If the res is connected to ground it is pulling down some +V.
I'd like to know what's for too.If I read it correctly it's a 220 ohms resistor, nothing high.
If I counted correctly it's pin B21: 100/66# BCLK Frequency Select, maybe it's a permanent FSB100 hack. Is there a way in BIOS to select the FSB? Maybe for lack of selection it overclocks a lower FSB rated CPU?
Can you select 66/100 in BIOS at all?https://datasheets.chipdb.org/Intel/x86/Penti … II/24365703.PDF
Vcore is determined by the HIP + the 2 mosfets (I guess; HIP is a mosfet driver).
https://pdf1.alldatasheet.com/datasheet-pdf/v … HIP6018BCB.htmlSo I thought it could be an alternative way to raise the FSB, the motherboard has no jumpers, so only from the BIOS can you change the frequency, assuming it is available, some BIOSes are essential, and do not allow you to select other frequencies, so it would be possible for the mod to do what the BIOS cannot do.
Unfortunately I have not yet tried starting the MB, when I do, if I read 400 MHz instead of 266 MHz, it will be clear what it is for.You didn't power it on? Go turn 2000 biolche, by hand! 🤣
Post back when tested. Ciao!
Yes, I haven't turned it on yet, because first I had to change the capacitors of the VRM on the Slot1 side, then looking at the back I noticed the mod, and I immediately thought it wasn't from the factory, however I hope I won't have any nasty surprises when I do the first startup (after replacing the capacitors), if I wanted I could have tried it first, but I preferred to wait, maybe it wouldn't have started at all, three of the six were "In circuit / Leaky", the others although they seemed good, were out of tolerance (capacity), in short, having them changed all six will have made the card work (almost certainly), I hope that was the only problem, and not finding anything else to replace.
I think I have time to do a test tomorrow, or in the next few days, I currently have a full bench with various MBs, I have to remove a couple of them, and put on this and another S.423, I have accumulated several to try.
