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

But it’s only with DSanke Bios. With Clevo original Bios it’s not. Weird thing.

 

Check in the bios that any wake on features are disabled.
Also all network boot functions to disabled.
Disable any automatic restart after System Failure. (select power off after System Failure...or something like that).
Disable fast startup in Windows Power Options and fast boot in bios.

 

Ok thanks I will try it.

 

Yes, I believe I do. Did you use CoffeeTime, by chance?

Also, what's your chipset?

 

You can download coffeetime 0.99 (the latest version of it) in this specific topic and post: https://www.win-raid.com/t3413f16-G...-and-Kaby-Lake-motherboards-94.html#msg144080
I own a Clevo P775DM3-G with chipset Z170

 

Also does it restart if you shut it off from the BIOS?

 

No, if I shut it of from Bios with the power button it stays off.

 

Sorry, I made a weird reply. I meant to ask Razor what his chipset was.

 

Hello,

After having installed the CPU my PC doesn't boot up. It shows a blank screen for around 20sec and then the fans go to full speed for around 30sec, the power led blinking orange and then my PC shuts down.

I don't think the bios flash was faulty because with my old CPU (7700K) it still boot (at least it goes to the UEFI boot screen)

Can anyone help me ?

 

Hi, maybe for a start you write what kind of laptop you have and what components are installed in it. What you did before and after the malfunction.

 

We need more info to help. What cpu are you using. Which bios did you flash. What laptop do you have?

 

Oh sorry. I was in panic when my Pc went intro trouble.
I have a P775DM3-G. I flashed it with dsanke Bios, the newest version from the link in this thread (page 234 or around it). The first boot went smooth with my old 7700K. And then I disassembled it to place a new 9900K (with two isolated pins of course). Then the behavior was described in the above message.
I removed the 9900K and replaced the 7700K. Now I had only black screen with no response. I disassembled it completely to reflash BIOS with external programmer ch314a, dsanke version in the first page. And now at least I can boot into Windows.
I don't think the 9900K was dead since I tested it with another computer with z470 board and it still works, can complete cinebench r23 for around 11800 points. But still, since I didn't have kapton tape, I cut some normal adhesive tape, which was a bit thick to cover those pins. I tried a lot to not accidentally cover another pin but I think I was somewhat inaccurate. Do you think that was the problem ?
Also can anyone recommend a trick to cut those tape properly ? It was really a pain in the *** with those tiny pins.

 

Which bios file did you flash?
Flash this one: https://mega.nz/file/aUZVVYJD#6l1mQt3awUn2eTe5ASfyWWzQeXhSojApMpuNknS6WVA
This one has the USB type c ports fixed and its the 1.07.29 bios

 

I flash this link, p775dm3, in the folder 100 200 original mod. With this version I can't boot
https://drive.google.com/drive/folders/1ZRLYpWUCwY9bsUpyEIVMrKQz7ID2JzEi?usp=sharing
And then I reflash with 1.05.11 in the 1st page of this thread and it work with my old 7700K.
At this point I don't know whether the Bios flash was bad or my handy work with 9900K was bad either.

 

Use the one I gave you. Has the USB type c ports working and its the bios for 9900k

 

Thanks. I will give it a try tonight. I have to disassemble it again because this morning I reassembled it for my work.

 

Make sure you use kapton tape in the two pins in the cpu

 

Also can you give me some tips about isolated pins ? How could you cut tapes into those tiny pieces ?
I thought the normal adhesive tape was too thick so I've just ordered some real kapton tape.

 

Just a lot of patience and cut the pieces as little as I could. It's a total pain in the ass

 

The normal duct tape doesn't hold heat like the kapton tape does. Don't use a normal tape or it will melt

 

Hello everyone. I am about to put a 9900kf on my p870dm3. Need to wait for some components, in the meantime I have 2 questions. Sorry if these are noob questions, but this is my first heavy mod on my laptop so I'm on better safe than sorry mode.
As for the pin mod, the post says you need to isolate 2 pins with kapton tape or any tape. Using standard tape is really the same, or it is strongly recommended to use kapton tape?
Second question is: my dm3 has a vc and a 7700k. I have been advised to delid the 9900kf with liquid metal. I'm going to reapply a Rockit copper Ihs instead of the original one. Would you relid it with gasket silicone or just use the motherboard brackets without gluing the ihs?

 

The first question: use kapton tape. It's recommended due to high temperatures. Normal tape can melt and damage the cpu

 

Thanks a lot. That was the part I was more concerned about. Added the second question if anyone wanted to share their experience on that.

 

I have a 8700k myself with a P775DM3-G but afaik the 9900k, people advise to delid it to keep temps low. Metal paste is not my thing so hopefully someone can provide more help

 

I never re-glue, I always just leave it loose and let the pressure of the socket hold it in place. Keeps contact to the core better.

 

A friend of mine has 9900K delid. He said that with delid + new thermal paste (I forgot to ask him what he used), he got around 5-10°C reduced at full load.

 

As far as I have read on the Internet the vc in the P870dm3 is GPU biased. I use myself a Grizzly Kryonaut for the GPU, but I am afraid it might not be enough for the cpu side.
Considering that with this mod I'm replacing a quadcore with an octacore my laptop was not originally designed to run, I thought liquid metal would be a must.

 

Delib + good heatsink contact + decent undervolt on the cpu side abd kryonaut.. It should be more than enough

 

Update 11/12/2021

So with BIOS 1.07.29 and 9900k properly patched I've been able to boot into Windows. I haven't tested with cinebench yet, but at least a good sign.
However I did noticed some strange things.
1. Clevo Control Center don't report CPU temps anymore. I have to use HWinfo. In fact, my CCC version was a modded one with XTU removed, not the original from my vendor (PC Specialist UK)
2. After boot I let my PC idling for around 5 minutes. CPU Clock was around 4.6 to 5 GHz although I did nothing. Temps was fluctuating from 39C idle to 77 and go down quickly at around 45. Is that normal ?

 

1. Install CCC 1.1.88 and everything should be ok.
2. Yes, because background process. (windows update, modules installer, telemetry compatibility etc.)

 

I've already had CC 1.1.88. A mod version without XTU as far as I remember.
I also noticed that I've Iost G-Sync too. I don't have my speaker here to check if optical output was working or not.

 

1. Do a cmos reset.
2. If you want temps shown and cpu overclock capabilities in ccc you need xtu.
3. What display do you have? Gsync will not work if it is not a native TM display.

 

That's why I said it was strange.
I've done a FN+D NVRAM reset. After that, there were some fine tuning to make 9900K stable as the default parameters make it crash immediately with cinebench R23.
Before this upgrade and with this version of CCC I always have Cpu temps reported.
For Gsync problem, how can I know display model ? I've also noticed that I don't have 75Hz refresh rate anymore.

 

Got some info from HwInfo64 about my panel:
LG Philips LP173WF4-SPF1
Can I get gsync back ?

 

Nope. you need either N173HHE-G32 or BTNHAN03.2 for Gsync to work.
Ah almost forgot, you alsoo need 40 pin Nvsr edp cable.

 

You can still overclock that display to 90hz using CRU

 

So for my understanding:
1. I can't get Gsync back because my panel simply doesn't work with new Bios.
2. At least I can get my 75Hz back with other tools. Or may be even better.
Is that correct ?

 

1) it's not that it's not supported, it's not certified for Gsync
2) yes

 

Just take the screen overclocking in small steps.

 

Thank you all guys. In fact I don't use laptop screen so much. Cuz I've already have another 32 inch monitor which is Gsync compatible. If I plug it in, would I be able to enable gsync ? I'm asking just in case because I'm on a business trip therefore I can't test it yet.

 

The whole signing thing is only for the internal panel, it does not impact external ones.

 

No it doesn't, sorry for the delayed response.

 

Still didn't work unfortunately.

 

Did you program the ECU too?

 

No, I haven't.

 

Might have been a bad program then. May need a full dump and flash.

 

Dump and flash?

 

Dump of a full copy from a working machine and flash on to yours.

 

Ahh right I see, is that something you can assist with or not? I have a P775DM3-G.

I appreciate the help so far, thank you.

 

Not a model I have, I just have the P870TM. Another owner could perhaps help.
