Cool [review] OCZ PC4000 GoldVX + DFI NF4 @ Anandtech.com

In the past year, we have seen lots of memory rated at DDR500, so you may wonder why we are reviewing a new DDR500 memory today when there are now a few rare modules rated as high as DDR600. The answer is pretty simple, since OCZ PC4000 VX Gold is the only memory that we have ever seen rated at DDR500 2-2-2. While it is rated at DDR500 at these extraordinary 2-2-2 timings, it also carries a very high rated voltage of 3.3V - far beyond what most motherboards can supply.

A quick check of orbs at FutureMark will show that this new VX is the fast darling of the extreme overclocking market. For those who wondered why DFI included voltages to 4.0V in their new nForce4 Ultra and SLI motherboards, the answer is OCZ VX memory. With VX needing voltages as high as 3.7V to really reach top performance at certain speeds, the DFI LANParty nF4 SLI-DR and DFI LANParty UT nF4 Ultra-D are the first production motherboards to support the kind of extreme voltages needed by VX without modification.

With this promise of extraordinary DDR500 2-2-2 performance, we were very interested to see if this performance promise was real. Have we finally reached DDR500 with the fastest timings available? The answers in our benchmarks are very interesting....

OCZ EL PC4000 VX Gold
OCZ has developed quite a reputation in the past year with the introduction of many leading-edge memory products. As you will see in a look at our ongoing memory benchmarks, the results have been that OCZ owns many of the top performance spots in our memory tests. Even with that kind of reputation, OCZ VX must be counted a unique product. The EL label is used by OCZ for Extreme Latency, but VX is a new label used to refer to Voltage eXtreme memory. VX means that the memory is designed for and can handle very high memory voltages for expanded performance.

The first OCZ VX memory was rated at a very conservative PC3200 2-3-3-8 at a standard 2.6V. While it met these specifications, the specs hardly described a memory that was widely recognized as capable of DDR500 and higher at 2-2-2 timings using voltages of 3.0V and higher. As yields and binning improved, OCZ decided in late February to introduce an updated VX memory - now rated at DDR500 2-2-2 at 3.3V.

The new DDR500 2-2-2 uses the same chips as the earlier VX, but it is binned for higher speed and verified at the new DDR500 specifications. OCZ tells us that everything about the new VX memory is basically the same as earlier PC3200VX, but with even better chips becoming available for VX, it was time for the higher speed rating. OCZ will also be introducing a VX value memory in the future for those enthusiasts that want 2-2-2 timings, but do not demand DDR500+ timings for 2-2-2. Gold VX modules are optimized for use on Athlon 64 based motherboards. In addition, OCZ EL PC-4000 Gold VX is rated to handle up to 3.5V without invalidating the OCZ lifetime warranty.
