"For everyone who has orders out, whos has actually shipped? I hedged my bets through newegg and Amazon USA and neither has shipped. Spoke to CS w Newegg got a very helpful rep, said that in total they shipped 87 9900Ks. I asked my spot in queue and it was 557 lol. She said they are expecting more stock to be received 11/21, 11/28 and 12/6. Got pretty much the same word from Amazon but less detailed. So figured people would appreciate hearing the limited info I have on this."

A 9900k in a Clevo has already happened.

Good luck with building your P870-killing wunderboard.

 

Sure. Plenty 5.4GHz is the standard and near sub-zero Idle temp in desktops as well You mean Silicon Lottery and Case King do a Crappy binning job? Weird they can't find all the golden samples as you stated. Maybe they use the wrong people/workers for the job?

 

So, posted in the comparison thread videos related to the solder and delid of AMD and Intel CPUs.

http://forum.notebookreview.com/thr...99-xeon-vs-epyc.805695/page-257#post-10811509

 

haha dont forget that SL and caseking dont just do single CB15 runs for stability testing no one said their 5.1/5.2/5.3 Ghz samples cant run CB15 at 5.4! besides, SL for one bins voltage steps so they dont check every CPU´s lowest possible voltage at a given multi. given that, there is always potential left untapped in each SL cpu purchased also, SL tests with 240mm AIO for a more "realistic" and "average user" scenario. so yeah, sure u can achieve way more with dual 420 rads and a water chiller @Mr. Fox

 

All you have proven is that it cannot run at 5ghz+.

Gj on that.
Also videos showcasing how PC's are running at 5.4ghz stable is not the same as you showing me a picture of a 5ghz 9900K in a desktop, prema's 5555mhz 8700K that would crash the instant he would start anything that isn't his desktop or dokuments or your picture of a massively thermal throttling 8700K in a P870DM that would crash after a couple of minutes at best.

Stop deluding yourself into thinking notebooks are on the same level as desktops, because they're not. If you want to prove me wrong, show me any kind of video proof where the turbook runs 5.4ghz stable, oh you can't?

Well that settles it then.

 

Right. Maximus and Rampage are great boards. There is no substitute for top notch products. That's why I buy them. Already tried the less expensive bargain board and gamer-boy crap approach and they're junk.

However, there are not a lot of chips that will run 5.4GHz with low enough voltage to stay cool enough on ambient temps with water to avoid thermal throttling and remain stable. There are certainly some, including samples I have benched myself, but not "plenty" of them. Plenty suggests the majority will, and that does not seem to be the case.

When you use abnormally cold air or water, it helps a great deal with all CPUs, including poorly binned samples that are not stable with the same overclock at the ambient temperature with an ordinary water loop.

 

In your world... Would this one run perfectly fine in most tasks without thermal throttling or SHUT DOWN because it's used on an desktop MB?

From Case King


For @Danishblunt ...
Note 2: For overclocked processors of the Intel "Coffee Lake" series, for the use of (rare) applications with AVX support in the UEFI, an offset value of at least 3 should be set in relation to the OC clock to avoid overheating. In order to explore the maximum clock values of the binned CPUs and to ensure their stability, der8auer tests each individual sample for at least one hour under Prime95 26.6 with 1344K.

 

The rub that people often forget is that, under normal circumstances, water gets too hot. And, it doesn't take long for it to get too hot to be useful. Water also stores heat longer than air. That is one of the reason benching laptops on AC has always worked well on overclocked laptops. Thermal changes using freezing cold air are very fast compared to water. Scalding hot water is no more effective at cooling than hot air. You need to use freezing cold air or super cold water, at minimum, or the benching session is going to be time limited. Once it gets too warm, the fun is over. This applies equally to desktops and laptops.

 

what we need from clevo is a redesign on their laptop, which we know most likely won't happen. tho this maybe the last laptop with 870 chassis housing 9900k. still hoping they'd get a better board + heatsink.

 

They will have to change something for power and cooling or it will not be fully usable even runnung stock. They should over-build the power delivery system as they did the P570WM.

I am skeptical the cooling will be any good. I don't see any way it can be good because the chassis is too small to hold enough no matter how hard they might try. Even a gigantic tower cooler with 6+ heat pipes and dual 120MM fans for a contraption nearly as big as a laptop is not good enough for meaningful overclocking on a desktop. I don't see how a heat sink the size of my hand is going to ever be adequate without help from an air conditioner.

 

Seems like a replay of the 8700K launch. I bet the majority of initial stock all ends up going to big system builders like iBuyPower, CyberPowerPC, OriginPC and bigger OEMs like Alienware.

This is becoming a trend in general. We see some similar things happening with video cards. Stock has been an issue with NVIDIA and AMD products as well. Maybe it generates more hype. I am still waiting to see an EVGA 2080 Ti FTW or Kingpin Edition. Not going to settle for something less or inferior just to get it faster or cheaper.

 

it needs to be at least the size of p570wm and 2 powerful fan on it, not just some 2nd smaller fan that doesn't spin until temp is like 85C.

 

Which AMD release are we talking about? GPU was either miners or bad value (Vega at release, also on amount available due to HBM2 supplies, etc.). As for CPUs, EPYC was a paper launch at computex last year. The HEDT has been fairly solid, unless referring to announcement and doing the cut down 12 and 24 chips later. I didn't watch availability, but I thought last year with X370 there was a board shortage rather than CPU shortage. I didn't watch the second gen Ryzen supplies this supporting, but didn't hear anything major except on waiting for release on certain chips I think until May, but that is waiting for the actual release, not low volume after release.

So, seems that applied to the rough starts last year for AMD more than this year, whereas this fall, it was Intel with a second year of paper releases, although now known to be manufacturing capacity restraints related to 14nm due to 10nm delays, while Nvidia's is likely over production of 10 series chips due to mining craze (where evidence suggests AMD scaled back on the inventory buildup during Q1 and Q2), meaning do absurd pricing and side grades on the new stock to discourage purchases while clearing inventory, which keeps demand lower which in turn minimizes amount of supply and costs for inventory on the new cards while clearing the old as a balance sheet matter.

no need even for that. i mean, look at the SLI machines we already DO have, such as the P870: in total, it can dissipate 2x180W GPU + 95W in CPU all at stock, so a sum of 455W of TDP. why not just divide that up into 250-275W GPU and 180-205W CPU? that way one could easily fit a powerful desktop GPU such as a downclocked 2080 Ti or full fat 2080 in combination with an unleashed 9900K or even an HEDT part. just gotta make it happen the right way

 

Older P570 would struggle hard with 2x190w graphics. Wouldn't work. @jaybee83

Make it 5mm thicker and the same for deepness (Clevo added thickness when they changed from first gen P870DM - Shouldn't be a problem this time either). Add in 4 thicker more modern and stronger fans. More noise can be fixed. Put in a second more quiet fan profile in firmware (+ better fan control software) for those who want more quiet machines running stock configuration.

 

Now thats absolute wishful thinking if I ever read one.

There won't be any full RTX 2080 or 2080ti for the same reason there is no full GTX 1080 TI. Also the CPU is an absolute nightmare to cool, even a quality liquid cooling system with a H100 has problems cooling that crap at stock.

 

oh cmon guys, seriously? are we really splitting hairs here now?

the aforementioned post referred to the general size and available volume of a P570WM type machine with an overall beefier cooling system. im NOT talking about "exactly the same" cooling system as in the P570WM to be adapted for current hardware. that would be retarded!

also, im not "wishing" for a specific 2080 Ti mobile or even insinuating that something like that will be released. thats for a crystal ball to decide and im usually not in the habit of using one

what im saying is this: we already HAVE laptops capable of dissipating a total of 455/475W worth of TDP in gpu and cpu components. we dont need fancy pantsy water cooling. we dont need supersized bricks like the P570WM and 20kg of copper to make it happen. we already HAVE solutions! just that they have been implemented and divided up into different parts. so why not use existing solutions to tackle new problems?

who still needs a SLI setup for gaming? SLI is just for benchmarks at this point in time. so: cut out one of the GPUs and assign half of its TDP headroom (and thus cooling) to the single GPU left and towards more legroom for the CPU, respectively. that way you CAN have something like a 2080 and a 9900K in a laptop the exact same size as a P870.

thats 230W for the GPU and 150W for the CPU, total of 380W --> 75/95W LESS than a P870 equipped with 1080 SLI and an 8700K.

if everyone starts nitpicking and tears everything apart before we even have a general idea of how something might work, then nothing would ever be done

PS: be it 180 or 190W per GPU, doesnt change the essence of my point here @Papusan

 

I fix it for you And no need to cripple aka remove SLI options.

"Make it (5mm) thicker and the same for deepness (Clevo added thickness when they changed from first gen P870DM - Shouldn't be a problem this time either). Add in 4 thicker more modern and stronger fans. More noise can be fixed. Put in a second more quiet fan profile in firmware (+ better fan control software) for those who want more quiet machines running stock configuration."

 

already adjusted my post accordingly. but those 20W difference dont change my point in any way. how is removing SLI "crippling" in any meaningful way? would u rather stick with 1080 SLI or get a potential option to have a single 2080 or even 2080 Ti in a laptop? id go for the latter...

See.... Changes like this smells too much Azor. Remove SLI and going with single graphics doesn't mean you will get a lot more powerful options. All we risk with this steps is smaller and thinner models. It's pure facts. One single notebook model out there with proprietary (special designed, more powerful graphics) won't work.

 

It would be awesome if Clevo made a 6-full pipe CPU cooling system paired with dual fans. I took my MSI WT75 apart a couple of weeks ago and am impressed with its 5-half pipe solution paired with a single fan, but I cannot help but think its probably going to limit a 9900k.

 

thats completely the wrong way to look at it. going with that reasoning, the P870 is already the wrong way because it doesnt support HEDT cpus like the P570WM did. in fact, ALL machines following the P570 would be "thin n flimsy turdbooks". how does this reasoning help us? it doesnt.

lets take this step by step, because apparently you guys love to get lost in details and keep missing the big picture:

- with the 20 series, the gpu trend is heading towards higher TDP wattages vs previous 10 and 9 series
- with the 9 series, the cpu trend is heading towards higher TDP wattages vs previous 8 and 7 series

question: can we just slap a 20 series gpu into existing SLI machines and call it a day? no. and why? because they require more power and better cooling.

question: can we just slap a 9900k into existing designs and call it a day? no. and why? because it requires more power and better cooling.

so whats the next step? whats the easy and natural route? to completely redefine existing designs, start from scratch and somehow squeeze in two 2080 TIs in SLI combined with a 9980XE into a laptop the size of 2-3 P570WMs?

or maybe look at already existing designs, capable of 475W TDP dissipation (20W making ALL the difference here according to @Papusan apparently ) and see what we can achieve with that first?

and then we csn take it from there!

its just silly and nonsensical to either talk alienware turdbook designs with soldered components or expecting to have ultra extreme and unrealistic laptop designs that no one could afford or even be interested in to establish a large enough user base.

so: why not apply common sense instead? dont get lost in insane ideas.

again: we HAVE existing solutions capable of 475W TDP dissipation. so lets use thst first before we completely give up (alienware turdbooks) or completely go nuts and thus nowhere (HEDT SLI in laptop).

how is this so hard to understand? seriously...

well thats the thing some of us been hoping for. 200-250w of cooling for CPU and in the end it is still a gaming laptop so clevo prioritize cooling to GPUs instead. unless they come up with two heatsink set, 1st is original setup for dual GPUs, 2nd is for less cooling dual GPU or single GPU and allocate more cooling for CPU.

more cost, i just dont see that happening.

they could just go for 18 inch or 20 inch with same thickness then we'll all be joy

we have had many wishful thinking, never really materialized. p870 was only worth getting because of AMD's core count war, or we would have a 6 cores for next 10 years.

 

You are completely missing the point, while I agree with you that SLI is useless and should be removed for the sake of better cooling, it still doesn't work the way you would want it to.
We can't get the RTX series into a notebook due to thermals, power delivery and the die being huge.

you clearly never have build your own cooling solution hence you have no clue about the difficulties that arise.

If you think it's so easy, then go ahead, create a cooling solution that will cool down a 9900K + 1080.

 

You said it cant overclock, it can.

You said it can't run a 9900k, it can.

You said 5.4 can't be done, well it can at least to validate CPUZ.

I have never ever said its equal to the best desktop motherboards with their 12+ phase 600A vrms etc. What I have said is the P870 is about as good as a mid-high end desktop motherboard. That I can pick up and put in a backpack. You can still get a healthy overclock to cpu max, on a mid range desktop board.

What would be more meaningful is a discussion of how close a notebook has to come to high end desktop systems to pass the danishblunt test.

 

Here's Linus' video on the subject.



He's far kinder to the 9700K than I would have been, though I'm sure some of his attitude is tempered a bit because of those sweet Intel dollery-doos that come from both monetary sponsorship and free high-end computers they pay to get built for him.

 

You are 100% correct on all points. +Rep

A whole lot more is possible than some are willing to admit.

Yes, that is exactly what I was referring to. Space and volume are everything. Big things can't fit in little spaces and you're not going to have good cooling with anything thin and light. Just ain't gonna happen because it is not possible. You need twice as many heat pipes, radiators that are 200-300% larger and fans that move a minimum of 5 times more CFM with quadruple the static pressure than anything currently available in a laptop fan that I am aware of. And, that might be good enough for overclocking without AC as long as you don't try to get too crazy with the clocks and voltage.

Otherwise, plan on buying a portable AC unit like some of us have been using for many years. Personally, I have no issue using a portable AC unit for benching and overclocked laptop. That has served me (and others) very well for a very long time. You can also use it with a desktop for cooling and enjoy a cooler work/gaming space. The other thing that is awesome about it is that it requires ZERO modding. There is really no downside to having a portable AC unit, LOL. Or, you can move to a cold place like Brother @Papusan and bench outside in the winter time.

Since I have abandoned laptops and gone back to desktop, there have been a few ah-hah moments. Cooling is the most important thing for overclocking, and most of us already know that. But having the best air cooler or an elaborate liquid cooling system for a desktop isn't even good enough if the air in the room is hot. It might take a little bit longer to heat up the water in the loop, but it will get hot, and the warmer the room is, the hotter it is going to get. And, all of the parts that are not cooled by the liquid loop are also going to get hot and become an impediment before you're ready to be done benching for the day. Having a cool work environment is essential no matter what kind of computer you are overclocking. I never actually realized how effective and awesome the AC cooling actually was until I started relying on a water loop. The chilled air from the portable AC keeps everything cold.

Even having a chilled water loop leaves some components that are not in direct contact with it with room for improvement. For now I am using a room fan running full blast to assist in cooling the back of my GPU that doesn't have water cooling. I may try to fabricate a water block to replace the back plate on my GPU so that both sides of it are liquid cooled. I am also going to incorporate the GPU into the chilled water cooling. It already stays less than 50°C, but I think I can squeeze another 100-200MHz out of the core clock if I can keep it at or below 25°C.

You're 100% correct as well. And, it's not hard to understand. Some either don't want to or they have a weird anti-Clevo/BGA loving agenda of some sort. +Rep

 

There's no need for either the 9900k or the 9700k for gaming, the 8700k does just fine already for much lower cost, power draw, and thermals.

Yup, you nailed it. Removing SLI simply gives them a lame excuse to compromise and cop out on something else by eliminating the extra space instead of using it constructively for more robust thermal management. +Rep

Those would definitely be nice enhancements. But, effectively cooling a heavily overclocked CPU on air with normal ambient temperatures is going to be a challenge regardless of the platform. The platform simply changes the difficulty of the challenge. But, better is always better. Nothing is perfect. +Rep

 

@Mr. Fox, I was correct a few full moons ago, can you give me a +Rep too

On a more serious note, I am looking forward to seeing a 9900k in a laptop, the heat alone is going to be a challenge

 

I wanted to take the time to discuss the evolution of cooling in the 870 series.

We first had where if you ordered a single card in the machine, you would get the T-shaped heatsink for the GPU and the GPU did not have the part, when with two cards, coming over to borrow some of the CPU cooling.

We then had the additional part for the GPU that came over and needing mods or thermal pad so that there was better heat transfer over at the CPU side.

Some went as far as getting a flat heat pipe to run along the back sinks to equilize the temps and heat dissipation between components.

We then moved to the vapor chamber designs on the 870 series, then one member attached metal shims to the heatsink (I think this was plebhawk/hue/etc.), but that may have been the sinks before the vapor chamber.

Of course, foam was added as a barrier and LM used, etc.

But, since we have gone through so many designs, is it so unreasonable to think of a single GPU heatsink with vapor and reaching over to share with the CPU or using a flat heatsink to spread the CPU load with the two other places to help out on the heat? I really think there is a place for this.

And to play Devil's Advocate, as is JB at this point, the TDP, hence the cooling requirements, would remain the same. If there is a way to get the single most powerful GPU in the machine, I see value, especially with the abysmal failings of Nvidia on maintaining support for SLI, and the abysmal showing by game developers for mGPU performance in DX12 titles, etc. As such, some consumers may see a value of the XX80 Ti series over a dual card setup. And, considering the TDP, you could not do it by cutting out the center fan or making the machine thinner. In fact, it would make more sense to offer it as an option like the first T heatsink and ability to share heat from the CPU. That could mean making it slightly thicker to add the flat heat pipe to share the load.

 

this smells too much Azor too Poppy

(all Alien employees get a free one, no doubt)

I'm looking forward to Fazor's attempt to place dual-2080Ti + 9900k in the new Aurora R8 desktop at the end of this month

Trick or Treat: "Aurora R8 will offer 600w of power dedicated to the graphics alone + 120w for overclocking with liquid cooling, all while managing to be smaller than the last gen". If Fazor sticks with the same (multi-rail) 850w PSU + budget 120x30mm wide radiator, that's a hotbox I'm dying to see

edit: yes, 2080Ti's would be limited to 300watts of pull by the PSU & yes, according to above, only 120w available to CPU (25w over 95w TDP) to 'OC' their toy desktop

According to Anandtech 9900k review, 95w TDP is just the PL1 state, PL2 is for Turbo, rated up to 210watts. Aliens will have to gimp the Bios, put a governor on it lest the PSU trips off. And no, Aurora R7 Z370 owners will not get a Bios update to run 9th Gen Z390 products

Spoiler: Smells Like a Cash Grab

 

really disappointed with MSI i mean it made sense because they reduce the cost by using same chassis and pretty much everything else. a big/thick laptop like that, they should at least opt for 3 fans instead of 2 fans. on MSI titan GT80S and beyond they really had great cooling, thats what WT75 should have been.. instead we get 1 GPU and 1 CPU 2 fans, 17 inch, such a disappointment.

i followed the 870 line up on each version so i know the run down. i didnt get the earlier versions for a couple of reason, 4 cores only and crappy CPU cooling, where GPU heat was directed towards CPU side with dual GPU config. i only opted for 6 cores 8700k because of the improved CPU heatsink and more cores, 14nm++ binned cpu, and pcie SSDs thats about it otherwise i'd still stick to p570wm.

 

With that, I meant no offense, instead proffering a situation where they already did something similar in the original iteration. Implementation being any good is still in question. But what is being asked is not as outlandish as some may initially think.

Plus, as many others pointed out, the power delivery and other aspects really need redesigned at this point on that board.

 

the plan at this point is, wait for them to offer a binned, delid LM + sanded 9900k. put it into laptop and turn off HT.. or no upgrade.

 

Wouldn't the 9700k then be a better starting point, since you are planning on disabling HT anyway...much cheaper anyway.

 

To build on that, the 9700K is a side grade from the 8700K. So, even though more cache on the 9900K than 9700K, it will not overcome the cutting off HT and thereby being about an 8700K. It calls into question anyone considering that if upgrading from the 8700K on that platform.

And that is before going back to the above point on power delivery by the motherboard.

Sent from my SM-G900P using Tapatalk

 

no, the whole point of getting 9900k is for the extra cache. im a cpu guy, if 9700k is somehow binned better than 9900k then i wont bother getting it at all unless we are talking about 5.5ghz sl sample. i got programs that will benefit more from cache than having HT. browsers are good examples.

also, this isnt ryzen. ryzen going from 6c/12t to 8c/8t (if theres an 8 core 8 threads processor from AMD) then it isn't worth it. ryzen's SMT is better than intels. intel 8c8t would still beat an intel 6c/12t

 

we need some sort of laptop cooling pad that can bring temp down to like 10c.

 

Are you comfortable sitting in a fridge?

 

Sitting the laptop on top of the outlet of a portable aircon unit is how johnksss, mr.fox & co get their ridiculous bench scores with the P870

 

So, this clears up that. You have no heat issues on four phase boards due to throttle.

Sent from my SM-G900P using Tapatalk

 

u should probably have that message changed to linus cant figure out throttling.

 

Yes, but that also effected others, like OC3Ds numbers.

Also, I'm not as sure if anyone goes to LTT on performance reviews. I watch them regularly, but I often refer to other outlets findings, personally.

But, simple mistake and now confirmation of why these reviews have disparate results. Since AdoredTV calling out journalists in the tech press last year and early this year, we've seen more responsiveness by the tech press to address when findings so not produce expected responses, had more attention given to bios settings like MCE and performance boost overdrive, etc. So I don't want to bash any media outlet, rather say that we have the culprit and now have a better understanding of minimum specs to run these chips.

The current throttle reducing speeds to 4.2GHz on a 4 phase board suggests having the extra cache may not create as much of a benefit as the overclocked 8700K in the 4 phase clevo laptops.

Sent from my SM-G900P using Tapatalk

 

I thought the P870TM has 8 phases? On the WT75 I found 10 TI87350D buck converters but they seem to be in an 8+2 configuration to support the GT2 power when the system is running in hybrid graphics mode.

 

theres no problem with 4 phases at all with 8700k. if u get a 9900k onto a similar power consumption then it'll have no issue (disable HT, get a better binned chip etc). johnksss and few others got it to 200w with 8700k on clevo. its not so much as only 4 phase, its just settings they needed to do to NOT throttle which they aren't checking. you simply can't use their findings to just say 4 phase boards aren't good enough. more phase the better, and clevo is working just fine.

so no, their video didn't prove anything other than their mistakes.

 

I will admit I could be wrong on the P870 series, but I know the P770xM machines have been 4 phase for awhile, since my ZM and through the DM series at least. Also, did you check to make sure they were properly driven, meaning that they either had the doublers or had a chip that supports 8+2 on driving those, or did you just add up those components and assume?

I pulled up the datasheet ( http://html.alldatasheet.com/html-pdf/465708/TI1/CSD87350Q5D/378/6/CSD87350Q5D.html), which didn't know the version, but looks like a 20A max at 1.2V. I'll let your look into that a bit more, but it sounds like more full analysis needs done for what it supports.

Citing them using AC cooling, which would help keep the temps on the VRM in check due to very cold air, freezing in fact, blowing throughout the system should leave people with some pause.

As to the overall proposition, is that why most Z390 midrange and high end boards use true 12 phase setups or 16 phases? Also, so far everyone that has not had issues on heat with the 9900K came directly from 4 phase boards, which were shown to current throttle and drop clocks of the chip, at least in one examination, down to 4.2GHz. And to cause the throttle condition not to occur, you need to examine the Amperage on those chips, the heat output, and the cooling on the VRM, which is constrained on the laptop form factor.

But, feel free to ignore someone pointing out a possible issue and what needs done to investigate it. If you are unwilling to even acknowledge the possibility of what may be occurring, then what comes cannot be complained about later due to your choice to ignore things on the front end.

 

So, cannot read the component numbers in these images, and the back board image I have is of a P870DM board, but this gives an idea.



As you can see, there are four potential drivers that could be doublers that I cannot read, but only 4 inductors while the capacitors are on the back of the board.



Here, you can see the control chip and the capacitors. I would bet they are using a four phase just on the inductor and capacitance, rather than it being an 8-phase by four with doubling. But, since I cannot read all the info on the chip numbers, deeper analysis alludes me, plus I am nowhere near as good at this type of analysis as others out there. But, I am trying to give more information, including my analysis, to allow a more informed decision making process. Please, by all means, if you can show that I am wrong, do so and educate me.

 

@Khenglish is probably one of the few who have most knowledge about the power delivery system on Clevo P870 models. This is one of his posts about the topic... http://forum.notebookreview.com/threads/clevo-overclockers-lounge.788975/page-1639#post-10793399
