Installation & Overclocking
We installed the Viper Xtreme Division 4 kit in our Intel X79 test system, which is comprised of the following items.
Processor: Intel Core i7-3820 CPU
Motherboard: Gigabyte X79-UD3 Motherboard
Video Card: Sapphire Radeon HD6950 Video Card
Power: Thermaltake 1200W Power Supply
Storage: 750GB SATA Drive
Cooling: Zalman CNPS12X
Case: Cooler Master Cosmos II Case
Memory is extremely easy to install, just simply put it in and push it down to lock it into place. As I said the heatspreaders on these modules are a bit larger than just a plain module so you are going to want to make sure they will fit in your system if you are using an aftermarket CPU cooler.
Next go ahead and turn on your system. Go into the BIOS and enable the XMP profile. This will set your memory to DDR3-1866 with timings of 9-11-9-27 and the voltage to 1.65v. As we load into Windows and open up CPU-Z we can confirm these settings.
Overclocking memory on the X79 platform is pretty easy is because for the most part you are overclocking the memory independently of the processor. The first thing I always try to do is bump the memory up to the next step, which in this kit’s case is 2133MHz. To my surprise the system booted just fine and I ran a stability test and things were fine. So this kit will run at DDR3-2133 with timings of 9-11-9-27 with no voltage adjustment at all!
Now I tried to go higher, even by adjusting the BCLK frequency on the motherboard and although I was able to get the system to boot with at higher speeds none of them were completely stable so I decided to stay with the DDR3-2133 overclock.
