need to find that quote again... "stupid high"

I honestly have no idea why they have the stock voltage set so high, it should be 1.2V at the most really...

Yeah, 1.25 was enough for 1250mhz on my former Giga 7970 oc rev 1.0 lol
post #32394 of 38704
yeh ... and since i turned it down its worked real nice all day
post #32395 of 38704
lol... I tested 3 7970 and none got stable above above 1200 with 1,256....I'm really unlucky

the best I found was a card doing 1100 at 1.175

I'm using it with 1243 vddc , but hwmonitor shows it as 1256...but not real.

post #32398 of 38704
mine can do just 1.25v --- 1200/1600....but with 1.381v(1.34v real) can do 1375/1820 smile.gifcheers.gif soon it will come 290x, will see what can do those card with EK waterblock biggrin.gif
post #32399 of 38704
I finally took the plunge with the Glacer 240L...so I'll be saving for 290X + EK block as well. biggrin.gif

mine does the same thing with hwinfo64 i thought vddc was gpu voltage but its always 1.219 while my voltage is higher or lower in MSI AB. it used to scale down with gpu core clock and memclock at idle aswell. now at idle my memory clock never decreases and my vddc is always 1.219. I dont know what happened i think i broke it?



could it be because i added a second monitor? I never really looked at it after that until i realized it wasnt underclocking mem anymore, noticed idle temps went from 25ish to 50ish when i hooked it up though.
