+5V stability mod.
http://www.overclockers.com/tips845/
How do I know which mosfet to use for this mod I have an Asus A7N8X(-X) (don't think the extra x is of any importance here) THX! -- Ugh! |

Quoting from the article: "Once you locate the core voltage regulating Mosfets (usually six of them), you will see them typically grouped in threes, though some motherboard manufacturers still use twos. On three of them, the center pin is attached directly to the +5V path coming over from the ATX connector and three of them are not. *You can determine this by taking a multimeter and checking each of them with the power on.* " |

Don't nForce2 boards like yours mostly use +12V for the CPU? It would not be a particularly good idea to short +5V to +12V... (The article is a bit older already, at that time Socket A boards mostly used +5V indeed.)

Hi, If I were doing it, I'd go into PSU and raise the +5V output little bit to benefit all the circuits needing +5V. Anyhow tolerance is +/- 5% typically. 4.75 to 5.25 is within tolerance. Such a big deal. Tony |

"Moods" wrote in message . .. http://www.overclockers.com/tips845/ How do I know which mosfet to use for this mod I have an Asus A7N8X(-X) (don't think the extra x is of any importance here) THX! -- Ugh! Wow that's nuts!.. In reality it's probably not that good of a thing either, you'll end up shifting more load to that "spare" wire as the connector not being there leads for less of a resistive path and as such more current will want to flow there until such a time that the current traveling through the wire increases to such a point that it begins to warm and it's resistance will rise until such a time that you have little to no difference at all.. your going to bypass 4.8m ohms of resistance (actually not bypass) Your going to Try to shunt around it.. but taking the wire into consideration then 9.8m ohms would be what your starting with.. and something like 3.3m ohms would be the "after" effect.. So dropping 6 m ohms isnt THAT bad.. But thinking about power consumption.. Assuming you had a 40w drop. that would be like 8 amps.. or something like .05v (5 mv) err hope I got that math right.. was just speeding through it really .. I think that the post said something that would be of more benefit than actually trying to do the mod.. Get a new psu and plug it in once and use it .. dont unplug it 100 times.. |

The guy who wrote that article seems not to realize that on most Pentium
4 motherboards, the Vcore switching power supply on the motherboard generates the Vcore from the +12 volt line rather than from the +5 volt line; and that the whole point of the 4-pin square "ATX12V" connector is precisely to do what he suggests, e.g. get more current to the appropriate part of the motherboard without any voltage loss.
