No, it won't work. You need to maintain the GPU's bit width—6 slots mean 192 bits. The only upgrade option is from 12GB to 24GB. However, as of now, I believe the Ada series hasn't been cracked to support such a large VRAM capacity in their vBIOS.

The supported VRAM combinations are hard-coded in the vBIOS. Refer to the GPU-Z entry for confirmation.

 

 

A request from those on this thread—can anyone dump a 7780 or 7680 RTX 3500 vBios that I could try flashing to my puny 5680? I am trying to increase the TGP and 5680 I believe runs with the bare minimum 60w while the 7680 and 7780 have 90 and 115 respectively.

DDR - CAMM - DDR exchange was an attempt to run it by luck, I didn't want to think that I had lost money. I bought a SODIMM DDR5 -5600 XMP.3.0, and I found "4 white and 2 yellow flashes", I thought that this was the initialization of the memory, and I waited for a long time. Then I realized that this was a problem, and I installed CAMM again, and I did this several times, and miraculously, the power button did not turn off when the laptop was on, and I waited for about 4 minutes for the correct initialization.

@Mambucho Forgot to mention additionally, both the RAM sticks work on the top slot nearest to the connector when tested individually but both of them don't work when I connected then to the bottom one. Did you try something like that ? Also may I ask what is the model number of your interposer or where you purchase it from ? Apparently there are 2 models LS-L88BP and LS-L88LP, mine is LS-L88LP

I was also thinking of replacing the camm memories with sodimm memories. Does anyone know which model I should buy or what the differences are? LS-L88BP or LS-L88LP

How big sodimms i can put in my precision 7680??

 

 

@rintalahri bought the LS-L88LP and only 1 slot of the interposer works, other one does not

@Mambucho same got the exact same one form aliexpress. Strange thing is both RAM stick work on Slot 1 and adjust to 5200Mhz but dont work on Slot 2 (4 white + 2 amber), so likely I assume the issue is with the interposer ?

@Mambucho So I bought a second interposer module and same thing persists this time only the bottom slot works (Both RAM inserted individually and tested) whereas the top slot does not work. So confused
