Investigating 6820HK performance and overclock!

I will run D2's test later.

I repasted with liquid metal and temps have been nothing short of amazing. Holding 4GHz steady at 65-70w on OCCT, no throttling observed during 30 min test.

Will come back later when I run it for at least 2 hr.




6820HK isn't bad, it's a very good chip and we've come a long way from having 1000$ mobile overclockable CPU like the XM/MX to one that's under 400 usd such as this HK (listed on intel ARK).

It's not as good compared to a desktop 6700K, but it's good enough for gaming and editing task. Users with real power needs should opt for a 6700K if they feel the 6820HK is not strong enough.

What really irks me is the pricing point of these HK laptops, basically marketed as a true DTR and having skyhigh prices, most of the time surpassing Clevo and comparable desktop builds.

I really wont mind owning a HK cpu laptop, but my wallet and common sense says otherwise.

 

Well said and quite frankly it's the truth.

Opinions won't change the facts in that the tides have shifted greatly due to the release of Pascal; and the surfacing of the mobile chips like the 6820HK that can hold its own for virtually all games to date.

Purely on the gaming front taking a 6820HK/1080 vs a 6700K/1080 will be a battle of equal weights (yes I've said it haters) due to the fact that most games don't even tax the CPU much, if at all! Of course some games do utilize the CPU, however, for the most part...most games would never tax the CPU enough to where it would even matter.

The 6820HK as we've demonstrated is a worthy mobile chip that hold its own, respectively, in the gaming arena. The only time the 6700K would really shine past the 6820HK are in CPU intensive work load tasks. We all know this, duh, yet some people just don't get it nor understand that we are talking about a mobile chip vs a desktop chip here. However, we're talking about gaming here and with gaming laptops right?

Although I do not wish for bga to continue in high end gaming laptops as I love socketed chips, delidding and all that jazz, over being fed what I'm given, the main determining factor of ones tolerance for bga is purely based on cost/value to performance ratio and practicality. (Some people sit at home and troll forums all day on their DTR, some people make a living with their laptop and may need extreme portability, etc...)

As of now, the newest kids on the block like the MSI, ASUS and alike that have rolled out their Pascal gaming machines are unfortunately still bga (as expected) with very high price tags. This obviously makes it a no brainer in that if the price is dancing in the DTR category, well...we know what the wise choice would be if you're looking for a portable gaming laptop with desktop components. (But, with Pascal, in terms of power a lot has changed...)

I, along with many of you would personally not pay DTR prices for a bga machine. Now under what circumstances would that change? - There could be many variables, but I'll save that for another conversation.

It's a double edged sword right now at this present time for both DTR and bga machines.

On one end, DTR's are dealing with heat issues along with screen issues in trying to figure out what, when, why, and where of the 5ms / 120Hz panels, where as...

On the BGA end, the prices are just ridiculous for their flagship offerings that knock at the door at DTR pricing. (Likely due to Pascal, but that's no excuse to over charge.)

Now having something socketed is pretty priceless, however, there is a scenario where something like a BGA CPU with a MXM GPU could be tolerable. In fact, there are scenarios where both bga CPU and GPU can be tolerable under the right circumstances, BUT! we don't want to be supporting the proprietary communist movement now do we?

Double edged sword.

Another thing to keep in mind, aside to the silicon lottery, is how often you've really burned out a CPU under even extreme gaming, heavy CPU load etc...Come on...like really...under extreme cases of reasonable usage (including but not limited to, extreme rendering, gaming, CPU Max type of tasks) have you ever burned out a CPU?

This leads to the point of having a bga CPU being the lesser of two evils compared to the bga GPU. At least IMO.

Very interesting times right now in the portable gaming realm...it's all relative to how the tides shift from price, value, warranty, upgradability, practicality, usage habits etc...

Simply put, "Say NO to BGA's being sold at DTR prices." & "Say YES to common sense to make sense of practicality."

Double edged sword.

Gosh okay I was going to just end it there, but I'll just say it.

"With the release of Pascal, the gap between DTR's and Gaming / Power Laptops have narrowed to a point where the DTR's will get a run for their money, no doubt, in the coming months through benchmarks etc... This in turn will cause a huge ruckus among the DTR community, because the throne in which was held before of having a desktop 980 walking circles around the 9XXM mobile series is no longer something that is valid now due to the Pascal chips being shared across all platforms.

Therefore, with the leverage no longer there...things are going to be very interesting like we've never seen it before. It's about to get steaming as ego's will be undeniably stripped with the bga machines right along side the dtr's waving their hands, neck to neck in almost all normal circumstances, less CPU ultra extreme tasks that makes up very little of the gamers in whole. - PLUS, to any normal person, computer savvy or not, don't you find it strange that a DTR isn't being compared to a Desktop or heck even another DTR, rather it's being compared to a Mobile Gaming Laptop with a Mobile chip?

I am still trying to figure out how one gets the jingles out of doing that?" Anyways...

Cheers to pushing things to the Max and having fun while doing it.

"Say NO to BGA's being sold at DTR prices." & "Say YES to common sense to make sense of practicality and for pete's sake stop comparing mobile chips to desktop chips!"

 

6820HK @ 4.0GHz

2 Hour OCCT Run

Max Temp:
67, 60, 62, 59

 

4.1 running stable, will post how to unlock power limit tomorrow


ambient 22c, cooling system on this thing is good, but have weird temp/tdp spikes
@johnksss - any idea on what may be causing that spike?

 

So the bios has been unlocked with the help of my man and yours....@Prema-san.

 

Details please, step by step?

 

+1

 

Very nice, almost 6K) And look at those GPU clocks! Did you measure the power draw at load? I wonder if stock 230W can handle such stress.

with the gpu being severely gimped, I'm sure it's fine

 

So your overall impresions of the G752VS w/ 6820HK are decent and performance is comparable to a stock 6700K?

I received one from Amazon and the customer support rep has given me the option to keep it, even at the price of a lower specced 6700HQ model.

Now I'm trying to figure out whether I should keep the Asus or buy a P775DM3 w/ 6700K at a higher price but with the chance of being able to upgrade it to Kaby Lake/Volta in the future.
Looking at how the Pascal MXM modules aren't compatible with Maxwell Clevos, I don't rate the chances of being able to upgrade too high.

So if the i7-6820HK @ 4 Ghz in the G752 runs cooler than a stock 6700K in the P775DM3, I'd probably just keep the Asus because I'm even saving some money.

I'm not a very hardcore gamer, just looking for a gaming notebook/DTR that lasts me a few years like my old G73JH which I was very happy with. What would you do? Maybe even wait for the G753, any thoughts would be welcome?

 

So far, nothing over 189W from the wall. Measured with my 900W UPS Cypberpower backup

 

Ok, so here is what out of the box is looking...
Stock
1.4V cpu
1.4 cache
28X cpu
28x cache
Everything set to static.



Voltage lowered to 1.1V


1.1V @ 3.8 ghz

 

It's comparable to a stock 6700K with much work done on the system (as you have seen), but the voltage WILL be much higher than a stock 6700K is capable of, and then the 6700K can be easily and reliably overclocked past what a 6820HK will hit reliably (with much difficulty). If you need a mobile machine and don't want a DTR? Then sure, 6820HK with pascal GPUs is my minimum recommendation. If you really want reliable CPU power? Then a DTR is the place to go.

If you're buying a P775DM3 for the cooling and CPU power, then sure. It'll be a better machine than the ASUS (unless you get a really warped heatsink, but I believe the peeps at HIDevolution or Mythlogic wouldn't let that past QC). Kaby Lake as long as it's using the same socket as Skylake will be usable, even if a Prema mod is required. Since it's using the desktop chipset and not the garbage mobile chipsets that couldn't even upgrade from Sandy Bridge to Ivy Bridge without needing a refreshed motherboard. I know the ZM chips went from Haswell to Broadwell with the help of our beloved phoenix (I mean Prema, not the one formerly known as Matrix Leader).

However yes, Volta is a long stretch. No guarantees.

You can do far more tuning to the P775DM3, so this isn't a valid comparison. Undervolting a 6700K to under 1.1v at 4GHz is easy, and CLU applied to a delidded 6700K inbetween bare die and IHS + CLU on the IHS contact point to the heatsink will probably make the 6820HK look extremely hot in comparison. And the rest of the cooling system on that ASUS is modified too. You yourself aren't going to get those kinds of temps without a literal golden chip or a LOT of work.

If I needed the CPU load (I know not if you do) I would take the P775DM3. If I did not, I would take a P670RS with a Prema mod and call it a day, really.

How in blazes did you get such awful RAM? If I'm reading that correctly, that is DDR4 2133MHz 17-17-17-39-2T. Am I wrong? O_O

Edit: Also, your static voltage isn't working. 1.2v+ on the 3.8GHz run. Has anyone managed to make static/manual voltage work for Skylake? As far as I know, undervolting is the only way to go.

 

Let me think about that for a moment....... Oh yeah, it was given to me by Ibuypower.com. And when people decide to put their faith in you, who am i to argue?

 

Always opt for clevo for better unit overall

Funny thing is that with stock asus bios there's no changeable option in xtu

 

4.0ghz
And this is all without a/c.
And CLU on the CPU and GPU.

 

Yeah... sure. But I'm still amazed at where they even FOUND that RAM. They literally found under-JEDEC-spec DDR4 RAM. HOW?

Congratulations, you're officially the only sub-1.25v 4GHz chip I've ever seen. Do you have any games installed on it by chance?

 

I can run 4.1 under 1.2

 

No games installed yet. Still trying to figure out what stock is suppose to be.

Hummm, I'll let you know later what the ram is "suppose" to do.

 

Wanna try with XTU Bench like john just did? He spiked over 1.25v at 4GHz there.

 

I bet you could probably get 3000MHz 14-14-14-34 out of that if it's from Samsung. Especially with voltage control. I look forward to your exploits sir! *salute*

 

I would just buy some 3k or 3333 ram in the near future.....Maybe.....When I'm done playing with my P870DM3

 

Well the best 3k RAM I know of is 16-18-18-43 with no listing about 1T or 2T, so if you can get that Samsung RAM better...

 

Made 6 quick changes to see if it would boot.

 

Will do, hold on

 

Thank you for the honest replies regarding the G752 vs Clevo. I tested it for two hours and will return the Asus tomorrow. I'm sure its a decent machine but there are too many details I don't like. (screen quality, massive backlight bleeding top right and bottom right, very questionable sound quality, lack of upgradeability, no easy access to internals, red keyboard backlight, overall design, etc.)

I felt that the GTX1070 is a complete mismatch with the 75 hz 1080p screen.
For the relatively lightweight Blizzard/MOBA games I play, I think I need a 1080p/120hz or 1440p screen, otherwise the GTX1060 is a better choice. I had the options all maxed plus 4xSSAA+CMAA (effectively rendering at twice the resolution - complete overkill!) and some games seemed still CPU bound at framerates over 100. I'm sure the situation is very different with current and future AAA games but I'm not too interested in those. Pascal is extremely impressive for sure.

 

As to screen and backlight bleeding. This goes for about 90 percent of screens...There is nothing wrong with it. It has to do with how the bezel sits against the screen. Now maybe they could have gone a better route here, but the screen doesn't have a backlight bleed problem as bad as one might think. You only need to massage the outer portions until the bezel is not so pressed against the screen sides.

Now the rest of that list....Well....I'm just going to let that go. .


Other news.
But it does have one thing in it's favor, but not sure till i really investigate it further....This machine will sit at 0 watts when doing nothing. I have never seen a machine do that before. So it makes me wonder if it's switching to battery. (Checked from wall)....@Mobius 1
Can you verify this as well, thanks.

 

Hmm, I do not have a UPS, cannot confirm

 

Got anything?

 

I'm trying to figure out why the system is borked on 55w now. Definitely got something to go with xtu and rog gaming center clashing.

Hard limit seems to be 75w from last test, maybe asus limit this on stock bios for whatever reason.

I know that the 6820HK on @iunlock 17R3 can do 75w+

 

Well, maybe we don't need a cmos switch....It seems it's built into the power switch.

The power button is also the bios reset switch. Now that is a total nice feature that all damn notebooks you should have!

Just hold it down for about 6 seconds and the notebook should power off and then push it again...What a few test boots then presto change o, the system comes on with factory default settings.

 

What about a full EC/NVRAM clear ?

 

Yeah, I'm not going to test that without being able to recover using say....a blind flash.

But everything seems reset, including the date & time. And it reset my bad memory over clock. So your guess is as good as mine.

Edit:

What would be stuck in EC/NVRAM that i could possible try to clear without bricking?

 

Memory timings, fan tables, etc. I meant EC Cache. Clearing those cache wont cause a brick.

 

Memory got reset, but it looks like if i say...lockout over clocking. Then do it, over clocking still stays locked out. And trip points still all appear to be the same as well, but they also don't seem to actually work right either. I set it for max fans at 23C and that doesn't see to be working. lol

 

Will you be able to forward me the BIOS/ME/EC dumps ?

 

Now that is a big 10/4 negative. That part has a lock.

 

Meanie
I meant the locked ones though.

 

It wont let me dump them. Was trying that since day one. The registers are locked from read/write access.

 

There's some issues related to sleep on my Clevo that sometimes needs me to clear it. Thankfully all I gotta do is turn it off and unplug it for a minute or two and that flushes it.

But I don't know what would happen in that ASUS. I think Clevo is king of EC/hotkey problems.

 

Sleep issues seem to be more driver related than anything else. Try the factory 780M driver that came preloaded with your system, then put it to sleep and see what happens.

 

Wait what? How were you able to modify it then ?

 

black magic

 

Lets make sure we are on the exact same page....
Backing up your own bios you are able to do. And making changes to that bios can be done.
But...
Dumbing your bios for it's settings and possible configuration files and settings for further analysis...Not possible.

Are we seeing eye to eye or am i wrong here?

 

Actually, it's my CPU that throttles to 800MHz sometimes when stressing both CPU & GPUs. If I force it with throttlestop, it'll shut off the system after about half a minute of trying to throttle. Rebooting the system does not fix the CPU throttle, I need to unplug the PSU for a minute or two while it's off to clear it.

There is another, much rarer issue where the GPU does not clock up right, but unplugging and replugging the PSU will instantly fix that.

 

this is with latest prema bios?

 

Ah, i meant, backing it up so that it can be modified using the AMI tools. Thats the backup i was asking for if possible.

 

No, Myth BIOS (it's a Prema mod though). They told me if I flashed his BIOS I'd void my warranty so until that's dead I'm not doing it.
