Merchant … Form Factor. 32GB (2x16GB) Corsair DDR4 Vengeance LPX Black, PC4-21300 (2666), Non-ECC Unbuffered, CAS 16-18-18-35, XMP 2.0, 1.2V is rated 4.6 out of 5 by 5. i actually picked the Ryzen 5 3600 for my CPU. CAS Latency. As such, it takes the top spot as our pick for the best RAM for gaming. These are the best, cheapest low profile sticks should you want B-die, 3600 MHz and CL16 for Ryzen 3000 processors such as the 3600, 3700X, 3800X and 3900X. another way to look at it is 2133 divided by 15 and 2400 divided by 17 = about the same latency but the later will have a bit more bandwidth. 288-pin DIMM Modules. Form Factor. 16 Voltage. which should i buy? 4 x 16GB Color. ECC / Registered. 1.35 V Voltage. I want a set of RGB RAM but the CL-16 memory is an extra $25 Canadian. And the 2800MHz ram is 5% higher bandwidth. Non-ECC / Unbuffered ECC / Registered. Thus, when comparing a stick of DDR4-3000 RAM with a CAS of 15 and a stick of DDR4-3600 RAM with a CAS of 18 (which would both have a true latency of 10 nanoseconds), the DDR4-3600 should be preferred. The CAS rating is the number of cycles it takes to perform the Column Address Strobe. But 2800MHz is 5% faster than 2666MHz. Non-ECC / Unbuffered ECC / Registered. Tags: CAS latency, latency, RAM, RAM speed, true latency, Guides to the best PC builds for any budget at logicalincrements.com. The order of the numbers tells you their meaning. I'm running 64 GB Hynix E Die right now at Cas 16 with slower secondary timings and latency is just barely worse than the B Dies at 3600. Therefore, a stick of 8GB RAM with a clock speed of 2666mhz can process 8GB of data at a given time, and 2666mhz is the speed at which the information will be processed. But CL cannot be considered in isolation. latency is a thing of the past .. if you can run it at T1 command rate, that's all you need. 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. £4.768 Color. 1.35 V Voltage. DDR4-3200 , 16 CAS Latency vs DDR4-3600, 18 CAS Latency? Corsair Part # CMK16GX4M2B3200C14R. Timing: 16-18-18-38. DDR4-2666) but the CAS latencies are different (i.e. 16-18-18-36 Timing. I think with PBO it overvolted my 3700x a bit too much and degraded the chip .. now , the memory can still run the same ..but 1800 is max on fclk (PBO disabled). Mobile Phone. in … View Compatible Motherboards; Prices. Vegeance RGB Pro SL vs Vegeance RGB Pro? In above illustration the CAS Latency Ratio is 16. i plan on upgrading/building a better pc after another year or two when i get to know more about PCs. Those new micron chips play well with the Ryzen CPUs. Timing 16-18-18-38 CAS Latency 16 . This is why adding more RAM will not necessarily make your computer faster: you’re adding more lanes to the road and more car capacity, rather than increasing the speed limit. Crucial Part # BL2K8G36C16U4B. Yes Heat Spreader. Yes Heat Spreader. CAS Latency: 16; Voltage: 1.35V; Timing: 16-18-18-36; Recommend Use: AMD 300 Series / AMD 400 Series / AMD X570 / Intel 200 Series / Intel 300 Series / Intel 400 Series / Intel X299; Model #: CMK16GX4M2B3200C16; Item #: N82E16820233859; Return Policy: Standard Return Policy; $98.00 $89.99 – Save: 8%; Free Shipping; Shipped by Newegg. the extra 200MHz won't make that much difference especially at the cost of latency. But CAS does not exist in a vacuum, and must be put into a formula alongside other specifications in order to determine the true latency of your RAM. CAS Latency, tRCD, tRP, & tRAS (Pt 1) ... the 16-18-18-36 Corsair kit somehow outperformed the 14-14-14-34 G.SKILL kit in tests. 16 Voltage. Speed / CAS latency = value The higher the number you get for “value”, the better. Posts: 454 Joined: Thu Dec 30, 2004 5:50 am Location: Ottawa, Canada. 3333 (speed in MHz) / 15 (CAS latency) = 222. Compare (40) Crucial 8GB 288-Pin DDR4 … RAM Latency (timings)Test - CL 14 vs CL 16 vs CL 18 , 3000MHz RAM, AMD Ryzen.Test Detailslow detail settings used @ 1080p.Radeon 19.12.3 driver used. Kingston HX424S14IBK2/16, 16GB 2400MHZ DDR4 CL14 SODIMM (KIT OF 2) Hyperx Impact $226 would provide the best cpu performance but its half as much ram if you had another use for the system outside of gaming that actually needs it However, a quick perusal will reveal that there’s over a hundred variants of 3600mhz RAM available. Manufacturer. Non-ECC / Unbuffered Heat Spreader . Am I right in thinking that the numbers we hear for memory timings are all in multiples of clocks? Passing chunks of data from one place to another takes time, so latency builds up at every step of the streaming workflow.The term glass-to-glass latency is used to represent the total time difference between source and viewer. If your motherboard and CPU is only rated up to 3600mhz, then you should only purchase or overclock RAM up to 3600mhz. I had it at 3733 for a while at Cas 16, but it took 1.47v. It takes the data rate (MHz) and cas latency (CL), then calculates the absolute latency for memory accesses in nanoseconds. The size of your RAM, in this analogy, would be how many cars each lane can hold. 1.35 V Voltage. Re: Ram speed vs … Let us use a busy highway as an analogy. Non-ECC / Unbuffered Heat Spreader. Yes Heat Spreader. 18-22-22-42 Timing. Cookies help us deliver our Services. 8GB (2x4GB) Corsair DDR4 Vengeance LPX Black, PC4-21300 (2666), Non-ECC Unbuffered, CAS 16-18-18-35, XMP 2.0, 1.2V is rated 4.9 out of 5 by 7. Moreover, two different RAM kit may have the same data transfer rate. Manufacturer. Retailers list timings as four numbers separated by dashes, like 16-18-18-38. 16 CAS Latency. 2 x 16GB Price / GB. 1 clock is 1.25ns, so CAS 5 is 5 x 1.25ns = 6.25ns ? Non-ECC / Unbuffered ECC / Registered. Compare #1 Best Seller. If I had to pick between the two, I'd get the 3600 kit and run it at 3200 as tight as I can. For example, the G.Skill Ripjaws V DDR4-3600 with a CAS of 19 costs about $130 USD. Ryzen 3000 memory speed vs latency in gaming. Non-ECC / Unbuffered ECC / Registered. White First Word Latency. which is better? CAS Latency. If you tell someone to “duck!”, CAS latency would be the delay between when you command them to duck and when the other person reacts. This incurs a latency penalty that we see in the data, with DDR4-3600 generally being slightly faster than DDR4-4000. Latency, on the other hand, is typically the delay period from when the RAM is issued a command to the time it responds. Feb 20, 2019 #1 Maybe this boils down to components being used (listed below) but I supposed my question is as follows - … Share Facebook Twitter Google Reddit Pinterest LinkedIn WhatsApp. 16-18-18-36 Timing. CAS Latency: 16; Voltage: 1.35V; Multi-channel Kit: Dual Channel Kit; Timing: 16-19-19-39; Model #: F4-3600C16D-16GVKC; Item #: N82E16820232880; Return Policy: Standard Return Policy $97.99 – Free Shipping; Shipped by Newegg. Thus, when comparing a stick of DDR4-3000 RAM with a CAS of 15 and a stick of DDR4-3600 RAM with a CAS of 18 (which would both have a true latency of 10 nanoseconds), the DDR4-3600 should be preferred. When dealing in nanoseconds, the difference may not seem significant—and it can certainly be argued that, for the average user, the difference between a CAS of 15 and a CAS of 19 is not worth breaking the bank. 85 posts; 85 posts; Location: United States; Posted August 30, 2019. This is where the constraints of your budget must do battle with your desire for speed (as well as any aesthetic considerations such as RGB lighting). With the RTX 2080 Ti we see an 18% boost for the manually tuned DDR4-3800 over the low-latency CL14 DDR4-3200 memory. 5% more cycles pass in the same time frame with the 2800MHz ram so the 6% deficiency in latency is reduced to 1%. i picked out the CPU, GPU and other parts. It seems to indicate that the RAM with 3200Hz and 14 latency performs better since the calculation is lower. Non-ECC / Unbuffered Heat Spreader. You will see a list of timing on the RAM like CL16-18-38 and CL14-14-34. CL16 vs. CL19), then the lower CAS latency will provide better performance; The difference between the perception of latency and the truth of latency comes down to how latency is defined and measured. 1.35 V Timing. CAS Latency. Yes Heat Spreader. If your going for 3200mhz, try to look for 16 CAS Latency or lower.
