G.SKILL Ripjaws 1866MHz 8GB DDR3L SO-DIMM Memory Kit Review

Overclocking and Final Thoughts


Overclocking the G.SKILL F3-1866C11D-8GRSL notebook memory kit wasn’t that exciting. We went into the BIOS and raised the multiplier to see if 2133MHz was possible with CL11 or CL12 memory timings, but wasn’t able to get the system to successfully post. We then tried to see if we could tighten the timings and had some better luck. If you recall in our introduction we told you that for $2 more, that you could get this kit of memory with CL10 timings programmed into the SPD  table and not CL11. We’ll we were able to run this kit at 1866MHz 10-10-10-28 with 1T command rates versus the standard timings of 11-11-11-32 1T. Not a huge difference, but it just goes to show that you can save some money and lower the timings on this kit if your platform allows it.


We ran AIDA64 v4.00 again and found that the read memory bandwidth and overall module latencies improved just a bit with the tighter timings. The latency of the memory kit is down to 87.3 ns, which is pretty good for notebook modules!

Final Thoughts and Conclusions:

Our testing showed that enthusiasts will want to run 1866MHz DDR3L memory in their system if possible. We found 3 to 15 percent performance gains when using a 1866MHz CL11 high-end memory kit versus a ‘standard’ 1600MHz CL11 memory kit on the Intel NUC Kit D54250WYK. The G.SKILL RIPJAWS Series 8GB 1866MHZ CL11 memory kit that is sold under part number F3-1866C11D-8GRSL ran great in the Intel NUC and made the Intel Core i5-4250U powered system feel faster! Changing out the memory or buying memory like this in the first place is one of the simplest ways to get a little more out of your system. We also love the fact that this kit comes with CL11 timings, but can be manually set to tighter CL10 timings on platforms that allow for advanced manual memory timing changes.



The G.SKILL RIPJAWS Series 8GB 1866MHz CL11 memory kit that we showed you here today runs $82.99 shipped and is lifetime warrantied. This kit is $17 less than the Corsair Vengeance 8GB 1866MHz memory kit and $22 less than the Crucial Ballistix Sport 8GB memory kit, which are the only two comparable 8BG 1866MHz DDR3L memory kits on the market today. The G.SKILL RIPJAWS F3-1866C11D-8GRSL is a solid kit of memory and it is clearly the price versus performance leader right now. It should be noted that this is the lowest cost 8GB 1866Mhz DDR3L memory kit out there, but you don’t miss out on anything!

We can easily recommend the G.SKILL RIPJAWS F3-1866C11D-8GRSL memory kit to those building an Intel NUC, Gigabyte BRIX or anyone looking to speed up their notebook/Ultrabook!

Legit Bottom Line: The G.SKILL RIPJAWS Series 8GB 1866MHz CL11 memory kit has an attractive price, can be run at tighter than advertised timings and helped improve system performance!

    I have a Brix i3 4010u. Will this definitely take 1866mhz RAM? I looked at the SoC and Brix website and it states 1333/1600 only. So I ordered some 1600 Crucial RAM. I had the Ripjaws in my basket but cancelled at the last minute because I wasn’t sure.

    Could you tell me if i can use this 2 RAM in my Asus N56J Laptop with 1600MHz bus speed?

    G.Skill Ripjaws 16G(2×8) 1866Mhz DDR3L 1.35v CL10
    G.Skill Ripjaws 16G(2×8) 1866Mhz DDR3L 1.35v CL11

    And does this mean i can get 1866Mhz bus speed in my 1600Mhz laptop?
    Another question which one is better? CL10 or CL11?

    Thank you

    Is it worth to buying DDR3L? Does it increases the battery life of a compatible laptop significantly?

  • Olly

    Would the best choice now be the new G.Skill Ripjaws 2133mhz memory, also reviewed here on legitreviews? It uses new 4gb chips, so half the number of chips and using less power, with less heat? And if I just want the easiest, most stable setup then in Bios would I set a lower speed such as 1866mhz? I’ve just bought a new Intel i5 NUC and now need RAM so I’d really appreciate a comment thanks.

    What is the best choice, 1600mhz CL9 or 1866mhz CL10 or 1866mhz CL11 G.Skill Ripjaws if you want 110% stability on D54250WYKH, is Kingston KVR16LS11/4 a more safe choice ? 🙂

    • Nathan Kirsch

      I’ve been running this 1866 MHz memory kit in the NUC since December with no stability issues at all with tighter CL10 memory timings. Brand preference is really up to you as the costs and all that do differ as do the warranty processes. No company tells you failure rates, but both brands have loyal followings.

        Thanx for the quick reply, it seems like i only can buy F3-1866C10D-8GRSL as you wrote about on page 1, so in your view this will be a good buy, and i dont have to tweak the CL, but i am surely not married to Kingston, it was the shop that recommended Kingston 1600mhz, the Price differens are so Little that i would rather have the better performance in the G.Skill ram 🙂
