you should be able to find it here somewhere http://www.madshrimps.be/gotofaqlink.php?linkid=1460 Quote:

does anyone know how the 3.3v mod exactly works? what resistors + potmeters do I have to use, and does my potmeter start at max resistance or not? |
ah, a good pic http://home.no.net/comerade/3,3v-mod.gif a 15ohm fixed and a 100ohm or larger pot appears to be better though |
just watch out when playing with voltages, expensive toys you're tinkering with. |

especially PSU's are dangerous to mess with... as I've prolly already said, the PSU from my suitcase PC trashed the mainboard, two NIC's, the soundcard, itself, the wireless mouse transmitter and the HDD fortunately, the memory and the CPU survived it what do you think JMke, is this 350W PSU not enough to power all this hardware? I think so, but the 3.3v rail is actually the only problem |
the AMD XP lives from the 3.3/5v rail, if that one is lower or faulty it can take down a 450Watt PSU that PSU might work perfectly with a P4 system though, I had a no-name 300Watt, its 5 dropped to 4.62v and the system would crash when I put my little XP1600+ @ 1800Mhz with 1.85v |
i've set my CPU to 9.5*166 (1557mhz). in windows my 3.3v rail is ~3.04volt, with my multimeter I get 3.08 volt :) |
hmm. the PSU was lying on it's side with the fan on 5V. I've blown the dirt out of the PSU and noticed the heatsinks in it were still very hot. I've put the PSU in it's normal position (with the hole for the 92mm fan up. btw there's no 92mm fan in it, only a grill) and gave the fan 12v. now my 3.3v line is stable like hell at 3.30 volt (multimeter) and 3.25volt (MBM) great, I hope the problem is fixed now. btw, the PSU is making a high-pitched sound (didn't notice that before), is that normal? |
3.28 ~ 3.29, stable. fan at 7V before RTCW:ET always crashed at 1024*768, now it's working fine again at that resolution :o |
When I read this thread it just screams at you: "ACCIDENT WAITING TO HAPPEN" ;) Quote:
