Intel Kaby Lake i5-7600K CPU Re-Lid Overclocking Results @ [H]

Looks to be a decent cooler, can't wait to see it up against the rest of the field.

I've been considering the Scythe FUMA but it is hard to find in stock at a reputable retailer.
 
I am impressed that the mini-ITX motherboard was able to support 5.1ghz. Is that a 5 +2 power phase design? I wonder if it can OC as well with the I7's?

Looking at specs this motherboard support greater then 4000mhz DDR4! Mini ITX no longer means lower performance now days.

As for the RTV I kinda like it, gives back yard build feel to it :D. I just wonder if it adds any Z-height compared to something like super glue or it makes zero difference? I see people recommending super glue ( I guess acetone could be used to remove the heat spreader or to soften up the superglue if you have to).
 
Thank God there are guys like the dawgz at [H]ard|OCP who continue to do shit like this, and share their experiences with us (especially those of us without the cash or means to perform such experiments and testing ourselves). Again many thanks and mad props to you guys for continuing to hook us up with information on the Kaby Lake de-lidding/re-lid journey. The videos, the performance and temp info, the details of the de-lid/re-lid process, and more, this is all extremely invaluable. You guys just don't quit, like the fucking Energizer bunny on steroids. Gawd damn Kyle. I don't even know what to say. Not really sure how to relay to you guys how much we appreciate all the ridiculous work you guys do on this site. I'll keep reading until the day I kick the bucket and move on to CPU overclocking adventures in the afterlife.

Personally I didn't like the fact it does not have a flat surface. There are many others with direct heat pipe contact and a flatter surface.

But seeing the temps there is nothing to worry about.
 
In my opinion Thermalright True Spirit 140 Direct is of a very bad design in the CPU-contact department. Termalright must have saved a few bucks by removing the bottom contact plate, but the reduced contact surface isn't going to be compensated by the enormous pressure. A Deepcool Gammaxx 400 would fare better here (and quieter and cheaper). As "someone" had said: There is no replacement for displacement!

You're late! It's been a while smaller boards offer equal and sometimes better performance than huge ATX. There is a reason for that, shorter lines... My last and current builds are µATX and my next will be ITX. Unless you want to do SLI, why would you go full ATX?

There is one review yet of this board, with [H] review just around the corner.

Exactly, if I had more time I would post both pictures side by side for comparison, it's night and day.

Yeh, for performance per size/weight this cooler and NH-U14S are best size HS for money. They perform very well w/o being to heavy like twin tower HS.

Kyle on Prime95, why don't you just use an older version if you don't like AVX , I think 26.6 is non AVX and 27.x+ are AVX.
nice review (PS: I like the added vids in last few review).
 
Im gearing up to build a new system, and finally replace my 2600k. the main take away for me, is to go 7600k, not 7700k, especially since gaming is my thing, and my goal is a stable 5G
 
Nice information.

Would that silicone be amenable to application out of a small medical syringe or is it too thick?
A medical syringe with a longer end-hub might lay down a more narrow bead. IDK, just a suggestion.

That is actually what I used. Need to find a large gauge needle now that will work as a nozzle.

I wanted to see if it could handle it and how hot it would get on this particular configuration.

As for just overall, I like the realworld workload approach that RealBench uses.
 
I like how Thermalright includes a 'shim' for the 1151's. I literally just installed mine last night, albeit, on a 7700k. :sick:
 
Right, I agree totally on that Realbench is much more real life app than prime95 but just throwing that version info out there.
Yeah, we have been using Prime95 for about 20 years now. Just to a point where I do not think it is as important as it once was. The fact is we moved away from it a couple years ago as I found that using HandBrake for full encodes was better stability starting place when testing.
 
when i briefly glanced at the cover pic for this story i thought it said fuck you on the chip
 
I would think the smallest ( read at least) of the larger bore needles would be an 18 gauge and that you dremel off the sharp tip.

Better yet would be 18 or 16 gauge angio-caths. Due to their soft plastic outer sheath and disposable nature.

That said, those supplies are rather hard to come by unless you have a contact in the medical business.
I have 99 of these left. Let me know if there is something you would suggest that I could use with these. Not much into needles knowledge-wise.

Looking good and an impressive overclock on air.
But still, this is on an open bench, I wonder how it would do in an ordinary case, nothing fancy but something like a standard $80-$100 case with just the usual 2 or 3 fans that comes included.

About the Thermalright cooler, can we expect a review soon? Please?
 
Thanks for the awesome review. As someone who still air cools I was really happy to see a 5ghz 4 core CPU. Awesome!

I've been an I7 fan since my 2600k but have been keeping an eye on the I5's for the last couple of years and this is pretty cool.

The mITX ususally have less power stages then the bigger boards, they get to work harder when pushed plus less of them for a more even power. In this case it doesn't seem to have made a difference which is great.

No. Take a look at some of the eurogamer/Digital Foundry videos on Youtube -- you'll see that the i7 is much better at stabilizing minimum FPS than the i5's are. ~ 5 years ago the i5 = i7 for gaming was true.. that's not the case today. (Remember i7 also has 33% more cache, not just the hyperthreading).


(talks about and shows minimum fps of i5-6600K vs i7-6700K)

I'd really like to see [H] do a full/deep comparison of i5 vs i7 for minimum fps and VR frame latency ...

Anyway at this point just wait a few weeks to see what RyZen has to offer.

Thanks for bringing up the cache. . .I forgot about that while drooling over the 5ghz and air cooling. They do make a significant difference in a variety of things. I'm pretty sure the improvements I've seen going from my 2600k to 4930k had a bit more to do with caches than the cores/threads. I saw it before with many of the other CPU's I've had going from P2 to P4 and so on.

This whole relidding thing temp gains on intel procs is seriously turning me off of their procs. This is the kind of thing they should be doing at the fucking factory. I shouldn't have to risk destroying my pricey CPU just because they decided to use sub-par thermal at the factory. Premium price, sub-par thermal. Fuck that.
 
If 14ga ends up to be too much flow, just pinch the tip with some pliers to restrict the flow.
Yeah or alternative could order the 1st one in the link I provided as they go down to 18ga.
Think they are luer lock-slip compatible as well, might have the answer in their QA, but not many for the price and your find is a much better deal on that.
Cheers

Standard luer connector. What you want is some blunt tip needles, very common in the DIY vape community.

These would be fine for your purposes: https://www.amazon.com/gp/aw/d/B01K...36_SY340_QL65&keywords=blunt+tip+luer+needles

Luer lock and slip are compatible, btw. Not that it matters if you buy the ones I linked, since they are slip like your syringes.

I just came back to look at your needle suggestion.
That gauge should be just the ticket.
Kyle's syringes don't have a luer lock though, which is too bad. It should work OK as long as you don't have to push the silicone too hard.
If you have a really viscous solution though, the needle will come off the end.

If that happens, maybe a little super glue on the side of the syringe were it meets the needle?

Or, look for some 1cc luer-lock syringes, which would be the best thing. Actually the syringe that NT H1 comes in is a luer lock if you could reuse one that would be the deal.

I wasn't aware of the avx issues with Prime95. I just ran a 19 hour small FFT on my Skylake chip but I was still at stock voltages (only a mild OC to 4.4). I also read about EPS connectors burning out.

Safe to assume the burning up issues are only if applying over stock voltages?

Worth keeping in mind that we were running CPUs using Prime95 for stress testing for literally months and months and months while overclocked and overvolted. I do not think there is any immediate danger with using it for at home stress testing.

I'm glad you were able to discover and recognise how shitty of a company Intel is. I made this discovery myself back in the year 2000.

Is it the thermal paste is sub-par or the application of the paste is sub-par? You can take the best liquid metal TIM and really screw up a cooling job if you do it wrong.

I don't think there is anything "wong" with the OE TIM, but it is not as good as say Noctua. That said, I think the CLU is MUCH better than both of those. I also think we are getting much better results by reducing the Z height as well.
