  • 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 1866 MT/s instead of 1866 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 933MHz per second, but the effective rate is 1866 megatransfers per second (MT/s) because there are 933 million rising edges per second and 933 million falling edges per second of a clock signal running at 933 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 Micron 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 Micron 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:
