New high, or rather low score as the latency is lower lol.

 

only thing i changed was from auto to 65k refresh, the maximum. 

 

tFAW cannot be lower than 20 sadly as the bios won't let me. 

It is well known for Zen 4 to change tREFI to 65535. On Asus boards (what I have), it gives like 20000GB/sec more bandwidth. That's only on Asus boards but I am unsurprised to see you getting better results with it set that way. Good job

I don't understand the whole P-Core/E-Core thing, I don't understand their RAM timings, and Z790 is a dead platform so your buddy is going to eventually need a whole new motherboard.

I bench and they are way better for benching, especially the older 3dmark benchmarks, 3dm11 and older. However, I wanted to support AMD and while Zen 4 is a marginal improvement over Zen 3+, Zen 5 is supposed to be fantastic so I wanted to have an upgrade route.

Intel finished 2nm and 1.5nm fabs in somewhere like Ohio that are due to come online in 2025, Zen 5 will be out by then, and I'll find out if I made a mistake.

Personally I would really like to see higher core counts on Zen chips, something like a 24c/48t for $750 and 20c/40t for $500 to replace the 32 and 24 thread offerings now.

Thnx, 

 

Ye i hear such a thing that there is always an penalty with duo CCX CPU's. I heard multiple people about it and latency is the most important thing for me so i guess i made an good choice. 

 

 

A lot of people neglect inter-CCX latency too. (The time it takes data to cross the Infinity Fabric to another CCD) Though, I am not sure what settings optimize it besides raising fclk. The old Zen 3 Ryzen DRAM Calculator had a inter-CCX latency option to test it with, but I have no idea if it would work with or would be accurate with Zen 4.

...with dual CCDs, it is a bit of a tradeoff between bandwidth and latency, though 'I can live with it'. Per earlier post in this thread, 'nothing' will beat the latency in the lower screen 

 

 

Nice. 58ns. Too bad my sticks or IMC isn't stable at your speed and timings. However, the difference for me between 7600 and 8000 was like 97GB/sec to 99GB/sec so I don't think I am losing very much performance.

As I've said before though, for me going from 6200 to 7600 has made a *big* difference, like 10 more FPS in Forza Horizon 5 benchmark. Higher minimums, higher framerate in Quake II RTX @3440x1440 144hz. I also love the RGB on the ram and it works with Asus' Aura Creator too.

That good huh? Good to hear man! 

 

All thanks to you guys really! I am very happy with it, never had a single issue so far. Passed everything. 

I *think* maybe Fluxmaven, who also has a 7700x (or did) may also have posted an AIDA with that low of latency. But I don't think Flux follows or posts in this thread. The single CCD chips can get lower latency afaik. But it's looking pretty good to me.

You're at sub-60ns, that's a really incredible overclock, that's literally like the only AIDA of Zen 4 that I've ever seen with latency that low.

I'd set it and forget it and not worry about lowering timings further. That is an excellent overclock and should be great for gaming or anything else you do, assuming it is stable.

@Hurricane28can you post your AIDA64 again? Also let Windows be booted for at least 15 minutes and you'll get more accurate results as if you do it when you first boot it's still running a lot of background tasks and phoning home etc

Sure thing man,

 

 

Looks good to me. You should probably be sub-62ns timing in AIDA64? You're at cas 30 already. The other primary timings look good even though 36 or lower is ideal. Try lowering tFAW to 16 and tCWL to 24 or 20.

I couldn't even run 6400 on my B-Die kit, but had lower timings at 6200 before I upgraded to what I have now.

Thnx man, 

 

I do think i have a nice CPU, ram and motherboard combi tho cos 2133FclK is not too shabby imo. 6400MHz cl30 is need too.

 

I tried the other more tight timings but for some reason i couldn't boot anymore so i went back to other timings and been stable ever since. 

 

Still need to test 64GB tho but perhaps better on new AGESA. 

 

Can you post your ZenTimings of what you're running now? I'm sure they're in this thread somewhere else but I can't be bothered to read back and find them.

I have it but haven't tried OC'ing my memory since I updated, nor trying higher fclk. I require stability for folding@home 24/7 and Samba server for streaming to Raspberry Pis in Linux. So I stick to what I have that's proven stable, 7600MHz 36-45-45-45 and 2100fclk.

I *can* however remark that post time even from a cold boot is greatly decreased, from like 15sec to train the ram to like maybe 5 seconds tops total post time. With Memory Context Restore on.

Also @Hurricane28*shameless plug* take a look at my G.skill Flare X kit on sale in the marketplace here. Those timings I gave you (30-36-36-36-108-4-6-16) were from that kit. It's not RGB but it is Samsung B-Die DDR5 and is really good at 6000-6400 if you are after low timing at those speeds.

Good luck man.

@J7SC_Orionruns his RAM at 8.1Ghz, people do it here too. No longer an OCN reader...

Also I can run 8000 for benching or gaming but it won't pass my stability tests...

Wonder if Zen 4 is even capable of clocking it that high...

Won't be me, not this time. 4090 hasn't been folding

Why not? Too much power draw?

I'm in 2nd currently but pretty sure PaperClip, Flux and possibly Avacado will pass me by the end of it.

I run an RTX 4090 overclocked in Linux 24/7.

I'm pretty sure the PPD is significantly higher. Though how much, I don't know. I can say that most people say a 4090 should be good for 25m/day the most I've ever done is 36m *actual points* in a day. If I'm lucky with WU assignment lately, I can do 27~28m points in a day. If it's a bad day I do 22m or even just 20m.

Got both cards running and overclocked. The 3060 is OCed and crunching in Windows in my wifes rig.

About 24 hours to go, yeah!

I wouldn't try the timings I posted with four DIMMs.

GL if you try them.

sorry for the noob question, but what are those 4-8-16-4-16-(120ns)-384  timings for? There are like million timings in there xD 

He's talking about tRRDS, TRRDL, tFAW, tWRTS, tWRTL I think.

Check out what I just posted above this though.

@Hurricane38

These are the timings I used at 6200MHz when I still had B-Die in my system. They are very good, quite tight timings. See if they work for you. I was using 1.435v VDD and VDDQ.

How do you know so sure? I mean, is this even good? I think its pretty good as i am not even on the latest AGESA which also provides better RAM OC. 

 

I will try them tho, why not lol. 

 

What about the voltages? I mean, is this 24/7  usable or? I mean save etc. I need to find a way to cool down the ram tho. 

Try them with 1.435v VDD and 1.35v VDDQ.

And yes they are good and going to those timings, if stable, should lower your latency.

Agreed with Kaliz suggested timings for you. Ideally you'd want to be at cas 30.

Also, nice score in y-cruncher kaliz. I didn't realize when I benched yesterday that you can submit them for the Country Cup. I may have to do that.

Tried your timings and voltage and here is the result: 

 

 

Yeah your AIDA score is a lie. No way you have over 100GB/sec copy.

Happy to help.
