Closer Look: OCZ DDR3

DDR3 isn't much to look at. Sure, you can dress it up with shiny metal heat-spreaders, but it's still just a small printed circuit board with DRAM ICs soldiered to it. But I must admit, OCZ always finds a way to make their modules stand out as unique and appealing.

For anyone not familiar, DDR3 RAM uses a unique 240-pin DIMM (Dual Inline Memory Module) architecture. This new design does not allow for backwards compatibility, and it offers many design differences from the DDR2 predecessor it replaces. First revealed in dual-channel kits for the Intel P35-Express platform, the latest iteration is offered in triple-channel kits for Intel's Core i7 / X58 Platform.

Because of the odd number of modules included in a triple-channel DDR3 memory kit, OCZ has decided to package them into separate containers. This isn't the most economical packaging system, nor is it very 'green' by today's standards.

Similar to other memory kits they produce, the 6GB OCZ3P1600LV6GK kit re-uses the platinum heat-spreader familiar to the dual-channel series. Unlike some of those dual-channel kits, the newer triple-channel kits are much slower in speed and use lower voltage. OCZ most likely selects kits from their inventory that can achieve decent operating speeds with acceptable latency, and adhere to the low-voltage requirements of the Core i7 platform.

Because triple-channel kits use a much lower maximum voltage (to avoid Core i7 processor damage), extreme cooling is unnecessary for these modules. Under stress, the OCZ 6GB Triple-Channel 1600 MHz DDR3 was barely warm to the touch. In the next sections, we see if it really makes much difference how fast a triple-channel kit operates... as we compare the OCZ3P1600LV6GK memory kit to several others.

# my ddr3 ram wont lock into motherboardtheodore hastreiter 2010-02-18 13:26
i just bought some ocz ddr3 6gb sticks and i cant seem to lock them into place it seems the notches are to high my motherboard is a asus m4a77td pro and my ram is OCZ 6gb OCZ3P1333LV6GK DDR3 PC3-10666 1333 can someone plz send their opinion to my email.

# Without O/C how can we get better performance with PC12800 ?bsquare 2010-11-29 23:59
I've read that intel i7 (particularly 920, 930 ... 950) was limited to equivalent of PC10600.
So without overclocking, HOW can we get better performance with PC12800 (compared to PC10600) ?

Best regards

The primary benefit to the higher memory speeds is the ability to keep up with the CPU as it is overclocked, IMHO.

Ok; but without O/C ?!

The motherboard manufacturers have been more accomodating than Intel, and have provided additional multiplier settings on most enthusiast products. This allows you to run the memory at the higher speeds, even though Intel never designed the CPU/Chipset to do so.

Hum ... so YES without overclocking, we can get better performance with PC12800, against PC10600, thanks to motherboard technology; right ?
Is it still true with PC17066 ... and PC19200 ?

One of the best demonstrations of what you're asking about is here on this site, this 2500 MHz kit that was tested recently.

Thx for information but it confirms overclocking is needed to benefit from such higher frequencies.
My question still exists without overclocking; what is the higher frequencies we can benefit with an core i7 950 ?
