Ordered a Silicon Lottery Kaby Lake i7-7700K from HIDevolution

I ordered a Silicon Lottery Kaby Lake i7-7700K rated @ 5.1 GHz AND factory delidded from HIDevolution / @Donald@HIDevolution for 2 reasons:

1) I've had the worst luck in the past with Sky Lake CPUs (6700K) always overheating to 98C even at clock speeds (forget any overclocking) and due to my very successful experience with the Silicon Lottery 6700K CPU that I ordered from HIDevolution which gave me a stable 24x7 4.6 GHz overclock.....

I went ahead and ordered a Kaby Lake 7700K from them as well as I don't have time or patience to be installing, pasting or returning CPUs

2) I got it from HIDevolution directly rather from Silicon Lottery in order for them to test the CPU when they get it and ensure it's working to save me the hassle of installing it, testing it, only to realize it's DOA. that way I have HIDevolution's warranty cover me
=========================================================
- Ordered on the 12th of Jan 2017
- Shipping info received a couple of hours later
- 13-Jan-2017: The CPU has reached the FedEx Sorting Facility

=========================================================

I will keep updating this thread with the progress, how I go about on installing it, and how high can I overclock this baby!

Stay tuned

 

Definitely looking forward to see how high you can get the overclock on a good processor in that model. Can't wait to see the updates come through.

 

CPU Arrived.

running @ 5.0 GHz with stock voltage but IC Diamond couldn't keep the temps down so I repasted with Liquid Ultra and to my surprise, it worked better. probably because the P870DM3 is better than the previous P870DM heatsink and is making better contact between the CPU and the heatsink

Benchmarks will come soon

 

Nope, 5.0 GHz not stable with default voltage my system crashed when opening multiple Chrome tabs

So I set a +20mV offset but when opening 20+ tabs in chrome, the temp reached 99C and the CPU thermal throttles so I will try keeping it @ 4.8 GHz for now to see if its any better.

I initially did a wPrime test @ 5.0 GHz with default Cache Ratio:



I will wait for a while till Silicon Lottery release higher rated 7700K CPUs then buy that and sell this one

@Mr. Fox

 

not even 4.8 GHz is stable with a -80mV

overheats to 94C within 1 min of running AIDA64

 

Don't expect a very much lower voltage with newer chips from SL. Remember the silicon is tested on desktops. A higher rated chips doesn't mean it will - can run much colder in your machine could be the opposite with lower clock speed for 24/7. You will never run SL chips the way it was meant for!!
Could you please run Wprime [email protected] and run Hwinfo in the background? Maxed fans. Thanks.

 

no way, that would fry the CPU, I'm telling you opening multiple tabs in Chrome makes the CPU reach 99C @ 5.0 GHz, let alone a torture stress test

even 4.8 GHz wasn't good, 4.7 GHz reaching 92C on max funs with Aida64 stress test

 

oopes, AIDA64 stress test aborted after 3 mins "hardware failure detected, overheating"

 

Dont waste your money on those unless you want to run those in a desktop. They guarantee those speeds at high voltages, which can be maintained by desktop motherboards and can be cooled under water.

Also do not expect to run anything over 4.8-4.9Ghz for 24/7 use unless your ambient temps are super low.

 

not even 4.6 GHz is stable, my previous 6700K ran cooler @ 4.6 GHz

this reached 90C within a minute of running AIDA64 stress test

 

Bro let him try the voltage who you use. So we can see the difference. In temp and wattage. You two can even compare with stock chips. None of the SL chips will ever run 24/7 the way this chips is binned.

Run TS in the background and we can see the difference with same multi, voltage and wattage. Thanks

 

Hmm.. look at a few benches i did last night :

That is weird, there is a good chance your voltage is too high.

Sure thing.

 

running @ 4.6 GHz with default cache ratio, CPU overheat the moment I press the stress button in AIDA64

stock voltage

 

what's a safe undervolt for 4.6 GHz?

I didn't need any undervolt for 4.6 GHz on the 6700K SL

 

@Phoenix for 4.6Ghz try this :

In TS - Core (Adaptive) Offset -100mV , Cache (43 max, 8 min) (Adaptive) Offset -160mV

 

you can't set separate cache voltage on the new Prema BIOS but I'll try -100 mV for core

 

Gotta do it in TS.

 

Please put up a screenie when testing.

 

never using TS, I hate that app

-100mV @ 4.6 GHz with stock cache ratio =



Gonna re-paste again with IC Diamond (CLU on right now)

meanwhile, lemme run it at stock clocks and see how it does

 

please refresh (not lemonade), press F5 to see the screeny

 

A screenie when cpu is in max state, right before temp be too high

Test also with only stress FTP checked

 

stock clocks speeds / stock voltage.........

gotta repaste with IC Diamond. Epic Fail

 

Glad you are taking one for the team I know I would have these same issues, sometimes I think you and I have a lot in common by the bad luck and odd issues we both seem to run into.

 

yeah you know how many times I swapped the 6700K before I got a good one, now even with a Silicon Lottery one, I got the worst of the worst

 

All too high voltage. Use TS for testing. A amazing app for this purpose as well 24/7 use

 

You might want to check if the CLU is making even contact. I delidded my 7700k last night and havent sealed the IHS, just placed it on top. Using it with Kryonaut on teh IHS/Heatsink and CLU on the die.

(Ignore the Intel GPU offset)

Also why do you hate TS, its an amazing application.
This is what i get :

 

yeah gotta repaste again....sighh...I'm tired of this

 

Did you put electrical tape or anything around the die to prevent CLU to leak outward? I was also planning on not sealing my next CPU. I didn't wipe off the adhesive on this 6700K and now it' resealed lol

 

I'm not speaking for you, but for me I just simply lack the patience anymore the older I get (43). I have worked on, built and bought too many computers to count. I have experience, but I lack the desire to spend all my time messing with things so much anymore. I'm a weekend tweaker is all lol.

I think I will be quite happy with my current 6700k that runs cool, and clocks good (bench at 4.8 with stock voltage, after I get Prema BIOS, who knows?). While I love to read and watch others have fun messing around with their clocks, I am willing to spend exactly 0 dollars and 0 time resetting bios, fighting heat issues, heatsink fitment etc...

 

the problem with repasting, is everytime I wanna repaste the CPU, I have to paste the GPUs as well! bloody hell

 

the CPU was factory delidded and sealed by Silicon Lottery but I didn't put electrical tape

I will wipe it all off tonight anyway and repaste with IC Diamond

 

Nope, i even re delidded my 6700k last night, and there was no CLU leakage at all. With the 7700k, did the delid and applied CLU the usual way i do.
But i did remove every tiny bit of the black booger.

 

yeah man, you don't understand how much I hate repasting and burning so many calories and wasting time on it

 

Actually I may be the one person who truly understands

 

To reach the goal you need to play and tweaks. That's the fun. Afterwards is all good

 

You guys have no idea how many times I removed the screws/bottom cover and keyboard in the last week just because of ram issues.

Cool, I'll be delidding my 7700K day 1 once I order the rockitt deliding tool

 

ain't that fun

 

You should try to avoid the huge negative offset thing if you want stability, bro. That often hurts stability and performance. If you deal with temps the voltage tends to almost take care of itself. Trying to manage temps by severe undervolting is not the best approach. Leave that to the Facebook BGA panty-waists and only use it as a last resort, when everything else has failed. Try these settings. This is a retail CPU from Amazon, so no premium was paid for Silicon Lottery. Set all of the power limits in the BIOS to 160000. Set the amps to 1400 (instead of 8191).

You're not going to be benching a laptop at 5.0GHz and higher using nothing but fans. Not with 6700K or 7700K. That's really not even realistic with an air cooled desktop. You're going to need AC cooling for that. Try clock speeds that worked with 6700K and your temps will probably be doable. Here's another shameless plug for the awesomeness of @unclewebb

I haven't touched the VR Current / Amps setting yet, but any idea why it is suggested to not max it out anymore ?

 

Well, based on my brief period of testing, maxing it out let's the CPU draw the watts it wants and that drives up temps. If I max everything out I am seeing between 125W-130W and the temps are difficult to control. But capping it off it doesn't seem to hinder performance until about 4.9GHz. I do not think those power settings worked as effectively with 6700K as they do with 7700K. Maxing them out works, but I need AC cooling to deal with that effectively. There seems to be a dramatic change with 7700K thermals. I did not need AC cooling to manage my CPU temps with 6700K running my max stable/benchable overclock (4.9GHz) because it did not get nearly as hot. I used the AC cooling primarily for benching the GPUs with severe overclocking.

NOTE: I do need to investigate the fit of the CPU heat sink a little closer to be sure I am not blaming the 7700K for sloppy CPU heat sink fit. If the IHS is even 0.1 to 0.2mm shorter than 6700K that could be enough to cause a fit problem when low contact pressure was already a problem. I may need to shim it even though I did not need to before.

Edit: I am also booting the system at 5.0GHz on all cores/threads using BIOS settings. I'm not taking the old approach of booting at a lower clock speed and ramping up with ThrottleStop or XTU. If I do not manually launch ThrottleStop to tone it down, I am idling on the desktop at 5.0GHz and running everything in Windows stable at that clock speed. That's a huge leap for air cooled laptops. I never believed we would see this before, but now I have to figure out how to manage it thermally. I'm tickled this is even possible, and I suspect that Brother @Johnksss@iBUYPOWER is as well. Might have to go back to the days when all benching had to be done using AC to manage it effectively, the rest of the time using a boring sissy gamer-boy clock speed, and if that is what it takes it's still worth it. 6700K having such low temperatures with high clock speeds was a very nice anomaly.

 

Have you measured the thickness of IHS and the whole package from 7700K vs 6700? Maybe teste the one from 6700K(if you still have the chips). The PCB on 7700K is a very small bit thicker as I have seen. Could you post all numbers if you have time? Hope you understand what I meant. Also use pressure tape between die and IHS. Thanks.

 

I have not done that yet. Maybe sometime this week, because I am going to try to improve my temperatures so I can hopefully at least run 4.8GHz as my daily driver with good temps.

From another thread...

New walk-through for @Prema BIOS that was just released to partner shops, including @Donald@HIDevolution and @Ted@HIDevolution and @Eurocom Support for distribution to their customers. And, a HUGE shout out to the newest Prema Partner... our friend @Larry@LPC-Digital !!!! Welcome, sir! Here is the full list of PremaMod Partner Shops.

Please see the special messages at the end of the clip. Great work by Prema and the team of testers that helped validate the success.



@Phoenix - try this and use the ThrottleStop settings already provided. Below are the temps running the 4.6GHz ThrottleStop profile with the BIOS settings shown in the video while rendering this video.

 

I definitely think that there is a heatsink issue or something similar if your temps are reaching 99C instantly.

 

@Phoenix

4.8ghz Handbrake Encoding test :

 

What clock speed are you dealing for in 24/7?
How are the voltage fluctuation on 7700K? Are there big fluctuations under maximum load?

 

I settled at 4.8-4.9Ghz. Without the cooler under it.
The voltage variation usually is about .015-.075V under most loads.

 

@Mr. Fox @Prema @Papusan @bloodhawk @Johnksss@iBUYPOWER

After my horrible experience with Liquid Ultra, I repasted with IC Diamond. I tried your settings Mr. Fox by lowering the IA/Current to 2400 and lowering the power limits to 160000


Here are the results:

@4.7 GHz (stock voltage) =



@ 4.6 GHz (stock voltage =




I've wasted 50 mins repasting the CPU/GPUs as I have to repaste the GPUs everytime I wanna repaste the CPU, running very low on IC Diamond now

I'm gonna go back to my old trusty Silicon Lottery 6700K that was able to maintain 4.6 GHz @ 82C max and sell this one.......

Also, @Mr. Fox , should there be any screws here as I've pointed out? I can't find them although I could've sworn there were screws there.......

 

Yes, you are missing 5 screws.

 

Snap! I think my cats ate them! Gotta go on a search mission
