Got warranty activated today including the start date being adjusted to my purchase date so its a full three years. Swapped in A-die. It did not want to boot at 3000/3000/2000 with 1050mv VSOC. 1200mv worked but is probably too much. XMP 6000 C36 equivalent timings (and tREFI 16k) at 1200mv VDD/VDDQ/VDDIO but need to stability test.

Yeah, I was definitely surprised to see it. I want to take it apart and swap memory but there is a factory seal sticker in place. Its MSI warranty expires in September 2026 so I provided the B&H invoice and was told I can extend it by two years for $140. However I want to be charged and have the extension confirmed before I open it up. B&H did have an AllState warranty option but those are $500 for two years (no ADH included) and less likely it could actually get repaired if the mobo failed. The stock memory is 2x32GB Hynix M-die dual rank. It actually was not stable at 6000MT JEDEC with VSOC 1.2v and like all of the new OEM ram I have seen is PMIC locked so no VDD/VDDQ beyond 1.1v. I am guessing / hoping the issue is just dual rank is harder on the IMC as the 2x16GB on the 5080 model had no problem running at 6000MT JEDEC. I do know that all of the 2025 and newer Raider and Titan models have upgraded fans with more blades and are much quieter. I think they also tuned the fan profiles though as it seems like the fans are not ramping up and down as agressively as before. Supposedly these newer fans have the same shroud, connector and power spec so they can be installed in the old models as well to improve them which is nice. The 2025 also has a heatpipe to cool the Gen5 SSD which is good.

Yes I did. These are definitely a unicorn spec so it was too rare to pass up. Hopefully it can run the 2x16GB A-die as well as the 7945HX3D did. Maybe eventually find all of the screen assembly parts to downgrade it to 1600p 240hz IPS as well. The 2400p 120hz miniLED is not horrible using Nvidia integer scaling at 1200p but I still would prefer native 1200p or 1600p.

As it turns out B&H had an open box 9955HX3D + 5090 model for $3375. Supposedly that config was discontinued by MSI as they ran out of Hynix 32GB modules (Micron and Samsung have compatibility issues with Fire Range).

I still use my laptop every day at home and taking it with me to work or when traveling. My wife has now switched to either using the desktop connected to our TV or the Lunar Lake MSI Claw 8. Its a shame that Thin and Light dominates the market. I have heard Nvidia prefers those types of designs and could even refuse to supply their chips into something that they deem would go against their marketing direction like the old X170 or GT75. Then we have the BIOS lockdown cartel where even if you have the right combination of hardware you may not be able to tune it. It is cool that they sent those laptops to you for free. Is that a deal through your work? The pricing is getting pretty crazy, especially when you get into these preconfigured models where there is no option for less RAM or SSD. 9955HX3D Raider 18 is definitely a good option if you can find a deal. B&H sometimes has good pricing on open box MSI models if they also have a sale active on the new model. I still think Fire Range is superior to Arrow Lake when it applies to mobile platforms. Not even 290HX Plus can really boost 1% lows up with how difficult it is to run tuned SODIMMs stability.

Mine came from System76, so its got their open source coreboot BIOS and EC. I just switched the GPU subsystem ID over to the X170KM so all drivers install without modding. I never backported NVPCF ACPI code for Dynamic Boost so it always runs at 150W, and I believe one of the display outputs no longer work (mDP maybe) because of physical wiring differences on the SM vs. KM board. The TB3 on the back definitely works as that is what I use all of the time. Oh and I am not sure if the seller on taobao is active anymore but back then I got a set of fans modded from the A51m R2 to work in the X170. More CFM and quieter!

You may be able to get the heatsink from rjtech / sager. That is where I purchased mine. It was around $300 total including shipping. I still have my x170sm with the 10900k LTT golden sample and 3080m. Thought about selling it though to fund some new purchases.

Well in the process of talking about the Raider A18 value I eventually decided to return it. I found a good deal for a used Titan 18 with 14900HX, 4090M and UHD+ 120hz. The build quality is top notch and the vapor chamber is a good boost above the Raider 18 heatpipe solution. The 14th Gen chip does almost as good as the X3D in WoW with some memory tuning. The only thing I want is to do is downgrade the display to either 1600p or ideally 1200p. I reopened my eBay store and am pretty steadily selling off my excess hardware. This week Nvidia released a hotfix driver that addresses DX12 issues in WoW which has been great. A lot of the problems like the screen going black and slowly rerendering everything after opening the transmog window in certain areas has been fixed.

No idea why they started with UHD and later released this QHD option. So far as I can tell the mobile X3D pairs better with QHD than UHD just like on desktop. FHD would be nice but it seems to be paired only with low end laptops at this point. Eventually they should put it on sale. The price for its specs are pretty high right now and honestly not worth it. A few weeks ago I saw the X3D + 5080 + UHD 120hz config priced at $2800 at B&H and there is no reason this should be more than that with its lower specs.

I have a bunch of alts with each profession + engineering (for wormhole toys / etc). I did not really want another 16 incher either, despite Eluktronics offering the Hydroc G2 with 9955HX3D + 5090. This Raider was a higher price as it is being sold for $3299 only at Best Buy (not Newegg, MSI direct or other usual resellers). So far it has been behaving better than the older model. The balanced profile has very good fan noise. It only does sustained 55W CPU + 115W GPU. For higher performance I have a custom profile with all points set to 55% because otherwise the fans just constantly ramp up and down. The RGB controller at some point reverted to the rainbow puke effect on boot, so I ended up having to install Steelseries GG. For a while it was just static red on all zones without any control software which was really nice. This time around I am running W11 Enterprise LTSC IoT which has been great. Sadly the OEM Hynix A-die memory is PMIC locked so no VDD/VDDQ beyond 1.1v. The 5080M has been plenty for WoW at QHD. I would just need to sell the other 5090 laptops as the Raider A18 can replace the function of the Hydroc G2 and Legion 9i G10 both. It is only a loss of battery life which is not a major concern for me.

I am glad that this cache saturation does not seem to occur around Silvermoon Bazaar as I am running around there often with my profession alts daily. Abundance raids felt pretty smooth. I still need to try world bosses and run the raids with it. I made an decent effort tuning the Hydroc G2 with 275HX. I just came to the conclusion that it needs the water cooling addon to go further with memory. Carrying that around with the laptop is not something I want to really do. I actually get better memory temps under load with the Legion 9i G10 as its got the massive vapor chamber to dump the heat generated by the CPU and GPU. Not that it really mattered as the 2DPC SODIMM design limits speed and timings.

I picked up a MSI Raider A18, this one with the 9955HX3D, 5080M and QHD+ 240hz display. The X3D cache is hands down curb stomping the 275HX in WoW. Easily getting 80-90fps compared to 40-50fps in Silvermoon bazaar at the same settings at QHD and significantly better 1% lows. This new revision of Raider A18 is pretty refined as well compared to the last gen. So far no audio system dropouts, no standby or display blanking issues, no problems with dGPU mode switching to iGPU mode randomly while a game was running. The Mediatek 7925 wifi card had some issues dropping the connection with the provided driver but it seems like a newer revision on Windows Update addressed that issue. Swapping to an AX210 is also an option if the problems persist. Delightfully this model has static red by default for all of the RGB instead of the rainbow puke on the Intel Raider 18. Its a shame the 275HX is limited by memory latency in WoW. The 285K does really well paired with good memory but on mobile it is very limited by heat. Maybe Nova Lake HX will help this if it has an on-die memory controller again and/or bLLC.

Yeah not exactly sure how the memory cover is supposed to help temps. I'd be willing to try heatsinks to see if they are more effective. On the legion 9i I get significantly lower memory temps. I think it helps that it has four slots with only two populated so plenty of room around each module. It also has a vapor chamber so there is less heat bleed from the CPU and GPU to the memory. Unfortunately the insyde h2o bios is very picky with memory tuning so any real tuning has to be done in the OS post boot.

Sounds like the heatsinks help. Where did you get those? Mine definitely warm up under combined loads. I think WoW puts more load on the CPU than other games.

How are temps on your dual rank kits? I use the single rank A-die and M-die modules (2x16GB or 2x24GB). I had them tuned pretty decently but ran into heat related memory stability issues when the modules would get up to 85C in combined loads. I do not have the water cooling addon so its probably limited by the air cooling capability. M-die can go up to 8000MT with VDD2 adjusted to 1.2v although I never really used it as I run in Hybrid graphics mode which still has glitches over 7200MT depending on the memory kit used.
