OCZ PC3-10666 Platinum Edition

DDR3-1333 Speed and Latency Shootout

Like Kingston, OCZ wants to appeal to the largest group of DDR3-1333 buyers by offering multiple models. Unlike Kingston, the "lesser" kit supplied by OCZ actually represents the company's midrange parts, with the same CAS 7 timings as its competitor's high-end parts.

That's right, price shoppers will find an even cheaper Gold kit from OCZ, but the firm's midrange Platinum Edition provides timings of 7-7-7-20. These are not just rated timings that require messing with BIOS to achieve, but are also found in the SPD values of this part number OCZ3P13332GK dual-channel 2 x1 GB kit.

But this is where things get a little strange; OCZ's Platinum Series is actually rated to run its full performance values at 1.70 volts, yet its SPD table allows these timings to be set at 1.50 volts. OCZ is one of the companies that historically have provided modules that simply weren't bootable on some systems because its SPD values were too tight to operate at a motherboard's default voltage (1.50 volts for DDR3).

The great news is that our modules were able to operate stably at full-rated timings without manually increasing the voltage from motherboard default 1.50 to OCZ's recommended 1.70 volts. This was true for both our Gigabyte and Asus motherboards.

An SPD value of 761 MHz (DDR3-1522) at 8-8-8-23 timings provides extra room for new overclockers who are not yet familiar with manual changes, while SPD values for 571 MHz and 476 MHz translate downward to DDR3-1066 and DDR3-800 for lower FSB processors.
