Good point, I'll try soldering it from the top-side instead then, where the hole is still okay and connected to ground. Thanks 😀

Neither is the retail Award BIOS. I'm still not sure which is least bad.
I stuck my best one (the one that is stable at 133MHz with a Tualatin 1400S on a Slot-T slocket 😜 ) into an original Packard Bell case. Also put on a Zalman CNPS3100 over the CPU and replaced PSU fan with a Noctua Redux 80m fan so it's completely quiet. Runs Unreal Tournament like a dream 😉
I think your posts on the MS6168 upgrades are what kept me interested. I've got a v1 which is happily running a Katmai P3-550 in a low profile micro ATX case but I've always wanted a bit more and I know that the V1 can only handle P-II and Katmai P-III cpus. I can't remember how I know that though.
Having looked at the datasheet for the vcore controller, I wonder if the *only* difference between the V1 and V2 of the MS6168 is the SC1152CSW on the v1 vs the SC1153CSW on the v2? That would fit given the voltage tables for the two parts. Heh, maybe I should try upgrading my MS6168 V1 with this later chip and see if it'll handle later CPUs
edit: now I'm confused, what is the difference in the V1 and V2 except TV-out, that makes coppermine support possible? Maybe I don't need 2 boards after all
Supposedly the big difference between the two is that the V1 has an i440ZX chipset and the V2 the i440BX. Given that it only has two DIMM slots and one CPU slot that shouldn't make a lot of difference - just no ECC support in v1.
Ah, I really wish I took some pictures before I re-attached the northbridge heatsink with thermal tape now. I'm pretty sure it says it's a 440ZX in the BIOS string now that it's running the Award BIOS.
Finally starting to trust this MS-6168 v2 motherboard now that it's up and running, passes memtest at CAS2, installed an OS without issue and it's now got a 32GB SSD through a SATA > PATA adapter and a laptop optical drive. Now all it needs is a cool case.
I did get something really weird though, haven't seen it happen again and I'm not sure if it was just the system going into standby... for testing I was watching the unreal castle flyby bit and had it running for a while, then the whole computer just immediately shut off.
The only hotspot left is the MOSFET that powers the Voodoo 3 chip, so that's got a cute little ceramic heatsink on it now which makes around 10c difference
Also started using this little USB-C power delivery hotplate I got, it made moving parts around on that msata adapter far easier than an iron, even if I did burn myself on it a few times
