i.bakar Posted 15 hours ago Share Posted 15 hours ago hello everyone I recently bought a brand new Alienware M18 R2 ( 4 days ago) that was shipped back in march 2025 with 14900HX CPU, RTX 4090 GPU and 64GB or RAM from someone who bought it and never opened the box so the box was sealed… I went through all the posts about that laptop here on NotebookTalk and over techpowerup and so far I was able to gather some information… some was very helpful, other was scarry… Based on those information I was able to undervolt using throttlestop by unlocking UV from bios using the video from that like : https://www.youtube.com/watch?v=uzQ6IwbLje0&embeds_referring_euri=https%3A%2F%2Fnotebooktalk.net%2F&themeRefresh=1 by @ssj92 thanks man and because of this i was able to undervolt the CPU by -50mv and increased my stock score on cinabench 23 from 29194 to 31812 ( this is just my first undervolt for this CPU so i am being conservative for my first week with the laptop ) however there is a few questions that I still cant answer yet. 1- the following link mentions 13th and 14th gen intel CPU self destruct issue : https://notebooktalk.net/topic/2380-13th-and-14th-gen-intel-cpu-self-destruct-issue/#comment-49611 I still cant tell if my laprop proccessor is effected by this or no ? is it related to the patch date Q1, Q2 or something else? I also found a post on dell website asking the same question about the m18 R2 that dell answered by saying this issue applies to desktop variant only (K) of the 14900k and not the 14900HX link below: https://www.dell.com/community/en/conversations/alienware/m18-r2-cpu-voltage-problem/66c3a07547effa74c48660a3 2- would I be able to save my throttlestop settings permanently even if I keep AWCC installed so I can run the fans on different speeds without AWCC override my throttlestop settings ? 3- could the 14900HX handle an undervolt to -140mv as the 13980HX can ? or the 14900HX is already runs at lower volt over the 13980hx ? I found a link to a post on techpowerup that shows some stable sittings to undervolt the 13980HX which goes all the way down to -165mv link below : https://www.techpowerup.com/forums/threads/i9-13890hx-undervolting-suggestions.321679/ 4- this question is a bit tricky….. I used to use Honeywell PTM7950 on my area-51m with 9900k with almost identical result to what I got with liquid metal on the same CPU (the 9900k) which was about 9 degrees C below KPX thermal paste , however I don’t know how good the element 31 stock thermal past from dell is compared to normal thermal paste or KPX so I cant tell if replacing the dell element 31 paste will make a huge different to be worth disassembling my new ( under warranty) m18 R2 ? I know the Honeywell PTM7950 is going to be better then the stock element 31 from dell to handle thermal transfer but by how much ? and is it worth it? maybe I will get a lower temps by undervolting over repasting ?
