Sapphire's Radeon HD 4830 sticks with AMD's reference core and memory clock speeds, giving us clocks of 575MHz and 900MHz respectively.

From what we've so far, almost all AIB partners are opting to use custom cooling solutions in conjunction with their Radeon HD 4830 offerings, and this is certainly the case with Sapphire, who use the same rather fetching cooler recently seen on their Radeon HD 4850 part with custom cooling, comprising of a dual-slot cooler which covers the GPU core while also offering a certain amount of cooling to memory modules.
