Ryzen 1### Memory Scaling testing

[humbug]

There isn't much information around about how much extra performance you can get with faster Ram on Ryzen 1, so to satisfy my own curiosity i spent half an hour testing, the results were surprising.

Just one game, i may or may not add more later.

Grid 2: Maximum 1080P MSAA 0, GTX 1070.

Corsair Vengeance® LPX 16GB (2x8GB) DDR4 DRAM 3000MHz
CMK16GX4M2B3000C15

Ryzen 1600 @ 3.9Ghz

Other relevant settings:

DRam Volts 1.41v
SoC 1.11v
PROC OPT 48 Ohms

It seems timings make some but little difference, outright speed has about 55% scaling.

Other results from the net.

There are a couple of good videos from the guy at MindBlank Tech showing how well it scales with speed and timings

Pretty sure it works like this till 3200 then timings start being more important.

Shown pretty well here, gamers nexus: https://www.gamersnexus.net/hwrevie...m-overclock-windows-update-efi-updates/page-5

You got the ram to go higher? 3 weeks till I get to see where my b.die can go

This is an excellent example with clear graphs by os4321, thank you

I have an older graphics card (AMD R9 280X) and was curious what impact RAM speed would have.

My conclusions from basic Unigine Valley testing:

* In a GPU bottleneck Scenario (e.g. if GPU utilization is 99%) no noticeable FPS increase observed.
* RAM speed/timings help to address CPU bottleneck scenarios (similar to overclocking the CPU).
* About 8% FPS Avg performance increase going from bios default 2133 15-15-15-36 to 3200 14-14-14-34 in a CPU bottleneck scenario.

Quick observations (in a CPU bottleneck scenario):
* A 19% CPU overclock (3.2 to 3.8Ghz) --> 16% FPS Avg increase
* Ram overclocked to 3133 14-14-14-34 --> 7% FPS Avg increase
* CPU (3.8Ghz) + RAM (3133 14-14-14-34) --> 21% FPS Avg increase

Unfortunately i can't get it any higher.

Eh, I'll be sure to report back

Graphed it for you, as all that text was making my eyes hurt

That looks great, thank you

Nice little chart - thanks for doing the research.

 

[Sumanji]

Cool, thanks for running this!

Defo worth investing in 3200MHz+ RAM for Ryzen 2xxx then? Potentially even better gains if the memory controller is more optimised.

Yes probably, and apparently Ryzen 2### series will run memory upto 4000Mhz.

 

[Mercutio]

Grab 16GB of b.die unless you're doing serious work. You'll not regret it at all.

 

[Sumanji]

Yeah I don't think anything I do will require 32GB, so with the prices as they are now, guess it makes sense to get the fastest possible 16GB dual channel kit.

If it's CAS 14 @ 3200MHz, it basically has to be Sammy B-Die, right?

It also works fine with 32 GB's as well.

As you can see, B-die works fine at 3333 at fast speeds even when you have 4x16GB. They have done for ages in fact....................it's just all the "doubters" that have never run or owned Ryzen like to spike that old ram rubbish are listened to more often than peeps that actually run it.

Part of the reason I bought the bdie 3200 8 pack RAM was assuming the IMC on Ryzen would improve so I could assuming it performs well simply drop in the third version of Ryzen in without needing to upgrade anything and get better memory speeds.

 

[Scougar]

If the 2 serious brings better memory stability, I am sold. Love Ryzen, hate the memory training.

 

[yoyo59]

I thought I was the only one who loved Grid 2?

haven't played in a while but lvl 99

Grid 2 can be extremely fast paced once you get up the tiers glad to see high ram speeds matter

 

[rs155]

I had a 10% improvement when i clocked my ram from the 2400mhz up to 3200mhz. I am using 8pack dark pro team group stuff.

Forgot to add that is on a ryzan 1700

Love the grid series as well. I have so much scrap wood from my house projects now sitting in the basement, that I will be making a racing frame for my seat and pedals to start playing again.
