difference between dual rank and single rank? and more questions

[LOST TALE]

Will both run alone and together?

Will single rank run in dual mode with a dual rank?

 

is it worth paying 33$ to go from cas 16 to cas 15?

I'm upgrading my cpu.

While waiting for someone to rpely on selling his i7 4790k at 178$ CAD

 

Will overclocking a ryzen 2600 yield on average 9.25% more performance? because the cheapest mobo is 50$, and this one with 4 ram slots is 75$. getting the 75$ mobo instead would increase cpu+mobo cost by 9.25% . I think the answer is yes.

75

it's worth if it fits your budget. Ryzen loves good memory.

going for 3000mhz or 3200mhz memory will achieve this

But It's not an apu, are you sure? I have 8gb vram

 

I only focus on cas latency because of that video where linus shows that only cas mattered with ddr3. then I see ddr4 has even slower cas, so I extrapolate.

[Derrk]

ddr4 has slower cas because it has higher clockspeeds. It's a tradeoff but ryzen performs best with fast memory. Fast cl and high frequency is best, but also expensive

do you have a test demonstration? I wasn't able to find one such for bf1

Single rank is single sided and dual rank is double sided. Dual rank having more RAM chips on it makes it run hotter and gives you less chance of hitting higher speeds.

If I have the average decently ventilated case will it be fine? I mean I doubt they would throttle or overheat or can they?

 

Does it affect if they fit next to one another?

And paying for the lower latency may not be worth $33, but same speed with lower latency generally means better binned RAM so you can consider it $33 more for lower latency and greater potential for overclocking.

Only get dual rank (16GB sticks) if you need to fit as much RAM in your system as possible. Dual rank will run hotter. If you want to maximize your RAM speeds then always go single rank (8GB sticks).

This appears to be a dual rank 8GB stick

 

What matters more for frequency? buying a stick that is rated at a higher one or buying  one that is single instead of dual rank?

At those speeds none of it matters. 

 

 

The 2400MHzCL16 kit will do what that 2133MHz will do. The specs of that 2133MHz kit are running at JEDEC standards and you can safely assume all DDR4 RAM will do that.

@LOST TALE Are you looking for RAM to overclock or are you going to run at the advertised speeds?

I'm looking for ram to provide a good performance/$

 

Is any motherboard capable of overclocking ram?

That's difficult to answer. I would say to look at 3200MHz RAM if you're looking for the sweet spot for price to performance, but I don't know your budget.

 

And almost any motherboard you can purchase I imagine is "capable" in the sense that you can change the RAM speed in BIOS, but their actual capabilities will vary and sometimes greatly. I can't speak to how each board performs.

seems liek I should go with the 2400 besides it has a heat spreader

My only concern with using that video as a reference is no mention of the RAM timings. 

 

And if you're happy with 2400MHz then I'm happy.
