Overclockers Online has posted an article in which they describe how you have to mod your Kyro2 card in order to overclock it to the top
The first mod we're going to do is installing better cooling on the core as well as RAM sinks on the memory chips. Why do we do that? Well, that's simple. Overclocking hardware results in more heat and if we get more heat, the stock heatsink on the Kyro2 chip isn't capable of cooling it down any longer. That's the reason why we're going to install a big Volcano II heatsink on top of the core. I chose attach the heatsink to the Kyro2 core with some thermal conductive glue. You should just put a little bit of thermal grease on the bottom of the heatsink and also a little bit of glue; then press the Volcano II heatsink on the Kyro2 core and hold it for about 1 minute or so. This way, the heatsink will be glued on the Kyro2 chip. So far, so good. You could leave the Volcano II heatsink as a passive cooler, but I decided to equip the sink with a low profile fan I removed from my 3Dfx Cool cooler on my Celeron300A CPU.Read more
