PHVM_BR Posted October 23 Share Posted October 23 1 hour ago, Chalybion said: 6-core CPU max power is 60-75W, and for the 15" precision, max GPU power is 80W. So a 180W adapter is plenty. 240W adapter is only needed for 17" models (w/ 110W GPU), or if overclocking an HK-variant CPU. The Xeons are supposed to be a binned version of the equivalent i7, with additional support for ECC RAM and vPro. So the Xeon theoretically has better silicon quality - so theoretically less voltage is converted to heat at the same clock speeds. You may not see an appreciable temperature difference. FWIW, I've undervolted two Xeons in these laptops; one was 100% stable at -115 mV (both core and cache), the other stable at -120 mV. I'm not sure how that compares to the i7s. I had an i7-9750H for four years, and it was completely stable at -125mV/-215mV for cache/core. With Speedshift = 0 (Windows power plan set to High Performance) I could maintain it at -135mV/-225mV. i7, i9, Xeon... I think it all depends on the silicon lottery. I agree that a 180W charger is sufficient for i7 (6-core) versions. Link to comment Share on other sites More sharing options...
Nrml Man Posted October 24 Share Posted October 24 Thank you guys for answers.I think i need not to bother about other cpu,my 8750 is fully enough for today.Only i'll change gpu.Do you know a difference between delta and sunon fans,what are better?

Chalybion Posted October 25 Share Posted October 25 Delta fans create less high frequency noise at high speeds. Not a necessary upgrade, but a nice-to-have if you are already taking off your heatsink. They are distinguished by a white plug (instead of black), and no sticker on the fan hub.

Nrml Man Posted Thursday at 03:55 PM Share Posted Thursday at 03:55 PM I received a heatsink for p3200/rtx3000 from Aliexpress.But it came a little curved,and connection holes on gpu not matched by installing.So bad but its not the end of the world,i leave this idea,but at least i changed my Gelid HeatPhase for a fresh Ptm7950 on cpu.I see a little difference in temperatures already,Ptm is noticeably better.Thank you guys for answers and advices,have a nice day!

You mentioned switching to a Precision 7550 VBIOS (~90W). Could you please share the exact VBIOS version string (as shown in GPU-Z)? I want to update my current BIOS. Thanks a lot! or the rom please Link to comment Share on other sites More sharing options...
