    SK Hynix has been in the game for a long time now so the quality of the drive isn't the issue. It's not a particularly fast NVMe SSD, but it's faster than SATA SSDs. Since 99% of users won't notice a difference between a fast NVMe SSD and a SATA SSD, I would say there isn't a benefit to it. If you want a larger drive then sure go for it, but in terms of spending money just for a "faster drive" I wouldn't.

    Hi,
    I've got a problem with my XPS 9570, it's . After I bough it and read all the reddits and this thread, I did the repaste, undervolted the CPU + cache, but my results are more than disappointing.

    My results are 98° max temp on CPU package while running RealBench. GPU temps are generally around 74° while doing some GPU intensive tasks.

    I repasted the laptop with the same Kryonaut 3x times already to make sure I haven't missed any part or made a mistake.
    CPU is undervolted with -0.2V and cache -0.105 (with lower values on cache I get either errors in ThrottleStop bench or BSODs).

    I'm wondering what could be the problem, if it's the paste job or bad heatsink. I already put some small heatsinks on the VRMs to reduce the temperatures there, previously I was hitting 111° Celsius on VRM.

    Any ideas?

    Even at minimum usage you cpu seems to run pretty hot.

    Did you inspect to see if your cooler is not bent ?

    I mean my modded 9570s still hit ~96C running RealBench. What are your average temps? Spikes really don't mean much as it takes time for the fans to kick in. How are your idle temps? It could be a bad/bent heatsink that is causing poor contact of the heatsink. Do you have any other thermal paste to try?

    Idle temps are ~44C, now running prime95 small FFT for 30 minutes gives me average ~83C CPU package temp (clock around ~3140Mhz), in spikes it can still get to ~98C.

    I don't know now, if this is good or bad? When I read your first post and saw those small spikes and averages I was really suprised that I'm getting still that high temps.

    I don't have any other paste to try. The heatsink looked fine to me, though while removing it I bent it a little, but now it's almost flat.

    Hi, i am sharing my results using real beanch with only undervolting.

    I am just curious to see if these results and temperatures are good considering i only undervolted so far. without undervolt my computer was going even to 90 on iddle, light tasks. with undervolt i dont go more than 60s when using photoshop or playing games like shadow of the tombraider or fortnite.

    Any feedback is appreciated. thanks!

    Hi,
    I think your temps are good for the settings you have used. But know that you don't have the stock turbo ration settings for the CPU. Stock is 41/41/40/40/39/39. You're limitting the CPU turbo ratio to 30 for all cores. So in your case it never clocks to 3,9 Ghz.

    Hey guys,
    I was wondering which VRMs to pad to the bottom, to reduce how hot the laptop gets in the middle over the keyboard?
    I run a -135 mV undervolt, and while gaming I also turn off the turbo boost, so it just clocks till 2,2 (runs like 20 degree cooler, with no performance loss)
    I haven't repasted or installed a new, unbloated windows yet, but I will install a fresh one next week.
    Thanks for any help!

    I don't think that padding anything will help with the keyboard getting hot. In fact attaching anything to the case would likely cause it to get hotter since it really can't deal with much heat anyway.

    Hey guys,
    I'd like to say a couple of things before anything else.
    As English is not my first language, please forgive me If I have grammatical errors or get some words wrong. Also, I'm new to this forum, I think I'm commenting in the right thread, but If you guys think I should comment somewhere else, please let me know.

    So I recently purchased my XPS 15 9570 the i7, 4K w/ 512 Gb SSD
    I having reading this thread amongst others for trying to get the most out it, but most of what I find out there are focused on performance.
    As right now, I'm more concerned about battery life than performance, and since you guys have sorted out pretty well the last one, my questions are related on trying to get better battery life.
    I know that getting a 4K panel is not the smartest decision for that matter but I wanted to have the touch-screen (I'd have been more than happy with an FHD touch-screen with good colors)

    So my main goal is to have a powerful machine when I need it but when I don't, being able to go through a full day without the charger.
    Since when I'm out of home my usage is not intensive whatsoever (Reading PDFs, taking notes and browser usage) and the battery on this laptop is pretty beefy, I think I could get away with not bringing the charger.
    Even though I've read some threads, the Throttlestop guide and watched a couple of videos I still have some question that you guys might be able to solve for me.

    1. If I have Speed Shift enabled, should I disable or keep enable Speed Step and C1E? Since I'm not sure If I understood what each of them does.

    2. I have Undervoltage my CPU, Intel GPU and Cache is there anything I could modify? Iccmax, VCCIN, Turbo Boost Power Limit ... Or maybe some BIOS settings

    3. If I disable Turbo or Underclock the Turbo ratios should I be able to Undervoltage to even lower voltages? (As my tasks while on battery are mostly light, I think I could be more conservative with Turbo settings since I don't mind waiting for that half-second more to load a Tab in Chrome)

    4. Do the Windows slider have some effect? That's kinda off-topic, but I have noticed that the Procesor Power Management under Power Options (The one that would limit the CPU to a certain % of Load) have disappeared and I think read that have been replaced with the Windows 10 battery slider, but I'm not sure If its just a Dell thing and they control it over one of their software or it's just gone/replaced by the slider.

    5. C States. Okay, let me know If I'm getting this wrong since I'm really sure. So in order to decrease power consumption during idle states, the CPU goes to some sort of Deep sleep state, which would correspond to the C states. From what I read some manufacturers disable this setting, but as far as we know Dell hasn't done that.
      Okay, then my question is, on ThrottleStop we have Core C State and Package C State. I see that while idle the Core C state has a 0-1% on C3 and 88-96% on C7 (This values might be lower or higher) as far as I know, this is good.
      And then I look to the Package C State and I see with a Total Percentage of 50-65% most of it is on C2 State and may 0-1% on C3 and C8. I really don't know how to interpret this information.
      I have tried closing Chrome and Rainmeter, which I see that keep the CPU at 1-5% of usage and the C state shift to having around a 20% on C10 and some other at C8, but mostly stays on C2.
      Also, the average clock speed goes from 2-2.4Ghz to 1.2-1.4GHz, so I think that's good.

    6. Speed Shift range. On the main settings, I can input any number from 0-255 on the Speed Shift - EPP setting, but the If I open TPL (Turbo Power Limit) and go to Misc, the Speed Shift range is 1 - 41 and not 0 - 255. Are those 2 different settings? Should be the same range?
      Screenshot of the settings

    Then I have aswell some questions about Dell's included software (I ask here since you guys seem to be familiar with that, but let me know If I should edit this part and ask somewhere else)

    I read that a lot of users recommend doing a clean install of Windows 10 since that would remove all the bloatware and so on, but I did already set everything up so I didn't want to go through the struggle again.
    What I have done is Disable all auto start, Task Schedule, and Services from all Dell related software, so they don't consume any resources but only storage.

    I kept it just If I need to use it someday, but I wanted to ask you guys which of the following programs are actually useful and can be removed.
    The only one that I used is the Power Manager, which I think is really useful for longer battery longevity, but apart from that nothing else, only the Updater for the BIOS update.

    So yeah guys, I hope you can help me out with this questions that I have.
