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

Is the BIOS chip for P775DM3-G the GD25B64C ?

 

Yes, it could very well be a BIOS chip

 

Thanks a lot buddy

 

Glad to help) contact, how I can help you.

 

Still testing my new spi programmer, the Tl866ii Plus. If I need help I'll post here. Thanks

CLEVO P870XX Direct Die + additional vapor chamber cpu MOD

I am not openning a separate thread for this "mod", please read here if you are interested. I have decided some time ago to try out @ole!!!'s and JC_denton’s cpu mod with some light upgrades

STEP1: First of all I have bought a 56x56x3mm vapor chamber. This was the hardest part, as in Hungary it was very difficult to get, from Germany the shipping was like 25EUR. Finally I have found for approx 30EUR in Hungary so I have bought it.

STEP2: Second part - which is rather my idea - to put a direct die delid guard to protect the chip. The der3auer die guard is also rare and expensive, so I have looked for other options. I have found a 3d print model for the guard, so I have had them printed in different versions: 0,6mm 0,7mm 0,8mm height if you lap the die, you can have different height version. My i9 9900’s die is lapped a little bit, even though the 0,6mm die guard version fit to it, the others have light or no contact. I have also had them printed with better “plastic” which is good upto 150C just to be on the safe side.

My first thought was, that I needed to take out the motherboard to replace the cpu clamp with the die guard. Good news, that it is not needed at all, which makes this mod rather easy! You just need to remove the cpu clamp, and place the delided cpu in the socket and screw back the die guard. Of course the IHS from the cpu needs to be removed, clean of the cpu, so the usual delid stuff.

After it was done, I put the 56x56 vapor chamber on the die and TGC-ed both sides. I have measured where the VC covers the die in order to use as little TGC as possible.

I have done the same on the other (flat side) of the VC and on the CPU heatsink. Prior this I tried to flatten the cpu heatsink as much as possible. Also measured, TGC-ed both side, at there you go.

As the “usual” extra, I have installed my very favourite SEPA 5V fan as 4th fan. I have already done this fan mod on my previous 870km1, so I found 3,3V under the battery. On the DM3 needed a little "dremeling" to saw off one "pillar" near the memories, and the backplate to give space for the airflow for the 4th fan. Both took 5 mins altogether. In this case it is very slient but still effective. I have not got anypics about it atm, as soon as I open the laptop I will post some

You can see the pictures of the process below, and also some tests. It does not do a miracle, but still a good improvement, both temps and performance improved significantly.

Let me thank for @JC_denton for all the support additional time to help me understand his, I also share my mod for this great community!

Yes interesting. I was P870 km when installing a radiator from the tm version, for fastening the radiator, to the nuts on the motherboard, I just lowered the height of the nuts with a drill, by about 3 mm, almost to the level of the motherboard. and a new heatsink on the processor and the board fit perfectly. no need to install additional boards in this case, on the processor. which also affects the temperature.

 

I have already done the same, km1 to tm1 cpu heatsink, but it is far less effective than this one

 

Hi Guys,
A "friend" of mine constantly suffering to mod his quadro P5200 card into an old msi (gt70 I guess). Is there any clevo in which it could be put? If yes, what mods needed? Thanks a lot
