Yes you heard it right, it will be possible to overclock memory on Intel’s upcoming Ivy Bridge processor. You can overclock the memory over 3 GHz oh yes and that too done on 4 DIMMs is just totally crazy, Intel has surely made some improvements in their memory controller compared to Sandy Bridge.
A member of overclock.net/HWbot ‘Sin0822’ posted screenshots of him overclocking his memory past 3 GHz. His setup was an Intel Core i7-3770K coupled with Gigabyte Z77-UD5H and the memory he was using were 4 unnamed G.SKILL modules. UEFI has a 29.33 divider for memory which is something you can’t find in Sandy Bridge hence the reason for high memory overclock.
