Z590 are for 11gen with Gear 1 or 2.
They Have a lot problem with 10gen
thats not true at all. Yes.... Z590 has hidden mem options that only show up when 11gen "K" series CPUs are installed and the mem controller in those cpu's clock a little different then 10th gen, there is certainly no issues clocking ram on z590 with 10th gen. Me personally have my 10900k on z590 with 4030MHz CL15 and getting 36ns speeds. This was faster then Z490 for me

4030 C15 Is very good OC but Isn't an High frequency for 10900k
If you Have a z490 Apex instead z590 in 2x8 Is Easy go over 4533 if you Have a good kit

4400C17 2x16 is 36.3ns for me on Z490 Ace + 10900KF. I mean, it performs just fine. It's just still a shame either my board or my CPU is holding me back from running higher frequencies on this kit. It can do way way more but not on this board / CPU.

I tested the kit at a friend's place in his AMD rig in unsynced infinity fabric (5800X + X570 Strix-E) and it booted 4800C19 just fine and even ran 1 hour of TM5 and HCI just fine on 4666 18-18-18-39-2T but o can only dream of those numbers. 4666C18 does boot to windows, it just can't be stabilized. Instantly spews 50+ errors in 2 minutes. 4500C17 is almost stable, 1 error in 38 minutes, but I can't get that error to go away no matter what I do.

I guess I'm stuck on 4400C17 unless I find a cheap Z490 Apex secondhand. I would instabuy it if one came up secondhand sub €250...

not everyone is going for max speed, nor care about max speed.... Of course apex board will clock ram higher, its a 2 dimmer board. Z590 clocks just as high for mem on 10th gen as z490

They haven't fixed the apex. I can't pass over 4000mhz, because the motherboard go crazy and throw random errors, like 7F or long wait on b4.
But, if it boot in Windows, memtest show no errors.

@Nizzen Have you tried SR d bie 1t on z590 Apex with 10th gen CPU? Last time I did I could not get it working over something like 4000 or 4200(cant remember exact clock) where on previous gens(z390/z490) I had 4533c17 1t stable. My z590 Apex wont even boot 4533c17 1t SR BD for me when using 10th gen CPU.

I'm using z590 XIII hero with 10900k and no problems so far.

What are the issues you mention?

Can you overclock ram over 4000mhz? I've some issue with the 10850k. Sa/io 1.25v.

I'm limited because of the heat in Spain now.

Right now I'm using 2x16GB B-die 4300mhz [email protected] 1.45v.

Much better than mine. Probably my cpu, can't hold high frequency.

My 10900k is a good SP 92.

But as far as I know the SP number doesn't relate to the IMC.

The board should be ok I think. Maybe even better than the Z490 XII hero.

Mine is 79. Not bad for 10850k probably. But, the IMC, seems very bad.

With my 2x16 4000C16 1.4 on the Apex i can't boot over 4533 e requires much io/sa for the same OC at 4400C16.
On the master with 4x8 my xmp doesn't work (4000c17 1.35) and i can't go over 3800mhz.
But was probably a BIOS issue. On 11gen no problem and for this reason i returned them.

It's imc diff, not MB.
Though Gigabutt bios sux.

I know gigabyte Is GARBAGE but i gave a second chance, never again. I had similar issue with z390 aorus Xtreme in 4x8 and my z390 maximus xi Extreme was fully stable at 4533c17 😂
