Solved my problem! For XMPII of the Royal 4000CL17 2x16GB kit, I need 1.37 IO voltage set in BIOS to be stable and the board overvolts up to 1.408v according to HWiNFO. Luckily it's also good for 4400CL18. Also set in BIOS is 1.375v SA, 1.35v vCore LLC7, 1.45v vDIMM, 52x multi, 49 cache, RTL INIT 71, Offsets 16-15, and all other RTL\IOL settings auto.

Passed Karhu for 14 hours. 0707 BIOS with default tXP and PPD. Maybe 10850K's have worse IMC's and is why such high vccio is needed.

Overvolting SA isn't possible. Negative loadlines do not exist.
Voltage increase at load is caused by power plane impedance on the Super I/O, the exact same thing that causes Vcore to be higher at load than idle at higher LLC levels (and the SA draws way way WAY fewer amps than core/vcore). So the reading is inaccurate.

You set 1.37, you get 1.37. Try probing it with a multimeter directly on the VCCSA controller chip.

Does this apply for both IO and SA, what you set is what you get?

Yeah. Both very low amperage lines.
I did measure mine on the Z390 Ace with a DMM and setting 1.30v IO results in 1.304v in the DMM, setting 1.35v SA results in 1.358v in the DMM. So it does overshoot slightly but I prefer that. At least now it never goes under what I set so I can rely on it always being enough.

I haven't posted for a long time, my apologies for being away :)
I picked up these g.skill flareX 3200c14 2x8gb (F4-3200C14D-16GFX) from amazon for $99 bucks, such a deal, b-die I'm pretty sure.
So I played with these sticks for about a week -- this (screenshot) is bench stable, haven't tested beyond that yet :)
4600 also looks to be bench stable as well.
Any recommendations on timings would be greatly appreciated!! Much thanks!

RTLs in UEFI are the same, but Timing Configurator shows CH A one less than CH B.

Normal?

That' a relief. 1.37 IO for 4000CL17 still seems strangely high.

With a bit higher VDIMM you should be able to run 4400 17-18-18-38
This rig is for someone living hours away from me so I need it to be stable, but if it was mine, I'd push for 4500CL18 because there's almost no difference between 4400CL18 and 4400CL17 strangely. Granted Aida changes run to run, but when I test it, 0.2 nanosecond difference. Not worth extra VDIMM. 4500CL18 gave like +2K bandwidth.

Looks good, congrats on the purchase (y)
Have you tried the 0088 bios to reduce latency

Looking at the asus max12apex website - all I see are three bios - 0403, 0607 and 0707. Is the 0088 bios for the z490 apex? :)
It's a custom bios with a couple of little changes.
I'm running it with TXP = 6 and PPD = 0 because I game. Settings that aren't available on the stock bios
I'm not 100% sure of all the ins and outs but latency is well lower.
Just a suggestion :)

Trying a little lower voltages on 2x16GB @ 4200c17 F4-3600C16D-32GTZR
Dram 1.45v
VCCIO 1.2v
VCCSA 1.2v
Yet to test with BFV
Edit: BFV 21/2-3 hours (y)

Running 4400 c18 with 1,3/1,3 Sa io and 1,45vdimm.
Dual rank 2x16gb 3200c14 Gskill trident Z.
C17 needs way too much vdimm Not worth it.
Extremly tight secondaries.
67500 read 68500 write 65800 copy 36,5ns.
7/7/7/7.
Msi z490 ace.
Gsat stable.

I tested my 3850C14-15-15-30-300-2T (3800 with 104.12 BCLK) @ 1.55v DRAM, 1.30v IO 1.35v SA with BFV for the first time as well yesterday after it passed 8 hours of HCI and it runs fine. Max DIMM temps 41 and 42c.

Did about 3 hours of Grand Ops and no issues at all. CPU is getting pretty hot tho on my current OC as IO, SA and core voltage is pretty high at 1.32v VR VOut on a 9900K. It is lapped but not delidded at the moment. The Z390 Ace doesn't fit with the derbauer direct die plate. It hits a few components around the socket.

It ran around 72-75c across the cores. Perfectly stable and it doesn't spin up the radiator fans all that much yet as they only ramp up above 76c but still. 75c sounds pretty hot for water-cooling.

Hi. Is there a custom BIOS with available TXP and PPD settings for the XI Hero, too? Anywhere? :)

I don't think so but if there is it will be on HWbot probably
