Corsair Dominator RAM is considered good for several reasons: - Performance: It offers high speeds and support for up to five XMP profiles. - Quality: The memory modules are built with premium materials and have a sleek, iconic design. - Cooling: Dominator Platinum models feature Dual-Path DHX Cooling, which not only improves performance but also adds visual interest. - Overclocking Potential: While not the best for overclocking, it can be overclocked further than Vengeance RAM, especially when using hand-picked memory chips. However, it may be more expensive compared to other Corsair RAM options like Vengeance.
