*** Official Clevo P870KM1/P870KM1-G/Sager NP9876 Owner's Lounge! - Phoenix 3.0 ***

Very droll.

 

would be a nice idea, but i'd pass on it for this model because theres just no more room for this laptop. a simple 4 fan design machine would be a saving grace but clevo just had to cramp two 1080N into it and share the heat towards CPU side of cooling, two fans for two GPU, two fans for CPU would have solved all issue with modding, issue is not enough surface area for cooling.

 

Already did that with an Alienware

 

Anyone know what temps I should expect on my CPU? I got the 7700k and dual 1080s

 

It depends on the load on everything. What are you seeing?

 

Don't know yet I'll have the laptop tomorrow.

 

i want to buy it so bad but 1) no money, 2) waiting for the next gen of GPUs.

 

I'm just waiting on Prema to finally release that BIOS...but loving the system so far, very similar to my SKY X9E, except when the fans go full tilt. it sounds like a vacuum cleaner. Inpressed with the job EVOC did with the computer. Temps and all.

 

louder than dm1?

 

Dm1 isn't loud.

 

True, DM1 doesn't seem loud at all. It seems very reasonable in comparison.

 

Hey guys just got my new laptop in today it has the two 1080s and 7700k

Temps look good at load and idle but for some reason during idle the GPU fans just stay running at 40% and its very annoying. Anyone have any ideas?

EDIT: i set the fan speed offset for the gpus to 0% and now they are reasonable. Temps seem to be fine at idle with the 0% offset

 

Sounds good

 

Is there thunderbolt port driver for this machine?

 

Check the Obsidian driver updater. I remember seeing one in there

 

Does anyone here have the normal P870KM (single GTX 1070 version from HIDevolution) with the vapor chamber upgrade? I am curious to see whether or not the CPU runs cooler on this specific model, compared to the dual GTX 1080 model. I imagine there would be less heat being carried over the CPU, from the second GPU's VC area. I am looking to get that exact model with the VC upgrade, and I am mostly concerned for thermals, since this thread seems to be posting very hit or miss QC on these specific Clevo models.

I am not exactly looking for the best performance, as longevity is my number one goal. A cool running GPU and CPU (sub 70C gaming) is what I am striving for, and if I have to undervolt/underclock to achieve it, I am prepared to do so. I just don't want to invest $2300 into a laptop that's heatsink won't be up to par to accomplish that goal.

 

The p870km1 is substantially louder than my p870dmg. I dont care for fan noise but if you are one of those people who hates fan noise I cant see how you would get around this. Pretty darn loud. Even a auto fans while gaming demanding games fans get loud.

 

Go to device manager and disable L/R eardrums

 

I have had mine running all week and yet to see above 70. Played Elite Dangerous, Ark, and Rocket League in that time. And that's a single 1080 system, a single 1070 would probably be a bit cooler.

 

Is that with the vapor chamber? What is your CPU clocked at? I plan on slightly undervolting the 1070 with Afterburners voltage curve, so as long as the VC is as good as people say it is, I don't think I'll have any problems on the GPU side of things. I am mostly worried about the CPU at this point.

 

Vapor chamber yes. Haven't touched voltage yet, waiting for Prema BIOS before I tweak the CPU

 

There is less heat going over with a single card and the newer heatsink with a single pipe too. It's not going to be cool running when pushed beyond 4.5Ghz though as you are running around a Ghz faster than most other notebooks at that point.

 

Is this in response to my inquiries on the VC and single 1070? I actually did not intend to overclock the CPU. If anything, I was going to go in the opposite direction with an undervolt/underclock. I know this will likely annoy people, as when I bring this up on other forums, the general responses are: "Why buy an unlocked CPU and an expensive socketable laptop just to underclock it instead?!". My answer is always the same. I care about longevity, not about performance. I want a socketable CPU, in case it dies in the future. It's easily replaced. I want lower thermals, to stave off that potential death for as long as possible. I use a stock 4.2ghz 6700k on my ITX PC, and it does just fine for 1440p gaming with my desktop 1070. If I can get a laptop that does the same, with similar thermals, I'll be more than satisfied.

In your honest opinion, does the VC heatsink make a substantial difference in thermals, to warrant the cost? I know it would be difficult to ask "how much lower will my temps be by X degrees Celsius", but I simply want to know if the difference is indeed noticeable for a single card solution. It's a pretty significant cost if it's only going to be a few C difference at best.

 

Do you have a pic comparing the new VC and old VC? I have the bridge with 2-pipe.


@bloodhawk




Also, I removed the baffle on the front grills, does this affect anything?

 

If you get it from HID or OBSIDIAN with single 1080N and 7700K with the vapor chamber, you will not have to worry about thermals with a solid 4.4-4.7GHz CPU speed and a stock GPU. Just... at all. The most you may need is max fanspeeds at some point but I would expect never hitting 80c on any part to be an easily achievable thing with such a configuration.

I recommend against the 1070N not because of what a 1070 should be capable of doing, but because with the pitiful ~115W limit on 1070N cards, it will never achieve its potential. The 1080N does not have this issue and can boost consistently above 1848MHz pretty much 24/7 in this machine.

This is if you can afford it, that is

Just checked, my other VC is 2 pipe, not sure which one is in the DM3, since that isnt back from HIDE yet.
btw. i have these thicknesses - 2 mm x 2 , 3mm x 1, 1.5 mm x 1. (The Chinese pads)

 

Hmm, according go prema the 1 pipe is newer.


Possible different thickness between 2 pipe bridge and 1 pipe bridge version of VC?

 

Doubt it. Clevo doesnt have brains enough for that. They will take the shortest and cheapest route.

 

Ok

What kind of blood sacrifice do you want for the 1.5mm?

 

Oh hey, I've seen you on the LTT forums as well. Nice to see you here. As for the 1070, is this every 1070? I've seen some mobile 1070's on 3dmark clock at 2000+. I am still new to the world of MXM's, so I don't know all of the different variants that exist (along with their specific power limits). Do you happen to know of any places to read up on the various power limits of the Pascal mobile cards?

As long as the mobile 1070 is comparable to the desktop version, I won't have a problem. Especially since G-Sync will aid in that department as long as I remain within it's refresh window (easily done, given the 1440p resolution). The only way I can afford the 1080, is if I completely forego the VC, and I just don't see myself choosing a marginal boost in performance (20-30%) for worse thermals. Again, longevity > everything else to me. Basically, my budget is $2500, and it seems the P870KM is the only laptop that checks every box on my list of requirements:

120hz, G-Sync, and good thermals (along with socketable hardware).

 

I have the VC with a single 1080. But if I had to choose between VC + 1070 or Normal HS + 1080 I'd still go the 1080 route.

 

Does anyone have any pictures of the stock CPU heatsink, vs what the CPU heatsink looks like when the VC is installed? I am mostly concerned with CPU cooling at this point.

 

At 5:20 his idle is around 27 deg Celsius. OC to 4.9 is 30 deg Celsius.

 

The 7700K in this test run as Throttling Hell in Cinebench R15. Both with stock and oc'd to 4.9GHz. 923cb in Cinebench R15 with 4.9GHz is awful and a lot lower than you should expect(+-1080cb). Horrible optimization by the reviewer and awful thermals as stock. And the same terrible result for 4.2GHz

I tested 2 non optimized runs today with 4.2GHz and got 935cb as minimum and 940cb as maximum for [email protected]

The test from the review... 4.2 and 4.9GHz Throttle Hell!!


Older test with lower clocked [email protected]


[email protected] tested today. 935 as minimum and 940cb as max




Older test with same 4.2GHz clockspeed.

 

Anyone have any ideas as to why my fan speeds are so high while gaming? My temps are sitting around 70 to 80c but the fans are just always going crazy. I had the same laptop and fans weren't too loud but I had to exchange the laptop and now it's just so loud.

 

All 1070N cards are TDP limited. You can't get around it without a custom vBIOS and those are nonexistent right now. Only one person seems to be sure it can be made and as far as I know it isn't ready yet. 115W with spikes to about 120W are what you'll get for a 1070N and it isn't enough to hold all the boosts. It'll be power limited, especially quicker at higher resolutions.

I would honestly take the 1080N still even if you couldn't get the VC, but remember you have a little discount for being a NBR member from HIDevolution . Maybe do as much penny pinching as possible, and ask about the NBR discount? You could always purchase the VC setup later too.

 

put liquid metal from the resistor

 

Wanna try it and report back?

Yes the power mod gets around some protection but not all. You then become voltage limited pretty quickly.

 

Did you just paint the LM on top of the R005 resistor?

I know that mobile counterparts have less max voltage than desktop.

 

Go for the 7700 rather than the K then

The vapor chamber is great for video card temperatures and slightly hurts CPU temperatures.

There are several shunt resistors around the PCB that need to be painted.

 

Or do this next to the power control IC - (bye bye to warranty)

(This is on the Desktop 1080Ti, will be similar for the 1080's, but one will need to find the respective caps to solder the 10Ohm resistors on top of)

 

All of these physical mods are bye bye warranty

 

Pretty much. What people dont understand is that using LM, does not result in the most stable or measured amount of Resistance/respective current.

 

It's ok for a slight tweak that the mobile cards need to generally.

 

Hey im having one small issue. When I'm playing any game my fan speeds are crazy high and they usually get to almost max fan speed on automatic mode. My temps are perfectly fine tho. CPU and gpu temps are around 80C. Is there anything i can do to adjust them? Even after i shut a game off my fan speeds are around 50% for no reason at all.

 

Probably because the temps are not as low as they were before running the game. Give it a little time to dissipate the thermal build up. However at 80C , the fans better be running at 100%.

 

even after the cpu/gpu are back at operating temps the fans are still running too loud for some reason thats what annoys me
