This fact falls within what is called memory overulsing and depending on how "we tighten" it said timmings would require a series of changes to other parameters related to intrins.
In any case, all the prices we will touch will take time and not money, in which case we must assess the strength of every step we make to make sure everything is correct.
Overclock RAMs in basic timmings
When looking at RAM information, we always find four or five values that determine specific access times. As an example on the Corsair Viveance RGB DDR4 3200 MHz, this is it 16-18-18-36-2, where the first value is known as CAS, the second as tRCD, third as tRP, fourth as tRAS and fifth as CR.
They have other names based on their acronyms, such as Command Rate, RAS Precharge or RAS in CAS Delay, so according to your motherboard manufacturer it can be found somewhat. Even in the most recent and current formats, it is possible that you only get 4 of these timmings, since tRCD and tRP in most cases are combined in one value.
If you want to know more, we have already talked a lot about them on this particular topic of these symptoms. To understand the overlap of these intervals, it is necessary to divide into four blocks that are usually very close to each other:
- CAS (or CL as we like to call it).
- tRCD with tRP, usually requires the same value.
- TRAS, excellent performance or durability is usually achieved with CL + tRCD + tRP
- CR
The four blocks of time symbols are more or less related to each other, where their relationship depends on who we are comparing, but in compiling this list it is usually started by changing from top to bottom.
CAS
The main thing when talking about playing CAS is that it is usually the lowest value of all primaries. It is a delicate value and has a significant effect on the bandwidth of reading and copying memory in general, a decline that can have the effects of instability in two different voltages: memory controller and RAM volume itself.
Usually, below the serial voltage of RAM it is possible to reduce its value to one unit, which in our case and following the example of our memory may be reduced to CAS 15.
For the best chips we have in our memory to tolerate smaller or smaller timmings, so it's not a rule of thumb to lower the unit in CAS, but it usually works.
tRCD
It is a very important value, because after some time has passed in RAS the CAS starts working to authenticate you. Therefore, although it will always be larger in ensuring the robustness of the system, it should be taken with caution.
Some chips are able to lower the unit without problems, the other two (they still have stock issues), but in many cases it is even necessary to leave it as standard because it can cause instability. You will have to try how good our chips are in our RAM.
tRP
The option to join this time and tRCD by saying which motherboard was given is the fact that it will not work until the first one completes its task.
Therefore, they often have an equal working time and at this rate can be reduced to the same level as the tRCD.
You never see a tRP under a tRCD, so it's a third reduction.
TRAS
Its overulsing value is somewhat ambiguous to say and although there is a standard amount of CL + tRCD + tRP for the same amount or larger in all cases, there are chips that tolerate lower values of this figure.
It's not common, but it's been proven, so it's probably a valid option if our modules support it.
CR
This punctuality is very controversial in excessive placement. By touching modules and timmings alike, it is a global crowd that can pay attention to all the overlaps and is therefore always left to the last place and is thought to lead to action. Delete CMOS In some cases.
The 2T command is the most widely used in the industry, but some modules are able to function normally with 1T, in which case you should not touch anything because it is too low. If our modules are 2T, shrinking to 1T would require a large amount of power in RAM, and probably not as strong.
This is the case for our Vengeance RGB, where 1T is impossible to set without going to values above 1.45 volts, something that does not compensate us.
Fitness
In any case, the important thing is that with each value we change we make sure that we are fully stable with our RAM stability test and system choice. As always, we recommend RealBench because it is a real compression and not an actual output without CPU and memory parameters.
But if you're looking for something you really want in this field, you have our RunMemTest Pro or Karhu RAMTest notebook, which will make your memory go horribly wrong, but if they fail to provide errors, you can rest assured that your RAM is actually a stone.
