I have 2 sticks of RAM (1G + 512MB), which has the Samsung UCCC DDR ram on it. Both were rated at DDR 333. 2.5,3,3,7 @ 2.5V.

1G was Samsung manufactured PCB+Chips with Crucial Label (got from d44ve)
512MB was Samsung chips with unknown PCB with Kingston label (got it at local store, they have a whole load of these)

I have pushed both to 480MHZ, 3,4,4,10 @2.8V. Both were stable.

I want to know how much more I can push before it craps out. I want to know the safe voltage so that I don't kill those.

Sorry I am still in DDR age.

Thanks.

Really you don't want to go over 2.9v with DDR. With 2.9v I would recommend active cooling though. And for 333 that's quite impressive getting to 480....
