With a CAS latency of 14, the Team Xtreem kit leads the way in low-latency RAM favoured by gaming PCs, especially AMD Ryzen rigs. As such, it takes the top spot as our pick for the best RAM for. Column Address Strobe (CAS) latency, or CL, is the delay time between the READ command and the moment data is available. In asynchronous DRAM, the interval is specified in nanoseconds (absolute time). In synchronous DRAM, the interval is specified in clock cycles.Because the latency is dependent upon a number of clock ticks instead of absolute time, the actual time for an SDRAM module to.

CAS latency (CL) Clock cycles between sending a column address to the memory and the beginning of the data in response tRCD Clock cycles between row activate and reads/writes tRP Clock cycles between row precharge and activate. DDR4-xxxx denotes per-bit data transfer rate, and is normally used to describe DDR chips The formula for figuring out the true latency (as opposed to CAS latency) is: CAS latency / clock speed. That's a measure of time, usually expressed in nanoseconds, and you want to minimize it. The two kits you mentioned: 14 / 2400000000 = 6 ns. 16 / 3333000000 = 5 ns. On paper, the 3333 MHz RAM wins

Choosing Your RAM: What is CAS Latency and When Does it

DDR3 RAM usually has a CAS latency of 9 or 10, while DDR4 will have a CAS latency of at least 15. However, because of its faster clock speeds, the newer standard has better performance overall Cas gives you latency in clocks. The DDR4 frequencies are marketing numbers. You half them to get the real frequencies. DDR4 3200 = 1600 MHz = 0.625 ns per clock 0.625 * cas16 = 10.0 ns DDR4 3000 = 1500 MHz = 0.66(6) ns per clock 0.66(6) * cas15 = 10.0 ns So you see they have the exact same latency. The 3200 would give you 6.6(6)% more bandwidth

DDR4 RAM Speed vs Latency Explained: Is High Speed All

  1. CAS Latency. Who wins in CAS latency when it comes to 2400MHz vs 2666MHz DDR4 Ram? Both have different CAS latency in CL ratings. The 2400 Ram comes with 0.83 clock cycle time with CL17 CAS latency to makes sure good performance with less decelerate. On the other side, the 2666 Ram has 0.75 clock cycle time with CL19 CAS latency to run apps.
  2. Go back.. This is a RAM latency calculator. It takes the data rate (MHz) and cas latency (CL), then calculates the absolute latency for memory accesses in nanoseconds
  3. That means that if you are comparing two RAM modules with the same CAS latency, it is necessary to see which one has the higher frequency. A DDR4-2133MHz with C16 and a DDR4-3200 MHz with C16 will not have the same performance just because they have the same CAS latency. The DDR4-3200 will perform faster because it has a higher frequency
  4. 3200 (speed in MHz) / 16 (CAS latency) = 200. In this case, the performance of these two RAM chips is identical! Although one has a higher speed, its higher latency alters the performance to be equal to the level of a RAM chip with lower speed but higher frequency. This serves as a demonstration of how frequency and latency work hand-in-hand to.
  5. gs for Ryzen 3000, and personally, we would trust what the manufacturer recommends - if you do have a budget for your Ryzen 3000 build but want the optimum performance without going all-out on memory
  6. One crucial thing to point out with DDR4 is that it has an oddball CAS latency hole. You'll notice we jumped directly from C16 to C18; C17 isn't officially supported

Ram Speed Vs Cas Latency - Which Affects Gaming More For

Measured in MHz (Megahertz), is the effective speed the memory runs at. Generally, faster is better. But realistic gains for gaming performance fall off after 3600-3800 MHz for DDR4 in most scenarios. The higher the frequency, the more bandwidth you'll have, meaning the more data your CPU can process at once. CL (CAS Latency If the CAS Latency is the same on both then the 3600mhz is faster. The higher the frequency and the lower the CAS latency the better. There is a formula to determine the response time and the lower that is the better. I don't recall it of the top of my head. It's definitely worth it to do a little research UPDATE: 06/24/2012: Invensas on LRDIMM design inferiority vs. HyperCloud UPDATE: 07/27/2012 - confirmed HCDIMM similar latency as RDIMMs UPDATE: 07/27/2012 - confirmed LRDIMM latency and throughput weakness RDIMMs have a 1 cycle latency compared to UDIMMs (unregistered DIMMs). LRDIMMs have a 5 ns latency penalty compared to RDIMMs (from Inphi LRDIMM blog)

Based on 27,304 user benchmarks for the G.SKILL Trident Z DDR4 3200 C16 2x8GB and the Trident Z DDR4 3600 C16 2x8GB, we rank them both on effective speed and value for money against the best 113 RAMs In DDR3 vs DDR4 RAM comparison DDR4 clearly wins the speed round. Latency: Another change has made to the latency as well. Latency also affects the clock speed. The DDR3-2133 comes with a latency around 55 nanoseconds whereas the DDR4-2133 has a latency around 63 nanoseconds. While there is a small increase in latency but more is better than less ***Best Pick For Motherboards- OLOy DDr4 16GB 3200 MHz Ram Kit*** The CAS Latency Difference of Both Ram. Both Rams come with better CAS latency that makes sure good performance but in different ways. They tend to have dissimilar memory latency and identical speed at nanosecond measurement. Yet, one Ram has better CAS latency than another In our case, the ddr4 3200 has a higher frequency of up to 3200MHz and a 16 CAS latency, which is lower than ddr4 3000 RAM's 17 CAS latency and 3000MHz frequency. This means, the ddr4 3200 memory module will yield more improved performance, especially for gaming purposes Low-latency DDR4-3000 does drop away a little, To wrap this up, we suspect for most 3rd-gen Ryzen processors a 1900 MHz Infinity Fabric clock speed is going to be a bit too much

What are Memory Timings & How they Work: CAS, RAS and tRAS

  1. The memory kits in this category offer a 3600 MHz clock with a CAS Latency of 16 - making them perfect for any Ryzen build. Of course, the performance improvement you get will depend on your specific workloads. However, if you want the best performance at a great price, this is it. G.Skill Ripjaws V Series 16GB (2 x 8GB) DDR4 3600 MHz CL1
  2. Latency, on the other hand, is typically the delay period from when the RAM is issued a command to the time it responds. DDR4 3200 memory kit, for instance, has a CAS latency that ranges between 14 and 16 while the memory rated to 3600 ranges between 15 and 19. If both have the same latency, the DDR4 3600 RAM will be much faster than DDR4 3200
  3. g
  4. It's a little bit faster. If the computer/board supports it, and you can afford the faster memory (from a reputable memory supplier/brand), and more of it (say 8GB or 16GB, if the board supports it, as opposed to 2GB or 4GB), it could be a mild-to..
  5. It would be a matched pair with the same CAS latency and would be cheaper or buy a matched pair of 2400. Actually no DDR4-3200 is available in market right now. I have checked in Flipkart and Amazon

3200MHz vs 3600MHz DDR4 RAM, does it make a difference? Sign in to follow this . You guys mentioning CAS latency (CL) -- good on you -- because that has traditionally been a lot more important than 400 mhz difference in RAM clocking, in terms of sim performance Rated PC4-28800 / 3600MHz at CAS latency 16 and sure, this has to be one a great looking memory kit, yes even without RGB, due to its all-dark design. T We test this kit, their DDR4 3600MHz CL16. As many have mentioned for best speed compatibility yes same model + brand. As others have mentioned You can't put DDR3 in DDR4 (different slots). As others mentioned you can if you want mix and match for an Ideal mix and match: Same Speed, Size a.. Nothing has changed, as DDR3 memories, DDR4 memories does not differ much considering different cas latency and/or frequency. Further, all memory brands have more or less the same quality. IMO, it might have some significant difference in professional competency by using LN2, I'm not that sure, though When shopping for computer RAM you'll likely notice that in the specifications for each is a CAS (Column Access Strobe) Latency number, like CL16 on many 2666MHz DDR4 RAM kits.. Basically, the CAS latency, or CL, is an indication of the time it takes for your memory controller to get a particular piece of data ready to access from the RAM, so lower numbers are generally more desirable

TEAM XTREEM ARGB 16GB DDR4. With a CAS latency of 14, the Team Xtreem kit leads the way in low-latency RAM favoured by gaming PCs, especially AMD Ryzen rigs. As such, it takes the top spot as our pick for the best RAM for gaming. Not all that long ago a kit as well-rounded on both price and performance would've been a distant dream G.Skill also offers 2800, 3000 and 3200 MHz DDR4 with CAS 15 latency, but the price really goes up. In this situation I think I would go for the 2800MHz at CAS 16. The overall transaction turn-around is going to be very similar between the two, only precise benchmarking tools will be able to tell the difference and the 2800MHz RAM should deliver a little faster throughput on large transfers Mixing DDR4 with different CAS latency/timing? Greetings, I'm hoping to mix two sets of RAM with completely identical specs aside from CAS latency/timing. Voltage, speed, size are all the same. 2x4GB, 2400, 1.2v. The set I have has 16-16-16-36 and the set I'm hoping to add has 15-15-15-35 Ultra-Efficient 17-17-17 CAS Latency. Following the DDR4-4266MHz kit, are memory kits running at DDR4-4000MHz and DDR4-4133MHz in both 16GB (2x8GB) and 32GB (4x8GB) configurations, all at an ultra. DDR4 DDR3-2133 1067 Mhz 15 cycles 14.06 ns As you can see, the DDR4 at CAS 15 has 45.8% higher latency (14 ns vs. 9.6 ns), as can clearly be seen in the chart in the review. For this test we took Intel's most recent high-end i7 processors from the last five generations and set them to 3.0 GHz and with HyperThreading disabled

It took DDR3-2133 to simply equal DDR2-1066, and PCWatch estimated we'd need DDR4-4266 to match the latency of DDR3-2133. This chart is a bit old now,. low latency ddr4, Note that when we say true latencies are remaining roughly the same, we mean that from DDR3-1333 to DDR4-2666 (the range of current memory), true latencies started and ended at 13.5ns. While there are several instances within this range where true latencies increased, the gains have been by fractions of a nanosecond Best DDR4 Ram Reviews From Kingston, G.Skill, And Corsair the choice of ddr4 is not a simple matter.
