Actually, socket 2011 has gone through three generations: the first two generations using CPU Sandy-E (such as Intel Core i7 3820, i7 3930K and 3960X) and Ivy-E (such as Intel Core i7 4920K, 4930K, 4960X), it was running on Intel X79 chipset motherboards with DDR3 RAM. The 3rd generation is Haswell-E, it’s running on the Intel X99 motherboard with new DDR4 RAM.
If you look at the Socket 2011 X79, it has existed for nearly 4 years, and the X99 chipset will also have the same time cycle before a new platform released to replace it. The new Intel X99 chipset supports up to 48 lane PCI-e 3.0, DDR4 RAM, 10 ports of SATA III, USB 3.0, SATA-E, M2 Ultra supports up to 32 Gb/s.

This review is using MSI X99S SLI Plus mainboard with Haswell-E Intel Core i7-5960K and Ripjaws 4 DDR4. Here’s the first look at MSI X99S SLI Plus mainboard, you can look more with the gallery below.
MSI X99S SLI Plus Mainboard
Intel Haswell-E Core i7 5960X Extreme Edition
The Intel Core i7 5960X EE commercial version sold without fan, you need to select your own fan. More power than Haswell / Haswell Refresh, the Haswell-E i7 5960X also got temperature better.
DDR4 G.SKILL RIPJAWS 4 – RED 16GB (4x4GB) bus 2133, cas 15
DDR4 is a new generation of RAM and runs on X99 chipset platform, supports for dual channel, triple channel and quad channel. Advantages of DDR4 RAM are high bus speed with low voltage (1.2volts), more efficient, run cooler; and the read, write and copy speed of DDR4 is outstanding than DDR3.
Intel Core i7-5960X Xtreme Edition Benchmarks
3.0 GHz is a default clock of the Intel Core i7-5960X with 8-core and can reach to 3.5 Ghz with Turbo Boost (depend on mainboard, not all core can reach this clock). Therefore, the specific results of it can’t be determined, there are some mainboards only get 3.0GHz, some get 3.1, 3.2, 3.3, 3.4 or even to 3.5GHz.
With the default 3.0 GHz clock of the Intel Core i7-5960X:
At 3.3 GHz clock with maximum 8-core:
At 3.5 GHz clock with Turbo Boost:
At 3.7 GHz clock, with OC Genie: an automatic overclocked feature of MSI X99S SLI Plus mainboard
DDR4 G.Skill RIPJAWS 4 Bus 2133 Cas 15 Benchmarks
Usually people think the performance of RAM mainly due to the ram parameter, it is true, but not enough, the ram controller (IMC) is located in the CPU, so it also depends on CPU, each CPU will give different scores to test the RAM and also affected by CPU clock.
In the ram test scores, I choose the CPU clock at 3.3GHz, an average clock between 3.0 GHz and 3.5 GHz, and try different ways of plugging RAM with 8 DIMM of main, and bus ram at 2133, cas 15.
First, just test single channel with 1 x 4GB, plugging it into the first slot on the left, nearby the I/O connectors.
Next, dual channel with 2 x 4GB, gain double Aida64 scores.
Triple channel with 3 x 4GB of DDR4 G.SKILL RIPJAWS 4 bus 2133, cas 15
Test quad channel 4 x 4GB of DDR4 Gskill Ripjaw 4, it gains very high Aida64 score but Maxxmem not increase much. Where is the problem ? I suspected that the old software from Aida 64 is affected to the score, because it has not announced support for new platforms.
Another case which is also running quad channel that plugging all 4 x 4GB in the left (or right), but it gains low score, you should not to do.
32GB (8 x 4GB) quad channel will gain more speed than 16GB (4x4GB).
Also, clock of the CPU is affected to RAM speed. As below, at the 3.7 GHz clock, test points by Maxxmem had some differences. I haven’t any other Haswell-E i7 CPU to test but suspect that the i7 5930K or 5820K will give lower scores.
