    Ryzen will only get one more update on this socket, the 4000 series. Still a really solid board in its own right though.

    Meganter reacted to LukeSavenije in Why group regulated units shouldn't be bought/sold in 2019 (and on)   
    These days the 12v is known to power almost everything: GPUs, CPUs, fans, part of the motherboard, sometimes DRAM (but is generally still 3.3v) and some PCs already fully work with it (converting it on the motherboard normally). This used to be different, with 5v being much more important than it used to be. From almost everything on the board, these days it's main use is powering storage. In this earlier era the "group regulation" design was made, and used for many years, even today on budget units from various popular companies including at the time of writing:
    Be Quiet - Pure Power 11 (300-350w only) Cooler Master - Masterwatt Lite Corsair - VS 2017 EVGA - W1, N1, N2, BT FSP Hexa+, Hyper, Hammer, Raider, part of Aurum Seasonic - S12ii/M12ii Thermaltake - Smart 80+ Xilence - Performance C and many others, which are at the time of writing still widely available.
     
    Problem 1: Group regulation and crossloads
    the main problem with group regulated units is that it regulates 12v and 5v together. as noted above these days the only big use for 5v is part of the motherboard and storage, which keeps the load on it quite low, while modern systems have the heaviest components on 12v. In the PSU world we use the word "crossload" for loading up one rail a lot, while the others little to none (either from 3.3/5/12v). When the 12v is loaded up far enough, the controller can't keep the 5v in control, as they're reported together and starts to go out of ATX specification as the controller thinks it's only rising the 12v. especially since some of the units above don't have undervoltage protection, this can have results from shorter lifespan of components to in very bad cases burnt cables. ATX specification only allows a difference up to 5% between rails. They can also fail ATX specification easily when the minor (3.3/5v) are loaded up, while the 12v is kept at the minimal 0.1a 
     
    Problem 2: Low load operation
    The PSU is required to output voltages while the 12v is at only 0.05a, which is for most group regulated units impossible to do with the crossloading problems mentioned above. not meeting this is again a fail for ATX specification for Haswell.

    How do I recognize a group regulated unit?
    The first way (if you have internal shots) is to look at the number of regulation coils. if two are present, it's a group regulated unit, at 3 it's individually regulated. The big coil is used for 12v/5v, the smaller for 3.3v.
     
    The second indication that a PSU is group regulated is to look at the power distribution label. If the PSU says it can output a total a 600w but the 12v says it only outputs 400w, then that's an indication that it's group regulated.

    Here's some images which hopefully provide additionally clarity to those that don't know. 
    There are two sides to a PSU. Primary and Secondary. Won't go into details on the specifics here, The two coils boxed in red are located on the secondary side. 12v and 5v are regulated on the bigger coil and the small coil has 3.3v. Now a thing to consider here is that there is a secondary topology known as Dual Mag Amp, which has two magamp coils. Better than group regulation from a performance standpoint, but in general, it's not very efficient. I think the most you can achieve is bronze efficiency. Maybe silver. It can be easy to confused the two topologies. Now, sometimes, group regulation could use one coil. I've seen a few very old PSUs with just the one coil. (credit to JonnyGuru.com for this image.)

    Below is a Corsair CX450, Boxed in red are the DC-DC converters. Now, this example shows the coils covered. But usually, the coils are exposed and mounted a daughter board(s). These regulate the minor rail outputs while the 12v is independently regulated.

     
    Final verdict
    If you can, get a DC-DC unit, or at least something individually regulated. If you can't, keept the 12v at a minimal level, for example not combining it with high end or even mid-low GPU's or powerful CPUs. They're simply not made for modern component use.

    It should be silent with the 2x200mm fans but you can't have complete quiet with good airflow so this is a good compromise.
     
    You can add a 2nd 1TB NVMe but one should be enough for W10 + some games.
     
    You can downgrade to 16Gb of rams and get a 2080S instead for 2820AUD (this is another PCP  link).

    Avoid making the same mistake i made a year ago, get the extra 20$ and buy the MSI B450 Tomahawk.
    I can assure you if you get the Asus B450m prime you won't be able to get a decent OC on with a 2600, and the VRMs are probably be running hot and unstable. If you don't have the money to buy a decent board, you should wait a little longer.

    i dont have any good guesses. im pretty poor when it comes to troubleshooting. 
     
    by guess is that it is possibly the driver, the card or the mobo causing it. 
     
     
    all i can really suggest is DDU and hope that solves it. see if reducing the powerlimit helps. 
     
    check using superposition if its Vram related.
