Memory Speed Suggestions for Ryzen 3700x - 3200 or 3600

[BrokenArrow]

Hi,

 

So I am building a new system, 3700x, with 570 chipsets.

 

I have decided to buy 32GB Memory, I need help to decide on two options.

 

1. 3200mhz - CL16 - 125 EUR

2. 3600mhz - CL16 - 180 EUR

 

Other higher speed options have a very high price, And that is out of my budget :(.

 

Which option should I go for? does How much improvement a 3600mhz can give in DCS?

 

Other system specs, 2080Ti, M.2, 4k 60fps monitor.

S!

 

Difference between those is not big, but if you can, then take the 3600MHz memory. I use 3733MHz CL17.

Thank You for the reply,

 

If I am not asking too much, :) can you please downclock your memory to 3200mhz and can check for any rough fps differences?

[Flanker35M]

S!

 

I doubt I will see any difference without using a FPS counter. I used 3200MHz CL14 memory on my Ryzen 2700X and never had issues.

Check the YT channel by Buildzoid called "Actual Hardcore Overclocking". There are spreadsheets in the videos that show you what the difference is, it's latency. I guess it's around 3-5ns difference, like 64ns vs. 68ns or similar. Good latency for AMD is below 70ns, bad latency is over 75 towards 80 or worse.

 

It may pay a small dividend when you fly VR but it will be small, tho I would try to get the 3600 CL16 and oc it down to 3600 CL 14, that is about as good as you can get.

Ryzen likes fast ram I'd go with the 3600. Just make sure the sticks play nice with your board or at least have a bios update that allows for it to. Check the mobos recommended mem. list.

Thank you for the reply, And Nice detailed youtube channel. :thumbup:

 

I have reached conflict reading your comment.

 

Considering 60fps means 16ms frame delay, in that delay, 80ns is almost negligible, right? like instead of 16ms we get 16.000080ms. That does not seem to worth 50 EUR for me.

 

Or am I missing some points?

I dont think there is a big difference, maybe 2-4max fps, is my personal guess. As long as the timings are not too bad a 3200 is still great. I have to run my 3600CL16 at 3000 or my board goes nuts with 4 modules and I dont have a negative side effect, but it's Intel. The only good thing, I get them down to CL14-14-14-34 at 3000 so I could minimize the negative impact.

What counts is your latency, which you can measure with Aida64 for example

 

I personally would go with the 3600 CL16 and tune it further down to like 3600CL14-14-14-34 if possible, maybe needs a lil higher voltage but a good Samsung B-Die could possibly do it.

For me, that was worth 50 bucks. Look at it as an insurance. Maybe not the best decision if you then lack 50$ somewhere else, then better take the 3200 kit.

 

To your math:

If you want and need 16ms Frametime you need 16.000ms. Having 16.080 would be a miss and cause stutter. Either it hits it ON THE SPOT ( VSYNC,GSYNC etc. ) or it's a miss. When the door is closed, it's closed, no matter if you are 20ns late or 20 days, closed is closed, there is no mercy and no cheating in Frametime allowance.

3200 one I am looking for is Corsair Vengeance CMK32GX4M2B3200C16

3600 one I am looking for is G.Skill Trident Z Neo F4-3600C16D-32GTZNC

 

Based on expertise you have, can you suggest which one will be better for overclocking?

[BitMaster]

Both are great, I run Corsair Vengeance in this DCS rig and run Gskill in my sons game rig, both 3600CL16-16-16-38-2t, both B-die.

 

I would buy the Gskill if neither one is in QVL...BUT check which of them is possibly in the QVL, get that one. Look at the motherboards download page for the QVL and study it, that saves some grey hair, that's the best advice in this case.

[BitMaster]

One thing to add from Buildzoid.

 

He said, if you buy 3000 or 3200 B-die you LIKELY get a lower end binning of b-die as they usually top out much higher and qualify for at least 3600 or better.

 

That is why I would not buy B-die based modules with 3000 or 3200 unless I had to.

 

B-die is not B-die, so to speak, they come binned, some are better and some are worse according to Buildzoid.

Okay, I have found F4-3600C16D-32GTZNC in QVL,

So I have decided to spend 50 more, Thank You for sharing all these info.

Wise move, you won't regret it :thumbup:

BTW, those are SK Hynix, not B-die, but that's ok as you shouldnt overclock them beyond 3600 anyways due to the 1:1 ratio.

 

...just checked the QVL myself :book:

 

**once the rig runs perfect, you can tinker with the 16-19-19-39 and see if you can lower those with up to 1.40 volts. If they run without BSOD its even greater :)

Sure, just placed order, I will add my findings here. Just wished DCS have a official benchmark option like other games.

Pretty sure that's what I got. Best bang for buck for more. Research I did suggested 3200 cl14 or 3600cl18 were about the same. Cl 18 on 3600 is a sweet spot for normal people without insane budgets. The cl16 was a nice bonus at no extra cost in my case.

 

I haven't played with timings other than set to 3600.
