Intel's 64-bit memory controllers rock hard and a lot certainly happened. Over the space of a couple of years we went from dual-channel towards triple-channel on X58 (Gulftown), then back to dual-channel with the Sandy/Ivy Bridge/Haswell architecture and with Haswell-E we get quad-channel memory support, this round with DDR4 memory.Īdmittedly, the Intel memory controller, whatever platform you choose, is super fast. Back in 2008 we already reported that the initial Nehalem architecture was quad-channel ready, they just had never implemented it up-to X79. One of the more hip features of the X99 platform is the ability to use quad-channel memory. With XMP memory you simply enable XMP in the System BIOS, and your memory will be pre-configured on the highest supported clock frequency, timings and voltage to ensure best performance versus maximum stability.
Most kits, if not all, will be Intel XMP 2.0 (Extreme Memory Profile) enabled and are guaranteed to work with motherboard partners like ASUS, ASRock, Gigabyte and MSI. The DIMM connector now has 288 pins (as opposed to 284 from earlier). Have no fear, as many memory partners will release DDR4 memory at even higher clock frequencies and, over time, lower latencies. The modules will be low voltage (1.2 V) DDR4 RAM. Even the OC modules at 3.2 GHz these days can run at only 1.30 Volts. You notice that default DDR4 system memory only needs 1.2 Volts, whereas DDR3 starts at 1.5 Volts. DDR4 right now offers better timings starting in the CL 14/15 range and has become much cheaper.
Intel will support JEDEC timed DDR4 DIMMs in steps of 1,333 MHz, 1,600 MHz, 1,866 MHz, 2,133 MHz and now 2,400 MHz. Starting with Haswell-E and now following with Broadwell-E, with the X99 chipset Intel made a move towards DDR4 memory.
