That's what I wanted to hear. Many thanks.

Very interesting that we do not have to worry about memory speed over 3733mhz going into a-sync mode for the fabric when there are two CCDs.
Yeah two ccds also has memory write speed advantage(if that is advantage?)

I'm curious about ccx latency. 3900X latency increases when you use 4 cores or more, 3700X and 3800X has the advantage of additional 1 core per ccx. You have to utilize 5 cores to increase that latency. When you think about applications and games i assume 4 core utilization is common. So i think 3700X may have latency advantage in some cases.

Also another advantage is fabric overclock. I assume 3900X with 2ccd and 12 cores may have harder time to overclock fabric speed.

Hey @elmor -- would you be able to setup RAM drives and do CDM and/or AS SSD benchmarks between the single-CCD and multi-CCD cpus? Curious to see how the half-write bandwidth affects RAM drive speeds.

Timing results at 3600 MHz with 3900X, much smaller difference than expected until tuning subtimings and setting GearDown=Dis. In the "tuned" result I used the "4000MHz 1.5v 2x8GB B-die" profile and manually set the primary timings.

Sorry I think you'll have to ask someone else to test that.

Oh baby, I know who's timings I'm going to be blindly copying sometime soon.

Actually this is the reason I am waiting to see if the 3950X beats all the other 4000 series chips. Advantage of lower latency + higher boost clocks + write speed. I am guessing that the fabric overclock will not matter much at around 3600 1:1 anyways.

The problem on my end is I'm using C6E which has a woinky BIOs on 1.0.0.2. Gotta clear CMOs if RAM fails to boot. Even at DDR4-3200CL14 with tightened sub-timings, it's giving me problems if I disable GearDownMode when it wasn't a problem whatsoever before. Stock subtimings works without GearDownMode but tightened subtimings was a no go until GDM is enabled.

Best I can do with DDR4-3600 with tuned sub-timings on B-Die (GDM enabled so that's at least a ns or two I think) is ~69.1-69.3ns (did do a 68.5ns run but that was an outler):

From my R5 3600 it seems that 3600MHz 1:1 is very easy to have on Matisse. I'd setup 3533MHz using The Stilt's 3466MHz timings last night, I only had to bump VDIMM from 1.35V to 1.355V. I manually set SOC same as what I saw at default, set CLDO_VDDG ~40mV below SOC.

AIDA64 Bench (Latency is higher than PR though at same clocks/timings, etc)



RAM Test 1200% last night



RAM Test 2400% on full POST after shutdown overnight.



Same POST rerun RAM Test 1200%

Good effort! I have my 3900x coming in a couple days and wondering how my x470 Gaming 7 (t-topology) will handle 4x8GB (3600C16D-16GVK), also Looking forward to tweaking sub timing to see how far I can get the latency down. I will probably try it out with stock cooler to begin with then throw the custom cooling I have ready for it on once im sure this board will behave itself.

Also anyone tried BLCK overclock? Think on my 2700x I only managed a 100mhz OC before the NvMe drive started to **** the bed.

very good thread. Im still thinking about benchamrking Matisse on X470 (Win7 support of chipset).

Elmor, u are true AMD fan Again u are doing well to support for Crosshair board, for fanbase and in your free time Excelent.

btw. do u have some tips for LN2? I saw guide from safedisk, but maybe u know another helpfull tip Thanks.

I tried a lot or runs this morning trying to keep as low SOC/CLDO_VDDG/VDIMM (1.043/1.003/1.365). RM shows some info wrong but still has a lot right and currently only util with some settings readback.

Hmm good results! Also saw your other posts reaching 1600% with Ramtest...
I didnt find any time to stress test my memory. Will do soon. Looks promising for now Yesterday i was playing with PBO settings, got multicore boosting a bit higher but SC boost seems to be locking at 4.4Maybe im missing something, but again didnt had much time to play..
