Latency and Efficiency

DDR3 Memory Round Up Latencies

Memory timings affect computational projects. So if you're doing a lot of video editing, lower latencies will help reduce work load time. That said, the above table compares each memory kit's efficiency and timings. The lower the timings, the higher the efficiency. You'll see these come in to play during some of the benchmarks.

SANDRA - Memory Bandwidth

Frequencies and timings dictate the amount of bandwidth readily available from each memory kit. The more bandwidth, the greater the amount of data can be moved.

While these numbers seem uneventful, this is actually in Gigabytes per second. To put it in perspective, current AMD processors are about 10GB/s slower. And, even older Intel systems don't see this much bandwidth. Interestingly, the Platinum 2666MHz memory appears to be as fast as the HyperX 2800MHz. This is probably a combination of IMC tuning and memory module selection.

When all the transcoding is finished, we can see that memory frequencies don't impact performance as much as the memory timings. Lower timings (which are better) mean the CPU can request and access data from the RAM in a shorter time thus quicker project completion.

To shed some better light on the subject, in our Patriot Memory Viper III Black Mamba 2133MHz review, the CPU running at 4.4GHz does better transcoding work with lower timings and memory frequencies versus higher. If you're planning on doing a lot of content creation, memory kits with lower memory timings are your weapon of choice.

PCMark7 - PCMark, Productivity, and Computation

PCMark7 is a different story. There's so much data moving around this benchmark that faster frequencies and lower timings both impact the results. Below is the results from each illustrious memory kit.

Memory frequency gives the system something to really chew on in PCMark 7. As the CPU is overclocked, the sub tests of computation and productivity see scores increase as the memory frequencies increase, giving the system more data to play with. The Platinum is naturally the fastest and therefore scored the best in this test.

Cinebench R11.5

As mentioned before, memory timings mean all the difference when it comes to rendering. Cinebench is quite CPU intensive and does more with higher frequencies. Timings can also influence rendering times. Here, I tested just the stock rated memory settings with a stock and overclocked CPU.

Leading the pack is the Mushkin Redline 1600 because of its CAS 7 timings. While I'm unsure what CAS 7 ICs are underneath, we do know that Patriot's Venom (Viper III) Hynix ICs are extremely well tuned and stay close on the Redline's heels. Otherwise, the field is separated by just a couple frames on the average. Keep in mind that much larger renderings will complete in much shorter noticeable times on memory with lower timings.

Now let's give our final take on each kit and try to answer the burning question: Which kit is best for you!

    "That said, each one of the kits tested are my recommended choices for
    optimal performance at each frequency level and here’s why."

    So, why?

    Are you leaving this is a cliff hanger or did you miss a bit when you C&P'd?

  • Eric Garay

    Hi Dean, thanks for reading the review. My apologies as I didn't mean to leave the why and each kit's Final Thoughts so disconnected. While each manufacturer offers two or more DDR3 memory kits, these are each manufacturer's optimal performance memory product that are still currently offered. -- Mushkin (Redline) offers the only high quality low latency memory, Kingston is often the most used for system integrators simply for price and stability, Patriot Memory Viper 3 is the best mid-range overclocking performer, ADATA Gamer Series V2.0 typically the most affordable in the 2400MHz range which also happens to be the average maximum for current Ivy Bridge processors to support, and Corsair Dominator Platinum not only arguably the best looking enthusiast's memory, it's also the overclocker's choice.

    Again apologies, and definitely appreciate you bringing that up. If you don't mind me asking, what kind of memory are you currently using?

      Hello, Eric.

      A good follow up to the review, I enjoyed the read.

      As to your question, I currently use 12gb (6x2) of OCZ Platinum Low Voltage @ 1600mhz with 7-7-7-24 timings using 1.6v. When I ran 6gb, I had it dead stable at 1900mhz with 9-7-7-24 timings at 1.68v. This was with an i7 920 at 4.2ghz on an Asus Rampage Gene 3. I could overclock the ram but with the little time I currently spend in front of the PC for gaming, I see no need. Especially since the system is still quite fast, even with the 920 sitting at a lazy 3.8 nowadays 🙂

      • Eric Garay

        Oh, you got some of that elite OCZ Platinum DDR3! I swapped their Platinum and camouflaged memory heat sinks for a while just to show off. Kingston has some low voltage (Genesis green) that was very similar but no way I could get it stable at 7-7-7-24 or 8-8-8-24. In fact, OCZ was the only other memory manufacturer that offered really low latency DDR3 until last year when they shut that division down. As far as enthusiast level m-ATX go, that ASUS Rampage GENE III was easily Editor's Choice. I very much enjoyed the GENE IV as well. Hardware implementation is as good as it gets really. About the only thing you may need in the future is a video card upgrade, if you decide to play a serious game.

        Again, appreciate the comment and question good Sir!
