Like the Title says, I picked up a 152 Opty pretty cheap, Oem chip that was brand new until about 5 hours ago 
The chip in my Sig has served me Very well, but I found it time to try a different 1. I started out at default voltage, and got to 2800 and change with it. 1.425v got me to 2950, and I just upped it to 1.45v for a highest tried 3004 for now.
I'll run it here for a day or 2, with testing inbetween, it is 1 hour prime stable, small ftt's at 2950 and 1.425v, will test later this evening as to total stability at 3000.(passes memtest test 8, and Super Pi 4m so far, didn't bother with test5 Yet as i know the ram is stable).
Ram is running 1:1 right now, no tweaking there yet. Nice chip so far. I figure if I can keep it stable under 1.5v, ( at a higher clock of course), I may just keep this 1, and sell my 148.
I'd tell you what i paid for it, but it would make you sick
Temps at the moment;
Cpu 24c
PWMIC 26c
System 28c ( kinda warm in here tonight ) 27c now
The reason I decided to start a thread on this, is because while I was waiting for this chip to show up, I searched high and low for ANY info as to anyone clocking a 152, and found exactly "1" thread, that was an archive at Overclockers, and believe me, I searched Everywhere.!
I'll update the thread as to how it goes, that is, IF it goes.

EDIT; I'm at 3060 so far now, 1.475v still testing.** Make that 3107 , still in testing mode.**
I really did Not think the chip would go to far, but so far I am rather pleasantly surprised that it is behaving well
