*** Official Clevo P870DM/Sager NP9870-G Owner's Lounge - Phoenix has arisen! ***

Thanks again! I learn a lot from you. The ram has to be overvolted to 1.3 to make it stable though.

 

when running the AIDA64 test it peaked at 94 Celsius while 4.4 peaked at 91 Celsius not too bad of an increase during really heavy stress but games like doom and BLOPS3 aren't going over 60 Celsius.

What's the highest you can go with it still lidded? If i was gonna delid i would buy a second 6700K and delid that!

EDIT: I think 4.5GHz will do for me but will still test.

 

That depends on the SL!

From what I've read so far 4,5Ghz seems to be the sweet spot for most 6700k's undelidded before thermal throttling occurs. Of course you can stretch that with CLU to 4,6Ghz maybe....

 

I have only tried 4.8Ghz but it was using adaptive-static. @Mr. Fox 's settings use adaptive with offset. Not only it gives better results, it has better temps too. @bloodhawk managed 5.0Ghz

 

fair enough. since i won't be delidding it i'll stick with 4.5GHz ... no dramas and so far but will still keep checking.

share the bios settings and whether it's delidded or not.

 

Use these settings with your 45x4 and see how they work.

 

Mine is delidded. I used @Phoenix 's settings for 4.6 (on the OC page), multipliers are set to normal (42-40-40-40). I then adjust the multipliers using TS 4.8Ghz is not that stable for me though, that is why I have not posted any benches with it.

 

I find it strange that the 6700k only supports 2133mhz RAM as per the Intel spec yet you can use faster RAM without issue at the original RAM's clock speed.

It's the same with all overclocking. Intel guarantee a certain base level, anything you can get beyond that is up to you.

With memory they are always conservative with binning, there will be one or two weak IMCs out there that may only reach 2133mhz.

 

4.5ghz seems to be doable for me so far. Temps in games are still good.

Thats great to hear. But most games dont push the processor all that hard.
If gaming is all you want to do, you should be A-OK!

 

I am still waiting for the 2400mhz ram to come in so I can see how that might affect it.

Wont notice anything going from 2133 to 2400.

 

Ok, though having 2 16gb sticks should suffice with extra space for more sticks in the future. So long as they work it's all good.

What with your old ram? Spare parts?

 

2133mhz RAM from Samsung. 3 8gb sticks. The dream is 64gb.

You must be quite ram hungry then, what do you do that eats it all?

 

Please take a peak if you own P870!! http://forum.notebookreview.com/threads/clevo-overclockers-lounge.788975/page-437#post-10302359
Use your voice and say your opinion about premium performing laptops so we can try to stop BGA Turdbooks!!

 

If reviewers keep reviewing stock Sager BIOS/vbios versions, it's not going to look good to enthusiasts reading these reviews - that don't know about NBR, maybe point out this a few times with links back here, and to the Prema list of vendors.

Why won't Sager adopt the Prema extended BIOS/vbios for all shipping units?

Maybe a de-tuned Prema version, tweak it a bit to meet Sager's sensibilities, but not so neutered as the stock one is now. Something that will look good in reviews, and for all the buyers when they unbox it and start using it.

 

I have already voiced my opinion @Papusan

 

the idea of non bga itself even with stock bios is better already lol.

hey brothers, i was under the illusion of the new gx800 and gt83 with bunch of cooling and performance improvement will actually be great, until i took a look at cpuz for gx800 preview. 4.3ghz at 1.455v!!. that woke me up hard now i'll just wait patiently for clevo's new laptop.

 

The Clevo's get shipping with "hot" CPU voltages at stock too, that's why everyone undervolts so far, into the -200mV range.

All the makers do it because they think it stabilizes the CPU over a larger range of use.

Plus it has the benefit of running hot, putting a damper on OC'ing, at the risk of complaints from users - requesting re-pasting.

Those overvolted CPU's may have shorter lifespan's, but the failures should be outside the warranty period - so they don't worry about that.

Always undervolt, tune, your CPU / GPU for long life balancing with best performance.

So you can tune the GX800 CPU when you get it, reduce the voltage to something safe, and run it at 4.0ghz, which is the optimized point of best performance with the least chance of long term damage.

It looks like the 6700K's optimal spot is nearer to 4.5ghz, or?

 

6700K ~ 4.5/4.6 GHz. Max 4.0 GHz for 6820BGA

 

And, it's not just the 500-600mhz faster operation, it's the 2x power handling at that speed that makes it so much higher performing in benchmarks, games, and apps.

 

See Max processor temp in a wimpy Firestrike bench(Auros X7). Have you headroom for higher OC on that JokeBook's 6820BGA? And if you put on 1,45v who is the normal for this junk at +-4.3GHz? Make Fire? A unlocked voltage bomb!! Created by Intel!!

 

My 2 16gb sticks are in the mail.

The review never got the explore the amazing cooling capacity of the P870.. Something that still amazes me. Comparing it to my previous formidable Alienware m18x r2 at similar clocks I'm well impressed.

Man it's so nice to have a honest socketed CPU that can be fully exploited. @Prema your BIOS absolutely rocks brother!

 

@hmscott, ^ what papusan mentioned.

honestly those design were cool, gx800 water cooling i could seriously take advantage of that, gt83 would probably be amazing as well. at the thought of 4.3ghz and 1.455v with watercooling, thats similar to 4.3ghz 1.25v air cooling. all purpose of high end overclock is defeated with such a garbage hardware.

i wouldnt mind soldered chip if it's capable of 4.8ghz with decent voltage, its easy to know coporation wants control and profit. control is one thing, buying junk hardware while paying premium is a different story.

 

Yeah, overvolting a 6820HK to run at >= 4.3mhz is like teaching a pig to fly by strapping a rocket motor to it's ass, it's not going to end well for the pig

 

gx800 watercool, can run cpu at low temp, but one has to remember that a silicon will degrade if the voltage is too over-spec, regardless of the temperature


edit: does anyone have an updated list of prema parter? thegh0sts ordered a metabox and got prema vbios/bios but I don't see metabox on the prema website.

 

That's a thin and light machine, a desktop chip in that machine would fare worse.

 

The silicon lottery is one thing for socket chips. But with chips soldered on motherboard? Big No thanks!!

Yeah. That pig will be well done Bacon I hope he come down in my garden!! I'm hungry

 

We weren't doing a comparison in this particular case, just observing the absurdity of pushing a 6820HK to 4.3ghz in anything, for every day use.

Earlier we were talking about 6820HK vs 6700K in an Asus GX800 watered cooled monster, maybe you mixed the two up.

In the GX800 at least the Pig (6820HK) will be getting a constant Rocket exhaust cooling water bath when plugged in and OC'd.

It's also true that a 6700K would be tough to cool in the GX800 laptop too.

A 6700K is just a bit too hot at 95w TDP, but the 6820HK is only 45w, we need a CPU that can sustain 4.5ghz @ 65W.

 

If you liquid cool properly like the little zotac camp outer you can cool an i5 desktpp and 980 desktop (mxm) off a single 120mm radiator. It shows the weakness of water cooling in notebooks.

 

I prefer to think of it as the advantage of Desktops, but 6 of one... half dozen of the other

What about a large flat and thin radiator, housed behind the screen. Plenty of volume and air exchange area.

Who's gonna try it first?

 

The other 16GB memory has arrived, however I'm having trouble making the 32GB work together. Here's what I've done:
1. slot 1, both memory works individually.
2. slot 1 & 2, 1 & 3, 1 & 4, 2 & 3, 2 & 4, 3 & 4. No post. Basically all the slot combinations, do not work.

Any ideas?

 

Are they different modules abs have different timings ?
Check the OC thread for Mr Fox's post. I'm on the phone, can't link it. Should be in the last few pages.

 

They are exactly the same GSkill Ram which I had problems booting to 3000Mhz before.

 

Ah yeah, then you gotta do a full CMOS/NVRAM clear.

 

Yes, I also did that. But it did not post, I'll try it again tomorrow morning. Thanks for the reply man.

 

Weird. I think @Mr. Fox mentioned how @j95 got his modules working. Lets wait for him to chime in.

 

It is confirmed that the Sager NP9870 has been discontinued....

 

https://www.sagernotebook.com/error_message.php?product_disabled=

"Unavailable product
This product is unavailable or temporary disabled."

Maybe that means the Pascal P870 is soon to be announced

 

That sucks. I was hoping that the Pascal cards are plug&play after a bios update.

 

Ouch.

But means, there is a refresh coming out soon (i hope). Its gone from almost every website.
Disappointing though, if they decide to change the entire system ,its barely been a year since it came out.

 

Well it had to happen. I'm guessing this is a neat way of telling us the refresh is coming and some MXM modules to boot. I'm pretty sure the successor isn't a complete redesign... I sure hope not.
I'm foolhardy counting on some plug'n'play-ish action.

 

Yeah. Either ways, this baby can fit the fattest ones out there.

 

The P870DM refresh should be the same chassis, just an extra usb 3 type-c port and probably improved cooling.

 

And the Norwegian Clevo reseller lower the price now!!

 

larry put in a word for us to clevo 6c skylake-E laptop thanks
