The difference is 16Gig (4 x 4Gb) vs 4Gig (2 x 2Gb), which could be pretty substantial--that is, if it matters at all: If your compute-intensive applictation runs in say 1Gb, but with a lot of loops (the compute part), then having 16 Gig is a waste. But if your compute part uses (or could use) a great deal of memory, (eg random access on a large (16gb+) memory mapped file, then the 16Gig will make a big difference. But we don't know if this is the case. And "compute-intensive" doesn't necessarilly mean "memory-hog". There are plenty of numerical algorithms that run with a relatively small fixed amount of memory, but require fast CPU to memory access, because memory locations are being repeatedly updated or read. We don't know if this is the case.The correct choice depends on things we don't know, yet. --Dean
You just found a big type on my end - thanks - Corrected question as follows: What is the speed difference between 1 x 4GB vs 2 x 2GB modules? Thanks. Scott _______________________________________________ bblisa mailing list [email protected] http://www.bblisa.org/mailman/listinfo/bblisa
