You can verify the compatibility of this RAM module in a number of ways:

  • Use the RamCity Finder to see all guaranteed compatible RAM upgrades for your brand and model system or motherboard
  • Search online to see if this product is on the QVL (Qualified Vendor List) for your system or motherboard
  • Contact one of our Upgrade Evangelists for an expert opinion

Why is the speed of this RAM module shown as MT/s instead of Mhz?

When it comes to measuring DDR RAM speed, MT/s and MHz are used interchangeably, which is not actually correct.

DDR stands for double data rate which means data is transfers on both the rising and falling edges of the clock signal. Meaning that the transfer rate is roughly twice the speed of the I/O bus clock. This RAM module runs at 0MHz per second, but the effective rate is megatransfers per second (MT/s) because there are 0 million rising edges per second and 0 million falling edges per second of a clock signal running at 0 MHz.

Save 25% and more over buying a pre-configured server or workstation

Memory and storage account for over half of a typical server’s bill of materials (BOM) cost. Your CTO wants to keep a lid on spending but you need hardware that delivers the performance that your users need. By purchasing servers or workstations with minimal preinstalled components and then installing Kingston server memory, you can save 25% or more on your RAM costs – and maintain your OEM server warranties.

But don't I need to buy RAM and Storage components from my OEM to maintain the warranty?

Similar to how you can upgrade a system’s preinstalled processor or graphics card and choose whichever brand you want, you can also do the same with memory and storage. Laws in Australia, U.S. and all over the world protect comsumers and businesses so that you can swap out manufacturer pre-installed components for more cost-effective third-party components and still retain your product’s warranty. In practical terms, this means you can upgrade to Kingston brand memory without voiding your system’s original warranty. Don’t just take our word for it though, here’s what the manufacturer warranties say:
