In modern terms, 2 GB of memory are often considered as a minimum memory size (not optimal) for a generic computer. In their turn, appetites of Windows Vista and modern games stimulate the most active part of users to choose among 4GB memory kits. Corsair web site publishes an interesting performance analysis of 2GB and 4GB kits, which proves that this memory size won't be idle in a number of games already these days. Even if you feel sceptical about corporate tests, you still cannot deny that the tendency to require increasing memory capacities exists. Unused data can be stored in virtual memory, on a hard drive, of course. But multitasking loses much of its appeal, if switching between applications takes some time to swap data.

Another reason to install 4 GB of memory right now (for a new computer) is because expanding memory by adding a couple of modules to already installed two memory modules always has a negative effect on performance. Even if you manage to find an identical couple of modules in future (which is unlikely), you will most likely have to use mild timings, or reduce memory frequency, if your memory system was overclocked.

On the other hand, we know that high-capacity modules initially possess limited overclocking potential (effect of the dual-bank organization), that's the reason why they are not popular among hardcore overclockers. However, 4GB kits guaranteed to work at high frequencies really exist. Today we shall examine a memory kit, which can operate at the record-breaking frequency for this memory size - 1,142 MHz with the standard timings (5-5-5-15) at relatively low voltage (2.1 V) for an overclocker memory kit.

Along with high speed characteristics, Dominator modules are notable for an original DHX cooling system (Dual-path Heat eXchange), which heat sink has a 4-layer design. The extreme layers take the heat from memory chips in a usual way, and a couple of internal layers contact a special heat-spreading layer of a PCB in a module. You can additionally install a plate with fans on the modules to organize active cooling. In practice, however, it's an excessive measure. Especially if a processor is equipped with an efficient cooler, which also blows at components near the CPU socket.

Manufacturer information


Part Numbers

The manufacturer's web site does not explain how to decipher the DDR Part Number. The datasheet on the web site reports that the TWIN2X4096-9136C5DF is a kit of two identical modules with the total capacity of 4096 MB. The manufacturer guarantees stable operation in DDR2-800 mode with 5-5-5-18 timings at 1.8 V as well as in DDR2-1142 mode with 5-5-5-15 timings at 2.1 V. The default mode written in the SPD chip is DDR2-800 with 5-5-5-15 timings at 1.8 V.
