I have a Prestonia Socket 604 Xeon and a Tyan motherboard that will take 2 Xeon's.

The detailed spec for the CPU I already have (from CPUz - the CPU has a heat sink on it) -
Family F
Model 2
Stepping 7
Rev. C1
Voltage - 1.456

The voltage fluctuates, sometimes it reads 1.440.

I think it's an SL6GD, sort of by process of elimination from looking at the Chiplist web page.

The one I'm thinking about combining it with - I've been waiting about 3 years
for the prices on these to come down -

Model SL6VL

I look that up here
http://www.chiplist.com/ChipList2/tree3f-s_spec_stepping_code-SL6GD--/

... and I find that the SL6VL is a 1.50 Volt D1 stepping.

THE QUESTION -
* is it bad Xeon-fu to mix a C1 stepping and a D1 stepping in this generation of processors ?
