I have an i7 notebook ( lenovo T410 but that should not be important ) my issue is I want to upgrade it. I need more than 4 gigs but I do not really need 8 Gigs.
But since I think mobile processors also use dual channel if I configure my memory as 6Gigs with 2 gigs and 4 gigs chips I would loose the dual channel and that may slow memory access. Is this true? Should I just cough up the extra cash and go for 8 Gigs. I tried to look for benchmarks that compare dual channel vs non dual channel on core I7 or I5 MOBILE processors but came empty handed.
