I can confirm that all retail 4GB 2400C11 I documented are double sided... so no MFR
I will say that even if this exists should be banned from this competition because they are much to rare...
Unfortunately more volts made the MB blow up itself and also the CPU
These chips are low leakage to sustain the 5GHz freq on air, so a good FX-8XXX should be better that any of the FX-9XXX
