I see you still haven't got rid of those Sanyo CG capacitors. These are not even low ESR actually.

That thin aluminium heat spreader sucks. Take a decent copper one off an Athlon 64.

Just use 30% hydrochloric acid (HCl). your avatar explains everything :D Always looking for new ways around, no matter easy or hard :) It eats aluminium like a charm. It attacks tin and lead, too, so don't put the whole chip into the acid. A few drops on the heat spreader, wait, wash away, repeat. …

I can upload a vid of popping the ihs off. It is probably the easiest part of the mod. Everything else is pretty tough. But you have to do it the way I show. It has worked for me many times but that isn’t to say that it will work every time. I saw a user on another forum (beginning of this thread) …

Would be interesting to have some values of the cpu power demand differences of these modded/overclocked K6-3+ compared to both the original K6-2+ setting and also the original clocked K6-2/3@250nm. The additional L2 cache doesn't seem to consume much. Actual power consumption varies significantly …

There are two things that really piss me off about this mobo. 1. You can set memory voltage and that's all. No CPU core or NB voltage. Not even a P-state to choose. 2. When you type in any memory timing and it doesn't work, I mean absolutely doesn't, the mobo won't recover from this no matter how …

Figured it out myself. You have to delete that Auto with back space and type in numbers. Those at AMI who designed it this way instead of drop-down lists must be genius.

Pardon my late arrival to this thread, but I couldn't help but wonder if anyone knows the rationale for disabling half the cache on the K6-2+ chips? With the Pentium Pro chips, I'm pretty sure that the difference between 256k, 512k, and 1024K was the presence of less cache, and consequently less …

It's one of a few AMD 500 series AM4 boards with PCI, COM and LPT. It's ASUS business series, so no fancy bells & whistles, but well done in general for $100 price. Supports up to 16C32T Ryzen 9 5950X, though I doubt it can actually do that with 4+2 power phases using somewhat ordinary Vishay FETs. …

I had planned to make more but things never got that far, I have a bag of PCBs and pins though not the SRAMs needed. After move is done I can do some on request. (I have PCBs for 32 and 128KB chips) Would you share your gerbers for us to start playing with? I see you have solder pads for both 0805 …

My point is that soldering pins on the bottom like that will be hacky and messy. Potential options: 1. A separate PCB with SOJ socket on it (or simply solder pads) that can be inserted vertically into the base one with the DIP pins using a SIPP-like connector. This way we can modularize the …

This is what you're looking for. 2-layer PCB, nothing special except how the pins are soldered. There's some free space left, so I would probably add a 0805 capacitor. Do we have a gerber for that? No gerber unfortunately. These were manufactured in the late 1990's. I only have a few units left and …
