Well, ended up calling them and had to pay a little extra. Nice and pleasant experience so far.

 

What laptop config did you end up with?

 

They upgraded the CPU to a 9400F from the 8400 for free (of course, no igpu or optimus afaik).
So the config now looks like this:
i5 9400F
16GB DDR4 2400MHz (might swap these out later)
RTX2070
144Hz Gsync display (was 60Hz with no gsync - they swapped out the panel after I paid a little extra( not the total 200Eur you would get).
1Tb Hdd - have a 2tb ssd back home which ill put in.

 

If you end up swapping your ram, the sweetpoint for price to performance is around 3000mhz.
Your cpu's imc and motherboard will play a part in how far you can push your ram, a better cpu usually has a stronger imc.

 

I might grab a 9700K later though. Not sure I would get a 9900K and UV it. I like my hardware running cold though .
Offtopic:
Cooling shouldn't be too bad. I do think I'll end up attaching smaller adhesive copper heatsinks as well. Just because I'm paranoid.

 

The desktop systems do not power the IGP, correct.

 

Any idea if it can be enabled to gain switchable graphics at all meaker? I am pretty sure it cannot be done as far as all the reading I did about it earlier lol. Was just wondering

 

the motherboard doesnt have the traces necessary for that afaik. so ud have to do extensive hardmodding to enable it

Right. Oh well, anyway battery isn't the first priority for us guys using clevos. lol

 

Well. Got my hands on this hot piece of kit. Barring a few bits of cosmetic dings, the thing performs according to my expectations.
Had a ridiculous power limit thing going on because of 40A Iccmax limit. Had to bump it to 100 and undervolted the processor by 160mV.
The thermals are good and it doesn't EDP throttle anymore.

Validated the UV with small FFT for 10 minutes just to be sure. Set up TS the way I like it. Apart from the old age inducing boot times thanks to the mechanical drive, I have no other problems.

 

The tweaking begins!

 

Haha Dent, nothing like what you guys are doing! I am just trying to make this machine "mine" so to speak. Once I am happy with the setup, i'll start shooting questions to all you awesome lads out here on the forums with my queries.

 

Current bench results:

UserBenchmarks: Game 97%, Desk 63%, Work 49%
CPU: Intel Core i5-9400F - 84.9%
GPU: Nvidia GeForce RTX 2070 - 117.6%
HDD: HGST Travelstar 7K1000 2.5" 1TB - 30.7%
RAM: Crucial CT8G4SFS824A.M8FE 2x8GB - 80.1%
MBD: Eurocom Sky X4C

HDD seems to be having issues. Trying to figure out what the hell is up. lol

 

Hmm, mechanical drive.

Defrag it.

 

Replace the spinning rust

 

Don't know what's up. Forced the sata under PCH settings to Gen3. Nada. It is a new drive by the way.

That's the plan Meak. I pmed you about something. It is a last resort if I have problems with my approach.

 

Hi guys,
From Yesterday my pc running at 0,79ghz...both through battery and AC ...did not anything and it's not a temperature problem...

 

Did you check how much voltage and current you're drawing on throttlestop? Any limits showing up in it?

 

Yes a ”classical"-100 through obsidian software but It Is running in this way since manu months without problems

 

No, that's not what I meant. I believe you are talking about the offset voltage which you have used to undervolt. I am talking about total power draw in watts and what core voltages you are seeing.
If we get the following information from throttlestop:
1. Core voltage on load
2. Total package power draw
3. IccMax in FIVR
4. Limits to see what type of throttling is occurring.
We could comment further on what you might be seeing.

 

Hi, this is my situation, I don't know if it is enough (from bios I did not touch anything):

 

Seems like it's in a power saving mode. Why is Turbo Boost Power at 1W?

 

What power profile are you at? CPU VID is half of what it could typically be. You need to be at atleast 1.1 - 1.15V for your core to get to the near ~65W TDP considering you draw around 60A at non turbo clocks. Strange that your VID is that low.

 

Exaclty guys it seems like in power saving mode. Everything is completely fixed in the condition you are seeing. Nothing move. And never happened since, also in battery mode, there always been some variations at the higher values even if is typically conservative.

The point is, in obsidian station, if I switch profile between "silent", "normal" , "maximum", after one second it always comes back to "battery" profile even if I'm connected to AC power and it does not keep any change I do in the "battery" profile...
I really can't understand....

 

Can you try uninstalling the obsidian software and check again?

 

Did it. Incredibly nothing changed. It seems like it is a 790mhz PC @ 0,67v....
I can't really understand what's happening...

 

Load bios defaults and see if it solves it.

 

Did it bios defaults too. Nothing again.
I need my cpu comes back again, Ligtroom is unuseful at 800mhz and I have a big amount of photoso to postproduce..

 

Is there an XTU service running even though you uninstalled XTU/CCC/Obsidian software? If there is disable it, reboot and try loading setup defaults again.

 

No xtu service present. In any case it is suppressed by the presence of the flag "bypass xtu service" in obsidian control center.

 

That's very peculiar. How does it behave if no battery is connected?

 

Just tried: battery removed and only AC adapter.
Again, nothing !
Going crazy

 

Please download ThrottleStop, run it and show all windows as screenshots. And what Windows Power plan? Remember don’t run any XTU services(if then disable in Services). You can also disable most software, services etc (temporarily) with Autoruns.exe.

 

Hi guys,
first thank again everyone for your support.

In some way I now solved but I really can't understand what's happened.

I discovered Intel XTU was just installed. Keep in mind Obsidian Control has flagged "stop xtu services" in its tuning settings. Keep also in mind that, trough intel XTU I'm able to set my RAM multiplier to 1,33 to reach the goal to run them at 2666, that is what my Rpjaws are supposed to run. Without it they would run lower.

I run again Intel XTU and now it worked. Today in the afternoon, even if I tried to run it, it did not run. And I discovered in yellow at the right bottom the "Power limit throttling" reported "yes".
So I enabled "Turbo boost short power ma enable" and immediately I brought to unlimited both "turbo boost short power max" and "turbo boost power max"....The point is I never touched these settings....

What do you think about it?

ciao!!




What is just missing is one last step. Basically now it's not "blocked" to 800mhz anymore but it does not go over 3,2ghz..infact my superPI test is 11" instead of my typically 8"3....

What am I missing?

I answer myself now, just noticed xtu disable "turbo " tecnology...but it did by itself...I never touched it....
mmmmm I'm really confused...

 

Great it worked out for you.

XTU is a crappy tool (you can’t always trust on it once it’s installed). Bro @Mr. Fox can confirm this as well.

You’re sure you can’t put wanted ram settings in bios?

 

Yes, indeed. Caca maloliente.

 

1. uninstall XTU
2. install throttlestop

Configure it to defaults and begin adjusting from there. Most of us here atleast know a bit about it so we can definitely help

 

XTU does try and put the kids gloves on occasionally and that can get in the way.

 

Is the windows power plan on balanced?

 

Balanced, typical windows default

 

Try putting it on high performance. The power profile has a preset bunch of multipliers which do affect scaling I believe.

 

It also impacts clocking behaviour and if one profile gets changed it wont impact the others.

 

Oh well, here is a weird problem I am facing:
Windows BSODs with Machine_Check_Exception after a bit of non-stressful activity.
After the BSOD reboot, the RGB controller/Keyboard backlight stops working.
Programs running when it happens: Chrome/Clevo CC 2.0
Drivers: Running the latest drivers for everything. Also, I had a -140mV uv on throttlestop but I stress tested around -160mV on mine with 20 minutes of P95 small FFT. Weird.

 

-140mv is quite high and applies to idle voltages too, you may either have a bug in CCC or you are hitting the voltage floor at idle.

 

Hey Meak. You are mostly right. I have a -100mV offset in the bios alongwith a -160mV offset in TS. Not sure if both stack up

 

No, they override.

 

That was my assumption as it is a singular variable. i think i'll settle for a 110-120mV UV for calling it a day.

 

Give it a go, if it's ok at that then it would have been the cause.

 

That was it. It ran stable after I put it at around 120mV. On my bga laptop, it would cause a WHEA_Unrecoverable_Error when my uv would be too much. It is my first time seeing that BSOD with the Machine Check Exception.

 

It can vary depending on which the weakest transistor is.
