Help to decide - 3200 CL16 / 3600 CL16?

[The King]

On Zen 3 3600 CL16 Dual rank 16GBx2 should noticeable outperform 3600 CL14 8GBx2 Single rank dimms unless you run a 8GBx4.

In regards to gaming performance.

how is DS supposed to improve with Dual Channel on ryzen?
im getting 53,5 GB/s read, havent seen much higher except on quad channel.

 

[The King]

unless board is quad channel, how is DS supposed to improve with 2 sticks?

Hi,
@Fry178
If you or anyone can get by with 16gb total memory good, you can always add another 2x8gb kit and take your chances but saying it's a waste is just fos

Most people buy trucks "In Texas it's our Cadillac" to haul things or throw a camper on it for outings/... it's cheaper than hiring someone or renting one when you need to do something simple as moving/.... or weekend/ vacation outing not a good example you tried to make.

The cost of c14 is only more dimm voltage bottom line

@The King
im not running 3200C14 he tested, mine is 3600C14, little difference.

@ThrashZone
its a good example, as its only single country, representing only 5% of the planets population, that does that.

@AusWolf
yes, or i hadnt switched.
about 10% higher transfer rate on avg, going from C16 kit i used before, latency around 54-55.
but then again, i use 3 Ms and a 2080S under water, so impact is more noticeable..

Transfer rate... latency... those are not applications. The difference that you feel and the difference that you measure are totally different things.

Personally, I couldn't even tell the difference between single and dual channel without an FPS counter on screen.

Hi,
3600c14 is just a higher bin of the same chips but this even depends on it xmp dimm voltage if more than 1.35 to do 3600c14 it's not a higher bin just another line of the same bins.

@AusWolf
everything you do goes thru ram, so yes, transfer rate is relevant,
or you wouldnt have HEDT using quad channel.
latency is relevant (on amd), and so far, anyone that i had trying 3200C18 vs 3600C14, could tell the difference (for the games relevant to us).

@ThrashZone
i know, just wanted to have the option to run C14 right away, until i got timings tweaked to what goes.
and i got A0, seems to like lower timings (without more voltage needed).

Is not so much about the CL more about the Zen 3 architecture.

It prefers 4X single rank 8GB dimms or 16GBx2 Dual ranks dimms.

If you add another 8GBx2 dimms your latency may go up but your gaming fps will increase more than going from 3600 CL16 to 3600 CL14

I'm not saying that there's no difference - I'm saying that the difference doesn't matter in everyday scenarios. The reason why people say it does matter is due to obsession with the maximum 5%. Nothing else.

Hi,
Easy as in using xmp profile
AMD is finicky about memory for sure thankfully 5k series was a needed improvement in this area if 5950x wasn't so overpriced at release or even months after I'd have one.

 

[Waldorf]

@The King
dont need more fps, not with 5800x and 2080S @2.1ghz

@AusWolf
not interested in fps, only latency/system response.
i do run OS/games at 2160p, so not saying this will be noticeable (as much), when using 2k or 1k res.

I'm not sure I follow. I'm using 3200 MHz CL16 RAM, and my system seems pretty responsive to me.

 

[Yearofthegoat]

The 'trouble' with Ryzen is the link between the RAM and the processor. My R53600 and my R95900X both boost / clock higher with 3600 RAM than with 3200. With the FCLK==UCLK and same CPU settings otherwise. So faster RAM gives you a double benefit.

Whether that ends up being noticeable depends on the individual and what they're doing with the machine, of course.

@Bones
according to what?
ignoring that the highly recommended gskill kit i bought, didnt even post (was on QVL), didnt tweak,
all 7 corsair kits i used in builds (half of em not even on qvl; incl my LPX) worked as expected, right out of the box,
4 kits doing lower cl at same V, my lpx kit runs 14-14-14-28-42/1T (havent gotten time to try lower).

unless you have +5000 customers with same issues, sample size is too small to be statistically relevant or making statements like yours.

My personal experience from years of doing computers as a hobby and as a competitive OC'er with others I know (Overclockers) that remove heatspreaders out of habit to check their IC's to know if it's a decent or better set to OC or not...... And they do mention things like this whenever they run into it.

And it's also the fact it's based on the same experience you just referred to for yourself in Italic as quoted.

That's what.

So you've had a good experience.... That's actually great but doesn't mean everyone will have the same everytime as you.

Whether it's something that's only encountered on occasion or even rarely, the fact it has happened does bear mentioning.
Making people aware of it isn't something bad to do because it's real and anyone of us, and I mean anyone can be the "One" that gets a set with different IC's in them vs another set of the same stuff and have problems because of it.

I've said what I've said and I stand by it all.

So there is no need to repeat or keep repeating myself here.
With respect to this....
Done~

 

[Yearofthegoat]

Depends - They could work well together or piss all over your expectations because it's largely going to be a matter of what IC's are in the sticks and if they are compatable with each other.
This is also why it's not a great idea to mix-n-match sets, some IC's really don't like being in the same system others may be in, it's all hit or miss when you try things that way.

If the Corsairs you have are working fine another set of those would be what to go for..... However Corsair is also infamous for changing what IC's in a model line, even if it's the same thing by it's specs and all else.
Even versions of the same thing (Such as Corsair Pro PC3200 2-2-2-5 v1.2 as an example) by name and model/spec between sets could be shown as being the same but could also have different IC's under the heatspreaders and that has been seen before from Corsair.

I've bought Corsair RAM since, well, as far back as I can remember - certainly TwinX days, possibly even before DDR2 was a thing. Reason for that was reputation at the time, and a 'lifetime' warranty. I haven't looked yet what the warranty policies are for the likes of Patriot, G-Skill or Crucial. In fact, the only time I had to return RAM was three returns of Crucial Ballistix (years ago, some bright orange CL4 DDR2 things - BL12864AA804.8FE5 according to the wrapper. Yes I'm a hoarder).

Since then I've had no issues with Corsair RAM, apart from the M2Z3200C16s initially not working under A-XMP. But I was expecting to have to dial in the RAM settings - it was like that before A-XMP/DOCP/XMP anyway. Right now those sticks are running happily at 3600C16 with slighly looser timings, but stable as far as I can test (HCI MemTest >1500%, Memtest86 boot disk no errors) so I'm happy enough.

You're right about the changing of the ICs of course. I looked online earlier to see what ICs people had in their 3600C16 and 3600C18 sticks, and it varies between Hynix AFR, CJR, Samsung non-B, and Nanya - going by review comments and images people have posted.

If I want to get more RAM it seems like there's no guarantee that their ICs will match any more than another brand's sticks would, so I'll look at those next.

 

[Bones]

That's exactly what was saying earlier, I don't know or can't say why they would do that but they did and it's proven fact.

I also know they aren't the only ones but out of all Corsair seems the worst of the lot about it. Not saying their sticks are bad, I have a few sets that's actually quite good but the fact remains they would start making sticks with a different IC within the same model line and sometimes even sticks with the same version when compared will have different IC's in them.

Stay on topic.
Quit the bickering.
Stop the insults.
If you have nothing to contribute in regard to the topic... don't post.

If you are going to get new RAM the website b-die finder is useful. Samsung b-die appears to work well compatibility wise and has good performance. Also make sure the motherboard plays well with the new RAM, the motherboards memory QVL and the memory manufactures QVL can help.

If you are going to get 4xDIMMs, getting a quad channel kit will help guarantee they work together. Normally two dual channel kits will work but people have stated the IC's can change. Just make sure the motherboard supports 4 dimms for the memory you do get which should be fine if you get Samsung b-die.
