Hello to everyone!
Could anyone explain to me something about CM2x2048-6400C4DHX versions?
I'v got a pair of 2gb modules on my desktop configuration (ver. 3.2), and I'm going to buy another 2x2gb kit. I've found same kind of modules, but ver 1.1...
Are they so different or could they live together without problems?

Thanks in advance...

If you keep ver 1.1 and ver 3.2 in separate channels then they 'should' work in a 'Qaud' channel arrangement. Both are 4-4-4-12 2.1v.

Not knowing your MOBO, you may need to increase the QPI/DRAM Voltage and I'm pretty certain that XMP will not work and you probably will nedd to manually set the DRAM Voltage and CAS timings.
 
If it's a problem and you cannot get them to work then post again. Refer to pages 4-16~4-20 of your manual; enter the Frequency, CAS timings, DRAM Voltage per above.

Installation refer to page 2-15; Set1 = A1/B1 an Set2 = A2/B2.
