*** Official Sager NP9175 / Clevo P775TM Owner's Lounge! ***

I just got an EUROCOM Sky X7C with a i9 9900KS delidded and unlocked bios, a RTX 2080, 32GB RAM 3000MHz and 780W AC adapter.

It came with -0.50 undervolt in the CPU and the temps went up to 90ºc or more in Cinebench.
I undervolted to -125 and now the Turbo maintain 4.7-5.0GHz in intensive apps and the the temps are 85ºc aprox.

Is -125 undervolt bad for the laptop for a long time?

 

You should have seen the reaction taking the p570wm I had through the airport. Basically like having two p750 machines in a single unit.

 

Well, that thing did look like a portable nuclear reactor.

 

The P570WM was the coolest though. I remember the good ole drool days. I couldn’t afford one at the time. And I always dreamed of owning one, and putting a Xeon 1680 V1, V2 (8) core inside. The Xeon 1600’s were unlocked until broadwell E V4’s. Or just running the 3960 or 3970X which is still decent to this day

 

The less voltage the better! My default bios has a -100 undervolt. But with stock speeds my 8086K will run with a -225 undervolt just fine.

also, just because you are running -125 undervolt. Doesn’t mean the next guy can. Even though that is not a massive undervolt. Just an example. There is a lot of variances in these motherboards and processors.

Reduce voltage as much as possible. As long as the system is stable of course. R15 is a decent stability test. But if your temps are 85-90C in R15 then any heavy AVX load would push temps to 100C easily. Especially BFV.

The 9900KS is pretty much a better binned 9900K. Undervolt this chip as much as you possibly can. I’d slowly reduce -0.010 at a time then confirm stability. It’ll eventually BSOD then you’ve found the limit.

Oh and nice laptop. These laptops are extremely resilient to abuse from heat and overclocking. I BSOD mine daily just for fun.

 

I tried -140 undervolt but windows BSOD.

I will stay in -125 undervolt, all the games and emulators, especially the PS3 emulator that uses AVX, don't reach 90ºc and i have the fans in custom mode but very low and quiet.
In summer i'll have to up the fans speed.

The Eurocom bios has so many parameters that for sure i could optimize more but it's fine for now.

 

You need to undervolt the RTX2080. It works miracles on the CPU and GPU temps during a gaming load. Youll probably knock 10-12C off the GPU alone. And maybe 3-5c off the CPU

Try Battlefield V too. It is more intense than any stress test I’ve got lol. It’ll push temps to maximum levels. If it runs that game for 1 hour then the system is stable for sure 100%.

 

The biggest trick was the CPU power and that has been out classed by the 9900k now though.

 

It's a binned "binned" chip at this point, lol

 

For sure. But if one still had a P570WM I’d be looking in to running a Xeon 1680 on the cheap. It still makes for a extremely powerful laptop.

 

The problem is obtaining spare parts. One of the reasons bro @Mr. Fox sold his.

 

Man this is a fast laptop.

 

FInally had time to install the 9900KS. Had to do a CMOS reset but after that BIOS recognized it. Unfortunately the factory set 5.0 Ghz (all cores) is just too much for this chassis so I had to downclock and reduce voltage. The lowest voltage I was able to get to is 1.070V during all core load or 4.6 Ghz!
WOW!
My 9900K would BSOD with this voltage even on 4.3 Ghz.
For me 4.6 Ghz is way enough, it still easily beats even a 5.0 Ghz overclocked 8700K/8086K.

After playing 2 hours of Rise of the Tomb Raider (this game is very sensitive for CPU voltage, if its not stable the game or the entire laptop crashes within a hour) I run some Cinebench and FireStrike runs.
Please note that that the fans were on max however tests were made after the inside of the laptop was warmed up due to gaming. (if I run these tests right after boot the temps are about 3C lower).

Cinebench R15
After 1st run:


during 6th run:


Fire Strtike run:



No throttling at all which I find cool considering that I only use the stock pew pew Clevo BIOS and only the single stock 330W adapter.
I consider these temps acceptable considering that the CPU is using the stock IHS with STIM, if I were to delid it and install the copper IHS I have for 9th gen CPU, I could reduce the temp by another 5-8C.

I do not have my results when I tested the 9900K but I can confirm that the 9900KS is a binned, much better quality chip which can work with lower voltage and thus give lower temps. With same all core 4.6 Ghz setting the stock 9900KS is about 10C cooler than my delidded 9900K (and about 16C cooler than a stock 9900K). With these settings this 9900KS runs around the same temp as my delidded 8700K did, however gives way much higher performance.

tl;dr: If anyone wants to use a 9900 CPU in this chassis then among all of the variants (9900, 9900K, 9900KF, 9900KS), only go with the KS! This chassis can not handle its default settings however after downclocking and setting low voltage it can still give much higher performance than any other BGA laptop with acceptable temps.

ps: Darn, just realized that RAMs were running on 2666 mhz instead of XMP 3000 mhz :/

 

A machine a 1/3rd of the weight can keep up. I'd say it's a moderately powerful machine in the grand scheme of performance machines.

 

Yea your right. The ole P570 is a Dinosaur now. X79 is old news ever since Ryzen increased our mainstream Processors core count.

 

Now imagine giving that puppy a delid and a lapping

 

Pretty much, a fun one sure.

 

I’m starting to question if my current CPU actually is delidded. I feel like my temps should be better. Plus the black sealant around the IHS lid is pretty clean looking. Almost too clean looking.

I may have to remove it and confirm.

I can only run 4.8Ghz in BFV. And temps are in the low 90’s. I know the game is stressful. But still. If I run 5Ghz it will eventually throttle to 4.9Ghz and stick at 4.9Ghz with temps bouncing off 94-96C on some cores.

“Previous owners said that he was told it was delidded” so I’m uncertain.

 

I remember the good days when I first got in to X79 platform. I was pushing a i7 3820 to like right at 5Ghz or 4.95Ghz. The multiplier would only allow x44 hard limit on all cores, and I had to bump the BCLK for the additional overclock. Sandy Bridge would overclock pretty good though

 

My chip was not the best, 4.3-4.4 was where I ran my 4930k.

 

So I witnessed some strange behavior from my GPU. When playing Witcher 3 (everything high/ultra, 1080p) my temps are normally around 65°C with a conservative Afterburner undervolt and max fans. Since the past week after an hour of gaming or so with stable temperatures, suddenly my temperature ramps up really quickly, 1 degree per second, until it hits 86°C or more. Instead of throttling the gpu keeps its clock, then crashes the game. Before I was able to 'fix' this erratic behavior by reverting Afterburner to standard voltage settings, restarting, then reapplying my undervolt. Now this no longer appears to work. If I don't apply the undervolt, or underclock the card, the same thing happens. Any ideas?

 

Follow temps, power consumption and fan speed. This for both the Cpu and Gpu. Aka follow what is about to change.

 

Do you have liquid metal applied on the GPU die?

 

Good evening

First of all I'm sorry but my English not so perfect but I will try do my best explaining whats going on .

I have few issues with my Clevo P775TM1 ( PC Specailist Octane VI. )

I got my brand new clevo ( i7 9700 ( non k ) , 2x8GB RAM , 250GB Samsung SSD , 1TB Samsung SSD , rtx 2080 , Full HD 144hz G-sync panel ) few days ago . Out of the box strait away I have noticed something not right .... under stress test ( aida64 ) core temperatures were strangely very low ! Later I have noticed when I put the cpu under stress the cpu ( all core , see picture1 ) down clock itself .


I seen Package power ( Turbo boost power limit ) only 11W witch is post to be least 65W ! Took me few hours figure it out what is wrong ! First I thought maybe the power adaptor or electric socket ... I was wrong . I did install xtu for looking around what a heck going on and that is what I have found :

CPU core icc max ( default setting ) only 10A !!! T and U type Intel CPUs runs on 66A icc core max so this 10A for desktop grade CPU far too low !


I have changed that to 130A + 85W turbo boost power limit and everything works fine .




Other problem more serious because I can't find anything for fix it !

I have no G-sync option in nVidia control panel ! rtx 2080 ( driver 441.41 ) + Full HD 144hz g-sync panel . Device manager only one display adaptor ( rtx2080 ) so optimus not an issue .


I'm not sure what exactly is the source of those problems but I have a wild ques , both problems point to the motherboard . EC malfunction , BIOS . Also find few articles about i7 9700 ( non k ) has issues with G-sync support .

BIOS version : 1.07.27 ( updated from 1.07.25TPCS3 )
KBC/EC firmware : 1.07.13

Any suggestions more than welcome .

Thank you

 

At first sight I don't see anything abnormal. Fan speed is at constant max fans, power consumption is relatively stable. CPU is downclocked to a steady 3.7ghz when playing Witcher3 (doesn't need more) with a 60fps cap in RTSS. I'll do some more tests on Monday.

Yes... but if there was something wrong with the LM I would see temps rising immediately, or not?

 

Call support. Test also with older Nvidia drivers. No Optimus on Clevo LGA models.

Your pictures is broken. Sign up and use Imgur host.

Yeah, do more tests. You yourself said the temps increased fast.

 

Liquid metal will diffuse into copper over time, so temperatures might have been fine initially but degrade over time. I'd check the application and reapply if necessary.

 

Plus if the LM dries in a small area you can get hot spots on the die the temp readings will not report.

 

Hi

I have issues with audio drivers from windows 10 update. It seems the audio is always blocked at maximum volume , despite controlling its level . Each time it updates audio drivers automatically.
So I disable windows update and installed audio drivers from clevo site , it works here ,as I can change volume I want , but I cannot open audio realtek manager or sound blaster connect.
Any fix ?

 

What about the drivers from your reseller or the latest from the realtek site?

 

I found that you need to install the 'clevo' realtek driver whilst not being plugged to the internet. After that you can allow updates, the store will automatically install the realtek app and SB connect 2 app correctly.

 

Can someone please help me?
What does CPU VR CUSTOM Setting in bios mean? If I enable it default value is 0. I asked it cause when i try to go 4.8 Ghz with ThrottleStop VR CURRENT give error and blinking.
Thank you for your help.

 

This is what happens when I don't apply my undervolt or fps cap. Max fans. (Normally the game freezes at >85, but I stopped waiting at 90°C for obvious reasons)



It does look like the LM doesn't hold anymore. Up until now this probably remained hidden by my undervolt + fps cap. If I reapply my undervolt with a low cap of 40 fps, temperatures remain acceptable (around 60°C). Of course, these are not the fps I signed up for...

Does re-applying LM paste fall under the warranty? Or does this depend on the reseller? Not looking forward to do it myself...

 

That's your CPU current limit in amps, p775tm1 default should be "600" or 150A
In Intel XTU its "Processor Core IccMax"

I'd reach out to your reseller and get a definite answer. IMO if resellers offer LM options for laptops, they need to have the copper nickel plated or take proper steps to ensure that copper is properly soaked.

 

Do you think it would help if I increase this value with my “vr current” problem?

 

You mean set it to the default "600"? Yes, your CPU is only going to pull the current it needs.

 

I didn’t understand. “CPU Vr custom setting” in bios is set to disable. If I enable it shows “0”.

 

Still default before you change anything. 0=Default.

 

So I should increase this value to 600, right?

 

I got it thank you.

 

600/4=150A. Delete TS ini file and you’ll see the true numbers once you reboot and launch TS again.

 

Ok I’ll try, thanks again.

 

There are usually tool tips on the bios option it's worth reading.

 

Thanks for your reminder

 

No problem, they can help avoid setting something to a silly value.

 

I run mine on 1023 VR limit. Which is the maximum allowed. My cpu will pull what it needs when it needs it. Running a overclock at 4.8Ghz to 5.0Ghz on my 8086K results in the default VR value power throttling my CPU under heavy load. So I just run 1023.

 

How are VRM temps looking after prolonged use? Btw, 1023 is 255A, I believe @Prema mentioned 600 is HW limit for the p7xx and 720 for the p8xx.

 

Yea 1023 it is 255A in XTU. Mine doesn’t default to 600 though in the bios at all. So default setting will power throttle for some reason. I am unsure on the VRM temps. I’ve kinda gotten to the point where I just use it for long long gaming sessions. Such a reliable machine it has been.

I will run BFV tonight when I get home anyways, and I’ll see what the VRM’s run up to.

Also just curious is 0.925V at 1,898-1,911Mhz good for a GTX1080? What could you get with yours?

 

I think my 1080 ran 1936MHz at 0.950mV in the p775tm1

 

Like 4 volts to the CPU.
