*** Official Clevo Sager NP9155 / P750TM-G / P751TM-G Owner's Lounge! ***

The two keyboard screws do not require removing the heatsink on this model. This is a pretty simple job TBH. Went through this process about 5 times this weekend

 

ok cool, with my machine one of the two screws is covered by the heatsink. good to hear they improved on that with this model

 

I was in the same situation (F5 vs X4C), did you understand if they fixed the bad cooling system? I have read that now the X4C does not share heat pipes between CPU and GPU, but I don't know if that solved the problem. That's why I am still struggling with the choice.

In general, I also read that it has a 256 maximum Watts given, it is a smart choice to have a GTX1080 +i7 8700k? (TDP 190W + 95W)

 

only the 17 inch 775TM1 has separate heatsinks for cpu and gpu. the 15 incher is still sporting the unified heatsink design.

So yes, the P775TM1 has the completely separate heatsinks, but that doesn't mean it's objectively better in every way. The P775TM1 has 3 independent heatpipes for CPU exhaust and the P750TM1 has a fourth CPU heatpipe that only connects to the GPU at the radiator. This fourth heatpipe is the primary reason the P750TM1 does a better job than the P775TM1 at keeping the CPU cooler during CPU only loads, even up past 120w. The only other 'unified' portion of this heatsink is where one of the other 3 CPU heatpipes helps exhaust heat from the auxiliary GPU components.

My point with this is it depends on what is most important to you. Both the F5 and the X4C will perform similarly in games (I have both) but the CPU performance on the X4C is insane for a 15". I care much more about CPU cooling because most of my workflow relies on exclusively the CPU and I only have a 1070 as the GPU. The P750TM1 was a better fit because of this. A delidded 8700k with 6 cores at 4.6ghz and undervolted in a 15" laptop is a dream for me...just as the P750ZM was when it was the first 15" with desktop CPU

One last thing, I would get an F5 immediately if it had they updated it with the 8700k. I like that machine overall better, but since it isn't being produced, the X4C is fantastic and I'm quite happy with it.

Take a look at the heatsink pics:

P750TM1 (4 total CPU heatpipes, 1 shared across auxiliary GPU components, 1 exhausts with GPU radiator)

P775TM1 (3 CPU heatpipes, all independent from GPU

Spoiler

 

Thank you, I think i will go to the x4c then, because I prefer to have a little extra juice in the CPU.
About the cooling, since you have the P750TM1, how are the temperatures after delidding? Did you do something extra about cooling?

 

I know about the unified heatsink, but I still am going for this over the F5. No point in paying more for older hardware at this point. As with @alaskajoel, my workloads are more CPU than GPU dependent. I will be going for i5-8600K and GTX 1070.

However, the 256W system power limit is new info to me. That's huge if true, and would severely limit the performance tuning potential of this machine. Does someone know more about this?

Edit: As far as the heatsinks are concerned, are they not interchangeable with the ones on the 17" model? They look that way to me.

 

I double checked and I have found the comment, Page 23 of this thread, comment by @Prema

Dang...straight from the horse's mouth too, so it's certainly credible.

Well I guess it's back to the drawing board then. No way I'm gonna put up with the throttling if the EC firmware is limiting the board to just 256W. Imagine if the 190W GTX 1080 is installed, it would limit the CPU and rest of the system to just 65W! You can't even run the CPU stock at the same time, let alone any overclocking. That's just awful!

 

Here is a NotebookCheck review of the X4C (i7-8700K + GTX 1080) which notes the same 256W board power limit under the "Energy Management" section: https://www.notebookcheck.net/Euroc...0-Clevo-P751TM1-G-Laptop-Review.281388.0.html

"Strangely, we cannot record anything higher than about 256 W even when under extreme (Prime95+FurMark) processing load. The system fluctuates between 193 W and 256 W when under extreme loads despite setting the OS and GPU to High Performance mode. We are unsure why the notebook is unable to maintain a stable power consumption when under extreme loads."

This is unacceptable IMO, and makes this notebook a non-starter.

 

Nothing super special. Delidded 8700k with Liquid Ultra and the paperclip mod to increase heatsink clamping pressure.

I really hate to be the voice of disappointment, but how much more are you looking for? When notebookcheck was maxing it out, the GPU was at 90c and the CPU was at 86c. It doesn't really matter if its power limit throttled because there is literally zero thermal headroom at its limits. The notebookcheck review unit is delidded, possibly without an undervolt, so maybe a little bit of gains there.

Frankly, I'm impressed they got that much out of the review unit. If I can get my 8700k + 1070 to hit a thermal limit when stressing both overclocked components (even without resorting to P95+Furmark,) I can only imagine what would happen with a synthetic load like that.

The only somewhat frustrating power related throttling event I have is the current limit throttling when undervolted and pulling 125w during short bursts. I don't find it that big of a deal though because there is no way I could sustain that type of power consumption long term with the thermal situation.

 

What is the paperclip mod?

The NBC review unit wasn't thermally optimized; they never are. No undervolt, and Eurocom uses Kryonaut under the heat spreader when they delid, not liquid metal. A 15-20C drop wouldn't be out of the question with a proper delid and tuning.

The 256W EC limit basically negates any point of having a 8600K/8700K in there if a 1080 is configured, since it'll just throttle down to 65W under GPU load. Might as well get an 8700 then. I've had bad experiences with CPU throttling under CPU+GPU load on Clevos in the past, so I don't want to relive that.

 

This is a dream. There is no radiator left to exhaust the heat. I have liquid metal under my IHS and a 150mv undervolt and it gave me at most 3-4 degrees under sustained load... which were immediately consumed by another 200mhz of 6 core turbo boost. Sure, you might see a 20 degree drop with LM in the short run as it becomes more efficient at warming the heatpipes, but once you reach the point of saturating the radiator, it doesn't matter.

 

Every Clevo since the original DM-Series had these 'power-walls' in place...every Notebook ODM does something along those lines.
Removing them has always been a lot of work, but every model that got a PremaMod has those limits removed and only leaves thermal throttle in place for safety reasons.

 

Is the "unlocked BIOS" option that Eurocom offers for the X4C (P751TM1-G) a Prema Mod?

 

Nope. @Prema don't make mods for Eurocom.

If you don't see it below... http://www.hidevolution.com offer Prema custom Bios. Higly needed!!

https://premamod.com/partner/

 

Worth keeping an eye on the VRM thermal pads and ensuring they always have a perfect fit if you remove the heatsink as they can be under a lot more stress than stock with the above.

 

Does stock Clevo BIOS contain any WLAN whitelist/blacklist?

Reason I ask is that I configured my P750TM1 with the crappo Realtek b/g/n card because I already have a Killer 1525 ready to put in. But the 1525 is not officially offered with this machine.

This makes me wonder, what exactly is the unlocked BIOS that Eurocom is charging $125 for along with a CPU delid that doesn't even use liquid metal?

 

Actually, I have read that Eurocom delids all K-series CPU by default, someone can confirm this?

 

Even if so, I've confirmed that they use Kryonaut, not liquid metal, under the IHS. So it doen't help much.

 

Wait till you try Eurocom's customer service once you get your laptop. you'll be in for a nice surprise

 

The ones I've spoken to seem like pleasant, reasonable people. Do they have an about-face after the point of sale?

 

Sales will be your best friends obviously. I am talking about their tech support/customer service.


The answers I got from them when I had a Eurocom Sky X9 just made my jaw drop in awe. I will discuss the details but you will remember this post when you do have any reason to contact their tech support.

 

Seems like adding one year warranty is throwing the cash in the trash bin, right?

 

Probably. Is it sure? no. maybe I was unlucky. This was 1.5 years ago. Maybe things have improved. You don't want to buy such an expensive laptop without a proper warranty or better yet. Just get it from a Prema Partner and call it a day.

 

I've actually talked to one of their tech support people when I had some technical questions regarding this laptop. Maybe not as well-versed on the nitty-gritty details of this specific model as the enthusiasts in this forum (how many resellers are?), but helpful nonetheless.

 

Well that's good then. I guess I was just unlucky. When are you getting your machine bro?

 

Well, I have not ordered yet as I still have some things to discuss with them.

Read...

 

I have 3 machines from Eurocom. Their education/black Friday/trade-in discounts have been too good to pass up, but that doesn't mean they would be my first pick otherwise.

I've had 4 encounters with their service department and all but 1 left me disappointed. YMMV

 

Google brought me here as I was searching for Sager NP9155 + GTX 1080
I see that on the first specs post the 1080 isnt even listed but I can find configs of 1060/1070/1080 , does this mean that the NP9155 is compatible with all three or not, I'm excited as this will be my first MXM module laptop.
Is there something that prevents upgrading from 1060 to 1080? because I see some mention their 8700K+1080 so I know it can be done but I would like to be 100% I can actually upgrade in the future to 1080 because I come from the school of thought that Laptops are unable to be upgraded (hence my excitement over the $$ in my bank and finally the ability to afford an MXM-module--able laptop)

 

the people that state laptops cannot be upgraded are usually from the same tier that tell you with absolute certainty that NO laptops should EVER be overclocked AT ALL, because nuclear meltdown

Be sure you buy from an @Prema partner shop. Always great have Prema involved in your laptop

Or the BGA Boys Who don’t see the advantage with socketed hardware

 

Yes, I'm in the same situation, there is a 500-600$ difference between eurocom and a prema partner (I compared with all the prema partners).
That's why I am struggling with the choice...
My configuration is i7 8700k (delidded by them if possible, I don't want to lose the warranty ) and a GTX 1070... What exaclty I am missing without the prema bios?
I have read about ram frequency blocked at 2400 Mhz (On P751) and Intel SpeedShift Disabled... What else I will miss?
The possibility to overclock at all?

 

Prema BIOS Benefits;

• Restores user ability to overclock or underclock the CPU
• Restores user control over CPU power settings (voltage, watts, amps) for optimal performance and/or thermal efficiency
• Restores ability to control non-turbo CPU core ratio
• Restores ability to control CPU c-states and p-states
• Restores ability to control BCLK (northbridge) and FCLK (System Agent) frequency
• Restores ability to enable Intel Speed Shift Technology functionality
• Restores ability to disable Intel Software Guard Extensions (SGX) functionality which is intended for software developers who want to use that feature and causes erratic system behavior
• Restores ability to control RSR, Watchdog Timer, ASPM, ACPI sleep and hibernation functionality
• Restores ability to control RAM timings, clock speeds and enables the utilization of XMP profiles
• Restores ability to control selection of Legacy, UEFI and CSM to install whatever operating system is desired
• Restores ability to control CPU-based DEP, AES (encryption) and Virtualization
• Restores ability to control GPU scaling, PCIe speed and power management features
• Restores control over Thunderbolt and USB 3.1 configuration
• Restores control over SATA port configuration and Intel LPM. Having the ability to disable drive ports allows exclusive control over what drive receives the BCD/boot sector, system and recovery partitions during Windows Setup and eliminates the need to physically remove non-OS drives when installing a new OS.
​

 

Wait really? So 3000MHz is a waste of money and doesn't work even when set to XMP-3000 in BIOS? Anything higher than 2400MHz is blocked from running faster?

 

unlikely that its blocked. even if ure unable to use bios settings due to bone stock locked down bios, ull still be able to tune ram settings via intel xtu. although in my case, premamod provides more tuning options for ram than intel xtu offers.

New member here, purchased a Sager np9155 just about a month ago. It’s used for GIS/CAD/Survey work, no gaming. I’ve spent several days in my free time reading through this thread on and off, and I have a couple questions/remarks after making it to the end.

1. This will be a workstation more or less, would I be better off removing the battery since it will be plugged in 99% of the time. I see that it shouldn’t be charging if it’s full, but wanted to ask. I assume I don’t need to make use of the flexicharger settings if it will not continue to charge as is with a full battery.

2. Does Sager ship these delidded? I’ve got an i7-8700k in mine, from what I’m reading a delid is preferred for the “k”. Is this for heavy gaming applications, or just the k series in general?

3. Will a delid help the overall lifespan, and will I notice any gains beyond temps dropping? The longer this machine lasts, the better.

4. The main program I use for mapping (ArcGIS Desktop) works much better on chips with higher single core scores, Will I see any benefit in overclocking any components?

5. Can someone point me to a generic guide for overclocking, if it is something that would benefit me. CPU I somewhat have a handle on what’s going on with the numbers, GPU and RAM, I’m lost.

6. I have the gtx 1060 as I mainly work in 2d spaces and didn’t need to spend up. When taking a look in the ccc, under the gpu oc tool, my card stays at 0 degrees, is something not functioning properly here, or does it only show temps if you overclock it?

Feel free to flame me if these are redundant questions. I’ve spent the better part of a month trying to read through this thread alone on tapatalk when I have spare time. Some of these threads are getting seriously big in page count, I just don’t have the time to tackle them in a timely manner.

Thanks in advance for any helpful answers.

1. If you are doing work keeping the battery in will act as a UPS.
2. No, our parts are shipped to Intel spec.
3. The CPU itself is not usually the part that goes in a machine, lower temperatures do help life on average but it depends.
4. Linear gains with frequency most likely.
5. I would leave it at stock if this is for workstation use.
6. Looks like a quirk in the software.

 

I’m more of an end user than a get inside and know what everything does, so I may have used some wrong terminology, but you answered what I needed. Thank you sir

Not a problem

 

Does anyone know if a 15mm 2.5" HDD will fit inside the Eurocom Sky X4C?

 

Anyone plan on using something like this?

https://www.demcifilter.com/Laptop-Dust-Filters

Dust filters meant specifically for laptops... right now my laptop is surprisingly quiet (still haven't pushed it to the limits) and I'm being anal about keeping my room dust-free, but I travel, so in the future who knows.

I could put these dust filters on the laptop, and whenever I'm running it heavy, I'd put it on a Cooling Pad. I think even with the cooling pad off, it'd get more airflow "cooling-pad+filter" than "wooden-desk+nofilter" right? Is the fan-filter's airflow restriction really significant?

Just being a little paranoid since I've got a friggin 8700k in a laptop, and want this baby to run smooth for years.

Another idea I had was putting dust-filters *on to* the cooling pad itself, so that it would blow only clean air into the laptop.

 

Wouldn't recommend putting it on the laptop itself since any obsctruction of the vents is gonna impact thermals.

For a DIY dust filter on the cooling pad, use women's pantyhose on the bottom.

 

Is there a recommended or preferred cooling pad? I’ve got mine propped up on all four corners with some boundary line ribbon rolls lol.

Ok, will try the pantyhose trick

Btw, I tried connecting via ethernet... no ethernet driver? Should it install with the Intel 9260 wireless chip? (I'm trying to transfer massive amount of files from my old machine).

If you *don't* choose the killer, but the Intel chip, what LAN would you use? The Intel site doesn't seem to have LAN drivers.

ATM trying to download the "Update LAN driver version: 9.0.0.46" from here,
http://www.clevo.com/en/e-services/download/ftpOut.asp?Lmodel=P7xxTM&ltype=9&submit=+GO+

but if the driver LAN chip is Intel, it should be on their site, no?

{update} Just downloaded the LAN driver from the Clevo site. Seems to be Killer LAN. Does that mean if you choose Intel Wifi you've got no ethernet? I don't think so - device manager shows a device with no driver (I did try clicking update from device manager btw).

 

To my knowledge, there is no Intel ethernet LAN option for this machine... only the Killer E2500. My driver installed automatically with the Windows 10 installation. You can confirm in device manager for your ethernet device and the Hardware Ids should include "VEN_1969&DEV_E0B1&CC_0200"

I usually avoid the Killer software and just use the stand-alone driver. I've never been impressed by the QOS features and it shuts off the Windows NDU (Network Data Usage) service for it's own bandwidth monitoring functionality. This intentionally breaks the networking statistics in task manager which I find quite useful.

 

killer / intel chip only refers to wifi. ethernet is not exchangeable and is a killer E2500 on your machine, so killer driver it is
