I'm trying to establish if a Dell BIOS mod can UNDERVOLT the GPU on a non-MXM laptop, in my case the M1530 with NVIDIA GeForce 8600M GT. Credit to Apokrif, AndyP, Busykid508 for deciphering the Dell BIOS in the first place. Please can someone explain what can now be altered. Is it that only SLIC tables can be modded, or can CPU and GPU parameters (like voltage) be altered too? If I'm barking up the wrong tree, this site deals exclusively with SLIC mods, I'm posting in the wrong thread or committing some other faux pas let me know because I'm a bit lost.
