It looks like Computex will be very interesting for the memory speed addicts amongst the overclocking crowd. As a screenshot from the CPU-Z application leaked through - the source remains anonymous, we can see the magical barrier of DDR3-4000 has been broken! The fact that this screenshot has not made it public or, well, to a press release indicates this overclocking result was achieved on an upcoming platform. But which platform?

After all not only Intel is launching a new micro-architecture in the next month, AMD is as well. They are releasing the new Richland-based APU soon. We all know how strong Llano was for memory overclocking - Christian Ney still has the overall DDR3 record set at DDR3-3900MHz (reference) - and so far it is unclear whether the new AMD platform is capable of beating that. In any case, the DDR3-4K is true as it has been confirmed by multiple sources that will be the new target for memory overclockers.

The frequency was reached with a single stick of single sided Hynix MFR memory.
