OCZ PC12800 "Platinum"
OCZ has been a returning customer to our site for the last few years, and they couldn't be absent this time. For those that meet OCZ for the first time, an introduction to the company :
is one of the premier manufacturers of memory modules, and one of the biggest players on the international market. OCZ technology was founded in 2000 and has established quite a name for producing high end ram products, especially among the enthusiast community. Since early 2004, OCZ also produces high-end power supplies, and in 2007, OCZ also has put a new focus on cooling products, by introducing some eye-catching cpu-coolers. Recently OCZ acquired PC Power & Cooling, a high end PSU manufacturer, and Hypersonic, a (very) high-end system builder. Until now, memory remains the most important branch in OCZ's product catalogue, and as such we're lucky to test some of their ram today.
Let's see how the package looks like :
Like most manufacturers, OCZ has changed their package from a simple blister to something with a little more "bling", if you can call a cardboard box that. This box was actually designed to hold two blisters, and up to 4 modules. We reviewed
a quad module OCZ DDR2 kit not that long ago, which indeed introduced this box, albeit in different colors.
As mentioned, at the inside we find 2 memory blisters, a first one holding 2 modules, the second blister only 1. The blister with two modules also includes a simple, full color manual, something that OCZ keeps doing for the novices among us.

This is one of the modules that reside inside:
As the title already mentions, this kit is part of OCZ's platinum lineup, a lineup directed at the PC enthusiasts. As such, the modules are equipped with OCZ's standard "honeycomb" grill heatspreader, in a shiny silver-chrome finish. The platinum kit is standard height, on a green PCB, nothing fancy here. These modules are not directed at the case-mod enthusiast, or the Lanparty visitor, but are purely performance oriented. Therefore : no need for more bling, OCZ has other lineups to compete in those fields.

These are the specifications
that come with it :1600MHz DDR3 (PC12800)
Latencies : 7-7-7-24-2T (CAS-TRCD-TRP-TRAS-CR)
Operating voltage : 1.65 Volts
Parity : Unbuffered
Memory size : 3x 2048Mb
With these specifications, I doubted that the modules would fit in a midrange memory roundup. However, as prices are coming down rapidly lately, price differences between this and other kits have become very low, so I decided to include this kit here. I have a feeling that this kit will be EOL'ed quite soon though, as with the arrival of the new Elpida "B" variants, performance will no doubt go up. OCZ has already started offering cas 7 1866Mhz and cas 6 1600Mhz kits on their website, these are the true high end of DDR3 nowadays.
After the rather disappointing Mushkin run, I was very pleased that these modules overclocked rather easily to very pleasing levels. In this regard, the cas 7 headroom might be called rather limited, because at 810Mhz (but 1T instead of 2T) it provided only marginal additional speeds. At cas 8 however, things changed: the modules hit a solid 900Mhz fully stable, a little better even than the G.Skill competition. At cas 9, the modules continued to scale, barely missing the 1000Mhz mark and stopping at 972Mhz prime stable, 1T. 1Ghz memory speed was possible, when relaxing the command rate to 2T, or when you're happy with non-prime stable performance, which is fine for most tasks.
Finally, the OCZ modules were also fine with the low latency setting of cas 6 at 1333Mhz, a setting we'll be using later on for our performance tests.
