AMD Ryzen: 4 vs. 2 Sticks of RAM on R5 5600X for Up to 10% Better Performance

Рет қаралды 1,338,830

Күн бұрын

This benchmark started as an AMD Ryzen 5000 memory timings and frequency benchmark (like of 3600 vs. 3200, 3800, with FCLK changes), but morphed into a 2x8GB vs. 4x8GB benchmark.

This didn't used to matter (much) on previous AMD platforms; in fact, running 2 sticks of RAM was sometimes better because it'd be easier to stabilize the tighter timings and higher frequencies than running 4 sticks of RAM. Now, with Zen 3 and the AMD Ryzen 9 5950X, R9 5900X, R7 5800X, and Ryzen 5 5600X, it's become clear that 2x8GB vs. 4x8GB can impact performance, although this may not carry to other capacities as you exit single-rank configurations. In this benchmarking we're looking at several kits of memory in the beginnings of a "best memory" performance round-up for Zen 3, but we broke it into an initial 2x vs. 4x stick test.

4xDIMMs single rank will be dual rank and that gives a performance boost sometimes, this is because the memory controller access them as dual rank memory on two channels. Basically the controller is dual channel but you can have single, dual and quad ranks. Ranks allow you to increase the amount of memory. Channels, dual channel means two command and data busses. A memory rank is a set of DRAM chips connected to the same chip select, which are therefore accessed simultaneously. In practice all DRAM chips share all of the other command and control signals, and only the chip select pins for each rank are separate (the data pins are shared across ranks). Modern memory devices are organized into ranks and each rank is divided into multiple banks, which can be accessed in parallel provided that no collisions occur on either buses. The two buses can be used in parallel: a request of one requestor can use the command bus while a request of another requestor uses the data bus. However, no more than one request can use the command bus (or data bus) at the same time. So each single ranked memory module can be connected as a single rank at each dimm slot. This means each rank has it own circuit. Say you have a Dual Rank memory module. You can only access one rank at a time because they both share the same circuit. When you select one rank, you cant select the second. Now with dual rank memory you can send commands to one rank and read data from the other rank. If they have their own circuits. In addition, modern systems can have multiple memory channels (i.e. multiple command and data bus). Each channel can be treated independently or they could be interleaved together. This means with 4xDIMMs single ranked. One channel can access one rank (first two slots) and the second can access the second rank (slot three and four). This means you can read form one rank and write to the other rank. Or read from both ranks at the same time. You cant do this if the first two slots have dual ranked ram. This is because both ranks share the same circuit. You can select only one rank at a time on the memory module. The chip select is the own difference on the PCB. The data circuit goes to both ranks on the RAM PCB. This implies to access one, you become locked out of the other. Many dual rank kits have poor timings, like CL16 and CL18. With a dual rank kit, there are normally chips on each size of the PCB (While most often the number of sides used to carry RAM chips corresponded to the number of ranks, sometimes they did not). So to get around the poor times of dual rank kits, you can run for example two single rank kits (4xDIMMs). So all of your 4 x DIMM slots are full. With my motherboard that means 3600MT/s dual Rank CL14 with decent b-die memory. This nets me near to ~800 point more in time spy cpu. I hit 15k approx. with a 10900k. My latency increases from 42ns single rank to 47ns dual rank as expected. This is with a CR of 2, so this would be better on a better motherboard than mine. I am no RAM expert but that what I got from A Composable Worst Case Latency Analysis for Multi-Rank DRAM Devices under Open Row Policy white paper. Zheng PeiWu - Rodolfo Pellizzoni - Danlu Guo

Hey GN. It's been a busy couple of months with several launches and you're work is excellent. I revisited this video and there clearly is a gain on 4 RAM sticks vs 2 however, reading into memory overclocking recently, I found out that it could also be a characteristic of the motherboard and it's memory trace layout/topology rather than. Exploring this subject would help clarify (although it is complex) the decision making for RAM sticks (frequency, latency, true first word latency & quantity of sticks) when people make their decisions in buying RAM to match their Zen3 chip/motherboard combinaison.

Buildzoid has a video (~ 4 weeks ago) that seems very related to this topic. This could to be from the difference in the memory rank, where 2 sticks is 1 rank per channel vs. 4 sticks being 2 ranks per channel. The memory controller can interleave the allocated memory which can allow 1 rank to be read while the other fetches some requested data. If this is the same as what you've observed, then I believe this is also present in zen 2. Not sure if intel also has this feature. Edit: this would also explain why Wendell suggests 2x16GB to be the sweet spot since most (all?) 16 GB memory sticks are just 2 ranks of memory on 1 stick and are essentially the same as 2x8GB as far as the memory controller is concerned (OC stability concerns aside).

Building and selling high performance servers we have seen this difference for several years. As dram chip sizes got larger, single rank dimm became more common and a memory channel with only one dram rank performs 10-20% worse than configs where there are two or more ranks on each channel. GN should see if they can find 2 dimm set of 16gb dimm a with two ranks on each dimm (16 or 18 chips on the pcb with 8 or 9 on each side) and see if they get the same performance as 4 sticks

The memory benchmarks are the same before and after the upgrade to 64 gb. This will limit the maximum clock speed but does not cause any problems. If anything, this is actually the best high density config for the Zen 2 series as it can be used at XMP without tweaks unlike the 3600 CL 16 b die requires as it puts too much load on the memory controller. I look forward to upgrading to the 5950x while carrying over the same ram as I'm very pleased with the performance of stock, always being amongst the top scores for my hardware (running at stock).

Hi Steve, I think you misspoke at the end and meant to say that 2x16GB dual rank dims are a little better than 4x8GB single rank dims. 2x16GB single rank dims (ex. Crucial Ballistic Max 2x16GB) are only 128-bit, so you are not getting the benefit of interleaving that way. I would also be interested in seeing how 4x16GB dual rank dims perform in your future video because there is a good chance 512-bit would overload the memory controller and tank your achievable memory frequencies. I'm curious if the additional bandwidth of 512-bit at slower speed would be enough to overcome the FCLK penalty compared to 256-bit and higher speed. I suspect not... TL;DW for everyone else... For best performance you want to have a memory set up with 256-bit bandwidth meaning 2x dual rank dims(2x128-bit) or 4x single rank dims(4x64-bit). 2x single rank (ex. 2x8GB) can leave up to 10% performance on the table due to lack of interleaving.

24:30 So you had the correct answer all along, but for some reason did a whole bunch of testing and presented it as some kind of mystery that's totally new with Zen 3. It isn't new at all. Zen 3 just shows bigger differences in some applications. Those G.SKILL TridentZ sticks have a single rank. Use two of them, and you get one rank per channel. Use four of them, and you get two ranks per channel. That in turn gets you rank interleaving, which increases performance, in basically the same way that using multiple channels gives you channel interleaving, which increases performance. All bog standard stuff with computer memory. Using two sticks of dual-rank memory will probably provide slightly better results, because it's only one DIMM per channel, but still two ranks per channel. More than two ranks per channel might allow a very slight increase in performance, but the achievable memory speed also goes down as the number of ranks per channel goes up, so the optimal choice is likely going to be higher clocks with just two ranks per channel.

Hi Steve. It's not the number of sticks that matters. It's the number of memory ranks per channel. Buildzoid has done a video on this called "Testing XMP settings in dual and single rank". Because of interleaving between the ranks the memory controller can talk to the 2nd rank, while the 1st one is "busy". This also has the effect that the more ranks you add per channel frequency starts to matter more and timings affect performace less. Sorry for my bad English.

I thought I had RAM nailed for my next build (will be done within a month) . Gaming is only a little important, I want to run DaVinci Resolve for editing and rendering 2k vids and later 4k vids. The plan was to start with 2 sticks of 32 GB each and then add 2 more later if needed. Looks to me like single ranked is totally out of the question for me. I just have to get Ryzen optimized RAM wherever I can get it, apparently, and not worry about this. Please don't tell me I don't need 32 GB for projects, I fill 16 GB just going overboard with Firefox tabs.........like when looking at the right side of KZfaq to pick stuff for later viewing.......for PC research.

"Games REALLY don't need it." Cities: Skylines would like a word. My savegames with mods was reaching 14gb used, which prompted me to upgrading my RAM to 32gb. I went with 4x8gb, which is why I'm watching this.

To be fair this is pretty much one of the only games that actually will blow through an entire 16GB.

I'd be curious to see how the RAM configuration would impact video editing and rendering.

After seeing this, I added a matching kit of GSkill Ripjaws V 3200mhz to my rig and saw the Mersene/ Prime95 iterations drop from 30ms to 17-18ms with my Ryzen 5 3600x at stock 3.8ghz. This knocked 8-9 days off my workload. haha GG Steve xD

Damn, now I'm happy that I bought a 2 kits of 2x8gb (by mistake), the 5000 series will be a worth while upgrade in the future (going from 2700x). Thanks Guys for the video ! Keep it up

I'm at work, so I can't watch the video with sound fully, but I've been researching more about the whole 2 sticks VS 4 with the 5900x since recently after stumbling on a video testing that and 4 sticks being only a bit better in certain instances.... And recently trying to build a PC for a friend and thinking of selling him my RAM to get 2 sticks for myself (would be discounted and he does video editing) and get those 2 sticks to have some RGB lighting. ..... And also reading more and more about how pretty much Threadripper boards can use quad channel and dual channels can have trouble with 4 sticks........ Yeah, it's not easy.
