Looks like Z590 will be end of the road for LGA1200.

In September 2021 Intel will launch it's 600 series chipsets for LGA1700 based motherboards. This will be a major shift for the Intel platform,...

+1,.. we are now in the elite Other Series Motherboards.

I thought it was strange to start a New Thread for Z590 which is basically not released yet. The Egg has Maximus XIII Hero board listed...

Vary nice!,.. The minimal RGB, Distro plate is looking sweet!

Your GPU block connection terminals are different than on the FE block, I like how they supply a set of terminals for conventional or...

@Morph
Did you get your GPU block installed, how's the temps on your card vs stock cooler.

I just pre-ordered the Special Edition Quantum Vector FE block, is expected to ship out in early March....

I still have the 2004 loaded on my system in BIOS #2.

Looking forward to testing the ReSizeeable BAR in March,.. until than looks like,..

The 2004 BIOS for my board is listed as 01/13/2021. I loaded it the morning of the release, noticed issues when running benchmarks, rolled back to BIOS version 2002,.. and now today checking download...

I just loaded 2004 beta onto BIOS 2, seems to be working fine.

Haven't loaded all my old settings yet or ran any benchmarks, as I wanted to Enable Resizable BAR than check Windows Device Manager...

I updated to 2002 this morning, I haven't noticed any issues. The 2002 update is solid on Extreme board.

Last year they talked about a Maximus Z490 XII Glacial being in the works, and a few sites reported that a Z490 Glacial was coming, but Asus apparently dropped the board completely from it's lineup....

I just started working on 4400MHz this morning. I set DRAM @ 1.45V and VCCIO/SA @ 1.3V and this is first boot with everything in Auto.

Going to start adjusting, tighten things up, run...

I do not use MemTweakit. However last I heard it does work on Z490 boards, you can try this version. https://www.dropbox.com/s/x6hy0hrsgu...dk151.zip?dl=0

Currently I'm running 2x16GB memory kit,...

For RTL/IO training my system works best with Maximus Tweak in Auto, than I go into RTL IOL Control, insure all RTL & IOL are in Auto, than scroll down to IO Latency Offset,.. and raise the value by...

Back in May 2020 ITIGIC did a list of all compatible models of Z490 boards with PCIe 4.0,.. and Asus offers support for 15 of it's Z490 motherboards with the Maximus XII Extreme model confirmed to...

I have been following the Guide you posted 12-16-2020 11:23 PM post #422 on this thread.

The Guide lists tRFC & tREFI as third step, with Primary Timings being second step ?

I am...

@n1kobg, my memory voltage is 1.45V, is shown as DRAM on HWiNFO64 Sensor Status above CPU VCCIO.

Thanks for the advice.

This 4200MHz profile is going to be my 24/7 settings, going for the...

The only timings I have adjusted/set in above post are the Primary's, tREFI, and I'm working on tRFC, will be between 378 - 294 when I'm finished testing.

All other timings Secondary, and Tertiary...

So far everything is stable, running 16-16-16-36 CR2. Going to play around with tRFC, run some more tests.

I bumped VCCIO/SA up to 1.25V, running Prime95 now for a few hours,..

The 2x16GB modules PCB is B1 8-Layer, 2-Ranks, they are Samsung B-Die.

They booted Windows just fine @ 4200MHz in Auto settings with DRAM 1.45V and 1.2V SA/IO, timings are loose but stable.
...

Hope so, will be disappointed if not. My kit is out for delivery now, should have it by noon today.

I'm running a temp cooling solution that interferes with first DIMM slot, so could not test...

I should have my kit tomorrow, ordered from the egg a few days ago, with express shipping.

Running 2x16GB with unused slots DIMMO A, B both disabled in BIOS should help stability at higher...

I generally run in default settings with memory @ 3600MHz tuned instead of using XMP.

Time Spy run @ 4200MHz. http://www.3dmark.com/spy/16964375

You will enjoy tuning your memory and checking...

This board will take any value I put in on any timing and not crash at re-start, it will boot Windows every time, or go to F1,.. it's crazy.

Lowering tRFC from 367 only reduces Read/Write/Copy &...

BIOS 1003 is solid on Maximus Extreme XII board.

Loading my old 5.3 all core profile and running Prime95 now,..

I was having same issue with lowering RTL/IO. In Auto my values were 69/69/15/14 and I tried 7/7, 6/7, 14/14,... nothing worked, mem training was listing crazy values that would not boot. I was able...

I swapped out the G.SKILL 3600C14 A1 PCB modules yesterday, and testing a Corsair 2x8GB kit.

Still have a bit of work to do.
