Combining a few posts from the last Digest (so I can disappear again because I'm too busy at the moment)... DON'T DO IT!!! The NUpowr G3 240 is MARGINAL, meaning overclocking CPU, MB bus or backside cache all lead to progressive failure of the CPU or MB. (Interware/Vimage did do a 240 as well but it was quickly superseded by the 320/400). The 2400 also needs an improved heat sink. A number of list members have disregarded this longstanding advice and burned CPUs & MBs (several have corresponded w/me offlist). I've run overclocked benchmarks and the gain, while measurable, is only 5-8%--NOT WORTH JEOPARDIZING AN ENDANGERED SPECIES. On the GLOD topic, cold flow of the solder (electromigration) is what allows a CPU to "repair itself" after sitting a long time. Then the heat reopens the solder cracks to recreate the short circuit. That's why the GLOD G3 might run a few minutes, then fail. Chuck G. is the guy to see in the USA on heat sinking. The only solutions to this particular GLOD are: A.) replace CPU B.) send it to DT&T for resoldering on their surface mount machine. They've done it successfully on a G3-400/ G3-320 (Interware) and 2 x G3-240/120 (Nupowr) (burned running at 160 mhz backside back in 1998) and failed twice on another G3-320 for me. The good news is that the currently described problem can almost certainly be repaired. The bad news is that the standard price is $250, but tell Bryan I sent you and he might drop to $200. DT&T warranty the repair for 6 months. Anticipating other concerns, I am on top of the following... No definitive word yet on a new round of G3 upgrades--it's still going forward, it is feasible, and the market is there. 700mhz is the limit because 800 generates too much heat. I said I'd drill holes in the bottom of my case, but that's not (commercially) a viable solution--and battery life falls off of the cliff. So wait, and don't ask because I won't answer until I have an answer--but I haven't forgotten for a moment. However, don't hold your breath if you have a G3 upgrade opportunity--same rules, as always--if you need it/want it, do it. IMO current CPU values would be G3-240/120 at $300, G3-240/160 at $350, G3-320/160 at $500, and G3-400/200 at $600 w/at least a 30% premium if you are a fanatic and just have to have it. A 20% discount if you luck out. So, the risk/cost of repair is arithmetic you have to sort out individually. Of course, if I get the guys to really release a new round, the bottom will fall out of the used 2400 G3-CPU upgrade market. Sidney Ho ---------- Duo/2400 List, The friendliest place on the Net!
