overclocking DDR memory?

I put a stick of 512MB PC2100 DDR memory (generic - no named brand) into a P4 1.6a system. I then set FSB to 133 and the CPU-DRAM ratio to 3:4 ... so the memory is running at 2 x 177 = 354 Mhz! I did not mess with the voltages or anything. My question is ... what is the risk of frying/damaging this RAM if I run the system this way (the RAM is only rated at 133/266)? Do I need to put a heatsink on the RAM? I've been running in this mode for the past few days ... no problems so far. The Sandra memory bandwith scores tell me that my memory is exceeding Rambus performance!

I'm debating whether or not to keep the system this way, or to reset the CPU-DRAM ratio to 1:1 and raise the FSB to 150 ... more megahertz, but slower memory. Any thoughts?
