Respond, Pass, or ENTER to continue> #1/2 from: Ren on : Wed 23-Mar-1994 2:34a You won't believe this, but The Poet and I (Ren) actually tryed this trick on my Amiga. It took me like two days to decide if I really wanted to try it on my A3000, and I almost changed my mind at the last second. Here is the part you REALLY wont believe. IT WORKS! No kidding! It wasn't even that hard either. Anyone with a reasonable amount of electronics expierence could do the "conversion" The Name of this file is alittle missleading in the fact that it implies that you are changing your whole Amiga to 50mhz. In fact, you are only changing the speed of the FPU. Still, it is worth it! I rendered a frame in LightWave before the conversion, then after. After souping up the Amiga, the frame rendered 32% FASTER than before! I am writing this E-mail on my A3000 right now. I haven't had any problems at all with the computer since Poet and I did the little 'Hack' to my computer. Don't just take my word for it, I am uploading an AIBB mod so you can see for your self. Cheule will also act as a witness. (tell them your theory about computer chips Cheule) Anyway, I think thats just about all I can say. It works, it works, it WORKS! --My AIBB mod is named Rens3000.

My theory on FPUs was that the following: It's too expensive for them to have different assembly lines producing different grades of FPUs so they just produce the top grade, then label them different to keep the price high for the "top" grades. WELL - I've since talked to Dax of Creative Computers @ Lawndale (Amiga Tech) He statess that my theory is close but not exact. The TRUE story for FPUs is that Motorolla has one assembly line for all FPUs (like I had thought) , and they always TRY to make 100 mhz FPUs. But only about 10% of the FPUs produced actually pass at 100mhz. These 10% are then labeled 50mhz. Then the rest of the FPUs that didn't pass are tested at 80 mhz. Those that pass are labeled 40 mhz. Then the same for 66 mhz, 50mhz and 40mhz. So in other words, the 25mhz FPU in your a3000 has already passed a test at 50mhz!! Basically all we did in the hack was cut the trace that leads the 25mhz clock signal in to the FPU, and then dumped a 50mhz clock signal straight from the 50 mhz crystal on the motherboard. Dax also said that he owns a GVP accelerator board that comes with a 50 mhz '030 and a 50 mhz 882. On almost all GVP combo accelerators (not the a1200 ones) there is a crystal that clocks the '030 and the FPU at the same mhz, but there is a spot to add an additional crystal in case you wanna have an FPU running at a different speed than the '030. So he dropped in a 100 mhz crystal and jumpered the board to use the new crystal for the "new fpu" and now his standard 50 mhz FPU is running at 100 mhz!! He also stated that when you try to run a chip this fast a cpu fan/heatsink is imperative!! So there you have it! Not only DOES it work, but now you know why! End of item. Respond or Pass>
