Nice!

It's a good opportunity to do some testing with TM5, more so to make sure you can keep RAM load temps in check. B-die you wanna keep below 50C at all times. Your threshold at the moment might be slightly higher given the low VDIMM and loose tRFC, but 50 is a good rule to live by.

Might be worth establishing a reasonably fast baseline at 3600 that you can always fall back to. Then see whether you need to bump VDIMM a bit, or if you can even shave some excess off the 1.35V XMP. Something like this:

4333cl16 timings - Copy.png


Then tRFC somewhere in the ballpark of 140-150ns, look at the chart to find the number for 3600

Reous tRFC list v21.png


Intuitive as Asus bios is, should be a piece of cake to find the timings.

Now that's what I'm talkin' bout'.

Crank em up. 3800mhz, psshhh no problem CL16. 1.45v.

Limit Dimm load temp 40-45c.

I'm running tm5 tests now (anta777 extreme) so far no issues but the DIMM temps were 50c it seems while running the test , i did notice while installing the kit that it was a bit tight between the two rams.

Yes Trident Z is a bit of a tight fit on 2DIMM boards (that aren't Z690 with extra spacing), and dual rank runs hot. But you're going to have to do something about that airflow. Too hot if you're wanting to get anywhere with B-die. Point an extra fan at it or crank up the airflow.

What's your setup actually look like? All I know is that you run a 5600X in an ITX board.

Living inside a volcano, I see :laugh: how long did you run TM5 for? DIMM temp should take the better part of an hour to actually reach equilibrium.

45C in TM5 at just 1.38V is still warm. My ambient temp isn't much cooler than yours in the summer. Also not even taking into account the amount of heat the 6900XT will dump on the DIMMs when you fire up a game. You don't have to do anything more than stand up a small 92mm fan on the backplate of your GPU and point it at your RAM. When I was running a loop just that 92mm fan alone dropped DIMM temps by close to 10 degrees.

Though, with only a 120mm top exhaust, and basically no helpful intake fans I was able to get down to about 43C @ 1.43V. How slow are you running your fans?

yea volcano seriously. today it was 116 F...
i ran for quite a bit, will run more over the weekend. i forgot to mention i do have 2x 120 on top with the liquid cooler kit., and one 120 under the GPU blowing air up. just loose in the floor . im gonna try that right now ... good freaking tip.
i been having a new motherboard on the back of my head since this build started from a transfer from mini tower and i end up keeping the board..

You won't need to spend a lot of time beating on this set. They'll probably be fine at 50c, but the higher you go v-dimm and frequency, the lower they like to run temp wise. Helps keep stability.

Nice thing is that this kit will top off your Infinity Fabric. Nothing wrong with experimenting high frequency either. B-Die is not impartial to odd memory timings such as 17-17-17 or 19-19-19 4000mhz and faster while keeping v-dimm reasonable 1.40-1.45v should be of no problem. Even do 4200mhz at CL19's 1.45v all day I'd be willing to bet. Depends on that memory controller.

Temps on B-die is something to look out for but some sticks have more tolerants to heat than others.
My sticks have no issues going above 60C. this was with no case. If you have decent airflow in you case then it should not be a problem.

Try
RRDL 4
WTRS 3
WTRL 8

RTP should be 6 not 8. Your aida latency is abit high should be around 54-55ns <---Make this change first and test Aida again before testing above settings

Also try lowering TRFC 272 or 266

Well, I'd be aiming for as close to 4000mhz at CL14-14-14-34 and Start at 1.60v and work my way down. My set, single ranked 2 x 8gb is rated 4267mhz CL-19 1.450v. They have much more capability however. CL16's around 1.50v seems pretty good with mine. I could NOT run these at 60c. They'll start producing errors despite seemingly stable with the everyday tasks. (that's where the testing comes in with tweaking)

Open up Thaiphoon Burner and get a read. I'm curious what PCB these sticks are, something I've never thought about in the last few dozen suggestions or so. With a big please! of course! :)

Yeah, that's a bit too tight.

16-16-16-36 (up to 4000mhz) tRFC in the 400's area. I turned mine out (for Benchmarking not daily) at 444 clocks. Was stable enough to run 3Dmark a bunch of times to produce a decent score. With a 2T command rate (typical for A2 PCB dimms) any ways.

1.38V could be the cause of that I would personally go back to 1.45V. Which is perfectly fine for 24/7 on Samsung B-die.
The lower TRFC can improve latency
This is my daily setup at the moment

tRFC scales with VDIMM......up to a point. You're still pretty low on the volts, bump it up a notch to see if you can do 140ns. 140 is probably where I'd stop for a daily if don't want to pump too many volts.

At some point you'll bottom out with your tRFC number (not ns) and it won't boot regardless how much volts. I think mine are 138ns at 4200 (A0 Viper Steels) to 131ns at 4333 (A2 Viper Steels). I don't think I've bothered to explore my limit on my dual rank 3600CL14 Trident Z as it's my daily but I have a feeling it outperforms both Patriot kits.

Temp threshold (point at which B-die destabilizes due to heat) primarily is to do with tRFC I think. And also VDIMM like shrimpbrine said. 50C seems generally fine at 140ns but once you get down in the low 130s or 120s I wouldn't be so sure anymore, that threshold may come down. 120 is a bit too hardcore for most people and their kits anyway.

55ns isn't bad at all for a mild 3800CL16 setup on 5600X.

yea volcano seriously. today it was 116 F...
i ran for quite a bit, will run more over the weekend. i forgot to mention i do have 2x 120 on top with the liquid cooler kit., and one 120 under the GPU blowing air up. just loose in the floor . im gonna try that right now ... good freaking tip.
i been having a new motherboard on the back of my head since this build started from a transfer from mini tower and i end up keeping the board..

Not lying down. That's just blowing the flow-through hot exhaust from the GPU upwards. I meant standing up a fan on the video card, vertically. So that it blows cool air directly onto the DIMMs.

Hence the suggestion for a small 80 or 92mm fan. Doesn't have to be big, bigger can be hard to fit in there.

Right on B1s.

I'd be surpassing the idea of daily clocks at suck low frequencies though.... But hey everyone is different.

4200mhz CL-19-19-19-19-39 Enable the memory training (if board is equipped) and leave everything else on auto. 1.45v and Uncouple the Infinity Fabric. command rate 2T. Curious if it would just post right up. Compare your numbers linked lower frequency VS Unlinked higher frequency.

BUT Man!! - You've got B-Die!!!!! You are either going to just set this up and go gaming OR you have weeks of tweaking to do. HAHA!!!

So many people jam B-Die and so many configurations.... just how deep is that rabit hole?

Oh and enable "Gear Down mode" in the timings menu as well. You can do Power Down mode disabled, but they might run warmer from it.

Vote #3 for a fan directly on them sticks. (enables spank dimm mode)

spank dimm mode lol

That's why I'll always have a soft spot for Comet Lake. 4600, 4733, 4800 B-die daily setups...then everyone moved to 1:1 and Gear 1 and we never saw that kind of practical OCs again. I knew someone who insisted on 5000+ daily OCs in Gear 2 on Rocket Lake (walk in the park for DJR), but I doubt it ever translated to real performance.

Once you break 1:1 the bandwidth numbers still go up, but basically it'd be like 4533+ before you can even think about reaching parity in performance again. Or maybe I'm remembering wrong and it was like ballpark 4733. Sad.

If @noobzin 's 5600X can do 4000 1:1 though at 1.2V VSOC, a 4000CL16 setup could still be worth pursuing. ITX Strix should have no trouble.

Going above 2000 is great for bragging rights and if you dont get WHEA 19s or other issues. Since he does have a 2 DIMM mobo it should in theory OC RAM very well
and 4200 should be attainable.

Personally prefer 1:1:1 has performance hit when its uncouple is really bad.

Yeah, you're right. My ROG B450-I is a monster.

1.20v SOC may carry the IF (hyper transport link rebrand?) get up to like 3933mhz.... Maybe 1.250v .. 1.30v.. 4000mhz+ ? ?

Going above 2000 is great for bragging rights and if you dont get WHEA 19s or other issues. Since he does have a 2 DIMM mobo it should in theory OC RAM very well
and 4200 should be attainable.

Perosnally prefer 1:1:1 has performance hit when its uncouple is really bad.
You're right really. Even on my 8700K 4000mhz CL16 just seems to be spot on efficiency and performance.

But what good are bragging rights if there was nothing accomplished??

This was I ran daily. (CPU, was just benching the GTX 480 just for some fun)

I agree I would also push to see how high the RAM could go. Some of the guys got 4200 1:1:1 to run using 2 DIMM boards

Not recommeding the OP to try these settings. Veii is an expert at this also this was done with 2 X8GB single rank sticks it would be much harder
to get using 16GB dual rank sticks.

Chances are it shouldn't need that many volts. King's got a great sample there but 1.2V for 4000 is quite alright for samples that can do it without WHEAs.

Though, problem with these 5000 CPUs remains that the VSOC scaling is all over the map......some barely make it to 3800 at 1.2V...some can't even get there...

APUs are a different story. As long as I don't dip below 1.11V at any time, my 5700G does 4333 1:1 all day, all while holding up an OC'd iGPU on its shoulders

I don't know about 4200+ though, even if the CPU can do 1:1. Single rank is easy but dual rank like the kit OP has is a tougher call even on the stronger 6 layer boards, ITX and 2DIMMers

Ah? No comment on the "rebranded HT" part though? I was curious your thoughts... hoping... something might spark.

Not quite sure, but yes the scaling seems all over the place. But so are the makes and models of motherboards and memory kits.

Just sad AMD couldn't keep the 4000mhz+ promise across all the boards *puns

Couple or uncouple, no happy medium....

No bother to me, I'm off to ddr5 and 4800mhz Jedec is slower than molasses dripping from a pine tree in Antarctica. 90+ ns latency. The User has NO CHOICE but to research their purchase and OC back to a more mild climate lol.

And there my 8700K sits waiting for winter F@H. :(

That's a sweet ride man. Many are jealous for sure. When I refreshed there was nothing. excuse the original smiley thing.

And there's that 70c temp too. Nice!

Won't get any positive comments from me, rebranded HT is what Fabric is and sums up what I think of it :laugh: chiplet IF is the el cheapo solution, we won't get any revolutionary memory OC going until big design changes are afoot

Ryzen memory controllers have been strong since 2019 but IF on the chiplet products holds back them back on all 3, clock, bandwidth and latency compared to monolithic IF.
