P775DM3-G Overheat Advice

Was intended as info. Not directly aimed at you. People tend to forget what they have

 

Thank you!

When I take off the heatsinks, I will also have to re paste the GPU if my understanding is correct. Do I have to replace thermal pads on the CPU?

Do I have to clean them both using arctic cleaning solution? Is it better than isopropyl?

 

Thermal pads on the GPU/heatsink should all stay in place - I usually blast a load of photo's off as I am stripping the laptop down, just in case I have a senior moment when it comes to putting it all back together. Yes, you will also need to clean and repaste the GPU.

I used isopropyl, cotton buds and some lint free tissues for the cleaning. Yes, make sure everything is clean and shiny.

 

Just be careful so you don't damage the pads(if you don't have spare). Shared heatsink means clean and apply new paste on both Cpu-Gpu. Good quality isopropyl is more than good enough. Don't use water

 

Thank you for your help, dudes!

I will give my best shot at repasting after I try to play with voltages and such a few more times.

Seems that playing with certain things (voltage and clock multipliers) have unsettled a component in my MPC - HC + madVR chain and I get a lot of MPC-HC exited function and I also got a few times of GPU disconnected only because I played with my clock multiplier from BIOS. At the same time, I didn't update BIOS since buying YET, so maybe I do have some bugs.

 

The pads are sticky?

 

Mine did not fall off (twice).

 

Isopropyl alcohol has water in it. Unless you use the stuff intended for disinfectant of animals... then it's maybe 1% water.

 

Not using just water wouldn't be good. With Isopropyl it depends on the vintage, mine is 99.9% pure.

 

You can get it in different %. Higher %, the better. We have to use it in gasoline on older cars in the winter time

 

Yeah please send it to us... pay postage around 50£ and we'll update your BIOS

 

Are you for real?
Otherwise you will void the warranty?

 

Which BIOS do you have?

 

Delid thing, liquid pro and small tube of automobile black gasket silicone stuff ordered for under £30. Just in case I get the urge to delid the 7700K.

 

I have a feeling the itch will never stop for me until I delid. Might as well take my 6700K off OLX and delid it and keep using it since I have a dire feeling that 7700K being hotter won't be good with P775 even after delid.

 

I have a feeling you should delidde your chips yesterday You can still sell the chips for ok money although you delidde it

 

Will watch some more delid a 7700K vids on youtube to get off to sleep later...

 

Why would you pay for 7700k and lose its quality downvolting it, if you can get a stable 6700k or less for a better price and temp. Reason to pay and if you cant use its full power?

 

You can get more performance with a 7700k.
Try to fine tune both side by side.
End result will be better clock with 7700k, 9 out 10.
Simple as that.
For a user who doesnt want to waste time tuning, then the 6700k is probably better choice. Unless your BIOS already does undervolt, then a 7700k will work as good without the need to tune and out of the box out perform the 6700k.
Undervolt is not less power.

My issue with delidding is that...well I don't think I can manage the 'gluing back' part of the process without some help. On my own, I am almost certain that I will mess it up

 

Lose its quality downvolting it...?

Spoiler

Well, it is. It's not less performance (I'm guessing that's what you meant).

 

Those things not being available in Romania is a problem to me - otherwise it would had been done already. Not sure yet what to I glue the IHS back with or if I leave it floating tho I would like to avoid leaving it floating if possible.

 

I'm also curious why you say lose quality ? Is there any danger implied by downvolting? Also, I do just want a stable CPU, but my 6700K might be the lost one of Silicon Lottery as I can only go to 4GHZ before throttling and even so it throttles badly on the stock CPU in certain games leading to dropped fps. I can't believe that FiiO actually passed this kinda BIOS - I don't even reach 90C anymore but the stock BIOS will still throttle the CPU if the GPU is active. Everybody should be getting a @Prema partner lappy to fully enjoy them, Clevo's stock BIOS is really that bad...

 

The IHS glue is an automobile black silicone gasket seal, @Phoenix mentioned the name in a post somewhere. I have just ordered a small tube of black heat resistant silicone stuff by a manufacturer called CarPlan, which looks similar.

Permatex!

 

Just make sure the silicone is acid free, most car sealants are but worth checking. Test first, if you smell vinegar while its drying its has acetic acid, which not good for PCB's.

 

You could just order the exact stuff mentioned from Ebay

As to glueing it back on, if you purchase the tool from Rockit Cool you can also buy the re-lidding part to hold it in place whilst it dries. I did all this on my 6700K, but got DVC to do it for me on my newer 7700K laptops as they covered the warranty on the CPU and LM it for me[/URL]

 

I just ordered the Rockit88 and relid kit last night

 

Mine took around 2 weeks to get to the UK. Seemed to get stuck at Chicago airport for a week or so.

 

Am expecting a couple weeks as well

 

haha
Yes "less performance", i was already in bed and almost sleeping.

 

Oups, my bad, got confused. I've put them together: lowering voltage / decreasing multiplier / switching off cores/ lowering FSB to lowering the temperatures as this is my only target in the last days.

Dunno how to manage temps on 7700k. All kind of ideas coming to my brain

 

Whilst I am waiting for the new CPU(s) to arrive and try, I have settled on this.

1. Install @John@OBSIDIAN-PC version of Clevo Control Centre with the XTU Lite CPU OC feature removed.
2. Install the latest version of XTU from Intel.
3. In XTU, try Core Voltage Offsets in small increments below -100mV (I get no lower than -140mV without instability creeping in). Cache Voltage Offset is automatically linked.
4. Set all the turbo cores to x 42 (4.2GHz)
5. Set fans in Clevo Control Centre to Overclock.
6. Run a temperature monitor in the background and if the CPU is still hitting the 90's, resort to FN+1.
7. Put on a jumper and leave a nearby window open.

 

You mean 6700k?

The thing that scan says we test hardware before sendin, im wondering what test they do so they feel confident to send it to the customer. Or is it like "our tests include throttling"
Ive done few tests at stock, with-100mV offset stock bios I'll post screenshots soon. Not quite happy as yet.

 

I have also asked for another 7700K, just to rule out my 7700K being a potato!

 

With these settings, here is a screenshot of what happens during a 45 minute Nvidia Iray render using DAZ3D. The drop in temperature in the first quarter is where I decided to FN+1 instead of relying on the overclock fan settings.

 

You shouldn't have to sit inside your house with your jumper on to keep the bloody temperatures under control. That is ridiculous. It should run fine just as it is. Scan might have just sent you a potato indeed.

I remember that while playing witcher 3, the overclock fan profile will run fans at their maximum rpm and was able to keep the temperatures below 88C. Even photoshop and rendering work won't load cpu so much as to kick the fans in overdrive. I hope the 7700K would behave similarly after some tweaking

Something I have noticed, which is along the lines of overheating, is that the best place for the primary M.2 SSD is in the motherboard slot - as opposed to the drive bay slot. I have noticed the 950 Pro runs considerably cooler when placed in the slot behind one of the cooling fans.

 

A few minor tweaks and I can now get a render running for over an hour with temps below 90C! Well, what I actually noticed was the clearance on the bottom of the DM3 was quite low. It even looks like the base curves downward in the middle from front to back - so what I did was place some extra rubber feet, on the back rubber feet, so as to jack up the back of the laptop off of the kitchen table.

Left hand side of the graph was before jacking up. Right hand side of graph was after giving the base air intakes more clearance.

 

I'm having similar issues as to the OP. Stock system throttling with in 3 mins on AIDA at around 92 degrees. I updated everything with the Obsidian Tool (amazing BTW) and installed TS when ever it is open the Sound on system becomes choppy? And the under-volting wasn't sticking as they did the older CC, I was getting low 80's with a 125mv undervolt before and keeping the voltage at 1.2v.

Giving XTU a go with the setting as tried before hand.

Gave XTU a try. Set the voltage to 1.2 and gave it a -125mv @ 4.2ghz ran low 90s and throttled after 3 mins. Set the clock to 4.0ghz and never above 80 degrees for 25 mins. I dunno.

Pictures of HW monitor in next post.

 

Maybe it will be worth investing in a notebook cooler.

PS: That is an apt signature..3XS Carbon Extremely Hot

 

This is before under-volt, Both are playing Battlefield 1 for about 3 hours.



And this is after Under volt.

 

@EKcore - Just a casual suggestion: You might want to examine the paste. 10 - 12 °C difference between cores is kind of egregious.

 

@EKcore what kind of temps are you getting at idle? With fans just on auto.

 

High 30's low 40s Should mention this is with the OC fan setting in CC

 

Yeah I might have too. It seems some retailers suck at paste jobs. There should be an internationally recognized pasting course.

 

This was the original Scan paste job with MX-4.

 

Just got mine back. It seems to have came with a -100mV undervolt in BIOS. I don't really know how that would sit with TS undervolt so I just left both at -100mV to begin with. Just started running the AIDA, and temperatures don't look too bad. There is no thermal throttling and all cores managed to stay below the 90C mark. After ten minutes or so, temperatures are running in the vicinity of 80C. I will have to abandon the test now as I need to get some work done.

I think undervolt with some good application of thermal paste (thanks to @Phoenix for his advice on the matter) is going to do the trick in my case. Also, the new screen has absolutely minimum amount of backlight bleed and is an absolute joy to work with.

 

awesome stuff, just play a game session for 30 mins+ to make sure all is stable.

 

Well just as I was about to start some serious work, the coolers arrived and I had to test it. Well I installed the fans, and started Witcher 3. Laptops fans were using the overclock profile, notepal U3+ coolers were running at moderate speeds. I am astonished how temperatures stayed below 84C mark. I mean my 6700K was easily hitting 88C on all cores at max fan speed so I am quite happy with the behaviour of 7700K.
