Software memory adjustment on 2900XT?

Yesterday I read this on The Inquirer yesterday:

'Biostar's V-RANGER feature allows users to control the voltage figures for both GPU and the RAM, something that was achieved only by non-publicly released utility for the ATI Radeon HD2000 series.'

Does anybody have any information about this 'non-publicly released utility' for ATI cards?

I dont know if itll work for ATI, but here you go

No, the quote mentions a 'non-publicly released utility' for adjusting the vgpu and vmem of ATI 2xxx series cards and I wondered if anybody had any information about it.

Thanks anyway though. :
