Ryzen 7 2700X crashes on at 3200MHz RAM

[milesuy]

I got a T-Force Vulcan 3600MHz RAM and installed it on my system, but I get a RAM error (3 beeps) when it runs at XMP 3596, so I manually set it to 3200MHz 16-18-18-38, but I get BSODs in Windows and errors in memtest86. For now, I set it to 3000MHz 16-18-18-38, and it runs fine.

 

I had asked about this, but the thread is almost 2 months old already. I initially let it run at 2666MHz with my old RAM, but I just sold my 2666MHz RAM modules, so I'll now try running the RAM at higher speeds.

 

Specs:

• Motherboard: Gigabyte X470 Aorus Gaming 5 Wifi
• CPU: Ryzen 7 2700X
• RAM: Team TLTYD432G3600HC19ADC01

Questions:

• Is my RAM modules defective?
• Are there other timings I could try to be able to run at higher RAM speed?
• Aside from timings, what other settings can I change to run at higher RAM speed?
• Does Ryzen prefer more speed (MHz) than the timings (CAS Latency)?

For one your ram is not qualified on you motherboard but i never go by this because that means you have to do the leg work to get them to run.

As far as running them at 3600Mhz most likely will never happen with a 2700x. This CPU has one of the worst memory controllers i have ever seen on a CPU.

 

Is my RAM modules defective?

Most likely not

 

Are there other timings I could try to be able to run at higher RAM speed?

2700x is hard to get past 3000Mhz let alone higher without lossing timing alot.

 

Aside from timings, what other settings can I change to run at higher RAM speed?

Make sure Ram Voltage is set to 1.35v, in your memory timings area make sure gear down mode is enabled, this will help with memory stability. all other setting at default or optimal config for you setup. So no other OCing ect. You maybe able to run a little extra voltage on your SOC to help memory controller.

 

Does Ryzen prefer more speed (MHz) than the timings (CAS Latency)?

2700x benifits more from tighter timings over higher speed. This is true up until 5000 series then it more of a balance.

Upgrade from the Zen+ and you'll be able to run 3200+. Zen+ is known to have a memory controller that's barely able to do 2933MHz properly.

If I upgrade to Zen 2 and higher, can I comfortably run at 3200MHz, 3600MHz or higher?

What does lossing timing mean? Higher numbers like 22-22-22-52 than 16-18-18-38?

 

Follow up question: Does increasing the RAM speed improve performance even if the timings are higher, like from 3000MHz CL18 to 3200MHz CL22, both are around 12 nanoseconds from the RAM Latency Calculator?

Usually you do, but it all depends on the CPU you get, the RAM you have and the motherboard.

Zen3 has the best RAM support when paired with B550 boards (that are great for RAM overclocking, better than X570), and Ryzen usually runs RAM better when using two slots and not 4.

With Zen (1600X) I had to run my RAM at 2666 (default), anything above wouldn't be stable, although I had a decent X470 board and only two RAM sticks.

With Zen2 (3600) I was able to run 3200 with the two sticks on a B450 board.

With the same Zen2 cpu and the x570 board I was able to run 4 sticks 3200 (even mismatched sticks!), and now with the Zen3 (5900X) I can even OC the RAM further than XMP.

To add, I manage to run Ryzen 5 3600 with Corsair Vengeance LPX DDR4 3600MHz RAM (using XMP profile) using Gigabyte Aorus X570 Pro WiFi motherboard. Not sure about your board though, but I think you can comfortably run 3600MHz for any Zen 2 (Ryzen 3000 series) CPU.

your cpu only "supports" 2933mhz officially, so try that.

thats the thing… it wont improve performance.

even at same timings there wont be huge noticable performance gains *if* at all.

 

 

Sure you can get a r5 3600 and run the ram at higher speeds, but almost all gains will come from the faster cpu, again the ram speed related gains are negligible in most cases.

 

 

example from my testings:

 

2933mhz 

 

vs

 

3200mhz = +1FPS in several benchmarks

+*100* lousy points in "cinebench

 

vs

 

3600mhz = +1FPS (again lol)

+100-150 points more in "cinebench" (again…)

 

= shit is not noticable at all in every day usage scenarios, even in benchmarks gains are laughable at best.

 

 

Sure thats anecdotal, but its also realistic, for the average user that doesnt  spend $600+ on a motherboard, $500 on ram and spends several weeks optimizing "sub timings" ¯\_(ツ)_/¯

 

 

(and even then i would argue its not "worth it" for a couple of more FPS, better spend that cash on a better cpu/gpu… )

Actually, you gain slight performance increase, that's why many people said Ryzen loves faster RAM. But do note, the infinity fabric (at least for Ryzen 3000 series CPU) seems to cap the clock speed to around 1800MHz to 1900MHz (which is equivalent to 3600MHz to 3800MHz in RAM). 3600MHz seems to be the sweet spot for this CPU. while 3800MHz RAM may causes system instability.

 

I actually tried 3200MHz RAM and 3600MHz RAM, and using Cinebench r21, I receive a few hundred points extra if I use 3600MHz RAM. Many of the time you might not notice the difference, but higher RAM does help out a little in almost everything. Depends on your application, it can help quite well if you're running production application like rendering or video editing, but for gamin, not so much except the 1% fps and less stuttering.

 

It is also worth noting that rather than the RAM speed, CAS Latency also plays a crucial role on RAM performance. Most RAM, even gaming RAM, has a CAS latency of 10ns (3200MHz RAM has 16 CAS latency cycle, 3600MHz RAM has 18 CAS latency cycle). Getting lower CAS latency can improve a little performance as well.

 

Of course, whether the price you paid for the upgrade is justified for the little performance gained is another story. I mean, if you don't have RAM yet and you want to buy 1, then I recommend going as fast as possible, but if you already have the RAM, upgrading them might not be ideal unless you have liquidated assets in your disposal, or unless you felt that your RAM no longer sufficient for your need.

Oh, Im not saying theres no gains at all (as per my tests) just that its generally not as much as people think and also strongly depends on the mobo… for example my RAM latency in tests is far higher than it should be, and the only real explanation is that its the mobo, a cheap msi b350m…

 

And yeah, i agree generally the timings seem more important , which Ive mentioned (and why guys like GN spend "weeks" optimizing this stuff - on high end hardware)

 

In the end, yeah, its not really worth it, I bought Gskill/B-die ram which i didnt really need but wanted to try out anyways, so yeah, even with tighter timings (by default) i didnt see a noticable difference at all compared to my Corsair Vengeance (at same speed but slightly higher timings)

Yeah, AMD 300 series chipset mobo is technically cheap and low performance. At that time, not many people who buy AMD system will tinker the system like crazy.

I see. Too bad then. But maybe next time you might be able to use it when you get a much more better system?
