Official ASUS X38 Boards: P5E, P5E3 - Info/BIOS Thread

[TKC]

0502 do not like my RAM as 0501, 4:5 and 5:6 divider won't boot still exist no matter how low FSB is.

While regarding the issue of CPU Q-Fan do not work, finally I realize that P5E Q-Fan only support PWM Fan

I installed Intel OEM 4-pin PWM CPU Fan and it works very well. But if Asus supposed to do this why don't they mention a single word in the user guide to let their customer know about the limitation? And it's also quite odd if Q-Fan can control 3-pin Chassis fans but leave CPU fan alone.

Just saw another thread of P5E MF saying FSB/DRAM divider problem is linked to Transaction Booster setting in the BIOS, so I tried it by changing it from Enable/0 to Auto and that resolve 4:5 and 5:6 problem on 0502! boost up my oc from 400x9/3.6G/PC8500 to 460x8/3.68G/PC8832 with the SAME Vcore/Vdimm Now there is no reason for me to flash back 0107 anymore.

So if you have divider problem, set TB to Auto or just disable it may help.
