VR/VRE. That is the question?

The non MMX is a VR, The VRE requires less voltage.
your mobo must support VRE to use a MMX CPU
Set the mobo to VRE for MMX CPU.
I hope that answered your question.

That's cause all the ppl that work at Micron are snotty nose kids who were riding bikes and playing doctor when the P55C came out. I know because I used to be one. We're all old sk00l here =)

Sorry, btw. But once your problem was resolved, I just couldn't resist the temptation anymore.

Ah, you laugh! But for a long time, I wouldn't turn the pc on w/o knowing which setting was right...then I gave in and fired it up the way it *was* jumpered! And it worked! It had a 166MMX in it jumpered *STD*. But it still bothered me. Soon after, I was running a program in Windows and it dead froze, so I started wondering again, immediately popped a vanilla 133 in, and here I am asking the knowledgeable!

Pentium-MMX uses dual voltage, VR/VRE is a voltage for Pentium classic, It is the way intel call different currents, before they invented numbers, so instead of saying 3.5v they write VRE , e.t.c. (i am not shure i remember numbers correctly). P-MMX uses split(or dual) 2.8v and 3.3V. so, if your m/b don't have that settings, put STD (standard) , and hope the board have autodetect feature (socket 7) .
It works for me.

All i can offer you is the truth. Nothing more.
