what shows seems ok, try looking for everest free edition 2.20, think it will give the 12v as well.

have you tried installing anything with just 1 stick of memory in ?

system works fine with one stick in, i am able to run 3dmark ect with either one of the sticks
but crashes with 2 sticks installed

 

[Hammy]

have you tried the 2 sticks together in none matching slots ?

No not yet was advised not too

i will give it a go later
