Anyone Know Where I Can Get This?

I am trying to find some old memory for sale, used or new, don't matter, they do have lifetime if not warranty voided. I am looking for some OCZ Performance Series 2x512 kit, in either PC 4200 or 4400; were the same units but the 4400 was just an overclocked 4200 version. I know you might say, why these now a days. Well simply put, my overclock is stable with this two sticks shown below and I have tried some new 2x1024 kits, but aren't compatible. Going for the impossible 4x512 and see if I can keep my overclock. Some have done it, so I will try.

both are used I would guess

Thanks for the reply, I will look around there more, but those two you linked are platinum series, not performance series.
