[kostas54]

My Dell 5570 has  these values :

0x3EEC7                 Option: 32M, Value: 0x1 {09 07 32 05 30 00 01}
0x3EECE                 Option: 64M, Value: 0x2 {09 07 33 05 00 00 02}
0x3EED5                 Option: 4M, Value: 0xF0 {09 07 34 05 00 00 F0}

0x3EF1B                 Option: 44M, Value: 0xFA {09 07 3E 05 00 00 FA}
0x3EF22                 Option: 48M, Value: 0xFB {09 07 3F 05 00 00 FB}
0x3EF29                 Option: 52M, Value: 0xFC {09 07 40 05 00 00 FC}
0x3EF30                 Option: 56M, Value: 0xFD {09 07 41 05 00 00 FD}
0x3EF37                 Option: 60M, Value: 0xFE {09 07 42 05 00 00 FE}
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}

Try set it to 0x3 anyway. See here

Will try.

Do you think I will gain anything setting DVMT from 64 to 128?
