ThinkComputers.org posted a review on the OCZ Platinum DDR3-1333 4GB Low Voltage Dual Channel Memory Kit A quote from the article:

The standard for DDR3 memory is still 1.5v, but most high performance memory has voltages far above that. Many earlier high performance DDR3 modules had a Vdimm of 1.9v-2.1v. It still amazes me that the memory manufacturers were able to make DDR3 memory run at DDR3-2000 and higher at 1.65v. Today I will be looking at yet another low voltage dual channel kit, this one by OCZ, their Platinum DDR3-1333 4GB kit. It runs with timings of 7-7-7-20, at Intels required 1.65v. And of course these modules sport OCZs shiny platinum heatspreaders. Will this memory take my i7/P55 to victory? Read on to see!
