Hi friends,

can you help me anybody with underclocking GPU-RAM to 700MHz in bios for HP4720s? Default clock for GPU-RAM is 800MHz, i need only 700MHz for 3D and 2D, thank you very much.

GPU: 216-0774009 (old GPU is 216-0774207)
GPU-RAM: 4x Hynix H5TQ2G63BFR 12C

Reason for my modification is, the GPU-RAM on 800MHz is nonstable, but with 700MHz is 100% stable.

Thank you for your help.
