Sources close to Intel have revealed that RAM support for Sandy Bridge-E will be up to an official DDR3-2133, with motherboard manufacturers offering up to around DDR3-3000. The official support on Sandy Bridge only goes as high as DDR3-1333, so this is quite a large jump.
Base clock overclocking returns once more, but with a twist. Much like overclocking an old Pentium 2 using DIP switches for 66MHz, 84MHz or 100MHz there will be various “base” speeds for the BCLK which can then be fine-tuned by up to 5% in either direction. This means that selecting a BCLK of 100MHz will allow a fine-tuning range of 95MHz to 105MHz. Unfortunately, we don’t know the base speeds at this moment in time but expect an update as soon as we know. Jonathan Horne
