*** Official Clevo P870DM/Sager NP9870-G Owner's Lounge - Phoenix has arisen! ***

I don't know. @Khenglish did the mod. Maybe he can answer. I do not have the laptop back from him yet. I was too scared of doing the mod myself. His soldering talent is advanced and I felt more comfortable trusting his skills than testing the limits of my emerging talent, LOL. I am only self-confident doing things that are not so tiny, like BIOS chips.

 

The ceramic caps are 22uF. The electrolytic is 470uF. The two rows in the middle are for the core voltage. The other caps are uncore. There were no empty core pads, but many empty uncore pads.

Mr. Fox is dreaming of far more clock gains that I think is realistic. Probably more like 20 MHz improvement on the core. I've really only seen cap improvements help GPUs a lot, and that's only on older cards.

Although the L3 cache and memory may clock significantly faster now, since the uncore had a very large % improvement.

 

So it turns out that of the 8 empty pads I filled, 4 are for the unimplemented power supply for the integrated graphics. As for the other 4, they aren't even listed in the service manual. They are C80, C118, C93, and C96. At the time I just saw the empty pads and filled them. I can check what they are with a multimeter, but then I'd have to take the palm rest back off.

Update: Looking at the picture I took though, C93 and C96 very strongly look like unlabeled iGPU power caps. I found C80 and C118 and they are VCCSA caps. I managed not to add any VCCIO caps, which probably would have been nice to have.

According to the service manual the CPU vcore has 33 22uF ceramic caps and 6 330uF electrolytic caps. I increased ceramic capacitance by 21%, and electrolytic capacitance by 24%.

Fun fact: The P870DM3 has the missing vcore electrolytic cap filled in, and it's pcb lacks the iGPU power pads.

Update 2:

I made an image labeling what caps are what:



I really don't like how I failed to add any VCCIO caps. Also for the memory voltage circuit there are 2 pulled 560uF caps, leaving no large electrolytic caps on memory.

I am considering re pulling the motherboard and adding the missing VDDQ (memory) and add some extra VCCIO caps.

Update 3:

VDDQ does have 2 smaller 220uF caps.

Update 4:

I have no idea why Clevo bothered to put in place a spot for an iGPU power circuit. The CPU display outputs are completely unwired.

 

Thanks so much for your time, really, thanks you

and what about the mod in the mxm slot?

 

The procedure is the same as what I did to the P150EM. The only difference is I used PJ67 to source the 3.3V instead of the 2 MXM pins:

https://premamod.wordpress.com/2017/10/10/clevo-pascal-mxm-standard/

 

Perhaps for quick-sync functionality or similar.

 

Anyone speculate when the next gen of this laptop will be out. I fancy getting a new laptop at the end of the year but I want the successor to 1080m

 

Mr. Fox
After the fashion 1080 I can use a simple card MXM 3.0 ?

 

Just a note that the guy from AHOC (actually hardcore overclocking) did not get too much of a difference if anything adding capacitors to the pascal cards and the mobile clocks are not worlds apart, they seem to simply be core limited.

 

I got nothing from adding electrolytic caps. Adding several 100 uF ceramic caps directly under the core eventually got me a single 13 MHz speed bin. Pascal's default voltage is extremely high for a 14nm process and the voltage scaling is terrible. I typically run my card at a 150W power cap and only drop around 200 MHz from unlimited which draws around 225W. That 50% power increase from 150W to 225W is only a 10% clock increase.

 

whether the video cards will turn from dm2, dm3, km, tm to my p870dm1? I do not consider the conversion of radiators as problematic.

 

Looks like they tucked a lot of the faster paths in the chip in to help efficiency in a narrower range. Plus the chips are already pushing themselves up so less headroom for manual tweaking.

 

Can I change the video chip n16e-gxx-a1 to a video chip from the desktop version? for example, on GPU gm204-200-a1? discard the video card?

 

anyone know where all the win 10 drivers can be downloaded from? i am putting mine up for sale

 

You can download drivers from our site.

 

Damn. Imma bug him now! This is a good excuse to turn on my DM3 and maybe with the power mods have the processor hold higher clocks and possibly stable voltage!

 

Just got it back from @Khenglish today. Now all I need to do is figure out how to get an 8700K CPU to see if it will boot and run with this special @Prema BIOS mod. And, build my GTX 1080 heat sink.

 

I got very good cooling by sticking on a Pentium 4 heatsink with a desk fan blowing on it. No power limit never got higher than mid 60s. It was a good holdover until I built the internal heatsink.

 

What mods were you thinking of doing specifically? idk how much better Fox's cpu will clock. I wanted to do memory mods too (2 more VCCIO caps, 2 0.6V caps, 2 VDDQ caps), but I had already put the motherboard back in and I was stretched for time.

Another mod I could have done was a vdroop mod. This would have involved exposing the CPU power plane on the backside of the CPU socket. Not only a time intensive mod, but an ugly mod. Definitely an effective mod though. I actually want to open up the power plane directly on my 3920xm CPU and solder directly from the core inductors, as the P150EM doesn't have any load line calibration.

 

There are some manual vdroop controls in the prema BIOS if you feel like breaking out some iterative testing.

 

Basically improving the CPU VRM's along with the Vdroop mod you mentioned. I dont know much about the memory mods though.

Ill shoot you an email

Im definitely not stretched for time, since the DM3 is literally gathering dust right now.

Also im actually working on getting waterblocks milled for the CPU/VRM and the GPU's in the DM3, definitely for the CPU first.

Nice!! Prema being awesome as always

Imma be back in the game in a another week or so.

 

@Mr. Fox

So does the CPU clock any better now?

 

He is likely still testing or been delayed.

 

I haven't tried going past 5.0GHz yet.

I am working on this at the moment. Will be done later tonight. Looking good... I think. Question is, "Will it work good?" LOL. I was able to use all 6 heat pipes, but shaping them to fit from DM3 to DM-G was a real pain in the butt. It does fit the GPU and chassis correctly as best I can see.

Spoiler: Teaser Photo

 

For those that care... looks like G-Stink works with 1080 in the DM-G.

@Papusan @Prema @Khenglish @bloodhawk @Johnksss @tanzmeister @Jon Webb

 

Here is a Fire Strike with the GTX 1080 running stock clocks. Looks like the heat sink works fairly decent for a homemade contraption. @Khenglish

 

Here's with a pretty decent overclock. Need to get my foam dam and Conductonaut on top of the IHS so I can keep the CPU cooler. @Khenglish, what thermal paste did you use on it?

https://www.3dmark.com/fs/15041455

 

I never repasted it. You said not to worry about the paste so I left the paste you had on and didn't bother to smooth it.

 

LOL, that's right. I forgot about that. It had Kryosnaut. Surprisingly enough, the application looked absolutely perfect. Flawless contact covering 100% of the Bitspower IHS.

I just fixed it. CPU still runs as hot as hell though, but not quite as hot as with the Kryosnaut. The DM3 ran a lot cooler and had a better 7700K sample. This one kind of sucks. Takes as much voltage for 5.0GHz as the one in the DM3 needed for 5.2GHz.

 

There is a fair amount of variation in the 6700/7700 series as you get up there in clocks.

 

Are you able to just set 5.3 ghz in windows and it still runs without benching?

 

Nope. This worthless POS 7700K sample won't even successfully boot 5.2GHz and takes around 1.500V to load Windows at 5.1GHz without a BSOD.

 

So the minute you set 5.3 it locks and reboots?

 

No, the minute I try to set 5.2GHz it locks up and/or reboots. 5.1GHz boots with 1.500V set in the BIOS. It's a really lousy sample. It takes 1.300V for 4.8GHz. and about 1.450V for 5.0GHz.

 

So that means the extra work done to the board didn't help?

 

I have no way of checking whether it helped or not with this CPU. I've never really had any interest in this machine with a single 980M without any hard mods. It was too weak and sucky at overclocking to even care about trying to play with it. I don't really remember ever trying to do much serious benching of the CPU before, so I am guessing it's just a really bad sample and I am only now confirming how lame it really is. It also never has been able to boot the Kingston HyperX Impact at 3000MHz, while I ran it at 3000MHz in the Tornado F5 and DM3. It ran the G.SKILL at 3000, but never the Kingston (for unknown reasons).

I will have to look in my Imgur albums and see if I ever ran wPrime or Cinebench at 5.2GHz on this machine. I don't think so, but I will check.

Edit: Just a crappy CPU sample. Looks like 5.1GHz is the most I have ever been able to squeeze out of this sample, and that is with way too much voltage for such a low clock speed. (See screen shot below for the best it has ever been able to muster.)

So, maybe someday I will pick up an 8700K for it and hope for better luck in the silicon lottery if it will actually boot. Until then, this will just have to do duty as a gamer-boy jokebook.

 

@Mr. Fox
Speaking of looking back... I just looked at the older memory benchmarks from the P570WM3 and they are much higher than anything we are doing today. Sure, it had a higher latency, but reads,copy's & write are all higher at 2400 mhz.
Each machine is different. So that is probably the case here. Just like the dm G/2/3 can"t run 3466 or 3600 or 3700 while the TM1 can.

Not sure about really bad samples since they start at 4.9 ghz as being bad samples go.... And SL seems to have them pegged at [email protected] on desktop boards.

 

Yeah, that's totally true. It could just be the limit of the DM-G motherboard is not as high. We NEVER got the DM-G to 5.0GHz stable with 6700K, so it's still a pretty decent improvement over stock. 7700K @ 5.0GHz and single 1080 is way better than 6700K and 980M/980M SLI or single 200W 980. What I am seeing is very much like what SL has pegged them at. So, not a bad sample... just typical or average sample I'd say.

 

I'm going to have to totally agree on that!

The part you forget is...It's only like maybe 3 people that can even deal with that machine in the world.

 

Yup, and the mere fact that it is running 7700K and 1080 are both things that "couldn't be done" so that's a huge win. More like they "didn't want it done" LOL. Can't sell new machines if people can upgrade what they already bought. What will be really great is if it can run an 8700K at 4.8GHz or higher with this Z170 motherboard. Not sure if @Prema got his hands on an 8700K to test in his DM3 yet or not. If it works that will be a huge win for that machine, too.

 

This is true.

 

Speaking of "gamer-boy" earlier this evening I played about 20 minutes of Crysis 3 in the most intensive battle (last chapter) against the Alpha Seph. Max GPU temp with all graphics settings maxed out with my home made heat sink was 80°C, so there's another win.



Nobody would ever come close to touching this with an Alienware, LOL. Still an Alienkiller in every way imaginable.

 

I may go by a board just to see what this 8700K can do....

 

It is unfortunate that such modifications remain the lot of a very small number of people who have access to software mods and instructions. Such modifications are made in a single sample, and this is more simply an interesting project than a guide to action for other users...

 

Modders Get "Coffee Lake" Chips to Work Stable on Intel 100/200-series Chipsets-Techpowerup.com
It turns out that "Coffee Lake" is pin-compatible with older LGA1151 motherboards based on 200-series and 100-series chipsets after all, as modders got some of these chips to work on the older platforms. Intel is using software to prevent Coffee Lake from working on older motherboards. This software comes in the form of the CPU's microcode, the iGPU's UEFI GOP driver, and certain Management Engine bootstraps on the side of the motherboard BIOS that lets it recognize the new chips. With the safe transplanting of these pieces of software, Overclock.net modders rootuser123, LittleHill, dsanke, elisw, Mov AX, and 0xDEAD; succeeding in not only getting the chips to work on older platforms, but also found ways to iron out several stability and compatibility issues. They've published a guide at this page.

 

very interesting, but we need to be able to use the i7 7700k in our obsolete P870DM, when will the bios be published?

 

Never. The sager / Clevo don't publish new bios, they want to sell new models.
And PremaBIOS is never ready too. So, it's more fast you sell the parts, and buy a new version, TM-G

 

Mr Fox, have a one 7700k running in one p870dm...

 

Yes, but he works for prema. And don't share the gold.
