Ryzen r5 1500x with one stick of memory?

[chexor]

Will r5 1500x run fine on b350 motherboard, but with one stick of ram 8gb (2666mhz corsair), right now i have only budget for single stick because they are so expensive here.. Later i will add another same stick of ram, will it be oke?

[Jurrunio]

1 stick of ram is fine, but make sure you get the same model for the added one.

Try getting 3000MHz or 3200MHz. 2666 will run fine, but the performance gain of 3000/3200 is greater

Well they only have only patriot ddr4 3000mhz cheap, but they are 4x2gb sticks.

I want to get CORSAIR 8GB Vengeance LPX DDR4 2666MHz CL16 CMK8GX4M1A2666C16, will it work fine on b350?

2x4GB is better than 1x8GB, expect a significant performance hit if you only use a single stick.

It'll be single-channel instead of dual-channel. I wouldn't.

 

Also, memory is expensive everywhere.

Oke, but can i add later another same type of memory again 2x4gb (to be 16gb of ram?)

Yes, 4x4GB is a valid configuration (no added benefits, but no negative impact either to my knowledge).

I ordered: 

AMD Ryzen 5 1500X

MSI B350 PC Mate

CORSAIR 8GB Vengeance LPX DDR4 2666MHz (2x4gb)

Last time I checked ryzen memory clocks higher when only two dimms are occupied.

This.. Everyone keeps saying that but to be honest I've never seen any actual major differences except for in some benchmarks.. There's hardly any difference... 

The gains of faster ram in ryzen are obvious.. But I am still not sure about dual channel vs single channel

Can you give me actual data to support that.. I know that theoretically it should be faster.. But the difference tbh is not that evident 3~4% at best.. I suggest OP shouldn't spend extra for that.. If he is gonna spend extra it should be on faster ram

[Manu Saraswat]

As you can see here that under actual load there is almost no difference.. Notice how the frames when the games are on high settings the difference is almost non existent..

[Majestic]

That video is 3 years old. Back then memory speed also didn't matter. Now games have a lot more datastreaming and bandwidth usage.

Dual channel doubles your memory bandwidth, you will notice it. Especially in the low's.

OK.. Nd as you can see that when under actual load.. Which are realistic situations.., the difference is non existent.. See for yourself that when games run at high settings there is no performance difference.. In any game b/w a single channel and dual channel memory, especially with the faster rams

Logical fallacy[edit]

Moving the goalposts, similar to "shifting sands" and also known as raising the bar, is an informal fallacy in which evidence presented in response to a specific claim is dismissed and some other (often greater) evidence is demanded. That is, after an attempt has been made to score a goal, the goalposts are moved to exclude the attempt.^[3] The problem with changing the rules of the game is that the meaning of the end result is changed, too.^[4]

[Manu Saraswat]

Or maybe you could chalk it up to bad optimization.. The games theoretically should run better with more cores but they don't..dual channel should be better.. But the games don't show much difference.. It might very well be just the fault of games not being optimized to use hardware properly

It all depends on the GPU, in his case the GPU was the bottleneck in the 1080p tests where as it wasn't in the 720p tests meaning if he had a better GPU the RAM would have made an impact. The 720p testing shows that when the GPU isn't constrained, the FPS is significantly impacted (up to 30% in some games) by whether he had 1 or 2 sticks of RAM at both 2133MHz and 3200MHz. So yeah, if you're running a lower end GPU then you won't notice a difference, but the difference is definitely there when you remove the GPU from the equation.

Is incoherent and fictitious rambling your M.O?

LOL no.. I really do want to get to the bottom of this.. I do understand your point but all I am saying is that under realistic circumstances ram is rarely the bottleneck.. Your gpu nd cpu will almost always choke out before ram, which was evident in the video 

[chexor]

Well i got 2x4gb sticks, because i need to save up for Vega right now, and dont want to rush for another stick of 8gb (8gb corsair in my country is around 100$), so thanks both of you..

So we can all agree that there is a significant difference between single and dual channel RAM? It just depends on where the actual bottleneck is and the software.

Yeah.. I already said that I am not saying dual channel is not better.. All I was saying is that the difference are rarely evident in normal circumstances.. 

PS. My rational was also coherent to OP since rn he has a rx 570 which isn't any different to rx 470 used in that video 

But since he is planning to buy Vega.. I guess then dual channel may prove effective
