TONGFANG GK7CN6S / GK7CP0S / GK7CP7S

@genexis_x , maybe you can shed some light to a situation im having now. The selenite i'm using now, runs great and all, but 3 of the CPU cores tend to overheat and thermal throttle (over 10-15C difference between hottest and coolest core) while the other 3 cores temps are good. I've tried to repaste it, balance the heatsink and i'm using CM master gel maker paste. The temps were really good after that, quite balanced, probably around 5-6C difference between hottest and coolest core. however, the temperature difference will gradually increase over time, a period of probably a week or more, 3 of those cores will be back to overheating and thermal throttling state when pushed.

when that happened, i did a repaste again, and temps will go back to be good only to last about a week or so and it's back to thermal throttle. I've repeated this more than 3 times. At first i suspected the paste is not good, degrading over time, but then i tried recycling the paste (collecting the used paste from the heatsink and reapplying it back to the CPU die). Guess what? the temps were great even with a week old used paste.

At this point, i'm a bit at lost here, which is why i need your input or anyone who has experienced this or fixed this issue before. The heatsink is not balanced for sure which is why i tried to balance it and make it as flat as possible on the die contact area. what i can't comprehend is why are the temps good and reasonably balanced after the repaste and only after around a week it will start to have over 10C temp difference really quickly? and this happens regardless of new paste or recycled paste. Any thoughts?

 

It's because of the triple mount heatsink design. 3 of the cores on the bottom half (double side screws side) of the heatsink will inevitably have the thermal paste pump out as there isn't enough pressure on the top side of the heatsink (single screw side) to keep the paste over the bottom cores. I'm personally never going to buy another high powered CPU laptop with this type of heatsink again. Even using thicker paste I still have to repaste every few months.

 

so you are suggesting that the issue is at the area with very good heatsink cpu contact? i would think it's the opposite because right after a repaste, the cores that are still slightly hotter than the rest are the cores that became worse over time, not the cores that are cooler. logically, the cores that are cooler are the ones with the best cpu and heatsink contact.

but yes i agree with u, tripod cpu heatsink design is the worst!

 

Probably due to a poor fitting (caused by either uneven heatsink surface or uneven CPU die surface), causing thermal paste to dry out. Like what happened with my own laptop. I couldn't think of other solution except for heatsink lapping. This issue is common among tripod heatsinks unfortunately.

Edit: If you use TG Kryonaut for this kind of heatsink it will dry out even quicker. 1-2 days from my experience.

 

I was hoping CM master gel maker to be less prone to drying up due to thicker paste and that's pretty much the best paste you can source in KL that is an alternative to kryonaut.

Looks like we need to live with this handicap. sigh....

 

It's less prone to dry up actually. It just that almost any paste will dry out without a good fitting. I've repasted my laptop for 10+times. Probably reaching 20.

 

i'm not far behind. probably around that figure too. so did you manage to fianlly resolve your laptop cpu core temperature difference?

 

Unfortunately no. And Lenovo refused to change the heatsink (they say 95c is normal...)

I have no thermal paste on CPU and GPU but graphic pads. It is normally not the best solution but my temps with a 50mV undervolt never goes above 80-85 degrees celcius on both CPU and GPU.
With an undervolt of 100mV on CPU I have 75-80 as max.
Usualy I limt the CPU till 3.2GHz and GPU @1440MHz and than I reach only 70 on CPU and GPU in GTA V, Fra Cry 5 etc with good framerates (100+).

Maybe you should give it a shot.

 

Has anyone manage to make their own revisions on to Rev.Center 2? The code is open source. http://forum.notebookreview.com/thr...gk5cq7z-gk5cp0z.815943/page-336#post-10854080

 

to find out if you have serious core temperature difference, you need to run it at 4GHz all core turbo and stress it. I can get around that temperature too if i seriously limit the frequency of the cpu to 3.6GHz but i value performance over noise.

 

I found these old posts:

Scores of cinebench and Firestrike.
Tongfang GK7CP7S, i7-9750H, RTX2070, 16GB DDR4 2666MHz in dual channel (Kingstong HyperX CL15)
Cinebench R15 --> CPU 1310, OpenGL 124,21fps
Firestrike: Score 18386, 21670 Graphics score, 16921 Physics score and 9163 combined score
The cinebench scores stays around 1300 inevery consecutive run, pretty neat.

And

I've put everything standard, except the CPU is -100mV undervolted (setting in bios).
I played ghost recon: wildlands and noted these values:
- CPU pulls around 45-50W with amax of 60W, CPU temp around 80-82 degrees celcius with 87 as a max (also hottest core measured is 87)
- GPU pulls up to 120W, Max temp 82 degrees celcius.

I think these are pretty good values for a CPU and GPU with graphite pads.

So with a 0,1V undervolt and all the rest standard the CPU maxes out at 87 degrees and settles around 80-82 degrees with core differences of 3 degrees where 82 degrees is the hottest.
GPU max was 82 degrees, it hoovers around 78-82.
The laptop is making some noise than, if I game with headset I don't mind. Otherwise I start limiting the laptop.

If you are opening your laptop that often, testing graphit pads would not harm. Maybe this is a 'solution'. I'm happy with it, it never degrades.

 

what graphite pads are you using?

 

I have the IC Graphite Thermal Pad
https://www.youtube.com/watch?v=YpphKzmDiJM&t=536s

But Thermal Grizzly has also something
https://www.youtube.com/watch?v=um8QL-ts4RE

If you are using it. Be aware that it is electrically conductive as hell as it contains carbon.

 

Update on my core differentials. Using the same MasterGel Nano and temps were taken after 3 TS bench runs at 1024M size. Undervolt of -210mv core and -100mv cache

Core 0: 81c
Core 1: 77c
Core 2: 81c
Core 3: 78c
Core 4: 79c
Core 5: 78c

 

When did you repaste? and mind sharing how did you balance the heatsink pressure on the CPU die?

 

Actually i didnt repaste. If you remember my last post about the core differentials, that was the last repaste i did. I just left it there and occasionally used it as im back home for the hols with my main rig

IIRC i did not tighten the two non spring tensioned screws all the way on the CPU side. They still have about a quater turn left until they're tight while the larger one with the spring got turned all the way

 

i recently noticed my HWinfo can no longer detect CPU undervolt changes in real time. If i make undervolt adjustments in throttlestop, the undervolt changes are not reflected in HWinfo. the value for IA voltage offset and CLR are fixed. The only way for HWinfo to show the new undervolt changes is to quit the app and open again. HWmonitor on the other hand is able to detect the cpu undervolt changes in realtime. Even a fresh windows format did not resolve this.

Also, If i enable "disable and lock power limits" in throttlestop and let throttlestop start immediately with windows as @Mr. Fox recommended, my PL1 & 2 will not be detected (missing) in HWinfo. But i set a 30seconds delay before throttlestop start with windows, the PL1 & 2 appears in HWinfo but will be stuck at 70W & 85W respectively which kind of make sense because i did enable "disable and lock power limits" in throttlestop as @unclewebb recommended.

Any ideas as to why my undervolt changes can no longer be detected b HWinfo in realtime? and is there a way to show PL1 & 2 in HWinfo if i enable "disable and lock power limits" in throttlestop and let it start with windows immediately without delay? @Mr. Fox , @unclewebb

 

Does the monitoring table in the TS FIVR window show your voltage changes? That is important.

There are some bios and or Windows updates on the horizon that might completely block voltage adjustment. Be ready for that. TS reports this correctly.

I would not delay start ThrottleStop. It is a known HWiNFO limitation that it does not report some things correctly when using the Disable and Lock feature. Ignore HWiNFO and concentrate on your TS setup to maximize performance.

 

Place a shortcut to HWiNFO and TS on your taskbar or desktop. Immediately upon reaching the desktop, launch HWiNFO, immediately followed by TS. This will allow HWiNFO to read the PL1/PL2 sensors and (hopefully) launching TS within 2 or 3 seconds will allow it to override any firmware cancer that is limiting your voltage and power settings. It works this way for my MECH-15.

If ThrottleStop starts before HWiNFO64 does, the PL1/PL2 sensors will disappear in HWiNFO64.

 

Hi! I recently bought Eluktronics Mech-17 G1Rx and wanna do some undervolting. But the laptop has bios factory undervolt of -50mV voltage. My question is - should i turn this setting off in bios and then do undervolt procedure through TS with initial -125mV core and cash voltage ?

 

From my experience it's not needed. Start from -100mv.

 

I thought the keyboard of the laptop was typing good but nothing is true...
I want to use my monitor again in a good way, so I bought a new keyboard, it is a Ducky one 2 Horizon TKL (80% board) with Cherry MX brown switches.
The difference is night and day, the keyboard of the laptop feels like **** now, even on the first day. All errors are gone when I'm typing long emails or documents.

Maybe a flash of EC would help, but I'm a bit scared that I ruin anything. The support of the tongfong is lacking in this matter, otherwise it is a very fine laptop (it still is).

 

Most of the time I use my own mech keyboard for typing. MX Red lol.

 

I'm going to take a guess that the QC of the keyboard is shotty rn, lot people report that there needs to be a break in period of the keyboard which is true, I think the mechanical keyboard tray production is being killed based on the fact the next gen of TF uses membrane keyboards.

As for support, no vendor has a really good direct contact with TF rn.

What do you all think the thermals on the Max 17 would be compared to the mech 17 g1r? I'm considering bother of them. No reviews yet, but think the performance on the 2070 versions of both would differ much?

 

If TF is using anything new for their heatsink and fans or even vapor technology, we will see a difference. In terms of how much, idk, but most likely better consistency between units of the same model. Based on what I can find, the fans and heatsink are the similar.

 

The max-17 don’t have any Mini DisplayPort while the max-15 has two. What are you doing Tongfang?

 

This was bugging me too. I'm wondering if it's tied to the dedicated graphics and you could use a thunderbolt 3 adapter to mDP

 

This page shows a heatsink, but I don't know if it's the actual one. Doesn't look different to me.
https://www.illegear.com/laptops/onyx-pro-selenite-pro/

 

That's a 15" (can tell by battery size)
https://www.illegear.com/wp-content/uploads/2019/12/cooling.jpg

 

the keyboard is not good. I believe the issue is with the layout, i keep having typing errors, missed press or wrong activation. the travel is good, but key caps are wobbly. overall it's a poorly executed keyboard despite it being mechanical or optical

 

This review has some photos for the internal.
https://www.tech-critter.com/review-illegear-selenite-pro/
Note the top heatpipe on gpu is not connected to the gpu side heat sink. And only one heatpipe goes to each of the two side heatsinks.

A comparison photo of GK7. Note all three heatpipe on gpu are connected to the heatsink, and two heat pipes each goes to the side heatsinks.
Essentially they are taking the cooling module of the 15 inch model, and pair it with a 115w (125w?) 2070... Not sure if that is a good idea.

 

The layout of the keys you mean? I don't see anything wrong there. I just think that a mechanical keyboard that needs to fit it a laptop isn't a good idea.
I initially also choose a cevo P970 because it was typing better, but it had other issues where the TF is better. Oh wel, I use it mainly as a movable desktop with an extra screen these days...

 

Its a shame that they didn't follow what they did with the GK7. Aside from the actual size and thickness difference between the older 15 and 17in, the fact that they actually put a bigger cooling system in the GK7 made a ton of difference. I understand if the motherboard is the same between them but bringing the same cooling system just screams of cost cutting

 

Not sure, but it looks like the space is the same so maybe the old cooler could be used on this one. If so maybe cooling could be enhanced?

I'm also wondering if the battery could be swapped to the older model.

 

So the newer one is using lesser copper than the original, kind of disappointing that they are doing this. I'm guessing it's to save on cost and weight.
On the other hand,

I would really like a battery upgrade if they would just give us a new sub-board and a stock basic speaker,
What is the reasoning for not just making the battery bigger to the left when there is space and would give us a chance for a bigger battery without heavy modifications. (15" mounting?, seems like that moves the weight to one side, they could just have custom mounting points for the 17")

EDIT: If the next-gen 15" has basically the same cooling system and specs as the 17" but TB3 removed to force people to pay more, what is the worth of the 17" then, just TB3?

Might want to contract a vendor rep to try to explain the reasoning of the cooling, honestly thing it makes no sense when the cheaper model has visually better cooling than the newer model.

 

The top left screw on gpu heat spreader block the third heatpipe from reaching the heatsink. Don’t think it is an easy fix. The review also shows the gpu reach 87 degree redline in some games, although other factors might also play a role here.

Still, wish they have use the cooling system of GK7 on 17 inch model.

 

Hey guys,

I have an OP 17+ (GTX 1060). Has anyone managed / is it possible to get the dGPU to work with Hackintosh (High Sierra)? I have an unlocked BIOS which allows me to disable the integrated GPU (I am, however, scared to try it ). Has anyone done this?

Also, has anyone managed to get the sound working at full capacity (like it does on Windows with SoundBlaster Connect) on Hackintosh?

 

I'm looking at the thickness of both models and it seems that the newer one is thicker in the front and doesnt taper like the current GK7. Battery may not fit and be as thick as the QC7's one

 

MAX-17 definitely has a market (not for me tbh).
I think once we get the lg gram 17 types down to $600-$700 mark, I can see having a heavy 17" and lightweight 17". A lot of times, I remote with my lighter laptop while I'm on the move.

 

Why not a desktop and a light laptop instead of 2 laptops?

 

Can you please tell me where you got this bios, I need to do the same since I face some weird stutter when I connect an external screen

 

sometimes you do need the power on the go / outdoors

 

Just watched a vid on the MAX17. The cooling system is slightly different. Larger fans and heatsinks on the MAX17 but i think thats the only thing that was changed about it

 

Greetings,

I don't know if anyone with this chassis has had this happened to them but in CS:GO, for some reason, the CPU never exceeds 36/37w, and the CPU temperature sits at around 68/70º C.
Rainbow Six Siege for example, gets the cpu up to 55w and the temperature reaches around 85º C.

I'd really like to have a better performance in CS:GO but that power limit at 35w isn't helping.

Thanks in advance.

 

MAX 17 light review from Jarrod's Tech

 

I tested CS:GO yesterday on my laptop and the power draw of my CPU is also around 50-55W with it. I used my external display with 2160p resolution. So it is not the game itself.

 

Thank you for your input.
Can you tell me if you have your CPU undervolted?

Thanks.
