RAM plus ryzen 2700x

alkatraz333.jh · May 25, 2018

This is my first time owning a ryzen chip, and ive been hearing a lot about needing to pair it with a specific kind of RAM. I dont know too much about RAM either when it comes to CL. I just know the basics such as Mhz.

The exact ram model im using. Money really isnt a limitation, and i really want to get the most out of my chip. I do have a strictly RGB build, so would like to stick with trident if possible. I know they have different models.

They will work but if you can get 3200mhz RAM I would suggest that, Ryzen at least first gen perform better with fast RAM and 3200 was the sweet spot. Id suggest using pcpartspicker.com to find the best deals on RAM, cause it can fluctuate heavily from site to site.

Would 3600hz be better? It has 17 CL though vs 16 on the 3200hz

3200 will be fine.

If you're getting an X470 motherboard to pair with that shiny new 2700X, get the fastest reasonably priced RAM you can. 3200 was the sweet spot on the X370, but there are still gains to have with the new Ryzens. Sure, most of it you won't really notice unless you're CPU crunching, but they're still there. I'd try to hit up 3600 - 3800 in that area, but keep a tight eye on the CL as well. Look into the memory chip manufacturer, for example, I have G.Skillz, but the memory chips in them are made by Samsung. As far as I know, Samsung "B" Die are the top of the line, usually you can tell simply by it being fast RAM and Same Same Same timings, for example. "B" Die will be 14-14-14-28, whereas still good but not as good RAM will be 14-17-17-34. In that naming scheme, the first number is the Cas Latency or CL and that's the main primary timing. Hope this helps. And remember, with memory, everything over 2133/2400 is overclocking and while it might be rated higher, it's not a guarantee, every chip and every motherboard are different, you might have to tweak, you might just have to set it and forget it. You won't know til you put it all together.

3200 is the sweet spot, as mentioned. That's set by AMD as most of the AM4 motherboards will only officially recognise upto that amount. Some of the 2nd Gen Pinnacle Ridge X470 mobo's will support upto 3600MHz (OC) but you'd probably also need a 2nd Gen Ryzen+ Pinnacle Ridge cpu for that, not the 1st Gen Ryzen Summit Ridge.

I mean, i dont need literally THE BEST of the best RAM. I dont need a 2500 CB score lol. I really just play games, and edit videos a shit ton. The gskill trident has a 16 18 18 38. Does it REALLY matter THAT much?

Thanks for the help

The CL 14/15 Trident-Z's at the time of Ryzen release, along with FlareX and Patriot Elite are all Samsung B-die and by far the most stable, and about the only ram that'd consistently hit the actual 3200. The CL 16 are Samsung C-die I believe and were a little more hit-miss, but still far above SkHynix and a little better than Crucial. That's all been remedied by bios microcode updates, but just on an off chance silicon lottery deal, SammyB are still the safest bet.

3200/16 is a hair slower than 3600/17
3200/15 is a hair faster than 3600/17
3200/14 is faster again.

Because of the timings, even though the 3600 processes faster, the lower Cas gets the info through faster, but you are talking about several nano-seconds difference, in the big scheme it's only a 1-2% difference, translated to games that's 1-2fps at 100fps output. Not really a deal breaker. 3200/14 vrs 3600/17 is closer to 5fps.

So, like with CPUs? Its just a gamble? Or are they unstable as in, all of them are like that? Because i could always return if its the lotto kind of thing and get another set. And how will i know if its a good one or not?

Cpu = silicon chip. RAM IC = silicon chip. So yes, there's always that factor in any of them, but that's only affected at OC levels. At stock levels, they are guaranteed to be stable. The problems with ram and Ryzen wasn't due to the ram, but to the infinity engine (AMD's new version of hyperthreading) vrs the rams controller chip. There were some incompatability between how the ram operated according to cpu usage. That's why gigabyte (they started the fixes) and amd and others jumped on the ball quick to get things sorted. Ram isn't just ram. Take an 8Gb stick. It'll have 8x IC's at 1Gb each and a tiny by comparison controller chip. It's basically the bios/cmos of the ram, where all the details are kept like size, speed etc but also organizes those 8x IC's to run as a single unit.

The memory controller in the original release Ryzens had issues talking to the rams controller, more so with SkHynix than Micron or Samsung. So Corsair Lpx took a beating, almost impossible early on to OC beyond stock, (that includes xmp profiles), Crucial was better, and SammyB the best.

Those issues are all but eliminated, shouldn't be any issues now, especially at the ryzen+ levels as all those fixes are now hard-coded, not add-ons.

Thanks a lot for the info! Appreciate it!

hey, i need to know, what does "ryzen+" mean? I'm thinking about getting a 2700X or an Intel cpu and this issue has been on my mind. if I get ram, is "ryzen+" a logo, or certification i need to look for on the RAM's spec sheet?
