Nice, that should alleviate some of the idle temps.

 

It does make a huge difference, especially if you want the fans to stay low.

 

Rarely when the laptop boots it will ignore the BIOS set OC and will boot with turbo boost disabled. Have to restart or shut off/turn on to have correct cpu clocks.

It seems to affect 9900K aswell.

Not to mention that sometimes (1/20 ) during boot it does not even detect the ADATA Sata3 SSD with the windows 10 until I completely power it off and on again ... this is a BIOS issue which is not fixed yet even in the latest bios.

 

Had a 8700K and delidded 2 times. After 2nd delid I got good temps. With 28C ambient temp I got 80C max in Fire Strike for CPU temp with 4.6 Ghz all core. However I wanted even better so I wanted to delid again to change the factory installed IHS to a copper one.
However during my 3rd delid process the CPU died.

Regarding temp/performance what would you guys recommend? Another 8700K or a 9700k?
I tried a delidded 9900K in this chassis and this cpu is a no go for this laptop. 1 power brick is not enough and can not hold 4.7 Ghz during a Cinebench run and core ratio will jump all around between 3.6-4.7 Ghz. Tried 4.6 Ghz with undervolt and that is stable, however it was just too hot for me.

What CPU would you guys buy?
There are 3 things that are important for me:
- more FPS
- less or no microstuttering at all
- lower temperature with same settings

There are 3 CPUs on the list which I considered:
- delidded 8086K USED for $335
- brand new 9700K for $410
- brand new 8700K for $420

I watched comparison videos on Youtube and with same settings 8700K beat the 9700K in Fire Strike and in 1-2 games, however in almost every tested game the 9700K performed same or better than the 8700K. Regarding temps they were same or lower however these tests were performed in desktops with AIO cooling so they dont really represent the temperatures in a laptop.

With stock settings how does the 9700K perform in a P775TM1-G chassis paired with RTX 2080? Can it stay under 80C in Cinebench R15 or due to the outdated manufacturing process it is running as hot as a 9900K and the P775 is struggling to cool it down so I should just got with a used 8086K ?

 

Did it just refuse to boot with the custom ihs? If so did you try again with the stock ihs?
Sometimes the copper ihs is too thick and adds too much pressure, resulting in some of the pins not making contact.

I had both 8086k and 9900k in my p775tm1 with a single 330w brick and a gtx1080. You do need a decent undervolt to hold 5.1Ghz for 8086k and 4.8Ghz on the 9900k from my experience. Did you have the PL1/PL2 and VR Current Limit raised?

As for CPU recommendation, if you can find a used binned 8700k/8086k, that'd be my go to for the p775tm1.
It's just hard to make a good argument for the current R0 9900k.

 

Loving my 8086K. The average 8700K requires quite a bit of voltage to hit 4.8Ghz. Some people have GEMS though and they are certainly great chips if you have a good one.

But, I can put out less power at 4.7Ghz With my 8086K than a 8700K will at default speeds usually.

My 8086K runs 4.7Ghz like it’s nothing. It never throttles or downclocks from that either.

I can also run 4.8Ghz or even 5Ghz fairly easily. But I’ve gone back to standard thermal paste and Battlefield V really pushes a CPU harder than any stress test I have.

I think 4.7Ghz with a -0.180 undervolt is the sweet spot for me.

 

The stock IHS is copper by the way.

 

*nickel plated copper

 

I broke a 6600K after multiple delids. The first delid was good, and I resealed the lid back on with white cauk used for sealing around toilet bowls. It ran excellent for a while at 5.13Ghz which was incredible for a 6600K i5. I originally purchased it from Silicon Lottery as a (4.8) bin version.

But I delidded again and again and eventually killed the thing.

 

Yes, that's why it has a silver appearance, but it does not impact the cooling really.

 

Thanks all for the info.
I ended up ordering a CPU which I completely forgot about ... the 9900 (non K)!
8700k/9700k both are 95W CPU, however 9900 non K is a 65W CPU with all core ratio of 4.6 Ghz. So in theory it should be cooler or same but in performance it easily beats both.

 

Intel should just make high end K series processors with a .999 silver IHS. Silver is not that crazy expensive. And we’d be able to really get our monies worth. These processors are like $$$$ super expensive. What’s another $25 in silver cost per cpu. They could just add that to the msrp. Or add $100 to the MSRP. They’d be the only company selling a stamped piece of silver for 4 times what it is worth lol

 

That 65W TDP rating is at its base frequency of 3.1GHz.

 

You underestimate how cheap Intel is. That is why they stopped including stock CPU coolers with unlocked processors since Skylake, and stopped using solder until Coffee Lake refresh.

 

9900 will be fine. Still a beast. You know you can sell your 8700K as defective on eBay for quite a bit. Just a heads up. I’m honestly shocked sometimes seeing the prices that bad components fetch on eBay.

I saw a dead 2080Ti sell for $450.

broken modern i7’s usually pull $100+ or sometimes more.

 

Testing and reliability, how does the silver IHS adhere to the solder? Would it need a gold layer or something else? Does it cause cracking? That's the sort if question that needs a lot if testing and validation before Intel could put out a product for a niche that likely wont see a cost to performance benefit compared to that cost going into something else.

 

Well that sucks, then the 9900 is just a 9900K with locked multiplier and temps/voltage is not better.

has anyone tried a 9900KS ?

According to this test results:


It costs more however it is a much more efficient chip and runs about 15C cooler than the 9900K with the same settings.

Maybe this is the 8 core intel chip we have been waiting for to use in a Clevo laptop? 80C instead of 95C to me worth the extra money ...

 

You're gonna need some Prema magic for the KS not to throttle into the abyss in the Clevo.

 

Not if I underclock it
( ͡° ͜ʖ ͡°)

An underclocked 9900KS to 4.6 Ghz still easily beats a 9700K or 8700K .
Not very cost effective I dont doubt that but performance wise seems like the best option...

 

When I buy a (8) core cpu to replace my 8086K. It will be a 9900KS.

Silicon lottery sells them for cheap and just have them delid it for you.

 

Well according to their own binning statistics, almost 1/3 of all 9900KS can hit 5.1Ghz <1.3v

 

Yes but they run a -2AVX offset so they are really hitting 4.9Ghz.

 

They want like $1,299 for the model that runs 5.2Ghz with a -2AVX offset.

 

AVX is a lot more stressful, a lot of people wont stability test with it.

 

Caseking has 5.1Ghz 9900KS, they don't specify exact voltage from what I can tell. They only mention that the max voltage used is 1.39v +/- 30mV depending on other components. But that's for both 5.0/5.1 versions.

While 8Pack's 5.1Ghz 9900K states, "Guaranteed minimum overclock of 5.1 Ghz with an AIO 240mm cooler with 1.35-1.425v"

9900KS is tempting because of a lower voltage. But performance clock for clock to a P0 is meh, and even more pointless when you have a good P0 sample.

 

Yes but if you stability test at 5Ghz using non AVX and your good to go at like 90-92C. You go run BFV your system is going to throttle hard.

It feels like -AVX is not a real overclock to me.

 

That was for the P8.

Well, the 9900KS throttles down to about 2.1Ghz in a matter of seconds with stock firmware on the P8.
The P7 is still officially supported by Clevo so the latest BIOS should at least "support" it...

 

Intel were not exactly thinking about... Well much when releasing it to be fair.

 

You mean buy from their tray and then let them delidde it for you? Then you'll get their worst bin.

I hear you. der8auer recommend at least 3 bin AVX offset. But don't listen on such advices

 

I meant select the pre-tested bin you want and add the delid option. You could buy the 5.1 model and get the $49.99 delid option.

Sometimes I’m not so certain about Siliconlottery though. When I purchased a CPU from them in the past it was sealed in the box. And it didn’t run 4.8 like advertised. It only ran 4.7. I had to delid it myself, and resort to custom water cooling and extreme voltage to attain a much higher overclock.

^ So how are they testing processors if they’re are still sealed in the package? Is he guessing with batch numbers? Or possibly using a heat gun to carefully open and re-package each processor?

^ I really don’t know. I just know I paid over $300 for a binned i5 that was sealed in the retail packaging. And it did not run at the speed that was guaranteed.

 

Doesn't fits with what you said # Silicon lottery sells them for cheap and just have them delid it for you#

Not sure what happened to you... But all is pretested if they get a OC bin numbers... And I'm sure they know what batch is worth to be put for binning.

 

do you run your 8700K with an AVX offset? -3?

 

I use ThrottleStop (4 profiles for different usage). Several ways to lower power consumption/heat. And my usage ain't this type load. But if you run games/software with avx instructions on daily basis I would use the feature.

 

How are you guys destroying processors?
All you have to do when you delid multiple times is make sure you don't static shock the SMD's, don't rip them off, and don't get any Conductive Balls of Doom anywhere on the backside, anywhere.

 

My first couple of delids I used a razor blade which does have some risk but the kits a very safe.

 

I saw some real hardware gore, when reading up on delidding initially. Decided to get a cheap Delid Die Mate 2, it served me through 8th and 9th gen

 

Got the new cpu

 

Nice, let us know how it works out.

 

Man that gray looks so good. I feel like my baby is ugly in comparison.

 

Yes if you would not careful you could slice into the pcb and instant dead chip.

 

I just didn't want to cheap out on a relative low cost tool that would significantly reduce the risk of ruining the cpu.

 

It's a lot quicker too

 

Just please don't plaster stickers all over it!

 

A nice big white apple sticker

 

I’ve got a few on there already.


Jk

 

I don't have a single sticker on, not even the intel/nvidia ones. It kinda reminds me of a sleeper build this way.

 

But each to their own

 

mine has zero stickers too. Previous owner removed all the badges as well.

Anytime I talk about how powerful my 15” laptop is, people kinda look at me like I’m crazy for a minute.

“That big ole ugly thing?”

 

Hello world!
I have somewhat weird question here.
Is there a... non intrusive way to make powerbrick's output cable longer?
