it's a 3080. for heatsink, if we compare price vs performance, the home made tshape heatsink at a cost of 47€is the best u can get with decent temperature. then there is the t-shape from viktor for 150-200$. maybe ytour vapor champer is first for performance, but for 400-600€ i would never get that money back. also the x170 has native vapor chamber for the 30xx series so it will be more cheap to sell the p870 and get an x170 instead of spending too much on a heatsink. also for the 40xx series. i wouldnt go for it as that vga doesnt have external power and when first 1070 mxm comes out without external power, almost all of them died after a while.

hi today i finally modded my second heatsink. tomorrow ill assembly all and test. it was not that hard to modify it , and for 47€i think this would be the best heatsink for p870 series....

hi i,ve ordered another of that heatsink some weeks ago. code is : 6-31-P872N-401 and i got it from aliexpress for 49€ ship included. u can find it here: p870km t shape heatsink for gtx 10x0 series. one is for 10 series gtx and the other is for gtx 980 desktop bga. now i dunno if i should cnc the ram pad without heating the heatsink or go full process and maybe attach to my modded heatsink pad ...

my p870km with modded bios and rtx 3080 show rebar enabled.

my p870km with dsanke bios has already rebar enabled.

im glad u had the pads fit perfect. what temperature u reach max ? remember that now is winter time, and lots of 1070, 1080 that were cooled by one heratsing only radiator got killed overtime. with my old 1070 and double heatsink like u i had max temp of 75° even in summer time. card is still working after so many years. u can also unvervolt the gpu. for the 200watt mod if i remember correctly, there is a bios to unlock that power. it should be easy to flash via dos, but u need to find the correct thread.

i have this man

memory thikness is 0,5mm

tnx for posting that ebay modder, ive seen modded heatsink for less then 250€...... ill buy it for my clevo 🙂

multiplyer 47x then voltage offset - (minus) and check if -80 is ok. generally with 9700k i have -80 and 46 on all core. tried -100 millivolt but was not stable. ps: where did u get rtx 3080 heatsink from ? t

an rtx 3080 heatsink for that model made by you would be really appreciated 😄 till now im good with my home made one 🙂

this exact heatsink was used by a russian dude... it reported to have high temperature on full load when only with air cooling mode. that's because it's not made of full copper and it has 2 heatpite each gpu side... too few for better performance. it's on yt..... search for p870 rtx 3080... there are metro exodus test and u can see gpu temperature is really gigh. i talked to that guy on vk and he confirmed heatsink was expensive and he get gihg temperature. for me best performance/price is the other heatsink viktor showed us in this thread. for 100€ my heatsink is not that bad too 🙂 ps: about that 3080 with p870 score that are close or equal 4080-4090.... to get that score, massive overclock has to be done..... if an 3080 mobile score like 4080 mobile..... fair comparison would be compare overclocked cpu, overclocked gpu on both system....

power limit 1 to 135000 , also power limit 2 to 135000. then on processor on bottom of that bios page, put the "-" and then 80mv. try with all core to 4.6ghz.

unless ur under air conditioned enviroment in summer i downclock the cpu to 4 4.2ghz max .... during winter i have 4.6ghz with -80mv. power limit set to 135 watt. more then 4.6ghz must be usefull only for benchmarking .... no real need to daily use a notebook with such high cpu frequency in normal gaming. this is all my opinion about longevity of notebook.

what heatsink are u going to use for the 3080 ? good news ur getting picture now 🙂
