Got the Asrock Nova board in. Since my block is an AM3+ block, Aquacomputer said I'd need a retrofit kit for the original Cuplex Kryos block.

Question AM4 and AM5 mounting Identical? Looking at getting a Kryos with the vision on it.

Pretty much, yes Identical.. But what is a "Cuplex Kryos block", a waterblock ???

Yes Aquacomputer's waterblock series. The vision ones have a water temp and other info shown on the face of the block itself. Plus the spacing is a little wider on the in/out ports.

Thank you for the confirmation on mounting.

Lets put this way, its close enough its worth trying to see if it fits. I can't think of a reason it would not work.

AM4 and AM5 mounting are the same. That's why temps on AM5 were as high as they were. AMD had to make up for the height difference with a thicker IHS to keep compatibility.

My block is an OG AM3+ block, AC said it would need retro fit kit. Decided to update the whole block.

If you an AM3+ block, sounds like you need a new CPU and motherboard (and maybe memory)

What cpu do you have now and what do you do with it ?

I have an X870E board and some 7200ddr5 ram sitting here waiting for the 9800x3d to arrive.

My current is my sig rig. Mainly play Diablo4 some Last Epoch, and just the very beginning of BG3. Elden Ring won't launch on the 8350.

Storage will probably be in between the waterblock arriving and 9800x3d. Really want a 8TB m.2 but probably settle for 4TB.

Sounds like you are golden ! 2 4 tb drives ??? or does the motherboard not have 2 nvme drive support ?

6000 is still the most comfortable and realistic, and also the best performing all-around. For example I have to go from vSOC 1.16V to 1.28V (6000 to 6400), and that extra voltage eats into the precious power budget of the CPU, and hamper the performance under 65W mode.

Above 1:1 mode, anything below 8000 makes little sense. 8000 does have merit because at that point memory controller actually runs in sync with Infinity Fabric, but how much vDIMM will that take? Even at 1.3V I see memory temperature approaching (sometimes over) 60C under strenuous load. I have no idea how vendors are selling 1.4V DIMMs and not getting in trouble.

On a second thought, you can run uclk:fclk=1:1 below mclk 8000 since fclk is not fixed at 2000. fclk 1900 will sync with mclk 7600, etc. But vDIMM will still be quite high and I am not sure if it's worth the squeeze.

5 m.2 slots. BUT, I have a 1x PCIE1 sound card that I intend to use. This board has 1 PCIE5 m.2 1 PCIE5 X16 then 1 PCIE3 x16 and a PCIEx1 slot.

Current mobo no m.2 support, Asus CHVF-Z

I have to be careful, and I haven't figured out the right config yet, but I also want to use 4x sata at least initially. I do not want to drop my graphics slot to x8 even though the card is PCIE4, and I don't particularly want to watercool a PCIE5 m.2 slot.

I passed on the Taichi due to pcie lane allocation, I believe the nova will accomplish what I want. All do to a soundcard. I could use an external DAC I won a free one off OCN awhile back. SoundblasterX G6. Actually 2 but due to rules I couldn't accept the 2nd one. I was using a ryzen 3200g laptop at the time.

Either way I will keep the thread updated on progress. Because I will have to redo 1 or 2 pieces of hardline tubing to swap it in. Unless I can find some universal VRM waterblocks that the VRM of the Asrock Nova wifi. "preferred option"

I bought the DDR5 on impulse, due to a report that flash was going to rise, BS IDK. But it was a 7200 2x16 kit, I figured I could tighten timing or try for more head room. will see.
It is a Lexar 7200 XMP/EXPO kit, which someone said was good hynix dies, I don't remember the nomenclature, was on OCN. I think. But after reading some of the success with the 2x24GB kits I may replace. Never watercooled RAM before. I have good airflow anyway.

Having a high speed memory kit is not a bad thing. You will have more flexibility. 7200 rated kit will also likely have some headroom to go higher.

Whether it is a good idea to run at the rated speed is what you should test out.

After playing with memory overclocking on Z3 and Z4 I have absolutely no desire to play with speeds higher than AMD recommended (3600 and 6000 respectively), I'm just tweaking timings. But if I were to buy DDR5 today I'd probably agonize over whether 6000 or 7000 kits (or anything in between) would bring me the best timings at 6000, because I have no idea how these are tested when binned, and the prices are equalizing.

Have a Teamgroup DDR5-7600 kit. Was able to go as low as DDR5-6000 CL26 on a Z790 12700K PC. Didn't feel any difference in responsiveness but when I saw the boost that Alder Lake got from DDR5-7000 in the Techspot article, decided to choose DDR5-7000 as my final RAM speed.

Can't find that article at the moment but this shows the benefit of DDR5-6400 with Alder Lake: https://www.techspot.com/review/2862-ddr5-vs-ddr4-gaming/

Did you forget this is a Zen 5 builder thread ? nothing to do with the 2 Intel systems you mention.

The point was that higher speed RAM may successfully boot at much lower timings at lower speeds. I was just relating my experience and I think I've seen YT videos of overclockers making CL24 DDR5-6000 work with Ryzens. But yeah, I agree I provided a little bit too much unrelated information. Apologies.

Can share my experience on the newest beta ASUS 2505 bios with agesa 1.2.0.2A vs previous bios with agesa 1.2.0.2

Overall memory Performance seems up as ive have hit a new high in regards to mb/s in karhu
Clams cache/memory benchmarks also shows an increase in memory bandwidth while latency stays the ~same as with earlier agesa's
Aida shows ~same bandwidth and higher latency, but as we all hopefully know, aida should not be taken too seriously since its so flaky and easy to manipulate.
So in the end i think this is a aida problem, not agesa problem since performance in everything else is better

Some numbers with ASUS bios 2505 agesa 1.2.0.2A

362.5mb/s over 6.5hours in karhu


Fullscreenshot


Numbers with ASUS bios 2401 agesa 1.2.0.2

354mb/s over 7 hours in karhu


For those interested in Clams cache/memory benchmark, both latency and bandwidth are included for 16core Zen5 above

Did also a new run in the Chaos Corona benchmark which i know scales alittle with memory performance, but saw little to no difference here
  • 9950X (ES)
  • 32gigs a-die @ 8200MT/s CL32-46-40-48-88 GDM disable
  • 2200mhz FCLK
  • Large custom watercooling
Score = 18.2 mil

That was the reason I went with Asrock X670E Pro RS, perfect PCIe layout for my usage.

1 PCIE5 X16
2x PCIE4 X1
1x PCIE5x4 m.2
3x PCIE4x4 m.2
1x PCIE3x2 m.2
I think the Nova is very similar to this board. I almost picked this one up.

Have new water block OTW. Man I hate acrylic tubing now. All because no VRM water cooling. Wonder if there are any universal Heatkiller ones that would fit?

EDIT: M.2 will be either next week, if I can go 8TB, or maybe before on a 4TB.
Any suggestions, on some of the Team Group drives or less expensive ones vs the SS 990 pro or WD Black SNX850 870? I don't recall the secondary number.

Yeah, I know it's crazy expensive.

TEAMGROUP MP44 8TB is not cheap either but you could RAID 0 together TEAMGROUP MP44 4TB for a relatively cost effective 8TB if your BIOS allows NVMe RAID and if you don't really care about losing data when or if the RAID fails.
