I've quietly cracked 107000 blocks under the team anandtech moniker. My k7-800 and sometimes when its on my brothers p3-800 are under my name, but the other day my k7-800 started doing wierd unknown errors in win2k, like memory not read or something. It hasn't don that in a while, but i dont know if maybe the wear of having my CPU at full load for so long is good. I've had this computer on pretty much 24/7 since august and well i guess i'll keep cracking since CPUs are cheap. But does cracking ever make your systems unstable? Also i'm not even overclocked and it always at 50C. I dont know, anyone else had a unknown error, memory not readable error in win2k?
