*** Official Clevo PB7xEx-G Owner's Lounge***

Good to read! What are the noise levels / decibel readings when actually playing games? Have you tuned fan control?

 

Got My prostar branded pb71ef in on Tuesday and have gotten to play around with it, I am really happy so far. The screen is great with no stuck pixels and no visible light bleed in normal use. I don't plan to stare at black screens in the dark to see it is there since it is invisible in normal use. I replaced the single stick 16gig ram with two 8gig 2400hz stick with a noticeable boost in timespy score. The 2070 takes a OC well without heat issues and I undervolted the cpu by 130. CPU temps when gaming (destiny 2, The division 2) tend to run in the mid 80s, GPU in the low 70s. Max cpu temp i have got is 91 in timespy. Fans are pretty reasonable when running full tilt. Not silent, but not obnoxious.

Division 2 runs 100-140 in maxed settings 1080
Destiny 2 runs low 90s-100s with maxed setting 1080, rendered 115%

My only complaint is the procedure to get the keyboard off to access the ram and HD slots was horrifying as I was afraid I was going to stab a screwdriver through the computer. I honestly might leave the one screw you have to get to under the keyboard out if I open it back up in the future.

My previous computer was a desktop with a 1080 and 4790k. I never ran timespy on it but the scores I saw with the same config show this computer beating my old desktop by around 600 points.

I screwedup the screenshots by accident by the following is roughly my timespy scores

-Single channel ram, undervolted 125 cpu, 150 core 100 mem OC GPU
7506 total
6200 CPU
7821 GPU

Dual change ram, undervolted 130 CPU, 250 core 450 mem OC GPU
7820 tota
6800+ CPU
8000ish GPU

I think the cpugot around 5800-6000 without the undervolt? I forget atm

 

I can take another reading but probably like 10% or 1db lower. I haven’t tuned the fans yet but given how much heat this laptop emits out of the exhaust I’d be afraid to lower the fans too much.

 

Are there instructions provided regarding how to do this? I’m afraid of taking the back panel off lol. I wish I just bought it with dual channel but ultimately I want to put a second ssd in as well. Good to know I should do it all at once. Can you take a screenshot of the 16gb ram stick? I have no idea what to get in terms of a matching one.

 

Hey scarlet the exact model is Goldkey 16 GB DDR4 pc3000 CL 17 (GKE160so102408-3000a)... Would you like to buy my stick? 105 shipped. Should ensure you get the exact right thing.

I made a fast video to show you how to remove the keyboard (dont forget to remove the screw from the hole you push into first...):

 

I bought a PB71EF-G from Sager and received earlier this month. Runs games great but the thermals are easily hitting 98+ on the CPU while playing Farcry 5 for more than a few minutes. I haven't seen anyone post numbers this high so wondering if I'm an outlier. I went with their IC Diamond option for CPU/GPU paste.
https://www.sagernotebook.com/Notebook-NP8371.html

 

I am using ic diamond as well. The 8750 is known to be a hot cpu. I would download throttlestop and undervolt at least 120. I unfortunately don't have far cry 5 so I can't run it for you and let you know what I'm getting on that.

 

That temp sounds high, here's the test of MSI with similar hardware:

The temps don't reach that high in it. Maybe it was a bad paste job by Sager?

 

Thanks! Yeah that sounds great - I'll send you a PM over the weekend.

 

What sustained CPU clocks are you guys seeing during gaming with single thread, 4 thread, etc?

 

I have a few questions about the GPU performance I am seeing.

Based on my understanding of the voltage curve in Afterburner, the maximum frequency should be 1965 mhz and it should hit that at 993mV, after the undervolt that I applied.

From the few minutes that I played Anthem, the max clock speed that was obtained was 1905mHz - and this was not stable, but rather barely seemed to be at that point. The maximum voltage was 975mV.

So my question is essentially, why did the GPU not attempt to pull more than 975mv when afterburner is showing 993mV @ 1965mhz?

Is it because the CPU was bottlenecking the game so there was no reason for the GPU to request more power?

The max GPU temp was 71. I assume this should not cause thermal throttling?

 

What was your frame rate? What reason did GPU-Z give for the performance limit? There is a temperature curve too which impacts clocks as well.

 

I actually just confirmed with GPU-Z that I am getting power throttled. I'm not sure why, I've done no OCing whatsoever. (The green sections in PerfCap reason all say power)

 

This is my afterburner settings

Edit: after doing more research I'm even more confused.

notebookCheck lists this information for the card:

1215 - 1440 (Boost) MHz

So where is afterburner getting that curve from? Presumably this laptop should not be running 1900 mhz...

Edit 2: It looks like this is potentially related to Nvidia 'GPU Boost'? So I guess every GPU that boosts is going to eventually hit power limit, so in that case what I am seeing is normal?

https://www.geforce.com/hardware/technology/gpu-boost/technology

 

Yes, GPU boost depends on power and temperature, so you might see higher than normal clocks if it has not hit power limit yet.

 

Can someone go to Device Manager<Monitor<Generic PnP Monitor<Properties<Events, then look at the Information box where it says Device DISPLAY\"xxxxxxx"\ and post that please? So we know which display it has.

 

AUO409D

 

That's why overclocking gives less than it used to, the chip kind of does it for you within limits.

 

Thanks, my next question was going to be what is the point of overclocking if there is GPU Boost.

I've been playing BF (singleplayer/offline) on ultra for a while, CPU max was 84 and GPU barely hits 70. I currently have a -.137 voltage offset on CPU, and I am still playing around with afterburner but I've undervolted the GPU to 900 mV. The GPU clock speeds in game generally stay between 1600 and 1800, with the power limit being the bottleneck. FPS stays above 100, but again, this is offline mode just to play around with my gpu/cpu

The thermals on this thing are really great. Also if you minimize whatever game you're playing, or if there is a loading screen or whatever, temperatures drop 20 degrees in like 3 seconds lol

 

You can still force the GPU to go over max stated boost clock with overclocking provided that it does not hit power limit ;-) Plus GPU Boost doesn't really boost video RAM, you can often manually overclock the video RAM by a large amount, though not many games will benefit from that (the only time I saw big benefit from overclocking video RAM was when running ETH crypto miner, but that is not a game and should never be run on laptop ;-)

 

I’m at power limit on my gpu like 90% of the time; I don’t believe overclocking above gpu boost would get me anything.

Will boosting the memory cause more of a power draw? If so would this be a bad thing to do if I’m already at power limit?

 

Yes, overclocking video RAM will increase power consumption but it won't be as significant as overclocking GPU.

 

I suspect you will see better numbers overall after running in dual channel mode as it may raise up the power cap a little.

 

Be sure to check that your XMP profile is enabled in the bios after matching your 2nd stick of memory if you have not already done so.

 

B.t.w, @scarletfever if you're curious about theoretical performance increase with overclocked 2070 GPU, here's a review of Asus model with similar hardware:
https://www.ultrabookreview.com/25079-asus-gl504gw-scar-review/
They run benchmarks with 2 settings: one with stock clocks and one "Tweaked" with +180 MHz GPU clock speed and +300 MHz video RAM. They did not change CPU voltage because their sample could not take it. They also show the performance difference of this hardware configuration when using dual channel RAM configuration.

 

Does anyone with this clevo model have Far Cry 5 and are able to validate whether my 8750H heat readings are typical or unique to my unit? Even undervolting 120mv is resulting in temps between 92 and 99 on all six cores. That being said, this is the only game I've played so far that has been hitting these temperatures so I don't want to reach a hasty conclusion and go down the road servicing/returning/repasting a new, expensive laptop that I'm otherwise happy with.

Thanks in advance to any help!

 

GPU boost is designed around all chips that meet nvidia's minimum requirements, you can tune to your specific chip with overclocking.

 

Curious how low people are able to undervolt the GPU? I was down to 950mV last night without any voltage limits. Going to try lower tonight.

 

You undervolt the GPU by overclocking it.

 

Yeah, but I’m flattening the curve at my target voltage. I guess that’s not really necessary?

 

If you do that without overclocking first, you’re just underclocking the card. Since you’re so power limited @ 115W 2070, I wouldn’t worry about flattening the curve. Just overclock if you want more performance, since all that’s doing is undervolting the card so it boosts higher within the same TDP envelope. Which also means there is no heat increase from OC, you’re simply making the GPU more efficient.

 

Trying to wrap my head around this, lol. Won’t i be hitting power limit at a higher voltage, thus increasing the heat?

 

It won’t exceed 115W (minus whatever the VRAM and VRM consume) of heat anyway. If you simply lock the GPU to a lower voltage/frequency point, sure it might not hit the power limit anymore, but then you’ve effectively just underclocked or Max-Q ified it. These GPUs are designed to boost as high as possible within their power and temperature limits. By overclocking the GPU, you’re optimizing the frequency at each voltage point. Just as a hypothetical example, where you might’ve previously hit the power limit at 1771MHz and 925mV under full load, after overclocking you become power limited at 1860MHz and 912mV instead.

 

It's getting all the limits to line up for your chip at its sweet spot with a stock card/vbios.

 

I've watched several reviews for RTX laptops and performance gains from OCíng GPU is very minimal (1-2%) in real life situations (games). On the other hand, performance gain with dual channel RAM is huge.
Undervolting CPU will bring added performance at lower or equal temps, the same goes with RTX cards but without real performance gains.

 

It will keep the clock more consistent so low frame times will likely benefit.

 

So the low 1% FPS will be higher? That would be a benefit.

 

Exactly when the gpu is most stressed.

 

Is this RAM compatible?
https://www.newegg.ca/Product/Produ...ptop&cm_re=3000_laptop-_-20-232-309-_-Product

 

Probably, you are going beyond Intel spec but it usually works. Might need a bit of tweaking sometimes.

Anyone want to upload the 2070 max p vbios to thr database?

 

Is anyone getting performance close to this? I’m like 20fps lower and I don’t believe I’m therma throttling. GPU is near 100% usage.

 

Are you still running single channel RAM?
If you are that’s the performance difference dual channel RAM has.

 

Wow, that's crazy. Actually yes, it should be here early this week. Very excited for it in that case.

 

Yes, difference between single channel and dual channel can be around 40% depending on games. You can see this in Dell G7 video at OWNorDisown YT channel, he tests this in multiple games. I'm surprised that Sager even sells the "gaming" versions with a single 16GB stick instead of using 8+8 GB by default.

 

I wish I had the setup to do a professional review on this machine because I honestly think it’s the best gaming laptop you can get under 2k. The only comparable machine is the y740 if you can get the 2080mq with a discount.

 

That is great to hear! I've been researching RTX laptops since they launched and the Clevo PB7xEx-G barebones case looks incredible. I can't believe none of the professional reviewers have taken the time to do an in-depth review of this laptop.

I have a few questions that I'd be grateful if a Clevo PB71EF-G owner could answer for me.

First, what is the actual weight? Everywhere I look online I see "6.5 lbs. with Battery Pack". What does this mean? Is this the weight of the laptop PLUS the 230W AC Adapter? Or is it the weight of just the laptop with the 62WH battery installed inside of it? If 6.5 lbs is just the laptop, then how much does the 230W AC Adapter weigh?

Second, what does the inside of the case look like? Are RAM and storage easily upgradable, or do you have to flip the whole motherboard over like on some other laptops? Also, would it be possible to install a larger (94WH?) battery to take the place of the 2.5" drive bay? This is possible on the Tongfang GK7CP7S, where you can upgrade the 3-cell battery for a 4-cell battery by sacrificing the 2.5" drive bay. I'm just wondering if something similar would be possible on this Clevo case.

Third, how exactly does the Switchable GPU by Microsoft Hybrid Graphics work? Do you have to make the change in the BIOS menu when the laptop starts up? Or is it simply an option that you can easily switch in Windows right before you decide to play a game? Or is it a physical button on the machine? Also, what impact does this have on battery life? Would you get double the time running on the Intel HD 630 graphics? 50% more? 25% more? Less?

Thanks for any help you can provide!

 

Are the dimensions the same for all three gpu variants? I remember vaguely that the p650/670 were a but slimmer with the gtx 1060 gpu.

 

If you YouTube the pb51ef-g, there is one review and you can skip to around 16 minutes to see how the case comes off. You need to get the keyboard off in order to access the ram and ssd.

I had to disable hybrid mode in the bios in order to enable gsync. So I guess the nvidia card is just always in charge of the monitor.

 

Exactly you switch modes depending on optimus or G-sync being desired. The two are mutually exclusive.
