Patriot is a good brand XLB or XBL i dont know which but there good OCing ram. Nubius uses it and he is a heavy OCer so Patriot is not shit Corsair is a good brand PQI is ok and Ultra well it is crap. OCZ is good.
Patriot XBL is quite good, it uses Samsung TCCD chips. Just ask Nubius. He uses them, and OCing is, well, his passion/hobby/life/any other thing i can think of
