My ram speed
I have overclocked my ram to 3200 in the bios

I am using 2x 8gb sticks in dual channel mode

cpuz says my ram is running at 1599.1mhz
2x this number is 3200mhz

does this mean i have successfully overclocked it to 3200mhz?

dual channel and clock speeds have nothing to do with each other

dual channel just means that it talks to both dimms at the same time


the imc is the memory controller on the cpu

to run ram faster than its rated is overclocked

Dualchannel mode always runs the moduals a certian way. I have DDR4-2400 and it's clock frequency is 1200MHz per channel. It's normal.
Once again, that 1200Mhz has NOTHING to do with your RAM running in dual channel.
You are missing the point mate. The OP asked if his DDR4 Dual channel RAM would run at 3200MHz. The answer is no because of how dualchannle works. I used my RAM as an example.

You are clearly unwilling or incapable of understanding how this works..

Sicne you're so pro I want to make a simple test with you. Uninstall 3 RAM modules that you only have 1 RAM module in your PC. That way you can only use single channel. Then post a picture of your CPU-Z reading and your Bios reading. You'll see that CPU-Z still reports 1200MHz and the Bios 2400MHz which should be impossible to you .... then you will have an easy prove that you talk BS.

bios often gives the ddr speed instead of the freq to make it easier to see what the ram is effectively running at

cpuz shows the actual mhz and tells you its ddr

if you have 1 dimm intalled it can run at its rated speed
with 2 dimms they can run at their rated speed with dual channel enabled

Never said they do. The naming coventions is double the clock frequency of the RAM is what I am trying to say.

Note DDR4-2400 RAM running at 1200MHz

So if the OP OC'ed his modules to 3200MHz, that means the naming convention of the RAM in use would technically become DDR4-6400, which does not exist.

yes, but that 2666 (1333mhz) dimm will not run at 3200 (1600mhz)

if you check the memory tab it will show you its current speed/mhz and timings

Dual Channel: the RAM has 2 "memory channels" usable to them. Think of it like 2-lane highway instead of 1 lane.

Clockspeed: The signal has rising and falling edges. It's like a wave. First it rises then falls. Double Data Rate RAM can move data on both of these modes. 1200Mhz on DDR means it has an total effective speed of 2400Mhz.

not true aswell. the IMC can talk to all RAM modules at the samne time always. It not only able to do this in dual channel. Dual channel doubles the bandwidth by adding another lane.

The IMC stands for Integrated Memory Controller whiczh is on modern plattforms in the CPU (befor it was on the motherboard).
Anythign running outside of JEDEC specifications is an overclock however running on CPU supported speeds or XMP/AMP is questionable if it still counts as an overclock as it is simlair to a factory Overclock.

That you dont need to OC the IMC (which you still dont do) but it is soley depending on the RAM itself can be also easily tested and prooven. Taken a Ryzen 2600X and insert an standard 2133MHz RAM module and try to run it simply at 2933MHz which will mostlikely fail. If you isnert a Samsung B-Die RAM it is no issue. So it cant be CPU (IMC) bound.

your talking about bandwidth

adding a lane (going from singel to dual ch) increases bandwidth not mhz or making it ddr


traffic is a good way to put it

dual ch is 2 lanes, mhz is the speed of the cars, cl is the distance between cars
tri ch was the oddball with 3 lanes, since pcs use units of 2, a dumy car was sent with every car pair
quad ch is 4 lanes

if you scroll up to my other post, amd and intel list the rated speed of the imc in ram ddr4 2666/2933

You're mixing up the way and what is showing the speed.
The speeds in BIOS: shows already doubled speeds. CHoosing 3200Mhz there means it's 1600Mhz base and thus 3200Mhz effective speed.

Speed in the CPU-Z: the base clock of current speed.

And Dual Channel of course doesn't affect any of this.

Just means it runs simultaneously is all. I know. And Yeah my word use was a bit mixed up there xD

nope. I prefer the term bus but we can go with car to. Tripple channel adsds not a dummy car. it actually ads a true lane itself. It exist on Nethalem why they had 3x2 RAM slots. SklakeX Xeon for examply has 6 channel... same as we have six xore CPU's. In computer hardware you not doubleing everything....

CL is not the distance between cars. Imagine the Car need to transport people from A-B, then CL would be the ammount of tours from A-B the car needs to make to transport a certain ammoutn of people.
Thats why a faster car (faster RAM) does not help if you need mroe tours to transport the same ammoutn fo ppl. Thats why RAM speed at a certain speed does nto actually improve your systems speed because of the CL timigns it comes with (despite infinity fabric improvement).

Just ebcause you edited your post it not allow you to talk out of this.

Dualchannel mode always runs the moduals a certian way. I have DDR4-2400 and it's clock frequency is 1200MHz per channel. It's normal.

you multiple times mentioned your RAm speed and that it is because of dual channel. there is no way of mixing up your words a bit. You specifically believed that Dual channel would double RAM speed.

Same when you talk about DDR4-3200MHz would be effcitivly 6400MHz. YOu have no clue what you talk about it... standard JEDEC RAM is DDR4-2133MHz CL15. So accordign to you the standrad RAM should have an effective speed of 4266MHz.... and that would be the slowest DDR4 RAM on earth. We all know it is BS.
DDR3-3200MHz is already doubled effective speed of 1600MHz. as DDR4-2133 actual speed is 1067MHz.

tri adds the lane but a dummy car with each set of cars
effectively no faster than dual channel, but with 3 dimms
still faster than single ch with 3 dimms

packets are sent 1-2-x, x-2-3, 1-x-3 (x = dummy packet, 6 packets takes 3 waves)
