Post by: REF on May 20, 2011, 02:02:42 PM

I was looking to buy some 5850's i found this one by gigabyt but does anyone know what their "default max oc" speed is at?
I already ave a xfx radeon 5850's its default clock is 725 and i can only OC to 775.

I don't know if you have your heart set on using Microcenter, but this is a better card from Newegg and will let you overclock better than the one you are looking at:

Site was wrong ;p Core is the same as in 5870, which default voltage is 1.25 and there are numerous tools to increase this voltage.

none of these really help my OP. Also if anyone knows what Power Connectors does it require it seems like there is a typo on the site. i think its suppose to say 2x 6pin connectors can anyone confirm that?

No one can tell you what the max OC is.
Overclocking is YMMV by nature, as no two cards are equal, and no two environments are equal.
You will have to buy it and find out yourself.
