Let us know how it works out.

 

Hello,

Need to ask you guys, does the Sabre HIFI needs a driver to be installed for it to work? If yes, does anyone have it? Can't seem to find it anywhere.

I cant seem to use it if i plug in into the headphone jack, need to use the line out to use my headphones.

TQ

 

Just standard drivers, it's for the analogue output.

 

hmmm. if thats the case, the jack for the headphones is busted then.

It detects that i have plugged in a device, but cant stream the sound to it.

 

Do you get an audio pop when you plug them in, the chip should test the resistance of the headphones.

 

I did get some pop, and then silence.

Tried it on 2 different headphones, and both only hear the pop and then nothing.

 

Hi,
What is the latest EC for 870dm3? I have 1.06.1. Could EC have anything to do with sata ports?
thx

 

I/O would be BIOS normally.

 

I still have no clue why I cannot see sata 2nd port. I took out all sata/m2 ssd, but nothing. Tried different dsanke bios, nothing. However I have that the hdd spin up in the port, but it is not detected...

 

Could be a solder joint issue on the data side of the connector maybe?

 

Hi How did the mod go I am wanting to do the same thing just waiting on my heatsink to get here how did you cut the hole without damaging the heat pipes . Cheers

 

I'd imagine with a dremmel tool and by slowly and patiently taking his time. I would try and stick a small screwdriver under the plate just in case you should slip.

 

Hi thanks for that putting the screwdriver in between the heat pipe and plate is a good idea.

 

It is some accurate cutting.

 

Indeed, projects like this you want to take your time, measure everything, twice and then cut once.

 

Yep I am looking forward to doing some modding I have built and tinkered with thing all my life and the mantra measure twice cut once hold true

 

Hi,
I am checking you direct die concept What paste do you use between the 56x56 copper Vapor chamber and the cpu heatsink? Is there any risk that without die guard you break the chip? Also, what do you think, is it a stepforward comparing a 50x50x3 copper soldered to the cpu heatsink? I am considering the same mod, however I am not sure which one I would like to do (of course the more efficient)

 

I think it would be ok you would have about 2mm of thermal pad between the copper plate and the heat pipe, the copper plate and heat pipe would be of similar temperature the temperature changes once it gets the fins and fan area . With regard to the solder and copper plate and heatsink, a dermal and a steady hand should do the trick like its been said slow and steady.

 

I apologize but I do not get it. I have ordered 40x40x3mm copper block from ALI, I wanted to solder under the cpu heatsink, then go direct die. My point was it is a better version, or jc_denton's solution to use that 56x56x3mm small vapor chamber block. And also my question was, if he uses on both side TGC. Thank for you all kind help!

 

You got me on this one I have not thought about doing that sorry

 

Soldering a vapor chamber is going to be a bit tricky I would have thought?

 

I would not do it, it would get swollen I guess. I would solder the copper brick to the cpu heatsink, just like Mr Fox did in his youtube video, the Vapor chamber would be between the direct die and the cpu heatsink, as jc_danton did. The million dollar question, which one could be better

 

Thermal interface and things to consider:
It's liquid metal between the tm1 heatstink and the 56x56 vaporchamber, since it has the highest thermal transfer of 73W/mK compared to low temperature solder ~24W/mK. The heatsink has c-clips removed and pressure tightened by hand. VRM will need adjustment pads to offset the new height. Since the VC is 3mm it's very close to a stock Intel IHS and few adjustments need to be made.

I broke my P0, which was lapped thinner than an 8700K, in Dec '19 with a custom IHS and having too much pressure on the die. However, this R0 is lapped even thinner than that chip and it has held up just fine without the intel ILM and being mounted direct die to VC.

Original concept:
@ole!!! used low temp solder for the original mod and modding a direct die mate to fit with LM. A very good read

Optimal:
@ole!!! and I have had this discussion before, here are some of the points we had:

Remove the 0.5mm heatspreader plate from the heatpipes
- Plate doesn't cover 4th heatipe and restricts heat spread:
> this is how much contact the stock IHS has with the 4th heatpipe: https://i.imgur.com/5Fc6fqs.jpg
- One less thermal interface
- Imperfect contact
- Effectively creates a 0.5mm gap between VC and 4th heatpipe

Sand down the edges of the heatsink where VC contacts
- Ensure contact with the heatpipes

Lap the 4 heatpipes
- For optimal surface area

IHS and TM1 contact:
Heres a pic of the 0.5mm plate coverage and the poor solder contact underneath: https://i.imgur.com/Z1rrYUR.jpg

Removing the 0.5mm TM1 plate and lapping the heatpipes:
Lapping and flattening the heatpipes to add better contact is not advised. I did so on my old heatsink but the heatpipes failed after LM was applied. Idea was to go die>vc>heatsink without the 0.5mm plate as intermediary, as this would allow all 4 heatpipes to better contact the vapor chamber. Unfortunately one of the heatpipes failed after being treated with LM after lapping, likely due to me lapping them too aggressively flat.

Consequences:
lapped and flattened: https://i.imgur.com/QjvFyXR.jpg
lapped and LM treated failure: https://i.imgur.com/zBLyZvl.jpg

 

You could damage the fluid inside or just breach the chamber/warp it.

 

The only thing that took good time was marking out the areas where you want to apply LM between VC and heatsink and testing the contact between the two.

 

It does make the stud pattern clear on the vapor chamber.

 

While we're on the topic of vapor chambers...

Just got in my P870DM3/KM1 vapor chamber from China (via Ebay / Orange). I'm installing it into a p870DM2 with a single 1080, the second 1080 is in a holding pattern at 4 feet.

This sucker is making ZERO GPU die contact, with the included pads - I have a single 1080 in there now. Everything lines up, and seems to fit perfectly.

I'll be troubleshooting this a bit tonight, but am I just missing something? Are the included pads oversized, or is the heatsink not exactly the one I would need for the P870DM2?

 

Yeah, the pads are too thick.

 

Make most of them 0.5mm thinner and it will do much better.

 

Unfortunately they also impact core delta performance by a few degrees if you align it on an offset.

 

From the not flat surface I assume?

 

Surface is soft enough that when mounting pressure is applied it almost "forms" around the die, which is good. Though the the copper spacers, that form the patterns and are used for rigidity, cause small deltas since they are tiny pieces of solid copper. Which have a 10-100x lower thermal conductivity than the rest of the vapor chamber.

A couple degrees is just me being nit picky, but these 56x56x3mm vapor chambers are really good for hotspots in general.

 

That is the advantage of the vapor chamber, get that heat spread horizontally as well.

 

Hi guys, I just damaged my keyboard. Does this one fit on my P870 Dm2?

https://www.ebay.com.au/itm/New-Bac...016892?hash=item46bd61d83c:g:5rEAAOSwaQdf5sSV

Thanks

 

Yes

 

So all 3 models share same keyboard?

 

Yup

 

Btw, if talk about keyboard. Anybody has experiences loosing blue light on keyboard? Recently I realized that I have no blue color. All others work just fine If it is the ribbon cable, I am thinking finding the bad pin, and shortcut that with a wire, however some experiences for fixing would be good. Hard decision to buy another just for the sake of RGB

 

The ribbon cable is somewhat fragile, it can fail due to fatigue, ie. after taking out the keyboard many times. So I'd check if there is any noticeable damage around where it's folded.

 

That or it's internal delamination of that LED channel, either way a replacement would work.

 

Love my current rig (specs in sig), any upgrades to extend it's life?

Specifically, a CPU upgrade.

I did read something about unlocking the 1080 to a higher wattage? Don't even know what mine is currently set at.

 

Check mine sign's rig Check also Daffia Gamer dsanke bios mod thread, based on that you can upgrade upto 9900K(S). You can also unlock your 1080's vbios to increase TDP. I did not manage to do it though Always had black screen.
However with a 9900k you will have a monster, later on the 1080 can be also replaced with 2080(s). I have done it with my 870km1, worked flawlessly! Furthermore, you will not loose gsync from your screen (I tested with 775dm3), so all in all it is worth upgrading on cpu side. If only I had 870dm3 prema bios + EC for 8/9th cpu upgrade

 

You can put a 8th or 9th gen CPU inside but you need to short 2 pins. Your 1080 i think is 180 watt, you can flash the vbios for it for 200w.

Like @matyee says, he was faster

 

Four words.

1) Thank 2) You!

3) Awe 4) Some!

I'll check it out. My 1080 is *currently* meeting my gaming needs. It's the CPU upgrade that has me interested.

 

One more comment, be aware, that you MUST have delid for the 9900, otherwise it will blow up I have a delidded i9 9900 nonk, and I can use it 4-4,2Ghz with OK temps. Above that it reaches 90C with tests. I will try do the vapor chamber cpu mod to see how much it can help. If you do not need 8core, 8700k is a good option as well.

 

It's a much hungrier chip that's for sure.

 

Guys, which is the latest EC for P870DM3? I see 1.06.1 in bios...

 

Hey matyee, just seen the laptop you're selling. Nice. I have a DM3 myself and would be interested in the same modifications you made. Would go and purchase yours as it would save me a lot of trouble but I need to sell mine first so I can't make an offer right now. Just wanted to ask if you followed any thread/guide in your upgrade

See the Dsanke thread.

 

I'm sorry to keep bothering you guys but I have a noob question. I would like to upgrade my ram.
Currently in my P870dm3-g (stock bios) I have 4x8gb 2400mhz cl18 sticks. I am kinda sure I read somewhere that the higher frequency I can go for is 2666mhz, but the seller told me that the laptop supports xmp profile that can go higher than 3000mhz.
I have seen these sticks. I would like to know if they can work full speed in my laptop. I have a stock bios and a i7 7700k
