Mobile Barton ---> PSU question (also how is this stepping?)

[charloscarlies]

I currently have an Allied 400W that says only 12 amps on the 12v rail which seems abysmally low. It's been running the system in my sig for a month or two now with no problems and several other systems before it. I'm in the process of getting a True 480, but my question is will my current PSU limit my overclock significantly on the new mobile barton I just got? Mine's an IQYHA...is that one of the better steppings?

The new setup will be:
Mobile 2600
NF7-S
KHX3000 (bh-5)
1 Raptor + 1 IDE drive
2 opticals
FX5200
Audigy 2
4 Case fans

I know the 9800 Pro liked to suck a decent amount of 12v so since I'm using the 5200 now will that make it manageable atleast?

I stepping generally better but it all depends on week and your luck.


Powersupply may limit you on your overclock , Best thing is to try it out and see where your voltages go under load. Use motherboard monitior to watch your voltages when useing Prime 95

Well I can't do 2.4 ghz without it rebooting during prime95. Must be the power supply huh?

If your KHX3000 is PC3000 ram, I'd say your ram is topping out if your running significantly over 183mhz fsb. Try some faster ram like PC3200 or PC3500. You might up your voltage on your ram a bit. Also, try relaxing your timings on your ram.

This particular PC3000 is bh-5 though so I know that isn't the problem. Ran a bunch of memtest loops and everything is fine. I tried relaxing the timings and bumping the vdimm anyways just for fun, but no dice. I'm pretty sure it's the PSU...but I guess I'll have to wait to find out.
