Sager NP8454 (Clevo PB51RF-G) early impression

I wonder if Gigabyte is doing the same thing as soldering everything on the mobo

 

My main issue is recovering soldered storage.

 

So it’s ok that everything outside storage is welded on the motherboard? See... Alienware soldered on yesterday’s WiFi card. Who needs today’s or tomorrow’s hardware on newest and most shiny middle 2019 Make it completely then solder on yesterday’s Eternet chips as well. Dell fixed that as well

Would it be equal ok for desktop board also?

 

Hardware can always be replaced is my point, data most often cant.

 

Gentech gave me the money back. Ordered the Aero. Waiting game begins again.

 

Gigabyte Aero 15 OLED? :Shudders @ 4K on 15.6" panel:

 

It's the same panel as the Clevo.

 

I'm getting to photography and video editing so I want to see how I can push the Oled

Funny you say that. I noticed the Aero looks very similar to the Sager I had

 

There are not that many panel manufacturers out there

 

do you know when you'll receive your aero ?

 

I placed my order on the 20th. I did order the repasting and fujipoly pads since they were 1 cent a piece but that's the only customization I asked for.

According to the website it would take 5-10 days to ship if any customization is ordered but I will start bugging them at the end of the week.

 

according aero website they already ship with thermal grizzly not sure how accurate that is

 

I saw that but in the few reviews that Ive seen, the laptop throttles even with the claim of Grizzly. I chose to have kryonaut done to mine.

 

Might want to go over to their section at this point.

 

did you get it yet ? i got mine last week 1660 Ti but the performance is not good wondering how yours is like

 

I got mine. I started a thread http://forum.notebookreview.com/thr...x-q-initial-impressions.829896/#post-10938474

Move over to that thread and post the issues you are having. We can work together and figure out all the problems. I have some snags as well

 

Hi does anybody know how to update the bios on the Clevo PB51RF(using https://download.schenker-tech.de/package/xmg-pro15-xpr15m19/) i have the files, just want to know if you run Bios-XMG_PRO15_17_XPR15M19_XPR17M19_EC_1.07.10TRC1.zip directly and then the Bios-XMG_PRO15_17_XPR15M19_XPR17M19_BIOS_1.07.12RTR2.zip?

 

Did you buy the system from them? Or have you contacted your reseller?

 

Its from a different supplier, but they dont have the bios update v1.07.12 available yet only v1.07.07, so was wondering if i could update my system with the XMG bios?

 

If its a different supplier I wouldnt use it to be on the safe side. Thats a risky move

 

What issue are you having currently wanting to make you update?

 

what's your temps in games/benchmarks at that clock speed? very impressive!

 

Benchmarks will hit 94C on the CPU at that temp (fans maxed out btw). GPU doesn't even hit 60C. I don't run it like that for regular use or gaming because it's simply a waste of energy.
Here's a link to my highest Firestrike score so far: LINK

The reality is for regular gaming, combined with G-Sync and a frame-limiter, I run it at 3.6ghz all-core underclock (full 1ghz lower!). 3.6ghz all-core draws about half as much power at 70W (as opposed to 140W in that 4.6ghz run!) and in games it's more like 30-4W. So it runs much quieter and cooler (~70C). In multi-core workloads, even at 3.6ghz it still walks all over the 9750H.

I'd need to swap paste to get more out of it. It's using ICD (which is stock from Metabox) right now. Kryonaut would buy me a couple of degrees and Conductonaut a few more on top of that. But it's the middle of winter here and I almost never run it that hard in any practical use so I'll probably wait until warmer months to bother with repasting.

 

What voltage offset are you running at 3.6Ghz?

 

I'm curious as to how it's able to sustain 4.6 at 94c? that's all really nice info, thanks for that. I'm contemplating on getting this config, that's why I ask

 

I'm currently on -130mv for 3.6ghz. I could probably drop it some more but since this is primarily a work machine, I don't have a huge amount of time to risk BSODs during the day

First thing, is you MUST lift the rear of the laptop as the air intakes from the bottom. By default, the rubber feat are simply not enough to lift the machine under those kinds of loads. In my case I use a Deepcool Windpal notebook cooler, but I don't even plug it in and use the fans. It simply acts as a stand for increased air flow. Although using the fans would probably help too.

Second thing, is for those runs I am running the fans at 100% using the FN+1 shortcut.

To be clear, running it at 4.6ghz is highly impractical (at least on my stock paste, Liquid Metal is another story). If you intend to render on it or do any longer tasks, running it at something like 4.2ghz all-core is much nicer at ~80C and you don't lose a lot of performance.

 

Your assumption is correct. Update EC first, then BIOS.

A new instruction manual is here:
https://download.schenker-tech.de/package/bios-update-via-efi-shell/

If you are absolutely positive that you have PB51Rx(-G), then it is safe to update our EC/BIOS, even if you bought your machine at a different reseller. If in doubt, check the rating label first.
If you need more support, feel free to send me a PM.

Cheers,

Two bottle caps is the portable solution.

 

huge help in my decision making! I appreciate it. hope everything goes well, now. it's definitely a unique laptop to have and fits my needs almost perfectly (there's always a downside to a laptop, as I see).

 

Every laptop is a set of compromises to fit a specific need case.

 

Question for anybody who has this laptop. What does the HDR support look like? I know that other laptops with this panel do support HDR like the Razer Blade or the Gigabyte Aero 15.

 

My NP8454 didnt even give me an option to enable HDR. I would say it doesnt let you play HDR at all. My gigabyte comes with the option to enable HDR but I set it to play HDR content only on plugged in, to save battery life

 

Hi, would anyone be so kind to report the minimum discharge rate (and cpu package power) reported by hwinfo on battery with optimua enabled and powersaving profile?
Ideally also the lowest Package CState reached by the CPU while on idle

The reviews seem to point at 16W idle consumption which is a bit high

 

It looks like clevo PB50RF with i9-9980hk is only available in Europe with 240hz display (no gsync available here).

PB50RF-G and PB51RF-G have only 9750h with 144hz display.

If i purchase the PB50RF with 240hz display and ask the reseller to swap this display with that 144hz, will g-sync now work even if the original unit with 9980hk didn't have such a feature ?

 

If I had to guess, I think the MUX chip is bypassed in the BIOS on the 240hz versions as it doesn't support enough lanes to drive it. So you would have to get a BIOS flash as well.

 

edit

 

Notebookcheck did a pretty in-depth review of this machine a few days ago.

https://www.notebookcheck.net/Euroc...F-Core-i9-4K-OLED-Laptop-Review.431869.0.html

 

Officially the bios you could get would disable it still

What's amazing is that Passmark ratings include every laptop of any kind, with any CPU/GPU or display. Sager really stands out here with a 4K display on an i7-9750H CPU.



I simply can't emphasize enough what an absolute delight this machine is. I've been having a ball with it, and I couldn't recommend any system more highly.

HWBOT

And now, I'm off for my next journey. Right now, I'm listed as top points setter for rookies on HWBOT, the site for benchmarking pros. From now on, I'll be updating my progress in other posts...

Have Fun!

Please note that I was originally running with an undervolt of -250mv for the CPU, but Meaker has guided me to realize that was just the CPU limiting the real undervolt. It's now 130mv (updated 10/8/19). I run -100mv for the cache on my 9750H. On my system on battery:

Minimum CPU Package Power: 13.33W (sorry before; now cleared Min/Max)
Minimum C0%: 2.4%-2.6%
Typical Idle Package Power: ~13.6W ("Uncore" is about 12.2W)

Here it is on AC, with all cores running at 3990 MHz:

Minimum C0%: 3.5%-3.7% (with Chrome open)
Typical Idle Package Power: ~16.6W

Note that what you really may care about is the system power consumption. This is on a fully-equipped system, not a stripped one (see the previous post for details).

Typical system power consumption on battery:

Average Idle Power (w/Chrome running): ~25.2W)

With all the goodies I've got in my system, this suggests that I'll have a battery life of about 2:25 just sitting there!

 

That's a large undervolt. Have you double checked it's properly applying by looking at load voltage?

 

Hi, thanks for the info!
The uncore usage looks quite high, at 12W out of 13W...would you happen to know why?

Can you also confirm the lowest package Cstate on battery on powersaving profile is C0? Or does it reach Package C8-C10?

 

Hi, Gang,

I've never attempted this undervolting process before, so I'm just starting to learn. I really don't know why Uncore is so high, other than all the interfaces that the CPU has with dual-bank RAM, etc. Hopefully someone more knowledgeable will chime in.

Regards,
Mark

 

If you go to -175 does that VID go up? If so pop it back down and enjoy

 

Hi, Meaker,

Interesting questions! I'd been relying on ThrottleStop's controls, without paying enough attention to the VID that was displayed. Based on your suggestion, it does look like VID stops going down at an offset of ~~-100mv, even though the control says it's more. Hmm, much to learn!

Sorry!
Mark

 

That's ok, better to really know what's going on. Your temps and performance though are still perfectly valid

 

Hi, Meaker!

I've been updating the benchmarks in that post as I continue to find more ways to improve my scores. The next small step is to go to DDR4 3000 CL16 RAM, but beyond that, I'm excited to go get a Prema BIOS.

Please pass along my sincere thanks to the Sager team for creating such a wonderful machine!

Cheers!
Mark

 

Will do

 

So you mean that PB50RF (with i9-9980hk + 240hz display) and PB51RF-G (with i9-9980hk + 144hz display) may have different bios versions ?

If so, does this mean that clevo is using different motherboards for these 2 model ?

For instance: MOBO_PB50RF(with i9-9980hk) has NO mux (so only optimus mode hence no gsync), while MOBO_PB51RF-G (with i9-9980hk) has mux so both optimus and dgpu mode are available ?

 

The boards are likely to be identical. But the ability to configure the MUX chip is disabled so that you can't accidentally flip modes and end up with no screen.
