Hi All, I've been doing a lot more analysis on my XPS 15 the last few days and have been running many tests both before and after a LM Conductonaut repaste. Temps for the CPU (as mentioned by @iunlock ) are pretty good but I've noticed an issue in game also potentially noticed by Doug from ultrabookreview here: http://www.ultrabookreview.com/14875-fix-throttling-xps-15/ The issue is when gaming on a particularly demanding game. Theres no doubt the GTX 1050 can handle BF1 at high settings on 1080 no problem at 50+ FPS consistently and for the first 5 - 10 mins of playing you will notice just that. HOWEVER, after a period of time (so long as you have CPU temps cool enough) I noticed that my FPS in game would suddenly drop from 50's to low 30's! After much annoyance and investigation I think I've found some evidence to suggest whats going on. If you look closely you can see many things for the XPS: The CPU clock is rock stable on all four cores at 3.4GHz suggesting that the CPU is working well and is being sufficiently cooled and powered to maintain those clock speeds. The GPU clock seems to be cycling around values from 1900 down to 1000/1200 then back to 1900 again I can confirm that in game when the clock speed is 1900 I get a nice stable 50+ FPS in game but when the clock speed is 1000 to 1200 (I.e. being throttled), the FPS drops to low 30's FPS. Conclusion? It's related to the ambient temps and NOT the GPU temperature because as you can see from the graphs, Whenever the Ambient sensor hits 98C the GPU throttles (to 1000 to 1200) and whenever it drops to 78C the GPU clock is enabled to go full speed again (1900). So therefore I conclude that this must be one of the VRMs / MOSFETs from iunlocks diagram.... But which one? Now begins the fun task to figure it out and to stack 6w/mK pads on it until the correct one is cooled. I already started this to begin with: But now I will stack each one to the metal chassis until it can be cooled (as per the advice from Douglas from ultrabookreview) I'll keep you all posted with the results!
