3080 MXM Shunt mod 180w limit

[incendery]

I have successfully modified the shunt resistors on a clevo 3080 card out of an x170km, I installed 20mohm resistors on top of the existing 5mohm for somewhere in the neighbourhood of a 4mohm result (in theory a 20% increase in headroom"

 

due to lacking dynamic boost support in my p775dm3 I was stuck at the 150w limit, it should now be around 180w!

 

I am temperature limited now but will update with performance once my ptm7950 arrives!

 

3dmark timespy result: 13801 GPU score

with a little undervolting I am quite happy with this score despite being on the raw edge of throttling, holding at 1800mhz core through the whole bench

impressive. great scores also.

 

I was wondering what your firestrike score was. do you game? if so do you game at 1080p>?  should be good for a few more years at 1080p/1440p

Firetrike score was 35631 GPU after PTM installation, I'm able to hold around steady boost at 1890mhz under firestrike load while under 60c!

I do a fair bit of gaming at 1080p on my desktop, I'm moving countries in the next month so this laptop will become my main machine very soon.
Should tide me over for a year or so until I rebuild a desktop :)

The benchmarking is getting quite addictive now 😄

maximum GPU temperature of 72c even with the shunt mod and in theory near constant 170-180w power draw during the bench, I am interested in getting access to the i2c bus for the GPU to see what my real power draw is.

Not quite stable, getting some artifacting on the screen with this run so I will have to up the voltage a little bit, but valid score regardless.

 

Very impressed with PTM7950

hmmm I need to redo my changes to boardID in the bios, inadvertently changed the subsystem ID for the audio device and now my headphones don't work 😂

 

shunt mod is still working very smoothly, I will push the memory a little now and see what scores I can hit

(update)

fixed! had one of the wrong values in the boardID file changed, it now works correctly and smoothly

holy hell MXM still exists!? a 3080 no less!!!

MXM is quite dead in the consumer space unfortunately 😞 this is a card from the last true DTR clevo with socketed CPU and GPU (X170KM)

There apparently exists an MXM version of the RTX 4060. Fast forward to about the 10:45 mark of this video to see it:

I want that mxm lol, would make a nice upgrade for the Precision 7510/20 for example though probably too much for the M4800 unless someone makes a custom heatsink.
