2GB Corsair 1800MHz DOMINATOR CL7 DDR3 Memory ReviewTue, Aug 21, 2007 - 12:00 AM
Under The Heat Spreader
The Corsair 1800MHz CL7 memory kit is available in 2GB kits. If you want a 4GB memory kits, which is nice for those that have already begun using Windows Vista as their primary operating system you’ll need to look at the 1600MHz TWIN3X4096-1600C7DHX G memory kit (which is $1,057). It should be noted that the SPDs on these modules are programmed to JEDEC standard latency DDR3-1333Mhz timings of 9-9-9-24 2T at 1.5V, so one has to manually set the timings to 7-7-7-20 2T at 2.0V in the BIOS to properly install and operate this kit. To reach 1800MHz on the memory the Front Side Bus (FSB) must be set to 450MHz and the proper memory divider selected, so if you are thinking of purchasing this kit of memory be sure to understand your system must be overclocked to utilize the full potential of this kit.
- Memory amount: 2 x 1024MB

- CAS latency: 7 clock cycles
- RAS precharge: 7 cycles
- RAS active to precharge: 20 cycles
- Dual-path Heat Xchange (DHX) heat sinks for thermal diffusion
- Latency: 7-7-7-20 2T
- Power Required：2.00V
- Lifetime Warranty
With the Dual-path Heat Xchange (DHX) heat spreaders removed the Micron D9GTR memory ICs can be easily seen. This is where the magic happens and while it may not look that impressive these little ICs will bring joy to overclockers around the world. By looking up the FBGA code, I figured out that Corsair is using ICs with the part number MT41J128M8BY-187E:B in these modules. According to the Micron website these parts are still sampling and not in full production.
Now that we know what memory kit we are looking at today and the main features, lets take a look at stability testing.
