Mixing Vengeance Black and Blue memory kits

By Jake Crimmins, on March 30, 2011

Our new Vengeance™ line of DDR3 memory is extremely popular. Due to strong demand from end users, we are now offering Vengeance modules in cerulean blue in addition to the original black. These color offerings provide Vengeance users with more options to enhance the aesthetics of their system.

If you want to mix a black and blue kit of our Vengeance memory, you are in luck — the Vengeance 1600C9 kits are specifically designed to work in four-up and six-up configurations! So, multiple kits can be purchased and installed in a single system without a hitch.

In order to get your system up and running, we recommend following a few guidelines to ensure optimum performance and stability.

The most important thing to do is make sure you order the correct kits. For example, if you already own or plan on purchasing the CMZ8GX3M2A1600C9 kit in black and you wish to add a blue kit, you would need to order the same exact part number except with a B (CMZ8GX3M2A1600C9B) at the end. The 1600MHz Cas 9 Vengeance kits are designed to run in a 4 up configuration, any other kits rated at lower latencies or higher frequencies may not run 4 up. See the chart below for the matching blue kits.

After purchasing the correct matching blue kit, there are a few ways to ensure best performance. Before installing the second memory kit, make sure you go into the BIOS and load the defaults. Doing so will wipe out any of the previous memory settings. This is to make sure the machine will post with both kits. Now you can move on to settings the proper memory timings, voltages and frequency.

The easiest way to accomplish this is to enable XMP in the BIOS. After loading theBIOS defaults, you can enable XMP to get your modules up to speed. See our blog here to learn how to enable XMP. After you have enabled XMP you would want to check with CPU-Z that the memory is running at the correct timings and frequency.

If you can't enable XMP or run into stability issues, manually settings the timings, voltages, and frequencies may be necessary. If you look on the side of your module the timings and voltages will be listed. The timings you would want to set are 9-9-9-24-2T (CAS-tRCD-tRP-tRAS-Command Rate) and the memory voltage is 1.5 volts. After you have those set you can adjust the memory frequency to 1600MHz. Depending on your platform, you may also need to increase the integrated memory controller (IMC) voltage as well.

After getting both kits running you will want to run Memtest just to make sure there are no issues. For a full guide on how to run Memtest see the link here. If you get any errors in Memtest you may need to raise theIMC voltage. If you continue to get errors in Memtest your memory controller may not be able to run both kits at 1600MHz and you may need to lower the memory frequency. In some rare cases, due to memory controller factors, BIOS revisions, motherboard revisions etc, there may be combinations of memory revisions that simply will not run together. Our suggestion in this case is to purchase a matched kit of memory that is guaranteed to run together at the rated specifications for your system.
