How the hell do you decide what RAM to get anymore?

[Viper187]

Why is RAM the only thing advertised based on overclocking? I'm looking at this new AM4 socket stuff. The motherboards are spec'd at 2667, but the goddamn Ryzen CPUs supposedly support 3600. Why would the motherboards not support that without going through a bunch of OC settings then? If you buy the stupid fast RAM, do you at least get better timings/latency if you leave it run at the motherboard spec, or what? Is it worth buying faster stuff to "future proof" a little bit or just buy whatever meets specs and use it until the next new thing comes out?

seems anymore what ever offers the most hype and gimmicks ?? quality and support means little toady . [opinion] heck led lighting is now a strong selling point ? go figure

I just stick with what the CPU memory controller is rated for and all's all ways worked out fine when you use that overclock stuff like any overclocking nothing is guaranteed and at your own risk of it doing so ..

if amd says there cpu memory controller is rated at stock out of the box no overclocking for 3600 they should hold to it ?

my old joke saying is ''if its AMD its 1333 ''

you are overcomplicating things, to be honest i dont see any point in overclocking ram,the speeds we have now are more than enough for what we need,at least at consumer level, first,decide the CPU,see what RAM speeds are supported,then search for a suitable motherboard for you, then check what RAM speeds are supported for that motherboard, then from that you can pick whatever speed you want to go with(as long as both the CPU and MOBO support said speed), also you can never future proof a PC in anyway, what you get tommorrow could be outdated by the time Monday rolls around so you just go with whatever will suit you best at that time and forget about the near future.

My thoughts are that because the whole 'Ryzen' thing is still at a very beginning stage, that haven't released all the motherboards yet, so I'm sure that it will be soon that better and more powerful motherboards will be released for purchase. RAM speeds really don't have a huge effect on things, unless you are overclocking pretty much everything. Mainly with the CPU, because it can take advantage of the higher RAM clocks. The new CPU's do support up to 3600 MHz, and that's exactly why companies such as ASUS, MSI, Gigabyte, and many others will take advantage of this and produce more motherboards that support this higher RAM frequency.

Hope this helps clear this up,

With ddr4 ram, 1.2v is the stock voltage. That will be ok for ram up to 2400 speed.

Ram faster than 2400 speed is really 1233 ram of sufficient quality that it can be overclocked by applying more voltage.
A motherboard must be capable of adding that voltage. This is usually done by implementing xmp profiles imbedded in the ram.

Faster ram is accompanied by higher latencies which negate most of the increase in speed.
Real app performance or fps is not much impacted by ram speed. Possibly ryzen changes this.
Here is a report on skylake ram scaling:

My take is that more ram trumps faster ram.
Stick with 1.2v ddr4 and low profile ram.

Try dividing the cas into the speed to get a figure of merit on deciding which ram performs better.

I don't see any specs on it ?? like intel and say haswell intel rates there memory controller to 1600 , but you see ''boards'' supporting higher but a s far as Intel is concerned it 1600 is what they speced the CPU's for ?/

so there you are back in to that overclocking of the memory controller weather by XMP settings or manually set -- motherboards can run what ever there designed to run but that's also got to work hand in hand with the CPU 3200 may work fine with a few bios bumps then it may not get that at all and you finding anything stable under that at best

http://wccftech.com/amd-ryzen-cpus-support-ddr4-memory-speeds-3600mhz/

see? So why don't all the boards support that speed out of the box?

 

[junkeymonkey]

depends on the motherboards design from there manufacture ? that's like saying why don't a intel h board overclock or have NVidia sli capabilities

thing is just get the board with the memory support you want then hope the CPU you use will do it for all we know the amd Ryzen cpu's memory controller may not be even rated for native 3200 speeds anyway and why in the boards specs it called @OC cause you have to overclock it over the CPU's rated specs

look here

Memory Types DDR3-1333/1600, DDR3L-1333/1600 @ 1.5V

https://ark.intel.com/products/75048/Intel-Core-i5-4670K-Processor-6M-Cache-up-to-3_80-GHz

then notice all the boards for that chip the memory rated over that 1600 set by intel is considered at ''overclock ''

Memory StandardDDR3 3200*(*O.C.)/ 3100*/ 3000*/ 2933*/ 2800*/ 2666*/ 2600*/ 2400*/ 2250*/ 2200*/ 2133*/ 2000*/ 1866*/ 1600/ 1333

https://www.newegg.com/Product/Product.aspx?Item=N82E16813132287

this one claims 3300 on the same z97 series

DDR3 3300*(*OC)/ 3200*/ 3100*/ 3000*/ 2800*/ 2666*/ 2600*/ 2400*/ 2200*/ 2133*/ 2000*/ 1866*/ 1600/ 1333/ 1066

https://www.newegg.com/Product/Product.aspx?Item=9SIABVR4TX0350

see now don't support memory over 1600 [don't allow any overclocking so its the intel ''CPU'' rated for the chips memory controller

Memory StandardDDR3/DDR3L 1600/ 1333/ 1066

https://www.newegg.com/Product/Product.aspx?Item=N82E16813157511

thing of it is AMD 's memory controllers were not ''strong'' to start with and why I make that joke saying I used above ''if its AMD its 1333 ''


good luck on what you decide and all ways review the boards memory support list and any foot notes that come with it
