There are always lots of battery techs "just over the horizon" but never quite to market I think I heard about my first one when I was 12 on the way to school, that was 18 years ago

 

im sure its more or so about their profit rather than making it to the market for consumers' "ease of use". or simply because technological limitation.

cmon boys, we need that 8 core laptop with turbo boost 3.0 with new chipset. tired of these legacy software using just 1 core, it might be quicker to learn recompile the whole thing with new cpu extension rather than waiting for them to release another laptop with 8+ cpu cores.

 

Of course it's about profit in one sense, no one is going to produce a battery if it looses them money.

However that would not stop a premium option launching where they could charge an extra $200 for twice the battery life in the same space.

If the tech existed in a form it could be manufactured for any reasonable cost and with a decent amount better performance you would see it.

 

You do see some applications of super-capacitors in high end audio systems for vehicles where they put a super-cap in the trunk to power the subwoofer amplfier. As I had mentioned, further miniaturization will end up being through the use of nano materials in either a granular form or even through the use carbon nanotubes or fractal structures.

It will be interesting to see where it takes us in the future; with things like GPU chips that have 12 billion transistors and CPU's that are also approaching those limits. Crazy power requirements of ~100 watts per device and the approach to a ceiling on Moore's Law (ok, more like a temporary rule) other areas of the technology need to grow for us to take those next leaps. It is never going to be predictable or painless but as long as we do not get a super-solar flare or a war based upon EMP'ing each others civilizations that knocks us all back to the 18th century, progress will continue.

 

The issue with batteries is that we are dealing with the laws of physics rather than a design like a transistor. You are trying to pack enough energy into a space while leaving it cheap to produce, light, last over many cycles, not blow up easily and last over a long period of time without discharging naturally.

Note that lithium ion batteries are actually in the order of 100-200 Wh/kg where as caps in are in the single digits.

 

what would be an amazing thing to do is replaceable battery, a standard size and maybe with regulator for different types of power draw & make it so its in retail for consumer to purchase, i wonder how that would work out if they would actually make money off of it or not, maybe they'd prefer you buy a brand new battery like soldered bga rofl

 

any idea why CPU mhz and V drops when i turn on game (for eg witcher 3)? at desktop it is for eg 1,202 V and 4290mhz , when i turn on game , it drops to 0.700 V and 1900 mhz. Im pretty green at it, any advice? I used XTU to undervolt CPU ( used @Phoenix screen of 6700k settings)



in game

 

Which BIOS are you using? If you are running stock BIOS, throttling is normal. It's even regarded by clevo to be a feature! the only way to truly stop this from happening is by getting the premamod BIOS which is only available from select resellers. Hope that helps.

Yep, only @Prema can save you from this!

Clevo and those laptops should come with a sticker saying to people that they will throttle and they need Prema BIOS to work as they should!

 

I wish I could loose my battery for 4 x 2.5 7mm Sata 3 slots. That's how much I use my battery

 

you need the Prema BIOS / Prema EC Firmware my friend. Next time, be sure to buy the laptop from HIDevolution which is a Prema Partner or any other Prema partner of your choice

 

Future batteries, coming soon: Charge in seconds, last months and power over the air

Thanks for response laptop used to work for like idk 3-4 days normal, and just today it started to act weird.

I undervolted my machine once coz it was a bit hot. Than next day when i turned it on, it was back to default - so i undervolted it again, and next day same thing. Today i realized that CPU working on very low frequency - done 3dmark http://www.3dmark.com/compare/fs/11674093/fs/11692865

Used XTU default settings, and everything was almost back as it was - but this throttle thing started to happening.

Do you still think its BIOS?

 

maybe not then, how did you undervolt? using what tool? you may have accidentally lowered your power limits, that's different than undervolting. Also, what is your undervolt and on what CPU? Please put your system specs in your sig so we can better assist you

 

Perspective my friend, not everyone needs to be a crazy clocker.

@Rahego Can you add extra lines to the XTU graph (throttle reasons, clocks, voltages etc) and take a screenshot of it after some gameplay?

 

You're not a prema partner already? I mean, if you aren't, wouldn't it benefit you more in the long run to become one as to satisfy the demand of the market? After experiencing heavy throttling on P775 while under sustained load even without reaching the thermal point of throttling, I would lean to believe that you have more to gain if you also offer this service to your customers

I know that Clevo are not the only laptops you sell - but it might be better for Clevo buyers and satisfying demand is the first priority of sales - if market demands something, it is wise to just do that. Those machines aren't perfect, but @Prema makes them so, why not let everyone enjoy it?

 

Can't wait for any of those things to come to life!

For too long we have been subjected to recharging our phones every day!

For real now, batteries haven't really advanced much recently and phone makers are more and more afraid of placing huge batteries in their phones - this hurts our feelings.

 

@Phoenix I undervolted it using XTU. It is now on 0 (core voltage afaik - in BIOS its 0 too(was not changing anything in BIOS - just chacked it)
I edited my system specs.

@Meaker@Sager i made something like this - i guess its not exactly what u wanted:


Stop - i stopped playing witcher 3 here.

and here some screens from XTU settings.




Thanks for helping.

 

That is not going to happen. And it has nothing to do with him i'm afraid. You don't bite the hand that feeds you is typically the "rule of thumb" There is a lot more to it, but that's all i'm at liberty to say.

 

Sorry - I actually thought I'm giving positive feedback here

 

I was only speaking on the Prema Partner side of things for this one and only particular company (Sager). That is not really feedback, but more of a question as to why they are not a partner. That is how I took that.

 

I wonder whats the factor of safety clevo used when they designed these things...

Seems to be very high and they are overestimating things.

 

Those technologies will change our lifestyle, and it will be for almost every device needs battery including laptops, even our future cars.

would love that too, but wouldnt mind at least like 1hr of battery life

 

So hold on here.

Did Clevo/Sager ever change anything with the DM3 CPU heatsink?

Because with 7700K the PCB is thinner so you need to have the CPU heatsink come lower to make proper contact. So this is why the Z170 Clevo machines with 7700K have weird temp problem floating around.




Only workaround I see is to use the KM1 CPU heatsink when it comes out (god knows if Clevo fixes anything with that one) or use a shim like @TBoneSan ...

 

I didn't use a shim. I just shaved off some of the bottom on the IHS so it sits closer to the CPU Die, then smoothed out the Heatsink

 

So it's like a partial lapping? :0

 

@Mr. Fox used the shim for 7700K

 

Pretty much. I previously had a 6700k with the top of the IHS lapped. The 7700k appears to have a flat IHS so I thought I'd try it before unnessasarily lapping - turns out it made good contact and the temps are great, so I'm leaving it as is. The curious side of me wants to play with a thin shim, but I don't think there's much I'd gain if anything.

 

and how did that work out?

 

So only the CPU heatsink is lapped :0


Also kinda curious, how popular is Clevo in Japan? Are there any local resellers of them?

 

There was a reseller someone linked me to a couple of years back, I wish I could remember who. Clevo's aren't popular though (PC gaming in general is niche enough). Japan has a good selection of business laptops, but anything with a GPU is way overpriced and underpowered - it breaks my heart to see such a technologically advanced society peddle such filth.

 

Link me to websites that give me a general idea of pricing on those two types of business laptops.

Actually just found them selling a limited range of Clevo's above as 'Galleria'. There was another outfit that did it too who's name still eludes me. Check out the bottom 2 links for more interesting stuff. But all the links a worth a browse. I navigated to the laptop sections to make life easier on you

 

That limited range doesn't include a DM3 does it?

 

I didn't see it there. But I wasn't looking that hard for it. I'm sure it's available somewhere in Japan though.

 

Think the number of people who owns a P870 can be counted by fingers in JP.


Thanks for the link though, gives some insight to what's available.

 

I'm not sure about all that part there. Before I put Grizzly on there I wasted like half a tube of ( 11W/mk) Cooler Master Gel Maker Nano testing the heat sink fit. Meaning I would set it on the heat sink while the heat sink was upside down. Then I would test it in the machine. And every single time the paste was completely covered on both heatsink and cpu. No gaps. That's another reason why I like that paste as it goes on easy and then sticks to everything. I normally use that, but right now I'm using k|ngp|n paste on my gpus

 

Oh yeah, how does that paste perform? Close to LM with none of the conductive properties?


Is there any way to buy them from kingpin?

 

If you have never tried lapping it is pretty easy to do; If you remove the IHS (integrated heat spreader) as part of an effort to replace the TIM (thermal interface material) between the chip die and the IHS it will take you and extra 20 minutes to do a very decent job of lapping.

Now you "could" get a lapping compound from a machine shop or even off of eBay. If you go that route you want a couple of different grits. "ebay for" diamond lapping paste" and it costs about $2 a syringe from suppliers in China. I would go with something like a 300-500 grit for the initial flattening and then a 1000-2000 for polishing.

Get an old piece of flat glass or a mirror and put a dab of the coarse grit on the mirror with a little bit or water (or oil, depending upon what compound you buy). First flatten the bottom edge of the IHS by putting it down on the compound and moving it in circles against the compound/mirror in a figure 8 pattern. Rotate the piece every 20-30 seconds. BTW, your finger will get sore from this constant pressure and movement in the figure 8 pattern. This will remove just a tiny bit of the bottom part of the IHS material where it contacts the chip carrier.

You do not need to use 1000-2000 grit on the bottom edge of the IHS. All you were doing was making sure it did not have any edges or gouges that would keep it from being not flat.
-----------

Clean off the glass and the IHS, put new coarse compound down on the glass with a little bit of oil or water and repeat the figure 8 pattern and fingertip pressure on the surface of the IHS. You need to do this for 5 minutes or so, check periodically to see if there are shiny spots emerging on the IHS were the nickel plating is being smoothed down. When the wear pattern appears to be getting across the entire surface of the IHS then stop and clean things off.

Now you change grits to the 1000-2000 grit compound and go over again with the figure 8 pattern, periodic rotation and pressure for a few more minutes. Check periodically and you will see that the IHS is now getting very shiny and smooth. It is not going to look like a mirror with 1000-2000 grit.

If you are lapping so much that you have worn through the nickel plating and down to the copper it is not a bad thing. If the IHS is that irregular in flatness then it needed to be lapped down that much.

When done you really need to clean the IHS off with hot soapy water (like dishwashing soap and an old toothbrush) to remove any oils or residues.

------------

If you do not want to buy a lapping compound you can go to the drug store and find the old style "tooth powder" that comes in a can for brushing teeth. You can also use the "Comet" type kitchen cleanser powder that you use to remove stains on sinks and tubs. They are both abrasives and it will take longer to lap but you can still get similar results.

The most important things are the flatness of the piece of glass and the figure 8 pattern with a periodic rotation of the IHS to ensure a uniform pattern.

------------

I am familiar with this technique as I ground my own telescope mirror (but that requires polarized light and an optical flat where you are measuring angstroms of flatness).

 

They are still testing it, but it should go on sale soon though.

Side note:

Check out my new chair. Elected to grab one of these instead of a racing chair. Should be here Friday.

Could you turn the throttle reasons on (the spanner at the top right of the graph).

 

Do you have the Z height measurements for both as I was aware the 6700K was thinner than the 47xx series.

How soon?

 

I'll let you know as soon as I get an answer back.

 

Does KM support Intel Optane?

 

Do you mean that KM1 support Optane right now?

 

Well, as much as you can say it supports a product that isn't released yet ... but Intel is certainly selling Z270 as having optane support.
