Question about Corsair ValueSelect

Thank you all for your efforts...but after the ram's arrived I immediately plugged them in and let them run...!
Everything is running beautifully!!!
Thank you!

Unofficial?
First we need more details about the existing iMac 27'' mid 2010 :
Processor?
existing RAMs Timings (CL etc), Volt
what is planned: keep existing RAMs or replace them?
RAM GB total planned: how much?

Ok...but unofficially it also says that you can increase the memory to 32 gb!
Apart from this, I have also noticed that the Mac can also be equipped with one 8gb and three 2gb....this from a dealer....

No, see

there must be 4x 4 GB (not the same as 2x 8 GB), with 16 GB all 4 slots must be occupied.
