Basically im looking at speed fan and MBM and an getting these under load i believe

MOBo MONITOR
+3.3 2.67
+5 5.03
+12 12.22
-12 -12.85
-5 -5.04


Everything seems great so i should be able to oc some more. What or where can i find my 3.3v reading. The 3.3v reading is my vdimm. Also its great to find out that nothing uses -12v cause that wnet over 13.01v under load.
Im using a 350w Antec SmartPower PS.

Also which rail runs what??? And are these ok to oc some more.

Running
2100+ 12x166= 2400+ speeds
8rda+
Radeon 9700np (modded to pro)
512mb Hyperx PC3000
CDRW
DVD
Floppy
Sk-7 (ys-tek adjustable fan)
Coldcathode
5 case fans (antec fans)
Winxp pro

Is this to much for a good Antec 350w to handle. Should i discoonect some fans or are they on a seperate rail than the cpu. BTW temps under load after prime 8hrs are 34-36 max plus my ram is at 6332

Those Antec Solution series ?smartpower have a very good 3.3+5v rail combined rating (where Athlon?s draw power from) ?

300/350watt
3.3v ? ? 20/28A ? ? ? (3.3 and 5 combined 220/230watts)
5v ? ? 30/35A
12v ? ? 15/16A ? ? ? -> 180/192watts

That 350w should be plenty for even a 9700 and Athlon 2400+.

I have an 350 Enermax FMA loafing along powering a Celeron-T my M/B readings are ?

2.5 ?2.53
3.3 ? 3.38
5v ? ? 5.17
12v ? ?12.42

Your 350w Antec will hold that system just fine, as you already know. Disregard the negative voltages- your mobo doesn't actually use them. They're strictly for backward compatibility with some older mobos and serial devices. The reason your board reads the actual dimm votage rather than the 3.3v is probably because the dimm voltage is adjustable in the bios. The spec calls for 5% variation in voltage, you're well within that. Check it out at www.formfactors.org.

While the p4 systems draw cpu power from the 12v rail, I don't think that's true for AMD systems, despite the Firingsquad article... Why else would AMD be so careful about the need for 3.3 and 5v combined power ratings?

No, Firingsquad are right. Look here scroll down to page 7 & 8, they list the XP1800+ and XP2100+ as using the 12V.

I wonder why Antecs 12V rails are so weak compared to Enermax.
