    The secondary side needs the red marked capacitors and every ceramic capacitor from a spare board (mine was a G20CB rev. 1.02 from where I get every C.

    Attachment 90689

    The electrolytic capacitors must be soldered on the bottom side of the board, otherwise there is no place. I do not have a photo from this.

    To solder the FETs I prepared the place first. You need hot air and a good iron to prepare the surface with solder. After that you simply place the part on the surface. With hot air in that region solder will melt and you got it. Do not use to much solder and use any kind of hotair gun with a very small nozzle to heat only the region of interest. Be careful not to burn and delaminate your board. Here is a photo of the G20CB from where I got the cemaric capacitors:

    For HT you can find it here:

    Attachment 90691
    Attachment 90692

    It is possible, that you can´s see that entries because you do not have access to them.

    I unlocked many features of the BIOS. Instructions for that you find on win-raid.com . For each hidden setting you have to set access mode to "supervisor". I dont remember wether the HT feature is locked or not.

    This helped a lot thank you, and as for the soldering, it shouldn't be an issue, been doing it for years, just to recap I marked the soldered components to be sure in the new picture underneath. And as for the HighSide-FET that you mentioned in your previous reply, I'm afraid I don't understand that fully, or is it the normal fets that you are referring to?

    And it seems like my bios is limited, i used Coffetime 0.99 to modify my bios but there are no additional settings that were unlocked. ill check Win Raid for and check the AMIBCP 5.02.xxx software to see if I can unlock it as you mentioned.

    Do you think you could upload your modified bios ?

    Ok, experience in electronics and soldering are good signs that you will have success.

    Yes, you marked it completely correct. These FETs are Power N-channel MOSFETs from OnSemi (NTMFS4C09B). You can buy that MOSFETs. The current product number is NTMFS4C09N. The B or N at the end does not matter. Each of them has a Id of 52A. DATASHEET

    I thought about replacing that FETs with NTMFS4H01N which has a very low Rdson and a max current of 334A !!!. It may give a bit additional performance at the end because of the very low Rdson, but you have to think about Isat of the inductors. I think with the current modifications we get near or slight above saturation current (Isat). If you want, you can try that NTMFS4H01N. They are available too.

    But don´t forget these four 3V, 820µF Low-ESR electrolytic and the bunch of ceramic capacitors at socket bottom side. These are a must-have to avoid thermal throttling of the VRM (mainly the inductors).

    No, sorry, I can´t upload my bios because of the Windows Product Key inside. But if you wan´t I can modify yours.

    Ah... I forgot something essential:
    You will need liquid metal (Thermal Grizzly Conductonaut for example) to keep CPU temperatures around 70 to 80 °C at full load. With regular thermal compound the temperatures will be 20°C higher resulting in thermal throttling.

    Awesome, ill try source the components instead of the motherboard itself. About the four 3V Electrolytics, what about them? They are there or should i add more of them? "EDIT" Read your comment a few more times, there should be a place for them on the otherside too gotcha

    Ill keep the liquidmetal in mind too
    No worries about the BIOS, and if you can mod mine it would be great, ill upload it later in the day after work

    There are four on the board, you can see them. You need additional 4 soldered lying at boards bottom side so that the board will fit in its case.... ah yeah... you got it. Saw your edit Possibly you can add a 5th to the top side with bottom side in sum 10. It may give you more room to a higher ICC.

    The best way to get the right of them is a spare board. I don´t know the vendor nor the exact type of these electrolytics.

    hey. I found something about the 3V electrolytic capacitors
    APAQ AR5K Series
    Partnumber: 3R0AR5K821M06X8C

    and the 25V electrolytic capacitors:
    APAQ AVEA Series
    Partnumber: 250AVEA270M0606

    Look in the datasheets. ESR and so on is given, so it´s possible to find mating types.

    Great, thanks again, will source them, and as you mentioned, a spare board is the best way to get those. Will get back to you with the bios file later cheers

    Got a bunch of new settings but the hyperthreding seemed still locked, I was on cpu configurations and nothing was there🤔
