The Viper mamba RAM overclocks well actually so that kit should stand a good chance of reaching 2133mhz if pushed a little harder (The 2133Mhz kit hits 2400Mhz). It's heatspreaders arent that tall so you can get heatsinks over them easily enough
Ahhh didnt know that
Useful info to know though seeing as the 2 nearest have their faults
