I really prefer this build over the smaller more diy WeeCee build. But i really want to build one with a 3d accelerator. To be able to build one that plays later DOS, 98 and even some early XP games would be great. I have a PCI Geforce FX card and would love to use that with something like this. Is …

Knowlege of using a multimeter to test caps would be an idea but you'd see the bulges if they were faulty. That is indeed often but not necessarily always the case . Capacitors can fail/got out of spec even with no apparent outward sign of failure . That being, some of the caps do look possibly …

Caps in the VRM near theCPU are 100% defective. Epox mainboards had a lot of these issues back then (Socket 7, Socket 370). The siren sound might indicate wrong or dirty (core-) voltages. Otherwise these Epox boards were great! Thanks some caps are bulgy. I will just order them off Mouser and give …

Haven't heard the siren sound before but you can do a loose connection elimination. Remove and install components and then if it doesn't go away swap out components with others like the gpu and memory to find the offender.

My Socket 370 PC used to work but now i just get a siren sound, no video, no keyboard light. I tried switching the PSU but i get the same problem, sometimes it powers on without the Siren sound but still no boot. Thermal Paste was already replaced in this with MX4 months back and as you can see in …

Via So370 chipsets support the ISA bus, so it could work. You might need some extra passive bits and pieces (SMD resistors & caps) here and there though. Best bet would be to find a pic of a version of the board with slot present and compare all the stuff around it with yours. Here's a half-decent …

Just use replacements of the same type, no point in going with polymers unless you have specific needs (extremely low ESR on mid-00's boards for example). Even if you use electrolytics at this point they will probably outlive other hardware components, just think about how long the caps you want to …

Thinking about recapping my old motherboard with Polymer capacitors. Say for example it has a electrolytic 1000uf 50v cap. Can the Polymer cap also be 1000uf 50v? I’m not much of expert on capacitors but i hear polymer caps from a reputable brand are just better all around caps since they last …

If your intent is also to do DOS gaming on this build, keep in mind that neither the AWE64 nor the Audigy 2 have an actual OPL3 FM synthesizer chip on board. The AWE64 has a Creative-produced clone chip that doesn't exactly sound the same. For newer DOS games that support General MIDI, this might …

How can you have 50A on the 5v rail, which would mean 250 watts, if the max combined load on 3.3v and 5v rails is 130 watts? There has to be a typo somewhere, or there is something I am missing. EDIT: The manual from the Corsair web site says 25A for the 5v, which makes much more sense . tx850m.png …

The RM850x has 150W combined on 3.3V and 5V rails . The TX850M only has 130W . The official price difference is 20 US$, so I would recommend the RM850X .
