What you see is a compromise. That chip needs ESD protection but they can't just put a lid on the whole thing, the chips would overheat in a fully enclosed case. So they did the next best thing.

This means you have to keep in mind that corrosion may be present underneath those ISA slots, which may need to be desoldered in order to verify & rectify this. Very true. It looks like an easy project (find trace solder joints, solder a wire to them) but it's quite difficult when the damage is …

Always use "untested/no returns" in the description even though you know full well that it doesn't work. I could sell like a 100 of faulty boards that way to unsuspecting bidders, none of them have any burn marks on them so it would be easy. Too bad I have a conscience.

If you had put bad ecc ram or non-ecc ram, I suppose it shouldn't make any difference as far as beep codes go. If it's "bad" it's just bad. True, beep codes didn't change. The diagnostic card showed different error codes though: 8803: no RAM 8810: wrong RAM (133 Mhz are not supported in any size) …

I tried 14 different RAM configurations and none of them worked. I don't have a single ECC module so I have to buy a few to see if it's indeed the problem. The board looks decent otherwise and even works with a dual 233 configuration. Diagnostic code 8810: 64K base memory test. 1-3-1 beeps confirm …

I have a Netfinity 3500 board (93H7269) that beeps: 1-3-1 indicating a memory failure. Is it because I only have standard non-ECC RAMs? I tried a few non-ECC RAMs and it's the same beep code.

It also depends on where it comes from. If it was tossed around in a recycling center for weeks then it could be physical damage as well. SMD parts are easily knocked off, pins bent, traces scratched up and even RAM chips break quite easily. IMO the majority of "modern" GPU failures are due to a …

What I actually did was put the pin in the proper socket hole, then insert the CPU in the socket and then put the cooler on. That's actually a brilliant solution for people with limited soldering equipment/experience. It should probably work with smaller CPUs too that are extremely hard to solder …

The usual stuff: Core 2 Quad Q6700 from China. Interesting to see how C2Q and C2E prices have doubled and tripled in the past 2 years as Chinese stockpiles started to run out.
