7970 OC - What is the common voltage used for 1200MHz ? - Page 3

post #21 of 27
Increasing memory voltage has helped me get almost to 1900 on memory, my Sapphire does 1750 stable on 1.5 in 3dmark. My Gigabyte is much lower only around 1700 @ 1.65. To bad my core clocks can't go over 1210 @ 1.268v in CFX ;/

Thanks, rep +

BTW when did you buy your DCII?

last Thursday and been playing around since biggrin.gif

mine is 2 x 6pin, i dont think it will limit your OC but what will like CPU is the silicon lottery with the GPU thumb.gif

Thanks alot buddy! rep + once more, you really helped me with the info, can you post GPU-Z screenshot or tell me your PN?

Also if you can do one Crysis/Crysis Warhead bench with max out (stable memory oc) and after with stock 8XMSAA, thanks in advance thumb.gif

I haven't installed Crysis for quite some time actually. It seemed from most of the reviews of that card that Sapphire had a decent bit of memory, I was surprised myself at the frequency that I attained. I didn't really want to push higher than 1.68 as I'm not sure what voltage is considered to high for GDDR5.
