Clevo P775TM1-G questions

XTU sometimes will go nuts if you made changes using Throttlestop.
So if you want to use XTU don´t use Throttlestop, if you already used Throttlestop you will need to do a Load Setup Defaults before using XTU.

If you use Throttlestop then you don´t need to use anything else.

If you use CCC you shouldn´t, get rid of it.

If you decide to stick with CCC then only god knows how will it play with XTU or TS.

If your objective is only to do a bit of undervolt you don´t need any software, it´s really easy to do that in the BIOS.

 

Thak you! Actually, i've already removed XTU and currently thinking about removing CCC. At the moment, i dont need several profiles - going to make an comfortable undervolt and live with it (and sure i could just define this Vcore offset in BIOS - moreover, i have PREMA mod BIOS). But, XTU can be useful in the optimization process - when you tuning different parameters (like Vcore offset) and making some stress tests. After you've defined appropriate parameters values - XTU can be removed and values can be used somewhere else (ThrottleStop, CCC, BIOS whatever).

By the way, is it reasonable to play around with some other than "Vcore/cach offset, Power Limit 1/2 <-> tau"?

 

The only reason I use CCC is because I like to notifications that pop up when you enable caps lock, max fan speeds. If Obsidian control center does this I'd switch in heart beat.

 

Well, there is another reason - keyboard lights. How can i "operate" (enable\disable\change collors\change intensity) it?

 

Obsidian Control Center does it

 

Is it better?
Is it free? ( ) )

 

I've reduced graphics in BF5 to high without DXR and all these staf - CPU not more than 80 W (4600 MHz, and 80 degrees - by there was cold in my room. not sure how exactly) GPU nearly 100% load and 90-130 FPS.

If you have some more concreate request (about how my system works - you can ask me).

AND waht about this : "By the way, is it reasonable to play around with some other than "Vcore/cach offset, Power Limit 1/2 <-> tau"?"

 

Depends how far you want to go, for a nice comfortable 24/7 setting then it's not worth looking at other settings.

 

Am i correct in limiting currents on 150 A using those considerations, that even on ~<1 V it corresponds to huge 150 W (and for higher voltages that will occur on higher frequencies or CPU load it will reach even bigger values) and due to the fact that i have limited the power in less than 150 W this 150 A limitation is adequate.

 

Depends how far you intend to push it and under what loads.

 

I mean, is it correct to assume Vcore * Icore = Pconsumed (cause i'm not sure if this "I" or current that i can limit includes all currents drained by CPU same as for "V" or voltage - cause cache has it's own limitations for example)

It's simple school physics, but there could some factors that i've not counted. Currently i've assumed this simple formula: Vcore * Icore = Pconsumed.

 

It has more features, but most of them are not free. Some say it's better then the CCC.

 

That's power for the chip, not for the vrm as well.

 

Hey, guys, what do you think about "Lenovo Y Gaming Armored or "Dell Alienware 17 Vindicator v2" or may be some other model? I'm looking for safe and comfortable backpack for my P775TM1-G

 

Evereki Titan or beacon are pretty top of the line.

 

Both seems prety, but as i've seen from review ( - 5 min) they have weak bottom (possibly it also a problem of all BackPacks in case of using large/heavy laptops)


btw, i have "commute sleeve" now.

 

Is it dangerous to feed a 9700k by 120 W (in stock PowerLimit 1 is set to 95 W) on P775tm1-g ?

Is it reasonable to increase frequency multipliers a bit? Higly loaded CPU (with PowerLimit 1 shifted to 120 W: LINPACK without AVX - 110 W and holding frequency at 4600 MHz, LINPACK with AVX same as Prime95 small FFT - stuck on 120 W decreasing frequecny to 4300 ) CPU goes in throttling by power usage. But due to the fact that in many tasks CPU is not loaded "fully" - there is still a place for maneuver (different tasks load CPU in different ways and it's hard to estimate real "CPU loadness\load" cause a lot of factors: vector instructions (AVX/SSE/... with different vector size), cache using, etc... -> for example CPUz stress/bench load CPU for 100% in accordance to Afterburner but in the same time require only 80 W instead of 110W in case of LINPACK ) and so here increasing of frequency could increase perfomance for such "not fully" load cases like CPUz bench or smth. And in case of hard load like AVX - CPU will decrease it's frequency in both cases: whether it's turbo freq. would be increased or not.

P.S. Currently i am just trying to understand what performance can be achieved with my system but in common i'm going to use safe 95W-1s-120W + (-130 mV undervolt) scheme.

 

Is it "safe", that's always tricky with overclocking.

 

Is it reasonable to increase frequency without increasing of PowerLimits - so CPU will work on higher frequency only at low load, at high it will fall to some lower frequency corresponding to PowerLimit. Please, answer this question. For example, increase frequecny to some 4800 MHz or even 5000 MHz but CPU will fall to 4300 MHz on AVX high load due to Power restrictions (for example 120 W) and will fall to 4600-4700 MHz on non-AVX high load.

 

That's what turbo is designed to do really, not increasing power limits or voltage will tend to avoid issues.

 

Is it ok to leave unfixed frequency or i should fix frequency so it will be always the same value no metter how much it loaded? (Some guy on other forum said me that when i'm overcklocking i should fix the frequency to avoid throttling and tune Power Limit that will setisfy this frequency but he has not proved me that it's good idea - i'm still unsure about that - is that throtling so bad?! Will the throtling like oscilation between 4300-4400 MHz or smth. influence my gameplay??)

 

Fixing can help fine tune 100-200mhz extra where as dynamic will keep it cool at idle.

 

Assume different load: non-AVX (work on highest frequecny, for example 4800 MHz), mostly non-AVX - heavier than previous one (during it's work, freqency decreased a bit to setisfy Power Limit - for example oscilations between 4400-4500 MHz), mostly AVX - even more heavy than previous (during it's work, frequency decreased strongly to setisfy Power Limit - for example oscilations between 4100-4200 MHz ). One guys from another forum proposes to remove Power Limit but limit the frequency on the level where other than power factors (like temperature, current etc.) will not provoke throtling - or in other words he recommend to decrease the frequency in this hypothetical situation to 4500 MHz or even 4200 MHz. He said that this throtling and unfixed frequency will strongly decrease the comfort level in work or games. And currently i'm dissagree with him - cause in that case i will loose in performace - in our example on non-AVX case i will loose the posibility to work on 4800 MHz. He also mentioned G-sync and DPC latency and said that unfixed frequency and comfort lack somehow related to G-sync and DPC latency. Could you comment it somehow?

BTW, i've made few tests for laptop in three modes: 1) Stock (95W - 1s -120W, 4600 MHz), 2) Undervolt (95W - 1s - 120 W, 4600 MHz, Vcore offset = -140 mV), 3) Light Overclock (120W - 1s - 145 W, 4800 MHz, Vcore offset = -140 mV). As for overclock - tested also in LINPACK and Prime95 for 1hr and no errors (i know i should do it for longer - like 24 hrs to be sure about stability, but too much time for me for now). All three configs have been tested in stresses (CPUz, Furmark, CPUz+Furmark / Prime95 small FFT, Prime95 small FFT + Furmark / OCCT LINPACK (non-AVX), OCCT LINPACK (non-AVX)+FUrmark) with afterburner monitoring + syntetic benchmarks (Cinebench R20, 3dmark TimeSpy+Firestrike).

And one more question - is it possible to optimize GPU in my laptop or it is already optmized? I've tried to use afaterburner but PowerLimit for GPU is locked (i've checked afterburner options - didn't help), Temperature Limit is locked and it's "built in scanner" do nothing (actually when i'm launching auto-tunning at first it scan/tune and overclock it but during testing laptop goes in restart)

P.S. All these overclocking is just for better understanding of my laptop - i'm not going to use it in real life/real applications - i will use it in stock 95W with undervolt cause currently it's even more than enough for me and i want it to serve me at least 5 years.


THANK YOU VERY MUCH for attention and help!!!

 

On other forum guys gave me an advise to set the "override" mode for voltage (instead of "adaptive" with negative offset) and to decrease frequency multipliers (frequency) to values where no throttling occurrs (thermal, power etc. - for example no throtling by PL1 - power limit). They said that such oscillating frequency (during heavy load it will fall to some lower than maximal values) will result in lags in games. Moreover, they advised to turn off all ENERGY-SAVING options but i dont know which of them in BIOS exactly ENERGY-SAVING - i've found such options and tried to change them to check if given recommendations are reasonable (Voltage Optimization - "Disabled", Race to Halt - 'Disabled", Intel Speed Shift - "Disabled", Energy Efficient P-state - "Disabled", Energy Efficient Turbo - "Disabled", TVB Voltage Optimization - "Disabled", Voltage Mode - "Override", TurboBoost short power max - "Disable")

What recommendation could you give for CPU configuration on my laptop? Not just OK configuration, but the best in you opinion. I should admit that i'm considering few working scenarios - one with low temperatures and power consumption (like 70 degrees and 60 W) and other with maximal reasonable consumption (90-95 degrees on 120 W).

Currently, my choice is to just set the frequency multiplier to the highest value (48 for example to obtain 4800 MHz), set the PL1 to the desired consumption value, set negative core voltage offset (lowest value with stable work). Voltage in "adaptive" and frequency will "oscillate" - depending on load it will fall or rise to satisfy given PL1.

What i've found and changed in BIOS:

(Here how this two configs goes through LINPACK, just to show that it's working.)

First... Avoid using Furmark.

You can choose AVX Negative offset option in bios and add clock frequency for this type load. This means you can run max Clock speed in all other types workload.

https://www.tweaktown.com/guides/8481/coffee-lake-overclocking-guide/index3.html

You have also another great options... ThrottleStop whitc can give you 4 power profiles you can switch between with a simple key comand on the fly.

 

It's a bit like the furmark limited the GPU manufacturers put in because no game is actually going to load it that much otherwise.

 

I know about AVX offset and i understand that different tasks (programs) could load GPU or CPU in different way (using different CPU/GPU computational blocks) that will result in different required voltage and different power consumption. Actually, i have already tested my laptop in different tasks to investigate this. What i'm asking now - is to how to configure my laptop - first of all how to configure CPU. There are a lot of possibilities, a lot of options. Could you propose your best configuration? And please read my the last message here, look the pictures (if it's possible - probably you have no access). Thank you!

P.S. Here some results (i have a lot of interesting plots, but it is too much to post here ) of my investigation for my laptop:

First plots for temperatures of CPU and GPU on heavy load (furmark and prime - only CPU load and both CPU/GPU loaded for 100% with different PL1 values and so with different exact value for power consumption)


And here plots for "frequency drop" that occurs due to PL1 (power limit for CPU) with different tasks (three synthetic load and Assasin Creed Odyssey with low preset - both figures are same but one with legend)


P.S.S. And i am terrible sorry about my language.

 

If you want to get the sweet spot then you need to characterise the chip first (voltage vs frequency) and pucj thr spot along the line that meets your desires.

 

So what options in BIOS should i use (turn OFF or turn ON, what parameters should change or specify in your opition)?

Please, be specific as much as possible.

LIke instruction - disable that, enable that, change that parameter to such value etc. And i will test both configurations (will investigate Frametime behaviour in Assassin Creed Odissey, it's statistics)

 

(And about you recommendaiton about voltage/freq profile - for different tasks i assume such curve will be dfferent)
- the voltages (in adaptive mode with negative offset -130 mV) it's for the frequency picture above

 

You basically need to choose a point on the curve you want to run. What measures are required depend on where you want to run. If it's around 5Ghz then yes there are secondary power targets and such that need to be adjusted and cooling considerations.

4.6GHz not so much.

 

What about all these: (Voltage Optimization - "Disabled", Race to Halt - 'Disabled", Intel Speed Shift - "Disabled", Energy Efficient P-state - "Disabled", Energy Efficient Turbo - "Disabled", TVB Voltage Optimization - "Disabled", Voltage Mode - "Override", TurboBoost short power max - "Disable") and ("override" mode for voltage (instead of "adaptive" with negative offset))

Could you answer to those questions in my post - Why static voltage?, Should i decrease frequency (avoid throtling by PL1) or oscilating frequency is OK... all this staff - i want to check your best option with my semi-default version (4800 MHz, -130 mV offset and PL1 at specific values: 60 W, 90 W, 120 W)

 

These are all standard overclocking questions or term definitions.

https://www.google.com/amp/s/amp.re...s/78oh9v/question_static_or_adaptive_voltage/

For example.

 

(As far as i understood - there is no LLC in clevo)

But what about all those options in BIOS??

 

Hello, again!

Why is the power limit for RTX 2070 is on 115 W while cooling system can dissipate up to 150W (assuming 150 W limit for RTX 2080)

Is it possible to unlock this hidden potential for my RTX 2070? (write changed VBIOS i suppose ). Currently just want to know - not going to change stock GPU bios.

 

Ask Nvidia http://forum.notebookreview.com/threads/clevo-2019.826781/page-2#post-10843215


http://forum.notebookreview.com/threads/nvidia-thread.806608/page-178#post-10860338

 

Probably, they are trying to make RTX 2080 more attractive this way?

 

You do have a weaker VRM on the 2070 board.

 

Oh, i see. So, is it reasonable (probably it's dangerous) to extend the limit for RTX 2070 (from 115W to 150W). If yes - whch way is it possible? (write modified VBIOS or some easier way)

Thank you!

 

Programmer and a modded vBios or shunt mod. However, as Meaker pointed out, the weaker vrm on the 2070 might not be too happy about increased power limit.

 

It's out of the shipping spec, as for how dangerous you would look at the vrm and see how you are pushing it.

 

Hello,

Is there the easiest way to configure LCD hinges and make a lit bit easy to open display?

Thanks.

 

No, but the weight of the base should make one handed operation easy.

 

In my situation, I can't make it by one hand. LCD hinges are too tight.
Is there any instruction how I can configure it?

 

You would need to open the top casing and mechanically modify it. This would void any warranty.

 

Guys, what do you think about M.2 NVMe SSD in our laptops? Heat, temperatures ?? (temperature of SSD, Bridge\PCH)

Currently thinking about "Samsung evo 970 plus 1Tb" or "MP510 960 Gb"

 

If you're installing an NVMe SSD, I would recommend an M.2 heatsink and installing the SSD in the M.2 slot below the GPU fan as that one gets more airflow. I can't speak for the 970 EVO Plus as I don't have it, but my Sabrent Rocket (Same drive as the MP510 with different firmware and factory overprovision) tops out at about 70C on the controller when benchmarking, while the PCH maxes out around 80C. Keep in mind that it is currently summer here and my ambient temps are usually around 27C.

 

"M.2 slot below the GPU fan as that one gets more airflow" - an airflow in clevo p775tm1-g??? what??

80C for PCH is that ok? (in my laptop as far as i understood some laptop chassis parts thats udner the keyboard palyes cooling role)

(In my location - i have temps like 30-35 C ) )


UPD: You mean this one?? But GPU will heat it up, is it reasonable?? More over airflow done by this fan seems to be directed in other than ssd slot way.

Well.... may be you are right but still not sure )

 

Yes, that is the M.2 slot I am referring to.

 

80c for the PCH is fine.
