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

Later today Ill dump my BIOS and ill post it here.

 

Update 16/11

So far I've tinkered with the setting to get a stable 9900K @4.7GHz. I've test USB-C, and optical output too. Nothing unusual. Still no gsync with laptop panel but I use external display primarily anyway.

Now I'm needing some help with RAM. Did anybody succes with 3200MHz RAM. I've two sticks of GSkill 3200MHz CL18 and it's simply can't boot with XMP enabled.

I've read somme suggestions about using slot 1 and 4 but I'm so confused. For example on the mainboard, it said RAM3 and RAM4 but in CPU-Z when reading SPD info I see my two sticks in Slot 1 and Slot 3.

P/s: I've just noticed that in Bios the model was TM1 not DM3-G. HWInfo also reported TM1. I think the solution for it was posted long before but I couldn't find it. Does anyone remember ?

 

The bios for DM3 is a TM1 modified bios fyi

 

Yeah I've already known it. I'm just asking whether I can change it. I'm sure I've found a discussion in this topic about it but somehow I coudn't find it again
P/S: nevermind I've found it again ^^

Any tips about RAM ?

 

If I recall corectly from other treads, the solution was to up the voltage from 1.2 to 1.35. Better wait until someone else can confirm that?

 

There were a lot of discussion about RAM Overclock and frankly it's even more stressful than CPU OC.

I've heard about a Crucial Ballistix kit @ 3200MHz CL16 1.35V. XMP Profile of my Gskill stick stays at 1.2V

 

I confirm. Crucial Ballistix RAM user here. Stock BIOS. Enabled Xmp profile 3200 mhz at 1,35 v cl16.

 

P775DM3-G or P775TM1-G?

 

Oh damn! Sorry. My apologies. Guess I got too excited to be helpful. Didn't realize it was a P775. Just read this post where he wrote he has a DM3-G, assumed for some reason it was a P870. I can confirm 3200 mhz at 1.35v for my P870DM3-G. Don't know if it's the same for P775 DM3-G

 

After having tested all slots, I think P775DM3-G board simply can't support 3200MHz RAM out of the box. In fact, before switching to 9900K I've tried to enable XMP with 7700K without success. It was worked only with slot 1 + 4 which is single channel btw.

 

Here is the dump of the BIOS with 8th and 9th gen support and GTX and RTX support too and all usb type c ports working. Version 1.07.29. https://mega.nz/file/HI5wnDAJ#RuHiMdt6o-vIkjSIEDNkKjAM8UaGus9Yd4f778tEfMo

 

First part of the mod done here (P870DM3-G). Flashed the Bios via USB. Luckily no need to buy the SPI programmer.
Just one thing that may be helpful: you have to rename the bios file copied inside the USB to BIOS.bin for the command to work. For extra safety copied the file twice. One named BIOS.bin (bin file in property), the other named BIOS.bin.rom (kept as rom file).
Detached the original ihs, took the silicone off. Applied a layer of nail polish to the pins close to the center of the Cpu. Tomorrow I'm gonna apply the liquid metal and do the pin mods.
I'll try to keep you updated in case you might be interested.

 

Keep us posted

 

Good luck, just be careful with those pins on the motherboard and get that tape just so.

 

Thanks. So just to be extra clear (silly question warning), as I still haven't removed the 7700k I currently have on my laptop, so I don't know what to expect, it is better to apply the kapton tape to the mobo rather than to the cpu? Or to both?

 

You need to apply kapton tape to the cpu pins

 

Well the CPU pads, DONT TOUCH the pins on the motherboard, that's just asking for trouble.

 

The whole problem with the application of the tape is that the surface of the pins is less than a square milimiter in area so cutting the tape isn't difficult but getting the tape from your fingers is the real issue.
As a tip of what I used, use a tool like this:
Kapton tape has a special glue in one of the sides so it should stick to the pin and not more around even if you take the cpu out of the socket

 

For me it was the other side. I can "slide" those tiny tapes with my fingers but cutting them in good shape cost me 2 hours straight. I've used a nail clip.

 

Yeah it sucks but having the system running with the new cpu makes it worth the hassle

 

I have found that using hair scissors (the ones that come with the clipper) works so well for getting the tape to size.

 

This was the best I could do. What do you think?

 

Amazing work. Those are perfect

 

Ok. I call it a success. Far from finished though. Tomorrow I'll switch to cpu frequencies/voltage, ram profiles and testing. Tons of questions to ask.

Big thanks to Meaker and Joluke for the help.

 

Ok, I'll start to ask some of them. I'll try to be as precise as I can. First attempt went well. It took a couple of minutes but after some reboots (it did them by itself, I just pressed the button and started to pray) it landed on desktop screen. There I made a mistake. I turned it off, restarted, entered the bios and applied an undervolt of 80mV (which was what I had in my 7700k) and changed the Ram profile to xmp1 (again, that's what I had before for my 3200mhz crucial Ballistix) . Restarted again and it didn't boot anymore. I am pretty sure it was the Ram profile change to do that as I remember that I went through a similar hassle when I first upgraded my ram. I don't remember how I made it work at the end, but I can remember it was a nightmare.
So, took off battery+cmos battery to reset bios. Now it does boot again.
Any advise on what settings I can use as a start line to set voltage/frequencies in order also to test temperatures?

 

Glad to help buddy

 

Use throttlestop to change voltages. Doing so, you will be fail safe if you apply too much undervolting to the cpu offsets

 

So, I just want to tell my experience on this matter. I don't know if this is going to be useful to you as we have different models, but I am facing weird behaviours from my P870dm3, so I just thought "why not, maybe he's gonna notice some common behaviours" . I was sure it could run 3200mhz because that's how I run it with the 7700k before I switched to 9900kf. I don't exactly remember how I enabled the Xmp profile with the 7700k as I tried any combination of slot, but at the end I had 3200mhz with slots 1 and 2 (and as I remember it took A LOT of patience). BTW I have 2x8gb. I know that in order to get dual channel you need to use adjacent slots (so either the 2 at the bottom or the 2 under the keyboard)
Now, Dsanke mod done, I am trying to make my ram run at 3200mhz again.
Here are my attempts.
1)kept 1&2 slots. Just enabled Xmp on Bios. No boot. Reset the Bios.
2)tried 3&4 under keyboard. Enabled again Xmp. No boot. Reset the bios.
3)decided to go with 1 slot of ram to enable Xmp and add the second later. Used slot no. 2. Not only I couldn't boot, I couldn't even enable xmp because I couldn't enter the bios. Just had a loop of switching on and off. Reset bios.
4)moved the single stick of ram to slot 1. Didn't enable Xmp. It did boot. Ofc I was at 2600mhz. Restarted, enabled Xmp, and it booted again at 3200mhz. First successful boot with Xmp enabled.
5) added second stick to slot 2. No boot. Did NOT reset, just removed the second stick, and it did boot again, still Xmp profile active. Still 3200mhz.
6)decided to use the other stick, still slot 1, so took out the stick I was using, took in the other one. It did boot again, and in spite of the fact that Xmp on bios was still active, on cpuz I had 2600mhz (don't know why)
7)restarted, entered the bios, reselected Xmp profile, (which was already selected, basically changed to default profile and then changed again to Xmp, saved and exited bios). It did boot again, and this time 3200mhz also with this second stick.
8)added the other stick again on slot 2. No boot.
I don't know if this is normal. Basically I can run each stick singularly at 3200 but cannot pair them together.

 

Oh my, really hats off for your patience. I did give up with 7700K long time ago. In fact I could boot with dual rank 3200MHz XMP but also got many BSOD as soon as I launch some RAM Intensive apps like MATLAB or games. I've also heard that with @Prema bios the issues with Gskill 3200MHZ RAM (which I got) were fixed. Since I didn't buy my PC from Prema partner I can't benefit from his magic.
I haven't tried so much with 9900K and dsanke bios thought. In fact I'm gonna sell my sticks and get another kit 64GB 2666 since I need more RAM for my work

 

Thank you!! I shall try it as soon as I can and let you know the results.

 

Glad to help

 

Hello again,

Does anyone success in installing the custom audio driver in the 1st page. I've disable driver signature enforcement and also uninstall the Microsoft default driver. The installation of custom driver was OK, in device manager I've found SoundBlaster X720. (Win 11, P775DM3G bios 1.07.29). But the SB Connect App didn't recognize the device (Device not connected, check conncection)
Sound quality with Microsoft default driver is really horrible.

 

I have used your file and still no change, do you think I have faulty speakers? they're making a slight muffled sound every now and then but windows still doesn't seem to recognise them.

Thank you anyway.

 

Can be the speakers. The same happened to mine and had to replace them. Bought the new ones on ebay and everything works great

 

So, I've flashed the P7xxDM.rom and sound is back, my question is does that file support RTX? thanks.

 

Probably not. There is a excel file inside the bios rar that has the correct names to flash in OP

 

I've read it extensively, tried each and every bios file and this is the only one in which sound works, I'm so confused as to why. Is there anyway that I can add RTX support?

Thank you!

 

Do you really have a RTX card ? If not, better stay with GTX bios

 

There is not a benefit unless you do have an RTX card.

 

I have a RTX 2060 on it's way, should be with me soon!

 

I do yes, it's currently in transit to me so was hoping to get the machine sorted in time.

 

Which card do you have coming?

 

He replied in another topic of this bios that it is a RTX 2060
Here:

RTX 2060..

 

Now you know how to step back if needed but you will need an RTX bios to boot properly before you install the card.

 

I can get the RTX bios boot, I just have no sound unless I use the P7xxDM.rom that's my issue.

 

I can get the RTX bios boot, I just have no sound unless I use the P7xxDM.rom that's my issue.

 

That might be your choice if you want RTX support, go for a bluetooth or USB headset. It's unsupported firmware, maybe try again and see if it was just the particular path you chose?

 

have you tried my BIOS and actually install windows from zero?
I mean... i got the RTX bios working and don't have any issues with sound

 

I don't get why are you flashing a BIOS for another model that is not yours?
P7xxDM.rom is for P7xxDM1 not P775DM3-G!
P7xxDMx_RTX.romis the one for P775DM3-G with support for RTX and 9th gen
is the one you need for RTX and you can get the latest one from here:
https://drive.google.com/drive/folders/1ZRLYpWUCwY9bsUpyEIVMrKQz7ID2JzEi
Use the bios name:
P7xxDMx-0729-9900KS.rom
You are lucky you didn't hard brick your laptop because you flashed the wrong model BIOS to it
