running 158mhz w/ 2.6v vdimm.... rolling along just fine... i will run my pc a while with only one stick as i really like the 2000+ sign in the bios bootup and the extra 267mhz i got out of getting rid of one of my modules... it posts upp to 180mhz bus with 2.8v vdimm also....
but my cpu doesnt like those speeds
