i have an gygabyte radeon hd 7870 oc 2gb card

http://www.ebuyer.com/363523-gigabyte-amd-hd7870-oc-1100mhz-4800mhz-2048mb-256-bit-ddr5-fan-2-mini-dp-gv-r787oc-2gd?utm_source=google&utm_medium=products&gclid=CMHnx9yN8roCFfMdtAodHnUATA

ive just seen a post on a website saying a guys stock volts on his is ( stock is 1219 mV )

my card standard is 1169

should they be diffrent?

yeah stock volts can be different based on chip quality and leakage. thats why manufacturers bin chips. its perfectly normal.

so in theory i should be able to up the volts and push my card further then?

i think you should first try 1150 mhz and then 1200 mhz at stock voltage. you might not need to increase voltage. if card is not stable then increase voltage . give it a go. thumb.gif

try 1200 mhz at 1.25v. if it still crashes just leave it at 1150 mhz at stock voltage. there comes a point when pushing voltage a lot for a meagre clock increase is just not worth it given the extra power and heat and noise due to the higher voltage.

Reference cards typically have different stock voltages dependent on ASIC leakage to target the same TDP at the same clock speeds.

ive managed to get it stable at 1200 on the core and 1350 on memory at 1219 volts. well at least i hope so.

going to leave it at that for a while see if i get any crashes or stuff.

but looking at it so far theres not that much if any fps increase

just my GPU usuage has dropped so i will decide if it actually worth it once i go and tweek some in game settings
