G.SKILL Ripjaws X Series 8GB (2 x 4GB) Model F3-17000CL9D-8GBXM with Asus M5A97 R2.0

I know it's not on the QVL list but was wondering if anyone has this setup and can report how well it works/if any sacrifices have to be made that would make it less worthwhile than an 1866 with lower CAS perhaps. Just figured good price 2133 with CAS 9 is something to go for but I don't want to get useless ram or be better off with something else. Thanks!

  1. What CPU? If an FX 8320 or better can prob run at 2133, if a lower end FX CPU then possibly 2133 else prob 1866
  2. FX 6300
  3. May have trouble running 2133, but if good price can prob run 1866 with no prob
  4. The FX-6300 will have to have it's CPU-NB overclocked to 2200mhz to support the 2133MT/s memory speed. Bump up the CPU-NB to ~1.25-1.30V and it should run both the RAM and CPU-NB at these speeds without too much fuss.

    For even better results, buy a kit with dual rank DIMMs instead.

    A crucial ballistix sport kit (1600-9-9-9) will out-perform the ripjaw X (2133-9-11-11) in lots of workloads because the ballistix dimms are configured dual rank, which allows the memory controller to leverage rank interleave, which reduces effective access latency. The sport kit can be bumped up to run at ~1866-9-10-10 or 2133-10-12-12 with about 1.65V thrown at it, further improving performance.

    The dirty secret of 4GB DDR3 dimms is that most of them are now configured single rank to cut costs. They are marketing kits with high speeds and tight timings as performance memory, when really, it isn't.

    Black RipJaws X and Trident X DDR3-2133 9-11-11 specs have been dual rank for some time, they will surely outperform any DDR3-1600 CL9.

    F3-17000CL9D-8GBXM, the kit OP mentioned is also dual rank, double sided, surely better than any DDR3-1600 CL9 on the market.

    Hello G.Skill Support,

    Until you update your product pages with rank configuration information for each kit, we have to assume the worst case scenario. As a disappointed owner of the F3-2133C9D-8GXL kit, I don't see any way of distinguishing which of your kits are configured single and which are configured dual rank. Obviously, 8GB dimms are all configured dual rank, and TridentX kits have always been, but there does not seem to be rhyme or reason among Ripjaw/X/Z/Sniper/Ares kits.

    In the case of Crucial, they've made a very clear distinction. All 4GB dimms sold as "ballistix" are configured dual rank. Simple.

    As far as we the consumer is concerned, G.Skill has chosen to mix single and dual rank component configurations within the same "series" of memory, which means we really have no way to know what we are getting until we get it and decode the component configuration. I have contacted G.Skill by email asking if they would be willing to include rank configuration information on the product pages, or help "advanced" consumers decipher which kits are dual ranked (perhaps there's a way to do this by deciphering product numbers?). Unfortunately, I received no reply.

    As it would turn out, I have contacted several major memory brands with similar inquiry, the only one to respond with useful information has been Crucial.
