Clevo P870KM1 overclocking suggestions w/ i7 7700K and SLI 1080's

Hello all,

So with the recent purchase of my P870KM1 from HIDevolution, I'm looking for some advice on how to overclock and undervolt this sucker until the official Prema BIOS come out. Since I'm not too familiar with the laptop scene, I am wondering what software is the best to use for GPU and CPU overclocking as well as the proper numbers for a 4.7GHz overclock for the CPU in terms of voltage.

I have downloaded MSI Afterburner and have used this software over the years to overclock my GPUs no problem but it seems I can't undervolt them either with the software. Also, CCC has GPU overclocking capabilities but they are rather clunky but seem usable. I tried using Throttlestop to overclock my CPU but my settings don't seem to stick over 4.5GHz and I'm not sure of the proper settings of what I need to use either.

Any guidance would be greatly appreciated on the matter as I'm looking for stable and constant numbers that most others get with decent temps! I'm not looking for anything insane but mostly cookie cutter that gives a little more "oomph" while still stable and cool!

 

MSI Afterburner and Intel XTU are probably going to be the standard programs for overclocking, though Throttlestop is a good one as well.

With all processors, they really aren't guaranteed to get to a certain point. They are all different on how well they can overclock though. So 4.5 might be just the max that your specific processor can get. Would still be worth trying another program to see if it helps, but there is just some luck involved in that on how well the processor is made. Two chips back to back off of the assembly line could have different OC'ing abilities.

 

Oh yeah I'm aware of that. I OC'd my 2600k to like 4.5GHz with no problems on my old desktop build. I was just inquiring about numbers for the i7 7700K and due to the being a laptop, I just wanted to get good clock number to work with and how much to undervolt.

I was at 4.7GHz yesterday with no issues but I'm not sure what to set the voltage at as I've never worked with the software, only BIOS overclocking. I tried settings voltage offsets in Intel XTU but they wouldn't save for some reason. Then again, I really have no idea what to set the numbers at for half of those sliders.

 

You can undervolt the CPU with the stock BIOS. I use a -80mv. -100mv was unstable for me already. But you have to check it for your CPU. I would say start from -80mv and go down 10 notches every time, like -90, -100 etc. until its no longer stable with stress tests.

Edit: You can also start from higher number and then go up if you like. Some guys do that - start from -150mv and then go up like -130, -110 and so on until it is stable on stress tests, i.e. no crashes or hangs.

This was the answer I was looking! Just to find a baseline on where to start and what to use to do it! I did see some information on the BIOS but I didn't want to mess with it since it wasn't the Prema BIOS; glad I can do something with stock.

Do you overclock it at all or just leave it at base 4.2GHz clock with turbo to 4.5GHz?

 

I haven't overclocked it. Heck I even have SLI disabled at the moment. I feel the i7 7700k and one GTX 1080 is already an overkill for all the games I played so far.

Regarding undervolt, read my previous updated post. You can also start from a higher number like -150 and then add voltage until its stable.

Older Clevo models had some bug in the BIOS where the voltage offset had no negative option. Hence the need for a Prema BIOS for undervolting. This is no longer a problem in our laptops as it is fixed. Prema BIOS still has a lot of other advantages though for tweaking. Luckily I bought my laptop here in the EU from Obsidian-PC who also offer their own unlocked BIOS so I can tweak everything

Edit: Damn autocorrect. Not overcooked, I meant overclocked.

If you don't know much about these, just ask @Phoenix to help you. Since you bought an EVOC machine, he will help you out to setup and tweak everything via TeamViewer

Yeah I definitely need to get with @Phoenix so he can help me with everything! I've done a couple things but not nearly enough with what he does as a whole!

Hello Guys, any one can send me your overclock setings? i have an Sky X9E3 , I7 7700K delided S/GTX 1080.

 

Wow i have bought a EVOC P870DM before, did he have any tweak for me? , i5 6600K and GTX 980 no M . I also bought BIOS from Prema

 

Do NOT use XTU on clevo laptops

 

What is the issue with XTU in clevo laptops?

 

It ****s up the fan table.

In case that happen, is there a way to turn it back to normal?

 

Usually a BIOS/NVRAM reset fixes it.

Add a fresh windows reinstall to that. XTU doesn't always screw things up, but more often than not it does. It's a royal PITA to fix.

 

i7 7700K is known to run notoriously hot. Intel recommends not to overclock this CPU lol ..

It's a 4-5ghz chip on a tiny process, no one else does that but it's still going to be hot.

 

7700K overclocks just fine. Silly that the left hand doesn't know what the right hand is doing at Intel. Reacting to a reports of overheating and Lord knows if the people reporting it have a clue what they are doing, what kind of thermal solution they are using, etc., etc. And, Intel has been saying it's normal to push 100°C with Kaby Lake, so they can't have it both ways, LOL. Silly geese, they are.

If the Core Max OC Ratio is set to default (0 = Auto), then 4.5GHz is all you're going to get. Need to go into the BIOS or use the Clevo OC utility and kick that up to the maximum (83) then you can run whatever multipliers you want to, up to the functional limitation of the laptop. If you use XTU it will set the Core Max OC Ratio to whatever your highest multiplier is currently set to.

Here is a thread dedicated to overclocking. Feel free to ask questions there as well. Clevo Overclocker's Lounge

Generic questions will have pretty much the same answer regardless of what make and model you have. Things like what software to use for CPU or GPU overclocking, what monitoring software to use, etc. are brand and model agnostic for the most part. Although, Clevo Control Center is proprietary, most solutions are not.

 

I know... Dell's support team has the explanation ready (learned by Intel) and not interested in fixing their own mess when the customer complains that Dellbooks aka AWbook's are melting. Processors are meant for running 100C. Even 105C is within the normal

 

I would check your power connection is not coming out slightly when the speed drops.

 

It is plugged in just fine, These two cables are not loose at all. They are very tight fitting

 

I keep checking them and they are plugged in good and they are not hot. I do see the GPU getting hot a lot, but I only running one game or I am on my browser, the GPU (0nly one of them) 98C will get hot and the fans kick on, then once it shutdown, then another time a BlueScreen..... I still had the CPU OC 4.6 and -50Mv.... Is the GPU not getting enuff power when I undervolt the cpu? Any suggestions is much appreciated Or bad power cord, as I read here another person was having kinda same issue. Or is there better settings I can apply to assist here. Thanks!

 

The GPU should not hit 98C, speak to your reseller.

 

I Spoke with my "reseller" 10 times now via email and some phone calls, They refuse to address the issues i am having. They advertise free tech support for life, but I have not received any tech support or help with this issue to fix it. Does anyone have any advice for how to fix it or ? Also the CPU hits a high of 99C with the motherboard at 95C w/o OC. This is when I play some games. Thank you in advance <3

 

If you want to take it into your own hands then a re-paste and re-pad is the best way of bringing temperatures down.

 

Ok I can do that. Can you refer me to directions or videos and where to get the thermal paste? I assume I would want to use :Coollaboratory Liquid Ultra on CPU/GPU and thermal pasted on top or around it, as you can see it is my first time

 

That is the most extreme form but not required to have the initial impact.



Is my original guide, though others have produced clearer versions I don't have them to hand right now.

You could look at the contact pressure on your CPU heatsink, a 0.5mm shim would be the easiest way to improve contact if it does not look good.

The most complete method would be getting the GPU contact as good as my picture above, replacing the paste with liquid metal, de-lidding the CPU and using the bitspower skylake (not the kaby lake version as the skylake one is thicker) replacement IHS with liquid metal either side.

Keep in mind liquid metal is totally unforgiving. It is conductive and will eat aluminium it comes into contact with.

 

Ok good pic, where do I get the supplies to do this project? Thank you in advance <3

 

I used thermal grizzly pads and have in the past used phobya (not the XT ones, the blue soft 5 w/mk ones) without issue.

a 100mmx100mm square of 0.5mm and 1mm will do the trick.

 

Ok thank you for the information. Where do you get such items? <3

 

Usually searches will bring up places you can order "phobya thermal pad" should bring up some hits.

 

With the Prema BIOS, you can also disable the XTU Interface entirely.

As suggested above, an NVRAM reset will correct any alterations to the fan tables.

 

I also have a 7700k and 1070gtx, cpu -150mv, ram oc... i'm very happy with results and stability

 

Hey guys,

The best thing you can do for your Desktop-grade system, next from running the Prema Mod BIOS and making other tweaks (like an undervolt) is delidding.

Delidding the i7 7700k dropped my temps by ~20 degrees Celsius.

Currently running benchmarks.

 

yep true, i delidded with a simple slim wilson double edge razor blade, it took me at least 30min bcse i was very careful, but impressive results. i didnt put back any silicon in corner for more pressure, just in all surface grizzly lm.

 

You can as well try get your hand on Bitspower lid. Then lapp it and see if you can drop a couple of degrees more. But buy the correct one.

 

A very welcome suggestion. I'll look into it.

 

Don't forget to stick with the taller skylake rather than the kaby lake lid.

 

You, sir, are a life saver.
For these with the older P751DM2-G that can't hit the desired OC: This is the fix.

 

Depends on the level of your desired overclock

 

Well, 6.5GHz would be a nice place to start.
