The computer reads information by searching its coordinates within rows and columns. thanks!! Posté le 29-08-2018 à 12:41:45 . 14. The CAS latency is also called CL. DDR4-2666) but the CAS latencies are different (i.e. 3400 (speed in MHz) / 16 (CAS latency) = 212. 2133/13 = 164 2400/14 = 171.42 Higher is better in this case so the 2400mhz CL14 modules not only offer more bandwidth than the 2133mhz modules they are also lower latency overall by around 3-4% Meaker@Sager, Nov 3, 2017 #3. For example, here is a comparison of two RAM kits, one with 3333MHz and C15 and the other with 3400 MHz and C16. CAS latency can be referred to in several different ways. 1 of 2 Go to page.

This also goes for two RAM modules with the same CAS latency and different frequencies; the RAM chip with the higher frequency will be preferable. Gerbil … Message édité par chermositto le 29-08-2018 à 12:52:00. This is a relatively narrow range which indicates that the Corsair Vengeance LPX DDR4 2400 C16 1x8GB performs reasonably consistently under varying real world conditions. Thread starter cucker tarlson; Start date Oct 3 , 2019; 1; 2; Next. It takes the data rate (MHz) and cas latency (CL), then calculates the absolute latency for memory accesses in nanoseconds. spiritwalker2222.

Specs. 14-15-16-36. (3200Mhz, 16 CAS) If all are the same price, go for either the 3000 or 3200Mhz option. 5% more cycles pass in the same time frame with the 2800MHz ram so the 6% deficiency in latency is reduced to 1%. Top . Latency in seconds = (1/(clockspeed))*(CAS latency) (1/2400000000)*14 = 5.83 nanoseconds latency. Cello. Specifically, CAS latency is measured in clock cycles, so these new memory kits from G.SKILL can complete a specific test used for measurement within 14 clock cycles. Next Last.

How much of that 12.5% you will see will depend on to many factors to give a definitive number. 16 is the “Row pre-charge … The lower the CAS latency, the better. First number: CAS Latency (CL) The time it takes for the memory to respond to the CPU is the CAS latency (CL). I haven't been able to demonstrate any truly meaningful performance gain going from 16-18-18-38-2T to 14-14-14-34-1T, so I very much doubt my results are suddenly going to get a lot better at 13-13-13-30.

Newegg shopping upgraded ™ Retailers list timings as four numbers separated by dashes, like 16-18-18-38. Caractéristiques techniques Type de RAM : DDR, DDR2, DDR3, DDR4 Chaque carte-mère ne gère en général qu'un seul type de mémoire , c'est le contrôleur mémoire de la carte-mère qui décide. While both RAM chips might be 3200mhz, they can have different performances if one has a CAS latency of 14 and another has a CAS latency of 16, with the C14 performing better and faster than the C16 despite having the same frequency. Au dessus de 3200, je ne pense pas qu'il y ait de gain. cucker tarlson. The theoretical difference between Cl14 3200 & cl16 3200 is 12.5%. Color: Black.

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. "Previously, the best CAS latency that memory kits at the DDR4-4000 level could achieve was at CL17. Pour faire un peu de tout :D: Du 4 k low cost. chermositt o. Posté le 29-08-2018 à 12:46:35 . Joined Aug 6, 2017 Messages 7,412 (5.71/day) Location Poland System Specs. CAS (Column Access Strobe) latency refers to the delay time between the READ command and the time data gets available. Based on 3,539 user benchmarks for the G.SKILL Trident Z DDR4 3200 C14 4x16GB and the Trident Z DDR4 3600 C16 2x8GB, we rank them both on effective … This is the time required to start responding to given commands. La vitesse de sédimentation peut varier en fonction de certains facteurs : l’âge : elle augmente avec l’âge, après 45 ans ; la grossesse : l’augmentation de la VS est liée à l’hémodilution (dilution du sang liée à … help me! (2400Mhz DDR4 with 14 CAS) (1/3000000000)*15 = 5 nanoseconds latency. Example: if the speed rating of a standard module and a gaming module is the same (i.e. Column Address Strobe (CAS) latency, or CL, is the delay in clock cycles between the READ command and the moment data is available. Achetez votre Mémoire G.Skill Trident Z Neo DDR4 2 x 16 Go 3600 MHz CAS 16 Ryzen Edition (F4-3600C16D-32GTZNC) sur Materiel.net ! Also as a side note 3200mhz cl16 will have almost exactly the same latency as 3600mhz cl18 (you can calculate the difference between ram kits by dividing memory frequency by cas latency and comparing the result, 3600/18 is equal to 3200/16) RAM Latency performance comparison - CL 14 vs CL 15 vs CL 16 3000MHz RAM. This is a RAM latency calculator. But CL cannot be considered in isolation. Timing 14-14-14-34 CAS Latency 14 . [HELP] Quel upgrade? The CAS rating is the number of cycles it takes to perform the Column Address Strobe. You will see a list of timing on the RAM like CL16-18-38 and CL14-14-34. 16. I've asked this question in chats and I know the difference may be negligible in real-life (or maybe it isn't) and people say it's no big deal. La latence CAS (CAS Latency (CL) en anglais) correspond au nombre de cycles d'horloge précédant l'acheminement des données après la réception d'une commande, ce délai dépend du temps de réaction interne. 15. As previously mentioned, CAS Latency (CL) is the best known memory parameter. It tells us how many clock cycles … RTX 2070 ? Bandwidth will always go up with frequency, you can work out a rough guide to latency by diving the speed by the CAS latency. 15 is the “Row address to column address delay” (tRCD) which means the latency between reading the row number to the column number. Publicité. DDR4 3200 (PC4 25600) Timing 14-14-14-34 CAS Latency 14 Voltage 1.35V; Overview. 3200 cas 16 c'est bien. Smaller numbers are faster. And the 2800MHz ram is 5% higher bandwidth. The order of the numbers tells you their meaning. CAS * 2000 / Speed(in MHz) If you take the last entry for example; the result is as follows: 18 x 2000 / 2666 = 13.50337 Or from the DDR4 2400 entry: 17 x 2000 / 2400 = 14.166666 So my original equation (1st post) is actually a calculation of "true latency", not true speed: (as I now learned) At least I'll be able to use the equation to determine if my RAM upgrade is really an upgrade. Latency is often misunderstood because on product flyers and spec comparisons, it's noted in terms of CAS latency (CL), which is only half the formula for calculating latency. CAS Latency: 14.
