Today we'll look at OCZ's Platinum DDR3 PC3-14400 dual channel memory kit.

Now that the P35 chipset and DDR3 have been out for a while, memory module manufacturers are beginning to deliver high speed modules aimed at enthusiasts; and finally, DDR3 prices are starting come down.

Memory technology moves quickly; and between the time we received our test samples and today, OCZ has re-qualified the modules for faster 8-8-8-24 operation, shaving three cycles off tRAS (row active time) from the 8-8-8-27 that our modules were labeled for. We tested at the 8-8-8-27 timing indicated on the modules.

As an aside, all this high-speed DD3 memory coming onto the market heightens our anticipation towards the upcoming release of Intel's next chipset, the X38. The P35 is the followup for the more mainstream 965P chipset, and the upcoming X38 is the replacement of the high-performance 975X chipset. Past experience with the difference between the 965P and 975X chipsets suggests that the X38 will have better memory performance than the P35 based motherboards that we currently use for testing.


Let's see what OCZ has in store for us..

Test Setup   

For this review, we used the excellent ASUS P5K3 Deluxe WiFi; but here is a list of components that were used for some of the other tests.

Hardware for testing of the DDR2 memory:

Hardware for testing of the DDR3:

Software & Benchmarks Used

Here is a list of the tests performed:

Video drivers used were the NVIDIA ForceWare version 93.71 package.

We made the test systems as similar as we could, other than the memory - so it should give us some very interesting results!


As we would expect, the OCZ Platinum PC3-14400 performed a little worse at 1800MHz than the Super Talent DDR3-1866, however once it was overclocked to 1868MHz it tied the Super Talent modules.

One thing is certain - the performance of the tested modules at 1455MHz and up is excellent.

RightMark Read

Once more, the Super Talent performs about 4% better at 1866MHz than the OCZ Platinum PC3-14400, however once the OCZ was overclocked, the performance is virtually identical to the Super Talent.

RightMark Write

I think we all knew we would get the same result here :-)

RightMark Bandwidth

At its stock 1800MHz, the OCZ Platinum PC3-14400 is slightly slower than the Super Talent at its stock speed of 1866MHz, however once the OCZ is overclocked to the same data rate (with a slightly slower tRAS) it almost catches the Super Talent.

RightMark Latency

The extra three cycles of tRAS hurt the OCZ PC3-14400 on the write bandwidth, however it still does very well. The OCZ web site now shows these modules as running at the same tRAS=24 setting, and with that setting, the OCZ would have tied for the top result here.



At the stock 1800MHz, the OCZ Platinum PC3-14400 does well, but it is outpaced by faster data rate test results; however when it was overclocked to DDR3-1868, it took top spot, even beating the Super Talent DDR3-1866!

Doom 3

The OCZ Platinum does well here again; the stock result is understandably lower than a higher clocked stick; and when overclocked, the OCZ Platinum PC3-14400 took top spot!



I was able to overclock the OCZ Platinum DDR3 PC3-14400 dual channel kit by another 68MHz - I know, its not much, but we have to remember that these modules are essentially overclocked from the factory, and getting an extra 3.78% speed out of such high speed modules is not bad.

I was pleased that I could reach 1800MHz at the stock settings (including 1.95V for vDIMM); and I was not at all surprised that I had to bump some voltages to reach 1868MHz. To reach the overclocked results, I had to use the following settings:

I tried higher voltages, but I was unable to get the memory speed higher with satisfactory stability. Perhaps upcoming X38 chipset based boards will let me go higher? 


OCZ has always been one of the forerunners for producing the really high end modules out there.  It's no surprise then that they would be one of the early companies to offer 1800MHz DDR3, and I was very pleased that the OCZ DDR3-1800 modules ran at 1800MHz without any tweaking being required - it worked the first time I tried it at its specified speed.  So far Corsair, Super Talent, and OCZ have modules at these really high speeds, and of the three we've tested two - the OCZ was definitely the more reliable of the two.

There is no guarantee that it will reach that speed on other motherboards, but the fact that it painlessly reached it on our Asus P5K3 Deluxe WiFi test bench is a very good sign; as (unfortunately) a lot of high-spec modules are only validated on a specific motherboard.  The last super highend DDR3 memory module we tested was the Super Talent DDR3-1866, which for example gave us some headaches on a couple of boards, but did run at spec on the ASUS Blitz.

If you are looking for a high-performance DDR3 module, you can't go wrong with the OCZ DDR3 PC3-14400.
