If i cant get that spd im looking for i gonna modify oryginal one.
Theres nice page with all bits well described.

As You can see - there is possibility to write own spd by editing values to match higher timings if You need it.
Im gonna try with thoose 53E and then 667 soon.
Still im bit aware of putting mem into working comp.
Ofcourse it isn't risk free, but as long as you put the memory STRAIGHT in it should work fine, still I can't guarantee it though.

Just try to find somebody / some shop that has compitable hardware to flash your memory in, safest method by far

The fact that I had to hotplug because it didn't booted anymore with the other SPD....
