Hi all just wondering whether it would be a good idea to uo the voltage to 1.3v on my 7870 Tahiti LE. I'm aware overclocking varies but I take it 1.3v is usually fine in general?
Currently at 1130/1620 on stock voltage![]()
Thanks

Whats the current voltage?
What software are you using to play with voltage?
Hi, currently using Sapphire Trixx as couldn't unlock the controls in MSI Afterburner. Ran a benchmark and the highest voltage reading was 1.211v but the average was around 1.175v although not sure how accurate this is as voltage is always changing unless I apply the "constant voltage" setting via Trixx
Although not really sure I like the Sapphire software as when I open it the VDDC is 1156 and when I click "reset" it goes to 1225 :s
Of course at idle the voltage is under 1v according to GPU-Z

1.3 sounds a little high then; I'm not entirely sure what is save but 1.2-1.3 seems a rather large jum. I would take it in little steps; 1.225V seems like a good starting place! people report 1.25 - 1.29V for thier cards (TPU reviews for example).
I think running trixx also kills off the power saving states while its in use iirc.
CCC has had good reports form a number of OCers for these cards at stock volt with 20% power boost.
