Did you replace same capacity ? As i heard polymer capacitors have to be 2-3 times lower than electronic I replaced the same capacity. Since I recapped a second DFI K6XV+/66 for myself with exactly the same caps (even from the same Mouser order) I'm absolutely sure that it's not a problem with …

So it looks like 600Mhz is out of reach at 2V. Not at all! Hirsch has one which can run 6x100MHz at 1.85V! This is the result of the 9 CPUs I ordered for RaiderOfLostVoodoo and me. I didn't test with more than 2.0V (except one). When no 600 MHz is mentioned it doesn't run stable on 600 MHz@2.0V. I …

Many situations? I thought that they go up in smoke and fire in ALL situations when installing tantalums backwards 🤣. Yamaha scares me a little bit because the 47 µF caps seem to buffer +-12V and +5V. When I have a look at the voltages they obviously ignored the 50% voltage derating rule. I found in …

When I have a look at Mouser for SMD caps which might fit on the NEC board I just find Tantalum and MLCC caps besides the "original" wet caps. Which caps might Yamaha have used on their board? For me the caps on the Yamaha board look like Tantalum, what do you think? Wikipedia says "A particular …

Thank you very much for the feedback so far. Replacing bad chosen caps by Creative with better ones makes sense when recapping, I'll have a look at this. Sometimes you don't have a choice which type of capacitors to use when the space available matters. My AWE32 is populated with wet caps of a small …

I've already recapped some pieces of retro hardware. I'm now considering how to deal with sound cards. Organic polymer capacitors are superior above "wet" caps in almost all regards (except from a higher leakage current). Due to this I consider what's the best choice for recapping sound cards when …

The L0, L1, L4, L5 etc are inductors. The ones with 4R3 are 4.3uH. The ones labeled 100 are 10uH. I only agree with you up to the point that every conductor is an inductor, too. I've measured the inductivity and the resistance with an LCR meter. The result is: L0 = 8.4 µH L0 = 10 Ω L1 = 6.3 µH L1 = …
