3800mhz CL14 @ 1.5v vs 4400mhz CL19 @ 1.45v - which is better?

[spartacus216]

3800mhz CL14 @ 1.5v vs 4400mhz CL19 @ 1.45v

Which is better? These are standard XMP profiles on an Intel MB. Which would you recommend and why? The cost of these is similar.

[Haro]

I would say they are both comparable in performance

But since the 3800mhz kit runs at lower voltage and I would assume both of these are micron quality and above I would take the 3800mhz kit

Lower cas latency  and since it runs at a lower voltage it will have more headroom 

But both are comparable in performance 

Maybe the 4400 would out perform it by a slight bit

But a casual user won't notice the difference

[Jurrunio]

3800 C14 should be better for the XMP gang

The 3800mhz runs at a HIGHER voltage.

Ohhhh didn't see that my bad lmao

Still my answer is the same 

3800 kit

lol, no problem. Just curious, but what made you come to this conclusion? I know when you do the math, the latency IS in fact lower on the 3800mhz kit but does the 4400mhz speed make up for that enough if both are the same price and both on the QVL?

Well interms of performance they are almost identical

But the reason why I went with the 3800mhz kit is because it will be better for xmp like what @Jurrunio said 

And because imo latency contributes to performance more than the frequency 

Because at a certain point (on both amd and Intel ) the latency between the data getting from the ram to the ccx or multiple ccxs for amd gets to the point where it is good enough and the 3800mhz being on paper slower means that the imc will most likely handle it even on amd's side

Interesting. This is starting to make some sense. I have a 4400mhz kit in one of my other systems but it was hard to get it to 4400 no matter which XMP I used, however I could fine tune it and got it to work but stability was an issue, so hard to do in fact that I had to set it to 4000. I assume that the lower the mhz on the kit, the easier it is for XMP to work? Stability IS a big deal to me though I'm not obsessed with it haha.

Memory speed is only useful if the CPU needs it (otherwise it's left with nothing to transfer), but latency is always useful (as it starts the transfer earlier).

Wise thoughts. I never looked at it like that before. Thanks.

Well If your running ryzen 

Their imc is still meh 

And with an oc ( I assume you have an oc on your cpu of some sort ) the infinity fabric simply won't handle that 

And the imc won't handle 4400 

I have very rarely seen an imc on AMD that can get to that speed 

[nick name]

Assuming both kits are b-die they will achieve and perform the same at the same timings and speeds.  They just have different XMP profiles.  So what you're really trying to determine is which kit will do the best with least voltage and that would be trying to guess which kit is the better bin (if they are different bins at all).  I'd guess that lower voltage kit is the better binned.  This is only relevant if you want to overclock or manually tune your RAM.  

 

If you wanna run them at XMP then I'd go with the 3800CL14 kit.

Hmm then this is a little odd but non the less my answer remains the same 

Lower cas latency with slower frequency

[spartacus216]

@TofuHaroto Here's my other issue. This MB doesn't have a setting for 3800mhz. It has everything in between. Will that matter?

Do you mean on the listing of when settings an xmp profile ?

It only has 3733 and 3866?

 

Find the 100:133 ratio thing (whatever that's called) and change to 100:100

They are both b-die, yes. I usually manually tune everything for the most part but no competitive overclocking, just the usual stuff. I've been a tech since I was a kid actually but I have never really dove into these types of situations so I appreciate the help. Based on what you said though, even though one runs at 1.5v, couldn't I simply O.C. that same kit to 4400mhz @ cl19 or whatever and maybe it'll run at 1.4v instead? Obviously I would have to play with it some but I don't think you could just pick the RAM with the lowest voltage as the best honestly because there's a ton of 3200 kits at 1.35v and lower but they won't come close to what these can do.

Correct and it is 100:100. It is an Asus Maximus XII MB. They are all like this. It's an Intel board. I do not have the RAM in hand yet but I spoke to Asus and they said the 3800mhz doesn't exist in their BIOS, however I could select the XMP and it'll pick whatever is closest. I found that odd myself.

I recommend seeing for your self 

I have seen more odd frequencies than 3800mhz lmao 

It could work but I could wrong

That's silly, 100:100 cannot give xx33 or xx66 numbers.

 

In that case just select 3733MHz multiplier and raise BCLK till you get 3800. This may cause instability with CPU at stock settings so you need to stress test this to verify.

Yeah I have the MB on hand, just not the RAM since I'm trying to pick between two kits.  I'll link them: 3800mhz or the 4400mhz    

 

Maybe that will help to see the full details. Both are on the QVL.

That thermal take ram is also b die if I recall correctly but I have not seen any reviews on it
