The performance is pretty inconsistent with the battery disconnected. The GPU floats between 60W and 120W while the CPU is around 45W. I guess it does not want to get anywhere near the higher performance limits so a transient spike does not trip the power supply. I tried to ask Dell for a way to disable this feature as I prefer to keep my battery charged at 80% reserved for use when needed. Nor do I want the excessive wear and heat as it continually drains and recharges under the supposed 200W sustained load capability. From what I have heard this is working as designed.

There is probably a hidden bios option in there somewhere I have not found yet that flags it to require CSODIMM. It can boot aftermarket CSODIMM modules not sourced from Dell. 24GB Hynix modules work well as single rank timings are better and the modules generate less heat than dual rank. The CAMM2 modules have a heatsink built for them so that is what I would choose if I needed more than 2x24GB (highest single rank capacity). My biggest annoyance is still the battery drain under load that is by design. I have a custom charge range set from 70% start to 80% stop, and if the system is under load it is basically always either discharging down by up to 20W per hour or charging back up at 5W (trickle) - 60W (express). Sometimes it decides to express charge the battery even if you are under load so whatever compute task that is running just gets throttled instead. I have even seen the firmware trip some kind of internal throttling protection where the CPU refuses to go over 20W until you unplug and replug the power adapter.

If you can find 64GB CSODIMM modules they likely would work. But I think the regular SODIMM 64GB modules available from Crucial currently would not work as the system would not post with a SODIMM installed when I tested.

@AL123 Have you been able to test the TB5 dock to see if it reduces or eliminates battery drain with the higher 300W power delivery? I can see the CPU pl1 is dynamically set to 58W so combined with the 175W for the GPU seems like it's consistently too much.

I spent a couple of hours using the laptop last night at full load and at some point it went into a throttled CPU mode where frequency was being clipped to under 3ghz due to psysPL2 according to hwinfo. After checking a few things unplugging and replugging the USBC charger got the CPU up to full performance again. Also of interesting note the display appears to support advanced Optimus. However only VRR in regular Optimus mode.

Ah that makes sense. I don't mind the plastic surface. It's higher quality than the latitude palm rest. All that matters to me is surface temps not be scalding. I do believe they are better than the precision 7780 was.

Yeah I found magnetite in the promotional materials and I guess the keycaps are the same material? The palm rest looked like plastic from first glance at this image: The magnesium alloy cage is around the bottom area of the palm rest, as you can see here: Throttlestop and XTU do not allow adjustment of undervolting or most multipliers. That all falls under the overclocking umbrella which cannot be enabled. PL1 can in theory be overridden but may interfere with Nvidia power limits.

I like discussing performance and comparing it against others. I agree an owners louge is about due. Well its possible I was wrong on the palm rest material. I was going back through the docs and everything says its supposed to be Magnetite, which is a metal. It may be injection molded plastic bonded to the metal, but hard to say from the photos of the palm rest compared to holding one in hand. SREP is a tool that patches the bios at runtime to show all configuration options available. In the case of the Pro Max 18 Plus bios it appears that Overclocking is not compiled in, so still unavailable. However, memory overclocking is there so I did a quick test disabling SAGV and setting tREFI to 16k both of which worked. SAGV is probably something you would want to keep enabled as it can reduce battery power consumption. You can also set TccOffset so the CPU throttles before 105C if desired. Unfortunately we cannot adjust D2D (21x) or NGU (26x) clocks and sadly the 285HX is not a higher bin on those than the 275HX. These are the parameters Intel calls "200S Boost" on desktop along with activating XMP. Right now I am trying to figure out what the threshold is where battery drain occurs. It appears that 200W in Ultra Performance mode is enough, but 170W in Optimized mode does not. It seems like the "Adaptive C-states for Discrete Graphics" also causes it to drain the battery more agressively so it may be best to disable if you care about battery health. My machine needs a repaste job as it thermal throttles at 200W but the CPU PL1 is being set to 58W in combined loads so in theory it can pull more power.

@Easa yes the surface of the palm rest is a smooth plastic. There is a mag alloy rib case to give it rigidity. It's a similar design to the p16 g2. Also I believe only SSD slot 1 is gen5. SSD slot 2 is gen4 but also CPU pcie lanes so it's the best place for a scratch drive. Slots 3 and 4 are connected to the PCH. Tb5 uses pcie lanes bifurcated from the GPU. Hence why the GPU is 8x instead of 16x. Sorry for moving it but I wanted to try and keep non-performance discussion out of that thread. It has been fun benching the pro Max 18 plus over the weekend. Oh, and SREP does work to modify a few performance parameters.

Yeah the palm rest is plastic but I like the feel of it more than a metal or rubber finish. In Ultra Performance mode RAPL sets PL1 to 58W, and the GPU can go up to 175W. So in theory it is designed for up to 233W sustained. However I see battery drain at 200W sustained with thermal throttling so beyond that will need lower ambients or a repaste to see if it can really go higher. The Dell TB5 dock is also supposed to supply up to 300W. I do not know if that extra is utilized or could prevent the battery drain. A TB5 eGPU could work well here if it has improved the latency and bandwidth over TB4. I saw they are starting to test TB5 out over at egpu.io forums so it will be interesting to see how they do. We have both TB5 and TB4 on this machine wired to CPU PCIe lanes so its easy to compare both. https://imgur.com/jxLwhNE https://www.3dmark.com/3dm/142596374?

W10 support is rare these days. I found one setting that seemed to stop the battery drain so far. It is called "Adaptive C-states for Discrete Graphics". With it disabled the CPU stays at 30W and the GPU stays at 140W in Optimized mode and battery drain does not occur. I would think if its designed for up to 200W combined loads then that should not include any battery drain in the specification. The palm rest is no longer rubbery! Its a nice chance from the previous generation.

Its the default paste job which is not PTM from the looks of it. However it is also not E31 either so we do not have to worry about leaking LM shorting the motherboard. The interesting part about its cooling design is that the vapor chamber sits between the CPU and GPU. The fans can also be removed easily for separate cleaning which is nice. I actually get quite a bit of dust build up on my machines as I am not in a climate controlled environment. Sadly the Alienware is a consumer gaming oriented device so it ends up dragging along all of the stereotypical characteristics that I hate. Performance wise with this generation the Consumer and Business model are very close. Its a more expensive 5090 mobile variant but does offer comparable performance, VRR support in iGPU mode and I think the drivers should work as well as Geforce as long as its not trying to play a new title on launch day. So far WoW has not had any of the weird BDPROCHOT throttling I experienced on the 7670, 7770, or 7780. The iGPU clocks itself at 550mhz under load but I guess that is enough for Optimus and UI snappiness.

@electrosoft Starting to run the Pro Max 18 Plus through its paces. https://imgur.com/a/32ivRNC https://www.3dmark.com/spy/58934149 It has full W10 driver support which is great. Surprisingly enough, WoW runs properly on the P-cores without any micro managing via Process Lasso just like it does on W11. SuperPI also selects the best P-core when run as well so CPPC / Thread Director must be working better now with Arrow Lake. I have heard the GPU can sustain 150W and that leaves around 50-60W for the CPU in combined loads. However when running OCCT while I was working on another project I noticed it was down to 180W combined load after a while. It also was draining the battery (12% over the 1 hour test) so the 200W advertised really is not sustainable or good for battery health. I am hoping the "Optimized" performance mode is one where it keeps limits out of the battery drain range.

That a pretty good price for the config. Mine is 285HX, 1x16GB CSODIMM, 500GB Gen4 SSD, RTX 5000 Blackwell, QHD+ with 8MP camera, 3year Prosupport. It was about 5100USD before taxes. I upgraded to 2x24GB 6400 CSODIMMs and will likely get a 4TB SN8100 as a boot drive soon. I will note this machine does not support regular DDR5 SODIMMs - fails to boot with an incompatible memory error. Going forward CSODIMMs should be better but right now we only have them with JEDEC timings which are not quite as good as the Kingston Fury 5600 / 6400 XMP kits.

I wish they offered an 18 inch 1920x1200 120hz panel as well. It's a great resolution for an internal panel that matches the dpi of my external 27 inch 2560x1440 displays. Miniled would be nice too I guess but FALD should be off by default as the dynamic contrast ratio really messes with productivity apps. It's nice this year the 18 inch feels like a flagship model again. In the past it seemed like the Precision 5770 and 5690 were the favored devices and had better engineering albeit at lower overall power limits. I have not seen Mano G post about these yet but I think it's a model to be proud of!

How is fan noise at idle? Does the profile have greater hysteresis so fans do not spin up/down quickly as load spikes occur? I would hope that now we have a very large vapor chamber and cooling capacity it can absorb these much better than the precision 7780 did.

Another thing that interested me about the Dell Pro Max 16/18 Plus is that its USB-C ports are modular - so if they wear out it should in theory be a much cheaper spare part instead of a complete motherboard. 275HX runs pretty well at 55W with the 5090 mobile at 95W. Its pretty quiet operation for a 16 inch at 150W combined load. With the 2025 Intel Uniwill IDY you can tune its GPU between 95W - 175W so its easy to come up with a comfortable profile and experiment to find the best performance on the curve. It also helps to boost D2D and NGU clocks but I am unsure if that can be done on workstations as they are usually very locked down. Undervolting is less of an issue this year so at least we do not have to worry about that.

Well for me the Pro Max 18 Plus stands out from a performance perspective. Having access to full 175W GPU in a mobile workstation was previously not offered from any brand. Its also going to stand out a bit with memory latency as it does not have the usual 2DPC SODIMM limitations. Finally this year it has a vapor chamber and more cooling capacity that is closer to what you can get from a high end gaming laptop. So far the single review and user reports about it seem promising. My order should eventually be delivered. I think it is currently clearning customs into the US which is pretty backed up right now. Eventually we should have more user reports and reviews of the Zbooks and Thinkpad. It will be easier to compare them at that point. I would say if they stick with the same keyboard as the Thinkpad P16 G2 then it would likely be a good choice if you were doing lots of typing.

Interesting. I still have my X370 as well. It's a version purchased from System76 their open source firmware. I also had the speaker audio distortion issue and found it to occur when the Nvidia GPU was over 80C. I could try that quality setting too. I fixed my igpu issues actually by swapping to a 1920x1080 144hz display. It also helped my Linux experience as it removed the need for any scaling. It still runs very hot under load even with a single SSD and only single rank memory. I wish it were as thick as the x170.

Even in the USA getting an order to go through is a pain. I have had two quoted orders cancelled for no explaination. It seems they do not want to sell a machine without a preinstalled OS. So hopefully this time around it will go through. There is now a video unboxing / review of this model as well. I have not completely watched it but so far looks good. We might finally have a workstation that can stay decently close to the current median similar gaming tier results.

Well the new Aurora effect is now just a slow cycle through blue and purple so it is not as bad as previously when it was the complete rainbow of colors. That being said, static by default would be better and all other RGB zones disabled by default would be better. I looked into the service manual and it appears that the fan RGB and lid logo RGB do not have individual cables so simply unplugging them is not possible. Its a shame if this is a play to force people into control applications ridden with telemetry. The Raider 18 I am sure has rainbow RGB as it did last gen. Steelseries GG was a poor experience. I do not understand why these apps still exist as W11 now has baked in RGB configuration with a properly conforming driver. Provided an open specification would be great as well to assist Linux drivers to be developed for configuration without reverse engineering. I have also had some issues with stability on this Area-51 18. Getting Video TDR and Error 153 driver resets / crashes. I was using the 577.00 Studio drivers so not sure if those are still problematic. Exact same configuration with WoW so I know it is not a game client issue with 5090M / 5000 series GPUs. I was able to get SREP to work and set NGU and D2D to 30x. It seemed to freeze when applying changes but HWInfo64 confirms the new clocks. Sadly memory latency is still in the ~110ns range. It really needs XMP to be competitive with other models.

I would say the same about the AMD models. For a while there I had the Clevo NH57 which actually ran fine with a 3950X installed and CCD1 disabled. It was much more efficient than any of the other 8-core CPUs and was also hitting DDR4-3600 with the 32gb B-die kit. I think my Alienware 18 may be one of the ones with a poor CPU paste job as its reaching 100C under load. The GPU stays under 80C which is fine although the palm rest temps get up to 105F so its kind of warm to use. I have gotten used to being able to tune almost everything on the Hydroc G2 including GPU TDP from 95W to 175W. Having something that can do less feels not as nice. I guess if a default profile happens to be what I want and comfortable to use then its fine. The MSI Raider 18 would have the exact same issue with retaining RGB along with Acer. Its a shame they treat it that way and as it is only Clevo and Eluktronics seem to have fully configurable RGB including boot override. I am surprised yours goes up to 175W on the 5070ti. I thought those were limited to 140W including boost.

Started testing out the AW 18. It came with Sunon fans that are not whiny which is nice. I agree the pitch is improved and the noise levels in general. I can also have this setting on my laptop stand without it causing whine or a pitch change which is much better than M18 R1. Its definitely a better air cooling solution than the Hydroc G2. The RGB was Aurora by default and overriding to teal still does not set it as a boot effect. Ideally I want no RGB on any subzone by default (may have to unplug the mobo connectors) and white only on the keyboard. I could even live with solid teal everywhere but it seems like the RGB controllers don't have the few KB needed to store a profile to memory... Installed the Kingston Fury XMP 6400 kit. It booted at 4800 but after enabling XMP it was not booting at all. I have heard that SREP still works on these so maybe manual tuning is possible. It will be painful though as not even a RTC reset is recovering from these memory brick scenarios. There is supposed to be a validated ADATA 7200MT 2x16GB XMP kit coming for these but I cannot find any info about it other than a part number in a support document. Its a shame these still ship with E31. This is a perfect example why I think they should ditch it and use PTM7958SP, just too much risk of it leaking through the barrier. I would certainly be fully removing the board and carefully replacing it before it became an issue. I still hear reports of wide temperature variance on these new models which likely is from poor QC with E31 application.

Yeah mine came from Best Buy for $1k before a few gift cards and rewards I applied to it. My first goal will be to get it setup to Mine and Herb which should only need interact with target, jump, descend, and single button assistant DPS, form stance switch. Hopefully the keybinds will coexist with keyboard + mouse usage even if I have to dedicate a bar to the controller buttons. For questing its going to be more work as the addon has some kind of utility bar that I think is suppose to auto-bind quest items as needed. I actually used to have a similar addon when I was multiboxing that would let me trigger the same quest item on an entire team at the same time via a keybind slot. -------------------- The Intel Hydroc G2 does stutter when switching characters, during heavy encounters or just flying around Dornogal. I think its either addons, using Optimus mode or maxed out settings. I also have to use XTU to apply the NGU overclock after Windows boots which is not automated so I often forget to do so. Maybe an X3D could offer better performance here and this generation has higher PPT along with better thermals due to the cache location.

@electrosoft Got the little Claw 8 setup with WoW on the stock install, performance is pretty impressive so far! It holds around 108fps at your testing spot near the Tazavesh entrance. That is unplugged with 20W/19W PL1/PL2. ConsolePort (the addon to streamline using the game with a controller) needs a bit of setup so I just hooked up a keyboard/mouse to test. Also have Amazon delivering a screen protector and case for it today and will swap to a 2TB WD SN770m along with a clean install of W11. For fun I ran AIDA64 on it and memory latency was 96ns, better than most Arrow Lake HX I have seen! So maybe the LPDDR5X is doing ok here. In this case the device has 32GB soldered which is sufficient and the form factor does not have space for SODIMM or CAMM. Eluktronics has also posted their 9955HX3D laptops for sale, but only in pre-built configurations due to memory compatibility issues: https://www.eluktronics.com/HYDROC-16-9955HX3D-MLED-5090-32G-2T Hopefully once Premamod is available they can do a proper Intel vs. AMD comparison with both systems tuned. My guess is the HX3D will do better than Intel in performance but have worse battery life. I wonder if it would consistently have better performance than the 275HX during world bosses / raids / busy Dornogal. From your positive testing with the 9800X3D it seems like it very well could. I even get a lot of stuttering upon initial login while switching between alts for profession activities and it would be nice if it handled that better as well.
