x264 HD Encoding


Simply put, the x264 HD Benchmark is a reproducible measure of how fast your machine can encode a short HD-quality video clip into a high quality x264 video file. It’s nice because everyone running it will use the same video clip and software. The video encoder (x264.exe) reports a fairly accurate internal benchmark (in frames per second) for each pass of the video encode and it also uses multi-core processors very efficiently. All these factors make this an ideal benchmark to compare different processors and systems to each other. We are using x264 HD v5.0.1 for this test. This application scales across many threads and is ideal for processors with Intel Hyper-Threading or a bunch of cores.



Benchmark Results: The x264 HD v5.0.1 benchmark showed that at 2133MHz with CL14 timings we were averaging 98.96 FPS on pass 1 and 27.49 FPS on pass 2. When we set the UEFI/BIOS to XMP Profile #1 we were seeing 106.81 FPS on pass 1 and 29.14 FPS on pass 2 at 2400MHz with CL16 timings. This is a 6.0% performance increase on the second pass with the memory running at 2400MHz versus 2133MHz. Once you get beyond 2133MHz it doesn’t appear that X264 needs any additional bandwidth. We were a little shocked that the Crucial kit running at 2666MHz with CL12 timings didn’t have any real performance increase over the testing at 2666Mhz with CL16 timings. If you do video work you’ll really want to consider a DDR4 memory kit with clock speeds above 2133MHz as it will save you significant time on your rendering jobs over the years and many people are buying Haswell-E platforms for CPU intensive tasks like that.

    AIDA64 Cache&Memory Benchmark!

    ns(Higher = Better) ??


    ns(LOWER = Better)?

    How long did you test this ram for? I’ve seen a couple of reviews state 12-12-12-30-1t but it’s no good, HCI memtest found an error after running for quite a few hours. 13-13-13-30-1t successful so far after 12 hours, not completely sure yet.

    I don’t think you guys tested this ram properly.

      i have same kit running 12-12-12-30 1t @2700 at 1.35v , never blue screen yet

    Dummies question: I have this RAM and a Asus X99-A motherboard, how to I overclock the RAM as described here? I do not find where to change the RAM timings in BIOS. Thanks in advance!

  • Wow that ant cool, why wouldn’t they not program an XMP #2 profile, seriously though someone looking at the spec would just get thrown off, if they were looking for such a feature that should exist.

    Still would purchase Patriot memory over any Corsair product followed by Crucial Micron. Nice review but wish you had AID64 thrown in there.

      We do have AIDA64 results in the review.

      depends on rum maybe but all have problems with set XMP 3000+ on x99;
      (msi x99a sli plus and mem 2xf4-3000c14d-32gtz); xmp set bclk 125 and it’s evil of stability not sure why no good bios to prevent it; maybe will appear in future maybe not;

      be careful with xmp and bclk changes on x99;

      was able to get on my mobo with 100 bclk 3200 (was avialable in bios to set manual 2666 or 3200) with timings 14-14-14-34

      later will check with HCI memtest but before will find best combination of freq and lower timings with aida; then HCI memtest, it look like best mem test and cpu full load (if run few instans correctly) and perfect system real stress test 🙂
