CellShock PC2-6400 (DDR2-800) 2GB Kit
Published: 22nd May 2007 | Source: CellShock | Price: |Introduction
Here at Overclock3D we often get asked to take a look at products from new and upcoming manufacturers who are desperate to get their name out into the open. The normal candidates include cooling applications, cases and power supplies. So when we was approached by a relatively unheard of company called CellShock and asked to review one of their DDR2 kits, I literally jumped at the chance. I have to be honest at this point and say that the CellShock name wasn't new to me prior to this review, but for those of us who haven't been acquainted with this company in the past, here is a snippet of information from their website:
|Since 1979 MSC Vertriebs GmbH has made a name for itself as one of the leading high-tech distributors of electronic components in Europe.|
Producing user memories in all variations and specifications for industry has always been one of MSC's core competencies. And now, with the new CellShock series, we are applying the knowledge gained to DRAM memory systems for PC fans. We use special techniques for chip selection and printed circuit boards with enhanced layouts including exhaustive quality testing. We also have contracts with a variety of reputable manufacturers of memory chips and electronic components that enable us to access a wide assortment of applications for optimizing our products.
With well established names like OCZ, Crucial, Kingston, Corsair and Muskin already providing some of the fastest DDR2 kits available, it's hard to believe that any new company would even consider trying to break into this already fiercely competitive market. However, CellShock have their sights firmly set on a specific type of end-user...the overclocker:
|...the test programs we use were developed by overclockers for overclockers. We give that extra performance and compatibility - not because of some advertising slogans, but because we have a genuine passion for high-end PC components. We want to make a believer out of our customers not only with our products, but also fast service and expert technical support.|
More information about the company and their products can be found here.
Also found on the CellShock site is information on their manufacturing process, and more interestingly, the specs of the DDR2-800 kit we are going to be looking at today.
|We select our memory chips according to our own internally developed techniques to allow later specification and assignment. We build 8-layer boards for DDR2 modules (6-layer boards for DDR1) according to our own enhanced layout. They are equipped with the galvanic hard-gold contacts that are used in industry. Our printed circuit boards are checked for impedance making reflections or interference in signals virtually impossible. Our modules are also equipped with heat-dissipating heat spreaders available in 2 variations depending upon model specifications.|
• Speed: DDR2 800 (PC6400)
• Timings: 4-4-4-12
• VDimm: 2,1V - 2,2V
• Chip: Micron D9GMH 64Mx8
• PCB: 8-layer, 240pin
• Guarantee: 5 years
The CellShock DDR2-800 modules are based on an 8-layer PCB for maximum stability and make use of the highly regarded D9GMH IC's manufactured by Micron. Each kit is provided with a 5 year guarantee, which is a bit strange as most kits from other manufacturers come with a lifetime warranty. However, saying this I certainly don't think I've ever kept a memory kit for anything longer than a couple of years with the way technology changes, so this shouldn't pose much of an issue for the majority of enthusiasts.
With timings of 4-4-4-12 and VDimm warranted up to 2.2v, there is certainly room for overclocking, however let's take a closer look at the modules first over the next page.
