7900GT over voltage protection?

[Dihon]

Just want to recap the whole thing from the beginning :
1. Do we need to remove any resistors to disable the OCP ??
( In the beginning there's a post about removing & changing the resistor from 3.5K to 150 % higher, then later we read about removing 2 resistors )

2. How about Vmem discussed earlier in this post ?
My card ASUS EN7900GT with Samsung BC14 after lowering the resistor to 560 ohms, I can bench till 1025 MHz.
But I can't measure the Vmem, I don't have a precise digital Volt meter.
