Where can I find instructions to unlock 2080?

 

It could be that XTU/CCC conflict issue, if you have both programs installed. But strange problem non the less.

 

You mean power mod it by shorting the shunt resistors or vbios modding?

 

I don't know how. Hissy said that it's possible. I'm looking for this mod, maybe it's vbios mod with programmer?

 

Ah, I see. Can you keep it cool in the p775tm1? When I shunt modded my 1080, it ran VERY hot in my p775tm1-g. Only way I could keep it cool was with a vapor chamber.

 

Yeah it was hotter so I upload stock vbios. I prefers less fan noise with lower temps.

 

From what I recall, you should get best results by undervolting it to around ~0.950mV and pushing the frequency as high as that voltage allows.

 

If it weren't for these locks, 2070 would be more.... cost effective, as it's massively cheaper and the chassis has plenty of cooling headroom for un-underclocking it. Actually that's the reason i've picked 2070... But, locks.

As I described, weirdness persists even on clean install without XTU or CCC installed. And it first appeared without XTU in the system.
btw, do you know that CCC actually shipped with, installs and uses at least some components of XTU? If you install and deinstall XTU, then CCC stops working and throws XTU service related error, as these components get uninstalled with actual XTU.

 

You did upgrade or you bought 2070 with whole laptop?

I have GTX 1080 iin my P775TM1-G and I like that heatsink GPU is separated from CPU heatsink. I heard that heatsink from GTX 1080 will match 2070 only you need to choose correct thermoopades. Is it true?

Do I need to modify the heatsink if I would like to put 2070 or 2080 into P775TM1?

 

I noticed that CCC uses an XTU service, without XTU being installed. And when I installed XTU on top of it or uninstalled CCC, it went bonkers.

 

If you overlay the cards you are most concerned with inductor placement matching.

 

Bought with 2070. They have slightly different layout with 10gen.
As for separated heatsink, i noticed that additional link in combined version actually helps to cool down CPU, which is the much hotter of two here, despite being less power consuming.

In my case installing XTU over CCC or vice versa didn't cause much issues; uninstalling though obviously breaks things. Still, i normally don't use any of them (CCC is only for fan and backlight).

 

What program do you use to adjust that? I've got my CPU set where I want it but don't have any idea how to tweak my 2080

 

MSI Afterburner

 

With CTRL+F to access the frequency curve.

 

MSI Afterburner, you do need to do an .ini tweak in order to be able to limit voltage.

 

What performance do you have after overclocking? (Firestrike, Timespy gpu score)

In games my CPU never reaches more than 65-70 degrees Celsius so I don't need additional link . I'd rather not buy new heatsink because it's an extra $ 150. I'd rather modify what I have
but I don't know how serious changes I would have to make. Have you seen anyone do that?

 

With 8600k at 4,3ghz you probably don't need much cooling, yeah... what it is, 50-60 watts at peak?

As for scores. My 2070 is still locked at 115w powerlimit which totally cripples it. Via MSI Afterburner i've raised the maintained under load clocks from ~1500 of stock to 1630 @775mv, not a huge gain.
Still struggle with that power management buggery so can't give reliable benchmarks now.

Speaking of buggery. @jc_denton here's "interesting" hwInfo statistic showing another side of buggery. This collected during an evening of uptime, where computer wasn't loaded with anything heavier than browser (except one CPU-z load run) and went into sleep mode once. As you can see, at some point PL1 limit for some reason dropped to 40W. Only way to fix this is reboot, if I try to change it back via software it will just not care.
XTU is not installed, throttlestop is not running and wasnt launched at all, CCC is running.

Do you have any ideas?

 

Was this with c-states enabled? I have a feeling this is something to do with the windows power settings.

Set Windows to ultimate performance, reset and go into bios, set Max OC Ratio for all cores, have PL1+2 at 250000 and 300000.
Then go to "CPU Power, VR & Performance" and disable the following:

1. Speedstep: disabled
2. Race to halt: disabled
3. SpeedShift: disabled
4. HDC Control: disabled
5. CPU Efficiency: both disabled
6. C-states: disabled
7. PL4: 300000
8. PL3: 300000

See if that fixes that bug.

 

It's not mobile CPU. At 6x 4,3Ghz locked, and 100% load, CPU eats 120-130W in the highest peak.

That's why I'm curious about the performance at 115W. Maybe better pay extra and buy 2080 with 150W. But I also care about fan noise. So I'm struggling between performance and fan noice/temp .

Plz write your benchmark scores (firestrike and timespy).

 

I also have this problem where PL1 and PL2 get stuck at a lower setting then what's set in the BIOS. HWINFO is also not showing me PL1 and PL2 anymore....

 

err are you doing it right? here's my thing at 4,6 ghz and not fully optimised voltage after benchmarks.

(still hot af even at 100% fans, soldering is a lie)

you're welcome. CPU score may be off, or not, but GPU score should be "normal". It's slower than yours 1080...

* * * *

Now it's got even weirder.
After each reboot some of my settings in BIOS appear not what i've set them to ant not what they should be by default.
When I use F3 (optimised defaults) in BIOS, it changes some of those to defaults, but makes some others (like BCLK or CPU efficiency) disappear completely. Definitely something is wrong with firmware. I'm going to bother Prema once more...

 

That's CCC overwriting stuff in Windows. Uninstall CCC, set settings, test.

Edit: use autoruns to disable xtu service that CCC installs.

 

It is not, as it happens before windows even starts, and happens of a freshly installed system without any traces of XTU or CCC.
Gave it a try, with fully uninstalled CCC and XTU services still happens. Also, C-states seem to still work even when disabled in bios.
Also, CCC will not work without XTU services, it will give XTU related error at startup and silently crash on manual launch.

For now only change after doing your steps is CPU is now more limited under "balanced" power plan and reaches full clocks only under Ultimate; and Hwinfo doesn't read powerlimits anymore (but reads power consumption)

From your list, i don't have "CPU Efficiency" option, and of PL3 & PL4 I only have a PL3 menu entry with nothing in it. I'm not sure now, but i believe these were in place earlier.

 

Reflash the bios/ECU perhaps?

 

Very puzzling system behavior, but the system does not get stuck at 40W power limit under Ultimate performance after this, right?

 

The thermal interface material is only one part of the equation. It will be soldered

 

Debating between Area51m and NP9176/9156. I dont like that Dell has fitted bad mosfets on there GPU/MOBO or having two power bricks. Any suggestions on the best place to buy the 9176? Xotic sells it for a few hundread less with 3% discount then Sager. Any issues with the machine? Are they reliable with good components? I owned an old alienware Clevo model back in the day which was a disaster but it was second hand. I Really like what MSI is doing with the new GE66 Raider, thinking hard about it too but i dont know when it will go on sale. IV plenty of BGA laptops that are not cutting it for the type of gaming im doing.
How are thermals? What CPU is most appropriate for gaming as far as thermals? Thanks guys!

O one last ques, can anyone contrast the differences between the 17 and 15 inch, 9176/9156? I do like smaller footprints as it takes less space on my desk but I wouldnt mind having a 17 either, its been some time since iv had a larger footprint laptop. Are thermals comparable?

 

All our resellers offer the same base hardware it just comes down to who you get your support from in the first instance and any extras they might offer.

 

Not in Timespy. I Have about 7k in this test. Firestrike is much older so yes, in older games, which not using full potential of DX12, 1080 could be faster a little, but the diffrence is only noticable when you benchmarking. In real gameing is irrelevant. I am very curious about the differences in fan noise between 2070 and 2080 in P775tm.

In previous generation I tested 1060/1070/1080 and the 1070 was the most comfortable in fan noise generation.

 

They are less thermally dense this time around so they are closer to that 1070 level.

 

Maximum temp i've ever seen on 2070 is 71c, on auto fans. It can stay slightly above 80c on minimal fan even (happened because of bug). Main noise generator here is on CPU side.

 

Yeah the thermal density of that has stayed the same while the core count has increased.

 

Wow, that's what I was hoping for . I've got 6 core i5 so it's pretty cool in this laptop too.

 

So long as the frequency does not go too high the Intel chips are not bad on efficiency after all.

 

What your undervolt curve looks like in msi afterburner if you have 2080?

 

I would like to achieve default performance but with lower temps. How the curve in afterburner should look like? (RTX 2080)

 

Lower than the existing one, by an amount that varies chip to chip

 

Run that auto overclock scanner, it will give something close enough to maximum.

speaking of that... apparently my P775 9600k + 2070 combo is the fastest in 3dmark database, hehey.
but there are some entries of p775's with graphics score quite close to desktop. This bothers me. How they got around the powerlimit?

 

Congrats on that! You mean the 115W? Programming it directly onto the chip, the only way for 10 and 20 series of GPUs. You can visit http://forum.notebookreview.com/threads/mobile-pascal-tdp-tweaker-update-and-feedback-thread.806161/ for more info about that. I changed my 1070, so it is unlocked now, although you still have to watch for current and voltage fluctuations, cause it can just suddenly turn off the laptop.

 

BTW, I got a small problem. After some time of using and carrying the laptop, I started seeing bright white spots on the screen. As far as I got it, it is a pressure mark on the diffusion layer of the screen, so if you have something always applying pressure on the lid, you are going to get them. So I was wondering about two things: is it worth to check the screen by disassembling it and if the whole panel comes off to be replaced by another (in case I buy a new one)?

 

You can replace the panel if needed, do you have a g-sync panel? Usually the lid is fairly sturdy on these, but you should not place stuff on top of a laptop.

 

Nope, mine is not a g-sync one. BTW, can I install one, or is it impossible to change it? I was thinking of taking a 1440p 120Hz one instead of my 1080p 120Hz for visual clarity in case I need it.
It's true, it is sturdy, and I never place stuff on top of the laptop, but, whenever I'm moving it (and I did it a lot for several months last year) in the backpack, I place the power brick to the side of it, so, that's how it can feel the pressure, if I carry it on my back.

 

It is said that Clevo RTX cards are not supported yet.

 

My first line was you can replace the panel

 

I already wrote the message, but it got removed for some reason. I'm sorry about that, I didn't know that Clevo RTX cards are not supported. It just stated, that Mobile RTX is fine.

 

I meant, the G-Sync one. Is it possible to install it, if my laptop was shipped with a Non G-Sync one? I thought it needed some hardware on the MB to work.

 

Not without replacing the gpu, no.

 

Oh, so it has a special tag on it? How can you identify if the GPU supports G-Sync? I actually recently changed my GPU, but I don't know a lot about it, it seems like a usual 1070.

 

It's a resistor network change iirc.
