Some power supply observations

[loafbred]

A few months ago, I built a machine for a friend using the following components, and it wouldn't do better than 2.1 GHz, but it does run at 210 bus:

Antec Smart Power 350 watt
Abit NF7-S, using onboard sound
Barton 2400-m
1GB Hyper-X PC2700
Asus Ti 4200
------------------------------------------

Just prior to building that one, I was using this in mine:

Antec True Power 430 watt
Abit NF7
Audigy2 ZS
A different Barton 2400-m
The same memory (I sold it to him)
ATI 9800 Pro

Mine ran 2.2 GHz with 1.65v core, or 2.3 GHz with 1.75v. Both were tested with cpu temp below 45*C under load.
Having recently upgraded my stuff again to an A64, I decided to put my NF7 in a new case (Antec w/Smart Power 350 watt) with my father's 2400+ and Sapphire 9600 XT.

I had used the T-bred 2400+ in my NF7 before I got the Barton, and it ran 210 bus and 2.2 GHz. Now, using another 512MB stick of Hyper-X PC2700 (which is a little better than the other two in my friend's machine, and also ran easily over 200 bus), The T-bred 2400+ isn't stable at 200 bus, nor is it stable at anything over 2 GHz, using default core voltage. It will run 333 bus with 2-2-2-11 timings, at 2 GHz. . I tried several combinations of chipset, dimm, core and AGP voltages, but nothing helped. Everything is running cool, and the only real differences are the power supplies and video cards. I can't blame the Sapphire 9600 XT, because the AGP bus is at 66MHz when running memory at 200 bus. All were using one HDD, and were tested with minimal case fans running.

Anybody else have similar experiences with those same power supplies?

Well, a 9600 Pro uses quite a bit less power than a 9800 Pro, but I still wouldn't use an SL350 with either of them while trying to overclock very high. You'd need either a TruePower 430, or it's equivalent, the cheaper SL450, to make sure you weren't running out of psu power.
