Heya everyone. I just received my KK266-R (version 1.2) and 1.2 ghz 100 bus unlocked cpu and it appears to be working fine. I have gotten the bus speed up to 150 so far. I haven't installed my os yet so I will post more info in the next few days. I bought the mobo at KDComputers.com as well as a taisol heatsink. I received them in 5.5 days with ground shipping from time of order. With all the bad vibes being tossed around in the forums I thought I would share that not all the 1.2's are faulty and that at least 1 will manipulate the 1.2 ghz 100 bus cpu properly Another point I would like to mention is I don't understand why everyone uses that 60mm 7000 rpm fan on their heatsinks. I mounted a 80mm fan on my taisol that puts out 42 cfm and is very quiet. to make up for the increased fan size i made 2 custom mounting brackets out of old pci slot covers and i spread the tops of the heatsink out so the fan doesnt blow any air outside of the fins Seems to work great so far but I will crank the puppy up after I get my os installed. Good luck
