Surprise from PATRIOT memory manufacturer UPDATED* 26.02.2017.

I want to share my extraordinary experience with one of the greatest memory brands - PATRIOTmemory.com.
As described on my BLOG from few years ago (http://alenajanovic.blogspot.ba/2014/03/experiance-with-intel-masters-extreme_16.html) I was honored to own 32GB of PATRIOTs DDR3 INTEL EXTREME MASTERS Limited Edition memory. The work and gaming went smooth for years with these modules, and their look was a pleasure for eyes in my machine so PATRIOT bought my attention.

Suddenly, after years of hard usage, one module became unstable. Regarding I was very pleased with PATRIOT + having “life warranty” I decided to try and ask for replacement. Company answered very fast. Unfortunately, INTEL EXTREME MASTERS as a limited edition type was out of stock BUT, if I want I can have replacement kit called BLACK MAMBA with same specifications and I accepted it with stunning conclusion that company wants to send me an extra 32GB of DDR so I can double amount of RAM on my 8 DIMMs motherboard from 32 to 64GBs... FREE OF CHARGE. I was confused and surprised at same time... Considering a lots of work with CG, animation, compositing and the fact that my motherboard supports up to 128GB of RAM with its 8 DIMMs, who could refuse such generous offer?!

So here it is! PATRIOT sent me a gift of brand new 32 + 32GBs of BLACK MAMBA VIPERs.


For those who wants to learn a bit more about this memory, keep on reading.

As on PATRIOTs official link for this memory: https://patriotmemory.com/product/viper-3-32gb-4-x-8gb-ddr3-2133mhz-pc3-17000-quad-channel-memory-kit/ this quad kit modules operate on 1600 and 2133mhz with XMP on. I have nothing special to say about it beside what I already said about its successor INTEL EXTREME MASTERS. They are decently stable in line of 8 modules but slightly slower than INTEL EXTREME MASTERS - really not a big deal. The reason might be anything considering the testing was made on pretty demanding configuration:

CPU 3930K

2 x Ge Force 780 Ti
8 x 4GB 2133 PATRIOT VIPER Black Mamba (Quad channel)

The important fact regarding factory XMP settings is that system does become unstable with BSODs but with manual settings aiming full 2133mhz potential and CPU boosts, system will be just fine. I am sure that stability depends on compatibility of hardware components and their BIOS settings.

XMP options that should be fixed to have stable system are:

DRAM Frequency to 2133
DRAM Voltage (CHA, CHB) raise from 1.65V to 1.65V
DRAM CAS# Latency change to 12 - 12 - 12 -12 -27 -2

and benchmark results, for DEFAULT vs. XMP settings are:

For absolute balance of stability and performance there is an optimum settings of 1866mhz and latency CL 10-11-10-30-2, DIMM voltage 1.6V

ASUS P9X79 PRO has its BIOS OC adjustment option and mathematically it does a great job regarding stability and overclocking up to 20%. Somehow there is a sort of choke going around during basic work with windows and even default settings works better than this ASUS calculation.

Anyway, who is interested, here is the result for this option (ASUS P9X79 PRO BIOS Auto OC)
