0x3EF3E  End of Options {29 02}

 

I changed to 0x2 and got DVMT=64. I would like to set it to 128 but I don't see such value. That means that my laptop can only get up to 64MB?

 

Also , 

should I change this value to max (default is 256) ?

Setting: DVMT Total Gfx Mem, Variable: 0x796 {05 91 44 05 45 05 F4 04 01 00 96 07 10 10 01 03 00}
0x3EF53             Option: 256M, Value: 0x2 {09 07 47 05 30 00 02}
0x3EF5A             Option: 128M, Value: 0x1 {09 07 46 05 00 00 01}
0x3EF61             Option: MAX, Value: 0x3 {09 07 48 05 00 00 03}
0x3EF68  End of Options {29 02}
