I believe I have an R350 core

thats what the last program I tried said. For some reason Radlinker wont even let me overclock my card, it says it will reset to the new settings, I reset and its all back to default again. I am guessing this is the protection on the card, I read somewhere on here about R350 cores not letting you OC.
I was thinking about softmodding the card to an XT via a BIOS flash. The thread of interest in the sticky seems to point to nowhere. Any info here?
Is there a program I can use to give me live statistics on my cards temperature? Nothing included seemed to be able to do that.
I planned on getting that Antec VCool for my card so that it doesnt overheat when/if I overclock or softmod, is it good?
Thanks for the help everyone

EDIT- The card is the 256 MB one not the 128 MB. Retail ATi not sapphire.
