Ram timings on x470 (free performance?)

Recommended Posts

Posted · Original PosterOP

So basically i have 2x16 ddr4 3600 cl18 ram.  The Asus X470 Prime Pro only goes up to 3466 speeds.  Would dialing back the speeds to 3466 and tightening the timings just be free performance?

From my experience on Zen platform (first gen) Frequency is more important than timings.  There is a math equation that determines this due to latency vs. Frequency but I saw very little (margin of error) change when focusing on timings, vs pushing 3600mhz which resulted in much higher frame rates and tighter frame times (gaming first, for me)

 

What CPU (give us full specs)

 

Likely to get stable, better timings, would be to increase voltage and drop it to CL16 and see if its stable (I wouldn't seek to first sacrifice frequency either way, Id try to get all the things - freq and timings)

the x470 mobo says it only supports up to 3466 so does 3600 actually give me any speed above 3466 on this mobo?

Yes.  That is the motherboards guaranteed will work with advertised speeds for the Memory Controller on the mobo.  Rest is just silicon lottery and voltage adjustments.

I have a 2700x but I will definitely upgrade in the near future

Then I'd try the XMP/DOCP profile.  Unless you mean that in BIOS the RAM speed only goes up to 3466MHz.  Which would then make me ask if you've updated your BIOS lately?

the mobo is an x470, the bios isnt holding it back, the chipset is

I'd imagine you can set DOCP in BIOS.  The chipset itself isn't a problem either.  You can run fast RAM on an X470 mobo.  My X470 will run 4400MHz like a champ with a 3900X.  The real question is whether the IMC on the CPU is gonna get 32GB of RAM running at 3600MHz and you won't know until you try.  

 

So are you saying that you've tried running it at 3600MHz or that the motherboard documentation only says it will support 3466MHz for your RAM configuration?

 

Also, did you install the sticks into the 2nd and 4th slots?
