...almost finished with 'operation integrate' of the Aorus 670E Master / 7950X3D into my dual-mobo 'daily' setup. This was very tricky as this X670E board is the wider e-ATX format which replaced a regular ATX mobo that used to reside there (talk about tight quarters! ). The insert pics show a.) the Arctic P12 pst right above the DDR5, and b.) the bank of three 480 x 64 triple copper core rads (push-pull fans, three D5s) that cool the 670E/7950X3D combo. The system on the lower right (X570 Dark.H./ 5950X) has a similar but slightly smaller-capacity loop (three 360x63 rads, two D5s).

...should be interesting to see where / how they price it, along with the motherboard choices. Like with previous TR Pro releases, initially, these new CPUs might be OEM-only (ie. Lenovo, HP) but a few months later, they probably become available to the public, though perhaps AMD will follow a different pattern this time around. Also, there was no mention of 'overclocking' (as in un-locked, unlike their AMD Epyc server counterparts). Hopefully, overclocking will still be an option, though these are power monsters and require top-shelf cooling. The 8 channel DDR5 variants would be my choice - hopefully available for the 32-core '7975' as well because that would be a real work-play monster. -
FYI. I have linked > Buildzoid's DDR 8000 / Ryzen 7900X a few times in this thread...very much worth watching, including his comments re. single chiplet Ryzen 7K and bandwidth, as well as voltages and such. In any case, it takes a certain masochistic streak to tune-test-tune-test RAM - I remember finally getting to a solid DDR4 4000 w/my 5950X...did it make a difference in most games compared to DDR 3800 ? Nope, but it was (mostly) fun getting there with limited voltages. ...now, with DDR5 8000 locked in on the 7950X3D, I like to go higher - I briefly hit an even 8200 CL 36 at the same voltages as 8000, but 8200 only lasted for a few seconds. 8110 can run 'ok', though it will eventually throw errors in long stress tests since I use the same voltages as 8000. I could go a bit higher on voltages, but then again, the new bios for this board supposedly has even better RAM oc but as posted before. I just rather wait a bit for them to iron out the new-bios-bugs. I am pretty sure that by this time next year, we will be chasing at least 8400; probably more...

Which bios ? I am still on 13c instead of 13d, because bugs usually accompany a new bios release...

...I got my 670E Aorus Master on sale as well, ditto for the RAM. BTW, in addition to Neurotix' suggestion, Techpowerup's memtest64 is very good and, well, stressfull judging by the CPU and DDR5 temps it can generate. 10 error-free loops is what I use as the 'pre-screen' for shortlisted, potential RAM settings. This test will start to fail after 4 - 5 loops if your DDR5 gets too hot / has not enough airflow. Then there's the old stand-by: y-cruncher, it will reboot your system if you are too frisky with your settings, and of course OCCT's RAM tests, including Linpack. Finally, with a single CCD CPU, going to 1:2 does not make sense according to Buildzoid as the latency 'cost' cannot be outweighed by the potential benefits. So focusing on tight but safe (voltages, temps) primaries and secondaries is the way forward, IMO.

...the 670E Master has quickly become one of my fav boards, especially from a price-performance POV. It does come with 'eclk' options rather than just 'bclk' and has a great memory topography and the full PCIe 5 treatment. It does have it quirks, for example, the CMOS reset is via a jumper / bottom right of the board, instead of a button on the IO panel. All in all, a great X670E option.

On my 24 GB cards, I have seen 15+ GB allocated and dedicated (CP 2077, path traced, native 4K)
-
...good to see the competition for pricing impacts in the industry, but personally I would not buy a card with at least 16 GB VRAM

first one = timestamped

Crysis remastered with ray reconstruction and path tracing ! Neat:

Crysis 8k, may be ?!

...speaking of price, some hvl 100 PCI Hopper with tons of HBM VRAM - 32K games and vids, here we come...

...also 'works' on my 6900XT

As @The Pook mentioned, the DDR5 scene has been much murkier to unkey as of late and 'id' than DDR4 was (I only used GSkill Samsung-B - GTZR on AM4, Intel CPUs). Re. DDR5, I have a new 2x24 GB GSkill M-die kit and couldn't be happier, whether running at > CL 36 8000 or CL 30 6400. Some earlier results I posted > here, > here and > here (1:1, 1:2). All that said, technically, my one and only DDR5 kit is Intel-spec RAM but XMP does show in the bios of my 670E Master / 7950X3D combo as an option and works fine. Same story before with my 5950X DDR4 CL14 4000 - Intel-spec RAM . If both the die designation and 'EXPO' are important to you, I would make a short list and contact for example GSkill and see if they will confirm (they should know, given serial numbers and production date)...
-
...fyi, there is also the 'old' M-die and the 'new' M-die differentiation...

Apart from the particular RAM sticks you have, a lot also has to do with the specific CPU's memory performance, and of course board topography and even bios version. I usually shortlist 2 - 3 potential settings via initial RAM tests, ie. 10 loops of TPU/Memtest64 error-free. Then I run each of the settings through some memory-sensitive benchies and games, and the 'winner' gets the long stress test treatment. If that doesn't make it through long tests w/o errors, the runner up gets a try... Without short-listing first, you might be doing this for weeks.

RAMitis for sure ...nice timings, and for MEM VDD of 1.55 V, I think you mentioned the extra cooling you added for the RAM. For the secondary and tertiary timings, I would go with Buildzoid's Hynix-A-die YT above. The 6400 I showed was using @kaliz 's timings to give you context. The 'new' M-die I run is very good for higher bandwidth (7600+, 1:2) but A-die is probably better for 1:1, given what I have read.

YouTube is being stingy, only 8K max on YT which my GPU does support

...what, no 16K HDR card ? How do you make it through the day ? ...and some 7 hrs of 4K / James Webb

...One of my fav Z790 boards, though it will have a short life span (Intel 14th gen) - one reason why I went the AM5 route recently ...btw, I do hope they fixed the Formula's 'corrosion issue' the Formula Z690 had, per Asus' site: "Developed in partnership with EK, the CrossChill VRM thermal solution on the ROG Maximus Z690 Formula uses a new electroless nickel plating. In certain configurations, this plating can break down, leading to galvanic corrosion inside the block's water channel."

I hope you folks don't develop RAM_eritis; I have seen that before, it is hideous For example, if you dream that you have to pass 666,667 % of RAM stress test xyz, call 911... Below on the left is a quick test with @kaliz 's suggested timings for CL30 6400 (using the same 2x24GB new M-die kit as before). I didn't translate all the voltages and timings but it is serving as a good basis for comparison to my regular 8000 settings...an irregular, non-optimized 8100 is also there for fun. I even have quite accidentally seen an even DDR5 8200 in Win 11 Pro, but it didn't last very long. The CPUZ items at the lower right just show single-thread performance with CCD 1 (speed) and CCD 0 (VCache).

My primary RAM test tools are TechPowerUp Memtest64 (lower left) OCCT, including the Linpack, and Y-Cruncher, with some SuperPi thrown in. Each can be varied re. loops / length all the way up to infinite (not that I would, but I could...). My version of TM5 has a severe security issue, probably because it was downloaded from a questionable site (did check first, though) --- it attacked Win 11 tpm

...I have exactly one DDR5 kit, that's the M-die. But here are some goodies for Hynix A-die on Ryzen 7000 from Buildzoid. Also check if he has done a newer vid on that combo (this came to mind first). This is in addition to the excellent advice @kaliz has been giving...
