ASRock Fatal1ty X99M Killer mATX Motherboard Review


We will outline the performance increases that can be obtained from using the ASRock Fatal1ty X99M Killer motherboard to overclock our system. Our overclocked processor frequency was 4.5GHz and memory speed was 2400MHz.

As a performance comparison, we have included the overclocked results from four other X99 motherboards. The maximum overclocked configuration achieved with each board was a 4.5GHz processor frequency and 2400MHz memory speed.

OC 3DMark

OC cinebench

OC Bioshock

With the CPU overclocked to 4.5GHz, ASRock's X99M Killer continues to show positive performance numbers thanks to its 300MHz CPU cache frequency advantage over the competition.

  1. Did you ever get the RAM issue with reboots with high speeds sorted? I am having the same issue, although when my PC reboots it doesn’t fail to start up, but with tight timings on my current 16GB set (CL12@2666) or high speed (CL14@3200Mhz) I can’t get the PC to stay turned off, but other than that the RAM runs fine for day to day use if I keep the computer turned on. I am on the latest 3.30 BIOS revision as well.

    Thanks

  2. You’d probably be better off with the newer USB 3.1 revision of the board, it has the OC Socket with extra pins and is way better for RAM, especially overclocking.

  3. Thanks for the reply! I may look into that, but not really in a position to replace the motherboard. It’s been a little over a year since buying. Wonder if they could offer some form of trade-in for this issue since it does look like a BIOS bug/glitch? Or I would probably assume this would fall under a clause of, “Not officially supported RAM, so nothing we can do”. Anyone have any experience working with ASRock on these kind of issues?

  4. I bought exactly the same setup 2 years ago. The the Asrock F-Streaming overclocking software could not get a stable result. Not even at 4.0ghz. Read the article and emulated your 4.6ghz settings at 1.36v. Stable as a rock. Ended up at 1.33v. Below that it becomes unstable. Aircooled (noctua NH-D14) never get’s above 60c under load and idles around 25-30c. Was thinking about getting a 7700k but there’s no need for that now. Thanks.
