One guy that you should definetly get a hold of is AndyOCZ over at DFI-street. He is a rep for OCZ and helps people troubleshoot problems with their OCZ memory. If anyone is going to know, im sure it will be him.
this ram will do the timmings it says on the packaging. I have this same ram on my DFI SLI DR Mobo which runs at cas188.8.131.52 1T with no problems. voltage at 2.8v
