Delidding Intels 7700k drops temps by almost 30C

[DELTAprime]

Ok, time to google how to delid a CPU. lol.

Temps going down is good.

 

So in this case, DO delid your CPU.

(unless intel gets their shit together and uses good TIM)

Literally every CPU I've ever used has been soldered lol

Thankfully Intel has some more time to deal with their thermal issues.

 

When originally tested, the 7700k CPU could obtain 5Ghz speed with 1.35v but was hitting temps of 100C!

"By delidding the CPU and applying CoolLabatory Liquid Thermal Paste and a Kraken x62 cooler, they were able to push it to 5.0Ghz using 1.344v with the fan set to 50%. The pump was at 65% and yet the temps plummeted by 30C.  An average of 26C."

 

Intel is set to launch Kaby Lake with the I7-7700k at CES in January 2017 so they have a little time to work on the thermals.

I looked to see if i missed this post already out there, I probably missed it 10 pages back so sorry if it is a repeat!

 

NOTE ** This is not a recommendation to delid ANY CPU!  It is advanced knowledge and if you have any questions I suggest you google the video Linus did on the procedure.  The point of this post was to show that the thermal compound Intel is using on these pre-production and review CPUs MAY result in much higher temperatures.

Amazing how early they ripped the IHS off the beautiful thing. No respect, tsk tsk

That's huge.  I had heard it was running hotter than Skylake but if this is why, then there's hope - maybe it's not a bad chip after all, just a terrible thermal solution.  Hopefully when they ship them they will have fixed this by essentially factory-deliding them  

pretty amazing to think Intel found a even crappier TIM then they put in the 4770k

Yeah my Athlon 64 was from the green team, even had an Nvidia Nforce motherboard.

I thought we gave up on the GHz race over 10 years ago.........

 

Why do we need a 5GHz CPU? We need a 3-4GHz CPU with significantly better IPC. Not some kind of BS overclocking for better performance.

[Remixt]

I've wanted to hit 5GHZ on a cpu for a long time. I might drop some bones on this if there's a decent bin of cpus. Not that it matters, I'm just a huge fan of the number 5.

Because it has so minimal performance gain compared to the previous gens?

That's not my problem. That's Intel's problem.

As a matter of fact its not a problem for them, they do not have any real competition. So instead of making serious developments they just sitting on their money...

Your the consumer not Intel, this is very much your problem.

so intel should be entering from low earth orbit?

I don't understand why Intel are doing this to themselves. Especially with Zen launching so soon.

They sat on ass that much they didn't realise the tortoise caught them up.

 

Ironically its almost the exact same thing that happened to them (but in reverse) back in the Pentium/Athlon era. AMD were so far ahead with Athlon they got complacent and stopped innovating, Intel dropped the Core 2 series and AMD just couldn't answer it. That is why Intel has been so dominant for so long, I wonder if this situation will result in tables being turned yet again.

 

That said I genuinely wouldn't be surprised to hear that Intel have appeared to be sitting on ass because they've secretly been creating a replacement for the Core I series. I don't think the Core I 10070 has a nice ring to it.

If it were easy to significantly improve IPC, don't you think they would have done it? The instructions that have been around for longest are pretty well optimised already. Gains we see in recent generations have been a combination of general optimisations with small improvements, and adding new instructions to do specific things a lot faster, once supported.

 

I'd settle for the other option: more cores! I'm not saying that making software that can take advantage of using a large number of cores is easy either.

This is the real source. Scroll down and see his previous testing.

 

He used a big water cooler(corsair h110i) and got avg 83 degrees with 4.7 Ghz @ 1.264v.

 

After delid and using another big water cooler (Kraken x62) he got avg 72 degrees with 5.1Ghz - 1.376v.

Jesus, don't these people understand how variables work?

 

For a consistent result they must keep all variables the same across all tests. This moron changed just about every single thing he could, different cooler? Check. Different clock speed? Check. Different voltage? Check.

 

He might as well say green is better than purple because my bacon tastes of sunshine.

He isn't doing a review or scientific testing, he's just a guy on a forum was trying to get to 5GHz stable anyway he could.

 

From the tests he has done you can see that a delid makes a big difference. We just don't know the exact because yeah, variables.

That's fair enough on a personal level but its still totally meaningless data.

 

And no I can't, that's my point. If he is going to keep changing things for each test I have no way of knowing if its silicon lottery, the delid or his cooling causing the changes.

I had another look at the thread and I think he did actually do a proper comparison. I can't see where it says he used different coolers like people said. All the voltage settings are the same at 1.344v in the before and after screenshots.

Before and after delid with Liquid Ultra - 5Ghz, 1.344v, Kraken X62 @ 50% fan and 65% pump (i.e. silent), Prime95 v27.9 - 26 degrees difference (~30 degrees max temp difference)!

 

I mentioned the other time he used water cooling to show the very rough comparison but this one looks meaningful.

After reading the entire thread he makes a huge point right at the start, he's running an engineering sample on a beta BIOS using software which has no official support for his CPU yet, he has no way of knowing how accurate his temperature readings actually are. He even goes on to say he has witnessed a ~15°c discrepancy between BIOS & Windows.

 

The more I read the more I'm thinking he was not a moron, tweak town were morons for using his data. The thread is in reverse (so earlier posts are at the bottom) but reading the start he makes it quite clear his numbers are likely meaningless.

 

Edit

 

Start cooler: Thermalright 6 heat pipe tower, Corsair SP120

Second cooler: Corsair H110i set to quiet mode (I'd never leave it in performance mode due to the increased noise - I don't want to sit next to a vacuum cleaner!)

Final cooler: Kraken X62
