Overclockers UK were the first e-tailer to list the brand new DDR4 memory with the Crucial Ballistix range and now have expanded their portfolio to include Corsair's high performance memory now bringing it to the largest range of DDR4 in the UK. The memory is ready to order with already a few modules in stock ready to buy. Overclockers UK are well known to hit the market first with new technology. As X99 chipsets are just around the corner, we see the advancement in memory technology to DDR4. Overclockers UK were the first in the UK to list Crucials Ballistix DDR4 memory range with full specs and product details. Since then, Overclockers UK have expanded their DDR4 memory range to include Corsairs high-performance modules even including the well established Corsair Platinum range. Prepared like a coiled spring ready for X99, Overclockers UK will be ready with all the components customers need to upgrade to the latest technology, hosting a full range of motherboards, memory and even fully built X99 systems. With the addition of Corsairs DDR4 range, Overclockers UK now boasts the largest range to offer. Expert in memory and purchasing manager at Overclockers UK, Andrew Gibson well known by his alias "Gibbo" explains DDR4 memory technology on the forums for customers to understand, these are a few highlights : Voltage Voltage will start at 1.20v, I suspect we might see overclocked modules available which need 1.25-1.30v but time will tell. But as the technology matures we shall see 1.10v low voltage parts and even 1.05v ultra low voltage parts. So the power savings are considerable over DDR3, longer lifespan and less heat output. Densities As with DDR3 there shall be 4GB and 8GB modules. But the desktop consumer shall also see 16GB modules as well soon, something DDR3 only have available for server market. So on an X99 motherboard with 8 slots that means 128GB of memory if the motherboards BIOS can support that. Speed/Bandwidth This is the interesting one and potentially the most interesting for us keen overclockers, the speeds will come officially in 1600MHz, 1866MHz, 2133MHz, 2400MHz, 2666MHz, 3200MHz, 4000MHz and even maybe 4266MHz. These are official JEDEC speeds. Of course memory partners can release other speeds such as Corsair who are overclocking their parts upto 2800MHz, these are no doubt 2666MHz simply overclocked to this higher speed by Corsair themselves Connector 288-pin DIMM for desktop and 256-pin SODIMM for notebook. Form factors Unbuffered ECC or none ECC, registered and load reduced, so DDR4 shall be available for all desktop, server and mobile type applications. For more information, visit this page.
