![]() Except as noted on motherboards you can go down in volts ONLY IF you check the actual circuit voltage with a meter under all conditions. uF goes down with age anyway and 1 step is most always within the 20% tolerance. Going with more uF (within reason, one 'step' in standard sizes is fine) ![]() If you must substitute the safe directions are: ![]() Hard to say for sure as running too long with a bad PSU or with bad caps can damage other things.Īlways check specs on old caps and try to match. The HD and Rubycon should be fine unless the boad was overheated (poorly cooled) or connected to a shoddy power supply. So you know it's on a 5v or less circuit and 6.3v is fine. The next highest voltage on a motherboard is 5v. You KNOW it's not on a 12v circuit or it would be a 16v+ cap. Switching in a 6.3v for a 10v is okay on a motherboard. The (M) indicates the tolerance (+/- 20%) and is not part of the series number. It's sort of like a UL number or an FCC ID number but it indicates compliance with some Australian regulation.ĭ865GBF/D865PERC is on Intel's published list of boards with possible faulty Nichicon HN and/or HM series caps. Many completely different Intel boards will have this number. This doesn't have anything to do with a model number. > Intel Desktop Board D865GBF/D865PERC > It also has E210882 Silkscreened on the board. I hope someone knowledgeable with this board can help. What is the rule for replacing capacitors in terms of their values and voltages? I have a number of capacitors available but not the same values/voltages. I have some more Rubycon 2200uF 6.3v in my spares, can I replace the 4x nichicon 1200uF 16v with these? Replacing the nichicon 2200uF 10V with the Rubycon 2200uF 6.3v has had no effect.ĭoes anyone know whether my problem is related to bad caps? If yes what capacitors are the likely culprits?Ĭan this motherboard be saved? Or will other components have been damaged? Other than the nichicon 2200uF 10V, in item 1 above, all other capacitors look OK. Then there are numerous other small nichicon capacitors peppered about the board. 5x Rubycon 820uF 6.3v, 3 of them by the cpu socket, the other 2 are at each end of the DIM socket nearest the CPUĤ. 4x nichicon 1200uF 16v capacitors (also marked HD(M)) between the CPU and the back panel connectors.ģ. Is it ok to do that? The capacitor value is the same but the voltage is lower.Ģ. ![]() This was bulging so I replaced it with a Rubycon 2200uF 6.3v. 1x nichicon 2200uF 10V capacitor near the SATA-1 connector. The board has the following capacitors (hopefully the above pictures will aid understanding my text):ġ. Mine are metaalic with blue markings on top as in the previous picture. Also the yellow capacitors in line with the CPU socket are different. However it is different in that the BIOS chip is in a socket. While the picture below is not of my motherboard, it is nearly identical in looks. The fan just turns on power up and then nothing. The problem with this board is that it does not boot up. The board was given to me as not working and its history is unknown. There is a bar coded label which reads: ABBF41428624 AA C25843-407 (I assume that C25843-407 is the serial & revision) It also has E210882 Silkscreened on the board.
