Hi All
 
I have a Z490 motherboard (with i9 10th gen, GSkill 32 GB RAM (3200), RTX3080 FTW3 - nothing overclocked yet) and it boots fine, seems really stable while under regular use, no unexpected behaviours or errors even after hours of intensive use. However, a minute after logging into Windows (and getting a few USB connecting bleeps) the AO postcode changes to 52. I believe this is supposed to be some kind of memory error but the BIOS and Windows show the full 32GB and the correct clock speed (XMP to 3200 MHz). Is code 52 just telling me that XMP is being applied? Everything is running fine, just worried something might blow later!

    Welcome to the EVGA Forums
     
    52 could be your CPU Temp (in degrees C) if the PC is running OK

    Hi Thanks for your reply. The number never changes though. 
     
    The temperatures have been good under load, typically in the mid-50s or below when playing games. The max temp under the intel stress test was 78C. 
     
    Interestingly, when booting up the computer to write this reply, I did not hear any USB chimes and I did not get a 52 code by a 04 (or D4) code. This is a "PCI allocation error". Again everything seems to be working fine. No weird crashes, video card seems happy and content, I can see my water cooler (H100i) pump speeds and connected fans. I have a 850G* EVGA power supply <edit> just heard a USB chime and now got the 52 code back. It has to be a PS or USB issue I think. (However the last time I built a PC was in 2001 so you're probably correct!)

    Found this ---> POST code 52 -->  Memory initialization error. Invalid memory size or memory modules do not match.
     
     
    Cold Boot -- MB needs to do Memory training
     
    Is your memory set to XMP ? - if so try setting Manually Timing & Volts per label on RAM
     
     What exact Part number is your RAM ?
     
     
    Which MB ?
