How much CPU and GPU undervolting are people doing on their i9-9900k/RTX 2080 machines?
-
The z-height of the IHS is 100% the same as the original, but it has less height on the inside area only, it is making contact with the die and there is only a small gap around the perimeter of IHS in which I have put temperature resistant glue to fill the gap. So I am sure there is no problem with the IHS, it is making perfect contact with the die. I have applied conductonaut under and on top of the IHS. Before deliding with the same settings I was getting about 93-94c on full load and now its 88c. Not a big difference but at least under 90c now. Is this all I should get? Just reply to me with a yes or no, no need to type any more details
I have seen here area 51m owners overclocking it to 5.1Ghz after deliding. How is this possible without hitting 100c ? are these chips some crazy silicon lottery pieces working with -0.500mv undervolt ?

5.1 is only possible if you buy a binned chip form silicon lottery that has been short listed for that purpose (but good luck stabilising the PCIe express at those frequencies!). Generally speaking, what you currently have is as good as you can get with the 9900K or KF CPU in this machine. And regarding Z-height being the same, did you actually measure that with a vernier caliper to make sure it's the same? I wouldn't want to increase it even slightly because the power components around the CPU socket might lose good contact if there is even a marginal difference and you haven't applied extra thick pads there. The thermals in this case are bottle necked by the cooler design. I have done all that with my machine after going through a whole bunch of IHS's, replacement heat sinks and pastes, I can tell you that LM is a total waste and an unnecessary danger in case of this machine (it can and will leak out of those foam dams (especially conductonaut) if you treat your laptop like a laptop and carry it around. It is just a matter of time, unless you are willing to put in extra work and seal both surfaces of the foam dam with some liquid electrical tape to the top and the bottom with some kneaded eraser stuffed inside the socket. ) The temperature difference in case of GPU with LM as compared to Kryonaut was around 1.5 degrees which is not worth it. And with Phobya Nanogrease Extreme, I'm getting roughly the same temps as the LM, so you can choose what you want. Being a person who frequently opens/mods his machine, I don't find it useful to take the hassle to install it with LM because it is practically useless in this particular case. And if it dies because of LM, chances are that you'll blow your warranty completely because Dell is being more vigilant in testing for liquid metal on warranty claimed machines these days (based on what I've heard from support guys).
You can run LAN on windows and when you enter linux, you can continue connectivity via wi-fi because both Intel 9260ngw and 9560ngw are recognized and drivers are also available by default. (Both Intel ax200 and ax201 still lack driver support). And yes, my main boot loader is grub which sits on top of the Windows installation and I can choose which OS to run without any problem. I have a triple boot setup right now (installed another linux variant besides ubuntu mate for work purpose) and there is no problem what so ever.Last edited by a moderator: Jul 23, 2019Panda7 likes this. -

Ok Guys, here's a little update on my new rig with the Eyesafe display; it seems Dell has quietly (and cunningly I might add) removed Gsync functionality on the new panels if you downgrade the BIOS to below 1.5.4. Their business strategies get worst with every passing day. The new buyers of this system will have to run BIOS 1.5.4 and above if they want Gysnc working perfectly.
On 1.6.2: Gsync works but temp throttle limit is 75C
On 1.5.4: Same results as 1.6.2 but with more throttling and faster temp limits reached
On 1.5.0: Gsync is detected by nvidia drivers but when turned on, all the games starts flashing white lights. It has almost a strobe effect on the screen. When Gync is off, games runs normally. I've tried 3-4 nvidia drivers including Dell and the result is consistent.
On 1.3.2: Gsync is not even detected.
So, I've switched this Chi Mei panel with the AUO I have lying around and running 1.3.2 with full Gycnc functionality and the performance is the best with this BIOS. The colors of the panels are different as well. Chi Mei is brighter but AUO has more vivid colors. The response time also seems better on the AUO than the other one although I don't have any scientific proof on it. I very much prefer the AUO over the Chi Mei overall.
Finally, since I already opened the heart of the beast, I decided to repaste the Dell toothpaste with some Phobya nanogrease and some Artic pads. The results are astounding to be honest. I'm hitting max peak of 76C on the GPU running at 2010Mhz @ 937mV and max peak of 84C on the CPU running at 4.9Ghz on all cores. The temps are consistent while gaming and synthetic benchmarks alike. I'll report back if there's is some change in the near future.
In any case, thanks for reading and hope this helps someone.
TLDR: Dell is using some underhanded tactics to keep people from downgrading to better performing BIOS. I doubt we will see those initial LG and AUO panels on this machine again. Phobya is the BOMB! Highly recommend it!

How much did you spend?

Sheesh, so you're achieving 2010Mhz with BIOS 1.3.2.? And which VBios are you on?
how do you get 937mV too if you don't mind me asking? not through AWCC i'm sure..

For a high score of 25107, how exactly did you tune your GPU overclock please? I can't seem to get over 22500 so far

1: 100x100x2mm is going to be fine but it also depends upon how supple the pads are that you are using in those places. Panasonic pads are soft enough that I can cram them wherever I want indiscriminately and they squish up to the required thickness automatically but some of the harder pads won't do it, so you have to be watchful (especially around the CPU) because if your 2mm pads are not soft enough, they might not compress well and some of the components might not get good contact (partly the reason I recommend Panasonic pads).
2: If you have the heat sink on SSDs from factory, it should have it's own thermal pad on it already so you don't need to put anything extra on top.
3: Undervolting always helps reduce the temperatures further and helps the CPU to hold boost clocks for longer under load. So imo it's a good idea to test it out. There is nothing to lose if you unlock more horsepower without spending any money.
4: I haven't tried anything higher than 2tb on NVMe slots so cannot say for sure, but I don't think there should be a problem if the installed drive follows the NVMe protocol. I do have a 4TB sata ssd however (the 860 evo) as my main storage drive, which also, as per Dell, isn't fully compatible with the machine but that sounds silly. Apparently, whatever is not tested by Dell on this machine, is "not fully compatible" so take those comments with a grain of salt and enjoy whichever drive you want to put in there as long as it is compliant with the required protocol.
This paste is VERY thick and any other method except spread will give you trouble on this machine (not a lot of mounting pressure to press it out). Talking from experience here.
In this case you have to make an exception because this paste doesn't spread well due to it's chewing-gum like viscosity. If you put a dot or an X, chances are that it won't fully compress (unless you have very high mounting pressure which isn't the case in this machine) and you might end up with higher temps. I also use the pea or x method usually but in this case, that didn't work that well so I had to spread it out in a VERY thin layer.
Run NFS Payback and see how high the temps go. That game, at max settings, is a certified CPU hog! My oh my does that thing consume CPU resources! This game has replaced my CPU stability tests and I know my CPU clocks are stable if they can survive half an hour of gaming on this game.
