Good Ram?

[Huibert]

Hi Guys!,

Im building a pc and im thinking what Ram to pick up.. Higher or Lower MHz
Maybe you have some better RAM to suggest.. Would be appreciated!

Thinking about the HyperXFury DDR4-2133 - 16GB

 

current PC build: https://gyazo.com/c178048cbb104bcc74fa374c20794cf3

[Mi26]

any frequency of ram will work just fine, get the right type

If I made a Z170 gaming rig I would grab DDR4-2400MHz or DDR4-2666MHz, I would only go for the 2133MHz if it was notably cheaper.

Assuming you'll be using a Z170 mobo (or X99, otherwise it literally makes zero difference), get a 3000mhz kit. They are only marginally more expensive than regular 2133mhz RAM while providing a small boost in gaming performance.

mhz dues not matter these days. they are all fast, however, there is a list of popular quality brands:

Adata

corsair

kingston

crucial

samsung

RAM clock speed doesn't make much if any difference in most things. If you're not sure, just get the cheapest kit.

[Huibert]

@WoodenMarker

HyperX vs the Vengeance..
Think im going for the 2400mhz because its like 2 euro's more for the HyperX en for the Vengeance 10 cents cheaper

Anything past 2800MHz wont give you notable gains so 2666MHz is probably best value?

[Joeteck]

Keep in mind, its all about the timings, not the frequency.

Yes lower CL = better!

I'd pick this one.

[Joeteck]

DDR4 @ 3200Mhz with 16-18-18-36 is slower than DDR4 @ 2400Mhz with 14-16-16-31.

 

EDIT: Personally I would go with 10-12-12-28 @ 2400Mhz, but that just me.

Nope. That 3200 ram is lower real time latency than that 2400 ram. From the higher clock, the 3200 would be equivalent in latency to 2400 at 12-13.5-13.5-27 plus you get all that lovely bandwidth on top.

 

If you want to push for lower latency and/or higher bandwidth depends on the application, but in general I find going for higher speeds will get a latency benefit for free and overall less likely to bottleneck the CPU.

I disagree. Timings win over frequency.  Whats the point of bandwidth if you're timings suck? You'll need the bandwidth to keep up. CL is the first timing that is key. 

 

 

OP: I would go with the lowest timing on what ever RAM you choose.

 

[Joeteck]

I'll make this real simple.

 

Take the first number of the timings and divide that by the frequency. lets use 11 for 2400Mhz and 15 for 3200Mhz. (You'll see why in a second.)

 

so lets take

11/2400 = .0045833333

15/3200 = .0046875000

 

Which one is faster?

 

Correct! the 2400Mhz ram.

 

Now lets compare apples to apples.

15/2400 = .0062500

15/3200 = .0046875

 

Obviously, the 3200Mhz ram. 

But there is no need to go that high when timings is truly key.

 

2133Mhz is the standard for DDR4. Meaning you're not in an OC state for RAM. Going 2400 will give you some OCing room if you have a locked multiplier on your CPU. If you do not plan on Overclocking.

 

10/2133 = .0046882325

15/3200 = .0046875000

 

See my point now?

All of those memory modules are what I recommend for people depending on their budget.

And why would you do that? What are you trying to calculate?

 

In any case, there is no reason to overlook frequency or timings, as both contribute to the effective speed. In order to know how both things combine, you need to do the appropriate calculation as explained here (no, it's not the troll channel):

 

There's a link to pre-calculated Frequency+timing calculations in the description.

 

OP, if you are not in a use case that requires the fastest possible RAM (and you would know if you were),given the options you listed, stay within €80 and go with the best timing and frequency combination (see table), warranty, and any superficial preference you may have (like color scheme or brand trust).

Those aren't the timings when I quote-replied to your earlier post, so is a different comparison.

 

I stand by what I said. If lower latency and/or higher bandwidth helps in a particular application, you need to work out and optimise as applicable. Low latency low clock ram might or might not give you a latency advantage, but it will give you a bandwidth disadvantage. Faster ram will naturally get some benefit to latency also.

 

I recently upgraded ram on a Xeon system from 2133 C15 to 2133 C13, since I can't overclock ram with the Xeon. I know from past experience, ram bandwidth helps a lot for the applications I run. So what difference did that latency make? Practically nothing. Worth a try anyway. I'd love to go dual rank on that system which will help a bit too, but it'll roughly double the ram cost as it only comes in bigger modules.

So the HyperX Savage 16GB DDR4 2400MHz 12 cas latentie are good right??  (€89.90)

[Huibert]

owh i think im going with the HyperX Savage 2666MHz 13 cas latentie! for €92,90

12cas and DDR4? That is very good! o3o

Great choice
