Just got a new 5800X CPU/MB and I have questions...

[DanielNS84]

Looks like all 4 sticks are humming along at 3600 c14 quite nicely...memtest finished and I’m about to start running AIDA now with no WHEA issues or anything. I’m only at 1.43v at the moment and memory hits about 44c under load (fans in quiet mode) so should I push further or nah? Also, what latency should I be looking for?

Do what you want. You have the right idea, some information and you take it where you want.

I think Sub 60ns would be suitable.

Aida64 isn't a very good stability test, both for cpu and memory. It's quite weak. That is pretty warm memory though.. you should start considering more airflow at this point..

Yeah I used it to find my latency...the test I use is Memtest86 and I ran that for 4 cycles. If you think I should I guess I can cool it more. For now I maxed out both 200mm fans blowing at them and I ordered a ram cooler, if that’s not enough I’ll either make a cooler (I have a full workbench) for them or order that crazy water cooler for my ram but I like my current water cooler and I don’t think they sell one that only cools the RAM and not the CPU too. I’ll update you guys when it arrives tomorrow from Amazon with what my temps are. I’m running them 3800 c16 at the moment at normal voltage until then.

[DanielNS84]

Okay, I came down to my office this morning and it had run a ton of Memtest86 cycles with no errors at 3800 16-16-16-16-32 1:1 Mem:IF and I'm in WIndows with no WHEA issues so far. Oddly enough AIDA64 shows lower latency than at 3600 C14 which seems wrong but I dunno...posting my results below so maybe we can figure out if this is normal or if maybe something is slowing it down. Once my cooler (I checked and apparently it works for DDR4 though meant for DDR3) gets here I'll try to push farther.

 

Edit: Adding new and old results for comparison...I forgot to save the AIDA64 results @ 3600 C14 but I can swap back to that to get that info if anyone is interested since I saved that OC profile just in case.

 

 

Edit: With my current fans all the way up my memory is at 37c instead of 44c...not ideal as they're too audible for my liking but it works until I get the cooler.

[DanielNS84]

Okay, new cooler for the memory arrives shortly, I'll see if I can tighten things up/raise the voltage a bit once it's here and post back.

[DanielNS84]

Oh wow...so that worked much better than expected...not the prettiest thing in the world but it works!

Temps down about 13-14c at 3800 C16

 

Here it is:

 

I suppose I'll cable manage it later.

 

Edit: Hits almost 31c during AIDA lol...

 

Edit 2: Down to 27c at the moment...maybe it hovers near ambient since it's getting cooler in the room?

Okay, so I’ve been playing with it a bit and got some interesting results. I can boot at 3800 c14 but I get errors at the end of memtest during the hammer section so I chickened out at 1.47v because my motherboard reports that it’s already at 1.5v. Temps seem okay but I decided I’d back up for now and look up different sub timings and settings and after a lot of research and swapping things back and forth I have the same primary settings (3800 16-16-16-16-32) but I manually set everything under advanced DRAM settings and I noticed that the menu in memtest shows drastically different values now. It went from “Memory: 39.3 GB/s” to “Memory: 45.6 GB/s” and the latency dropped from around 60ns to 52.3ns...no clue what could have caused this unless secondary timings are that important? Anyone know?

Ryzen chips really run well at 16-16-16. Stick with it. Shoud prove plenty of stability and low latency.

I'll stick with it for now...at least until I get a crazier memory kit then I'll amp the voltage to see how high it can go. Also, in AIDA the latency boosted back up in Windows but the bandwidth is definitely higher now...secondary timings did a lot!

 

Edit: Closed my running applications and ran AIDA...I feel like this is probably good for now lol.

That's saucy!  Right where it should be.

Better than my Zen+ (2700x) B-die at 14-14-14-34 3733mhz. 

 

Nice work!
