Finally Play got back to me
So basically they are sticking there own brand on stuff that they have no clue what it actually is.
My confidence in play just took a massive noise dive, just glad I've never had any major issues with stuff I've ordered from them up untill this point.
Just replyed expressing my dissapointment on play.com putting there name
on a product they seem to know nothing about.
I'd not of been surprised if they were selling it as just some unbranded ram and they didn't know full spec's for it, but to take some unbranded ram, slap there company name/brand on it without any real clue as to what it is, I find shocking.
Given that running DDR3 over 1.65v on a socket 1156, for any extended length of time, runs serious risk of damageing your cpu, not knowing what voltage this memory is means I'll not go near it with a barge pole.
I'll still probably use play for games and dvd's but I don't think I'll be using them for hardware again.
Not unless the product is well known to me.
But then again I hardly ever get hardware from them as it's next to impossible to find anything on there website unless you are looking for one specific brand & model.
