blend will fail if your not using 2 matched pairs of ram
or 2 diffrent part numbers hidden in the SPD table.
my ram had same part numbers on sticker's but cpuz showed
them to be diffrent.
i found my orthos problem at 400 fsb was defently caused by
my ram

notice they have two diffrent part numbers and two diffrent timings:nono:
BTW the memory will pass memtest all day long
but always failed orthos blend withing 10 minutes

now i opened up my other set of ram since i bought 2 sets just incase:)
set 400 fsb x 8 mulitplyer Ram now @ DDR 800 as this was defently a matched pair.

looked good so now upped fsb to 425 and DDR 850 up the vcore to match FSB
and done blend again.

as you can see my problem was RAM as it also failed prime two
even though it passed memtest.
