Does anyone know/have experience what are safe temperatures for DDR2 memory chips?
Increasing voltage rises temperature and I don't have any intentions to add own cooling for memory (I target for high performance without much noise) so that would be nice to know.
Multimeter has temperature probe so I can easily measure temperature of them, OCZs even have these heatspreaders whose holes allow measuring temperature nearly directly from top of memory chips.

they are built with similar CMOS technology as CPUs are, but remember that the temperature you measure will be quite a bit less than the actual IC temp. I'd try to keep it under 50c
Got a fan over those memory sticks? No? Well get to it before you kill them
This review mentions something around that:

Anything up to 2.2V appeared to work fine with no cooling issues, but once you venture over 2.2V heat goes up fast. Above 2.2V we would recommend that you run an auxiliary fan with this OCZ memory.
After five hours of Memtest (and 2.15V) chips on upper end of module give 48C.
DDR2-900 modules I have are "officially" rated for 2.1V +-5% (=2.205V highest official) without loosing warranty and it would be logical for manufacturer to have done thorough testing before giving warranty for that voltage if heat can become problem.
