What's the typical required voltage for 900 MHz on the core? Did a short bit of testing today, seemed to get 875 MHz stable at 1.088v (though not much testing aside from MSI Kombustor for a bit and Heaven benchmark once over), but 900 reverted to stock speeds at the same voltage.

Also, what's typical for RAM overclock? I bought an "overclocked" MSI card that was running reference clocks, so I set the clocks with Afterburner it was supposed to have (no voltage tweak), and it reverted back to reference midway through Heaven. If I only changed the core speed to what it was supposed to be, it ran fine.

Thinking I may have gotten screwed over... D:
