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. Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...

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 ?

uzi Posted Sunday at 06:40 PM Share Posted Sunday at 06:40 PM @Mambucho want to report back that I finally solved the issue on my 4th interposer, but I belive it was not the interposer but rather the technique I was using when installing the interposer. So what really did the trick was carefully screwing the interposer to the thin connector. Heres the exact step I followed for others who might be in the same situation: - screw the right side but dont screw in fully just until it fits lightly - screw the left side in fully (slightly more than the right side) - screw the right side in slightly more I can confirm that the above did the trick because when I attempted to screw both side tightly it threw the 4 white, 2 amber error and when I did the above step it started detecting the RAMs again. The key is to NOT TO TIGHTLY FIT the screws holding the interposer to the connector plate. Another thing I realized is that the right side of motherboard of the laptop (not the interposer) is sligthly elevated compared to the left which could be the reason that tightly fitting the screws in could lead to some misalignments between the interposer and connector plate. I state this because the same screw sized screw that was able to screw the left side of the interposer was not able to screw the right side for which I had to use a longer screw. Would be curious what others think about this, thanks for all the assistance ! 2 Link to comment Share on other sites More sharing options...

That is because of 32gb was the largest stick available at that time, and dell had no way to try 48gb stick before the launching.
