4 ram sticks in dual channel

Should I go 2 sticks of 32Gb or 4 sticks of 16Gb? Ryzen 9 3900 on a B450 Steel legend, if it matters...

You watching: 4 ram sticks in dual channel

Thanks!



I WILL discover your ITX develop thcheck out, and I WILL recommfinish the SIlverrock Sugo SG13B

 

Key PC:

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - Hyper 212 Black (through RGB Riing flair) - EVGA G2 650W - Black and also green design template, Razer brainwashed me.

Draws 400 watts under max fill, for recommendation.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

How many kind of watts perform I need? Seasonic Focus threview, Userbenchnote (Et al.) is trash described, PSU misconceptions, protections described, team reg is bad

You have made too many type of threads. You have the right to make a solitary thcheck out asking for a develop suggestion


Sorry, was just trying to break it dvery own so as not to get right into the weeds through unassociated stuff... Will do a "general build" short article if necessary.

4sticks is constantly much better because of even more spreading of cores per stick, its about 10% acquire on mem bandwidth ( and via ryzen fps also )

You don"t obtain any kind of memory bandwidth with 4 stick over 2 if it"s just a double channel motherboard, choose the Steel Legend pointed out in the original post

Ignore
Valkyrie Lenneth, he"s either trolling you or he doesn"t know what he"s talking around.

4 sticks is not always much better.

 

Unless we"re talking Threadripper or other extremely high finish Intel processors, majority of processors on the sector have actually a dual channel memory controller, wbelow each memory channel deserve to support a maximum of 2 memory sticks.

So, you obtain the many performance once you use at least one stick on each memory channel, so two memory sticks. If you install 4 memory sticks, you won"t obtain much better performance, it"s still just two memory networks moving data to the processor cores.

 

In fact, when you have actually 4 memory sticks set up, there"s double the amount of signals going in between the memory slots and the cpu socket which indicates there even more "noise" inside the circuit board and also the memory controller inside the cpu hregarding work harder to get the data and also correct any tiny errors that may happen.

Because of this, you might uncover that on cheaper motherboards, you might not have the ability to run 4 memory sticks at high frequencies favor 3200 Mhz, but the very very same memory sticks would run just fine at 3000 Mhz - at lower frequencies each little of information continues to be simply a tiny bit even more on the wires between cpu and also socket and the memory controller inside the processor has actually a bit even more time to decode these weak signals and detect correctly if it"s a zero or a one bit.

 

So you need to constantly install as many type of memory sticks as the amount of channels the memory controller inside the cpu has, or double the amount (yet double that amount will not provide you more performance).

For socket AM4, you have actually 2 memory networks. Threadripper has actually 4 memory channels, so you must install 4 sticks. 

There"s some Intel processors which have just 3 memory networks and also in the past, AMD had actually socket AM1 or FM1 if I remember appropriately which had just memory channel.
