I just received the chip today. Its a RIWGA 0234. I was able to get it up to 11 x 173 = 1905mhz(completes 3dmark2001se). I have the vcore at 2.08v because thats the lowest i can go when i do an overvolt on my board. I can't complete 3dmark2001se with a fsb higher than 173. I dont think its the cpu because I tried 174 x 10.5, 174 x 10, 174, 9.5, and 174 x 9. Still can't complete 3dmark2001se. I tried 11.5 x 173 but it won't boot into windows. But i feel i can get maybe another 100mhz if i could raise my fsb higher. I have no idea what could be holding me back. I took everything out of my comp except the harddrive, vcard, cpu and ram. Still get the same results. Anyone know what could be holding me back? Check my sig for details.
