The Official MSI GT62VR Owners and Discussions Lounge

It varies by BIOS, and by generation, but yes in general the K processors have unlimited or variable limits that can be "pre-set" in the BIOS - so no timeout and no power limit, just cooling and MB power delivery limitations.

 

Yes I actually tried everything.. It won't go past 3.1ghz when you're using 4 or more threads

Without seeing a full blown review on the 6700T we're both just speculating on it's performance.. I am expecting the 6700T to actually sustain a higher speed than the 6700HQ.. Maybe even by only 100mhz but it's still something. If I can come across a cheap used 6700T to play with, i'll be happy to test it and see what my findings are.

 

It's a nice thought, but how will the 6700T sustain a performance higher than it's power draw? It can't.

It's going to be limited by power available to it, and every increase in clock rate x 8 cores is going to take more power.

It might be more efficient at lower power range, IDK, so it might get 2.8ghz...

I guess someone is going to need to try it

 

I finally managed to get an importer agent so I will be placing my order soon in HIDevolution yay~

Just a couple of questions

1) how are you guys doing the clean install of windows 10? Just a recovery usb and drivers from the web page of msi right?

2) Which program are you using to undervolt the cpu XTU? (Which version?) will I have any issue if I have it installed with the dragon center?

3) Which driver version are you using for the gtx 1070?

Would you please run that test again, and let us know the package power draw at sustained 3.1ghz x 4 cores?

It should be less than 45w, as that package will do 3.55ghz @ 45w on 4 cores.

I'm going to estimate 39.85w or thereabouts with best undervolt at 3.1ghz with 4 cores + max fans for cooling.

 

Points 1 & 2 were already discussed in this thread.use search and xtu & then clean install or installation.

 

Finally got my tracking information... I sincerely hope it was worth the 4+ week wait.

 

A newbie question can make a lot of posts Still dunno what to choose... but I'm a bit more "clever" now. Thanks

 

Same. Mine doesn't have a delivery date though. What does yours say? Mine simply says shipping label created and delivery date is like pending.

 

Remember guys that TDP is not the power a CPU consumes. It's a heatsink design minimum dissipation limit for the CPU to sustain a 100% load constantly. In electronics (especially in microelectronics) voltage has a more strict range then current. It's what actually diferentiates a 1 level from a 0 level logic. Current on Intel iX CPUs can be as high as 120A. However such a high value can only be sustained for a short while (the reason why we get a short burst of power during boost clocks). Afterwards it falls in the long term working regime. A lower temperature means a more "fluid" electron "flow" in the silicon which results in a higher long term current and more power available to the CPU to sustain the frequency "stress".

By undervolting you lower the heat dissipated thus the above condition is met. Previous CPU generations had their VRM controllers integrated. Now they have (once again) been relegated to the motherboard and the CPUs locked down more except for K variants which have the unlock flag hardcoded.

The 6700T is an high ASIC unit running at a sweet spot in regards to heat, power consumption and performance curves. The yeld is lower however versus more common models (6700k 6700hq 6700 etc). It can run on lower voltage than normally but locks on boost frequencies for longer.

CPU manufacturers don't have it easy

 

What says that 35 watts cannot provide more performance? It's obvious it's a golden chip that is pretty undervolted out of the box to achieve low wattage and more performance.

I don't understand the logic. My 6700hq pulls 3.1ghz on all cores at only 31 watts.

 

Give it around 2 hours for it to go through their system. Mine says next Thursday for delivery.

 

Can't wait to get my hands on her. No idea what they're shipping me as I can't see my order # anywhere.

@Diversion where did you find they updated your order as no logo??

Edit never mind I got a no logo version.

 

Agreed they're most likely very well binned but locked down 6700s. Getting a 6700k to that low of tdp probably won't happen unless you get one of those cherry picked samples.

Regardless I'm only interested in making my 6700k do 4.0ghz stable on all 4 cores while keeping it as cool as possible. 3.1ghz wasn't a bottleneck for my 1060, but in certain titles it would for the 1070. 4.0ghz i7 will let the 1070 fly.

 

It will not do 3.55ghz when all 4 cores are loaded no matter what. So unless my cpu being held back by the bios I don't know what to tell you.

Intel specified that the CPU only does 3.1ghz when all 4 cores are loaded so how can you defeat that?

 

They attached a new invoice when I got the tracking number that showed NO LOGO on it.

 

Edit: I see the confusion, when I said that package can do 3.55ghz at 45w, I meant that CPU line in general, not the 6700HQ specifically

Well of course if the BIOS limit's the cores to a limit under 3.55ghz, it's not gonna work higher...

I was interested in hearing what the package power draw is at the 6700HQ sustained limit (of 3.1ghz), with maximum undervolt and outside the turbo boost timeout.

I am thinking it's not going to even make it to the 45w power limit, since the clock is limited to 3.1ghz...

What is the package power draw during 100% cpu at sustained clock of 3.1ghz?

You can see it in hwinfo64, here's an example from the GT80 980m SLI with a 5950HQ CPU set to 35x on all 4 cores, running for 1 hour at a sustained average package power draw of 45w:

Sustained 35x for 1.05 hr at 45w - xtu settings 35x -105mV 35x cache 0mV

 

I looked it up but my question was aiming at the point of which combination of software won't cause problems in the cpu tweaking and still will give me control over the fans.

Dragon center also works over the cpu?

I'll test and provide pictures in a bit.. what test do you want me to load the cores up with because prime95 AVX will draw a lot more power than a non AVX bench.

 

Ah, sorry I hadn't read back far enough.

So the 6700HQ only draws 31 watts @ 3.1ghz all 4 cores, so that's way below the 45w package limit... wild.

IDK what the 6700T will hit for sure, my guess was 2.8ghz based on how the TDP limit of 35w would balance against a CPU with a 45w limit.

If yours is only drawing 31w/45w, how will the 6700T perform?

My guess is less / same performance as the 6700HQ.

 

I pulled the first example from my snapshot archive, which was for a batch processing job that runs on CPU / 2 x GPU's 100%, pretty brutal and a good measure of cooling and power delivery. Folding@Home from Stanford.

I could have just as well disabled the GPU jobs and only run the CPU jobs, but that would offload the CPU however briefly while the CPU job ended / and the next one started. The GPU loads also require CPU work and kept the load constant.

But, you can pick anything that will sustain 100% CPU load generating maximum power draw, pushing that 6700HQ constantly at 3.1ghz (or as high as it will go under heat/power draw) up to 45w.

See what works for you. It would be interesting to see if you get the power usage up past 31w while running at maximum sustained 4 core 100% CPU loads, I'm thinking with the right work load you should be able to at least sustain 39w.

 

Also, I used to run a GPU test simultaneously with p95 to keep the power draw up - even with 8 threads there are CPU peak drops running p95, so running something else in parallel to soak up those peaks with additional CPU usage keeps the power draw right at 45.xx watts.

 

Looking forward to the desktop reviews of this unit. Please give us initial sound impressions, battery life, and temps.

I must say, giving the GT62VR back is going to be hard. I have thoroughly enjoyed this unit and even though I have a 1080 desktop I found myself gaming on this unit. I have never owned a gaming laptop that runs so cool while under load and quiet at the same time, has an awesome keyboard, and pretty awesome speakers; it is almost unbelievable. I will say last night I had some hiccups to where the GPU was struggling despite temps being OK which directly impacted my FPS in Overwatch. I almost think it had something to do with GSYNC and it screwing up frames as they were jumping all over the place and I know for a fact this unit can run Overwatch max settings @ 1080p.

Wish list for next refresh, please give us a 120hz screen option and I will be the first to preorder.

 

If this laptop had a 1080p 120hz+ g-sync display it would have been an absolute slam dunk. But there in lies the problem. How will MSI sell their next laptop if they give you everything in a neat little package today? They need to have something to market when Kaby Lake drops.

 

If anything the display problems this generation shows these makers don't hold anything back, they offer what they have and more, and there is nothing more to "save" for the next releases.

Kaby Lake motherboard chipset + new CPU's + new storage options + whatever other voodoo they can "name" between now and then will be what is offered as it is available, probably before it should be released

 

We'll make it the best laptop by upgrading the screen ourselves soon.

 

Here's the TS Bench built into ThrottleStop wattage:


And here's Prime95 AVX (almost 45 watts):

 

Is that 44.6w current power draw? @ 55c that seems highly unlikely.

Can you please install hwinfo64 and get that monitoring view as I posted earlier?

It has Current, Low, High, and Average readings for all the monitored values.

Plus it does logging, so you can see the values and trends in between the lows and highs, but that's for another time

 

And here is showing where the Multiplier is completely locked:


Even though I can set it to 35 it doesn't matter..

 

I didn't let it run long enough.. here's 10 minutes of the same Prime95..

This is also using my max undervolt settings.. It will power limit throttle on stock voltage and go down to base clocks of 2.6 to 2.7ghz. During this test it never dropped below 3092mhz.

It's dead silent and runs cold under a Prime95 AVX test (After about 10 minutes):

 

Thanks, that's awesome, so the maximum package power at full boost is 44.157w @ 31x, that's the problem then with the 6700HQ, it goes above 31x even at max turbo due to power throttling + locked options.

And, as I estimated the settled sustained power average is about 39w - 38.6w. Which scales from my 3.5ghz @ about 45w (see previous hwinfo64 image post).

So the 6700T estimate would be around 2.8ghz @ about 36w. This ones more of a guess than an estimate given the differing chip characteristics, but I would be surprised if it was far off from this.

I guess we won't know until someone gets a 6700T and runs it for benchmarks and monitoring

 

Yeah, it'll be unlikely i'll seek out a 6700T for testing in my barebones.. Surprised nobody has done any extensive testing on one because it's only an interesting chip to those use seek a very energy efficient desktop setup.. But I did read about someone's experience where they said it was in the high 40s under load using the stock IHS which is completely wild low temps for a decently fast chip. Of course I doubt they tried a AVX test for theoretical max temps.

 

This is the review I found:

http://blogs.tigarus.com/patcoola/2016/08/31/intel-i7-6700t-processor-review/

It's not very extensive though..

 

The 6700T is an odd beast, maybe for specialized applications where they need a full desktop CPU but require less power in that application use - a Tablet comes to mind, or an embedded controller.

I haven't found any mention of designs with the 6700T, except for one early on, it was a part of the bread board development kit... can't find it now..

 

Wish they made a BGA version for notebooks.. makes more sense in that market for lower temps for good performance. It's weird to make a LGA version of it as I just can't see many people using it since when idling, all Skylake desktop CPUs should technically idle within a watt or two of each other.

 

It might just be for devices like the Vaio Z Canvas Tablet, which shipped with the 47XX series CPU, the 6700T would be a drop in replacement, but that's just a wild thought, I haven't researched it

 

Or a good CPU choice for a machine that needs to do heavy lifting nearly 24/7 a day where the max TDP would cut energy costs in half without having to sacrifice a lot of speed vs a standard 6700 or 6700K.. This is probably what it's mostly designed for. It would make a good CPU for a small Virtual Machine host without costing you a ton in energy costs. Or even a home NAS unit (even better idea there). I bet if I researched QNAP/Synology you could probably get a unit with the 6700T where it would be amazing.

 

But in regards to the barebones MSI, you could probably achieve the same TDP results by undervolting the 6700K down to 6700T levels and get the same average energy savings.. The 6700T is a premium cherry picked sample that is 100% stable at like 1volt or something at up to 3.6ghz..

On the other hand, the 6700K is also a cherry picked sample (to a lesser premium) that is 100% stable to do 4.2ghz at whatever voltage.. It may also happen to be able to undervolt a ton so you get the best of ALL worlds.

For example, set the 6700K to 3.6ghz and undervolt it a lot.. Bet you could be faster than a 6700HQ while roughly achieving the same wattage and temps..

 

My 5820k is 100% stable for 2 years at 4.2ghz all 6 cores under load @ 1.17v.

Will find out soon enough just how stable and fine tuned I can get my 6700k.

 

What is going to be less ideal is having a LGA cpu with a TIM plate on the CPU in the barebones.. Now you're having to cool the LGA cpu through another metal plate.. BGA being a bare cpu die against the direct cooling plate is better for heat transfer.. So i'm pretty worried here.

 

Sounds like you won the silicon lottery on that cpu.. That's quite a low voltage!

 

We'll be fine. I can't foresee 4.0ghz cooking this beast.

 

Due to the low pressure heatsink mating in laptops, and their tendency to rotate under varying loads - people picking up their laptop by a corner, the desktop CPU package is problematic to keep aligned.

The best custom tuning uses shim's or pads to even out the load across the heat plate to keep even and constant pressure so the edges don't lift and let in air that oxidizes the TIM and degrades performance rapidly.

Some people need to re-paste every few months - those that have to have the absolute lowest temps - any rise and they pull it all apart again

If you delid the LGA CPU, and use a liquid metal between the lid and the CPU it will press the lid back onto the CPU carrier and provide an air-tight seal so at least that TIM won't oxidize as quickly. And, that provides an almost as good thermal bond as the bare BGA mating.

 

I have Coollaboratories Liquid Pro for delidding.. I was planning on doing it to help out thermals but I probably wouldn't do it very soon unless i'm seeing terrible temps.. Good info though!

 

Oddly enough my shipping doesn't show anything yet....

 

Mine only showed shipping label created until the next day as well.. Patience dude! What does your delivery date say?

 

Monday. I leave for work the next day so I'll be home to get it and tinker and install everything.

 

It shouldn't change... we get our junk on Monday! Yay.

 

Oh and cheers to us getting on hopefully having good luck with golden builds and CPUs and 1070s. I am hoping for the best for us daring individuals to take on this rare challenge.. Lol. All 3 of us who ordered the setups! Here here.

I have a good feeling we'll love the damn units.

 

6700T's are all over Ebay for a buy it now price of $250.. Definitely a better price than going new but still :/
