They could run this value memories with very tight timings at 2667mhz.I choose 2667mhz and i the timings in the review didn't work so i typed Auto in the all the Dram settings and i typed a new voltage in memory voltage manually 1.35v.The timings are pretty high 18-18-18-44 1T but in the review is 2T.So i thought maybe 1T is too much but i realized that the board don't have the option for change.. First up is the influence of the Command Rate setting, it's a comparison of results using the 1T and 2T. We use our normal gaming tiles with normal image quality settings like you use them at home...
Won't notice a difference unless you use intensive applications, you can use either 1t or 2t depending on ram compatibility. I have my RAM at CL14 and 1T We've checked the impact of the Command Rate when the 1T/2T were used (the frequency was 3200 MHz CL14-14-14-34).

Feb 7, 2013 #1 So been out of the loop on memory overclocking but back from the DDR1 days, memory that ran at a lower frequency but with a command rate of 1T was either on par or faster. Command Rate: What Are The Benefits Of 1T? Command rate is the number of cycles a command must be presented before a memory operation commences, so that 2T incurs an additional cycle of latency to. . Hierzu konnten wir 3.733 MHz mit den Timings CL16-18-18-23 fixieren, wodurch die Speicher-Bandbreite mit 39,42.
AMD defines the Command Rate as the amount of time, in cycles, between when a DRAM chip is selected and a command is executed. It is either 1T or 2T, where 2T CR can be very beneficial for stability with higher memory clocks or for 4-DIMM configurations. CR is sometimes also called Command Period. While 1T is faster, 2T can be more stable in certain scenarios. It is also measured in clock. . Dabei handelt es sich um Wartezeiten des Speichers. Je mehr Bänke bestückt sind und je Höher der SpeicherController belastet ist desto schwerer wird es die kleinere wartezeit 1T einzustelle
[quote name='evil' date='Sep 18 2005, 03:24 AM']1T is recommended for ECC memory, Error Correcting Dimms/Buffered memory. 2T is recommended for unbuffered memory (Standard Memory Dimms) Some can get away using 1T on Unbuffered memory if they don't leave their computer running 24 hours a day like I do. If you shut your computer off nightly, 1T would not be that risky. [post=50086][/post] why is this so ? I am running 1T running 2/7 on my Athlon X2 4200+ Using MSI K8N SLI Plat as for my. Performanter ist sicher 1T statt 2T. Die Frage ist nur, ob es dein Equipment mit macht; hängt auch von den sonstigen Timings und Frequenzen ab. Es gibt da keine generelle Empfehlungen, da auch. When using dual-rank modules or populating all 4 DIMM slots it should force you to use the 2T command rate. There is a bug in the latest uCode that lets you run at 1T command rate just on the.

My 8g of Mushkin (2x4) RAM has 6-8-6-24 timings at 1600Mhz. I just changed the command rate from 2T to 1T and ran a few tests for the past couple of days and all seems very well. As far as objective analysis goes, what is the common performance measurement difference between the two? Anyone know?.. . This is a huge difference in memory bandwidth and the Command Rate setting definitely impacts performance test results on Socket 939 motherboards. All AnandTech benchmarks were run at a Command Rate setting of 1T. This includes all benchmarks that were run in the CPU tests, as all. Since I run my RAM at stock I've got the command rate set to 1T without any problems but if your mobo / OC isn't happy with it, then it's no great loss at all. A stable OC at 2T will possibly provide more of a real world gain. Last edited: 18 Mar 2010. Trust. 18 Mar 2010 at 20:20 #7. ChrisLandin . Wise Guy.

Obviously, 1T is better, than 2T, if your system can handle it. This is a common name for the 1T / 2T parameter amongst bios manufacturers, but is rather misleading as it does not mean the number of commands that are executed each clock cycle as its title would imply
Command rate (CR) The amount of time, in cycles, between when a DRAM chip is selected and a command is executed. 2T CR can be very beneficial for stability with high memory clocks, or for 4-DIMM configurations. 2T, 1T: ProcODT (CPU on-die termination) A resistance value, in ohms, that determines how a completed memory signal is terminated. In this analysis, intended to show the affect of 1N versus 2N Command Rate, we see that setting 1N (DRAM Command Rate to 1T) can improve synthetic memory read scores by as much as ~3.3% over 2N Crucial Memory Speed vs Latency: http://www.crucial.com/usa/en/memory-performance-speed-latency. Note there wasn't time to cover command rate (1T vs 2T) in this video. If possible try to get memory with a command rate of 1T for now. Working on something special for that! :D ***** Thanks for watching our videos! If you want more, check us out online at the following places However, what I would do to run my memory at a 1T command rate, would be to run the CPU's FSB at a 1:1 ratio with the memory speed. This would effectively run the memory between 667Mhz to 800Mhz or more depending on if you have your system OCed or not. Once running the memory at the lower frequency, I would then set the command rate to be 1T instead of 2T
If you are running 1T, you can try 2T it helps a lot but you loose some latency since your CPU send twice the command instead of once. And depending on your chips, you might also need to use something higher then 1.35volts, maybe 1.4 or 1.45, it is still safe even if many people think it's not As for 2T vs 1T, 1T should always be run with Geardown on unless you're chasing that elusive bench result that's 0.3ns away. It's an AMD exclusive and essentially gives you close to 1T performance while not requiring much more voltage than 2T. What VDRAM are you running currently? No reason why 3533 16-17-17 at loose timings should be unstable 1T GDM unless you're trying to run like 1.2V CR (Command Rate): This means the number of consecutive clocks required when a memory controller sends commands to a memory bank. The CR is indicated as 1T or 2T (often 1N or 2N), each means one clock and two clocks. If the CR is 1T, each of the commands are sent only once to the memory bank which takes one clock (therefore, one clock delay. While it is enabled, setting the command rate option for memory timings is pointless; it will always effectively be 2T (although the company notes it's not quite the same thing—1T versus 2T. ♦ 2667mhz (16GB)CL16-15-15-15-39 Command Rate 1T All sub-timings manual set ♦ 3400mhz (16GB)CL16-18-18-18-36 Command Rate 1T All sub-timings manual set ♦ 3466mhz (16GB)CL14-14-14-14-28 Command Rate 1T All sub-timings manual set Ryzen Memory Tested Is It Worth Buying New Faster Ra

Für Übertakter auch interessant ist die Command Rate (1T/2T), obwohl diese Latenzzeit des Speicherchips keine isolierte Eigenschaft ist. Diese Wartezeit wird dann nötig, wenn viele Chips am Speicherkanal aktiv sind und dadurch die Adressleitungen des Speichercontrollers stärker belastet werden. In der Regel lassen sich bis zu 3 Ranks (ein Double-Rank und ein Single-Rank) mit 1T ansprechen. Command Rate 1T/2T [can now be set manually] What the difference between T and F BIOS? Which should I use? T BIOS are test versions. They include tweaks our R&D team are experimenting with. They are likely less stable and may contain features/settings that never make it to a final version. Only use if you are comfortable adjusting advanced BIOS settings. F BIOS are beta versions. They. Our data points indicate that Geardown Mode should be disabled for gaming if you can achieve your desired memory overclock with a 1T command rate. The opposite holds true if 1T CR proves too aggressive to reach your desired clockspeed--leaving Geardown Mode enabled may get you there. Finally, when it comes to GDM vs. 2T CR (not shown), specific memory throughput testing should be conducted as.
The last one CMD (Command Rate) is less important these days due to an increase in memory frequency. It refers to the time it takes between having the first command sent to memory and when it was activated. It is usually either T1 (1 clock cycle) or T2 (2 clock cycles). If none of that makes real sense, that is fine because it is a large topic on its own. I would suggest reading the Wikipedia. Having a tigher CAS Latency (CL) or Command Rate (CR)? CL20@1T Vs.

Feb 2, 2021 #2 If you're working with an AMD Ryzen platform, the tighter timings will be a better idea for the platform. If it's an Intel platform and your chipset can handle higher frequencies, then you should look at higher. Now, 1T means it takes 1 clock cycle to find a memory bank, vs. 2T where it takes 2 clock cycles to find the memory bank. But there's a sorta quirk, this only happens the first time data is attempted to be fetched from memory, and all subsequent accesses to that chip are done w/o delay, making the command rate null after the initial chip fetch As 1T command rates can be beneficial (though tough to maintain) for performance, the chart below is really asking whether it's useful to run GDM if the desired memory clockspeed can be achieved. source If you enable GDM and 1T, then a 1T command rate can be ignored. 0 CountMike Titan.

The same Corsair memory was running at a 1T command rate on the AMD system while we had it set to 2T on Intel. (This was simply a result of out-of-box settings with this memory on each platform. It allows DRAM to run at half of its specified frequency above DDR4-2667 when storing values on the memory module's command or address buses (this is known as latching). According to AMD's tests, the difference between GDM on versus off isn't very significant. If you can hit your desired overclock with a 1T command rate, turning GDM off will improve your performance. If yo The fourth (t RAS) is often omitted, or a fifth, the Command rate, sometimes added (normally 2T or 1T, also written 2N, 1N). These parameters (as part of a larger whole) specify the clock latency of certain specific commands issued to a random access memory. Lower numbers imply a shorter wait between commands (as determined in clock cycles) AMD Ryzen DDR4 overclocking gaming performance: timings vs frequency Posted on Saturday, Jul 15 2017 @ 14:09 CEST by Thomas De Maesschalck As we know, the AMD Ryzen platform's memory compatibility and overclocking support has improved quite a bit since the early March 2017 launch date Except for the processors and motherboards, every piece of hardware used for each setup is the same. CPU - Memory - VGA : Setup. The RAM speed used is CL15 XMP, but I'd like to make a point that I'm unable to set the same Command Rate (CR) timing for both CPUs because the Ryzen system defaults to 1T and we can't change it, but on the Intel system it's running on 2T by default on.

When Ryzen launched, many reviewers noted the chip tended to compete extremely well against Intel in many tests, either in pure performance or performance-per-dollar. Ryzen gaming at lower resolutions like 1080p, however, was a weak spot in some tests. AMD promised that new BIOS (UEFI) updates and game patches would, over time, improve the performance Core i7-7700 vs Ryzen 5 3600 Destiny 2 Performance Ok, so only when i manually put in bios the frequency multiplier to 16 (1600mhz) i get in cpu-z Command Rate(CR) 2T, on any other frequency that is above that i get 1T in cpu-z basically lowering my ram stability.... https://ibb.co/vVNZBnN Update2: So yeah, i've tried to do auto subtimings and they went to 16-18-18-38, seemed more stable. Andersrum ist es aber eigentlich wirklich egal, ob die kleineren Ryzen/Threadripper nun deaktivierte Cores enthalten - oder wirklich nur die angegebenen Kerne enthalten. Klar Früher gab es schon mal ne Zeit als man nen AMD X3 zu nem X4 frei schalten konnte - aber das Risiko, dass es nicht klappt - oder eben zu sonstigen Fehlern (und damit meist Instabilitäten) führt, wäre es mir nicht wert
