XTU. -180mv right now stable daily. You can use other stuff too but I tagged UV to explorer.exe in xtu and call it a day

For shortcut will give it a shot! The more you know~

You create undervolted profile in XTU with explorer.exe process?

 

Yep. I figured why not

Nice. Are you on the 6700HQ or 6820HK? 1060 or 1070?
I'm testing it the 6700HQ at -100mV and temps seem to have dropped significantly.

I thought XTU made changes to the bios so running at startup is not necessary. Is that not the case?

 

She's on 6700hq with 1060

I ordered the P650RPG from Xotic PC and while I love the notebook I'm disappointed with Xotic PC. I've wasted a lot of time on the phone with their customer service and besides being extremely rude over the phone they don't honor their price match guarantee even on their own prices! I ordered the notebook and a week later before it shipped the price drop. Also emailing them is futile they honestly don't check their email as I've never gotten any replies.

Alright enough with the bad how about some good! Temperatures are kept completely in check running the 1060GTX at a 20% overclock peaking at 2Ghz! I was running Xcom 2 at max settings minus multisampling and it was averaging around 60fps. In the BF1 beta it was chewing up the ultra setting and spitting it out at 75 fps rarely dipping down to 60fps. Fan noise was loud and would annoy anyone sitting nearby but hey this is a thin and light gaming laptop it has to spin those fans fast to keep it cool. it's silent and idle and browsing but near 50db at load. CPU temps were 36c idle and around 70 load. Gpu temps were 41c idle and 76 load.

The laptop is thin enough and light enough to sling on my back for travel which I do a lot of. the case is strong but I dislike how much of a fingerprint magnet the back panel is. Mine came with the multi color keyboard which is sweet but the screen does have some backlight bleed on a blank screen which sadly sounds par for the course. Also as a side note the screen only overclocked to 63hz so no point in messing with that. The Sager bios that comes from Xotic PC has zero CPU option which is sad as some thermal performance gains can be had by undervolting the CPU a tad. I have some photo's I've taken but I'm not used to the controls on this forum can someone explain how to attach them?

 

Thanks for the review! Also you can use Intel xtu to tweak the CPU

what's the battery life like? what thermal paste was used on your laptop? there are alot of different reports of temps. some all the way up to 90 load. so i'm interested. thx for the review.

Xotic PC isn't very good. when i was looking for a laptop and checked out their site they keep having delays on different part and different systems. customer service wasn't very responsive either

 

Most people seem to be consistent around 72c on gpu. Keep in mind he was at 76c but that's with overclock. The people getting up in the 90s seem to be the outlier. Maybe a bad paste job or very high ambient temps. Not really sure.

i bought GC-Extreme to be on the safe side. i just wanted to compare what everyone else has. bad paste job seems to be what most think

 

Yea if my temps are bad I'll try either GC extreme or kryonaut. Those seem to be the top 2 atm from what I've been reading. Aside from going liquid metal.

Ive repasted laptops with liquid metal and...ugh... Talk about damage to copper.

Yea not worth the 1-2c diff for the trouble from what I've heard.

It eats at all the metals it doesn't like. Besides direct to die replacing heatspreader TIM its not fun

i read somewhere it also voids the warranty because it scuffs up the cpu and gpu

 

I have to do alchohol runs so gonna be delayed poking around

 

So I got my Clevo P651RP-G today, 1060 with G-Sync (supposedly).
Overall I am quite happy with it, but there are a few problems.

The laptop is very loud under load and the Control Panel doesn't really help.
Overclock mode seems the most quiet, but it's still very loud. The GPU only gets 70 degrees and I wouldn't mind it staying around 80 for less noise, but I can't select this.
The custom mode allows for a fan ON after a certain temperature together with a maximum fan speed, the problem is the maximum fan speed is ALWAYS 80-100%, even if I set it to 60%.
I am on control panel ..73 and BIOS 2.18.1260. I tried checking for a new BIOS but I can't find it on the Clevo website (just drivers there) and the Control Panel also seems up to date.

The second problem I have is G-Sync. At home (I am abroad right now, that is why I bought this laptop) I have an Acer XB270HU 144Hz G-Sync monitor, and with G-Sync the FPS never goes above my refresh rate (it stays at 143-144 if the cap is hit, with G-Sync on).
On my Clevo with G-Sync on (both fullscreen and windowed checked, in Nvidia Control Panel) I noticed the FPS goes way above 60 and I still experience tearing. This is not how I am used to G-Sync, looks like it doesn't work at all?

So the G-Sync issue is pretty weird (it even says the screen is G-Sync capable in the drivers and the G-Sync tab is there) and the noise is annoying, but with headphones it's OK and I could still re-paste. But I hope there will be a BIOS/Control Center update for better fan control, any news on this?

The speed on this machine is very good though, can easily run BF1 on Ultra and the colours on the screen are good.

 

As for gsync, did you double check that the GPU isn't set to mshybrid in bios?

Sent from my SM-G935T using Tapatalk

 

It is set to Discrete (BIOS & Control Center), the LED for Discrete is on as well.
Most of the Nvidia control panel is also inaccessible when it is set to hybrid.

 

Gotcha. That's weird then. I always thought gsync was supposed to limit you to your framerate. My only other idea is if you have something like fast sync on, maybe it uncaps. I don't know too much about gsync though.

 

No no, this means you have your desktop monitor set to VSync on. GSync is only on lower than 144fps. from 30-143 its on, when it hits the monitor refresh rate it either turns off or turns on Vsync. You just need to turn on vsync.

You definitely aren't supposed to use liquid ultra with anything aluminum, only certain metals or yeah itll react.

 

Looks like you're right, I don't remember setting it up like that at home but I might've done it that way.
I think because my desktop runs at 1440p 144Hz, something not a whole lot of games reach (even with a 980TI) I just notice it much less often (in games like CS:GO I cap the fps at 140 anyway to reduce possible input lag).
A 1060 at 1080p is bound to go over the cap, I can actually set most games to ultra and just not look at the detailed options, it runs well anyway (which is great).
Now with G-Sync ON, V-Sync ON and the FPS capped at 58 in Nvidia Inspector it works like a charm, no or not a lot of input lag and no tearing.

 

You can leave VSync off and just cap the fps at 56-58ish and it should have GSync always on, that's what I do in shooters now to keep gsync on without the input lag of vsync.

 

Sounds like there's a significant difference in fan noise between the P650rp and P670rp models this gen.

A lot of people mentioning how loud their P650rp's are. So much so that I've ruled them out for my needs now.

 

Keep in mind the p650rp6 has 1 less heat pipe and is thinner. This may be the reason why.

How do just cap the fps??

 

I haven't tested the battery life yet since I haven't taken it in a road trip yet. It has the ICD7 paste. Also id like to note that underclocking my 1060 below spec values resulted in zero difference in temps so when I'm plugged in I let the overclock rip! If I'm gaming on battery I'll run under clocked at 1500Mhz because it's the sweet spot in a lot of reviews of the 1060 when performance per watt is converned.

 

Depends, some games have it built in like Black Ops 3, but I think there are third party applications that can do it.

 

So external monitor is ONLY with dgpu?
I spend a lot of time hooked up to a 24" display at home and want to often use just the Intel gpu.
I can't believe this is not possible?

 

The discrete GPU is wired directly.to all of the external ports so no you cannot use the igpu when connected to an external monitor. This is mostly for VR headsets which require the dgpu powering the output. If I may ask, if you are home and hooked up to an external monitor why not use the discrete GPU? I would assume you can remain plugged in.

Thanks for the reply.
Guess gsync is priority now. Doh!
I've never used it.
Dgpu for games, Igpu for everything else.
Extends lifeyime of dgpu.
4 years is my upgrade cycle. Ha
Plus, Quick Sync with Igpu for some video editing.
Wanting a 1070 and 17" sager, my p170em with 675m from Xotic getting long in the tooth.
Maybe I'll wait for Kaby Lake, bios fixes, and an Igpu diplay port ha

 

Thanks for the tip folks to use XTU to bring down my cpu voltage a bit. I ended up at -185mV and could run prime95 with max turbo and no throttling at 70c. I tried running it without the offset and my temps jumped to 80c and started throttling as it was showing 20 watts higher TDP! I was trying to attach the profile to a program in XTU because I want to run that profile all the time but unless you have program on screen it won't register in XTU so I guess I'll just have to load up XTU everytime I boot up for now

 

Wow that's a huge drop in tdp and thermals! I'll be doing this first thing when mine shows up! It's not possible to push the clocks any higher is it? I read on past locked CPUs it was possible to get another .2ghz or so via raising the multiplier a little because of something called over clock bins.

 

Hey guys, i have a question some people with their 17 inch have an extra heat pipe connecting the gpu and the cpu, does the 15 inch also have the extra heat pipee? It would be great if anybody have a picture of it.

 

The 15 inch p650rp6 with the 1060 doesn't. The 15 inch p650rs with 1070 does.

there seemed to be an option to adjust the multiplier in XTU so I'll let you have some fun with that when your PC arrives! In the mail yet??

 

Sadly not yet though it's a holiday weekend so business doesn't start up until tomorrow again. I'm hoping for tomorrow.

Is it a big help in terms of cooling with the extra heat pipe?

 

ObsidianPC, a reseller, tested both the rs and rp6 and said that the CPU on the rs(with extra heat pipe) took a good bit longer to hit its max temps versus the rp6. So it seems to help.

 

I see that some people lower their tdp to decrease the temps on the cpu, its not going to affect the performance much right? Im a nubie in terms of lowering tdp etc.

 

I made a clip of an xcom 2 mission play thru to give anyone interested in the thermal/frequencies/fps behavior during a real world gameplay session. I'm sorry about the overlay being hard to read at times I should have moved it to a different corner.

 

They are lowering their tdp by undervolting the CPU. This doesn't reduce performance. In fact it actually increases CPU longevity by pushing less voltage through it all the time. In turn this reduces thermals, and increases battery life. It's basically a free cooling and battery upgrade.

Thanks for the video! It all looked great, especially considering XCOM 2 isn't exactly renowned for its performance. Those boost clocks on the GPU are nice. And the CPU seemed to hover around 50c most of the time.

 

Is there a simple program for nubie to undervolt? And also is it possible to overclock the 1070mobile to match the desktop ones? Thx so much for ur help.

 

Intel xtu is what most people use. It's relatively easy but I suggest looking up a guide or tutorial. Yes the 1070 can be over clocked . I believe it only needs a small 50mv overclock to be on par with the desktop versions clock speed. Keep in mind though the laptop version actually has more cores, so assuming it could maintain that speed it theoretically would be faster.

Aha, thought one was for GPU and one for CPU. In the package with P670 and 1060 there was a small pad and a large pad. In the P651 with 1070 there were 2 large pads.

I have tried some undervolting now to see how that works out. I have tested 100, 120 and 150. The 6700HQ undervolts like a champ No throttling. Emissions is down aswell. When cpu passes 70C it seems fan-noise increase, but with 150 undervolt it never reaches 70C

XTU-stresstest, max temp on core package:
regular voltage offset: 64C
-100: 60C
-120: 58C
-150: 56C
Fallout 4 2 hours non stop playing:
regular: 73C
-100: 70C
-150: 67C

I have not tried anything below -150, but will tonight I had a i5 4210m in my last laptop and max stable undervolt there was 80. I see that standard voltage on 6700HQ is 1.100-1.200, drops down to very consistent 0,980 with -150. My 4210m had 0.950 as regular, 870 with undervolt. It only got 2-3C colder.

 

What are your unigine heaven extreme score? Was wondering what the increase chassis-size does to the use of boost on the 1070. Have you gotten the smartcharge to work? It sometimes work, but it usually chrges to 100C no matter what, bad for battery longevity

 

Awesome! Ty for sharing the results of all the different undervolt steps you did and temps! Seems like it's super effective in reducing temps! Just the comparison I was looking for.

I will try later when I get back from work Xileforce I`ve read that there can be som individual differences between CPUs as to what level you can undervolt them. I see that som get up to -185 in undervolt, which must mean their CPU is of superb quality. I will try that aswell, even though I`m quite satisfied with -150 Have any of you any experience if the XTU-stresstest is enough to test stability? I hate to lose my progress in Fallout 4 when playing Not to good at quicksaving I guess.

 

What have you used to undervolt the CPU? If it is a program with an interface would you mind taking a screenshot of your setup?
My P651 with 6700hq gets quite noisy so I would like to take a look at undervolting.
