Official Coffee Lake Refresh Thread/BIOS for ALL Clevo Laptops - RTX CARDS NOW SUPPORTED

no. The OP had all the instructions I needed. Even the isolating of the pins with 1mm^2 bits of Kapton tape took less time than I thought. I spent about half a day extra doing a complete disassembly to get a SPI programmer read of the bios chip and seeing if the updated vbios would work with old cpu and bios

Gotcha! Is the spi/bios chip programming is necessary? Or you can just do everything from flash card like in OPpost?

 

Ultimately it wasn't required, it worked first time flashing off the bootable USB key.

I wanted a backup directly off the chip before I started in case I needed to revert from a complete brick scenario

 

Nice to know that the usb method works, personally I opened up my clevo to put another 4k screen in I just flashed the new bios and that was it. Its less hassle and it works 100% of the time if done correctly.

 

in these days im getting an i5 8400 for my p870km. what bios is the best for it ? the one on this thread or the other coffee lake bios in the other thread ?

also is my cpu heatsink enought to dissipate a 95 watt cpu? i chosed the 8400 because its 65 watt like my actual i5 6600 and cpu temp got max 75°.

also i have 2 230watt psu. with one i5 6600 and gtx 1070 im using a single 230watt. with a 95 watt cpu ill need to use both 230 watt ?

 

This one's for the "9th gen", you're better off looking at the 8th gen Coffee Lake bios thread:
http://forum.notebookreview.com/thr...kylake-kabylake-clevo-lga1151-laptops.821694/

The P870 heatsink is utter overkill for a "65W" CPU. The most I ever saw the i5-8400 with a -100mV undervolt in my brother's N950TP consume was ~55W at maximum turbo, 4.0ghz 6 core.

 

It's still a nice boost over the mobile chips at that speed though.

 

Some preliminary results

Firestrike physics: ~24500
Timespy physics: ~10650
Cinebench R15: 2025cb best so far (set to 4.9ghz at - 50mV, but VR Current Limit keeps it yoyoing between 4.75 and 4.85ghz)

The rest are at stock multipliers (so 4.7 all core), 150W power limit, -100mV undervolt, max fans, and the watercooling mod too (for now it's a thermal pad between the waterblock sitting on top of the CPU heatsink heatpipes. When the WC is on and the VC heatsink is cooled to about 20C, it really makes a difference and allows a 150W power draw to not thermal throttle.

Overall benches are rubbish, the GPUs are performing about 20% below stock on firestrike which is an issue I had before the CPU swap. Still have to flash proper power modded vbios on both

On air only it's a writeoff and about 100W is the max. The stock heatsink is *severely* thermally limiting to I'm guessing nobody's surprise. The 3 heatpipes just aren't enough to shift above about 120W of heat.

All my extra heatpipes have finally arrived and I can start building something better. I think I can fit 5, maybe 6 heatpipes on the heatplate after grinding down the various bumps and ridges. Trying to spread the heat to the GPU vapour chamber as much as possible to have 3 fans cool the CPU-only power draw.

It's a +90% to +95% multithread improvement on the overclocked 6700K that it replaced under a 150W limit, at about the same temperatures. At the same power draw it's a good 20C cooler than the LM-delidded LM-ontop 6700K which must be due to the lower thermal density of the larger die. And right now this 9900K right now only has EK paste (Ectotherm) too

x49 seemed ok for a short time until the throttles kicked in

Gaming is fine, steady 60fps on Mankind Divided @ 4K with a CPU temp in the 60s/70s. My 30-40 tabs in chrome open in a flash, really noticeable improvement there and in opening big excel spreadsheets and the little bit of video editing I did yesterday too.

@bennyg great results. Did you flash P870TM's EC? And what about G-sync. Is it still working?

 

Did you see our results? Everything on stock - without limits and watercooling - with single heatsink... Everything depend from Configuration. We have on p870dm3-g gsync on uhd display. For example P870DM-G don't boot anymore... On km works everything good. My tip is 8th cpu up to max i7-8086K because 9th generation Intel cpu is totally crap!

What do you mean it don't boot? So, after upgrading with 9900k it stopped to boot or what?

 

After bios flashing in P870DM-G notebook don't boot anymore...

My p870dmg booted with a 9900k, I tried it once more after bios flash as friend wanted me to delid it... Sad to say that thermals were absolute trash. 90c at 3.2ghz, thats below its base clock speed!

I recommend not putting an i9 in your machine without proper cooling! Unless you want your CPU running at 800mhz when gaming lol.

P870tmq heatsink will be needed. I will order it now, so in the future when I upgrade to an i9 I know that I won't have throttling issues. If only vapour chamber cpu heatsink existed...

 

No, still on DM3 premabios EC
Yes, still have gsync

Being only 5% behind that, with things still in such a raw state, is way ahead of where I thought I'd be.

The one @ole tried is what I might consider if a "moar heatpipe" heatsink doesn't yield acceptable results. Unfortunately it's aluminium so that not only means no liquid metal but soldering anything to it is also harder

 

With your water cooling mod's and radiator and extra heatsinks and solder, I thought you would be 10% higher....

 

We have tried with i5-8400.

The CPU heatsink is still the stock 3 pipe DM3, the copper block is only contacting with a big strip of thermal pad on top of the CPU heatpipes. It helps, but only by a maximum of 50W (i.e. with the CPU fan off, it can cool a 50W CPU load by itself to just below thermal throttle), so I doubt my setup is any better than the stock TM CPU heatsink.

50W is pitiful by watercooling standards, and always will be while it's connected only by thermal pads, which it has to be unfortunately, due to the overlap of the two heatsinks.

I'm planning to add heatpipes because from what I've read my calculated guesstimate of Qmax (maximum heat transfer capacity) of all the heatpipes comes out not much over 100W which means they just can't shift enough heat to where it's removed (to air/water)

 

The main problem I see with your idea is you need to convert it to a TM1 If you do that, then your idea will come together.
This 6 pound LN2 block is sitting flat on TM1 heat sink.
This would give you 100% contact.

Then mod the VC with a long copper water block and possibly remove the heat pipes marked in green to allow for your water pipes to run and use both fans to help cool it.
Speculations of course...

 

>2000 on cinebench is pretty impressive. How are the fan noise during normal use? Someone said before that the fans are more aggressive in ramping up.

 

Actually, stock automatic fan control was the opposite, it'd only spin to 49% duty cycle even when thermal throttling...

Compared to an OC 6700K, no worse. Max fans loud is still max fans loud.

I don't have CCC installed, I use Obsidian tools including Fan Control, with a ramping curve, and I haven't noticed it being any louder overall because
- my custom fan curve is set up to prioritise noise below about 60C which means without the water line active it all 3 (CPU + 2xGPU) idle at about 50C
- the same single/low thread loads use roughly the same power so sit at the same temp/fan% levels
- multithread loads that put a serious load on the CPU still spin the fan to full, but a fixed workload is completed faster

I find temperature changes on the CPU are less drastic than the 6700K too

The few games I've played are very similar temps and noise levels, 65-70C on Mankind Divided (frame cap 4K 58fps), low 50s in factorio (single thread 2d game)

 

hello again the i5 8400 cpu for my p870km was out of stock. if i order an i5 8600k or i5 9600k for almost same price, will it throttle or reach too high temperature ? my heatsink is the standard p870km 3 pipe.

i will not do overclock, but use default setting with maybe some undervolt like -75mv or -80mv .

 

I think Delided i5-8600k is better choice. You can give -100 or maybe - 125 UV. Everything depend from CPU.

Would also like to hear ppls opinion on which CPU would be the best for stable work with no overheating problems - 9700k or 9900k?

 

9900K all the way. just dial in the maximum stable clocks and voltages your heatsink can manage and profit from 8 cores with HT

 

A binned 8700K or an 8086K (delidded either way ofc) with upgraded heatsinks from the P775TM1 would be your best bet.

He has the P775DM3, the heatsink on that thing could barely cool the 6th/7th gen quad cores, let alone Coffee Lake 6-8 cores.

 

Always depends what you do with what u got its a unified heatsink so u can use the extra cooling capacity from the GPU side when its not in use. load during games should be lower than application specific loads, anyways. then use a high performance thermal paste (kryonat or LM), get urself a binned chip and be sure its delidded with LM between die and IHS.

from what ive seen so far, the P7 series could indeed take on 9900Ks at around 4.4-4.5 ghz all cores (properly tuned and voltage optimized) with higher clocks at lower core usage possible thats actually my upgrade plan

 

The DM3's unified heatsink was pretty sub-par though, it makes poor contact even with the toothpick mod and doesn't get much help from the GPU fan since there are still only 3 heatpipes going over the CPU. The P775TM1's split design is an improvement all-around, makes better contact and doesn't suffer from the heat bleed problem under combined load.

Good luck with your upgrade plan. I feel that while it might be feasible in short CB runs in a cold environment, extended rendering workloads or AVX would push it over the edge. You'd also need to do something about the fans because the old 5V fans just aren't powerful enough even at max speed for these higher core count chips. Idk if the 12V ADDA fans would fit on your unit.

 

ill be sure to keep you guys in the loop once my upgrade plan is initiated. i am curious myself at what kinda all core clocks id be able to squeeze out a highly binned chip in my unit staying optimistic though for the time being and keeping an eye out on 9900K power usage during heavy loads. only recently, brother @Falkentyne demonstrated a 125W power consumption with his 9900K set to 4.5 Ghz during p95 1344k avx loads, which would actually be right spot on for my CPU thermal headroom

 

I set my 9900K to HT off, 4.9 ghz and 1.25v.

Prime95 small FFT with 8 cores, 8 threads with AVX enabled had a max power draw of 175W.
(CPUSupportsAVX=1 and CPUSupportsFMA3=0 in local.txt in the prime95 folder).

 

i was referring to your 4.5 Ghz setting, forgot to mention the clocks but fixed that

 

My 8600K is only 6C/6T and it uses 150W in Prime95 1344K AVX at 4.5GHz 1.1V. So I'm not sure how 125W for 4.5GHz is even possible on a 8C/16T 9900K.

 

need zen2 for that one, it could probably do it with 8 cores with 7nm

 

dont ask me haha, im just the messenger here.

 

Max 116.9W
TSBench is similar to Prime95 with AVX (no FMA) apparently.

 

Hmmm that's not what I'm seeing?

TS Bench:

Spoiler

Prime95 1344K AVX/FMA:

Spoiler

BTW @jaybee83 I got my numbers mixed up. 1344K AVX/FMA is actually much lower than 150W as you can see above. 150W was in Small FFTs AVX/FMA ( ~5W lower with FMA disabled, not much difference). However I doubt a 9900K can do 4.5GHz in 1344K AVX within 125W, given that an 8600K is already close to that.

 

Did you use programmer or did you manage to do it just with usb?

 

Probably internal power measurements not being particularly accurate.

 

hi all again. today im gonna get my new cpu for my p870km. an i5 9600k ( was cheaper then i5 8600k) and is new version.
ill try to flash the bios in this thread and hope the usb stick works fine without the need to desolder the bios chip. i have also a programmer (sofi sp8-a) that i use for other notebook bios repair, but i hope i dont need to use it on my own pc

ive read that i need also ec flash from previous post to make notebook works with cc 2.0? i already have cc installed, but it say its version 5.0001.1.54

 

I did not TOUCH the ec and everything worked fine. If anything goes wrong with flashing the ec you could brick the board. I wouldn't risk it!

But, if you know what you are doing then go ahead.

My mistake: you have a p870km go ahead and flash the ec, you need to so you can install the new control center.

 

Hello everyone, i've been lurking for while forum and decided to try this mode on mine P870KM1-G with GTX 1080 and i5 8600k

Writing this to warn you - i didn't get to BIOS installation part.

I almost fried my notebook because of vBIOS proposed for this mode. After vbios update it is UEFI x3000A (mine stock is x30002.

So flashing vbios went well. After it i wanted to check is it stable - so i ran regular Firestrike test on max fan profile. I noticed after few seconds that there are FPS drops. Than Screen went black and after 2-3 seconds whole notebook was off. Couldn't get it ON after that - my first though - fried GPU because of faulty vBIOS. Than i realized that my power adapter is off to. Tried with extra adapter from MSI laptop but no luck

Decided to dissemble laptop and try NVRAM reset. Couldn't believe but it helped. Laptop turned on and screen was working (so GPU should). After it i flashed back my old vBIOS and ran firestrike again. Everything went fine with max temperature 65C.

Flashing this faulty vbios cost me power adapter and battery (it is not charging now - stays all time at 0%).

Idk is it possible to flash this bios/ec without custom vbios.

@dsanke - i think you should take closer look at this vBIOS. I am not only one who had problems with it - but i guess only one that almost fried notebook.

 

wowwwwwwwww im back after new cpu installation. all works really fine. just applied for now a -100mv undervolt. while gaming cpu temperature was around 60° celsius... and now on my game i never never went down 60 fps.... good stable 60 frame in all scenarios. im really really happy with that.

just now have 2 things to fix and im all ok
1: how can u remove the freewere bios warning when powering pc ?
2: how to flash the ec file? can i use the efi usb pendrive ive created to flash bios to flash now the ec firmware ?

audio is working again after driver reinstall. some jack now has changed while before i had front speaker now its optical, but all is ok and sound seems working better.

im really impressed by now for the speed of my pc that infact is a notebook with extreme performance...

tnx everybody for the help and tnx for the developer for making that great bios mod


ps: monyku what vga u have ? i have 1070 and with uefi version ok already from store.

 

@ScruffyITA i am also grateful to dsanke for all work - i think it's amazing. About GPU - it's 1080. Someone mentioned in this topic also that graphic perform lower by 20% - maybe you have same issue.

 

i did a vantage test and score is 10k higher , also gpu values are highrer now.

before i5 9600k i had a i5 6600.

 

Awesome! Did you manage to do everything just with usb or did you use programmer?

 

all by usb. was really easy to do it. i also saved my original bios

 

quick question did any1 try 8350k on a 65w would it just run at stock speeds 4.0ghz? or it requires additional bios modding?

 

It would run the default 4ghz speed.

 

@Monyku I don't know what cause your problem because the vBIOS are from Clevo , I did and can not edit them because if I edit them it won't pass the security check of nvflash tool . I just removed the old GOP and paste new one on it .
GOP is a program to make your screen work with pure UEFI boot .
The GOP is from NVIDIA too .
If you do not update GOP , according to my test , the BIOS from TM series won't let you boot .
@ScruffyITA And the "freeware" tips is inside Logo picture , you can replace it with whatever method you like .
I usually use UEFITool to do this.

 

tnx very much again for the good bios. was not me having problem with the gop and nvidia driver i did no error or any problem doing the upgrade. tnx for the tips on removing the logo, ill do it later
