7970 sapphire overclock with boost

post #1 of 5
Thread Starter 
Hey so I bought this card off of newegg
http://www.newegg.com/Product/Product.aspx?Item=N82E16814202008

I used the guide here to oc it to

1100 core and 1520 memory and it's stable

Get up to around 68c

my ASIC quality is 59%

vddc is 1.881

Basically i was wondering at this point what i can do to get more out of my card

A little disappointed that i can't oc it more since i've heard that the 7970 can oc very well

Any help would be appreciated

have you tried pushing higher than 1100 mhz ? are you running at stock voltage ? if you are on stock voltage , install msi afterburner and increase the voltage in small increments of 0.05v. try and hit 1150 -1200 mhz. monitor core and VRM temps. core temps below 70c and VRM temps below 90c are advisable. you can set a custom fan profile or increase fan speed to keep temps under control.

Yes im running it at stock voltage and whenever I up the Clocks on either memory or core I get artifacts on gpu tool . I have tried increasing the voltage to 1.2 before and it didn't have any effect.

just wanted to add that i have been using msi afterburner and i have the increased 20% draw

at 98 on bf4 VRM temps are 64c and gpu core 65

you could try higher core voltage. 1.225v and 1.25v are fine as long as core / vrm temps are safe. beyond 1.25v i don't think its worth pushing for air cooling
