Yes I am talking about the power plan settings. I was looking at my logs and realized that for example 6 hours of idle my CPU ran at 4.5 GHz the entire time. So normally when I wake up in the morning after my computer idles all night the CPU temp drops to around 38c. Last night I adjusted the CPU minimum to 10% when plugged in and this morning my CPU temp was around 32c. Personally I do not care about power consumption or anything like that but I do want longevity. My only question would be is it better or worse to have the CPU always dropping and rising or would it just be better 100% 24/7 for longevity.

For benchmarking use the High Performance 100%/100%, for normal day to day use the Balanced Power Plan with 0%/100% is best - it keeps the CPU cool by dropping clock when it's not needed, like at idle or in between intense gaming loads. There is no "wearing" when upclocking / downclocking, so long term it's advantage is the lower temps.

Architecture changes compared to Skylake
"Faster clock speed changes (improved Speed Shift technology): it takes less time for the CPU to transition from one frequency to another, e.g. from a low-power state to a high-performance state - consequently this may bring an increase in performance and responsiveness"

 

Also power savings, by speeding up faster you can go back to idle faster.

 

My idle clocks speeds are at 25%, on my desktop and the laptops. Never had any issues with the responsiveness.

 

You'll have a longer battery life so you might actually have time to get that work done rather than just quickly browsing reddit that one time.

That could be a downside of lower idle clocks

 

Hello Experts,
I have a question about the p870km1.
When I would buy it for Gaming and Work , is there a possibility to downclock the gpu for work?
Because here is no optimus available right?
At work i dont need graphic power but a more quiet laptop.
Thank you for the help.
Br,
Hendrik

Still on re-paste 2.1 with Grizzly Conductonaut on CPU and GPU's with dried up old thermal pads. 17w/mk pads are on their way. 15+ Hours of 7860x1440p gaming, browsing and some Prime95 small FFT tests with fans set to "Overclock" only. Also 4th 1080P accessories screen enabled. This is really pushing the P870KM1-G. Please see bottom right hand corner of HWiNFO64 program on the top centre accessories screen for total uptime (15+ Hours). Photo attached below or view forum image:

BIOS: Stock Clevo Bios
Ambient temperature: 20c-24c through out the full day.
CPU Max Temp (4.5Ghz 7700K): 82c

"Maximum" fans on Clevo control centre has never been used on this test below the 15 hour mark, same with a laptop cooler. This is strictly on "overclock" fan setting using Clevo control centre. Though please note: I did put the fans on full on the last 5 minutes just before the screenshot, to see how low my base temps would be with full fans. This upload is for other users reference. I hope this helps.

 

Not to shabby lol. What game were you playing? I'm about to repaste mine soon before I go to Afghanistan

Mafia 2, Mirrors edge: catalyst, and Max Payne 2. The temps really get high when I'm playing at 7680x1440. When I play on my laptop 1080P screen its much more cooler though. You need to re-paste! Afghanistan is hot but not hotter than Yemen. I seen broken eggs fry on the floor in Aden city lol.

 

1080p wont load the GPU fully really so i'm not surprised you see 3x 1440p causing more work

 

Hey, I have a P870KM1 and I use it for work and play. At the office its mostly quiet, the few times it went loud was when I decided to run benchmarks and play games. But office applications don't trigger the loud fans. What do you plan to do with the machine at work? What type of programs are you planning to use? I personally haven't had to downclock the GPU for noise reasons at work. Hope that helps

 

It depends on what your doing really, I can game for the most part and the fans don't spin up, but if your rending 3d art or something it might. Internet and documents shouldn't do anything

Thank you for your help.
I watched the video from ownordisown and he recommended MaxFans for gaming so I wasn't sure if the sound will be ok for the office.
Its only programming and some low stuff there.
So you have a low power profile and downclock the gpu?
Thx in advance.

I actually leave it in a max power profile while I'm at work. As long as you aren't doing rendering, and assuming you got a good paste job in there. Watching videos, programming, office applications, will never set off the fans and in essence remain quiet. The only problem, is if you get the 780 watt power supply, those fans are on, all the time. So there is a bit of noise. If you're sticking to the dual power supplies, noise shouldn't be a problem, in an open office.

 

sorry didn't realize the cpu max usage wasn't close to 100%... i guess i just figured it was ;-)
ts is a good tool, you should definately use it (maxes it easy to switch between different cpu perf. profiles and the tweaking options are super!

 

Hello all! Please have a look at attached photo. Is it normal that P870KM1-G's back cover occludes the fan for slave GTX 1080? Or is this a wrong back cover?

 

Yes that is the correct stock plate from Clevo. As the discussion on if it should be that way well that wakes up the hornets nest.

 

I removed the metal cover but I also repasted with liquid metal at the same time so I don't know if the cover made a difference

I am considering selling my Gaming Evoc Rig because I have just moved to a new house and bought a desktop gaming rig and rarely use the laptop anymore. It is few months old and decked out. I am wondering what is the best section to promote it? P870KM1

 

You need 100 posts before you can post in the for sale section. Also, I'm currently selling my KM1, don't need no competition! Lol

Sent from my SM-G950U using Tapatalk

 

It does to the GPU temps yes.

 

Quite curious, does it make a huge difference if you remove the panels? Besides getting more dust and so on into the laptop Would you recommend doing it?

 

Yees, And Yoo will find more info about it, with a search in the forum. Buy a U3 and mod it with better fans + filters who can stop the dust.

 

cheers mate, exactly what I needed

 

Remember you can remove the fans without the metal heatsink itself so cleaning should not be too much of a pain.

 

Hi everyone! Hope you are having a lovely weekend. (not sure if its the right thread)

Seems like an error had popped up while i was playing a game for about 10 mins.

Stop Code: Driver_irql_not_less_or_equal
what failed: Synth.sys

It has reach the 100% restart phase but has not restarted just, just stuck at the error screen. Is it fine for me to force my computer off?

Any idea how to resolve this and perhaps prevent it from occurring again?

@Mr. Fox @Phoenix @Papusan

cheers

 

Sounds like an error from the synaptics touchpad driver. Force shutdown and start your taptop again then when you are in Windows go to control panel/programs and features and tell ne the version if the synaptics driver that you have.

I also suggest decreasing your undervolt by +20 mv so if you had like -80mv before try -60mv now

 

Synaptics Pointing Device Driver: 19.3.4.72
Synaptics BF FP Reader: 5.5.2700.73

@Phoenix I haven't had a chance to dabble with undervolting and what not. Can you direct me to where which program would be best for this?

cheers

 

It's not a program, it's in your BIOS.

I don't know exactly where to guide you since I don't have a Clevo laptop but it should be somewhere in the CPU Performance or Overclocking Menu > Processor

Then change the core voltage offset from whatever it was minus 20, so let's say it was 60, just highlight the field and manually type 40

The Core Voltage Offset should remain a - negative sign meaning, it's an undervolt........ + is an overvolt

also look in the submenus if there was a RING submenu, you wanna put the same undervolt for the ring as well (ring is the CPU Cache)

For more guidance from people who own your same laptop, it's best to ask here on how to undervolt or change your undervolt I'm sure a few can even share some screenshots with you:
Clevo Overclocker's Lounge

Also, it seems like Windows update has updated your touchpad driver as the version on Clevo's site according to your laptop is 19.3.4.66 = http://www.clevo.com/en/e-services/download/ftpOut.asp?Lmodel=P87xKMx&ltype=9&submit=+GO+

So download it from there, then uninstall the current one and reboot

then install the official one from Clevo and reboot again as that error message you posted is a Synaptics Driver Error

 

The menu is in the BIOS, advanced then processor menu.

 

THE ULTIMATE P870KM1-G THERMAL PREP WORK
Thermal pad collection consisting of 17W/mk 0.5mm & 1mm AlphaCool thermal pads, and Phobya 5W/mk 2mm & 3mm thermal pads. Please ignore the cheap stuff on the right...


AlphaCool NVME SSD heatsink using AlphaCool 17W/mk 0.5mm & 1mm thermal pads.


GPU heatsink cleaning and lapping for effective thermal pad transfer and GPU die to heatsink.

 

Just found out that the silver .925 lid has shrunk through the casting procedure. This photo show the BitsPower lid against the .925 silver lid. BIG difference. I'm going to change that soon... (Sorry some bad photo quality due to a close shot, and that's dirt on the silver lid too. I had prep hands )


.925 Silver lid in place with 0.5mm copper shims to hold it down due to the shrinking.


CPU foam barrier in place with Thermal Grizzly conductonaut.

 

Just a note to people looking at the above and lapping the GPU heatsink, be aware that it's a vapor chamber and not a solid piece of copper, be very careful with it.

 

AlphaCool 17w 0.5mm thermal pad for the GPU heatsink and where the CPU heatsink both meet.

A 2c difference on max CPU load. It's now 80c compared to my previous max 82c. On "full" fans the idle CPU minimum temp is now 39c compared to the previous 40c. Please note: this is a minimum CPU temp after a full stress test, not the minimum temperature on first boot. So in theory, the custom made .925 silver lid made a 1c difference. The result below: Using 1+ hour of Prime95 and 1 hour of gaming on Battlefield: Hardline on 7680x1440 Nvidia Surround. This is really pushing the P870km1.
Please see HWiNFO64 for the reference of 4.5+ hours uptime.

Using prime95:
First, I tried "full" fans on Clevo dash with U3+ (x3) Varder fan mod on full. This got me 74c on the CPU.
Then I used just "full" fans on the Clevo dash without the U3+ (x3) Varder fan mod. This got me to 77c tops.
I then finally used "Overclock" fan settings on the Clevo dash with no fan mod, and I got a maximum CPU temp of 80c.
I have tried everything to put the CPU to a full load. It seems to only go 90W.

BIOS: Stock Clevo Bios
Ambient temperature: 22c-24c through out the full day.
CPU Max Temp (4.5Ghz 7700K): 80c

The screen shot below has been finished of with "full" fans on Clevo Dash to show the minimum base idle temps.

 

When you say your minimum temp is 40, you talking about cold temp, like a first turn on of the day or minimum from your stress testing?

Sent from my XT1585 using Tapatalk

 

This is minimum from after stress testing. When I first boot-up; I sometimes get 28c-33c minimum. Please see my other old screenshots bro

 

Yoo say you run 45x, but I can see only for one core. Why not put all cores 45x? As you already have dialed in voltage for 45x.


Edit. Forget to say nice lid

 

That's weird. Is my system missing something that I don't know about. I understand that I drop to 800Mhz because I have the stock Clevo Bios. My CPU ratio is all on x45 and my cache ratio is on x40. Is this right bro?

My max CPU frequency on all cores touch 4.5Ghz too, does this have something to do with my settings?

Edit: I don't know why my first core never drops to 800Mhz hardly too...

 

Yoo should see all cores run 45x in CINEBENCH_R15 (ring/Cashe is 3 bin lower than core clock). But I’m not familiar with stock Clevo bios. Run max performance in Windows power plan.
Edit. Default clocks is 45x for 1 core. 4 cores is 44x

 

Okay thank you. I will download that tomorrow. Also I am on max performance on my windows power plan and Nvidia control panel settings. Anymore tips you can give me please. This stock Clevo BIOS is horrid.

And thanks for the rep. But what is this 7820hk going over 5Ghz. Is this for real?
I never checked BGA before. This has tickled my fancy

 

For stock ratios 45x is single core only so you won't see it all that often. It's not much of a difference though 44x compared to other turbo ranges of lower cpus.

 

No! this 7820hk BGA 5ghz is rubbish, sorry bruv. It can't be. I can not see it. I must be missing something....
Someone needs to fill me in please.

 

It’s BGA Scam!! Read the whole thread.

 

Sorry I didn't have the time then, I was cooking. I have just read it and I have researched on the net about the 7820HK. I gave him 2 reps for making me chuckle lol. I swear they make BGA because of people like these fools. Oh my days

 

P870KM1-G Gameplay temps and results for the .925 silver IHS lid and 17w/mk thermal pads on both. "Auto" fans and U3+ (3×) vardar fan mod with all fans set to 40%. More quieter that way. AlphaCool 17w thermal pads really work super.

 

Not bad, I don't have battlefield what were your temps on BF before the .925? BTW need to work on those gunning skills lol jk

tell me that ngreedia is not downgrading gc performance with drivers. Or mby im wrong, why graphic score is so low?

https://www.3dmark.com/compare/fs/11884708/fs/13719494#

 

My scores are about the same as my older scores. It could be a lot of things, dust or hair in your fans, ambient temperature differences various setting differences between the 2 tests. Your clock speed is lower on the recent test but with out more information it's hard to say.
