i am expecting *anything* from this table (have all RAM removed now) but the singular tiny click remains all i get
why are there jumpers on the front panel audio connector.
well im running out of jumpers to toggle and still no actual sounds
asus website says the 2400+ is validated since BIOS version 1004/1006 (depending on the CPU revision i guess). is it possible that if my BIOS isnt up to date, the board doesnt get far enough to even beep?!
the CPU stays ice cold even with the board powered on for a while. for whatever thats worth
this person https://www.vogons.org/viewtopic.php?t=56372 mentions about their build that
"Its not flawless, but given the power situation with Socket 462 and Modern PSUs, I feel this build is running great."
so there is some sort of situation that i should probably be aware of
Socket 462 mATX build: modern, silent, and future proof \
VOGONS
"Unlike modern systems which draw mainly from +12V rails, Socket A systems draw most of their current from the +3V and +5V rails." https://www.reddit.com/r/buildapc/comments/bl0oup/psu_suggestion_for_socket_a_retro_gaming_pc/
unclear if this should be expected to be an issue at the point where im just trying to get through POST, with no discrete GPU installed
"Make sure your PSU has at least 20A on 5v for Slot A and early Socket A boards." https://www.vogonswiki.com/index.php/Athlon_Motherboards
mine (Corsair CX650) does have exactly 20A
Athlon Motherboards - Vogons Wiki
i plugged in three HDDs just in case putting some load on the 12V might change something. it did not
the most suspicous thing about this to me is the CPUs not warming up
i was talking about this project with a friend on NYE and he asked which socket i was working with. when i said Socket A he was like "oh nooo you really shouldve gone with Intel for this time period" and said there is no end of weird issues with Socket A stuff. he may not have been wrong
i was hoping to come away from this with some clues as to which of my existing parts may or may not be functional. but now i just have more parts and even more uncertainty
not to mention less money
!!
this person tests Socket A CPUs with different PSUs, and finds that high TDP CPUs fail to POST with the newer PSUs which have weaker 3.3V/5V rails. my Athlon XP 2400+s are definitely on the power hungry side so i suspect this is what is happening on my system too

Can your PSU handle Athlon or Duron Socket A processors?
i found a cheap a Duron 700 on ebay and will be testing that once it arrives
if i had known about this stuff in advance i probably would have looked for socket 754 gear or something lol. but im gonna see this through now
i guess picking possibly the most cursed CPU socket to work with is very on brand for me anyway
we are so back
in goes the Duron 700
so i powered on and got the first signs of life in the history of this project as the pc speaker started doing the "no ram detected" beeps. i powered back down, installed the cpu cooler and... back to nothing at all. did i kill it? 😭
trying the other mobo. its the one with no pc speaker so i gotta hook up the scope again. however there is one notable difference already: the cpu gets hot in this one (i burned my finger)
todo get a thermal camera
well, nothing on the pc speaker again and there is also a slightly worrying smell. i guess it was not meant to be
the burn is also quite painful so i am giving up for now
this sure has been a way to spend money and time
the blister from the burn has calmed down a bit with the help of a big blob of moisturizer. i am somewhat typing-impaired for now though
im thinking i may cut my losses and give up on Socket A after all. im eyeing a very tempting Socket 754 board with CPU and RAM all bundled and tested
it is interesting to learn that the 12/5V issues go back a long way lol
a Socket 754 board appears
but lest life become too easy, the IDE connector placement here ensures that a 24-pin ATX plug absolutely will not fit
also i still need a cooler
24pin to 20pin adapters are luckily available locally. DOS booting next week???
also this board is the bigger mATX variant. do i have standoffs to accommodate that? ha ha ha of course not
no wait i do!!
"PC ???" bin saves the day 😍
ive installed the board + i/o shield, put in a CMOS battery and thats about all that can be done today
curiously it seems that both the cooler and adapter are ready for pickup now despite it being saturday. DOS today???
cooler installation is a bit puzzling. the caps get in the way of the clips
i could unscrew the bracket from the mobo but then it is impossible to screw it back with the cooler clip in the way
maybe if i carefully bend the caps.. 😬
@ahihi what a dumb design! is it because the part on the cooler has a bit of a curve?
@ahihi maybe you can bend it so it's more straight? 😬
@bazkie i can bend it. i am not at all convinced it will be more straight afterwards 😂
