Corsair Dominator 2048MB PC8500 DDR2

Answer 1

Dominator has Corsair’s latest high performance heat sink with Dual-Path Heat Xchange (DHX) technology..
Performance of these modules incorporating DHX can be further enhanced by using the optional Dominator Airflow Fan, for even more cooling and protection.
Only useful if you work your machine very hard with graphics intensive apps or games.

Answer 2

It relies upon on lots of factors you haven't any longer instructed us (such because of the fact the latency of the memory, what motherboard and CPU you have, and what clock velocity you have them working at). yet maximum probable the version would not be that significant. quicker throughput memory frequently has larger latency (in terms of clock cycles) which cancels out a number of the convenience. the two,000MHz memory isn't 25% quicker than the a million,600MHz memory, it particularly is going to in all hazard be 5%-10%. which will translate into ordinary gadget overall performance ameliorations that are negligible. in certainty, they would be swamped via the overall performance effects of the style of DIMMs you employ. for many motherboards, 2 is optimal.

Answer 3

They are almost identical, except the second one, the 'Dominator' has heat sinks. Might be a liitle better if you your environment is warmer or your pc is in an enclosure.

Answer 4

the dominator has the heat sinks. keeps it from overheating better
