If your 8700 can keep 95w stable whole time you should see you as lucky.... Normally locked to 65W (PL1) in prolonged max Cpu utilization.

Yes, given the same power the 6 cores wont maintain the same clocks as the quads under stress tests.

 

If you don't want it to power throttle after 30s, you can raise package power long or increase turbo time limit. You might encounter thermal throttling however.

If your CCC doesn't have the 'CPU memory overclocking' section, then you need XTU to enable XMP.

 

yes bingo!
installed XTU...seems to be the best for this config...since it is also seems to be everything enabled about all multipliers….
Look here:


it seems the more "turbo boost power max enable" increase the throttle frequency is minimize...Now I'm on 83.7w...and almost 20 minutes of full prime the temperature seems good around 75 degree...4-4,1ghz...and a vcore very low(maybe I can try to lower it more!) ! do you think I can increase more than 83w?
with this temperature and frequency now I'm sure the cpu is delidded..

the ram XMP is now setted to 20x so now ram running 2.666 as they are rated for! (do u think I can try this g.skill rpjaws to increase multiplier or better to lower latency?)

 

Go for it.

 

several things to maximize performance:

- lower "power boost power time window" to minimum (should be 0.25 seconds) to get more stable boost clocks. contrary to what most people think, its best to MINimize this setting rather than MAXimize it

- maximize "turbo boost power max" and "turbo boost short power max" all the way up to unlimited. no worries, the CPU will only take what it needs, it helps immensely to stabilize turbo clocks

- when undervolting, set all core bins to the same multiplier (so for stock, best to start off with Core 1x to Core 6x set to 43x = 4.3 Ghz)

- test VCore stability for 30 min in P95 setting 1344k, 12 threads, run FFTs in place and for 15 min. cycle time. if the setting is stable for 30 min, its good for everyday usage depending on how hard you plan to hammer the CPU for everyday usage, u can either use P95 with or without AVX (as per the added command line u already posted)

enjoy your new system!

 

Hi Guys,
Any experiences with 8700k (stock or OC) + 1080 in 751tm1? I would wunder if it works on stock clock, and with what temps...
thx

 

You will need @Prema firmware and delidded processor.... https://www.notebookcheck.net/Euroc...0-Clevo-P751TM1-G-Laptop-Review.281388.0.html

Fyi... Eurocom doesn't offer Prema mod firmware.

 

Hi, why do I need prema bios? (of course its always good, but with stock bios 8700k and 1080 does not work?) I am curious about the temps if the laptop manages both....
thx

 

Read the review. Take a look on Stress Test + Energy Management. Prema Mod firmware correcting this behaviour. And you need delidded Cpu to maintain best possible temp even stock. It's a 15,6 inches chassis with 6 core desktop Cpu, bruh. It's what it is.

 

@woodzstack

 

Thx I hve read. Prema bios os for the mb i assume not for the 1080.
If i understand correctly with stock bios the 1080 and 8700k works but it will throttle... same with the previous models ( i have a 775dm3)
Right?

 

Yes, expect some throttling with stock sBios with full load on Cpu/Gpu (undervolt + delidding will help). And Nvidia has locked everything out for Pascal. There is no mod vBios for Pascal graphics.

 

I know, I have 1080 in my 775dm3, however I do not want to overclock the vga. For cpu stable 4,6-4,7ghz would be nice without throttling...

 

The stock BIOS shouldn't throttle unless you're pushing for 4.5+ overclocks in CPU stress tests and AVX workloads. Gaming at higher clocks is fine.

Edit: This is an educated guess, I only have 8600K not 8700K

 

THX for the answers guys, I will update you what my experiences are... Still love my little MSI16L1X

 

Thanks for mention @NIGHTMARE

This laptop has decent sinks, the temps at stock, like 4.2Ghz is very low, but if it's not delidded and just pasted with ICD7 you can still expect as high as like 80-90C when in load for a while. The 1080 can hit that easily, you need to paste it like a pro, and sometimes even a few times, to get the temps under control. However best I've seen is keeping the 8700K at 5.0Ghz and the 1080 at stock, and getting like 85C when playing a demanding game all day. When not doing something demanding and lower CPU to 4.5Ghz and again stock 1080, then the CPU can be at best in normal use like 65-70C and maybe the GPU 80C (but only when gaming, like Chrome is not going top put a load on your GPU, you understand...)

 

Considering how compact the system is that's pretty impressive that's achievable. I just wish intel would solder at least the K editions.

 

many thanks mate for your advices!

another question: what about the battery maintenance? I mean: in my previous Dell Precision I had an option in the BIOS that I flag and that was for an "use of the battery with the power adapter connected almost every time".
In this new PC there are not options about it. So I'd like to know if there is some alternatives to take care about the battery and hit the long possible life.

Thank u

 

Enable FlexiCharger in the advanced chipset menu and set the start/stop charging % threshold.

 

Is it possible to replace the 30 pin screen connector in this unit with a 40 pin to open the display replacements possibilities with all the new IPS 120/144Hz?

 

Yes it should be possible, the existing 40 pin from the KM and DM should work IIRC.

 

Do you recommend this model to handle the 8700K with the a single gtx 1080 rather than the P870TM1? what is my best model for that?

 

If you plan to do heavy overclocking, and the size difference does not matter to you, then the P870 is the better choice and will cool much better and open up more performance.

I've had two of the P870 models int he past and they cooled well and seemed much quieter to me even at max fans. I chose the P751 this time because I really wanted a 15" and still have (most) of the performance of the larger chassis.

 

I spent the last 2+ years trying to convince our costumers in local market with Clevo DTR machines, I need to consider the price as the main factor so I can penetrate the Saudi market with something they consider it unknown with no local warranty.
Most of my Costumers/Friends are Engineers, Programmers, designers or students, they are not overclockers, they only needs the performance to render or gaming. So if this model will give the most of the performance needed to their work, so I have to show them this size as well and give it a try.
Thank you for your advice.

 

Realize I have only had my system for a few weeks, plus I have my CPU delid'd by HID and I don't likely push it as much as some do (Mr Fox). But so far I feel it's a very solid machine and at the same footprint as my 2 in 1 laptop, only thicker, it absolutely crushes most (all?) other 15" laptops. The mxm gpu and socket cpu, 4 drive slots, 4 memory slot are all bonuses. I like the way it can be fully powered off a single power brick too.

 

The heat is the big challenge for all 15" models, specially with the 8700K and the 1080.

 

Get the P870 if you don't mind the size, but if you want something more portable, the P751 seems to handle even basic OCing fine when delidded and additional cooling upgrades (i.e. HIDEvolution's upgrades). The P870 is a lot bigger and will run cooler, though ideally you want to delid that too and upgrade cooling. Overall, I didn't want to go above 8 lbs laptop size, hence why I chose the P751.

 

What would you say have been the drawbacks so far? Which drawback was the most expected and which was the least expected?

 

Biggest drawback that I expected is CPU overclocking ability. I have played around with 5.x Ghz to varying amounts but the boost clocks can only hold for so long before heat eventually becomes a problem, at stock settings it runs cool, and you can run a little above stock and still be ok (currently have a 4.8 all core throttlestop profile if I want a little extra punch from the stock 4.3) but you will hit a limit earlier than a bigger better cooled chassis.

Biggest drawback I didn't expect I would say is the fan noise. When I had it side by side with my P870, the P751 was louder, and still doesn't cool as well. I figured it would be the same loudness, or be louder and cool better, or be super quiet and not cool as well. This could be just my ears playing tricks on me, no scientific data was collected. To be fair it is still much quieter and less annoying sound than my Aorus X7 DT V6 was.

The main draws for me, and the reason I went with this machine was that I wanted the smallest machine that could house a desktop 8700k and 1080, along with loads of memory and drive configurations. The P751 excels at these requirements as long as you understand the thermal limitations of such a small machine and use the absolute best thermal solution you can (I paid for Delid and glad I did).

I can encode my video rips so much faster than the 6820HK I was using and much quieter config. The thickness does not bother me and if anything makes it feel stouter. The smaller footprint opens up a smaller sleeve to carry it in and smaller lapdesk that I can use at the recliner or in bed.

I love having 10TB installed SSD inside my machine, I was going with a 12TB config but the last 4Tb SSD I bought turned out to be a fake so I just went with what I had on hand.

Of course tons of ports and full size SD card slot are becoming harder to find so they are welcome to have as well. The 144Hz panel is great although I use an external much of the time. One final note is that I like the tear down of the P751 much better than other laptops. No hard snapping of panels off, they slide off nicely and you can even pop out the battery if you want. It is designed well. Only reason to take the keyboard off if to access two of the four memory slots.

 

Out of curiosity, did you do the sillicon lottery CPU from HID or did you just get it delidded? I am really curious how my temps will be with the lotteried processor I ordered from HID. Hope it's worth the extra money. Hoping the lotteried processor will run cool enough to match similar temps/performance as p870, but I doubt it.

 

the P750 series is quite powerful at powering and cooling high-end components sure it needs a bit of tweaking here and there, but so do all Clevo machines.

 

I'm not sure if this has been raised before, but did anyone else have a problem with the display not showing up again after leaving the computer on idle? I've noticed that when I had to leave my laptop on overnight (because I forgot to charge my mobile phone), I'd wake up to it not having any display at all. Sometimes the fans might be running loud which is why I'm thinking that there's something that's wrong with my unit.

I'm using the "Ultimate" power settings, and I haven't really done anything with the default SpyderUtility that came with my unit. I have my laptop's display turn off after 45 minutes.

Same issue happens when I close the lid where it's supposed to be "[doing] nothing" as per the settings.

 

I went with what was the lowest optional upgrade which was 4.8 with delid. It was a minor cost bump and at least I wouldn't end up with a bottom of the line ones or at least that was my thinking anyways.

 

@yrekabakery
guys a couple of questions:

- suggestion for a good thunderbolt hub that could be replace a docking station for my p751tm1G. I tried one from amazon in discount but i'm not satisfied. any specific brand/model that is good to suggest?

- about audio: how to take maximum advantage of Sabre+Burr brown chip through my headphones? for example I suppose its sabre dac is able to native support dsd format. Am I correct? if yes how can I configure (for example foodbar or any other suggestion is fine) the player to be sure to get a bit perfect dsd reproduction without resampling or other? in foobar I know there is the "ASIO method" but in this case if the DAC is already able to play dsd natively, maybe I don't need ASIO method...

thank u !!!

 

I found the limit of my 190W GTX 1080.

When playing Sleeping Dogs: Definitive Edition and PlanetSide 2 at 1080p with 4x SSAA, in spite of a -150mV undervolt, it's still hitting power limit and dropping below 1800MHz and 900mV. In other games, it never drops below 1848MHz (stock boost clock) @913mV.

 

strange that ure hitting any GPU limit at all at such a low resolution...

PlanetSide 2 is a CPU and GPU hog because of the size of the map and the number of players. Still interesting that those are the games though where he's finding throttling though since it's such an old game now.

 

I still think, that battlefront 2 with no FPS cap is the real test, as it runs both the cpu and gpu on 100% all the time giving nightmare temps

 

May i ask some? I just read this article and notebookcheck said this beast have CPU drop rate while playing game is it true guys? https://www.notebookcheck.net/Schenker-XMG-Ultra-15-Clevo-P751TM1-G-Laptop-Review.290330.0.html

 

It all depends. If you get your CPU delidded and apply LM, you have a solid temps if you keep 8700k to low OC.

 

Is that old school battlefront 2 or the newest one?

 

The new one!

 

But in their review they only use i5 8600K and GTX 1070, i think it have power management problem coz they said it have over 300W power consumtion.

 

1080p with 4x SSAA is just as demanding as rendering at native 4K resolution.

On the stock BIOS, I had no CPU throttling when gaming, even with the CPU overclocked. You can check my videos here (every one except DX:MD was on stock BIOS): https://www.youtube.com/playlist?list=PLHmyv3RnaT3MauMG_tLaeaVgMY4b2XQJk

 

With that combo you can get away during normal day to day use (other than benching or heavy loads like AVX2 etc).
For 8700K/1080 combo that's a different story...

 

The cpu run without undervolt. You won't lose so hard in the silicon lottery that you ain't able to put in an ok undervolt for stock clocks or even slightly overclock.

 

Interesting and also confusing considering the Eurocom Sky x4c with 8700k / 1080 only comes with a single 330w and it didn't power throttle with this benching and review. https://www.notebookcheck.net/Euroc...0-Clevo-P751TM1-G-Laptop-Review.281388.0.html

If I wanted to overclock the CPU to 4.9 (sillicon lottery HID build), would I pretty much have to have dual adapters? Is it possible else to get two adapters and combine for additional power for p750 8700k/1080 combo units? I actually ordered two adapters with mine, but I don't have a combination adapter like what you can get for the p870 line. Is p750 compatible? Also, I believe the 330w adpater is rated for higher watts in surges right? It's just 330w constant?

 

Well I don't think you will needed two adapters to do the overclocking but might be heating will concern for you. Because I was on same boat of P750 but after looking dual vapor chamber I changed my mind and purchase P870TM1-G aka X9C from @woodzstack, he done the all custom jobs for me. You can ping him here or his discord channel.
