I used to run factory heat shields, have air on my test bench with 140mm 3000RPM fan it worked very well with 1.50v for normal usage, gaming,.. but not for testing @ tREFI 262143, 32-threads,.. need to lower to tREFI 65528, 16 -threads on air for testing.:-)

I use BartX DDR5 Copper shields with copper shims, old school but they work very well. Shields: https://bartxstore.com/shop/custom-ram-copper-heatsinks-for-ddr5-ddr4/ Shims: https://www.amazon.com/dp/B07B3VC9X2?ref=ppx_yo2ov_dt_b_product_details&th=1 block...

Be careful some DD ram blocks leak: https://www.overclock.net/threads/official-intel-ddr5-oc-and-24-7-daily-memory-stability-thread.1794772/post-29282386

@Veii I have a few hours to go yet for Karhu 20K,.. Guess I should have tried 47, I went straight to 48, and started testing. I will give 47 a go tonight, see what shakes out. :-)

@Veii,.. Thanks for all the help with 8200 profile. :-) I needed to bump tRP, tRCD up to 48. RCD 46 was a no go for Karhu,.. 48 everything is running fine, just passed 10K no errors. (y)

Thanks Veii,.. I think I've changed everything you noted correctly. I was not 100% sure about RAS = RCD+X (12),.. I changed RAS to 58. System is good, shaved a bit off the latency. After finishing testing this profile this afternoon, I will save, and work on RDWR_SG/DG lower.

@Veii Hello, if you have time, can you please look at my 8200 profile,.. anything I can adjust to make better. Thanks :-)

I'm hitting 324W, 93c running Y-Cruncher VT3 benches,..

My 13 KF was SP 97 also,.. perhaps something going on with SP, after swapping out chips. :unsure:

New 14 KF with SP 97 is doing fine on bios 0066, chip has decent V/F point offset for 5800,6000.

I updated ME, 1203 bios on 6/15/2023,.. the new updates are working fine. You need to update MEI>ME>BIOS in that order. https://rog-forum.asus.com/t5/intel-700-600-series/drivers-intel-chipset-mei-vmd-6xx-7xx/m-p/937339/highlight/true#M15405

I bought the Z790 Apex from Newegg on 5/16/23 for $699.99 US. The version is A04, manufacture date 2023-03.

I rolled back to bios 0925 with AGESA 1005 today, much better training vs 1101.

@@Braegnok "very good results, but i think transferrates comes from the 7950x, with the 7800x3D its not possible to get near 100000 MB/s, right=?" Actually yes,.. the 7950X has Lower memory latency, slightly higher memory bandwidth then the 7800X3D.

With a-die you can tune slightly tighter timings at lower frequency's like 6000, 6200, and 6400 vs the m-die bars. I have a few baseline profiles on Gene X670E I'm working on since updating bios to 1101 last week. They are all gaming, karhu stable now,.. need to finish tightening the...

I got the motherboard, memory, aquaero, and primary drive in the Gen-Z2 card today. Started running fan cables, temp, flow sensors, 4-pin to SATA power and motherboard 9-pin USB to aquaero. System is up and running, with no issues. Running default settings the performance and...

Most review sites have just received samples a few days ago,.. hopefully will be releasing gaming, performance and benchmarks on Dec 12, 2022. As far as I know the NDA expires on 12 Dec,.. reviewers will be limited due to time constraints to tests using different CPU configurations, games...

I got the manifold in, and the gourmet for power cables installed on back panel today. Leak test on manifold was good, ready to install motherboard.

The 1000W SeaSonic PSU I tested in AP201 chassis mounts both ways and cable plugs in with fan in or fan facing out, so does my Corsair 1000W. I ended up going with a SeaSonic 1600W external power supply to have the native 12-pin 600W cables,.. but the 1600W unit does not fit in the bracket with...
