thanks for reply. You think doing the simple pad stack from rams to backplate will be enough?

It's not that difficult or time consuming but you can't have a great view on thermal performance of your unit without addressing these physical defects as a design baseline.
Consider other physical mods afterwards. . . -
its the first time i try undervolting, and never repasted or padded before (i have changed components in computers many times)
All i want is a windows laptop that looks discreet (in a world of macbook's), is silent while browsing and using MS office, and can play some games when im alone.
Seemed like this computer was the right choice, but throttling down to 800 mhz after longer gaming sessions is unbearable. Dont need the 4 ghz cpu. 3 ghz would be fantastic, if it could just stay stable. -

Undervolting is easy.
Padding the memory is even easier.
You could also use throttle stop to limit the speed of the CPU to 3GHz and you may even avoid the DIMM throttling.zeverus likes this. -
I already bought all the pads and paste, so i am ready to go, but just want some stability without opening the computer first. That is if stability is an option. Which i hope is an option seeing i payed for a mid to high-end laptop.

Looking at logs from my i7-7700HQ system with iunlock's mod I do see that DIMM temps did actually hit 63C but it didn't throttle at that.
Not sure why Dell decided to change the threshold on that...
Maybe tonight I'll see how different my DIMM sensor is reading compared to the actual DIMMs themselves. It won't be an apples to apples comparison for the 9570 but it may help.pressing likes this. -
Does BIOS version has something to do with all these Thermal Throttling logics (such the DIMM sensor question)? -
how crazy is crazy? I'm at -180mV on core and -160mW on cache and I'm kind of too lazy to try to push the envelope on my own.
-
you are actually at 160/160. The system takes the minimum of the two.pressing likes this. -
-
are you sure? I was at 180/160 and some errors cropped up, I drop to 160/160 and they're gone. -
So, I got a 100,510s at 160/160, but I run it again and errors crop up. I continue to reduce the undervolt and stop the test when errors crop up and I got 100,297s at 145/145.
Also, there's no option for 6 threads, I've been running 12. -
Maybe you had better luck with your chip. -

So i understand a lot of you guys ended up returning the laptop. But what laptop are you guys going to buy instead?
The main reason i got this laptop was because i needed a 13-15" light weight and slim portable laptop with a decent battery life to browse web and use MS office.
My minimum requirements were 8 gb ram, 128 gb ssd and intel U cpu would be fine. I never needed a dedicated gpu. I was considering a zenbook 15", ideapad/thinkpad 14"/15", MS surface 13", macbook 13".
But i got a 33% discount on the XPS, and all the other computers in the same price range come with 4-8 gb ram and 128-256 gb ssd and slower cpu's. The XPS i got was with 16 gb ram and 500 gb ssd, and better CPU. The faster cpu and dedicated gpu is just a bonus that wasnt a requirement for my needs.
When power plan is put to silent mode, it lives up to all my needs, and in this regard only weight and thickness are downers for me.
No matter what "best ultrabooks guide" i read, the laptops on the lists are either far more expensive, or far lower specs. Some are thinner and lighter, but aside from that, they mostly seem to suck compared to this machine at the price range.
If anyone knows a laptop that is at least 8 gb ram, 128 gb ssd, slimmer and lighter and long battery life at same price range (compared to a 33% discounted xps), i would appreciate any recommendation.
I think the xps 9570 is a winner when it comes to my basic demands, but any recommendations are appreciated. -

Hey guys - can someone please do a Cinebench run or something similar and let me know what speeds you maintain with and without hyper-threading? I'm looking at upgrading from the 9560 to 9570 to speed up compilation which isn't heavily multi-threaded, I need pure core speed. I'm not fussed on what CPU you test on (8300H/8750H/8950HK).

@Brimmy this will give ou an idea of what i5-8300 can do -
There are gaming laptops with i7 8750h and 1060 around $1100 mark.
It's probably even going to be better cooled because you have more space for the heatsink.Woodking likes this. -
I think it may be time to leave Dell and dip my toes in and test the water in another laptop manufacturerLast edited: Feb 12, 2019 -
All the other premium thin laptops (razor/msi gs65 etc) are *significantly* more expensive and have thermal limitations as well, even out of the box (let's not even talk about the macbookpro).
EDIT: To be fair the other laptops have a 1060. That might be important for a gamer.
You can improve the performance of the XPS15 (and probably of its competitors as well) with the usual tricks.
In particular, for the XPS, I would recommend anyone to do these things in order effectiveness (and complexity):
1) Undervolt CPU (easy)
2) Undervolt GPU (easy)
3) !!!Pad the RAM!!! (easy)
4) Repaste (medium difficulty)
5) Pad/Mod the VRMs (this is really optional)ovasquez19 and pressing like this. -
If Dell sell X amount of these and people are happy to do their own mods and keep them then nothings going to change, they'll keep cranking out laptops that won't run as advertised and get away with it.
Not out to argue with anyone here but this isn't going to get any better unless we hold these manufacturers to account for making lousy products and using the 'max power' and 'ultimate experience' advertising while knowing they cant stand up to their claims without users modifying them.
Glad I returned mine, but sad I had to being a long time Dell customer.Last edited: Feb 12, 2019 -
I agree, but the reality is that there are no manufacturers making a laptop like we want. The XPS is the closest -- but what's worse is that Dell is moving towards apple's model of heat and slow speed in exchange for quieter operation. Things are only going to get worse.jeremyshaw and Woodking like this. -

@Woodking
I was aware of the potential issue before buying (I read @Eason blog and visited the forum).
Actually, I was expecting much worse.Points 1-3 are really easy, you don't even have to take anything apart. Repaste may make some people uncomfortable. You don't have to do the VRM part.
However, I do agree with you on a certain level.
I think the original sin is Intel's inability to have a working 10nm process (they are 3 years late).
The TDP has become a meaningless number. These 6cores CPUs are hotter than the 4 cores of last year (because the lithography process is the same 14nm and you have 2 more cores).
This does not excuse the manufacturers, Dell and all the others, who are well aware of these matters. And yeah, we shouldn't have to do these mods.
For me, the XPS15 was the cheapest of the bunch (also the one that I liked most) and I need a new laptop.Woodking likes this. -

Are there any real alternatives to the XPS15 that can actually handle a CPU like a 8950HK without being something in the size of an Alienware 17 R5 or such? I mean, the laws of physics are hard to change so enough heat combined with unsufficient cooling can only give one result. What about the slim gaming laptops that are showing up now, like Razer Blade 15 and simlar? Have looked into them for a few years now but all seem to come with one problem or another making them less than optimal for "productivity use".
-
I don't think the blade has the i9 option (and it's the right call !!!). Anyway, the Blade has the TDP of the CPU reduced to 35W (instead of the normal 45), so it will perform worse than a comparable laptop with the i7-8750Last edited: Jul 25, 2018improwise likes this. -

@_sem_ I have the laptop and I can report on what I see. The DIMM sensor *has to* be taken care of. The VRMs may run hot (at least the ones close ambient1, which are GPU related) but it's not a direct cause of throttling by Dell's power/thermal management.

The new XPS has 2 more cores and "higher clocks" but essentially the same cooling solution for three generations. And there are all kinds of timers, power limits, heat limits, etc. that will prevent these max frequencies from sustaining.
One trick I use on an older 6300HQ to enable 2-core max turbo speeds all the time (even with all cores running) is:
1. Disable "c-states" in BIOS screen
2. Use ThrottleStop to enable SpeedShift (with EPP=0)
Worth a try on the 9570 as I get an extra 200MHz. And with c-states disabled, from a practical perspective, the CPU may run some tasks faster.
Downside is that the laptop runs hotter and consumes more energy so for very intensive use this trick might not help so much. . .
This is a scenario that Dell probably forgot to lock out. Might not work on the 9570 because:
1. Dell might have fixed that oversight (doubt it)
2. 9570 has SpeedShift in the BIOS (try disabled in BIOS and using ThrottleStop)custom90gt and abujafar like this. -
I have the feeling that Lisa Gade read this forum.
I don't know if it's just me but I think people are being overly negative about this laptop.
Yeah, it has some issue (that can be alleviated) but overall is fine.Last edited: Jul 31, 2018 -

People just like to bash. The better the device gets the more people criticize it. I guess it's just the way it is today...
But that doesn't mean the laptop is bad. Actually, it's a great laptop.
I don't know what people expect - a desktop power horse in a laptop that's thin and light? And if it doesn't perform like one then pour the tar and spread the feathers over it? And even if it performs good then find whatever flaw you can think of, just because...
People getting spoiled, me thinks.
