So im thinking of adding extra cpu and see its supposed to work fine as long as same speed
But the question is with C16(speed?) Some are RBG others Xmp and so on .


Corsair Vengeance RGB PRO - Módulo de Memoria de Alto Rendimiento, 32 GB (2 x 16 GB), DDR4, 3200 MHz, C16 XMP, 2.0 RGB LED Iluminación, Negro

I want to save as much money as possible on ram by not upgrading to 2 x 32gb sticks

Extra CPU? You mean extra RAM (based on the rest of you post)

So, short answer: it seems your existing RAM and the new one are almost the same, thus compatible, but the new one just has funny LEDs on it to illuminate your PC.

RGB (Red Green Blue) RAM just means that the RAM had pretty LEDs for shining with colors. It says nothing about the technology, speed, latency etc of the RAM.

XMP is a technology to optimize RAM speed (a bit). If you never activated it in your BIOS you never used it. Your RAM is used in a standard manner.

Your new RAM will also used in a standard manner in this case.

If you activated XMP, both old and new RAM will be used to the best possible way by your BIOS. It's visible on benchmarks. In every day practice, it won't be visible most of the time. It can be on extremely RAM-demanding applications.

So, ATM, you have on your MB, if I look at the old posts (21 Jun 2020 12:41 PM GMT)
"Corsair Vengeance RGB Pro - Kit de Memoria Entusiasta 32 GB (2 x 16 GB), DDR4, 3200 MHz, C16, XMP 2.0 179€"

That's it or not?


If it's the case, it seems that what you want to add is almost the same model. So there should be no issue. The only difference I can see is that the model got flashy colors LEDS. They don't affect performance.

Now the details.

There are 2 main things about RAM: speed and latency.

Speed is about how fast data travels. This is what the "XMP" is about.
A DDR4-3200 RAM can do 3,200 million transfers (3,200,000,000) per second, etc. (This corresponds to a frequency of 3,200MHz which is another way to express RAM speed.)

Latency refers to the time the RAM needs to access a specific data stored and to make it available. A C16 RAM needs 16 clock cycles to find data.

Let's say that, if RAM was a librarian, latency is how long it takes the Librarian to find a book on the shelves, and speed is about how fast the librarian can run to bring the books to you once he has found them.


So about speed and XPM:

XMP -Extreme Memory Profile- is a technology that allows the RAM to be used at its best regarding speed, instead of just using an industrial pre-set speed. The pre-set values are standardized speeds that all memory manufacturers adhere to: it’s the DDR4-2133, DDR4-2400, DDR4-2666, DDR4-3000, etc. you see on catalogs. (This standard is called "JEDEC".)

To use XMP, you need to have a CPU, a motherboard, and of course RAM all designed to use this technology. It will be specified in technical info docs. Normally, most recent equipment's, except basic or some middle-range ones, will be compatible with XMP.

BUT MOSTLY, to use XMP, you need to have manually enabled it in the BIOS.

If XMP was not enabled (or your equipment not compatible with XMP), then your XPM RAM will just work as a non-XMP RAM, at the standardized speeds like DDR4-2133 etc. The "best" speed is usually picked by your BIOS automatically.

Using the fined-tweaked XMP over JEDEC doesn't necessarily translate into significantly better performance, as other things than the speed can vary positively or negatively, such as latency.

But usually it will be a bit better, at least on benchmarks.



So about latency:

C16 is a latency indication. "C" is an abbreviation for CL (Column Latency); "column" being the librarian's shelf where the books (data) are stored.

The number next to the letter C is how many clock cycles it takes to get data. C16 means the RAM takes 16 clocks cycles. You have C15 RAM that takes 15 cycles.



:twisted: So what in hell should I favor? High speed or low latency? :twisted:

Believe me, there are even more details... So let's be simple.

To know what the best choice between different RAMs is, divide the speed by the latency.

The higher the result, the "faster" or "better" the RAM.

For example, let's compare a first RAM with a speed of 3333MHz and a C15 latency, and another with 3400 MHz speed and C16 latency.

3333 / 15 = 222

3400 / 16 = 212

222 being the higher result, the first model of RAM (3333MHz /C15) is the best choice in almost all situations. Will you see a difference? Likely not most of the time.

Well done post on ram chrisax.

There one addtional factor as Stoks use a Ryzen CPU which sensitive to ram speed.

Ryzen has lane that connector multiple CPU core cluster on there chips this is called the Infinity Fabric.

The infinity Fabric has 2 mode 1:1 and 1:2. There mode tied to your memeory so 1600mhz (techainly 3200mhz since ddr id double data rate) memory clock would run infinity fabric at 1600mhz in 1:1 mode. 1:2 mode decouple the infinity fabric but adds a fixed 10ns delay basically negetaging any improvement that decouple to use higher memory would gain. So golden rule always best run 1:1

I mention all above as the fasest the infinity fabric the faster the overall performance of chip and memory. On 2nd gen ryzen 3000 seriries the sort cap of what average CPU will do on infinity fabric is 1800mhz.

So to get you infinity fabric running 1800mhz and be in 1:1 mode you need 3600mhz ram.

Just though make aware of extra sensetivity that ryzen has.

It is worth noting there considered 2 sweet spots 3200mhz which runs IF at 1600mhz ( this consider the budget midned opition) or max performance opition of 3600mhz ( it is about 2-3% faster then 3200mhz but demishing return start at 3200mhz)

So in short 3200mhz is fine. however Do make sur eyou turn XMP and actually run at 3200mhz as any speed below that sharply effects ryzen perfromance for example standards 2666mhz dd4 can lower FPS in game particular by about 15%.

This something well documented and unique to ryzen.

If stick similiar timings and brand then it shouldnt matter so much though as one videos point out once go 4 stick ram can get very fussy.

I would recmmond the following

So you have this MB (or a similar version):
https://www.gigabyte.com/Motherboard/X5 ... -rev-10#kf

This board has 4 RAM slots.

You are using 2 slots now, 2x16GB.


So you can add 2x16GB, for a total of 64GB (old+new).

You can add exactly the model you already have, as it's still available.

BUT the two vendors I see on the page of on Amazon Spain have insane prices; 388 euros for the cheaper one. :(

Fortunately, you also have other choices in Spain for the same model in white (doesn't matter) CMW32GX4M2E3200C16W :


On Amazon Spain

https://www.amazon.es/CORSAIR-Vengeance ... 871&sr=8-8

At 250.59 euros only.

On Corsair's own site in Spain

https://www.corsair.com/es/es/Categor%C ... 2E3200C16W
At 244.99 euros

What Buster posted

It's also the same model and at a comparable price


It seems that should work fine with your MB.

So all good, 2 more 16GB of that model, 3200 and C16, and you should be fine.
