After a couple of weeks tweaking, I think I am at a good point considering ram is 4x8gb Hyper x (not a kit) and it won't boot above 2666, and one of the dimm slots on the mb seems to be dead, I tried tightening the timings and was pretty impressed.

What's your RAM and ICs?
You should be able to tune that latency quite a bit by tweaking the timings.

covfefe lake.

Might want to tweak the Uncore/Northbridge next; not sure if it does all that much though.

E-die is amazing!
3800MHz CL16-16-19-16-36
R5 2600 4.1GHz

Actually scratch that previous score. Didn't touch sub timings previously.
I don't have much to say really

The old boy has served me well in the past 3 years, but it's time to go to Ryzen gen. 3.

Still not too bad considering the age.

Actually DO say some more about what you did to the Subtimings.

Currently I am at 4480 @ 17 - 17 - 17 - 35.
Scrolling through this thread I think that should result in a latency around 35ns.
However my latency is around 45ns. (And Bandwidth is also lower than 3 posts above)
Someone got an idea whats wrong or whats limiting my latency?
(Motherboard is the ASUS Z390-I ITX)

It is obvious that in the secondary timings (tRFC, tREFI, etc). But reading minds is not my forte. In fact, each processor-memory-motherboard bundle has an optimal speed, which is not maxed as possible, since secondary timings are important. I can run my memory up to 4600, but I achieve this result via applying BIOS OC preset for 4100 and adopting it a little for 4300. For everyday usage I loosen it a little, but latency still 36 to 37, 64 reading speed.

^ this.

Post your secondary timings... a small cut to trfc alone can shave off 5 ns.

Thanks for the answer.
I played around with the secondary timings and achieved some improvement.
I also overclocked the cache clock from 4.3Ghz to 5.0Ghz, which gave me a couple nanoseconds.

Currently those are my settings:

I dont really get tRFC any lower without losing stability.
Still playing around to get latency even lower, so suggestions which timings could go lower are very much appreciated.

what voltage do you need for that clock?

May I ask what your subtimings are? That is a nice latency for first gen Threadripper.

I started to tweak my memory too and I´m trying to learn what all the numbers and letters mean and my result looks a bit different:

Sorry only trial version for now, this months budget went towards B-Die

My latency seems suspiciously high? Considering that I run the same primary timings and much higher frequency? How far did you tweak subtimings to get this latency and is it beneficial in any real world workload?
I suspected that I hit some instability maybe, but so far an hour of memtest passed without any error and my benchmark results all scaled well with higher results each time I went up in frequency.

This 4400Mhz 17-17-17-34 latency score with ring bus set at 45. Fairly certain the score would improve if I OC'd the ring to 49. Oh well, its a 4600Mhz 18CL B-die kit that feels so much zippier and responsive at 4400Mhz 17CL.

The kit also runs nice at 4400Mhz 16-17-17-34, yet won't pass memtest HCL at 1000%, errors at about 400% - still feels amazing though, and no data loss whatsoever.

Haven't tried the 4500Mhz range yet, still something to discover.

Ran AIDA64 at 5.3, 5.4 and 5.5Ghz, to see if any real difference in the mem latency score. Nope, all three scores were plus or minus one tenth of a nanosecond, 37.3ns, 37.5ns, 37.4ns respectively - probably just margin of error.

Does that say your uncore freq is 3.7?

 

[E-curbi]

Does that say your uncore freq is 3.7?

The north bridge clock? Hmm is that uncore?

Checked back at the other two AIDAs I ran that day, and they all say 3.7Ghz northbridge. Is that bad or good? I have no idea.

Here's the other two runs at 5.3 and 5.4.

It's your cache clock / uncore , and you can probably run it at 4.6-4.7Ghz with no issues, it might lower your latency a bit. Might be worth a shot.

Mind doing another run with north bridge/cache Clock overclocked to 5.0Ghz? Would be interesting to see how much this improves Latency. I gained quite a lot by overclocking that.

Sure, I simply move the ring bus up to 49 or 50?

think it's set at 45 right now, part of the Luumi Daily OC Preset that arrives with the bios for the motherboard.

Did I have it set at 37 default that day???

northbridge, ring bus, and uncore are all the same value?

BRB.

--------

First screenshot is ring bus at 49
Second screenshot ring bus set at 50 in bios.

Latency went up.

And no idea why northbridge reads 3999Mhz and 4002Mhz, If that's the SAME value as ring bus. Maybe AIDA64 is not ready the Z390 Dark properly? idk.

Have the latest bios installed for the mobo.
