Z590 & Memory Support

[Micas]

Hello all,

I've just completed building a new system with the Maximus XIII Hero, and I'm having a problem with the memory. I'm using the same kit that worked with the Maximus X. It is 4 DIMMs of G.Skill F4-4133C19-8GTZR. It's not on the QVL list, but similar to G.Skill parts which are on the list. The issue is that the memory works when using 2 DIMMs in single channel, but when trying dual channel, the system fails to post with a code 55. That happens with both standard timings and XMP 1. I've tried all the currently available bios' with the same result. The CPU is a 10700K.

Is there some solution to getting it to work, or will I need to buy a new kit of memory? Quite a bit of cost associated with that. Thanks in advance.

Hey there, do you have the latest bios flashed ?
Try flashing or even re-flashing (0402) bios, and the do a cmos clear.

I've not had any success getting the memory to work in dual channel. It doesn't appear that the bios allows re-flashing 0402. Clearing CMOS doesn't help. I've tested each stick individually and they work fine, both standard timings and XMP 1. It works with 2 DIMMS in single channel. It's really quite baffling.

I could buy a new kit from the QVL list, but if there is a flaw in the motherboard, it would be wasted money. The memory should work in dual channel. I have no idea what to do now.

Is this another Beta Bios (0610) for Maximus XIII Hero ?

I wouldn't recommend flashing anything that is not officially confirmed by ASUS. I mean i don't know, could be just fine. It's just... Last time i tried to upgrade from Bios (0402) and flash the Beta Bios (0603) it completely broke my computer, couldn't even post and had to do a roll back to 0402 with Flashback.

The Bios 0610 runs much smoother then other ones

it sounds like pin connection issue, reseat the cpu in the socket

Hello Micas, I like to provide some tips.
The IMC memory controller on CPU is running at 2933Mhz with CPU so you are actually overclocking when it runs above 2933Mhz.

First of all, DId you buy the F4-4133C19-8GTZR as a dual channel kit or single memory module? Usually the F4-4133C19-8GTZR comes in 2 which is F4-4133C19D-16GTZR
For dual channel, please install A2 and B2. If it doesn't work, please try these steps:
1) run at 2133Mhz with A2 and B2 and see if it works
2) If it works, please try XMP
3) If XMP profile doens't work alone, please keep XMP enable but manually lower the DRAM frequency until it boots properly and no qcode 55
4) If you want to go higher than step 3, for 4133Mhz or higher ,it requires increasing CPU VCSSA voltage to give the processor it needs to boot propery and be stable. If you want to keep the step 3 DRAM frequency if you want less stress on the memory

I've flashed this BIOS and the MB runs great. It updates a lot of stuff inside the MB. Can i ask how did you find this updated version of BIOS ?
It doesnt appear in the official support pages of the ASUS website.
