AMD Ryzen 3000 Builders Thread

[Hans Gruber]

Yeah, a friend of mine sent me that kit, on ebay, from "adata_usa" (presumably factory-direct), for $69.99 (*plus tax, if applicable). Not too shabby, really. Looked pretty neat as far as heatspreaders go too.

I think Newegg currently has the GSKill TridentZ RGB DDR4-3600 ("for AMD") model in a 16GB (2x8GB) kit for $89.99 (or maybe that was the 3200 kit?)

I have two of the latter kits in my rig with a Ryzen R5 3600 on an Asus B450-F ROG STRIX board. Interestingly, although the board is now listed on their site as "Ryzen 3000 Ready", detailed specs only list DRAM speeds up to 3466, not 3600. I'm running @ 3600 (XMP, with both kits, using "DOCP" setting in Asus BIOS), and 1800 FCLK to match.

Still, I have freezes about once every month or so, requiring hardware RESET button to be pushed. Not sure why, I really "push" my system, and I've got two fairly beefy GPUs (an RX 5700 and a GTX 1600ti Gaming X model), I do some mining in the background while web browsing and Skype.

Larry, I got $14 or 15 in ebay bucks from my Ryzen 3600 purchase. I applied those to this XPG memory kit. So I am in it for $62. It arrives on Tuesday. Because of the unusual stock timings 18-20-20, I found reviews for the Geil Evo II kit for Ryzen with the same timings. Those are Samsung sticks and anandtech says 3200mhz are C-die and 3600mhz sticks are D-die. There is also the tea, T-Force Xtreem 16GB 3600mhz kit. If you check newegg, people believe that since the kit is Samsung memory that somehow that means the memory is B-Die memory.



This is what I am shooting for with the XPG 3600mhz kit. 16-17-17-34 (1T)

My MSI B350 Gaming Pro Carbon literally runs anything I put in it. MSI did a good job with the AGESA 1.0.0.4 bios.

3600 at CL14 will be more expensive than CL16 so not sure I would call that a bargain.

I guess you missed my point.

The bargain is getting 3600 CL14 for the price of 3200 CL14. Currently the cheapest 3600 CL14 is $190 on newegg. The G.Skill 3200 CL14 is $120 currently which makes it a bargain if one's after 3600 CL14 as long as the sticks play nicely.

I didn't miss your point. Even at that price it's a ripoff. Paying almost double for Cas 14 latency. For 3-5% improvement on performance is a waste of money. Obviously if someone wants the very best performance. Money is no object.

Dunno how many times this will be posted on these forums, but if you are after a bargain on good RAM for Matisse:

Are you a human?

www.newegg.com

or

(the 32GB kit is $145)

It'll hit DDR4-3600 pretty reliably. Just use Ryzen Memory Calculator and off you go.

Is that the Rev. E Micron memory?

 

[DrMrLordX]

Is that the Rev. E Micron memory?

Yes, micron e-die. Look for "AES" near the end of the product code - usually AESC or AESCK.

What are the good timings for Rev. E memory @ 3600mhz?

I don't think so.

Hans is clearly concerned about the cost of price / performance and you are telling him to buy more expensive memory. And his follow up post clearly agree's with what I posted.

Usually around CAS 16. Ryzen Memory Calculator can give you the best information there. I think there will be a 16-18-16-38 timing set built into the DIMMs already, but you can do better than that.

At what point in the conversation did I tell him to run out and buy some Samsung b-die memory?

 

[Hans Gruber]

I think it was this point. It seems you were pushing for CL14 memory as a bargain at this point in the conversation.

For some reason, this post actually fits perfectly.

E die is best for really high clocks from what I've read and is lower prices per GB. B die is better for lower latencies at a given clock. Given the increase in latency pushing past 3733MHz, I opted for B die. I probably would have gone with E die if I want 32GB.

I just want to point out that a lot if not most people here have B-Die memory. People forget ram is ram with a fancy or not fancy heat spreader. With the binning of memory chips today. You really need to buy memory that is actually rated at or close to the speed you are after. Some of this high flying 14-14-14 stuff cannot run stable 14-14-14 @ 3600mhz if they buy 3000 or 3200mhz sticks. The binning of ram has become much more exact than in the past.

What I am running now is the generic Team Vulcan II 3000mhz 16-18-18 kit. It's running @ 15-18-18 3200mhz. I got it up to 3600mhz at pretty loose timings but it was only enough to run a few benchmarks before crashing.

I am simply throwing out my 2 cents before the 3600mhz memory kit arrives. I will post all my results next week.

Well since alot of people on here have B-die as you suggest we can actually test that.

I'm fairly certain Ajay is already there on his kit with 1.4 or 1.45V

 

[DrMrLordX]

I bought DDR4-4400 back in 2018 in anticipation of building this machine. If it couldn't run sick low latencies @ DDR4-3600 or so, I was gonna be pretty upset. Fortunately, it did it's job.

b-die is mostly irrelevant to the market now since Samsung isn't producing it anymore. Whatever you buy is a remnant. You've got to make do with Hynix CJR or Micron e-die until Samsung decides to bring A-die (or M-die) to the consumer market en masse. Right now you can't get that stuff except in OE-style generic PCB units, and good luck finding them.

 

[JimKiler]

I ordered a DDR4 16GB 2 x 8GB 3600mhz memory kit. If I can get the timings to 16-17-17-34 (1T). Would that be good enough for 3600mhz? If I could get those timings @ 3733mhz would that be good enough? Do most here run their Ryzen 3000 CPU's @ 3733mhz or 3600mhz?

Since the Infinity fabric has to drop below 1:1 ratio after 3600MHz i would not attempt any higher.

 

[DrMrLordX]

Not true. There are people who have run IF speeds as high as 1900 MHz (DDR4-3800). DDR4-3733 is usually the rational limit for memOC on Matisse, but that is not always the case.

My G.Skill b-die kit does 3600 MHz CL14 with a slight voltage bump to 1.45v's. Stock voltage for my kit was 1.35v's at 3200 MHz CL14.

I picked up my kit before Zen2 was launched as I originally was going to build my rig with the Bestbuy Crosshair VI Hero/R5 1600 combo that I picked up for $199 on their blowout sale. I paid the b-die tax as I wanted to go with the most compatible offering for the platform.

I remember reading a review or watching a YouTube video that ran the IF out of sync with the memory. It's possible to lock the IF to 1800 and run the memory at a higher clock if I remember correctly. I'll have to try and hunt it down.

 

[Hans Gruber]

If you take your memory speeds and divide by 2. That is where you want your FCLK clock at.

This is direct from Corsair's website.
INFINITY FABRIC – Infinity Fabric Clock Speed (FCLK)
For Ryzen 3000 CPUs, most will run a 1:1 ratio between FCLK and MCLK, which can be considered “synchronous” operation, up to 1,800MHz.

You manually tune them in your bios.

Which agrees with
DrMrLordX

Yeah, I went with 1.45v as per the Ryzen ram calculator. I haven’t had cause to fiddle with that yet. I’ve seen one extreme memory overclocker get those settings down to 12T @ 3800 with some scary voltage.

I've had DDR4-4400 running on my system with IF out of sync (1200 MHz, lulz). It was terrible. There are also some weird circumstances where people trying to run DDR4-3800 with IF @ 1900 MHz will get no gain in performance, even with timings identical to what they had at DDR4-3733. Some quirk of the IMC. Not everyone has encountered that problem. There are a few elite setups out there running DDR4-3800 CAS/CL14, but they're rare.

 

[sdifox]

But what is the actual payback on memory oc?
