Deep learning. It doesn't require much out of the CPU when the GPU is running.

 

Isn't it terrible at that? FP16 throughput on GP104 is 1/64 of FP32.

 

Not sure about the details as I'm not an expert by any means, but the 1080Ti is generally the way to go when taking price into consideration, and of course the 1080 is the next best option.

 

GP102 is the same super neutered 1:64 FP16 rate as GP104. So I'm assuming you're using FP32 otherwise you'd experience a massive slowdown if you switched to FP16. FP16 is completely useless on anything but GP100 since Nvidia gimped it on their non-compute cards, it's just there for compatibility. A Quadro GP100 or Tesla P100 would be much faster with its full rate 2:1 FP16.

 

I've tested it (P775DM3 unified heatsink on P775TM). In games that do not make much use of CPU, unified heatsink does the job and GPU temps are cooler. But in any other situations (games are increasingly using many cores of CPU) with unified heatsink I had higher temps both on CPU and GPU, in my case e.g. Witcher 3 in towns, Rust, Hellblade. If someone do only CPU jobs in work or school, unified heatsink will help too, GPU side will help a bit to cool CPU.

In my case separate heatsink is doing better. If Someone would like to swap to unified heatsink I can sell it. New is about 65$ on ebay. Mine is also new (used once for testing) but I can sell for a lower price+shipping.

 

It is a lot more easy to control temps, set clocks / undervolts, with independent coolers...
Shared coolers will only have an advantage when you have high load on just one device, either CPU or GPU.
For CPU only intensive tasks i would go with shared cooler.
For GPU only intensive tasks i would go with shared cooler.
For High Load on both GPU and CPU i would go with independent coolers. - Nowadays games would fit this description...

 

The question is... Will Unified heatsink work ok with the less powerful 1070 + 8700K in high load on both. This for a user that use his machine for both Gaming and run lots of Cpu only tasks. With 1080 of course this will be another matter if Gaming is half the fun.

 

That is exactly my conundrum. I know I want to eventually run demanding games on a P870. But, in the lead up to that point, I may need to get a system that bridges where I am now. Cost-wise, P750 and P775 start converging with the P870. Would make no sense to spend that much on a machine that has to be performance-shackled because of thermals. Rather just jump straight to the juicy center.

Yeap.
I would say that 1060/1070 with unified works better. I'm actually spending a lot of time adding Unified Logic to my fan control so that it can balance loads when a unified cooler is present.

The 1080 and 8700K is the problem, it's already too close to the limit. The fact is that this combo with unified cooling was very hard to tune, getting the right UV and mandatory clock down for 100% Loads on both CPU and GPU. The independent coolers makes it a bit better to tune, you can tune the CPU without having to worry on how it will affect the GPU and vice versa.

For Single GPU the P7 is the way to go, I see no reason to go for the P8 unless you get your hands on the vapor chamber which is not included on single GPU P8.

Maybe in the future Clevo starts adopting Vapor like solutions on P7 level systems... Now that would be a killer.

Thanks.

From what I have seen the bigger P870 Cpu heatsink will do a better job cooling an nice oc’d Coffee lake chips. I talk about single heatsink setup.

 

Is it safe to change power limit 1 time window to 128?

 

Time window is irrelevant and I don't even know if it even does anything. I think it's supposed to be the amount of time that a system is supposed to be either:
1) exceeding the power limit before the PL flag gets triggered
2) the amount of time after the power limit gets triggered that you need to be back at normal TDP before the flag gets reset again

Intel's documentation looks like a rocket science paper in trying to explain this.

 

It's for when the CPU exceeds PL1, how long it can run at PL2 before PL1 kicks in. IME the actual time limit is double what you set, for example setting 28s makes it 56s. Though usually there's no reason to change the time limit if you can just increase PL1.

 

I see, bah i still can't keep 4.7GHz bellow 85C. My new CPU doesn't undervolt as much as my first one

 

Just recently bought a Clevo P775TM1. How can I get the prema bios for it? Any help much appreciated! Thanks

 

You can't if you didn't buy from a seller that offers it as stock

 

I'm guessing in going to go down to 4.5GHz and find some good undervolt

 

oops sorry for previous post

 

Can anyone help me?

in 2 days, I have a very long flight to USA (about 14 hours).

Since airplanes AC outlet only support 75watt, Is there anyway that I can force my laptop to use only under 70watt. (I don't mind if it works worse than Pentium 3)

As you know. The power adapter uses 330watt.

sorry for my Egnlish. the main reason to come to USA is to learn English

 

I have had one of these since January and while gaming today it just turned off. It was not hot and there was no warning, it just turned off. I have let it sit for about an hour and I can see that it is fully charged up but it won't turn back on when I press the power button. Strangely when I unplug and plug it back in again I can see the battery charging indicator and the plugged in indicator are lit but as soon as I press the power button both lights go off.

Any suggestions on what I can do before calling the company tomorrow to have it repaired?

Thank you

 

What country were you coming from? What nationality are you?
And please quote other people in your replies. In your last reply above, we have no idea who you were talking to or what you were talking about, as we can't see who you were replying to.

 

Sounds like a dead CPU, happened to me aswell.

 

It needs to go back to the reseller for repair.

 

I sent the laptop back to the manufacturer. Hopefully the shipping company does not destroy it on the way and it gets repaired quickly so I can go back to using it. Using my old laptop feels painful at this point since the new one is so dang fast.

 

The AC outlets in aircraft are designed to trip very quickly with excessive load.
Large laptop power supplies use large capacitors that draw a large surge current. The aircraft AC power will trip before the power supply even gets a chance to start up.
As far as reducing laptop current, You could use xtu to set the maximum cpu wattage.

 

Put windows into power saving mode and set the nvidia control panel for maximum battery life.

 

I mean no offence but why? If you can afford this laptop surely you can afford a Surface device or an iPad which far exceeds your minimum Pentium 3-like performance right? Also be mindful lugging a cumbersome "desktop replacement" beast like this via security checkpoints. No offence either to my US friends here but your TSA agents can be "unwelcoming" to visitors.

 

Depends how much you intend to use the secondary device I suppose. I've been through American security with both the p570wm and while it turned heads it did not give me any trouble with a propped bag.

 

Hi MLer, I'd be interested if you have time to share your thoughts in knowing a little more about your Linux install on this machine - any issues you ran into, command line boot / grub parameters you had to set (modes, ahci, etc. ), any other preinstall issues, any requirement to first skip then later add nvidia drivers if necessary, any drivers that you had to add after the fact and if so if you have a list of where you got them / which ppas you had to add, anything that wasn't working as you expected after your distro was fully installed (and maybe still isn't), etc.

Oh, also, which distro you are using

I've been a Linux users since 1993 and am happy to change UEFI params, rebuild Linux kernels, add modules, sneakernet in modules and manually add them, etc. so I'd be glad of the nitty gritty details as you have opportunity and inclination to post them.

While I plan to keep the Windows on this machine, my purpose is to adjust the partitioning scheme to allow a dual boot, and my plan is to be using it primarly under Linux most of the time. (Any Windows use would mainly be as a media system (audio) not games.) I'm hoping to load an Ubuntu 18.04 LTS derivative install on the machine.

Kind regards

Derek.

 

Read the posts. Pretty self explanatory.

@Joe Benedetto makes his very first post at Notebookreview asking @Phoenix for help tuning his old laptop. Phoenix respectfully explains that he only does it for HIDevolution Gaming Team members.

Joe then goes on a tirade here, on Facebook, and who knows where else, and also blasts us with several similarly hateful emails.

We explained that Phoenix does this OS tuning voluntarily for HIDevolution Gaming Team members, and other than being our customer, has no business relationship with us. He has no obligation to even do his work for HIDevolution Gaming Team members. It is a love gift.

So, since the only way Joe can get Phoenix to volunteer his time to help Joe, is to buy a laptop from HIDevolution, Joe decides the best thing to do is hang curses on our house and never buy anything from HIDevolution...ever! Go figure. I can only assume Joe is not a result oriented person.

 

The mods came in and cleaned house is what happened. But hey, expecting experienced hands on advice for free seems to be the done thing sometimes.

 

Well, to be fair, he did offer to pay Phoenix, but seemed not to realize (or didn't want to believe) that Phoenix doesn't do this for the money. He also apparently can't believe that Phoenix doesn't work for HIDEvolution or that the HIDEvolution "Gaming Team" isn't an official part of HIDEvolution as opposed to just a group of customers. In any event, let's move on.

 

When I did do a mid for someone it was not cheap and they paid for my travel + travel time. It was a physical tweak too. People underestimate the value of time and experience.

Either way yeah, insulting someone is not going to ingratiate someone.

 

I sure hope the RTX 2080 mobile version will work on TM platform, and HID will offer upgrade service too

 

OK So, I took delivery today and am thankful that I managed to answer my own question

UEFI on. Security off.
1.) I created a Kubuntu 18.04 thumb boot drive.
2.) I booted that - no graphics when clicking on the "Run live" option - which I wanted to do 1st to test it
3.) I rebooted with nomodeset in the boot line. No wifi. I'll come back to that below...
4.) That fixed the Run live option and I was able to proceed to the loader. This is an issue I believe with the nvidia driver that I had read about elsewhere on similar gear
5.) In the installer, using manual disk allocation, I resized the NTFS partition down to 250GB (2GB SSD - was taking all of it but I needed most of it for Linux)
6.) Likewise I resized the NTFS partition on the 1TB spinning drive down to 500GB
7.) I then allocated 500MB (too much - spare good to have) for /boot with ext4 and then 1.6TB for / (I don't need other separate partitions) and the rest - about 9, nearly 10, GB for swap
8.) I gave the other 1/2 of the 1TB drive to a backup partition for Linux.
9.) The install proceeded OK. I rebooted with nomodeset and installed the nvidia driver from the proper repo - version 396 working just fine.
10.) I then had to install the wifi driver - needs building from source - according to the following instructions I found at the link below. Worked fine when I'd done that:

sudo apt update
sudo apt install build-essential git

git clone https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
cd backport-iwlwifi
sudo make
sudo make install

sudo -i
echo “options iwlwifi disable_msix=1” >> /etc/modprobe.d/iwlwifi.conf
exit

Link for the above is here:

https://askubuntu.com/questions/1038242/no-wifi-option-on-ubuntu-18-04-and-16-04

OK. So, that's it.

Wifi is working. Nvidia is working. BT is working (although I haven't paired anything yet).

Haven't tested display port, HDMI, etc. under Linux yet. Should work OOtB.

Trackpad is working. Haven't tested the FP reader.

Kind regards

Derek.

 

There is no RTX 20x0 laptop GPU. The RTX series is for desktop GPU’s only.

The next gen laptop GPU will be GTX 11x0, and the release date has not been announced, and the NVIDIA non-disclosure is still in effect. The best guess floating around at this time seems to be that they are not expected to start shipping until early 2019.

 

So no ray tracing love on laptops? Damn.

 

I read the posts and got what happen, was just surprised that's all.


It's a shame that the 20x0 series won't be coming to laptops. The ray tracing stuff looks awesome.

 

It does indeed. But, at a potentially terrible performance hit. These cards potentially have more features corresponding to the larger die size that make them unique. These cards may need to be cut down/stripped in order to fit inside a laptop chassis. I think with larger laptops such as the P870, we can handle at least one card from a TDP perspective. SLI with these cards on a laptop would leave me breathless. I would be corrupted by the dark side - hands down.

 

You could also try disabling Hyper-Threading in the BIOS, essentially turning your 8700K into an 8600K. That'll drop the heat/power by a not insignificant amount and let you keep the overclock higher, and most games don't benefit from HT with 6 cores.

 

Not even the P870TM1 successor? Sad news

 

Most of the games i play and plan on playing do use all 12 threads like BF1 and BFV

 

Metro are aiming for 1080p 60fps for ray tracing.

 

Using 12 threads doesn't necessarily mean Hyper-Threading is benefiting performance though. And if disabling HT gives you thermal headroom to clock the CPU a few hundred MHz higher, you could actually see a performance uptick that way.

Spoiler

But if you're multi-tasking in addition to running the game, HT will definitely be beneficial.

 

Hmmm...i guess ill give it a try, but it's kinda a waste paying for 8700k and not using HT. However, my replacement chip is a worse then my first one requiring more voltage for the same clock. I could undervolt my old one by -110mv while my new one i cant go past - 85mv.

 

Depending on the default voltage, that may or may not make the new one a worse chip.

And yeah I was only speaking in terms of gaming. For multi-tasking and productivity definitely keep HT enabled.

 

How would you check default VID, it fluctuates a lot. And what do you mean by that?

 

Check it under a consistent load, like CPU-Z stress test.

 

Im probably around 1.37v
