Hi Donald, I sent an email to you regarding my laptop query. I hope you recieved it. Thanks!

 

by the way I saw an article saying that NVidia reduced price for the gtx 1080. would be nice to see the corresponding changes ...

 

Replied.

 

That is for desktop nVIDIA GeForce GTX 1080. There will be no price reduction on the laptop nVIDIA GeForce GTX 1080.

 

if I remember right everywhere they say that there is (almost) no difference between desktop and mobile version.

 

Performance wise, yes but mobile GPUs have to be engineered differently. They also don't have the economies of scale that desktop parts do. Hopefully this will change if AMD can come out with a performance competitive mobile part.

1080 desktop cards are dropping because the 1080 Ti is on the way out. AFAIK there isn't going to be one in laptops (and I could be wrong), so I would expect the same push down on prices because of a new king coming to town.

 

You are not wrong...there will be no nVIDIA GeForce GTX 1080Ti for laptops. NVIDIA is reserving that for desktops only. So, while it was nice while it lasted...say goodbye to "With the introduction of Pascal, laptop GPU’s performance is now virtually identical to desktop GPU’s" May it rest in peace.
.

 

Thank you nVIDIA for bursting our bubble. it was nice while it lasted

Now we can't say we have the best GPU until next gen, see you again and thank you for playing

 

Oh come on now, we are still plenty powerful are we not? Especially us current/future SLI 1080 users!

It is still kind of when you have the same name although the desktop 1080 is getting faster memory.

The issue with the 1080ti is the beastly amount of power needed, only the NP9873 type machines could handle a single card.

 

Come on guys! Dual 1080's are awesome. I'm loving mine. I'm actually GLAD the 1080 Ti's aren't coming to laptop - means in this form factor my beast is king of the hill for a few more months. And frankly - I know no good gadget geek should ever say this - but right now I have more power than I need.

I'm still remembering the shuddering framerates of my old Alienware 18. Buddha says all unhappiness comes from comparison - I DO compare, just with the hunk of junk I had last, and boy, does that comparison make me happy.

 

I'd have loved to have seen a single 1080ti card take up both slots and both AUX power cables for some serious fun but the 1080 SLI setup would still out bench it which would turn some people off.

 

Speak for yourself. My setup will handle a 1080N TI SLI perfectly fine.

 

A noob question, I noticed that quad channel memory mode is more expensive that a dual channel having the same memory capacity. What is that advantages and benefit of having the quad channel memory. Is there a noticeable improvements in games or benchmark?

I saw this 2015 article http://www.pcworld.com/article/2982...ing-truth-about-their-performance.html?page=4. Maybe there are some improvements during skylake reign?

 

Sure at stock, but the core comes alive when allowed to run more freely around 40% if you don't limit it. I'd take that over dual cards running at stock for real performance.

 

Thank you @Phoenix for customizing my laptop. What would I have done without you??

Be smart, be like @Phoenix

 

You could have asked @bestbuy instead!

depends on the applications, if they can take full advantage of it. normally by having dual channel and high bandwidth, it is enough for most things and you won't see a difference really. its definitely great to have quad channel for software that uses avx extension and uses a lot of cpu cores, quad channel with same memory would be much MUCH faster.

 

Ok, maybe we are not talking the same language here.... Your overclocking skill level and my overclocking skill level are two entirely different things. Where as I take it a bit more seriously than you would. You don't get into the top 20 USA overclocking league by doing the "Sunday Driving" overclocking sessions. You do it by putting in the work to achieve higher. So, this is to say that you might be able to only get that far at stock, but i would get much farther. Although maybe that is not a correct analogy to use since i'm using the "Sunday Driving" method now and sit at number one overall. I haven't did any hard mods yet. Stock vbios/Stock CPU heat sink also and was able to get to 5.2 ghz (7700K) on stock bios. (Just giving some real world examples) Not to mention 5.4 ghz.

If you were saying that to some random person who doesn't know anything about this. Sure I would totally agree, but you are not. You are talking to me. The guy that makes things happen. So if i say i can do it......I can do it. And it sure won't be at stock either.

 

Johnksss@iBUYPOWER I have the 7700k, Prema bios and I'm using XTU. I can get to 5.2 ghz and validate on cpu-z but when I try to use the XTU bench mark. I keep getting a current limit throttling warning. Is there something wrong with xtu benchmark or is that just user error? And need more adjusting?

 

The thing about XTU is...It will pull more watts than any other program you use to bench the cpu...Short of maybe Vantage cpu test. And the CPU needs to be around a certain temp to maintain stability when running.

The current limit can be not enough watts or amps.
I would start at 5.0 ghz and slowly work your way up. That's why you have bclk unlocked. You guys keep trying to make these insane jumps between multipliers without knowing what voltage is actually needed to do so. To much and you crash. To much cache and you crash. Unstable ram will kill you every single time even with having the right voltages.

So start at 5.0/5.025/5.050/5.075/5.1
When it crashes add vcore and keep going till it passes. then move to the next step.

 

Eh.... I wont be surprised at all if people can clock to 5.4ghz/5.5ghz on 7700k. Its is a very optimized skylake. Good Luck John.

I am looking forward to what I can do on a 16L13 if I do get that 7700k.

 

I would.

5.4 is already pushing it, but it will go if we could get past a certain setting.

5.3 was only achieved by one other person, while 5.2 was done by at least 2 to 4 people.

 

:O

Really surprised on the 5.3Ghz part. Are we talking validation or full stable benching? Either ways i expected it to be more common.

 

http://www.3dmark.com/fs/11443116

 

I was referring to desktop side. Without extreme cooling. -0.2-0.3 for notebook.

I am happy around 5-5.1 personally.

 

Ah, ok. Because I didn't get that out of that post. I thought we were talking only about 7700K in these notebooks we have. Desktop overclocking is a whole different world with more options to do greater things. It's kind of why i never even benched my cpu for points because it can obtain better numbers on a desktop board.

 

Pretty much. Clevo can learn a lot from desktop vendors...

 

I have this in stock too. ( X9E3 version)
Will start updating my thoughts and opinions on results from personal testing within the week.
Already accepting orders mind you.

 

I think it's more of a different target then, i'm talking about going for the best 24/7 experience and you are talking going out and out for a benching session.

I get a set of hardware best for 24/7 and push it as far as I can where you go for whatever gives the highest score as IIRC you are not really a gamer.

In this analogy you are a drag racer and I am a 24 hour le mans racer.

 

Hummmm... My 24/7/365 clocks if I chose to use them. (cpu 5.0+ ghz/ gpu 150+/500+) They work for benching and gaming.

Not sure I understand. Pretty much any hardware can be best for 24/7 use and also be pushed....
Correct. I'm not a gamer, but I do play games from time to time. I have yet to need to overclock to play. When that happens I just get more or better hardware for the job.( Kind of why I have SLI now)

As to the analogy you used.....My "drag racer" would be able to compete in your le mans and still win 24/7. Why? Because my efficient setup can run higher clocks with less power consumed all around.
I'm just saying is all...

 

Does hidevolution offer delidded keyboard?


@Phoenix

 

did you get your gt73vr yet? hows does 7820hk looks in overclocking?

 

long back bro

See this: http://forum.notebookreview.com/thr...cussions-lounge.794968/page-476#post-10476650

 

So you are saying your full benchmark clocks are 100% stable, no artifacts or ever a crash with no assisted cooling?

In that case I simply lost the silicon lottery.

 

My full benchmark clocks are 5.1/5.2/5.3 ghz & 200+/600+ gpu
The clocks I posted are not running with ac. No artifacts and crashes other than when i ran the memory out of spec, but since then I have fixed that.

Assisted cooling?
CLU-high quality thermal pads-modded heatsinks-cooling pads-vbios mods and even a/c is Assisted cooling, since that is not how the system shipped. I understand you may not have all these things at your disposal and that is perfectly fine. That is why your 24/7 is lower than mine. I said I was a bit more serious about this than you and that part still holds true. So I can game at just under max overclocks with using a/c-Liquid Metal on CPU & Cooler Master or KPC paste on gpu's. Just under means dropping Memory clocks just a bit since there is not enough voltage for them to run long periods of time at that high. (laptop only)

I have LN/Dry Ice/Water chiller/Single Stage Phase and a host of assorted cooling products. Why would I neglect my laptop? I don't understand.

In the end, I will continue to use ac with my laptop while benching and regular air while not benching or gaming. Why? because undue stress when it doesn't need it is just insane to me.

Side note:
Your cpu is not the problem....

 

I've been playing around with the load line calibration with the CPU but not quite found that yet so I accept that's not tuned as best it could be but the GPUs will not run over around 2025Mhz all day stable even with the extra bump from MSI afterburner and setting the voltage a stage higher and temps are well within range so unless I unlock voltage control on them there is not much I can do on that front.

Sadly I have not had the time to quite go as far as you have but I have shared what I can so everyone can benefit at least so I like to think that has helped some people

 

Before any tuning is to be had. You need to first be able to just set your cpu to 4.9 ghz on stock (extra high voltage) and be able to run a cpu bench. That is your starting point.
You make it through Vantage cpu test or cinebench 115. Chances are real good it will be stable for just about everything else. I messed with LLC already. Didn't really make or break anything.

As to your gpus. You need to be in the "below 38C range. to get as close to optimal as possible. Anything above that you start losing 13mhz at each stage.
22-27 13mhz
32-37 13mhz
42-47 13mhz
52-57 13mhz
62-67 13mhz
72-77 13mhz
82-87 13mhz
90+ 13mhz

This brings me back to efficiency that I spoke of earlier. You have the extra watts, but because your gpus are running well above the optimal temps.....The clocks do not reflect your efforts.
And if you are trying to force the curve on them, you lose a bit more for stability clocks. I have a post with examples of all this. somewhere around here.

Good deal? Also is there a difference in clock speeds on the 1080 without g-sync? Anyone ever ordered from prostar before?

 

My unit just walked through the door. Need to install hard drive. Where is the service manual? the one on the Clevo site is actually the user manual. Easier question to answer, how do I get the bottom off to do the install?

 

Nevermind. I found a video HTWingNut did for the P870DM-G.

 

Spoke too soon. Doesn't appear to be the same case.

Any ideas?

 

It comes off the same way. Just that the first few times its a bit stiff to take off.

 

Sorry to be a PITA, but I can't get it to separate at all. I removed the 9 screws no the bottom. Any suggestions on how to get it started.

 

have you watched linus tech tips he took apart a clevo

 

Watched a different one that actually shows the taking off of the cover. I was able to use plastic pry tool to get it started.

Now to find th M.2 slots.
