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.Unfortunately, the market for low-latency DDR4-2666 is so small that CAS 12 and CAS 13 kits are no longer being produced. CAS 15 timings appear to be the quickest of currently-available parts.

However, just because the DDR4-2400 RAM ... Jul 11, 2020 · The single most effective timing value to change though is CAS Latency or CL. CAS stands for Column Address Strobe, CAS Latency refers to the exact number of cycles between the RAM being sent a column address and the response with the first bit of data. A lower value means lower latency, but this is also reliant on the clock speed of the RAM. ...PC RAM DDR4 rank, speed, CAS latency, capacity, number of modules, how to upgrade your RAM, how to properly install your RAM, how to optimize your RAM, XMP vs [Simple Guide] Does RAM speed REALLY matter? Ram Speed Vs Cas Latency - Which Affects Gaming More For Ryzen 3000?Jul 13, 2018 · Memory frequency have always been getting fast, but it has been at the cost of latency, I remember having some fast DDR2 Kingston HyperX 800mhz running at CAS4, now I see fast DDR4 running at 4 times the frequencies, but they are also running at 4 times the latency, its clear that frequency is the larger factor when it comes to performance.
Jul 25, 2019 · 1. DDR4 3733 MHz – Absolute best performance . From the horses mouth itself, AMD has claimed that 3733 MHz CL17 is the fastest RAM speed Ryzen 3000 processors can support without issues with latency and the controller. Mar 31, 2008 · The slightly higher cas latency on the 1066 will be offset by the higher frequency. I would go with a slightly lower CAS latency, and a higher ram frequency myself. As the speed of the chips keep increasing, the importance of CAS latency timing is dropping. This is why I think you will be smarter going with a higher frequency chipset. 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.
The actual equation is more complex, but this simplified equation allows us to compare the latency of different memory products. In this case: 16/3200 = .005 and 18/3600 = .005 so the primary latency of these two RAM modules would be the same, but because the 3600 modules run at a higher clock speed, they provide more bandwidth. Though DDR4 RAM is updated with higher storage density and power efficiency than DDR3 RAM, its CAS latency tends to be higher. The CAS latency for DDR3 RAM is typically 9 or 10, while the CAS latency for DDR4 is at least 15. However, due to its faster clock speed, newer standards have better overall performance. Conclusion 1.3 - Addition of DDR4-2666. 1.4 - Correct typo in Key features. - Update Input/output functional description. - Update Timing parameters by speed grade. - Add Rounding Algorithms. - Add The DQ input receiver compliance mask for voltage and timing. Speed. tCK(min) CAS Latency.
Jan 20, 2020 · DDR4 memory sticks consume less power than their DDR3 equivalents, but their latency is also a little higher. In theory, this means response times will be slower, but DDR4’s increased speeds ... With such high-speed DDR4 RAM in the market, people argue about what makes RAM performance better? Here is DDR4 RAM speed vs latency explained. But DDR4 memory is still good and will be good for a while. People often argue what is a good DDR4 RAM, what affects its performance?
If you move beyond this, the motherboard will automatically set the Infinity Fabric clock to 1:2, or half the memory speed. This incurs a latency penalty that we see in the data, with DDR4-3600 ... Sep 17, 2015 · The following CAS latencies were used for each speed grade: Memory clock DDR3 CAS latency ... One crucial thing to point out with DDR4 is that it has an oddball “CAS latency hole.” You’ll ...
Sep 15, 2019 · Speed, Timings, and CAS Latency. RAM speed is generally measured in megahertz, usually abbreviated as “Mhz.” This is a measure of the clock speed (how many times per second the RAM can access its memory) and is the same way CPU speed is measured. The “stock” speed for DDR4 (the newest memory type) is usually 2133 Mhz or 2400 Mhz. ram speed vs cas latency ram speed vs cas latency. By ... Gaming laptop: Asus FX503VD, i5-7300HQ, DDR4 2133 2x8GB, GTX 1050, Sandisk 256GB + 480GB SSD ...
DDR2, DDR3, and DDR4 still use a double-pumped 64-bit memory bus (transferring data on the rising and falling edges of the clock signal), not quad-pumped. Running the FSB at the same clock speed as the memory can reduce latency by avoiding buffering between clock domains. So yes, the CAS...
CAS latency explained. Column Access 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.
Nov 27, 2020 · The Ballistix 3600MHz DDR4 RAM kit is perfect for high performance in gaming and non-gaming operations as it features a low CAS Latency of 16-18-18-38 operating on 1.35V. Some users are able to achieve even higher frequency like 3800MHz with the same timings which resulted in performance boost as the latency is still the same.
With such high-speed DDR4 RAM in the market, people argue about what makes RAM performance better? Here is DDR4 RAM speed vs latency explained. But DDR4 memory is still good and will be good for a while. People often argue what is a good DDR4 RAM, what affects its performance?Latency is best measured in nanoseconds, which is a combination of speed and CAS latency. Example: if the speed rating of a standard module and a gaming module is the same (i.e. DDR4-2666) but the CAS latencies are different (i.e. CL16 vs. CL19), then the lower CAS latency will provide...
Jul 06, 2020 · DDR4 RAM speed vs latency, which one to look out for the most. The answer to that is a bit complicated than just declaring one of these the winner. To be honest, both of these factors matter ...
Semiconductor engineers know that CAS latencies are an inaccurate indicator of performance. Latency is best measured in nanoseconds, which is a combination of speed and CAS latency. Both speed increases and latency decreases result in better system performance. Example: because the latency in nanoseconds for DDR4-2400 CL17 and DDR4-2666 CL19 is roughly the same, the higher speed DDR4-2666 RAM will provide better performance. Latency is measured in cycles cycle time is the inverse of frequency so that both DDR4 3600 CAS 18 and DDR4 2800 CAS 14 have the same ten nanoseconds of real time latency as DDR4 3200 CAS 16. 0 RAM can cost up to twice as much as CAS 3.

I vaguely remember RAM latency being important But there are a lot of factors regarding it. I believe, and I may be wrong, that cas 16 DDR4 -3200 performed on par with CAS18 DDR4-3600 in Zen 2. When it comes to Ryzen lower latency is generally best. Even better is higher speed with low latency.Speed - DDR4-2400 Warranty - Manufacturer's Limited Lifetime CAS latency - 17 DRAM family - Crucial Density - 32GB Kit (16GBx2) Brand - Crucial ... RAM speed vs. RAM latency. While a RAM's data transfer rate tells you how many mega transfers (1,000,000 data transfers) the RAM can do in one second (a DDR4-3200 RAM can conduct 3,200 mega transfers in 1 second), its CAS latency is also important for understanding RAM performance.
