you say in here.

That's not the point, the point was that it could be done, whereas you dismissed it without searching it up.

Nothing relates to anything of what you just mentioned to the title of this thread. Just because he's a good guy and has posted a few unverified values of how 'just his chip' behaves, grants him proof?

I really don't think so. Talking about proof, before I started opening my mouth to actually help others, I've been running a hypothesis with Haswell and have even posted from time to time. Too bad you never noticed it.

Intel TIM may not be up with the liquid metal TIM, but it's good paste as far as paste TIM goes, it is comparable to gelid extreme, mx4, etc.

Unless you mean in the sense that all paste TIM is crap compared to liquid metal, intel's stuff would be lumped in then.

Possibly. But that Vcore I had 1.95 VCCIN, I was rock solid stable.

You can test whether you need more or less VCCIN by seeing average time till bsod at x264.

Hell yes. Absolutely yes.

For right now, Darkwizzie, could you add my result to the list? I'll get it changed later when I have a better stress test result. Going to test with 1.8 VRIN in about 5 minutes.

Username: Shanenanigans
CPU Model: 4670k
Core Multiplier: 45x
CPU VID: 1.255
Vcore: 1.272v
Input Voltage: 1.9v
Uncore Multiplier: 35x
Uncore Voltage: 1.15v
Cooling Solution: Cooler Master Hyper 212X
Stability Test: IBT 10 runs - High
Batch Number: 314
Ram Speed: XMP 1600 - 9-9-9-27-1T

Notes :

Vcore is 1.284v when stressing with AVX, ie IBT. Full batch is L314B297. I've looked on the internet for this particular batch and I couldn't find results. And it looks like the thermal threshold for the Hyper 212X is *surprise surprise* 1.284v. Temps hit about 93-94C while IBT stressing.

 

You have been charted.

Well there you go.

43 uncore from my experience you should manually tune the voltage. Anything above x41, x42.

I meant to even compare it with the conventional MX4, the MX4 is a lot better.

How can dry TIM even be a good transfer medium of heat? I know it can't. Again, the reason why stock Tim's on Intel's stock sinks dry up after a year or so, making it over heat. This honestly is nothing new.
post #5257 of 19637
It does dry out over time & not as good then, this is true. Other pastes can dry out as well but intel makes it difficult to get at that under-IHS stuff.
Intel TIM was tested in a TIM test a couple years back & was up there with the best performers.

Some guys have delidded to replace the TIM, thinking just the TIM & not scraping the glue. Using stuff like MX4 they have gotten the same & worse temps after delidding.

In many ways this is an irrelevant discussion though. Whatever makes the temps worse, TIM or gap, the temps do better after a good delidding. After delidding the paste is getting swapped since re-using paste is not the best plan, so 99.9% of the time the glue gap & stock TIM are both goners simultaneously.

And that's the thing man, what good is Intel's TIM in a lab, when it can't hold its name under the IHS. All the chips that I've delidded so far have come up with dry TIM's.

One thing that you may have missed in consideration of the glue and stock TIM is that there's a larger variation of temperature between cores, whereas delidding places that, keeping the lapping part on a side.

It was rather just an observation, the rest is of course his choice, but this comment of yours was fail to even begin with......

Ok, wasn't going to post here anymore but i'll bite on this one occasion as you seem to be even more retarded than i originally thought or lack the ability to decipher information that's previously been posted in this thread.

The reason i delidded was constantly hitting 90-95deg running 27.9 with a core voltage of 1.25v. This chip i'd already proven to scale well so with a lot of headroom on voltage and none on temp, the only way to OC higher was to a) delid and b) run a custom water loop.

I don't run my chip at 81deg 24/7, neither is Menphisto. That 81 deg was max temp whilst running an AVX2 application at 100% load for considerable time which is no where near the stress he will exert on the core during normal use.

So yeah, silly me for posting a 'fail' comment from the start.

Keep dishing out the useful advice.

So far I've done 3-4 games of BF3, 8 hours of Komodo/Houdini, 8hrs of Stockfish. No Bsod yet @ 4.6ghz. More tests to be done of course.

 

The idea of running 100mhz faster for chess makes me feel all warm and tingly inside.
