Phenom II x6 (125w)

Have a Phenom II x6 (125W version) which I thought was supported by a M4A78LT-MLE board. Well, it runs ok but not properly recognised by updated BIOS, need to use F1 to progress boot. So, any recommendations for a mATX board which will support it 'out of the box' would be appreciated.

Other concern was whether or not the M4A78LT-MLE could cope with the heat when machine was stretched. Strangely I inadvertently loaded a 32bit version of Win7 yesterday and PC Probe reported CPU Temp 77degC, but when I loaded 64 bit version today it had dropped to 32! I can disable the F1 key and hope i never get a fan failure, but thast's not exactly professional, and the machine is destined for someone who does high end graphics and video editing.

Ok you can buy the mobo from scan UK link is above, could you give us the complete system specs so we can give you some advice, including case and fans fitted plus cpu cooler.
Haven't finalised the build yet, am waiting to try a SSD to load the OS on, but the case is an Asus TA-721, one system fan, and the CPU fan is the Cooler Master that came with the processor. (CPU temp 37de C @ fan speed 3500 rpm when running a PC Game) Win 7 Home Premium 64 bit 8 Gb DDR3 RAM. All this suggests the current board is coping well, all 6 cores appear in Task Manager/performance monitor, just feel uneasy about the F1 business. Like the look of the board you suggested, esp. USB3 etc.
