Hi, yup mine is as I read when the 690 boards came out they didn't seem to handle 4 slots very well, (I've got 790) bit of marketing lying going on with these boards I feel, when the 24gb chips came out I got 2 sticks  total 48gb, corsair  on the website its states they are compatible on the 8000hz chip page, however can get to 74 but freezes, anything above wont boot, and best stable is 7200hz really annoying

[Corrupter]

same only stable at stable is 7200hz.

Hi

The 1801 version is a major update. It upgrades the CPU microcode to version 11F (for the i913900K). As it is stated in the Intel Core Processsors datasheet (volume 1, page 81), everything above 4000 MHz  (1 rank ) and  3600 MHz (2 ranks) is beyond the specs when using 4 UDIMM sticks.

Regards

Hi there thanks for the reply, I'm using 2 sticks, on the ASUS website it says overclocking on the ram in excess of 7700hz,  I cant get above 7200 on the ram without crashing despite the ram being specked at 8000hz,  and on the corsair website for dominator ddr5 says its compatible for the board I'm using,  the CPU however goes in the touch of 6ghz and is contently at 5.5 to 5.8, I was hoping 1801 had the fix for this but alas no

This version seems quite stable and previously my memory would only run stable at 6200MHz, and now will run at its rated speed of 6600Mhz.

Unfortunately the WHEA-Logger errors remain unless PCI Express Native Power Management is disabled.

Hi so, I had a 1300K, and after multi performance issues, and after replacing RAM, PSU, and reinstalling windows, I finally found out that my CPU was the culprit, there appears  to be a memory controller fault on some 1300 CPUs  that gives blue screens, random reboots, freezes in games, and crash to desktop, I have done a warranty return, sems the CPU has been tested, and I am in the process of getting a replacement, I had replaced with a 1400K in the mean time, so will most likely sell the replacement on e-bay as it seems I might get new for old

CPU: 13900K
Memory: 4 dimms of DDR5-6600

Just updated.
Seems more stable than previous versions.
On previous versions, I wasn't able to go over 5200MHz DRAM Frequency.
I now set it to 5333MHz and it works.
Might try higher value when I have some time.

Like in previous versions, I set to:
- XMP I
- Chnaged only Dram Frequency
- PMIC Voltage: By per PMIC

CPU: 14900K
Memory: 4 DIMMs of DDR5-6400 (G-Skill RAM on the QVL)

• I have DDR5-6400 running stable on XMP1 / 5600MHz with this latest BIOS.
• I was only able to get 5200MHz on 1501.

I have a ticket open with ASUS and their "lovely" support looking to see if they can supply a proper voltage configuration. My guess is it will stabilize with future BIOS revisions.

We paid for a decent board and cannot use it as advertised. You can't say it's spec'd for 192GB of RAM and expect that to be satisfied with 2 modules. It's false advertising.

Yup agree, cant get the advertised Ram Speed, Bios has taken ages with lots of updates to get stable, I've always gone Asus, but will seriously consider on the next upgrade, if its ok let us know how the support ticket goes, have a happy new year all
