OCZ Technology on Wednesday announced its memory modules capable of operating at unprecedented high speeds, but only on specially created mainboards for overclockers by DFI.

In the past makers of memory modules for enthusiasts and overclockers designed their products by using advanced memory chips with low access time and installing heat-spreaders. Not so long ago the manufacturers of modules began to recommend increasing memory voltages beyond normal levels and then OCZ even revealed a special device that can pump up the memory voltages to extreme levels. Today the industry goes one step further towards proprietary solutions for overclockers as OCZ Technology brings out memory modules designed and certified to run at 625MHz only on AMD Athlon 64 processors and DFI nF4-series of mainboards.

“As a recognized pioneer in offering the highest possible memory frequencies, OCZ developed the PC-5000 Platinum DFI nF4 Special series with performance enthusiasts in mind,” OCZ Technology said in its statement.

The evolution of DDR memory type was officially suspended on the clock-speed of 400MHz with further speed increases fully relied on DDR2 SDRAM. Nevertheless, the industry of manufacturers who server the growing community of those who push their personal computers to the limits have managed to increase the speed-bin of DDR memory gradually to 466MHz, 500MHz, 550MHz, 600MHz. Today OCZ can guarantee that DDR will run stably at whispering 625MHz, provided that its customers have an overclocked AMD Athlon 64 processor on a mainboard based on NVIDIA nForce4 core-logic made by DFI.

“Motherboards and memory modules are always considered the two most critical factors for achieving excellent performance, but truly perfect matches can be challenging to find, and a tailor-made memory module for a specific motherboard catering to enthusiasts is unprecedented,” stated Jacky Huang, General Manager, DFI Inc.

OCZ PC-5000 EL DDR Platinum DFI nF4 Special of memory modules is certified to run at 625MHz with CL3 4-4-10 latency settings. The company claims that memory voltage should not be extreme to achieve the speeds – the default rating is 2.85V – still the modules can handle up to 3.0V voltage. The products are available as 512MB DIMMs or 1GB dual-channel kits. The pricing and exact availability time is unclear.

The latest achievement of OCZ Technology is DDR SDRAM modules capable of 600MHz speed with CL2.5 4-4-10 latencies at 2.85V able to operate at any advanced mainboard.
