Anybody got a Skylake HQ/HK CPU yet? I want guinea pig-- I mean testers.

Well the i7-6785R has Iris and 128MB of eDRAM cache. Don't know if it supports extra bins, maybe not and I don't know if any Laptop manufacturers would have the balls to use a CPU with a 65W TDP. It might be an interesting project for someone with some spare coppers and fed up with their i7-6700HQ.

 

Agreed, the 6700HQ doesn't deserve to be there.. It's too weak..

Whichever way, we need more of the 6820HK...

My best FS score in P771ZM is: http://www.3dmark.com/fs/8053345

Need to do more tweaking to get the 970M to 10 000 GPU points lol..

 

That'd be interesting for sure.

The other main issue is that the 6820HQ costs the same via Intel as the 6700HQ. Like, the 6700HQ is a same-priced chip, 100MHz slower on all bins, missing I think the vPro (or something similar) technology, with 6MB L3 cache instead of 8MB. I don't understand why it exists.

 

Perhaps the ones that didn't make the cut get labeled as the 6700HQ? ie. ..JV and Varsity.

Then make the 6700HQ cheaper.

As it currently is, there is absolutely no excuse.

Besides, we already know intel can block L3 memory access on the chip. 4900MQ chips were rebranded as 4800MQs (some programs both reported them as 4810MQ and 4900MQ chips at the same time, like CPU-Z) and they lacked the extra 2MB of L3 cache that 4900MQs were supposed to have.

 

Indeed...just today I had CPUZ open in my Dell XPW 15" / 6700HQ ...and it labeled it as the i5 6300HQ...

Well, I meant "4900MQ" and "4810MQ" at the same time. Like this:

 

FWIW i7-4700MQ although not it's highest OC.

Spoiler

 

Wait how do you have a 1080 with a 4700MQ lol? What system etc are you using?

 

double post...

lol, looks like @Dufus is having himself a sweet egpu setup? and a DIY one at that! plus a 4700MQ at 4.4+ ghz, its magic

Nice score. 4700Mq is similar low entry i7 6700Hq. But have you seen same good bench result from this new low end BGA processor? I can't find similar results on 3Mark.com

 

The 6700HQ gained some nice power efficiency but nothing in brute performance over it's siblings from two generations ago. Sad state of affairs. Even the i7-4710HQ can OC as we have seen from @hdneo / EDKtheOne pulling 98W in TSBench IIRC.



Sometimes wonder if these weaker laptops are trying to compete against the ever more powerful smart phones and tablets. If so probably going to end up extinct like 3 1/2" floppies if that's the case.

That i7-4700MQ result was using a mini-ITX, something I've always really wanted in a portable system as it also has the extra items I use for work and not found in todays laptops (Serial & parallel ports). Now if someone were willing to put it all in a nice package. Ideally some water cooling as well as making use of better and cheaper desktop parts. Knowing my luck though I'd get stopped at the airport and have someone confiscate it for having more than 100cc of liquid in it :/

Yeah the GTX 1080 has been a long time coming for me, finally able to upgrade. Probably going to be some better and cheaper cards soon but that's always the way. , The 1080Ti would have been great but I've already waited too long.

 

I think they are saying the Ti for the accelerated Vega release this fall (Greenland)

@Dufus got any links for that 47 MQ and HQ overclocking? had no idea that was possible, id be interested to read more on that topic

How did you get the mobile CPU into a mini-ITX desktop? They make motherboards like these?

right now im imagining some kinda franken-machine with a mobo ripped from a laptop installed into an itx casing

I would think an embedded solution exist.

 

The overclocking is easy enough, taking care of thermals and power delivery is the hard part. Did try to get Prema interested a while back with BIOS modding for this and even though IIRC he unlocked his i7-4702MQ unfortunately it was a conflict of interests, which was fair enough. Also given the extra power and cooling requirements of a usually already hot chip it was understandable there wouldn't be too much interest. Some links, sorry that they are a bit messy.

Some OC results can be found on HWBot

Originally was OC without any microcode update but seems earlier mc version(s) can be used too and depending on your firmware may not even require a BIOS mod.

Mini-ITX come with quite a few different sockets, here's the one I am using. Other makes also exist.

Would have liked a stronger VRM and perhaps DIMM as some extreme OC'ing might be very interesting, IMO of course.

There's also BGA if you prefer although these tend to be sold with CPU soldered in so not a lot of choice in CPU but perhaps some distributors could supply custom boards or even without CPU if asked.


Some might be interested in a more potent multi-threading board, BGA 16 cores.

 

lol, wow what a contradiction, high-performance BGA with 16 (!) cores! thx for the links, ill read up asap

btw, thats insane, 5ghz!

Has anyone checked if this works with socket 2011 ep chips?

As Dufus explained it's a microcode bug manipulation (maybe BIOS mod required), but as far as I could see with the HQ chips, it's still some luck of the draw whether you'll get a chip that'll handle power limits.

Unless someone can specifically point out to me that an EC hack will allow ANY user to do it, and I can get people to try and prove it? Then I can update my guide about it. It just seems so weird that every single laptop has power draw EC issues... from all vendors... except a select few people whose chips seem to work like the MQ chips did.

 

Bigger question, does it only work on mobile?

You thinking what I am thinking D2?

 

It works on desktops. There was a big stink about Intel revoking OCing on non K CPUs for skylake, making bclk decoupled from RAM speed etc becoming worthless.

 

sooo d2ultima what is the highest stable multipler that 6820hk can sustain without crashing? 42x? 41x?

 

@ole!!! Depends to a large extent on the hardware and CPU. FWIW There's a 4.4GHz result on HWBot

@D2 Ultima the Haswell unlock appears to require a chip with some extra overclocking bins. AFAIK none of the desktop non-k Haswell CPU's have them so no unlocking for them. Of course I would be happy to be proved wrong if someone wants to try. Years ago people would try but now with 'K' or 'X' or 'C' there's a lot less reason to go to the trouble.

 

lmao 1.5v. garbage bga as expected. i personally cant stand anything over 1.35v in a laptop simply way too hot to use 24/7 without any modding.

got a decent chip 4.7ghz at 1.37v 3940xm which is pretty rare, though it doesnt past prime 95 and has no need to as it is stable on everything else i do in daily life including media encoding.

 

Haswell had limited OCing on non-K machines before they patched it out. I don't believe it was unlocked like we're able to get the mobile chips to do, but people got annoyed when they removed it. It wasn't as big a stink as the Skylake removal though, because while they didn't allow the multiplier to be adjusted, they made it so that you can adjust bclk (without being tied to the rest of the north bridge functions like RAM speed, therefore without adjusting PC stability much) and people were buying low end i3s and i5s and then using bclk to get 4.4GHz out of them... cutting into the sales of the 6600K/6700K chips... so intel cracked down and said you can't adjust bclk without owning a K CPU, which effectively makes the ability to adjust bclk entirely worthless. #Money

Depends on five things.

1 - The notebook manufacturer. I've seen 6820HKs be limited to 3.8GHz in at least one model in this very thread. OEMs might hinder the OC capabilities because stupid, so be wary. Clevo has a limit too, but I don't know what it is (it's 4.5GHz for the desktop CPUs; I don't know if the laptop chips have it that high or a little less), though a Prema mod fixes the limit.
2 - The cooling system. Self explanatory.
3 - The chip. Silicon lottery is a thing. My 4800MQ is HELL to hold 3.9GHz without shutting off my PC under load scenarios. My previous chip had no problems doing it on an undervolt (a -80mV undervolt, mind). Don't blame BGA for a bad chip... though blame it because you can't change if you have a bad chip.
4 - The power supply. Of course. If you can't provide enough power you can't really OC.
5 - The motherboard. Just because you have the power supply and you clear every single other factor, doesn't mean the motherboard can handle the voltage applied, or the power running through the circuit. The AW18 for example shuts off over around 400W applied to the board... even if you have a 660W PSU solution it's worthless for that machine.

Most chips for benches take much higher voltage for the purpose of the bench just to get it stable. It's not really rare.

 

Very inconsistent bench results with 6820HK. Look at this CB R15. Listed with almost 4.7GHz. But this benchmark is run with +- 4.250GHz. Normal max oc for the best silicon is around 4.2GHz. Highest listed Cinebench R11.5 is with 4.2GHz also. High numbers in XTU is only from better ram with 6820HK. Not from the OC on processor.
http://hwbot.org/submission/3182795_mostafa_abbasi_cinebench___r15_core_i7_6820hk_946_cb

 

so prob a stud?

 

It never enabled the processor to run a higher frequency than it could with one core active, instead it enabled all active cores to run at that frequency. Personally I wouldn't call that overclocked since the highest frequency is the same, more of removing a limitation, but I guess others might call it that. Used to run my 2.26GHz P8400 C2D with IDA bug to allow both cores at the same IDA frequency, same principle but also increased BCLK to run the P8400 at 3GHz and it was the BCLK that gave the OC not the IDA bug.

 

Awesome thread (for the 6820HK info). Thanks for this!

 

Well for fun I took the 17R3 (6820HK) for a spin. After seeing a lot of outrage of bashing on mobile chips to make themselves feel bigger in the e-peen (when it does the complete opposite) ever since the roll out of Pascal, this is just to demonstrate that it is possible to acquire a decent mobile chip like the 6820HK and that not all mobile chips are created equal. It's apparent that some are forgetting the fact that not all chips are created equal, whether it's mobile or desktop chips. *

This is also to support the thread in the performance (stability) of the 6820HK and to prove that it can sustain stress for more than a few seconds beyond its 45W TDP. (Someone in another thread had mentioned that these chips can barely hold stable past 45W TDP only for a few seconds? Forgot who, but you know who you are )

Okay so straight to the point. 6820HK is rated at 2.7GHz with a max Turbo of 3.6GHz as advertised. Well and of course the silicon lottery advertisement of 4.1GHz lol...we all know not all the scratch tickets is a winning ticket to hold 4.1GHz...but nevertheless...

This is straight up, black and white, no BS (meaning no weak bench apps), put money where the mouth is type of bench test using a true benchmark app (OCCT) that doesn't mess around with CPU load. It's the real deal. (Thanks to @Mobius 1 for the recommendation.)

6820HK OCCT Benchmark for 30+ Minutes:

Test was done with all cores @ 3.6GHz, the 6820HK's stock max turbo boost. No OC on this run as I just wanted to obtain a base and also because for this chip the Max Boost is 3.6GHz. So be it. Fair enough?

I ran it for 30+ minutes. Not 1 minute, not 5 minutes...30+ minutes. That's enough to know if the chip will kick the bucket or if it's too weak to sustain the stress.

As you can see I've used HWiNFO64, ThrottleStop and obviously OCCT to monitor the bench.

Results:

One thing that I've found impressive was how well the temps held for the 30+ minutes at 100% CPU. The readings are a little off among the three apps, but take your pick for what it is...

Max Temps:

• HWiNFO: 64, 58, 59, 57
  
• TS: 65, 65, 58, 58
• OCCT: 65, 57, 59, 56

Max TDP:

• 74.760W

The TDP hovered well above the 45W TDP of the chip for the entire duration of the test. (Myth of only 45W, debunked.)

Not bad for a mobile chip.

I hope those seeking info on the 6820HK can find this info useful.

* Okay so the red asterisk. Just a reminder that there is no gain of any kind comparing a mobile chip to a desktop chip and by doing so only shows that one is not competent enough to understand that they are two different animals. It is no secret that Desktop chips are superior to mobile chips in overall performance. Duh. It's by design that mobile chips are to run efficient in a mobile platform. A desktop is not a laptop.

For future visitors researching the 6820HK (mobile chips in general) here's a tip though:

With the roll out of Pascal, if you are wanting to game and want power, do not pay DTR prices for a MSI, ASUS etc... with a bga chip. (It is highly likely the same can be said for AW, although we don't know for certain what their offerings are yet. Pax West: Sept 2nd, we'll know for sure. I predict bga CPU and bga GPU at DTR pricing like MSI and ASUS did.) That's just stupid. Instead, opt for a DTR that can be obtained for the same price or cheaper depending on your set up. Now if you need a casual gaming laptop for fun, well just pick up whatever from the Dell outlet store with a coupon for >$1,000 and call it a day. Do not support companies that offer bga chips at DTR prices.

 

Ok so here are the results for the 6820HK 4.0Ghz (Stock Voltage) - OCCT run...

Duration:

• 34 minutes

Max Temps:

• 67, 60, 61, 58 [HWiNFO]
  
• 67, 67, 60, 60 [TS]
  
• 67, 60, 62, 59 [OCCT]

Max TDP:

• 77.618W

Only ~2C difference for the most part....not too shabby.

 

hello I tried to red the whole thread but I wanted to ask you something directly because I did'd get everything that has been said ..

I bought a new clevo P651rs with gtx 1070 and i7 6700hq but a lot of people are saying that maybe that processor is a bottleneck for that GPU so I have time until tomorrow to change my order and install the 6820hk, since they didn't start to build the laptop yet (they're still awaiting payment).

my question is simple: 1) do you think it is worth to spend extra 100euros over the 6700hq.
2) my first question depends on whether the 6820hk is stable at 4.0 ghz when oc.

So do you think I can oc no problem the 6820hk inside a 15.6" clevo p651-rs

thank you very much for your help

 

definitely, the 6820HK is a much better chip compared to the 6700HQ. I would also recommend buying a tube of thermal grizzly conductonaut / coolaboratory liquid ultra for thermal paste (best performance)
or you can get the P750 with desktop i7 for another option


My 6820HK is not stable at 4GHz, what happened with mine is probably thermal throttling since it got too hot (asus g752), I'm going to try and disassemble the laptop today...

 

These so called unlocked 6820HK should manage + - 4.1 GHz without sweating. Otherwise, Throw it in the Trash Can next. Anything else is unacceptable from an unlocked i7. If OEM's who deliver the laptops with cooling that can not cool down such a unlocked BGA..., Buy a desktop or Clevo with socket hardware. Everyone should selected Clevo or desktop anyway!!

 

The CPU VRM does not get a heatsink, only sticker with copper layer on top.







I am running 4.1ghz without any trouble right now.

Very minor throttle on 75w, seems to be the chip's limit according to BIOS.

 

Oh'' A design flaw? Tragic Is the PCH chips cooled? Can you run a Cinebench R11.5 ?

 

pch chip cooled, check my signature for detail

I will run cinebench tomorrow.

 

Not bad. Dell could not afford to put in cooling of the PCH in their AW "Echo" machines 35 cents was too much?

 

keep in mind adding a little cost to a base machine will raise 10-15x the final price due to target profit margins




also, the P65/70 series from clevo does not have VRM heatsink. @Meaker@Sager stated that the VRM is overbuilt and does not need one

P65/70 series before pascal also no PCH heatsink

 

I saw that @Mobius 1 replied back to you...so did you end up upgrading to the 6820HK? I hope so

As stated the 6820HK is a much better chip than the locked 6700HQ chip. It is well worth the extra 100 euros. You won't regret it.

 

Hahahaha, so the VRMs arent even cooled for the CPU?

This only happened on the cheap AMD MSI boards on desktop before...

 

yes

also this 1 phase memory is also not cooled

https://i.imgur.com/QZdvAQ4.jpg (bottom right)

 

@Mobius 1 @iunlock thank you very much for the answers ...

I admit I am not an expert so I really don't understand what you are trying to say about this VRM or PCH cooling ..

I understand that the 6820k is a much bettere chip but it should be useless if you cannot keep it cool right?

so I wanted to know if you think that with the 6820hk oc in a clevo p650rs-g I will have problems with temperatures

thank you

 

If you wanna go BGA. 6820 is the only option. Everything else is even worse!!

 

Our pleasure. As far as the cooling, it is highly recommended that you do a repaste, upon receiving your Clevo. For more info., recommendations, pictures and more on the best thermal paste options (GC or CLLU) click here, and it'll link you to the proper thread.

It is true that the 6820HK is the best chip you can buy at the moment for a mobile for gaming laptops. It's well worth it.

 

Ok thanks ... consider that i paid the extra in the configurator for the mx4 artic thermal paste ...

moreover do you think that 200w power adapter is required over the 180w?

 

200w PSU for sure. Wow that's the highest that they offer? I'm a bit surprised given your specs...What were the PSU options?

Is the order final yet? Or do you have time to make changes?
